CROSS REFERENCE TO RELATED ORDERS
[001] This application claims priority from Provisional Patent Application US 61/681,010, filed August 8, 2012. Priority of the provisional patent application is expressly claimed and the disclosure of the provisional patent application is hereby incorporated herein by reference. in its entirety and for all purposes. APPLICATION FIELD
[002] The disclosed modalities generally refer to impact safety and, more particularly, but not exclusively, to translucent panels with one or more frangible regions to allow the translucent material to fail in a predictable manner after being impacted. FUNDAMENTALS OF THE INVENTION
[003] Vehicles, such as automobiles and aircraft, generally include regions within the passenger cabin that include glass panels. Glass panels, for example, can be associated with a windshield or vehicle window.
[004] If equipped with passenger entertainment systems, vehicles often include video monitors to display information and otherwise entertain passengers while traveling. For various reasons, it is desirable that these monitors include a front cover made of glass. Glass, however, can shatter, shattering into dangerous shards when hit. The glass can be hit by a passenger's head or other end, injuring the passenger, if the vehicle suddenly decelerates or swerves during the journey or if an emergency situation arises. In addition to the potential for passenger injury, broken glass is also difficult and dangerous for cleaning crews to remove.
[005] Conventional video monitors typically have a front cover that is made of glass. These front covers do not safely and predictably fail during Head Injury Criteria non-lethality tests as defined by the Federal Aviation Administration. That is, either shards of glass or the entire glass cover fall into the passenger cabin during these tests. Recognizing the convenience of incorporating video monitors with a glass front cover, airlines and their suppliers have tried unsuccessfully for years to create a glass front cover that fails safely and predictably.
[006] In view of the foregoing, there is a need for a system and method to provide a translucent material and assembly that promotes impact safety in transport and other operating environments.

[007] Note that the figures are not drawn to scale and that elements of similar structures or functions are generally represented by similar reference numerals for illustrative purposes in all figures. It should also be noted that the figures are only intended to facilitate the description of preferred embodiments. The figures do not illustrate all aspects of the described modalities and do not limit the scope of this disclosure. DETAILED DESCRIPTION OF PREFERRED MODALITIES
[008] Since currently available video monitors include a glass front cover that, when hit, can shatter and break into dangerous shards, a translucent panel that breaks in a predictable manner may prove desirable and provide a foundation for a wide range of applications such as front covers for video monitors used on board vehicles such as automobiles and aircraft, as well as for use in portable or home/office devices such as smart phones, tablets and televisions. This result can be achieved, in accordance with an embodiment disclosed herein, by a panel 100, as illustrated in Fig. 1.
[009] Returning to Fig. 1, panel 100 is illustrated as comprising a panel surface 110 having a frangible region 120. The frangible region 120 is preferably indistinguishable from the remainder 121 of the panel surface 110 during normal conditions, but is adapted to allow panel 100 to break in a safe and predictable manner when a predetermined amount of force is applied to frangible region 120. Stated somewhat differently, panel 100, when struck, does not splinter and/or form sharp shards that can hurt people nearby. Instead, frangible region 120 may rupture from the remainder 121 of panel 100, preferably as an intact unit with no internal fracturing. In this way, the risk of personal injury can be minimized. Advantageously, the lack of sharp shards can similarly facilitate the cleaning and/or replacement of the broken panel 100.
[010] The frangible region 120, like the panel 100 itself, can be formed from any conventional material and can be supplied in any size, thickness, dimension and/or appropriate geometry. As illustrated in Fig. 1, for example, panel 100 may be formed as a rectangular panel with a rounded frangible region 120. While illustrated as comprising a central region of panel surface 110 for purposes of illustration only, frangible region 120 may be provided on any suitable area of panel surface 110. In one embodiment, panel surface 110 may include a plurality of frangible regions 120 each being provided as defined above.
[011] Fig. 2A illustrates an exemplary sectional side view of panel 100 with a boundary 122 separating a frangible region 120 from the remainder 122. Returning to Fig. 2B, upon application of a force (F) on a panel surface 110 of frangible region 120 of panel 100, boundary 122 disintegrates allowing frangible region 120 to break away from remainder 121 of panel 100. Following the application of force (F), as illustrated in Fig. 2B, frangible region 120 is intact and detached from the remainder 121 of panel 100 as illustrated in Fig. 2
[012] Fig. 3A is similar to Fig. 2A, except that a boundary 122 of Fig. 3A is shown as having a non-zero width. Returning to Fig. 3B, upon application of a force (F) to a panel surface 110 of a frangible region 120 of a panel 100, a boundary region 122 disintegrates, allowing the frangible region 120 to break away from the remainder 121 of the panel. 100. Following the application of a force (F), as shown in Fig. 3B, the frangible region 120 is intact and detached from the remainder 121 of panel 100 as shown in Fig. 3C.
[013] Fig. 4A is identical to Fig. 3A. However, going back to Fig. 4B, upon applying a force (F) to a panel surface 110 of a frangible region 120 of a panel 100, a boundary region 122 disintegrates into a chip 123, allowing the frangible region to 120 breaks away from a remainder 121 of panel 100. Following the application of force (F), as shown in Fig. 4B, frangible region 120 is intact and detached from remainder 121 of panel 100, as illustrated in Fig. 4. How also illustrated in Fig. 4C, the dispersion of the chip 123 is not controlled.
[014] Fig. 5A is identical to Fig. 4A, except that a film 230 is applied to a panel surface 110 of a panel 100. The film 230 may comprise one or more layers and may be disposed on the panel surface 110 through any conventional way. Returning to Fig. 5B, upon applying a force (F) to a panel surface 110 of a frangible region 120 of a panel 100, a boundary region 122 disintegrates into a splinter 123, allowing the frangible region 120 to break apart. a remainder 121 of the panel 100 and stretching the film 230 around a region of film 231. Following the application of force (F), as illustrated in Fig. 5B, the frangible region 120 is intact and detached from the remainder 121 of the panel 100 as illustrated in Fig. 5C. As also illustrated in Fig. 5, the dispersion of the splinter 123 was controlled by the film 230 which tore to form a film end 232.
[015] Returning to Fig. 6, a panel 100 can. be advantageously incorporated into a frangible panel assembly 200 which further promotes the panel 100 to break safely and predictably when a predetermined amount of force is applied to a frangible region 120 of the panel 100. One embodiment of the frangible panel assembly 200 includes a housing 210 with a wall 212. The panel 100 is coupled to an inner surface 211 of the housing 210. The inner surface 211 of the housing 210 forms (and/or defines) a chamber 221 that can be partially closed. Panel 100 may be coupled to inner surface 211 of housing 210 in any conventional manner, such as with an adhesive, fasteners, retainers, or applied force (e.g., magnets, suction cups, or friction). The term "retainers" refers to any combination of mating elements, such as blocks, flaps, pockets, slots, ramps, locking pins, cantilever elements, support pins and the like, which can be selectively or automatically engaged and/or disengaged to couple or uncouple panel 100 and housing 210 to each other.
[016] An alternative embodiment of a frangible panel assembly 200 is shown in Fig. 7A. Turning to Fig. 7A, frangible panel assembly 200 includes a housing 210 with a wall 212. Panel 100 is coupled to an inner surface 211 of housing 210 in any conventional manner, as noted above. Compared to chamber 221 of Fig. 6, inner surface 211 of housing 210 forms an extended-height chamber 221 that can also be partially closed. Returning to Fig. 7B, upon sufficient impact, panel 100 can fail in a predictable manner, allowing frangible region 120 to break away from remainder 121 of panel 100 and recede into chamber 221.
[017] Unlike the prior art translucent panels that when hit shatter and/or form sharp shards that can injure people in the vicinity, the frangible region 120 can break from the panel 100, preferably as an intact unit without internal fracturing. In fact, a dashboard displaying both translucency and safety-on-impact is unexpected and addresses a long felt need, particularly in the aviation industry for video monitors.
[018] Turning to Fig. 8A, another embodiment of a frangible panel assembly 200 includes a panel 100 with a frangible region 120 and a housing 210 with a wall 212. Here, the housing 210 may include a first housing element 210A and a second element of: housing 210B. The first housing element 221A has a wall 212 with a first inner surface 211A forming (and/or defining) a first chamber 221A with an opening 214 and which is otherwise partially closed. Panel 100 is coupled to the first inner surface 211A of the first housing element through any conventional manner, as mentioned above, closing opening 214. Second housing member 210B has a wall 212 with a second inner surface 211B. The second inner surface 211B of the second housing element 210B forms (and/or defines) a second chamber 221B which can also be partially closed. As indicated in Fig. 8A, the first housing element 210A and the second housing element 210B can be coupled through any conventional way, such as with an adhesive, fasteners, retainers or applied force (e.g. magnets, suction cups or friction). The term "retainers" refers to any combination of combination elements, such as blocks, flaps, pockets, slots, ramps, locking pins, cantilever elements, support pins and the like, which can be selectively or automatically engaged and /or disengaged to couple or uncouple the first housing element 210A and the second housing element 210B with respect to each other.
[019] Returning to Fig. 8B, the first housing element 210A and the second housing element 210B are coupled together so that the first inner surface 211A and the second inner surface 211B align to form an inner surface 211 that defines (and/or form) a chamber 221 that fuses the first section 221A and the second chamber 221B.
[020] Turning to Fig. 9A, a portion of a housing 210 of another embodiment of a frangible panel assembly 200 is shown separated from a panel 100 for clarity. As shown in Fig. 9A; panel 100 has a panel surface 110 and further includes a boundary 122 separating a frangible region 120 from a remainder 122. Housing 210 has a wall 212 and an inner surface 211 defining (and/or shaping) a chamber 221 that may be partially closed. Housing 210 further includes a selected wall 212A with an inner surface 211 and an opposing wall 212B with an inner surface 211. Both the selected wall 212A and the opposing wall 212B each connect to a face wall 212C. Face wall 212C forms an opening 214 in housing 212. As shown in Fig. 9A, housing 210 is configured so that panel surface 110 of panel 100 can be coupled to inner surface 211 of face wall 212C of panel. housing 210 through any conventional manner as mentioned above, thereby closing opening 214.
[021] Turning to Fig. 9B, panel 100 is shown as being coupled to inner surface 211 of face wall 212C of housing 210, thereby closing opening 214. Specifically, a portion of: panel surface 110 covering the The remainder 121 of panel 100 is coupled to a portion of inner surface 211 of face wall 212. Upon application of a force (F) to a panel surface 110 of frangible region 120 of panel 100, boundary 122 disintegrates, allowing the frangible region 120 breaks away from the remainder 121 of panel 100, as shown in Fig. 9C. Following the application of force (F), as shown in Fig. 9C, the frangible region 120 retreats into chamber 221 and is intact and detached from the remainder 121 of panel 100 as shown in Fig. 9C. Thus, unlike conventional systems, frangible region 120 can rupture from panel 100, preferably as an intact unit with no internal fracturing, and safely recede into chamber 221.

[026] Returning to Fig. 12A, a portion of a housing 210 of another embodiment of a frangible panel assembly 200 is again shown separated from a panel 100 for clarity. As shown in Fig. 12A, panel 100 has a concave shape that forms a surface of panel 110. Panel 100 further includes a boundary 122 separating a frangible region 120 from a remainder 122. Housing 210 has a wall 212 and an inner surface 211 which defines (and/or forms) a partially closed chamber 221. Housing 210 further includes a selected wall 212A with an inner surface 211 and an opposing wall 212B with an inner surface 211. Both the selected wall 212A and the opposing wall 212B each connect to a face wall 212C. The face wall forms an opening 214 in housing 212 with an opening surface 211 surrounding opening 214. As shown in Fig. 12A, housing 210 is configured so that panel surface 110 of panel 100 can be coupled to the surface. internal 211 and to the opening surface 211A of the face wall 212C of the housing 210, thereby closing the opening 214.
[027] Turning to Fig. 12B, panel 100 is shown as being coupled to inner surface 211 and opening surface 211A of face wall 212C of housing 210, thereby closing opening 214. Specifically, a portion of the surface of panel 110 covering the remainder 121 of panel 100 is coupled to inner surface 211 of face wall 212. In addition, an end surface 110B of panel 100 is also shown as being coupled to inner surface 211 of selected wall 212A and the opposite wall. 212B.
[028] Turning to Fig. 13A, a portion of a housing 210 of another embodiment of a frangible panel assembly 200 is shown separated from a panel 100 for clarity. Panel 100 has a panel surface 110 and further includes a boundary 122 separating a frangible region 120 from a remainder 122. A film 230 is applied to a panel surface 110 of a panel 100. The film 230 may comprise one or more layers and may be disposed on panel surface 110 in any conventional manner. Housing 210 has a wall 212 and an inner surface 211 that defines (and/or forms) a partially closed chamber 221. Housing 210 further includes a selected wall 212A with an inner surface 211 and an opposing wall 212B with an inner surface 211. Both the selected wall 212A and the opposing wall 212B each connect to a face wall 212C. The face wall forms an opening 214 in housing 212. As indicated in Fig. 13A, housing 210 is configured so that panel surface 110 of panel 100 can be coupled to inner surface 211 of selected wall 212A and the opposite wall. 212B from housing 210 through any conventional manner, as mentioned above, thereby closing opening 214.
[029] Returning to Fig. 13B, panel 100 is shown as being coupled to inner surface 211 of selected wall 212A and opposite wall 212B of housing 210, thereby closing opening 214. Specifically, an end surface 110B of panel 100 is shown as being coupled to inner surface 211 of selected wall 212A and opposite wall 212B. Furthermore, a portion of film 230 covering the remainder 121 of panel 100 is coupled to inner surface 211 of face wall 212C. As will be discussed further, coupling film 230 to inner surface 211 of face wall 212C can prevent delamination of film 230 from panel 100.
[030] Upon application of a force (F) on a panel surface 110 of the frangible region 120 of the panel 100, the boundary 122 disintegrates into a splinter 123, allowing the frangible region 120 to break away from the remainder 121 of the panel 100 and stretch the film 230 around a region of film 231 as shown in Fig. 13C. As mentioned above, coupling the film 230 to the inner surface 211 of the face wall 212C can prevent the delamination of the film 230 from the panel 100. Following the application of force (F), as illustrated in Fig. 13, the frangible region 120 backs off into chamber 221 and is intact and detached from the remainder of 121 of panel 100 as illustrated in Fig. 13D. As also illustrated in Fig. 13D, the dispersion of the splinter 123 was controlled by the film 230 which tore away, forming a film edge 232. In fact, the splinter 123 safely retreats into the chamber 221.
[031] Unlike prior art translucent panel housings that when hit the panel shatters or forms sharp shards that can injure people in the vicinity, the frangible region 120 may rupture from panel 100, preferably as an intact unit without internal fracturing and securely retreating to chamber 221. In addition, film 230 controls the dispersion of splinter 123, which also securely retreats to chamber 221. A translucent panel housing with the aforementioned impact safety features is unexpected and it addresses a long-felt need, particularly in the aviation industry's video monitors.

Panel 100 may be coupled to inner surface 211 of housing 210 through any conventional form, such as with adhesive, fasteners, retainers, or applied force (eg, magnets, suction cups, or friction). The term "retainers" refers to any combination of combination elements, such as blocks, flaps, pockets, slots, ramps, locking pins, cantilever elements, support pins and the like, which can be selectively or automatically engaged and /or disengaged to couple or uncouple panel 100 and housing 210 to each other. In addition, panel surface 110 is shown as being flush with face surface 211A of face wall 212C of housing 210. The entire housing 210 is shown in Fig. 14C.

In addition, mounting surface 110 is shown as being coextensive with face surface 211A of face wall 212C of housing 210.
[038] Turning to Fig. 17A, a portion of a housing 210 of another embodiment of a frangible panel assembly 200 is shown separated from a panel 100 for clarity. As shown in Fig. 17A, panel 100 is identical to panel 100 shown in Fig. 16A, except for a boundary 122 with an alternative placement closer to a region of panel 140. Likewise, a housing 210 is identical to the housing 210 shown in Fig. 16A. Returning to Fig. 17B, a frangible panel assembly 200 is shown to be identical to the frangible panel assembly 200 of Fig. 16B, except for the alternative placement of boundary 122 of panel 100 as described in relation to Fig. 17A
[039] An alternative embodiment of the panel 100 of Fig. 1 is shown in Fig. 18A. While panel 100 may be formed of any conventional panel material, including opaque panel materials, panel 100, in this embodiment, advantageously may be formed of a rigid, transparent material such as glass or polycarbonate. Turning to Fig. 18A, panel 100 is illustrated as being formed with predetermined dimensions and having at least one frangible region 120 disposed therein. Panel 100 of Fig. 18A is illustrated as having five frangible regions 120A-E each having a selected shape, size and/or location. The 120A-E frangible regions are shown as having different shapes, sizes and locations for illustration purposes only. As desired, a selected frangible region 120 may be provided with a selected dimension and/or geometry and may overlap another frangible region 120. As illustrated in Fig. 18A, a first frangible region 120A' partially overlaps a second frangible region 120C ', thereby defining and/or delimiting the three frangible regions 120A-C. As further illustrated in Fig. 18A, frangible region 120D concentrically overlaps frangible region 120E. Advantageously, the frangible regions 120A-E each allow the panel 100 to rupture in a predetermined fashion if impacted with sufficient force. For example, the frangible region 120E allows the remainder of the panel 100 to remain intact if the panel 100 is impacted with sufficient force only on the frangible region 120E.
[040] The frangible region 120 can be defined and/or delimited by any conventional shape. In one embodiment, for example, selected frangible region 120 may be defined and/or delimited by a notch 111 that forms a boundary 122 between frangible region 120 and a remainder 121, as illustrated in Fig. 18B. Turning to Fig. 18B, notch 111 is shown as being formed in a continuous or contiguous pattern within a perimeter region 113 of panel 100. Although shown as having an outline that conforms to an outline 116 of panel 100 for purposes of illustration only, slot 111 can be provided with any conventional geometry.
[041] Additionally and/or alternatively, the frangible region 120 may be defined and/or delimited by a locally limited stress gradient region 114 that forms a boundary 122 between the frangible region 120 and a remainder 121, as illustrated in Fig. 18C. The locally constrained stress gradient region 114 may be a region of panel 100 with an inhomogeneous stress state. Returning to Fig. 18, locally constrained stress gradient 114 is shown as being formed in a continuous pattern within perimeter region 113 of panel 100. Although shown as having an outline that conforms to outline 116 of panel 100 for purposes for illustration only, locally limited stress gradient 114 can be provided with any conventional geometry.
[042] Figs. 19A-C illustrate exemplary sectional side views of panel 100 with notch 111. Although notch 111 is shown as being alternatively semicircular, triangular, and rectangular in these figures for illustration purposes, notch 111 may be formed with any cross-sectional geometry. conventional. The depth and width of the notch 111 may vary and may comprise any suitable value. In one embodiment, notch 111 may have a depth of up to approximately 0.1 mm or more and/or a width of up to approximately 0.87 mm or more.
[043] As desired, the depth and width of notch 111 can be independently set as a preselected percentage (and/or a preselected percentage range) of the maximum depth and width, respectively, of notch 111. pre-selected percentage specimens may include between fifty percent (50%) and one hundred percent (100%) of the maximum depth and/or width of notch 111, including any percentage subranges, such as a five percent (or that is, between sixty-five percent (65%) and seventy percent (70%) and/or a sub-range of ten percent (ie, between sixty percent (60%) and seventy percent (70%) ), within the pre-selected percentage range, without limitation. As set forth above, the set of numerical values cited throughout this descriptive report are for illustrative purposes only and not for purposes of limitation.
[044] Returning to Fig. 20, in an embodiment where panel 100 has curved surface regions 118A and 118B in compression and tension, respectively, it is preferable for notch 111 to be disposed in curved surface region in tension 118B. Panel 100 can be formed using any one or more conventional processes, such as Thermal Sheet Molding by GPlnnvation GmbH, Potsdam, Germany.
[045] Figs. 21A-F illustrate that panel 100 may include more than one notch 111 to define one or more selected frangible regions 120. Fig. 21A illustrates two notches 111A-B formed adjacent to opposite side regions 130 of panel 100; while, Fig. 21B illustrates two notches 111C-D formed adjacent to an upper region 132 and a lower region 134, respectively, of panel 100. Although the widths of notches 111A-D are shown to be more or less the same, the widths may vary between the different notches 111. Likewise, the depths of the notches 111 may vary between the different notches 111. Furthermore, the width and depth of a selected notch 111 may vary as desired. Fig. 21C illustrates a single notch 111 formed in a continuous pattern adjacent to a perimeter area 126 of panel 100. Fig. 21D illustrates two notches 111A-B formed adjacent to opposite side regions 130 of panel 100 and two notches 111C-D formed adjacent an upper region 132 and a lower region 134, respectively, of panel 100. Here, separate notches 111A-D form a composite notch 111M. Fig. 21 E shows a plurality of notches 111 EJ each formed adjacent a perimeter area 126 of panel 100 as well as a seventh notch 111K that is formed within a central area 136 of panel 100. Notches 111E-J are shown as being separated from each other by a gap region 112. The size of the gap region 112 may vary as desired and may even vary as between different pairs of notches 111. Fig. 21F shows an alternative embodiment of notches 111E-K of the Fig.8C. Here, the separate notches 111E-K form a composite notch 111 L. The arrangements of Figs. 21 E-F provide a pair of frangible regions 120 which can further decrease the likelihood that panel 100 will break into dangerous shards when hit.

[057] Fig. 24 shows an exemplary user seat assembly 400 that includes a video monitor assembly 300. While suitable for use in stationary operating environments such as buildings, the user seat assembly 400 can advantageously be installed for use in a passenger vehicle. In one embodiment, for example, user seat assembly 400 may be arranged aboard a conventional passenger aircraft, where video monitor assembly 300 may be provided as a part of an in-flight entertainment system, such as such as the Series 2000, 3000, eFX and/or eX2 in-flight entertainment systems manufactured by Panasonic Avionics Corporation (formerly known as Matsushita Avionics Systems Corporation) of Lake Forest, California. Although shown as being disposed on a backrest 410 of user seat assembly 400, video monitor assembly 300 may be disposed on any conventional region of user seat assembly 400, such as on an armrest 420. , video monitor assembly 300 may be provided as part of an instrument panel that displays flight information, such as altitude, as Global Positioning System (GPS) location information. The ability to securely incorporate a translucent panel, such as glass, as a video monitor front cover is unexpected and addresses a long felt need, particularly in the aviation industry. In fact, airlines and their suppliers have been trying unsuccessfully for years to create a glass front cover that fails safely and predictably.
[058] In one embodiment, the panel 100 of Fig. 1 is composed of glass and can be manufactured in accordance with the exemplary method 500, as illustrated in Figure 25. At 510, a sheet of glass can be formed using any conventional process , such as a floating glass process. Preferably, panel 100 comprises Corning® Gorilla® Glass. Corning® and Gorilla® are registered trademarks of Corning Inc., of Corning, NY. In making Corning Gorilla Glass, a melting method can be employed. For example, 510 may comprise 512, 514 and 516 as illustrated in Fig. 26A. At 512, a molten glass composition is prepared. At 514, a V-shaped gutter is overflowing with the molten glass composition. At 516, molten glass is allowed to flow evenly in both lateral regions of the trough and gather in the lower region to form a sheet of glass. Returning to Fig. 25, at 520, panels 100 can be cut from the glass sheet. Glass can be cut using conventional processes. Optionally, at 530, panel 100 can be molded using any one or more conventional processes, such as Thermal Sheet Molding by GPlnnvation GmbH, Potsdam, Germany. Also optionally, at 540, panel 100 can be finished using conventional processes. For example, sharp edges can be polished smooth.
[059] To form a boundary 122, one or more notches 111 can be formed in the panel 100 out of 550. To decrease its visibility, the notches 111 are preferably arranged only on one surface of the glass panel 100. The glass can be engraved using any one or more conventional techniques, such as laser cutting, grinding, pickling and/or milling. The depth and width of a selected notch 111 each may vary and may comprise any suitable dimension. Likewise, the depth and width of the notches 111 may vary between the different notches 111. In one embodiment, the notch 111 may have a depth of up to approximately 0.1 mm or more and/or a width of up to approximately 0.1 mm. 87 mm or more, where panel 100 may have a thickness of up to approximately 1.1 mm or more.
[060] As desired, the depth and width of the notch 111 can be independently set as a preselected percentage (and/or a preselected percentage range) of the maximum depth and width, respectively, of the notch 111. Preselected percentage ranges selected specimens may include between fifty percent (50%) and one hundred percent (100%) of the depth and/or maximum width of the notch 111, including any percentage subranges, such as a five percent subrange (ie, between sixty-five percent (65%) and seventy percent (70%)) and/or a sub-range of ten percent (ie, between sixty percent (60%) and seventy percent (70%)), within the pre-selected percentage range, without limitation. As set forth above, the set of numerical values cited throughout this descriptive report are for illustrative purposes only and not for purposes of limitation.
[061] As set forth above with reference to Fig. 18C, the frangible region 120 may be defined and/or delimited by any conventional shape, including a locally limited stress gradient 114 that forms a boundary 122. A stress gradient locally limited 114 can be formed into a composite glass panel 100 in accordance with an exemplary method 600 as illustrated in Fig. 27A. Returning to Fig. 27A, at 610, panel 100 can be heated above the transformation temperature with a laser over a desired threshold 122. At 620, panel 100 can be rapidly cooled, thereby forming a voltage gradient locally constrained along the desired boundary 122. Alternatively, a locally constrained stress gradient 114 can be formed in a glass composite panel 100 in accordance with an exemplary method 604 as illustrated in Fig. 27B. Returning to Fig. 27B, a greenhouse enamel can be applied to the panel 100 at 640 along a desired boundary 122, where the greenhouse enamel has an expansion coefficient sufficiently different from the expansion coefficient of glass. Stove enamel can be applied using any conventional process, such as printing. At 650, the panel 100 and the applied kiln enamel can be heated. At 660, the panel 100 and applied kiln enamel can be cooled, thereby forming a locally limited stress gradient along the desired boundary 122.
[062] Turning to Fig. 25, method 500 is shown, at 560, as optionally further comprising hardening panel 100. In other words, a panel 100 may be formed from glass fabricated in accordance with method 500, and at 560, optionally can be hardened. Glass can be hardened using any one or more conventional processes, such as thermal hardening (eg tempered glass) or chemical/ion exchange hardening (eg Corning Gorilla Glass). As discussed in more detail above with reference to method 500 (shown in Fig. 25), panel 100 preferably comprises Corning Gorilla Glass. In making Corning Gorilla Glass, a chemical hardening method can be employed. For example, 560 may comprise 562 and 564 as illustrated in Fig. 268. At 562, a potassium salt bath may be heated to a maximum temperature equal to or greater than 400 degrees Celsius. At 564, panels 100 can be dipped into the heated potassium salt bath.
[063] As discussed in more detail above with reference to method 500 (shown in Fig. 25), panel 100 preferably comprises Corning Gorilla Glass. Turning to Fig. 28A, a panel 100 is shown that has completed at least steps 510 and 520 of method 500. In a preferred embodiment, panel 100 comprises glass that contains a plurality of sodium ions 116A. Returning to Fig. 28B, panel 100 has completed step 550 of method 500 and is shown with a notch 111. Returning to Fig. 28C, panel 100 is shown passing through step 564, as illustrated in Fig. 26C. Specifically, panel 100 is shown submerged in a heated potassium salt bath filled with a plurality of potassium ions 116B. During its submersion, the panel 100 goes through an ion exchange process. Specifically, sodium ions 116A migrate from a peripheral region 115 of panel 100 to the heated salt bath and are replaced by potassium ions 116B which migrate from the heated potassium salt bath to peripheral region 115 of panel 100. Although not shown in scale, sodium ions 116A are smaller than potassium ions 116B as indicated in Figs. 28C-D. Returning to Fig. 28D, panel 100 was removed from the heated potassium salt bath and the ion exchange process completed. Specifically, a compressed peripheral region 115 in panel 100 is formed where the larger 116B potassium ions have been replaced by the smaller 116A sodium ions. The compressed peripheral region 115 helps to inhibit fault formation and propagation in panel 100.

Fig. 30A illustrates an exemplary method 800A of assembling a video monitor assembly 300 comprising a cap assembly 900, a first housing member 210A, and a second housing element 210B. At 810, the first housing element 210A can be provided. At 820, the first housing element can be correctly positioned to be operated. At 830, cap assembly 900 may be assembled in accordance with exemplary method 700, as illustrated in Fig. 29. At 840, cap assembly 900 may be coupled to first housing member 210A in any conventional manner, such as such as adhesives, fasteners, retainers, or applied force (eg magnets, suction cups, or friction). The term "retainers" refers to any combination of combination elements, such as blocks, flaps, pockets, slots, ramps, locking pins, cantilever elements, support pins and the like, which can be selectively or automatically engaged and /or disengaged to couple or uncouple the cap assembly 900 and the first housing member 210A with respect to each other. At 850, the second housing element 210B can be provided. At 860, a video display 320 may be coupled to the second housing member 210B in any conventional manner, as mentioned above. At 870, first housing member 210A may be coupled to second housing member 210B in any conventional manner, as noted above.
[066] Fig. 30B illustrates an exemplary method 800A of assembling a video monitor assembly 300 comprising a cover assembly 900 and a housing 210. At 811, housing 210 may be provided. At 821, a video display 320 may be coupled to housing 210 via any conventional way, such as with an adhesive, fasteners, retainers, or applied force (e.g., magnets, suction cups, or friction). The term "retainers" refers to any combination of combination elements, such as blocks, flaps, pockets, slots, ramps, locking pins, cantilever elements, support pins and the like, which can be selectively or automatically engaged and/ or disengaged to engage or decouple the video display 320 and housing 210 with respect to one another. At 830, cap assembly 900 may be assembled in accordance with exemplary method 700, as illustrated in Fig. 29. At 841, cap assembly 900 may be coupled to housing 210 in any conventional manner, as noted above. .
[067] To help prevent tampering with a fire extinguisher, prior art fire extinguisher cabinets have employed tempered glass panels, which shatter into many small pieces when the panel is hit with sufficient force. It would be desirable and would address a long felt need to eliminate or substantially eliminate the mess and potential danger posed by small pieces of shattered tempered glass. Turning to Fig. 31A, a panel 100 may also be advantageously incorporated into a fire extinguisher cabinet assembly 1000. One embodiment of the fire extinguisher cabinet assembly 1000 includes a housing 210 with a wall 212. The inner surface 211 of housing 210 forms (and/or defines) a chamber 221 with an opening 214. Panel 100 is coupled with an inner surface 211 of a face wall 212C of housing 210, thereby closing opening 214. sized to house a fire extinguisher 1100. Panel 100 may be coupled to the inner surface 211 of housing 210 through any conventional manner, such as with an adhesive, fasteners, retainers, or applied force (e.g., magnets, suction cups, or friction ). The term "retainers" refers to any combination of combination elements, such as blocks, flaps, pockets, slots, ramps, locking pins, cantilever elements, support pins and the like, which can be selectively or automatically engaged and/ or disengaged to engage or decouple panel 100 and housing 210 relative to one another.
[068] Returning to Fig. 31B, upon sufficient impact, panel 100 can predictably fail, allowing a frangible region 120 to break from a remainder 121 of panel 100, preferably as an intact unit without internal fracturing and retreating into the chamber 221. Turning back to Fig. 31 C, a handle 215 can be attached to a panel surface 110 so that the frangible region can be safely removed from the chamber 221. A panel exhibiting both translucency and safety to impact is unexpected and addresses a long felt need of the fire extinguisher cabinet industry.
[069] Returning to Figs. 32A-C, a frangible panel assembly 200 may be advantageously incorporated into a switch assembly 1200 that incorporates into a door 1110 of a fire extinguisher cabinet assembly 1000. Turning to Fig. 32A, one embodiment of an assembly Extinguisher cabinet 1000 includes a housing 210 with a wall 212. The inner surface 211 of the housing 210 forms (and/or defines) a chamber 221 with an opening 214. A door 1110 can be coupled to the housing 210 through a hinge 1112 or any other conventional shape so that the door can open and close, thereby opening and closing the opening 214. As shown in Fig. 32A, the door 1110 is in a closed position. The chamber can be correctly sized to house a 1100 fire extinguisher. Coupling can be achieved through any conventional way, such as with an adhesive, fasteners, retainers or applied force (eg magnets, suction cups or friction). Returning to Fig. 32B, a front view of fire extinguisher cabinet assembly 1000 is shown with door 1100 closed. A handle 1111 can be attached to port 1110 through any conventional way to facilitate opening and closing of port 1110. Port 1110 may also include a switch assembly 1200 that can lock or unlock port 1110 in any conventional manner. , such as a lock. Returning to Fig. 32C, fire extinguisher cabinet assembly 1000 is shown with door 1110 in its open position with hinge 1112 clearly visible.
[070] In order to help prevent tampering with a fire extinguisher housed within a fire extinguisher cabinet assembly 1000, a frangible panel assembly 200 can be advantageously incorporated in the switch assembly 1200. Returning to Fig. 33A, a switch assembly 1200 is shown coupled to port 1110. Switch assembly 1200 may be coupled to port 1110 through any conventional manner, such as with an adhesive, fasteners, retainers, or applied force (e.g., magnets, suction cups or friction). The term "retainers" refers to any combination of combination elements, such as blocks, flaps, pockets, slots, ramps, locking pins, cantilever elements, support pins and the like, which can be selectively or automatically engaged and/or disengaged to couple or uncouple switch assembly 1200 and port 1110 with respect to each other. The switch assembly 1200 may include a frangible panel assembly 200 and a switch 1210. The switch may include a lever 1211 that functions to lock or unlock the door 1110. The frangible panel assembly 200 includes a panel 100 with a frangible region 120 and a housing 210 with a wall 212. The inner surface 211 of the housing 210 forms (and/or defines) a chamber 221 with an opening 214 and a rear opening 214A. A panel 100 is coupled with an inner surface 211 of a face wall 212C of housing 210 through any conventional manner as mentioned above, thereby closing opening 214. Switch 120 is positioned within rear opening 214A.
[071] Returning to Fig. 33B, upon sufficient impact, the panel 100 can fail in a predictable manner, allowing the frangible region 120 to break away from the remainder 121 of the panel 100, preferably as an intact unit without internal fracturing and recede into the chamber 221. Returning to Fig. 33C, lever 1211 is now safely accessible through opening 214. Lever 1211 can thus be squeezed, thereby unlocking door 1110.
[072] A similar need exists to help prevent tampering with fire alarm panels. Indeed, a frangible panel assembly 200 may be advantageously incorporated in a fire alarm cover assembly 1300. Returning to Fig. 34A, the fire alarm cover assembly 1300 may include a frangible panel assembly 200 and a 1310 fire alarm panel. The 1310 fire alarm panel includes a 1311 t-bar to activate an alarm. The frangible panel assembly 200 includes a panel 100 with a frangible region 120 and a housing 210 with a wall 212. The inner surface 211 of the housing 210 forms (and/or defines) a chamber 221 with an opening 214 and a rear opening 214A . A panel 100 is coupled with an inner surface 211 of a face wall 212C of housing 210, thereby closing opening 214. Fire alarm panel 1310 is positioned within rear opening 214A. Panel 100 can be coupled to housing 210 achieved in any conventional way, such as with an adhesive, fasteners, retainers or applied force (e.g., magnets, suction cups or friction). The term "retainers" refers to any combination of combination elements, such as blocks, flaps, pockets, slots, ramps, locking pins, cantilever elements, support pins and the like, which can be selectively or automatically engaged and/ or disengaged to engage or decouple panel 100 and housing 210 with respect to one another.
[073] Returning to Fig. 34B, upon sufficient impact, panel 100 can predictably fail, allowing frangible region 120 to rupture from a remainder 121 of panel 100, preferably as an intact unit without internal fracturing and retreat into the chamber 221. Fire alarm panel 1310 is now safely accessible through opening 214 and t-bar 1311 can thus be pulled down, thereby activating an alarm.
