    摘要： In an embodiment, a tile device includes a plurality of piezoelectric transducers elements and a base adjoining and supporting the plurality of piezoelectric transducers elements. The base includes integrated circuitry programmed to successively configure operational modes of the tile, according to a pre-programmed sequence, to successively select respective subsets of the piezoelectric transducers elements for activation. The integrated circuitry includes pulser logic to selectively activate such subsets, and demultiplexer logic to communicate from the tile sense signals resulting from such activation. In another embodiment, the demultiplexer logic is part of a first voltage domain of the tile, and the pulser logic is part of a second voltage domain of the tile. The base may include circuitry to protect the demultiplexer logic from a relatively high voltage level of the second voltage domain.

    摘要： A piezoelectric transformer 101 includes a piezoelectric element 506. Two primary side electrodes 507A, 507B exist on the primary side of the piezoelectric element 506. The primary side electrodes 507A, 507B are coupled by a resistor 515 formed from a conductive coating. A discharge current is discharged via the resistor 515 to protect a semiconductor component from the discharge current. Since neither a short-circuit terminal nor conductive jig is required, electrostatic discharge damage to a semiconductor component can be prevented by a low-cost arrangement.

    摘要： The invention relates to an apparatus (1) for producing a plasma (P), comprising a control circuit (3) which is electrically connected to a piezoelectric transformer in order to excite the piezoelectric transformer (5). The invention further relates to a hand-held device (100) that uses the apparatus (1). The piezoelectric transformer (5) is constructed of several layers (S1, S2,..., SN). The control circuit (3) is implemented on a circuit board (7), and the piezoelectric transformer (5) is held over the circuit board (7) by means of a region (6B) of a first end (6). A high voltage is applied to a second free end (8) of the piezoelectric transformer (5), wherein the plasma (P) is produced at atmospheric pressure.
