| 21 | Binary code generator | US3761944D | 1972-01-14 | US3761944A | 1973-09-25 | SHIMOJO T |
| A binary code generator for generating a plural bit binary code from keyboard input data comprises a printed circuit including a plurality of conductive lead groupings arranged in registration with a plurality of pushbuttons on a keyboard frame. The circuit board includes a plurality of electrical terminals one of which is operatively electrically connected to a voltage source and the others of which are selectively operatively electrically connected to the lead patterns forming the conductive lead groupings in accordance with the binary code to be generated. Upon actuation of the pushbutton switch all of the lead patterns in the conductive lead grouping associated with that pushbutton are electrically connected together whereby selected ones of the output terminals are electrically connected to the voltage source thereby to produce a binary output code. The keyboard is formed of a single integral sheet of resilient material and includes a plurality of conductive resilient contacts normally spaced from the conductive lead groupings on the circuit board. In a preferred embodiment each of the lead patterns in a lead grouping comprises a plurality of radially extending branches and the contact member is formed with a contact surface in the form of a continuous generally circular rim adapted upon depression of its associated pushbutton to bridge a sufficient number of lead branches in the associated lead grouping to provide effective and reliable switching under all conditions. The contacts are electrically and structurally separated from each other by raised strips formed integral on the resilient keyboard sheet and secured by appropriate means to the circuit board, those strips being effective to reliably maintain independent actuation of individual pushbuttons.

| A switch has a substrate with a plurality of conductor pairs on it. A resilient cover is disposed over the substrate and has depressible areas aligned with the respective conductor pairs. Conducting contact pieces are mounted on the cover below each of the depressible areas, but normally spaced above the pairs. Upon pressing down a given depressible area, the corresponding contact piece moves to engage the conductor pair associated therewith, and thus closes the circuit between them.

| A multiple switch construction for a keyboard or the like produced as a flat panel embodying laminates of electrical conductors in desired patterns, assembled as stratifications in close proximity and separated by spacers. Individual depressible means operating through resilient members urge movable switch elements into contact with fixed electrical conductors with a rotary, wiping action to insure positive electrical contact.

| In a push-button switch using an elastic and electrically conductive contact member movable into and out of engagement with adjacent but separated conductive paths on a substrate, the conductive paths are in the form of helices fitting within one another and the engaging surface of the contact member is provided with a series of lands arranged in a plurality of Lshaped patterns.

| 25 | Switch forms for connecting one terminal to a plurality of other terminals | US3688066D | 1970-12-30 | US3688066A | 1972-08-29 | ADELSON ALEXANDER M; SWARTZ JEROME; TOMASULAO WALTER M JR |
| A switch for electrically connecting a first terminal with a plurality of other terminals. A contact movable into and out of electrical engagement with a plurality of base contacts is employed. The movable contact may comprise physically parallel wires affixed to a flexible plate, as well as wires which radiate radially outwardly from a point. The physically parallel wires may be inclined to the base contacts or the base contacts may be of different thicknesses to achieve sequential contacting of the base contacts by the movable contact. The base contacts may be any convenient shape, or in the form of concentric spirals or interspersed parallel segments or adjacent triangular-shaped segments.

| 26 | Multiple switch construction | US3600528D | 1969-09-25 | US3600528A | 1971-08-17 | LEPOSAVIC WAYNE V |
| Multiple switches produced as a flat panel embodying the basic principle of laminates of electrical conductors in desired patterns assembled as stratifications in close proximity but separated by spacers and covered by resilient material facilitating momentary pushbutton operation of companion switch elements thereof, the separators isolating companion switch elements of the stratified laminates within switching zones identified by indicia or pushbutton pads on the resilient cover.

| 27 | Elastic diaphragm switch | US3594522D | 1969-07-24 | US3594522A | 1971-07-20 | COLGLAZIER DONALD F; SNESRUD MYRON E |
| An elastic diaphragm switch has a diaphragm assembly formed as an airtight interface between a substantially rigid substrate material and a diaphragm of highly flexible film to which is adhered a copper conductive pattern designed to withstand large deflections without fatigue. This is accomplished by an extended length conductor such as a spiral conductor path extending from the diaphragm supported contact to a stationary conductor. Thus the diaphragm switch may be formed of a single thin film and activated by very low-pressure levels.

Devices, methods, and techniques for keyboard scanning are disclosed herein. Keyboard arrangements can include a plurality of keys and a keyboard decoder. Each of the plurality of keys can include at least one drive contact and a plurality of sense contacts. Each drive contact can be connected to an output (drive) line (C) of the keyboard decoder, and each sense contact can be connected to an input (sense) line (1 to 7) of the keyboard decoder such that each key is connected to a unique combination of sense lines. Key presses can be identified by the unique combination of sense lines triggered. The combination of sense lines triggered can be used as an address to a lookup table indicating the function of the various keys. Variations of drive signal properties, e.g., frequency, phase, and waveshape, can be used to further distinguish key inputs and/or provide for a greater number of keys and/or corresponding functions.

| A panel, page or substrate (112) is provided having a tier of electroluminescent (EL) material which forms a pattern corresponding to a series of images (130a-d). When illuminated in accord with a predetermined sequence, the series of images provide an illusion of movement. A sound generator (134) is provided to produce a predetermined audible response associated with the predetermined sequence. One or more flexible membrane switches (164) are coupled to simultaneously activate both the EL material and the sound generator when depressed. The panel may be embodied as a flexible web that is adapted to roll up over a spring loaded shaft. | ||||||
