Abstract: A wearable ocular surface temperature monitor apparatus used to measure ocular surface temperatures can be mounted around on eye sockets or can be engaged with glasses. The apparatus comprises a frame and an ocular temperature monitor modular disposed on the frame. The ocular temperature monitor modular further includes a plurality of temperature sensors, a signal processing circuit and a transceiver circuit. The temperature sensors are aligned with ocular surfaces for measuring temperatures. The wireless transceiver circuit reads and records the electrical signals output from the temperature sensors, and outwards wirelessly transmits them by the transceiver circuit.

Abstract: A piezoelectric speaker driving system includes a band splitter, a plurality of gain producers, an adder, a piezoelectric speaker, a sound compensator and a gain-adjusting device. The band splitter receives a first audio signal and splits the first audio signal into band signals. The gain producers gain the band signals respectively. The adder receives the gained band signals to generate a second audio signal. The piezoelectric speaker outputs a sound according to the second audio signal. The sound compensator analyzes a sound pressure level of the sound to generate a control signal. The gain-adjusting device adjusts the gains of the gain producers according to the control signal.

Abstract: The present invention provides a semiconductor device integrating passive elements, which applies to analog circuits, wherein capacitors, resistors and inductors are fabricated by a TVS technology. The semiconductor device comprises a substrate; at least one passive element arranged in the substrate; and at least one semiconductor integrated circuit formed in the substrate. The passive element includes a first conductive layer, a first dielectric layer and a second conductive layer, which are stacked sequentially. The first conductive layer and the second conductive layer cooperate with the first dielectric layer to form an equivalent element. The semiconductor circuit is electrically connected with the passive element through the first conductive layer and the second conductive layer to form bidirectional signal transmission paths. The passive elements can be formed on the back side of the substrate to reduce the area occupied by the passive elements in the substrate.
