Abstract: An apparatus that is comprised of a controller, a digital-to-analog converter (DAC), a temperature sensor, an analog-to-digital converter (ADC), and a voltage controlled oscillator (VCO). The controller to reads temperature data proportional to a temperature of the VCO, reads previously-calculated calibration data based on the read temperature data, determines a frequency command signal based on the read previously-calculated calibration data, and outputs the frequency command signal. The DAC converts the frequency command signal into a frequency analog signal. The temperature sensor produces the temperature signal. The ADC converts the temperature signal into the temperature data. The VCO produces an output frequency based on the frequency analog signal.

Abstract: Electrospinning nozzles include novel constructs for providing spinning pores that define the origin of jets of fiber-forming media. In some embodiments, a film covers relatively large holes in a nozzle body and provides spinning pores aligned with such large holes. In some embodiments, conductive tubes are secured at or about relatively large holes in a nozzle body and provide spinning pores fluidly communicating with fiber-forming media at such large holes. In yet other embodiments, nozzle bodies are provided with circular or semi-spherical surfaces having a plurality of spinning pores.

Abstract: A test system 100 that can accept a plurality of plug-in electronic cards in Xi Slots 126 or PXI slots 134 is described. The test or source measure switching system 100 includes a sequencer or sequence engine 130 which is fully capable of executing opcode instructions having potentially indefinite completion times and monitoring multiple asynchronous inputs simultaneously without interrupts. The sequencer 130 is sequential and deterministic to approximately 10 microsecond resolution. The sequencer 130 includes a trigger router which can be a fully configurable trigger input and trigger output routing matrix. Every trigger input can be configured via several detection modes such as active high, active low, level high and level low. Also, trigger outputs can be configured to be triggered on single, multiple or auto triggers if set.

Abstract: A thermal interface device (100) includes a base member (102) and a pocket (104) which is filled with a thermally conductive material or medium such as diamond dust suspended in a solvent such as propylene glycol or a thermally conductive material such as thermally conductive rubber. The pocket (104) is hermitically sealed to the base member (102) in order to keep the thermally conductive material within the pocket. The filled pocket (104) forms a deformable “pillow” having a high thermal conductance. The deformable pocket (104) can contour to the shape of a device it is pressed against such as an electronic device undergoing testing.

Abstract: A switch matrix module (600) includes programmable stub breakers (508-512, 514-518) which can break off the bus and isolate unused portion of the switch matrix. Using three-way stub breakers (508-512, 514-518) at the matrix front-ends that can either completely isolate a middle matrix or cut off stubs left or right of the destination and source matrices, allows for the formation of very large matrices which have improved operational performance.

Abstract: A switch matrix assembly provides for excellent frequency performance while maintaining good isolation, insertion loss, and crosstalk performance. The switch matrix assembly can include an internal bus connector card that helps eliminate or reduce stubs on a matrix star card that is part of the switch matrix. A stack bus connector card can be added in order to allow for identical busbars on other matrix star cards to be connected “stubless.” The switch matrix can also include bus stub isolator card(s) in order for busbar stubs to be broken-off reasonably close to final termination points. The stackable design of the switch matrix assembly allows for a fairly dense design which helps save space, improves serviceability, and improves overall switching performance.

Abstract: A continuous cardiac output monitor a general-purpose monitoring console with local display and communication facilities, and a module removably interfacing with the console to configure the latter for performing continuous cardiac output monitoring. The module includes a switch-mode high efficiency power amplifier for providing electrical heating power at a selected voltage, frequency, and wave form to a heating element of a continuous cardiac output monitoring catheter, which catheter at a distal end portion thereof is immersed in the blood flow of a patient. The catheter effects a temperature transient in the patient's blood flow by the controlled application of electrical resistance heating utilizing electrical power from the power amplifier, and this temperature transient is sensed and used to derive a value for the patient's cardiac output.
