    [0001] SURVEILLANCE SYSTEM. ALARM AND DETECTION THROUGH
    [0002]
    [0003] OBJECT OF THE INVENTION AND TECHNICAL SECTOR
    [0004]
    [0005] The present invention consists of a surveillance, remote alarm, location and detection system, for personal defense and security, aimed at people subject to a limitation of freedom of movement, preventing said people from approaching a certain minimum distance from a second person or zone, by activating an electric shock device.
    [0006]
    [0007] The invention is included within the alarm sector to guarantee the safety of people, more specifically in the sector of alarms that react to a single specified, undesirable or abnormal condition, and not provided for elsewhere.
    [0008]
    [0009] BACKGROUND OF THE INVENTION
    [0010]
    [0011] In recent years, the appearance of events related to people who were under restraining orders, house arrest, special surveillance or with semi-liberty permission, who have failed to comply with the conditions imposed by the law enforcement authorities, has caused the attention of public opinion is interested in existing electronic devices that allow knowing the location of these people as well as their detection in case of non-compliance with the established conditions.
    [0012]
    [0013] One of the main reasons for the development of such systems is generated by domestic and gender-based violence, being one of the main problems facing society. In this type of violence, women are most at risk in domestic or family settings, so many of them are harassed by their current or former partners.
    [0014]
    [0015] New technologies improve the fight against gender violence and domestic violence. For this reason, in recent years they have been developed and implemented systems in many countries that ensure that restraining orders are enforced, as well as electronic devices that monitor compliance with house arrests.
    [0016]
    [0017] In fact, there are various kinds of devices to track a person and ensure that they do not approach another person at a set minimum distance without their knowledge, as well as law enforcement. All of these devices operate using location technology and in some cases combine it with mobile telecommunications systems.
    [0018]
    [0019] These electronic location systems are known as wristbands, because they are put on the user's wrists or ankles, and are usually divided into geographic location systems, designed to determine the user's position wherever he may be and location systems. zone, which can reveal the presence of a user within or near a predetermined zone.
    [0020]
    [0021] The geographic location systems that these electronic systems use make use of a combination of GPS (satellite positioning system) and GSM (digital cellular telephone), which allows the precise determination of the geographical coordinates of a user, so that they can be transferred to an electronic map for immediate viewing.
    [0022]
    [0023] This technology provides very useful results, but they have limitations due to the failures produced in the location of people when they are in closed spaces such as large buildings, in addition to being susceptible to interference with other types of elements. Therefore, they are also combined with other more precise systems at shorter distances, such as radio frequencies, which are able to recognize if other devices are at a certain close distance.
    [0024]
    [0025] Thus, the most common systems used for the safety of persons with restraining orders normally consist of a cuff or bracelet that emits a radio frequency signal and one or two GPS and GSM tracking devices. The first user, obliged to be at a minimum distance from the second, must carry the bracelet on the wrist or ankle, and one of the devices, while the second user, the one who cannot be approached, carries the other device.
    [0026]
    [0027] Through location technology, the system determines the proximity between both users and verifies if there is any breach of the withdrawal measure. When the first user enters an exclusion area, if the second user gets closer than is allowed or some type of incident occurs, such as a loss of signal or the attempt to remove the bracelet, a signal is generated that is transmitted to law enforcement agencies so that they are notified and can contact the second user, to find out if it is okay, to warn them and to indicate that they adopt protective measures.
    [0028]
    [0029] However, the procedure is not always as fast as it should be and in the period from when the wristbands recognize the proximity between the users, until the police are alerted or go to the location of the possible victim, it can take a long time, enough for a violent confrontation to occur that can end irreparable damage.
    [0030]
    [0031] To this end, the present invention has been developed that prevents such damage from occurring to a possible victim, by making use of an alarm system that incorporates a paralyzing tool on the user who wears the remote wristbands.
    [0032]
    [0033] DESCRIPTION OF THE INVENTION
    [0034]
    [0035] Knowing the background described, the present invention has been designed to solve the drawbacks of the state of the art, offering a new device configured to warn, locate and stop in case of need to a user who should not approach a second user.
    [0036]
    [0037] In fact, the invention consists of an alarm, location and detection system for personal defense and security, which mainly comprises three bracelets, said bracelets being elements worn on the wrists or ankles and consisting of a strap and one detection module each.
    [0038] The first bracelet is configured to be attached to a first user by means of a removable connection from the strap, and comprises the first detection module, which in turn comprises a first location module, a first warning module, a first electric battery and some first charging means of said first electric battery. The electronic part of the bracelet has been called the detection module, that is, the electronic device of the bracelet.
    [0039]
    [0040] The second and third bracelet are configured to join a second user, also by means of straps, with a removable connection, based on an anti-manipulation and anti-extraction mechanism, so that said mechanism can only be removed by means of an opening Security not available for the second user, but for law enforcement.
    [0041]
    [0042] In one embodiment, at least one of the bracelets selected from the first, the second, and the third bracelet, are configured to be attached to a user's wrist, and to a user's ankle.
    [0043]
    [0044] Said second and third wristband each comprise a second detection module comprising a second location module, a second warning module, a second electric battery, a second means of charging said electric battery, and an electric discharge device with two electrodes.
    [0045]
    [0046] The system of the invention also comprises a receiving device comprising a control electronics that controls or manages a third detection module, a third location module and a third warning module.
    [0047]
    [0048] The invention is designed so that the first bracelet is worn by the first user who can be classified as a possible victim and so that the second and third bracelet are worn by the second user whom we will qualify as a possible aggressor, while the device reception is controlled by law enforcement.
    [0049]
    [0050] In this way, the first, the second and the third location module are configured to detect the position of the first and the second location module, that is, that both the first, the second and the third bracelet, as well as the receiving device they have controlled at all times the locations of the first, the second and the third bracelet.
    [0051]
    [0052] The second detection module, included in both the second and the third wristband, is configured to emit a signal, by means of the second warning module, when detecting, the second location module to the first location module, at a first predetermined distance , in the same way that the first detection module is also configured to emit a signal through the first warning module when detecting, the first location module to the second location module, at a first predetermined distance.
    [0053]
    [0054] In other words, when the bracelets are mutually detected, each one emits a signal that allows the first user to be alerted to the proximity of the second user, allowing them to flee or search for a safe space, while the second user lets them know that they are close to the first user, with the consequences that can be derived from it, and indicating that they should move away from their current position.
    [0055]
    [0056] The third detection module is also configured to emit a signal, by means of the third warning module, by detecting that the first and second location modules are at the first predetermined distance, so that the receiving device can be controlled by law enforcement and because of this can know if the second user is close to the first user, being alerted by it.
    [0057]
    [0058] In the event that the second user approaches even closer to the first user, the second detection module is configured to generate and emit an electric shock by means of electrodes of the discharge device, when the second location module detects the first location module at a second predetermined distance, this second distance being smaller than the first distance and sufficient so that the second user cannot approach the first user. This download temporarily paralyzes the second user, allowing the first user to escape or go to law enforcement while the second user is immobilized.
    [0059] In case the second distance is maintained, the second detection module is configured to generate and emit an electric shock up to a maximum of 4 times in periods of between 1 and 5 minutes.
    [0060]
    [0061] At the same time, the third detection module is configured to emit a signal through the third warning module, by detecting that the first and second location modules are at this second predetermined distance, which allows alerting the forces of the order of said situation.
    [0062]
    [0063] In one embodiment, the discharge device generates the electric discharge at a voltage between 200 and 2000 Volts, preferably between 400 and 1000 Volts, which is applied to the second user who wears at least the third or second bracelet, being immobilized upon receiving the download.
    [0064]
    [0065] In one embodiment, the discharge device generates the electric shock at 400 Volts, being applied to the second user who wears at least the second or third bracelet. A very high tension, depending on the intensity, the time and the physical characteristics of the user, can damage his health, and a lower tension may not affect him enough to become immobilized.
    [0066]
    [0067] In one embodiment, the discharge device generates the electric discharge during an interval of between 2 and 10 seconds, preferably between 5 and 6 seconds, to the second user who wears at least the second or third bracelet.
    [0068]
    [0069] In one embodiment, the discharge device delivers a discharge at an intensity of between 0.01 and 0.1 Amps, preferably 0.023 Amps.
    [0070]
    [0071] In one embodiment, the discharge device comprises coils connected to the electrodes that are configured to generate the electric discharge. This electrical discharge is generated by transforming the battery voltage and intensity comprising the detection module to voltage ranges between 200 and 2000 Volts, preferably 400 Volts, and at an intensity between 0.01 and 0.1 Amps. , preferably at 0.023 Amps.
    [0072] In one embodiment, the first, second, and third wristbands are connected to the receiving device via a mobile wireless network. This mobile wireless network connection can be selected from the group consisting of GSM, GPRS, EDGE, HSDPA, HSUPA, UMTS and WIFI network.
    [0073]
    [0074] This wireless connection allows the first bracelet to comprise, in one embodiment, a help button configured so that, when activated, the first detection module sends an alarm signal, via the mobile wireless network, to the third detection module of the detection device, thereby alerting law enforcement. This embodiment is an alternative so that, in the event that the first user considers himself to be in a dangerous situation, law enforcement officers can alert themselves and come to his aid knowing their exact location.
    [0075]
    [0076] In one embodiment, the first and second battery charging means of the wristbands are selected from the group consisting of a USB connector, a MicroUSB connector, and by induction.
    [0077]
    [0078] In one embodiment, the first, the second and the third warning module may be a vibrating element, a sound generator, a light generator, such as a "led" or a light bulb, and a combination thereof. In this way, both users and law enforcement agencies can be alerted through various different means that some of the previously configured distances have been exceeded.
    [0079]
    [0080] In one embodiment, the second detection module comprises at least one heart rate sensor, body temperature sensor, or both. Said sensor or sensors confirm that the second user wears the second and / or the third bracelet and that he does not try to take it off. These sensors are connected to the detection module, which since it is in communication with the other detection modules of the first bracelet and of the detection device via wireless network, both the first user and law enforcement officers can know if the first user has tried or succeeded in removing the second and / or third bracelet.
    [0081]
    [0082] In one embodiment, the first, second, and third location modules comprise a radio frequency, GPS, and GMS system.
    [0083] These location systems work in the way that the GPS provides the coordinates where each of the bracelets are located, the margin of error being less than 5 meters. If the GPS signal is lost, it automatically switches to a secondary tracking mode based on the GSM location. This type of location consists of identifying and locating a base station, that is, antennas that the mobile operator has distributed throughout the national geography, where the device is registered.
    [0084]
    [0085] The other mode of location is radio frequency (RF), based on the emission of a short-range signal from each of the bracelets, as well as the reception of said signal by devices that are within range. In this way, in case the first bracelet is close to the second and / or third bracelet, they recognize the radio frequency signals that each one emits and the separation distance between them can be determined.
    [0086]
    [0087] In addition to radio frequency, communication technologies such as infrared, ultrasound or Bluetooth can be used for indoor positioning.
    [0088]
    [0089] In one embodiment, the second and third bracelet comprise a mechanism with anti-tamper and anti-removal system.
    [0090]
    [0091] In one embodiment, the straps are made of carbon fiber and the electronic components are made of steel.
    [0092]
    [0093] In one embodiment, at least the second or third bracelet comprises an unlock or unlock device selected from the group comprising a fingerprint sensor, a key lock, or the input of an unlock code by a numerical combination.
    [0094]
    [0095] In one embodiment, the wristband detection modules are configured to connect wirelessly to a mobile device, such as a pocket or handheld computer. In this way, both the first and second users can know the status of the bracelets or the level of charge.
    [0096]
    [0097] BRIEF DESCRIPTION OF THE DRAWINGS
    [0098] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is included as an integral part of said description, where, by way of illustration and not limitation, it has been represented the next:

    [0101]

    [0105]
    [0106] PREFERRED DESCRIPTION OF THE INVENTION
    [0107]
    [0108] As can be seen in the figures, the invention consists of a surveillance system that comprises a series of devices of the type that law enforcement agencies use to ensure that an individual complies with a restraining order against a second individual or a specific location.
    [0109]
    [0110] As can be seen in figure 1, the surveillance system comprises a first bracelet (A) configured to be worn by a first user, who may be a possible victim, or left in a specific place such as a home or place of work of said first user, and as can be seen in figure 2, the system also comprises a second (B) and a third bracelet (C) configured to be worn by a second user, who may be a possible aggressor, that you should not approach the possible victim or said specific place or places.
    [0111]
    [0112] The first bracelet (A) comprises a strap (1a) of carbon fiber or plastic that is put around the wrist or ankle of the first user, and an electronics called the first detection module (2a), which comprises a first module for location (3a), a first warning module (4a), a first electric battery (5a) and a first charging means for said first electric battery (5a).
    [0113] This first detection module (2a) also comprises a heart rate and / or body temperature sensor (8) that allows determining whether said first bracelet (A) is worn by a user.
    [0114]
    [0115] On the other hand, the second (B) and the third bracelet (C) are identical. Both comprise a second carbon fiber strap (1b), due to the light and resistive characteristics of said material, attached to an ankle or wrist of a second user, so that it does not approach a certain distance from the first user.
    [0116]
    [0117] This second (B) and third (C) bracelets also comprise an electronics called the second detection module (2b), which comprises a second location module (3b), a second warning module (4b), a second electric battery (5b ), a second means for charging said electric battery (5b), and an electric discharge device (6) with two electrodes (7).
    [0118]
    [0119] Finally, the system also comprises a receiving device (D), which comprises control electronics consisting of a third detection module (2c), which comprises a third location module (3c) and a third warning module (4c), and a screen (12), configured to be used by law enforcement.
    [0120]
    [0121] The operation of the surveillance system consists in that, if the second user approaches a distance equal to or less than 250 meters from the first user, the location modules (3a, 3b and 3c) of the first (A), the second ( B) and the third bracelet (C), as well as that of the receiving device (D) detect it and the detection modules (2a, 2b and 2c) emit an acoustic and light signal so that both the first and second users and law enforcement is aware that the second user is at that distance from the first user. This allows the first user to be alerted, allowing them to go to a safe place, the second user to know that they must move away from their position, and law enforcement to know that an infraction has been committed.
    [0122]
    [0123] If the second user approaches a distance less than 25 meters from the first user, the location modules detect it, so that one of the second detection modules (2b), the second (B) or the third bracelet ( C) generate a electric discharge using the electric discharge device (6). This non-lethal electric shock (6) emitted by the second (B) or third bracelet (C) paralyzes the second user, giving the first user time to escape to a safe place, and giving the police time to go to the place where that second approach has occurred.
    [0124]
    [0125] The location modules (3a, 3b and 3c) use a system based on three different technologies, a radio frequency system for short distances, a GPS system for long distances and a GMS system for intermediate distances.
    [0126]
    [0127] In case the second distance is maintained, the second detection module (3b) is configured to generate and emit an electric shock (6) up to a maximum of 4 times in periods of between 1 and 5 minutes.
    [0128]
    [0129] It is therefore a non-lethal electric bracelet that launches interrupted electrical pulses, whenever the second user approaches a distance considered dangerous from the first user, which emit nerve signals from the brain, confusing the second user's motor muscles, mainly to the arms and legs, temporarily immobilizing the person.
    [0130]
    [0131] Its operation would be similar to a "taser" pistol, with the difference that a "taser" pistol throws electrodes that have to be shot by one user into the body of another user.
    [0132]
    [0133] This non-lethal electric shock (6) is generated at 400 Volts over a period of 5 to 6 seconds at an intensity of 0.023 Amps. Since the second (B) or third bracelet (C) are glued to the second user, power is not lost along the way, as is the case with the usual “taser” pistols.
    [0134]
    [0135] The discharge is carried out by means of two electrodes (7) connected to each of the electrical discharge devices (6), these being located in contact with the skin of the second user.
    [0136] As the wristbands of electronic mobile devices that comprise batteries are treated, in the event that the second batteries (5b) of the second or third wristbands (B or C) remain without charge, the second detection module (2b) detects and emits a signal through the second warning module (4b), advising the second user, two hours in advance, by means of small acoustic and light signals, which they must put on charge, so that if they do not do so half an hour before their discharge is total, the second detection module (2b) transmits this situation to the third detection module (2c).
    [0137]
    [0138] The reason why the second user has to wear two bracelets is because, since they are electronic devices that can be downloaded, the possible aggressor is prevented from approaching a possible victim during the download period, something that can happen in case of having only one of them.
    [0139]
    [0140] In this way, the second (B) and the third bracelet (C) are autonomous, and have a high charge autonomy so as not to require continuous charging, lasting at least 24 hours.
    [0141]
    [0142] The second (B) and the third bracelet (C) are communicated with each other so that, if the second bracelet (B) runs out of charge from the second electric battery (5b), automatically, the second bracelet (C) it is activated, and thus alternatively, the second user having to charge said second discharged electric battery (5b).
    [0143]
    [0144] This second user who wears the two bracelets (B and C), being able to wear them both on the ankles and on the wrists with a second strap (2b), cannot manipulate them with the intention of getting rid of them, since both comprise an anti-manipulation mechanism and anti-extraction (10) that only allows its opening by means of an unlocking device (11) consisting of a lock that can only be opened by a key that has the forces of order.
    [0145]
    [0146] If the second user tries to remove or manipulate the bracelets (B or C), the anti-manipulation and anti-extraction mechanism (10) detects it, sending a signal to the detection module (2b), sending an electric shock (6) to the second user leaving him stunned and immobilized, in turn sending a signal to the receiving device (D).
    [0147] To avoid that any of the second straps (1b) can be cut, they comprise a conductive element connected to the anti-tamper mechanism (10), so that if said conductive element is cut, the anti-tamper mechanism sends a signal to the device reception (D) through the detection module.
    [0148]
    [0149] This second detection module (2b) also comprises a heart rate sensor (8) and / or a body temperature sensor (8) that allows determining whether said second (B) or third bracelet (C) is worn by the second user.
    [0150]
    [0151] All the wristbands (A, B and C) are communicated via a mobile wireless network with the receiving device (D), which allows communication between the different detection modules (2a, 2b and 2c).
    [0152]
    [0153] On the other hand, the first bracelet (A) comprises an aid button (9) configured so that the first detection module (2a) sends a signal, through the mobile wireless network, to the third detection module (2c) of the detection (D).
    [0154]
    [0155] As is understandable, the system may comprise more than one first bracelet (A), so that the second user cannot approach more than a possible second user or more than a specific place.
