Abstract: An apparatus for managing the temperature of an integrated circuit having a multiple core microprocessor is described. Specifically, thermal sensors are placed at potential hot spots throughout each microprocessor core. A thermal management unit monitors the thermal sensors. If a thermal sensor identifies a hot spot, the thermal management unit adjusts the operating frequency and voltage of that microprocessor core accordingly.

Abstract: An antenna-coupled microbolometer structure comprises a substrate (301), an antenna (102, 103) supported by the substrate, and a thermally sensitive element (101, 305) connected to the antenna and arranged to dissipate electric currents induced into the antenna. Both the antenna (102, 103) and the thermally sensitive element (101, 305) comprise material that is susceptible to achieving a superconductive state below a certain critical temperature. The thermally sensitive element (101, 305) is supported at a distance from the substrate (301) leaving an empty gap (306) between the thermally sensitive element (101, 305) and a surface of the substrate (301).

Abstract: Methods and systems are disclosed for detecting overheating in an optical device before harmful consequences, such as severe local heating, can result. In one embodiment of the invention, a blackbody emitter is disposed in close proximity to a therapeutic optical fiber to absorb therapeutic radiation at a fault and re-emit blackbody (infrared) radiation. The emitter can be coupled to the fiber but, during normal operation, lies outside the optical path between the output of the laser radiation and the site of treatment. Systems and catheters incorporating such emitters are also described for effective monitoring of the laser power transmitted along the optical fiber within the phototherapy device.

Abstract: A body temperature detector is particularly suited to axillary temperature measurements of adults. The radiation sensor views a target surface area of the body and electronics compute an internal temperature of the body as a function of ambient temperature and sensed surface temperature. The function includes a weighted difference of surface temperature and ambient temperature, the weighting being varied with target temperature to account for varying perfusion rate. Preferably, the coefficient varies from a normal of about 0.13 through a range to include 0.09. The ambient temperature used in the function is assumed at about 80null F. but modified with detector temperature weighted by 20%.

Abstract: A broadband, very low phase noise, temperature stable, sync loss free voltage controlled oscillator (nullVCO circuitnull) is described. One use of the invention would be in a radio receiver for receiving phase modulated signals from a remote transmitter. In one embodiment of the invention, the VCO circuit is disposed on a printed wiring board (nullPWBnull) spaced apart from the PWB on which the synthesizer circuit is disposed. The VCO circuit may comprise a resonator, a voltage controlled oscillator, a varactor, and one or more buffer amplifiers. Additionally, a positive temperature coefficient resistive heating element (nullPTCnull) may be included. In a preferred embodiment, the resonator, voltage controlled oscillator, varactor, and buffer amplifiers may be disposed on one side of the PWB and the PTC may be disposed on the other side of the PWB. Blind vias in the PWB enhance heat transfer from the PTC to the circuit elements on the other side of the PWB. The PWB may be encased in a thermal insulator.

Abstract: Apparatus for delivering a constant radiant energy delta to calibrate a railway hot box detector. A wheel including an aperture is rotatingly supported within the apparatus. A temperature sensor senses the temperature of the wheel, and a radiant energy source is mounted within the apparatus such that the wheel, when rotated, periodically allows radiant energy to be transmitted directly from the energy source through the aperture to a hot box detector being calibrated. A processor is provided to receive the temperature sensed by the temperature sensor and operate the energy source at a radiant energy setpoint by determining the present temperature of both the energy source and the present temperature of the wheel and the desired radiant energy delta.

Abstract: A beam characterization monitoring apparatus receives an input VUV beam and measures a beam profile characteristic of the beam. An enclosure has an interior substantially free of VUV photoabsorbing species and configured for receiving the input VUV beam therein. Optics within the enclosure separate the input VUV beam into a first component for measuring a near field beam profile characteristic and a second component for measuring a far field beam profile characteristic. A detector coupled with the enclosure via a beam path substantially free of VUV photoabsorbing species preferably detects the first and second components simultaneously. A quantum converter is preferably disposed along the beam path before the detector for converting the VUV beam to a beam having a wavelength above 240 nm. A second detector preferably detects an energy of an additional component of the input VUV beam.
