Abstract:
A keypad for an electronic device is provided and includes a substrate comprising an array of dome elements, an array of frets, an array of mechanical keys disposed in rows interleaved between the frets, a first deflection web supportively disposed adjacent to the substrate and a second deflection web disposed between the frets and the keys and the first deflection web. The substrate is configured to pre-load the first and second deflection webs toward the keys.
Abstract:
Common platform user interface touch systems (400) including a first housing component (402) having at least one input element (406), a second housing component (404) to define an enclosure with the first housing component (402), a pressure sensing element (412) disposed within the enclosure and configured to receive user input from the at least one input element (406), and an interface controller (418) operably connected to the pressure sensing element (412) and configured to receive inputs from the pressure sensing element (412) to detect user input at the at least one input element (406).
Abstract:
Key switch mechanisms are typically used for mediating user input to computing devices. A key switch mechanism provides immediate tactile feedback to a user upon user-actuation thereof. Unlike touchscreen interfaces, existing key switch mechanisms of conventional keyboards do not provide a user with a dynamically changeable interface. Described is a key switch mechanism that comprises a circuit module, a key cap and a linkage mechanism for guiding travel of the key cap substantially along a travel axis. The linkage mechanism comprises a positioning board and a main link pivotably inter-coupling the positioning board and the key cap. The main link substantially impedes tilt of the key cap away from the travel axis during travel of the key cap therealong from a released position, whereat the key cap is biased, to a depressed position whereat a control signal is generated.
Abstract:
Input device manufacture techniques are described. In one or more implementations, a plurality of layers of a key assembly is positioned in a fixture such that one or more projections of the fixture are disposed through one or more openings in each of the one or more layers. The positioned plurality of layers is secured to each other.
Abstract:
A switch comprising: a cover (80); a base (20); and a push button (70) comprising: an elastic touch piece (73) formed in a sidewall of a sliding part of the push button (70), wherein the push button (70) is vertically and slidably installed in a space formed by assembling the cover (80) to the base (20), wherein a free end of the elastic touch piece (73) is configured to abut the base (20) when the push button (70) is pushed, and the free end is configured to abut the cover (80) when the pushed push button (70) is returned.
Abstract:
An electronic device such a telephone (100), PDA (600), or pager (800), includes a manually operable input such as an elastomeric key (102, 103) or button (814), or a touch screen (604) that does not by itself provide substantial tactile feedback upon actuation, and also includes an electromechanical transducer (212) that is capable of generating an impulse of mechanical energy that can be felt. In response to detecting actuation of the manually operable input (102, 103, 814, 604), the electromechanical transducer (212) is driven to produce an impulse of mechanical energy that propagates to the manually operable input (102, 103, 814, 604) and provides tactile feedback to a user.
Abstract:
Control panel (1) located in a vehicle door armrest, comprising a rigid external component (2) and a printed circuit board (PCB) (5) provided with a capacitive sensor capable of detecting the approach or contact of a user's finger on the rigid external component (2). The rigid external component (2) is provided with operating areas (3), preferably indicated by means of icons (4) and relief, which the user has to operate with his/her finger in order to perform a certain action in the vehicle. The external component is produced in one single piece, thereby considerably reducing the number of components required in relation to conventional control panels.
