| 141 | Touch selection pad and method of manufacture | US40239 | 1987-04-20 | US4731694A | 1988-03-15 | Gunther Grabner; Dietrich Stephani |
| A touch selection pad contains a matrix of tactile sensors each of which contains a composite material with a pressure and direction-dependent electric conductivity and a dielectric material forming a capacitor. These are provided with column electrodes and row electrodes. When touched, each of the sensors creates a series circuit comprising a resistor formed of the composite material and a capacitor formed from the dielectric having a capacitance of preferably at least 50 pF. In this matrix of tactile sensors, the pressure-dependent resistance together with the associated fixed capacity serves as the measuring variable. The touch pad due to the small spacing between the sensors has a high resolution. It can be produced in a simple manner by sequentially depositing layers on a metalized carrier by means of a thin-film technique. The row and column electrodes can be etched out of a metalized plastic cover layer and a metalized carrier, respectively, by micro structuring techniques. | ||||||

| 145 | Keyboard switch assembly | US616363 | 1984-06-01 | US4524249A | 1985-06-18 | Charles F. Farrell |
| A keyboard assembly is shown utilizing a keypad formed from a sheet of soft rubber having a plurality of dome shaped portions. A conductive layer is disposed on the bottom surface of each dome shaped portion and is aligned with spaced interdigited conductive runs on a substrate at a switching station and is adapted to move into and out of bridging electrical contact with the spaced interdigitated runs. The keypad is compressed around the switching stations to form an environmental seal by ribs formed on an escutcheon and held there by posts projecting from the escutcheon through the keypad and substrate and deformed against the substrate. The substrate may be a flexible membrane supported by a rigid plate or it may be a circuit board type member. The dome shaped portions are integrally vented by a channel formed in the keypad extending between the dome shaped portions. | ||||||
| 146 | Planar touch panel | US449048 | 1982-12-13 | US4467151A | 1984-08-21 | Robert J. Johnson; Charles N. Miller; G. Patrick Bonnie |
| An electrical switch comprising a touch panel includes a flexible membrane having a series of parallel, electrically conductive strips formed thereon; and an opposed substrate layer having conductive strips thereon parallel and orthogonal to the membrane strips. A series of filament spacers, running parallel to the substrate layer strips, are positioned between the membrane and substrate layer to maintain the membrane strips and substrate strips in spaced-apart relation to each other. The filament spacers are secured to an associated boundary or frame. Finger or instrument pressure selectively applied to the membrane and directed toward the substrate, can establish contact between a chosen membrane strip and substrate strip to close the switch. The elastic deformation of the filament spacers enhances contact closure and contact life expectancy. The presence of insulative dust, which interferes with the current flow between the contacts, is eliminated. | ||||||

| 149 | Membrane keyboard switch assembly having selectable tactile properties | US187904 | 1980-09-17 | US4362911A | 1982-12-07 | Ronald J. Sears; Jack R. Gross |
| A "membrane"-type keyboard includes a resilient foam layer having an array of holes therein with the layer being sandwiched between first and second flexible membranes having electrical conductors thereon which are arranged to complete a circuit associated with a hole when the first and second membranes are moved toward each other. Embodiments including dome-shaped areas in the first flexible membranes provide for "tactile feedback" and additional foam layers enhance the operating characteristics of the embodiments. The method generally entails determining the operating parameters of a desired keyboard and simply changing the relative density and/or thicknesses of various layers and flexible membranes in the keyboard to obtain radically variable paremeters, as for example, the location of the "makepoint" of the switch at various positions between the start and end of "key travel." | ||||||

| A membrane switch includes a substrate having a plurality of first conductors formed thereon and a flexible membrane having a plurality of second conductors formed thereon. A spacer is positioned between the substrate and membrane and there are openings in the spacer in register with aligned first and second conductors. To isolate the switch membrane, there is a pressure reduction membrane overlying and in contact with the exterior of the switch membrane and an isolation membrane positioned on top of the pressure reduction membrane. Areas of the pressure reduction membrane in register with the spacer openings are formed to reduce the required force thereupon to effect movement of the switch membrane. | ||||||

| 155 | Collated cable matrix switch | US32715273 | 1973-01-26 | US3886335A | 1975-05-27 | HENDRICKS JOHN E |
| In a matrix of switches disposed in rows and columns, a plurality of first discrete conductors are deposited on the surface of a first backing member to extend in a first direction and a plurality of second discrete conductors are deposited on the surface of a second backing member to extend in a second direction. Dielectric spacing means is disposed between the first and second backing members to maintain the first and second conductors in a normally spaced relationship. The spacing means defines a plurality of openings each extending between an associated pair of the first and second conductors which define one of the switches. By pressing the associated pair of conductors into relative engagement through the associated opening in the spacing means, a signal on the associated first conductor is switched to the associated second conductor. The second conductors can extend through a pair of the switches and can be bisected therebetween to increase the number of discrete switches in the matrix without increasing the number of conductors. A bar clamp provides an interface between the switches in the matrix and the electronics associated with the controlled operations. A method for making the matrix of switches includes the steps of providing a spool for each of the backing members, the conductors, and the spacing means, and guiding the conductors and the spacing means in a spaced relationship onto the backing member. This process can be performed at high speed with inexpensive materials to significantly reduce the cost of manufacturing the matrix of switches.

| 156 | Modular touch sensitive indicating panels with touch and light transmissive overlay cover membrane containing visible printed indicia | US3777222D | 1972-05-12 | US3777222A | 1973-12-04 | HARRIS T |
| Presently described touch sensitive indicating panels have thin but durably constructed plastic overlay membranes serving to: (a) transmit touch actuation pressure to underlying elastic diaphragm switch contacts arrayed at selected points of a pre-dimensioned grid; (b) transmit rear projection light indications received through spaces between switch grid conductors from suitably positioned light sources; (c) transmit alphanumeric light indications from suitably located arrays of light sources; (d) allow viewing of fixed information behind panels through suitably located areas; (e) display permanent indicia of artwork and nomenclature designating touch sensing and rear projection sites and functions; and (f) complete a housing enclosure. Panels for various host systems (e.g. computers, peripheral terminals, etc.) are assembled in various shapes and function types from a limited inventory of modular touch switches and control circuits. In the switch modules crossed grids of spaced conductors, which are prefabricated on transparent flexible support films, have pairs of spaced parallel contact segments subject to flexure into contact at positions offset from the grid intersections. The grids have predetermined dimensions of intersection spacing and the offset contact pairs have specific design features for enhanced integrity and reliability of contact operation. Modular sensing circuits perform the functions of: scanning contacts of the panel switch modules for touch closure conditions; representing locations of closure conditions at predetermined locations; providing audible feedback (beep tone) of contact sensing, and translating sensed contact conditions into panel light indications and/or electrical control functions. Various arrangements are described for producing complex control and indicating effects based upon combinational sensing of particular contact sequences.

| 157 | High speed serial scan and read-out of keyboards | US3745536D | 1971-03-01 | US3745536A | 1973-07-10 | KLEHM W |
| Relates generally to the production of electrical signals from a keyboard, each key of which is individually operatively associated with a switching device whose activation to electrical conductive condition is controlled by the displacement of the key. These switches are hermetically sealed from the atmosphere and are electrically scanned in succession at relatively high speeds and at a repetitious rate such that several scanning cycles occur during the normal activation of a selected key. The keyboard mechanism also includes a shift register having one more bit position than the number of switch devices and into which a bit is introduced into the ''''one'''' position at the instant the scan encounters a closed switch of the keyboard. This bit is then shifted through the register in timed relation to the scan of the remaining key switches and unloaded into the last bit position of the register. A detector senses the presence of a bit in both the ''''one'''' position and the last position of the shift register and upon detection of a bit solely in the one position it delivers a signal indicative of the character represented by the actuated key and upon detecting bits in the two extreme positions of the shift register it nullifies the delivery of such a signal.
