    摘要： A keypad has a substrate carrying an array of sense elements arranged to change state in response to keypad operation, a flexible cover disposed above the substrate and having an exposed surface defining an array of independent key regions, with combination key regions defined in interstices between adjacent independent key regions, and an array of discrete snap elements extending between the cover and the substrate and spacing the cover from the substrate. The snap elements are each located between two adjacent independent key regions and adapted to resiliently collapse as a non-linear response to local pressure against the exposed cover surface to provide tactile feedback of keypad operation. A telephone with the keypad has columns of combination key regions that include multiple numerical columns together including numerical regions corresponding to numerals 0 through 9, with each numerical column containing a plurality of the numerical regions, and at least one other column containing key regions corresponding to punctuation symbols. A touch-sensitive input device (such as a keypad or touchpad, for example) has an exposed, continuous surface defining a planar area, and a grid of sense elements coextensive with the area of the exposed surface and responsive to engagement of the exposed surface by an operator to establish a position of said engagement on the exposed surface. The exposed surface varies in elevation across its planar area to form a series of tactile features. A method of interpreting IACK keypad input includes sensing keypad input corresponding to a combined actuation of a plurality of independent key regions of the keypad, and comparing the sensed input to defined sets of independent key inputs corresponding to combination keys. For sensed inputs found to correspond to a plurality of independent key regions associated with a combination key, a combination key input is registered. For sensed inputs found not to correspond to any combination key, the sensed input is compared to recorded custom chorded key associations. For sensed inputs found to correspond to a recorded custom chorded key association, a sequence of characters according to the corresponding chorded key association is registered. A method of dialing a telephone includes entering a desired sequence of alphanumeric characters including at least one alpha character. The telephone generates a corresponding sequence of numerals by transposing the alpha character into one of the numerals 2 through 9 according to standard telephone keypad letter-number correspondence.

    摘要： A keypad has both hill keys (12) that provide a corresponding output when individually pressed, and valley keys (14) are labeled to correspond with an output that results at least from the simultaneous or near-simultaneous manipulation of a predetermined set of two or more hill keys (12) adjacent the valley key (14). Pairs of hill keys (12) are joined to form elongated dual keys (16) that provide a nominal effective key width (H) substantially equal to a nominal effective key width (V) of the valley keys.

    摘要： Keycaps of a keypad or regions of a digitizer contain an electrophoretic ink. An electric field is passed through selected regions of the ink to form a desired graphic label visible at the exposed surface of the keycap or region. In some cases, conductors within the keypad or digitizer alter the ink. In other cases, the keycaps or regions are placed proximate a printer that alters the ink, such as to initialize a generic keypad for a given function. A keypad contains a MOD key to cycle between language-specific variants of a last-entered character. In some cases, the keys are altered remotely to change their displays, such as to update subscriber service information or advertising.

    a metal snap dome disposed above the printed circuit board, and having an outer edge in electrical contact with a reference trace, the dome having an elevated central region forming a downwardly facing cavity defined at its edge by a ridge disposed above the switch contacts, such that when the snap dome is actuated the ridge
    about the central region engages the printed circuit board in an annular contact zone
    across the switch contacts, making electrical contact between the snap dome and the switch contacts to electrically connect the switch element with the multiple switch contacts.

    摘要： A keypad with both elevated (11) and non-elevated (22) key regions, and key switches (12) disposed beneath both types of key regions. The non-elevated key regions each provide corresponding character output based on an operation algorithm that considers activation of at least one adjacent elevated key region as well as activation of the switch below the non-elevated key region. The keypad includes a keymat (41) that is rigidly held at its perimeter in a stretched condition across a switch substrate (23). The key switches include metal snap domes (12) that have an elevated central region (212) forming a downwardly facing cavity (13) defined at its edge by a ridge (214) disposed above the switch contacts (21) that electrically engages multiple switch contacts in an annular contact zone (230).
