    FIELD OF THE INVENTION
    [001] The present disclosure relates to an adjustment actuator for a comb with adjustable spacing of an apparatus for cutting hair, wherein the adjustment actuator comprises an actuator that is configured to drive a movable portion of the comb with adjustable spacing in relation to a set of blades of the hair-cutting apparatus, and a drive system for coupling the actuator and the movable comb portion, the drive system comprising a reduction gear unit. The present invention further relates to an adjustable spacing comb comprising such an adjustment driver and to a hair trimming apparatus comprising such an adjustable spacing comb. BACKGROUND OF THE INVENTION
    [002] Apparatus for hair cutting, particularly electrical hair cutting apparatus, are well known and may include finishing machines, hair clippers and shavers. Electric hair trimming devices may also be called electrically powered hair trimming devices. Electric hair trimming devices can be powered by an electrical energy source and/or by energy storage devices, such as batteries, for example. Electric hair trimming devices are generally used to trim hair on the (human) body, in particular hair and beard, to enable an individual to look well groomed. Electric hair clippers are often used to cut animal hair.
    [003] The document US 6,968,623 B2 discloses a hair trimmer comprising a body, a cutting head including a set of blades, an adjustable comb, the comb being movable in relation to the set of blades, an electric motor to actuate the blade assembly to effect the cutting action and an actuator assembly that is capable of moving the comb relative to the blade assembly between a fully retracted position and a fully extended position, the actuator assembly comprises a comb device , a comb button connected to the comb device, the comb button being operable to adjust the comb position in relation to the blade set, and a movable lock button in relation to the comb button, with the comb button latch selectively prevents and allows movement of the comb knob in relation to the body. Consequently, manual adjustment of the comb length is made possible.
    [004] EP 2,500,153 A2 discloses an apparatus for cutting hairs comprising a housing; at least one hair cutting device supported by the housing and adapted to facilitate hair cutting, said at least one hair cutting device comprising a blade selectively movable with respect to the housing and adapted for cutting hair; an adjustable comb assembly including a comb selectively movable with respect to the blade, and a comb drive assembly operatively coupled to the comb; a control circuit in the housing and in communication with said at least one hair-cutting device; and a touchscreen to receive at least one "user action" (that is, an action, such as a touch on a screen, performed by a user), with the touchscreen being configured to send at least one command signal to the control circuit in response to receipt of said at least one user action, the control circuit being configured to control an operation of the adjustable comb assembly, and the adjustable comb assembly operation including the action of the comb drive assembly to move the comb relative to the blade to a selected haircut length setting of the hair trimmer.
    [005] The patent US 2008/163495 A1 discloses a hair cutter with a motorized cutting guide comprising a motor connected by a shaft to the cutting guide. The cutting guide is activated by a program available through a microprocessor, which suggests several options for the user. The user can operate the cut guide in manual mode and in automatic mode. The user can operate the cut guide by pressing virtual buttons on a touch screen.
    [006] A comb of a hair-cutting apparatus, particularly a spaced comb, may generally be arranged as an attachable comb or an integrally formed comb. A spaced comb generally separates a set of blades from the skin hair-cutting device when the device moves in a direction of motion relative to the skin during operation. Consequently, the spaced comb can make it possible to cut hairs to a desired length, that is, to a desired length of hair remaining on the skin.
    [007] Conventional hair cutting apparatus may be provided with a set of accessory combs, each of which is associated with a different hair length. Consequently, a device user basically needs to replace one attachable comb with another to change the cut length. Furthermore, manually adjustable clamping combs are known, as disclosed in US 6,968,623 B2. Additionally, motor-equipped adjustment combs have recently been presented, as for example disclosed in EP 2,500,153 A2. Typically, motor-equipped adjustment combs comprise a movable portion of the comb that is movable relative to a blade assembly of the hair-cutting apparatus, the movable comb portion being coupled to an actuator, particularly an actuator. electromotor and/or an electrical propulsion system.
    [008] However, it has been observed that operating a motorized adjustment comb frequently presents several disadvantages. It is often impractical for the user to operate the comb with adjustable spacing accurately and precisely, as in general very conventional control elements such as push buttons, control levers etc are provided. These control elements often provide a predefined sensitivity to user input. In other words, a single input action by the user can cause a definite motor response so that the adjustable spacing comb is moved by a defined distance or pitch. Basically, the same applies to conventional touchscreens as shown in EP 2,500,153 A2.
    [009] Consequently, inaccurate positioning of the adjustable spacing comb in the given adjustment range (which may include covering considerably long distances in the adjustment range) may be considered time-consuming. In addition, adjusting the adjustable spacing comb can be difficult as conventional control elements often require considerably large minimum increments of adjustment movement as indicated above. Consequently, operating a motorized adjustable spacing comb by means of conventional control elements can be considered a compromise between the speed of adjustment and the accuracy of the adjustment.
    [010] Due to the lack of operational efficiency and adjustment of the comb arrangements with adjustable spacing mentioned above, the operation of the hair trimmer can be more complicated. Thus, it would be advantageous to simplify the action of adjusting the comb with spacing. It would be additionally advantageous to provide a comb with adjustable spacing and an adjustment trigger, therefore, which can be operated by the user in a way that saves time and is highly accurate.
    [011] Thus, there is still room for improvements in length adjustment mechanisms. BRIEF DESCRIPTION OF THE INVENTION
    [012] It is an object of the present invention to provide a hair trimming apparatus, a comb with adjustable spacing for a hair trimming apparatus and an adjustment driver for such a comb with adjustable spacing that can solve at least some of the problems mentioned above . In particular, it is an objective to provide an adjustment trigger for a comb with adjustable spacing that can ensure simplified operability and, more preferably, more options to choose from for a user. It would be additionally beneficial to seek improvements in tuning speed and tuning accuracy and precision. It would be additionally advantageous to provide a corresponding method for operating a comb with adjustable spacing.
    [013] According to a first aspect of the present disclosure, an adjustment actuator for a comb with adjustable spacing of an apparatus for hair cutting is presented, the adjustment actuator comprising: - an actuator that is configured to drive a movable comb portion of the comb with adjustable spacing relative to a set of blades of the hair-cutting apparatus, and a proximity-sensitive or touch-sensitive sensing element, particularly a user action interface for gesture control, wherein the sensor element is configured to detect user actions applied to the sensor element and produce a user action signal that is derived from the multifaceted user action, and
    [014] where the actuator is operated based on user action. The adjustment actuator according to the first aspect of the present disclosure comprises a control unit coupled to the actuator and the sensing element, the control unit being configured to convert the user action signal into an actuator operate signal. The control unit is configured to set an adjustment span value based on a detected speed of user action.
    [015] This aspect is based on the understanding that the sensing element - which is the touch-sensitive sensing element, but which can also be considered a proximity-sensitive sensing element - can allow data entry actions by the user that can induce both a precise positioning like a quick positioning of the movable comb portion. This is possible since the sensing element is able to detect multifaceted user action. On the one hand, the user can operate the sensing element slowly and by means of small increments (touches). This can allow for accurate positioning of the moving portion of the comb. On the other hand, the user can operate the sensing element quickly and through large increments (touches). The operation of the sensing element can generally comprise the application of touching movements or sliding action on a sensing surface of the sensing element or at least in proximity to the sensing element. Consequently, the sensing element can be configured and/or operated to detect dynamic properties and to display “simulated” inertia properties. By applying quick and considerably long touches to the sensing element, the movable comb portion can be moved a considerably long distance. On the other hand, the user can drag lightly and slowly over the sensing element in order to move the movable comb portion in considerably small increments. The sensing element can be arranged as a touch-sensitive surface (“touchpad”) and/or a touch-sensitive screen.
    [016] As used here, multifaceted user actions can involve an input operation that includes more than just enabling or disabling (or checking or unchecking an option). In contrast, one can contemplate “multidimensional” user operations. In general, additional information can be obtained from the user's multifaceted actions. By way of example, multifaceted user actions may be indicative of at least two of the following input features or elements: input tap direction, input tap speed, input tap amplitude, input tap presence, presence of input touch, presence of double input tap, presence of multitouch operations, presence of pressing, presence of movement patterns, etc., and combinations thereof. Multifaceted user actions can also be called gestures, particularly touch gestures. In other words, more generally, multifaceted user actions can be called multi-aspect inputs, multi-dimensional inputs, and/or multi-feature inputs.
    [017] As shown in EP 2,500,153 A2 mentioned above, touch screens can be used to allow simple operations such as moving a comb portion in a defined increment in response to a respective tap on a certain field of the touch screen to the touch. Such a hit should be called a simple user action and/or a conventional user action. Consequently, conventional devices can, if at all, enable “one-dimensional” user operations. This may, for example, require that respective touchscreen fields be assigned to respective simple user commands. For each user command a respective field may be required (eg “slow extension”, “fast extension”, “slow retraction”, “fast retraction” etc.).
    [018] Therefore, an adjustment actuator in accordance with the present disclosure eliminates several disadvantages inherent in conventional user operating approaches to motorized comb adjustment actuators. The sensing element can provide an entry surface. More particularly, at least a sub-portion of a touch-sensitive layer or a proximity-sensitive layer can be selected and/or activated for detection of adjustment combs operating commands.
    [019] Generally speaking, the sensing element can be called the length adjustment sensing element. However, the sensing element can be arranged as a multi-function sensing element. This may involve the fact that the sensing element can be operated in several different operating states. Operational states can involve adjusting (length) the comb, adjusting the cutting speed, enabling/disabling the safety lock, enabling individual stored user settings, etc.
    [020] Obviously, the sensing element can be incorporated in or covered by a housing portion of the hair trimming apparatus and/or the adjustment driver. For this purpose, sensitive layers can be used according to operating techniques such as "touchpad" (touch-sensitive panel) and/or "touchscreen" (touch-sensitive screen) that do not require contacts in the sensitive layer to detect user action . By way of example, the sensor element may be arranged as a touch sensitive region on a surface of the housing portion of the hair trimming apparatus. The term “touch sensitive” may involve proximity and/or contact detection sensitivity. Additionally, the user can operate the sensing element with the use of their fingers or thumbs. However, you can also use other data entry tools such as a stylus pen and/or similar data entry instruments.
    [021] The adjustment trigger according to the above aspect can have the additional advantage that a single sensing element can be used to extend and retract the movable comb portion. Basically, the sensing element can detect opposite input touch directions. Consequently, the direction of the entry movement can be "translated" into an extension or retraction movement of the movable comb portion.
    [022] Depending on a detected level of input speed, one can select respective modes of operation (in terms of retract/extend speed, retract/extend increments and/or motion transpose or retract/extend time delay ). Consequently, a relatively fast user action touch can trigger a mode of operation in which an inertial behavior of the sensing element is simulated by activating an excess motion or time delay, which may include an adjustment motion in response. the user action tap is present for a longer period than the initial input tap.
    [023] According to an adjustment trigger mode, the user action signal is indicative of at least one signal component selected from the group consisting of input speed, input direction, input drag length, input drag length. entry path, and combinations thereof. Consequently, enhanced user action information can be derived from an input action applied to the sensing element. The sensed direction of an input can indicate whether an extension or a retraction of the movable comb portion is desired. A detected input drag (or stroke) length can qualitatively and/or quantitatively indicate a desired absolute or relative length adjustment level.
    [024] Signal components can also be called signal characteristics. Preferably, the user action signal is indicative of at least two signal components selected from the group consisting of input velocity, input direction, input drag length, input path length, and combinations thereof. Input speed detection can comprise detection of maximum speeds and/or average speeds of a touch or drag as user action during the execution of a gesture. Input speed detection can be based on detecting a time interval that is actually required to perform a user action, particularly a gesture as a user action, or at least a part of it. Input direction detection can comprise the approximate detection of instantaneous and/or general directions of a touch or drag as a user action during the execution of a gesture. Coarse direction detection may involve assigning detected inputs to defined main input directions (eg ±X, ±Y, North <> South, East <> West etc.). In general, direction detection can also involve detecting a positive/negative sign of a touch or drag action by the user. Additionally, one can also contemplate the more accurate detection of the directions of touch or drag actions by the user.
    [025] In another embodiment, the control unit is preferably additionally configured to set an adjustment direction based on a detected user action direction.
    [026] As previously mentioned, the user action signal can be indicative of at least one value selected from the group consisting of input command speed, input command direction and input command amplitude, particularly the speed of the input stroke, input stroke direction, input stroke amplitude, and combinations thereof. In general, the actuator operating signal can be indicative of at least one value selected from the group consisting of adjustment direction, relative adjustment range, absolute adjustment range, relative adjustment compensation, absolute adjustment compensation, adjustment speed , setting time, and combinations thereof.
    [027] In yet another modality of the tuning trigger, the control unit is additionally configured to adjust length adjustment increments depending on the speed of detected user action, with the actuator operating based on a defined length adjustment increment . Consequently, the tuning drive can be operable in a plurality of tuning speed ranges, which may also be called tuning "gear" ranges. However, ranges of adjustment “gears” should not be interpreted in a limiting sense as necessarily referring to fixed (mechanical) gear ranges. Instead, speed control and speed adjustment can be based on a variation of electrical voltage across the actuator (or motor) of the tuning driver, for example. Therefore, the definition of virtual gear can be used (based on respective electrical voltage ranges). Furthermore, the adjustment speed can basically be infinitely (or non-incremental) adjustable by the respective variation of the electrical voltage. This may involve the condition that the tuning speed can be varied in small increments so that really small tuning steps can be present.
    [028] In a sample configuration, the tuning trigger can be operated in a coarse tuning mode and a fine tuning mode, depending on the detected input speed. Coarse tuning mode can comprise incremental step size responses to a single user action event in the range of about 0.5mm to about 5mm, the value applied depending on the amplitude of a detected input. The fine-tuning mode can comprise incremental step size responses to a single user action event in the range of about 0.1 mm to about 0.5 mm, with the value applied depending on the amplitude of a detected input . More generally, at least one distinct first and second operating modes can be selected based on at least one value that can be derived from the more detailed information obtained from the detected user action.
    [029] In yet another modality of the trim trigger, the control unit is additionally configured to convert a slow user action motion into a small length adjustment increment, the control unit being additionally configured to convert a motion Fast user action in a large increment of length adjustment. Preferably, the control unit is additionally configured to convert a small range of motion from user action into small absolute length adjustment motion. More preferably, the control unit is additionally configured to convert a large range of motion from user action into large absolute length adjustment motion.
    [030] Consequently, the control unit can be operated either to “amplify” (or increase) the user action detected in a large adjustment response of the comb or to “reduce” the user action detected in a small adjustment response of the comb. Consequently, a slow user action movement can result in output in precise incremental steps, whereas a fast user action movement can result in output in relatively large increments.
    [031] In general, the present disclosure uses the idea that the activation impulse applied by the user on the sensor element and a corresponding data processing activity performed by the control unit can be (physically) decoupled from each other, from so that a respective operating mode detection algorithm can intervene between the impulse of the user action and the determination of the corresponding actuator operating signal. In other words, the operating mode detection algorithm can detect or instead predict whether the user wants a fast response or a slow response. This can additionally result in a movable comb portion that moves quickly towards a longer length setting range (absolute and/or relative), and a movable comb portion that moves slowly and precisely towards a range shorter length definitions (absolute and/or relative).
    [032] In yet another modality of the adjustment trigger, the sensing element is configured to detect touch gestures and/or gestures in the vicinity of the sensing element. Preferably, the sensing element is configured to detect a sliding action performed by the user. Input gestures can generally comprise swipe, pinch, zoom, and flick actions. As used here, a swipe entry can also be called an entry touch. A gliding input can be induced by dragging a finger (or thumb) across a touch-sensitive surface or sensitive to the proximity of the sensing element.
    [033] In another preferred modality of the adjustment trigger, the sensor element comprises a touch-sensitive surface, which includes (or is coupled to) at least one tactile sensor. The touch-sensitive surface can be formed of at least one flexible metal sheet, particularly a conductive or capacitive flexible metal sheet. The touch-sensitive surface can be formed by or coupled with a flexible printed circuit board, for example. The sensing element can be arranged as a “touchpad”, a “trackpad”, a touch screen and/or similar gesture sensitive input interfaces, preferably contact and/or proximity sensitive input interfaces.
    [034] It is worth mentioning in this regard that, in some modalities, a flexible printed circuit board can be used that can be arranged as a capacitive and/or inductive sensor capable of detecting variations in capacitance and/or inductance. In some specific embodiments, the capacitive and/or inductive sensor may be remotely disposed of the touch-sensitive surface. In other words, a corresponding sensor can be disposed within the housing of the hair-cutting apparatus. For this purpose, at least one signal transmission element can be arranged between the sensor (internal) and the touch-sensitive surface (external). The at least one signal transmission element can be arranged as a metal transmitter, for example a metal spring connecting the sensor (internal) and the touch-sensitive surface (external). The metal spring-based signal transmitting element may further comprise a metal plate which is coupled to the touch-sensitive surface.
    [035] On the touch-sensitive surface, capacitive and/or inductive manipulations can be applied by the user when performing an input operation. The corresponding signals that are indicative of input operation can be “transferred” to the (internal) sensor. Preferably, at least two signal transmission elements can be used. More preferably, at least three signal transmission elements can be arranged at separate locations on the touch-sensitive surface. As a consequence of the arrangement of multiple signal transmission elements, multidirectional user action can be detected. Preferably, each signal transmission element is assigned to a respective sensor element of the sensor.
    [036] According to yet another modality of the adjustment trigger, the sensing element is a capacitive sensing element or a conductive sensing element, and the sensing element is preferably a multi-touch sensing element. Touch sensitive capacitive sensing elements and touch sensitive conductive sensing elements are generally known to those skilled in the art, particularly in connection with mobile devices and/or interfaces used in computer technology. Additionally, so-called multi-touch sensor elements are generally known to those skilled in the art. However, the adoption of these techniques should not be interpreted as potentially making the present disclosure obvious.
    [037] In yet another embodiment, the adjustment trigger additionally comprises a feedback unit, which is operatively coupled to the control unit. Preferably, the control unit is configured to provide user guidance indicating that user-entered data is active in the sensing element. Preferably, the control unit is additionally configured to provide feedback to the user in response to detected user action. In general, the sensing element and the feedback unit can be fully implemented in a touch screen unit. However, alternative modalities can also be contemplated that include a sensor element and a feedback unit that are arranged separately. User feedback may generally comprise an indication of an actual and/or selected length of the moving comb.
    [038] The above modality can also be further developed in the feedback unit to comprise at least one of an optical feedback element, an acoustic feedback element and/or a tactile feedback element. A tactile feedback element can be arranged as part of a haptic response system and includes vibration elements, for example. An optical feedback element can be arranged as a luminous feedback element such as an LED. Furthermore, a touch-sensitive screen can be operated to define at least one optical feedback element.
    [039] Particularly, in connection with optical feedback elements, the user can be provided with visual guidance to indicate where and how a comb length adjustment input can be applied to the sensing element. In this context, it may further be preferred that the feedback unit comprises an array of optical feedback elements, particularly an array of sequential lights (optical elements) that are selectively operable to indicate a direction of possible user action. Sequential lights can indicate either the direction of the entrance or a location or region where user actions can be applied.
    [040] According to another aspect of the present disclosure, a comb with adjustable spacing is presented for an apparatus for cutting hair, wherein the comb with adjustable spacing comprises a movable comb portion that is arranged to be movable with respect to a housing portion of the hair-cutting apparatus, and an adjustment actuator in accordance with at least some of the embodiments discussed herein. In other words, the movable comb portion is movable with respect to the housing portion of the hair-cutting apparatus. In general, the spaced comb can be arranged as a fixable and removable spaced comb. Alternatively, the spaced comb can be arranged as a spaced comb supplied integral or integrally, which cannot be removed from the hair trimmer. The movable portion of the comb may comprise a plurality of teeth of the comb that can divide and guide the hairs when the hair-cutting apparatus, including the comb with adjustable spacing, is moved through the hairs to cut them to a selected length.
    [041] In yet another aspect of the present disclosure, an apparatus for cutting hair, particularly a finishing machine or hair trimmer, is disclosed, wherein the apparatus for cutting hair comprises a housing portion, a cutting unit , including a blade assembly, and an adjustable spacing comb, in accordance with at least some of the embodiments described herein. In general, the hair trimmer can be considered a hair trimmer equipped with an electric motor. Consequently, a motor can be provided to drive the set of blades. Generally, the blade assembly may comprise a stationary blade and a mobile blade, the mobile blade being movable relative to the stationary blade. The movable blade can be driven relative to the stationary blade, particularly oscillatingly driven. The movable blade and the respective stationary blade may comprise cutting edges which can cooperate to cut the hairs.
    [042] In general, the hair-cutting apparatus may comprise an elongated housing comprising a first end and a second end that is opposite the first end. At the first end of the housing, a cutting head can be arranged. The second end of the housing may also be called the cable end.
    [043] In one embodiment of the hair-cutting apparatus, the sensing element is imperceptibly integrated into the housing portion. This may involve the fact that the sensing element is hidden in the housing portion. Preferably, the sensor element, particularly a touch-sensitive or proximity-sensitive metal foil, is covered by a wall of the housing portion. This can be advantageous since in this way an integrally shaped housing portion can be provided which has a reduced tendency to accumulate dirt. Additionally, forming the device to be waterproof can be facilitated. However, as indicated above, alternatively or additionally, the hair trimmer can be provided with a touch-sensitive screen that can be used to detect multifaceted user action and, at least in some modalities, provide feedback to the user, particularly guidance feedback.
    [044] According to another aspect of the present disclosure, a method is presented for operating a comb with adjustable spacing for an apparatus for hair trimming, the method comprising the following steps: - providing an adjustment actuator comprising a actuator to actuate a movable portion of the comb of the comb with adjustable spacing, - provision of a proximity sensitive or touch sensitive sensing element, particularly a user action interface for gesture control, - multifaceted user action detection applied to the element sensor, - production of a user action signal derived from the detected multifaceted user input data, - provision of a control unit (68) coupled to an actuator (52) and sensor element (64) to convert the input signal the user on an actuator run signal, where the control unit (68) is further configured to set an adjustment span value based on a speed. and user input detected, and-actuator operation (52) using the actuator operation signal.
    [045] Preferably, the method can use the comb with adjustable spacing and the adjustment trigger, as discussed here. Preferred embodiments of the disclosure are defined in the dependent claims. It is to be understood that the claimed method has preferred embodiments similar and/or identical to the claimed device and as defined in the dependent claims. BRIEF DESCRIPTION OF THE FIGURES

Respective housing portions 12 of pile cutting apparatus 10 are indicated in Figure 3 and Figure 4 by dashed lines. Consequently, the internal components of the pile cutting apparatus 10 are visible.
    [063] With specific reference to Figure 3, the adjustable spacing comb 26 is further described. The adjustable spacing comb 26, also referring to Figure 1 and Figure 2, may comprise sliding supports 34 that can cooperate with a device 42 that is disposed in housing 12. In general, a snap-on assembly of the sliding supports 34 in the device 42 can be provided. At least a substantial portion of the spaced comb 26 can be considered a movable portion of the comb 40. As can be seen in Figure 3, the movable comb portion 40 can be coupled to the device 42 and consequently moved together with the carriage 42. driving the device 42 and the movable portion of the comb 40, an engaging member 44 can be provided which is coupled to the device 42. To operate or drive the movable portion of the comb 40 with respect to the blade assembly 16 (see Figure 1), an adjustment drive 50 can be provided which may also be called an adjustment drive system. In other words, the tuning actuator 50 can be considered a motorized tuning actuator 50.
    [064] The adjustment actuator 50 may comprise an actuator 52, or more particularly, an electromotor. The filter actuator 52 can be coupled to a reduction gear 54. The reduction gear 54 can be coupled to a transmission element 56. In general, the transmission element 56 can be arranged to convert a rotary output movement of the actuator 52 and the reduction gear 54, if any, in a basically longitudinal positioning movement of the movable portion of the comb 40. A respective longitudinal direction is indicated in Figure 3 and in Figure 4 by a double arrow represented by the reference numeral 58.
    [065] As can be seen in Figures 3 and 4, the transmission element 56 can be arranged as a filament spindle, particularly a small pitch spindle. Accordingly, the transmission element 56 can be arranged to be configured in pivotal movements, see the curved arrow represented by reference numeral 60 in Figure 3. The transmission element 56 can be configured to engage the engagement element 44 so as to push. or pulling the device 42 and, consequently, the movable portion of the comb 40. In some embodiments, the transmission element 56 may be arranged as a rack element. In some embodiments, transmission element 56 may be arranged as a connecting rod element. In general, the actuator 52 can be mechanically connected to the device 42 and, in the assembled state, to the movable portion of the comb 40.
    [066] To operate the Trim Trigger 50, respective control elements can be provided. To that end, the adjustment trigger 50 may comprise a sensor element 64, particularly a sensor element 64 sensitive to user gestures. Sensor element 64 may be arranged as a touch-sensitive sensing element and/or a proximity-sensitive sensing element 64. The sensing element 64 may be arranged as a sensing element 64 extending over an area, for example, a sensing element 64 which basically extends in two dimensions. Obviously, sensor element 64 can include a curved surface. In accordance with the present invention, sensor element 64 is configured to detect relatively multifaceted user action that is indicative of additional or enhanced user action information. By way of example, user actions may comprise sliding actions, eg user touches on sensor element 64.
    [067] The sensor element 64 can be coupled to a control unit 68. The control unit 68 can receive a user action signal sent by the sensor element 64. The control unit 68 can monitor the sensor element 64. The unit controller 68 may comprise a processing unit. The control unit 68 can convert the detected user action into an actuator operating signal that can be transferred to the actuator 52. Consequently, there is no connection for power transmission or power transmission between the actuator 52 and the sensor element 64 Instead, electrical signals can be transferred from sensing element 64 to actuator 52 via control unit 68. As indicated above, the user action signal can be indicative of additional information such as input speed, input amplitude , input direction and respective information derived from that signal. Based on the additional information, the control unit 68 can process an operating signal from the resulting actuator that can be used to operate the actuator 52.
    [068] As illustrated in Figure 3 by arrows 70, 72 indicating opposite directions, the control unit 68 can be configured to derive a user action direction from the user action signal. As a result, the control unit 68 can operate the actuator to extend or retract the movable comb portion 40, depending on the sensed direction of user action 70, 72. Therefore, multiple functions can be assigned to a single sensor element 64 There is no need to separately set a specific operating mode on the sensor element 64, as the user can apply a multifaceted action (gestures). Along with detecting the direction of user action 70, 72, the control unit 68 can derive a desired length adjustment value from the user action signal. The length adjustment value can be obtained from the speed of the input (touch) and/or the amplitude of the input (touch) detected by the sensor element 64. Consequently, the control unit 68 can operate the actuator accordingly, so to induce a desired length adjustment action.
    [069] Further reference is made to Figure 4. An extended state of the movable portion of the comb 40' is indicated in Figure 4 by a respective dashed line. As illustrated in Figure 4, the adjustment trigger 50 may further comprise a feedback unit 74 capable of providing the user with feedback in response to a user action and/or user feedback. In general, the feedback unit 74 may be arranged as an optical feedback unit, a tactile feedback unit, an acoustic feedback unit, and combinations thereof. The feedback unit 74 and the sensor element 64 may be disposed at separate locations in the hair trimming apparatus 10, particularly in the housing portion 12 thereof. However, in at least some embodiments, the feedback unit 74 and the sensor element 64 are disposed in the same region as the hair trimming apparatus 10, particularly in the housing portion 12 thereof. Feedback unit 74 and sensor element 64 can overlap at least partially. Feedback unit 74 and sensor element 64 can be integrally formed as a combined input/feedback interface, such as a touch screen.
    [070] In this regard, further reference is made to Figure 5 and Figure 6. Figures 5 and 6 illustrate exemplary embodiments of an adjustment actuator 50 according to the present disclosure, showing variant configurations of respective feedback units 74. As illustrated in Figure 5, the feedback unit 74 may comprise a display 76, particularly an LCD display or an LED display 76. In general, the display 76 may be arranged to provide visual feedback and/or guidance to the user. Display 76 may be arranged to display graphic symbols and/or alphanumeric information. The display 76 can be arranged as a multi-function display capable of showing information unrelated to the adjustment comb length setting. For example, the display 76 may be arranged to display a state of charge of a battery of the hair trimming apparatus 10 and/or a selected hair trimming mode of operation.
    [071] With regard to setting comb length adjustment, display 76 can be arranged to illustrate alphanumeric information related to comb length. Additionally, the display 76 can display user guidance information indicating that the user can select a desired tuning setting by applying a multifaceted user action to sensor element 64. As can be seen further from Figure 5, the The feedback unit 74 may also comprise at least an array 80 of visual feedback elements 82 which may also be called optical feedback elements 82. In general, the feedback elements 82 may be arranged as a light-emitting feedback element, like a light emitting diode (LED). Preferably, array 80 can be arranged as an array of sequential lights 80. As shown in Figure 5, two arrays 80 can be disposed in housing 12 of the hair trimming apparatus. For example, arrays 80 of feedback elements 82 may be disposed at opposite (side) ends of sensor element 64 (as indicated in Figure 5 by dashed lines). Arrays 80 of feedback elements 82 may be disposed adjacent to a region in which sensor element 64 extends.
    [072] Such an arrangement can have the advantage that the sequential light arrays 80 can clearly indicate that the user can adjust the length of the comb by dragging the sensor element 64 in the desired direction (arrows 70, 72) to extend or retract the movable portion comb 40. Each of the feedback elements 82 can be selectively turned on or off. In addition, feedback elements 82 can be operated as in a sequential light array so as to clearly indicate directions 70, 72. However, feedback elements 82 can also be operated to indicate absolute length adjustment settings and/or relative, as absolute and/or relative length fit values.
    [073] As can be seen from Figure 6, the feedback unit 74 may further comprise an integrated touch screen 86, capable of detecting user action and providing user feedback in response to user action and/ or provide the user with guidance associated with the user's action. Figures 5 and 6 show exemplary feedback elements activated 82 in a hatched mode. In general, the touchscreen 86 may be arranged to display graphic symbols and/or alphanumeric information. This may involve the proviso that "simulated" sequential light arrays 80 including a plurality of feedback elements 82 can be displayed by the touch screen 86. In addition, a highlighted user guidance element 88 can be displayed on the screen touch sensitive screen 86 to indicate that the user can apply an action directly to sensor element 64 that is disposed as part of or associated with touch screen 86. User guidance element 88 can be shown in addition to or alternatively to the light arrays Sequentials 80.
    [074] Figure 7 illustrates a top view of another exemplary modality of an apparatus for cutting hair 10 provided with a comb with adjustable spacing 26 and an adjustment actuator 50 for the comb with spacing 26. fit 50 comprises yet another exemplifying layout of a user action. A sensor element 64 is provided disposed in a central region of the housing portion 12. With respect to user feedback, the sensor element 64 may be basically passive. Sensor element 64 may comprise a touch-sensitive surface disposed between two arrays 80 of visual (optical) feedback elements 82. Accordingly, arrays 80 can be operated as arrays of sequential lights to indicate the location of sensor element 64 and its respective surface where user action can be applied, for example, by dragging the sensor element 64. Additionally, a display 74 capable of displaying graphic symbols and/or alphanumeric information can be provided.
    [075] In some embodiments, the sensor element 64 may be further coupled to a feedback unit capable of providing tactile feedback (not shown in Figure 7). For that purpose, corresponding vibration elements may be provided in the vicinity of the sensor element 64.
    [076] With further reference to Figures 8 and 9, exemplary modalities of pile cutting apparatus 10 are illustrated that are equipped with a respective comb with adjustable spacing 26. Figure 8 shows a perspective view of a pile cutting apparatus 10 being held by a user. The pile trimming apparatus 10 may further comprise an adjustment actuator for the comb with adjustable spacing 26 (not shown in Figures 3 and 4). The user can trigger the trim trigger when operating the sensing element 64, particularly when applying gestures (slide actions, taps etc.) to a touch-sensitive and/or proximity-sensitive surface. In general, the adjustable spacing comb 26 or, more particularly, a movable comb portion 40 (referring to Figure 9) thereof is movable relative to the blade assembly 16 of the hair-cutting apparatus 10 (referring to Figure 9). Figure 1) to adjust a distance between the adjustable spacing comb 26 and the blade assembly 16. By way of example, the movable spacing comb 26 can be extended or retracted in a generally longitudinal direction indicated in Figures 3 and 9 by a double arrow represented by reference numeral 58.
    [077] The comb with 26 spacing shown in Figure 8 is in a retracted state. Figure 9 illustrates a retracted state and an extended state of the movable comb portion 40 of the spaced comb 26. A respective extended state of the movable comb portion 40' is indicated in Fig. 9 by dashed lines. As can be seen in Figure 8, the user can actuate the sensor element 64 in a basically longitudinal direction 70, 72 to make an adjustment movement of the comb with spacing 26. By actuating or operating the sensor element 64, the user can control the adjustment drive for the comb with adjustable spacing 26 in order to set or establish a desired cut length.
    [078] Obviously, the exemplary configurations of the adjustment trigger 50 illustrated in Figures 3 to 9, specifically of the sensing elements 64 and the feedback units 74 thereof, are provided essentially for the purpose of illustration. Consequently, the respective modalities should not be interpreted in a limiting sense.
    [079] Still referring to Figure 10, an exemplary method of operating a comb with adjustable spacing for an apparatus for hair cutting is illustrated and further described. The method may comprise a step S10 which may involve providing an adjustment driver comprising an actuator for driving a movable comb portion of an adjustable spacing comb of a hair trimming apparatus. Preferably, the adjustment trigger is formatted in accordance with at least some of the embodiments presented in the present invention. Thereafter, an additional step S12 may take place which may involve the provision of a sensor element. The sensing element can be arranged as a proximity-sensitive or touch-sensitive user action interface, particularly a gesture control interface. An additional step S14 can then take place which may involve the detection of multifaceted user actions applied to the sensing element. Multifaceted user actions can involve touches, gestures, etc. In a subsequent step S16, based on detected user-entered data, a respective user action signal can be generated and provided for further processing. Preferably, the user action signal indicates at least the input speed. In addition, the user action signal can be indicative of input direction, input amplitude, and additional input values that can be derived from the signal. In yet another step S18, the actuator of the tuning trigger can be operated based on the user's action signal. Step S18 may involve converting the user action signal into an actuator operating signal. For this purpose a control unit can be provided. In case the user action basically consists of an input touch, the actuator operating signal may depend on the input touch speed, input touch direction and input touch amplitude detected.
    [080] Figure 11 illustrates several substeps of an embodiment of a method for operating a comb with adjustable spacing according to the present disclosure. Particularly, the detection of an input from touches applied to the sensitive surface of the sensing element is addressed. A step S20 may involve detecting touch on the sensing element. Consequently, a multifaceted user action signal can be detected by a control unit. The user action signal can include information related to various aspects of the input touch.
    [081] The user action signal can be analyzed and processed accordingly. By way of example, the method can comprise optional substeps that can be implemented as optional steps or in combination. The substeps may comprise a step S22 which involves deriving an input stroke direction from the input signal. Consequently, it can be evaluated whether the user wishes to extend or retract the movable comb portion. The substeps may further comprise a step S24 which involves deriving an input ring speed from the input signal. Consequently, it can be judged whether the user wants to operate the moving comb portion at high or low speed to cover large or small adjustment distances. The substeps may further comprise a step S26 which involves deriving an input ring amplitude from the input signal. Consequently, conclusions about the desired qualitative and/or quantitative length-fit values can be drawn from the input stroke amplitude. A subsequent step S28 may involve generating an output signal in case data obtained in any one of the (sub)steps S22, S24 and S26 is considered. Based on the output signal, the trim trigger and therefore the adjustable spacing comb can be operated to set the desired cut length.

A single element or another unit can perform the functions of several items mentioned in the claims. The mere fact that certain measures are mentioned in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
