摘要： A reconfigurable linear array of sensors (e.g., optical, thermal, pressure, ultrasonic). The reconfigurability allows the size and spacing of the sensor elements to be a function of the distance from the beam center. This feature improves performance for imaging systems having a limited channel count. The improved performance, for applications in which multiple transmit focal zones are employed, arises from the ability to adjust the aperture for a particular depth.

摘要： An integrated switch matrix for reconfiguring subelements of a mosaic sensor array to form elements. The configuration of the switch matrix is fully programmable. The switch matrix includes access switches that connect subelements to bus lines and matrix switches that connect subelements to subelements. Each subelement has a unit switch cell comprising at least one access switch, at least one matrix switch, a respective memory element for storing the future state of each switch, and a respective control circuit for each switch. The access and matrix switches are of a type having the ability to memorize control data representing the current switch state of the switch, which control data includes a data bit input to turn-on/off circuits incorporated in the control circuit. The sensor array and the switching matrix may be built in different strata of a co-integrated structure or they may be built on separate wafers that are electrically connected. If the sensors are arranged on a hexagonal grid, the unit switch cells may be arranged on either a hexagonal or rectangular grid.

摘要： A low-voltage transmit/receive switch that acts to protect sensitive low-voltage electronics from high-voltage pulse signals used to drive an ultrasonic transducer. The low-voltage transmit/receive switch comprises a series resistor and a parallel MOSFET pair. The parallel MOSFETs are low-voltage devices. The low-voltage transmit/receive switch is placed between the output of a high-voltage pulser and the input of a receive pre-amplifier. If dual high- and low-voltage pulsers are used, then the low-voltage pulser is connected so that it is also protected from the high-voltage pulse signals by the low-voltage transmit/receive switch. In an alternative embodiment, the low-voltage pulser and the receive pre-amplifier are protected from the high-voltage pulse signals by a high-voltage transmit/receive switch.

摘要： An ultrasonic transducer probe having a highly integrated interface circuit array. Low-voltage transmit control signals from the system are transmitted on the system transmit channels via the ultrasound probe cable and into the interface circuit array. These transmit control signals are routed through the interface circuit array using a dense switching matrix. Once the low-voltage transmit control signals reach individual cells within the interface array, they are decoded and used to control local high-voltage pulser circuits to drive individual ultrasound transducer elements made up of selected subelements that are co-integrated with the interface electronics. The interface cell circuitry further comprises a high-voltage transmit/receive switch, which is closed when the high-voltage pulser is transmitting to protect the low-voltage components.

摘要： An integrated circuit is fabricated by micromachining a hexagonal array of cMUT elements on top of a substrate comprising a hexagonal array of CMOS cells. Each cMUT element overlies a respective CMOS cell in one-to-one correspondence. During layout of the mask for micromachining the cMUT layer, either the hexagonal pattern or the alignment key is rotated until an axis of symmetry of the hexagonal pattern is aligned with an axis of the alignment key. Later, when the mask is superimposed on the CMOS substrate, the alignment key on the mask is aligned with an alignment key on the substrate. This ensures that the cMUT elements formed by optical lithography will be matched to the CMOS cells.
