Abstract:
An improved electrode for use in displays, including those of the touchscreen type, has a conductive polymeric material disposed over the electrode material at those regions where the electrode is subject to flexing in use, thereby putting the electrode material at risk of cracking. The conductive polymeric material bridges any cracks which may develop, thus providing electrical continuity.
Abstract:
A uniformly luminous EL sheet diaphragm and a lighted switch which is of a thin structure, provided with the EL sheet diaphragm, and used in input operating sections of various kinds of electronic devices are disclosed. A diffusion EL sheet comprises a transparent electrode (4) formed on a transparent film (3), a light emitting layer (5), a dielectric layer (6), a rear electrode layer (7) and an insulating layer (8). The EL sheet is formed so that the light emitting side is convex, thus fabricating a diaphragm part (2). A thin switch is produced by forming an electrode contact layer (9) on the insulating layer (8) on the concave side of the diaphragm (2) and an opposed electrode contact layer (11) on an insulating film base (10) opposing the layer (9). The tranparent electrode layer (4) is formed by printing and drying paste prepared by dispersing conductive powder having a visible light transmittance in an insulating resin. A high dielectric constant and flexible resin selected from vinylidene fluoride rubber, and a resin prepared by blending cyanated pullulan or cyanated cellulose and cyanated polyvinyl alcohol is used as the binder resin for the light emitting layer (5) and the dielectric layer (6). Therefore light emission failure due to wire disconnection in the diaphragm part (2) is prevented, providing a high quality EL sheet diaphragm and a switch using the diaphragm.
Abstract:
Keyboard for the control box (11) of an electric apparatus comprising a sheet (1) which forms a plurality of contactors (2) each projecting from the sheet through a blister (3) which is elastically deformable and which acts as a spring, said contactors (2) being provided with bearing keys (8) and contact pads (5) intended to come into contact with a printed circuit (12) arranged under the sheet (1) of contactors when a pressure is exerted on the keys. This keyboard is remarkable in that at least certain of said contactors (2) are provided with stubs (4) arranged opposite the contact pads (5) and which are intended to be force nested into corresponding housings provided in the bearing keys (8).

A hearing assistance device (100), comprising a microphone (101) to receive sound, signal processing electronics electrically connected to the microphone, a receiver electrically connected to the signal processing electronics and a switch (102) electrically connected to the signal processing electronics. The switch (102) includes conductive silicone (106) adapted to change the switch from a first state to a second state when activated. Contacts comprising conductive silicone (105) provide an electrical connection between the microphone (101) and the signal processing electronics.
Abstract:
Beschrieben wird ein Kontaktelement (7) zur intermittierenden Kontaktierung von Leiterbahnen (2, 3) auf einer Leiterplatte, insbesondere für flexible Schaltmatten (4-6), beispielsweise für flexible Eingabegeräte aus dem Automobilbereich. Eine sehr zuverlässige und insbesondere auch für hohe Ströme respektive hohe Spannungen geeignete Konstruktion wird dadurch erreicht, dass das Kontaktelement aus einem Metallschwamm (8) besteht. Der Metallschwamm ist dabei bevorzugtermassen wenigstens teilweise von einem elastomeren Material, welches gleichzeitig das Baumaterial der Schaltmatte sein kann, durchdrungen. Weiterhin wird ein Verfahren zur Herstellung eines solchen Kontaktelementes respektive von Schaltmatten/Eingabegeräten mit solchen Kontaktpillen sowie die Verwendung von solchen Kontaktpillen (7) beschrieben.
Abstract:
A pointing device may be directly soldered to a printed circuit board. In one embodiment, a bottom substrate defines a sensing region with a plurality of interdigitated conductive trace regions. Each trace region includes interdigitated common and sense traces. At least one via passes through the bottom substrate for each trace. Each via supports a conductive path from one trace to at least one lead element. Each lead element is solderable to a printed circuit board. A flexible substrate is constructed from a heat resistant polymer. The flexible substrate has a resistive layer deposited on a bottom side. A raised pedestal is formed on the bottom substrate top face around at least a portion of the sensing region. The pedestal separates the interdigitated conductive traces from the flexible substrate resistive layer. A button on a keypad membrane may be used to depress the flexible substrate onto the trace region.
