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 light emitting key is disclosed. A through hole is made through piezoresistive layer; a light source is arranged under the bottom of the light emitting key. When the light source is turned on, light beams shall emit out of the top substrate. The light emitting effect of the key facilitates it to be used in a dark area such as an aircraft flying in the night sky.
Abstract:
Various embodiments of the present invention comprise a signal generator for sending an electrical signal from an expandable, flexible layer of material, the signal generator comprising an upper layer of flexible, resilient material and a lower layer of flexible, resilient material which between them define a cavity for enclosing an expandable material such as a cellular foam or gas, whereupon localized distortion of one of the layers of flexible material, effects a signal generation within the structure, which is transmissible through a proper circuit to an outside electrical device. A circuit may be arranged adjacent a plurality of said keys which senses when several of said keys are depressed in a skewed or sideways manner, so as to effect movement of a cursor or pointer on a monitor in communication with a processing unit and said keyboard.
