Abstract:
A piezoelectric thin-film electromechanical microsystem (MEMS) device (18) comprising an RF-MEMS switch (14) and a bulk acoustic wave piezoelectric thin-film RF resonator (10) mounted on a substrate (12) provided with an acoustic mirror (28). The resonator comprises a thin film portion (16) between the two metal electrodes (20, 24). The switch (14) comprises a two-layer crossarm with an insulator layer (38) combined with a different portion (36) of the piezoelectric film (18) and having a movable metal contact (50) engageable with stationary metal contacts (46, 48) when the crossarm is bent by a voltage across the control electrodes (40, 42).
Abstract:
A flexible, pressurizable signal processing device such as a keyboard device (10) is made of resilient layers (12, 14) of plastic material having a common periphery (15), with molded keys (16) which are deformable when pressed so as to send a signal via a conduit (24) to an electrical device (26). The keys are arranged with a flexible electrical circuit (22) thereattached and with interconnected inflation channels (13) therebetween, such that when a key is depressed an associated conductive trace (20) establishes a proper complete circuit.
Abstract:
In some examples, techniques are provided for quick haptic feedback, without the use of a controller, which is local to individual, non-actuating keys, such as keys of a thin keyboard or keypad. The haptic feedback may be in the form of a simulated "key-click" feedback for an individual key that is pressed by a user such that the finger used to press the key feels the tactile sensation. The haptic feedback mimics the tactile sensation of a mechanical key (e.g., buckling spring, pop-dome key switch) to give a user the perception that they have actuated a mechanically movable key.

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 The system also uses a communications protocol allowing the receivers to respond to signals from transmitters and/or repeaters.
