Abstract: A scanning heat flow probe for making quantitative measurements of heat flow through a device under test is provided. In one embodiment the scanning heat flow probe includes an electric current conductor in a cantilever beam connected to a probe tip and coupled to two voltmeter leads. The probe also includes two thermocouple junctions in the cantilever beam electrically isolated from the electric current conductor and the two voltmeter leads. Heat flow is derived quantitatively using only voltage and current measurements. In other forms, the invention relates to the calibration of scanning heat flow probes through a method involving interconnected probes, and relates to the minimization of heat flow measurement uncertainty by probe structure design practices.

Abstract: A method for determining an nulleffectivenull thermal coefficient of a machine comprises the steps of installing one or more temperature sensors (110) at various locations on the machine, positioning a first machine member (60) at a nullknownnull reference Location, relative to a second machine member (42), installing a linear position measuring device (120) to detect changes in position of the first machine member (60) relative to the second machine member (42) along a first axis of movement, periodically acquiring readings from each of the temperature sensors (110) and from the linear position measuring device (120) during a test cycle and compiling the temperature and linear position data into a table. A statistical correlation analysis is performed to determine which of the temperature sensors (110) experiences changes in temperature are most linearly related to changes in the linear position of the first machine member (60) relative to the second machine member (42) and an nulleffectivenull coefficient of thermal expansion is thereafter determined as the rate of change of position, i.e. length, relative to change in temperature. The present method includes using the machine's nulleffectivenull thermal coefficient to calibrate the motion of the machine to compensate for the thermal characteristics thereof.

Abstract: Disclosed is a bit rate discrimination device that accurately discriminates a bit rate regardless of variations in the operating temperature. A photoelectric converter converts an input optical signal into an electric signal, and a bit rate detector detects a bit rate of the optical signal from the electric signal and outputs a discrimination signal indicating the bit rate. A DC amplifier outputs a bit rate detection signal by amplifying the discrimination signal, and a temperature detector detects the operating temperature of the DC amplifier and outputs a temperature signal indicating the detected operating temperature. A variation amplifier outputs a temperature compensation signal by amplifying the voltage level difference between the temperature signal and a predetermined reference signal, so as to cancel variations in an output voltage of the DC amplifier according to the operating temperature. A voltage adder outputs a temperature-compensated bit rate detection signal by combining the bit rate detection signal with the temperature compensation signal. A bit rate discriminator determines the bit rate of the input optical signal depending on the voltage level of the temperature-compensated bit rate detection signal.

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 system (12) and method for determining the closed position of a throttle plate 52 of an internal combustion engine (10) are provided. The system (12) includes a throttle sensor (56), a temperature sensor (70 or 86), and an electronic control unit (ECU) (72). The throttle sensor (56) generates a signal indicative of the position of the throttle plate (52). The temperature sensor (70 or 86) generates a signal indicative of the temperature of a throttle body (50) of the engine (10). The ECU (72) is configured to select one of a first closed position value indicated by throttle sensor (56) signal and a second closed position value retrieved from a memory (94) responsive to the measured temperature. The inventive system is able to minimize inaccuracies in throttle plate position detection by eliminating errors resulting from a change in geometry between the throttle plate (52) and the throttle body (50) of the engine during relatively high temperatures.

Abstract: A smart temperature sensing system and method for improved performance of smart temperature sensors when used in conjunction with an indicating instrument. This sensing system uses a microprocessor-based interface to send a signal to the indicating instrument via an existing communications port. The sent signal may consist of a calibration offset value to correct the indicated temperature in the instrument. This offset value is determined from data resident within a memory device in the temperature sensor.
