  • Publication number: 20130308675
    Abstract: An apparatus and method of determining the optimal plant canopy temperature of a plant by measuring chlorophyll a variable fluorescence is described. Leaf samples taken from the plant are placed on a temperature gradient device, exposed to light for an amount of time, and the variable fluorescence emitted from the leaves is measured along with the temperature. Calculations of Fv/Fo over a period of time are used to determine the optimal plant canopy temperature for a plant or a crop. The apparatus and method can be used to compare specific cultivars, to assess the results of plant breeding programs, and to assist in crop management procedures.

  • Patent number: 8585285
    Abstract: An electronic thermometer is configured for selectable predictive modes based upon the same predictive algorithm. A mode selector is adapted for user selection between several modes of operation of the thermometer. Each mode of operation utilizes the same predictive algorithm for estimating the temperature of the subject before the thermometer reaches full equilibrium. Different modes offer users a selection for striking the appropriate balance between response time and precision, based upon user preferences and needs.

The substrate may be disposed on a substrate support within a treatment region and a shadow ring may be disposed between the laser source and the surface of the substrate. The shadow ring may be selectively opaque to the laser beam and transparent to the emitted light.

  • Patent number: 8430561
    Abstract: The present invention is drawn to a non-contact thermometer that is operable to emit a first light having a first color to create a spot of a first color at a reference target and to detect the temperature of the reference target. The non-contact thermometer is additionally operable to establish a temperature difference threshold. In use, once a temperature difference threshold is selected and once the temperature of the reference target is detected, the non-contact thermometer may detect a temperature of another target. Further, if the detected temperature of the other target is outside of the temperature difference threshold as compared to the temperature of the reference target, the non-contact thermometer is operable to emit a second light having a second color to create a spot of a second color at the other target.

  • Patent number: 8414187
    Abstract: A temperature sensor includes first and second lower electrodes, a ferroelectric layer having polarization, a semiconductor layer; and first to third upper electrodes. The second upper electrode is interposed between the first upper electrode and the third upper electrode in a plan view. The semiconductor layer includes a first channel disposed between the first upper electrode and the second upper electrode, and a second channel disposed between the second upper electrode and the third upper electrode. The ferroelectric layer includes a first ferroelectric part disposed below the first channel and a second ferroelectric part disposed below the second channel. A polarization direction of the first ferroelectric part is opposite to a polarization direction of the second first ferroelectric part. The temperature is calculated based on the output voltage from the second upper electrode and the voltage applied to the first upper electrode.

  • Publication number: 20130083822
    Abstract: An electronic thermometer includes a probe adapted to be heated by a subject for use in measuring a temperature of the subject. At least one temperature sensor detects a temperature of the probe. An IR emitter emits an infrared signal from the probe. And an IR detector detects the infrared signal emitted by the IR emitter. The detection of the IR signal by the IR detector indicates that the probe is received in a probe cover.

  • Publication number: 20130083823
    Abstract: A thermometer for measuring a temperature of a subject. The thermometer includes a probe for insertion into an orifice of the subject. An electromagnetic radiation sensor at the probe senses electromagnetic radiation within the orifice of the subject. The electromagnetic radiation sensor generates data indicative of both the temperature of the subject and one or more anatomical images of the subject. A controller receives the data from the electromagnetic radiation sensor. The controller generates a temperature image on the display indicative of the computed temperature of the subject and one or more anatomical images of the subject on the display.

  • Patent number: 8407616
    Abstract: A graphical user interface facilitates methods for analyzing a temperature distribution across a scene that is captured by a thermal imaging device. Preferably, the interface includes a both a two-dimensional image of the captured scene and a three-dimensional representation of the captured scene. The three-dimensional representation is formed by a plurality of pixels, each of which are coded by a qualitative value from within a range of qualitative values, and each value, within the range, corresponds to a temperature. Each of the plurality of pixels is arranged, in a first and a second dimension of the three dimensions, according to a position of a corresponding pixel of the two-dimensional image, and, in a third dimension, according to a magnitude of the temperature associated therewith.

  • Patent number: 8393784
    Abstract: A method for identifying types of flaws in a composite object includes: a) rapidly heating the surface of the object; b) recording pixel intensities in a sequence of IR images; c) determining temperature-versus-time data for each of the pixels from the IR images; and d) determining what type of flaw if any corresponds to each of the pixels using the temperature-versus-time data determined in step (c). A contrast curve derived from the temperature-versus-time data may be used in determining what type of flaws if any corresponds to each of the pixels. The contrast curve may be determined by subtracting a synthetic reference curve from a temperature time curve from the temperature-versus-time data. The types of flaws may be determined from size and/or shapes of peaks in the contrast curves. Some flaws are delaminations, layers of porosity, and uniformly distributed porosity.

  • Patent number: 8382367
    Abstract: A probe for an ear thermometer has a mounting bracket, a light module, a temperature sensor and a probe tube. The light module and temperature sensor is mounted on the mounting bracket. The light module is capable of radiating different colored lights to respectively indicate normal or abnormal body temperature. The probe tube covers the light module and temperature sensor and is light-pervious. Because the probe of the ear thermometer indicates the body temperature by different colored lights and/or numerals, using the ear thermometer with the probe is easy, simple and instinctive when compared to conventional thermometers that use LCD display to show numerical values.

  • Patent number: 8371748
    Abstract: A temperature measuring apparatus comprises a casing, an infrared sensor assembly, a probe, and a trigger device. The infrared sensor assembly is disposed in the casing. The trigger device is connected between the casing and the probe in such manner that when the probe moves toward the casing, the trigger device is activated by the probe to trigger the infrared sensor assembly to proceed sensing. The temperature measuring apparatus could be operated to measure without pressing any measuring button, so that the temperature measuring apparatus could have a stable operation in the measuring process. Hence, the error of the temperature measuring is reduced and the operation is more convenient.
