  • Patent number: 5785426
    Abstract: Pyrometer with a probe beam superimposed on its field-of-view for furnace temperature measurements. The pyrometer includes a heterodyne millimeter/sub-millimeter-wave or microwave receiver including a millimeter/sub-millimeter-wave or microwave source for probing. The receiver is adapted to receive radiation from a surface whose temperature is to be measured. The radiation includes a surface emission portion and a surface reflection portion which includes the probe beam energy reflected from the surface. The surface emission portion is related to the surface temperature and the surface reflection portion is related to the emissivity of the surface. The simultaneous measurement of surface emissivity serves as a real time calibration of the temperature measurement. In an alternative embodiment, a translatable base plate and a visible laser beam allow slow mapping out of interference patterns and obtaining peak values therefor.

  • Patent number: 5784401
    Abstract: Methods and apparatus are disclosed for measuring the temperature distribution or profile of a specimen at high resolution. An apparatus comprises a thin-film membrane formed of a first thermo-electrically conductive material, the membrane having a first major surface for holding the specimen. The apparatus also comprises a probe having a tip radius operable to contact a second major surface of the membrane opposite the first major surface. The tip radius comprises a second thermo-electrically conductive material that is different from the first thermo-electrically conductive material so as to generate, by the Seebeck effect, a thermo-electromotive force (TEMF) between the tip radius and the thin-film membrane. The probe can be scanned across the second major surface; the TEMF can be measured, processed, and displayed to produce a temperature profile of the specimen.

  • Patent number: 5778818
    Abstract: Indicators and methods of indicating are disclosed. Intended primarily for use with medicine containers, the devices typically indicate the number of doses of medication ingested or remaining to be taken by a patient during a particular period. These devices additionally provide tactile assistance to patients in appropriately repositioning the indicator arms and, when used correctly, may reduce the possibility of patient overdose by restricting improper attempts to advance the indicator arm.

  • Patent number: 5771836
    Abstract: This invention concerns a water skier warning flag system of the type wherein the slackening of the tow rope causes a warning flag at the transom of the ski boat to be raised. A mechanical device mounted on the rear of the transom of a ski boat includes a lever having a normally vertical long lever arm for holding a longitudinally-mounted (normally vertical) standard of a warning flag; and this long lever arm also has a connection point to a ski tow line. The other (short) lever arm is urged by a compression spring to maintain the long lever arm vertical. When a skier is skiing, the tension on the tow line pulls the long lever arm down to horizontal against the pressure of the compression spring; and when the tow line goes slack, the spring pressure returns the long lever arm to vertical.

  • Patent number: 5772323
    Abstract: The present invention relates to a totally novel device and process useful for the measurement of the temperature of a radiating body. More particularly, the present invention relates to a device that enhances the resolution and repeatability of the measured temperature of the radiating body by fitting a mathematical correlation to the emitted radiation spectra, generating calculated radiation intensities at specified wavelengths using the mathematical correlation, and then generating a suite of individual two-wavelength temperature values, which can be statistically evaluated and averaged for a final, measured temperature.

  • Patent number: 5772328
    Abstract: An optical temperature measuring device utilizes thermochromic semiconductors which vary in color in response to changes in temperature. The thermochromic material is sealed in a glass matrix which allows the temperature sensor to detect high temperatures without breakdown. Cuprous oxide and cadmium sulfide are among the semiconductor materials which provide the best results. The changes in color may be detected visually using a sensor chip and an accompanying color card.

  • Patent number: 5772322
    Abstract: A temperature sensing device employs a resonant polysilicon beam, in combination with electrical circuitry for oscillating the beam at its natural resonant frequency, to sense changes in temperature. The resonant beam is formed as part of a silicon layer, and the silicon layer is in direct contact with a dissimilar material. In one version of the device, the silicon layer is deposited onto a sapphire substrate by low pressure chemical vapor deposition. In another version, the beam is part of a polysilicon layer deposited onto a silicon wafer substrate. The silicon substrate is thinned, then thermoelectrically bonded to a borosilicate glass substrate. In still another version, the silicon substrate is selectively thinned and has deposited thereon a TCE mismatched material. In all versions, temperature is sensed based on a thermal mismatch of the two dissimilar materials.

  • Patent number: 5769540
    Abstract: Thermal, optical, physical and chemical characteristics of a substrate (11) surface are determined with non-contact optical techniques that include illuminating (23) the surface with radiation having a ripple intensity characteristic (51), and then measuring the combined intensities (53) of that radiation after modification by the substrate surface and radiation emitted from the surface. Precise determinations of emissivity, reflectivity, temperature, changing surface composition, the existence of any layer formed on the surface and its thickness are all possible from this measurement. They may be made in situ and substantially in real time, thus allowing the measurement to control (39, 41) various processes of treating a substrate surface. This has significant applicability to semiconductor wafer processing and metal processing.

  • Patent number: 5771261
    Abstract: The present invention comprises methods and apparatus for assessment of the effects mental stress involving the measurement of periodic changes in skin perfusion. Using a remotely mounted infrared camera, dynamic area telethermometry (DAT) measures the autonomic nervous activity by monitoring and quantitatively analyzing the modulation of cutaneous perfusion. When people gets "nervous" their sympathetics "act up" and they blush (vasodilates) or becomes pale (vasoconstricts). A DAT test of the face proves to be a superior "lie detector" test since emotional stress is reflected in an autonomic nervous response that can be measured remotely. DAT is much more sensitive than any visual assessment of skin color or than instrumental measurement of diaphoresis. Not only is it more reliable than currently used polygraph tests, but its non-contact administration is so simple and innocuous that it could be done without the subject's awareness.
