摘要： A pulsed eddy current sensor probe includes a sensor array board. A number of sensors are arranged on the sensor array board and are operable to sense and generate output signals from the transient electromagnetic flux in a part being inspected. Each of the sensors has a differential output with a positive and a negative output. At least one drive coil is disposed adjacent to the sensors and is operable to transmit transient electromagnetic flux into the part. A first and a second multiplexer are arranged on the sensor array board and are operable to switch between the sensors. The first and second multiplexers are connected to the positive and negative outputs of the sensors, respectively.

摘要： A self referencing eddy current probe for determining conductive coating thickness includes a housing having a reference sample area, for accommodating a reference sample, and a testing edge, for positioning on a component during a coating thickness measurement. The eddy current probe further includes a reference eddy current coil situated in the housing adjacent to the reference sample area and a test eddy current coil, which is located at the testing edge. A self referencing eddy current measurement system, for measuring a thickness of a conductive coating on a component, includes the self referencing eddy current probe. The system further includes a signal generator for energizing the test and reference coils and a comparison module for comparing a test signal received from the test coil and a reference signal received from the reference coil and outputting a compared signal.

摘要： A wireless transceiver for performing ultrasonic measurements includes an uplink transmitter configured to transmit at least one modulated timing pulse signal. Each modulated timing pulse signal is transmitted over a respective uplink wireless channel. The transceiver further includes at least one uplink receiver, which is adapted to receive a respective one of the modulated timing pulse signals from the uplink transmitter and configured to supply an unmodulated timing pulse signal to a respective transducer. The transceiver further includes at least one downlink transmitter, which is adapted to receive an echo signal from the respective transducer, and is configured to extract envelope information from the echo signal and to transmit a modulated echo signal over a respective downlink wireless channel. The transceiver also includes a downlink receiver adapted to receive the modulated echo signals from the respective downlink transmitters.

摘要： A modular, scalable and configurable incoherent light source is provided. The light source includes an array of lighting modules supported on a frame that focuses emitted radiation from the modules at a region of interest. The geometry and physical configuration of the support structures, including the frame, may accommodate various energy intensities at various distances. The modules may be made up of multiple LEDs or other individual light sources, may be of different or the same wavelength, and may be individually controllable for the ultimate lighting application. The light source may be used in medical imaging applications.
