摘要： An ultrasonic sensor includes an ultrasonic transducer; a first voltage output circuit to output a transmission voltage signal that oscillates between a first high voltage and a first low voltage, supplied to a first terminal of the ultrasonic transducer; a reception circuit to detect a voltage signal generated at a second terminal of the ultrasonic transducer; and the second voltage output circuit to output a second high voltage smaller than the first high voltage. The first voltage output circuit includes a first switching unit to perform switching between supplying the transmission voltage signal in ultrasonic transmission; and fixing a potential of the first terminal in ultrasonic reception. The second voltage output circuit includes a second switching unit that performs switching between supplying the second high voltage to the second terminal in ultrasonic transmission; and electrically separating the second voltage output circuit from the second terminal in ultrasonic reception.

摘要： An acoustic element integrated circuit includes cells, being arrayed two-dimensionally on a same curved surface, wherein capacitive acoustic-elements having vibration membranes are allocated by unit number in each of the cells. Each of the cells encompasses an intra-cell circuit, which includes an exciting circuit for driving collectively portions by the unit number, the portions having transmitting functions of the acoustic-elements, and a reception circuit for processing collectively received signals transferred from portions by the unit number, the portions having reception functions in the acoustic-elements. Here, the exciting circuits are sorted into a chip in which high-voltage drivers for exciting the vibration membranes are merged and a chip in which circuits operated at voltages lower than the high-voltage drivers are merged, and the cells are operated two-dimensionally, by individually controlling the intra-cell circuits so that cells can be driven independently.

摘要： A signal generator generates an electrical signal that is sent to an amplifier, which increases the power of the signal using power from a power source. The amplified signal is fed to a sender transducer to generate ultrasonic waves that can be focused and sent to a receiver. The receiver transducer converts the ultrasonic waves back into electrical energy and stores it in an energy storage device, such as a battery, or uses the electrical energy to power a device. In this way, a device can be remotely charged or powered without having to be tethered to an electrical outlet.
