| A keyboard assembly for a mobile device is provided that reduces the separation between keys by reducing the number of required dome switches. A reduction in the number of dome switches can alternatively reduce the amount of real estate taken up by dome switches on a printed circuit board (PCB). Fewer dome switches than keys are provided on a PCB to activate a desired functionality when a key is depressed. The dome switches are each actuatable by and disposed between more than one key, such keys preferably being adjacent keys. Each key has an actuator with at least one arm for actuating a dome switch in an actuated dome switch pattern when the key is depressed. Such a keyboard assembly can be used for any electronic device having a standard QWERTY or Dvorak keyboard layout, a standard telephone or numeric keypad layout, or any other layout of keys. | ||||||

| 127 | Keyboard arrangement and method for identifying a pressed key | US943375 | 1997-10-03 | US5877709A | 1999-03-02 | Timo Ala-Lehtimaki; Paavo Niemitalo |
| In a keyboard arrangement and method for identifying a pressed key according to the present invention, conductor lines (4', 6') at each key (B), which may be connected together, are connected to a ground plane (24, 23, 27) as a response to a pressing (P) of a key. The pressed key (B) is identified by detecting the conductor lines that are connected to the ground plane. All the conductor lines may be connected as pulled-up inputs of a detector circuit, and any conductor line or combination of conductor lines may be used to identify a key. A noticeably greater number of keys may be simply identified with the same number of conductor lines than is possible in a solution according to the prior art. In an advantageous embodiment of the present invention, the means for connecting the conductor lines (4', 5', 6', 7') to the ground plane (27) is a conductive plate (23), which essentially covers the whole keyboard. This also provides a good shield against electrostatic discharges and other interference. | ||||||

| A user configurable control device is particularly suitable for household devices such as remote control transmitters. A variety of function control elements in the form of keys are provided to the consumer who selects a desired set of the control elements.

These projections are in operative alignment with an array of membrane switches disposed on a switching substrate within the control device. The control device includes a front panel that is perforated with a pattern of slots. Each of the control elements has a pair of projecting tabs that look the element onto the control panel so that it is securely retained thereon, but may be released if desired. The projections on the bottom of the element extend through the slots in the front panel to the switching substrate below. The particular pattern of projections is unique to each control element and the corresponding pattern of switch contacts closed upon actuation of the control element determines the function that is performed. | ||||||

The numbers 0-9 carried by each actuator shaft are oriented such that the indicated numbers are readable as a discrete number in standard decimal format corresponding to the numerical value to be encoded. | ||||||
| 133 | Momentary digital encoding device for keyboards | US396039 | 1982-07-07 | US4500757A | 1985-02-19 | Craig E. Rooney |
| A keyboard encoding device which directly develops a digital, valid and reliable output signal without electronic encoding circuitry. The preferred device has a plurality of juxtaposed, flexible conductive strands or wires each having a number of axially spaced impact zones which are either insulated or conductive; corresponding zones on the separate wires are aligned to cooperatively define a series of spaced impact zone sets each made of a unique pattern of conductive and insulated zones. An electrically conductive, rubber-like resilient pad having a series of ridge-like elongated members respectively aligned with corresponding impact zone sets is oriented for shifting of the members into momentary contact with the associated zone sets, whereby electrical contact is made between the ridge members and the conductive impact zones of the set. This directly generates a momentary unique, digitalized output signal. The device is particularly suited for use in impact-type keyboards. | ||||||
| 134 | Universal keyboard and method of producing same | US190177 | 1980-09-24 | US4359612A | 1982-11-16 | Craig E. Rooney |
| An extremely low cost, high speed, full stroke keyboard is disclosed which provides momentary impulse operation. N-key rollover protection and standard tactile feedback. The keyboard includes a plurality of depressible keys mounted on respective upright synthetic resin flaps designed to collapse upon key depression and engage and move an underlying, resilient, U-shaped shifting member; the member in turn engages and shifts another U-shaped resilient element which supports one or more upstanding encoding posts. When the U-shaped element reaches a cocked position it is disengaged from the shifting member and allowed to snap back toward the original rest position thereof independently of subsequent return movement of the key and shifting member. The snap back motion is sensed and a corresponding key output signal developed. | ||||||

| 137 | Pushbutton cantilevered leaf spring contact switch assembly for keyboard type switch arrays | US3746816D | 1971-05-18 | US3746816A | 1973-07-17 | BRADY J |
| A low profile electromechanical keyboard switch, displaying very low electrical bounce. The switch key top bears against a generally cylindrical plunger which has a depressed flat portion on its side engageable with a tactile ball biased by a spring nested in the switch housing. Upon application of a force to the key top which exceeds a threshold value, the tactile ball is displaced from the flat and over the shoulder defined between the depressed flat and the cylindrical portion of the plunger. Sudden, positive movement of the plunger against an underlying contact leaf ensues. The contact leaf is branched into multiple contact fingers, and arranged with respect to an underlying contact plate so that wiping contact occurs between fingers and plate. The switch housing is configured to carry sufficient diodes and resistors to assure full control and encoding functions in the keyboard in which such switch may be mounted.
