Abstract: A method and apparatus for three dimensional ultrasonic scanning with reduced electronic switching and cabling requirements. The invention includes a body (101) including a relaxor ferroelectric ceramic material and electrodes coupled to opposing surfaces of the body (101). Electronic switches (103) select electrodes (202,212) so as to select column regions (204,206,208) of the body that are arranged adjacent to one another in a row extending radially outward from a central axis of the body (101). A bias voltage source (105) is coupled with the electronic switches (103) for substantially polarizing ceramic material within the selected column regions of the body. A sector controller (103) dynamically configures the electronic switches (103) to rotationally vary a position of the row arrangement of selected column regions (204,206,208). An oscillating voltage source (109) excites the row of selected column regions to emit an acoustic beam, so that the beam rotationally scans the medium as the sector controller (107) rotationally varies the position of the row arrangement.

Abstract: The disclosure relates to a Synchronized Array of Vibration Actuators in a Network Topology that provides for synchronized arrays of low-cost, readily available vibration actuators to emulate superlative single actuators and to bring together sets of these emulated high-performance actuators to create a broad range of desired control effects. Such arrays of actuators may operate in both spatial and temporal modes, which can create haptic effects that relate to the user via their position and orientation in space. The spatial mode may create
h -pulses or the amplitude of a vibrational effect may change based on the position of the device. And the temporal mode may create vibrational effects that interact with the user to create an awareness of time. Additionally modes include a performance mode, a bandwidth mode, a magnitude mode and a reliability mode. The different control modalities may be combined together into a single vector control space, which spans the haptic capabilities of sets and/or subsets of actuators.

Abstract: An ultrasound transducer unit including a plurality of ultrasound transducers transmits and receives ultrasound waves to and from an inside of a subject. In a case where a checking operation unit is operated, a controller controls a driving voltage supply unit such that a driving voltage is supplied with all of the plurality of ultrasound transducers as driving target transducers. In a case where the checking operation unit is operated, a depolarization determination unit calculates, for each ultrasound transducer, a reception sensitivity in a case where an ultrasound wave is received by driving all of the plurality of ultrasound transducers as the driving target transducers, and determines whether or not a depolarization determination value calculated from the reception sensitivity of each ultrasound transducer satisfies numerical conditions. If the numerical conditions are satisfied, a polarization voltage supply unit supplies a polarization voltage to each of the plurality of ultrasound transducers.
