    摘要： Provided is an ultrasound apparatus including: a transmitter configured to generate and output a transmission signal; an ultrasound probe configured to convert the transmission signal output from the transmitter into an ultrasound signal and transmit the ultrasound signal to a target object, and receive an echo signal reflected from the target object and output a reception signal on the basis of the echo-signal; a transmission/reception switch configured to attenuate the transmission signal output from the transmitter and output the attenuated transmission signal, and output the reception signal output from the ultrasound probe; and a receiver configured to receive the attenuated and output transmission signal and the output reception signal, and detect transmission waveform information on the basis of the attenuated transmission signal.

    摘要： Components of a device may transmit signals between one another using piezo electric transducers (PETs). In a basic system, a first PET may be coupled to and/or in contact with a first location on a member. A second PET may be coupled to and/or in contact with a second location on the member and separated from the first PET by a distance. The first PET may receive a signal (e.g., an electrical voltage) and convert the signal to a mechanical force/stress causing vibration of the member. The vibration may propagate through the member to other locations about the member. The second PET receive the vibration and may convert the vibration back to the signal, such as by converting mechanical force/stress to the electrical voltage (i.e., the signal). A similar process may be performed in reverse to enable the first and second PET to provide two-way communication.

    摘要： A electrical switch has a first substrate, a first conducting layer disposed on the first substrate, a first dielectric layer disposed on the first conducting layer and a second conducting layer disposed on the first dielectric layer, and the second conducting layer disposed on the second substrate, and a conductive via connected to the first conducting layer and extending through the first dielectric layer. Active dielectric has a first conductor, a first dielectric layer disposed on the first conducting layer, one or more electrical switches disposed on the first dielectric layer, a dielectric layer disposed between neighboring electrical switches, the second dielectric layer disposed on the last electrical switch, and the second conducting layer disposed on the second dielectric layer.
