Abstract:
A self-powered switching system using electromechanical generators generates power for activation of a latching relay, switch, solenoid or latch pin. The electromechanical generators comprise electroactive elements that may be mechanically actuated to generate electrical power. The associated signal generation circuitry may be coupled to a transmitter for sending RF signals to a receiver which actuates the latching relay. The use of mechanically activated membrane switches on the deflector or on a keypad allows multiple code sequences to be generated for activating electrical appliances or an electromechanical locking system.
Abstract:
A non-movable switch is located behind an interior trim component of a motor vehicle. The location of the switch is hidden until a status condition of the motor vehicle occurs. When the status condition occurs, the location of the switch becomes visibly apparent and the switch becomes active and operable.
Abstract:
A first electrode and a second electrode are disposed on a base board. A resist is formed on the base board so as to cover the first electrode. A capacitance-operated silicon rubber sensor is provided on the base board so as to cover the resist and the second electrode. A click rubber is disposed above the silicon rubber sensor. A button deforms the click rubber so as to press down the silicon rubber sensor and the resist. The silicon rubber sensor and the resist generates an analog output signal between the first and second electrodes in proportion to a force pressing the button, when the pressing force is larger than a predetermined pressing force enough to deform the click rubber so as to establish the output signal.
Abstract:
The present invention includes a flexible, pressurizable keyboard made of resilient layers of plastic material, with molded keys which are deformable when pressed so as to send a signal to an electrical device. The keys are arranged with a flexible electrical circuit thereattached, which when depressed, establish a proper complete circuit.
Abstract:
Apparatus for use in a computer keyboard for cursor control is disclosed. The apparatus includes a compound key which serves for both typing a character and for pointing operations, i.e. for cursor control like a mouse. For pointing operations, a pointing stick or shaft is pressed in a desired direction by a user for moving a cursor in a corresponding direction on a display screen. The pointing stick is disposed in an aperture that extends through a modified key cap, so that no additional keyboard space is required for the pointing device, thereby obviating a separate mouse, keyboard mounted trackball or the like. In an alternative embodiment, the pointing stick extends through an aperture in the keyboard space bar. In another embodiment, adjacent key caps are modified so as to fit closely around the key cap that houses the pointing stick without interfering with operation of either the pointing stick or the keyswiches.

Abstract:
Die Erfindung betrifft ein Tastenmodul (1), insbesondere für modulare Systeme der Gebäudeelektroinstallation und Türkommunikation, umfassend ein Modulunterteil (2) und ein durch Montage in einer Aufsatzrichtung (AR) mit dem Modulunterteil (2) lösbar verbundenes Moduloberteil (3), wobei in dem Moduloberteil (3) mindestens eine durch Druck in einer Funktionsrichtung (FR) betätigbare Taste (5) montiert ist. Es wird vorgeschlagen, dass das Moduloberteil (3) einen Tastenträger (4) umfasst, an dem die mindestens eine Taste (5) durch eine Montage in einer Tastenmontagerichtung (TR) lösbar festgelegt ist, wobei sowohl die Aufsatzrichtung (AR) des Moduloberteils (3), als auch die Tastenmontagerichtung (TR) und die Funktionsrichtung (FR) der Taste (5) identisch sind und senkrecht auf einer Grundrissebene (GE) des Modulunterteils (2) stehen, und wobei in dem Modulunterteil (2) ein Schaltungsträger (6) mit einer elektronischen Schaltung aufgenommen ist, welche piezoelektrische Elemente enthält, mittels derer unter der Wirkung des in der Funktionsrichtung (FR) auf die Taste (5) ausgeübten Druckes ein Schaltvorgang ausgelöst wird.
