  • Patent number: 8901460
    Abstract: After flash irradiation on a semiconductor wafer is started and then the temperatures of front and back surfaces of the semiconductor wafer become equal to each other, the temperature of the back surface of the semiconductor wafer, which has a known emissivity, is measured with a radiation thermometer. The emissivity of the front surface of the semiconductor wafer is calculated based on the intensity of radiated light from a black body having an equal temperature to the temperature of the back surface thereof, and the intensity of radiated light actually radiated from the front surface of the semiconductor wafer. Then, the temperature of the front surface of the semiconductor wafer heated by the flash irradiation is calculated based on the calculated emissivity and the intensity of the radiated light from the front surface of the semiconductor wafer that has been measured after the flash irradiation is started.

  • Patent number: 7881495
    Abstract: The present invention provides for simple and streamlined boresight correlation of FLIR-to-missile video. Boresight correlation is performed with un-NUCed missile video, which allows boresight correlation and NUC to be performed simultaneously thereby reducing the time required to acquire a target and fire the missile. The current approach uses the motion of the missile seeker for NUCing to produce spatial gradient filtering in the missile image by differencing images as the seeker moves. This compensates DC non-uniformities in the image. A FLIR image is processed with a matching displace and subtract spatial filter constructed based on the tracked scene motion. The FLIR image is resampled to match the missile image resolution, and the two images are preprocessed and correlated using conventional methods. Improved NUC is provided by cross-referencing multiple measurements of each area of the scene as viewed by different pixels in the imager.

  • Publication number: 20100312570
    Abstract: A data processing system detects an ordinary consumer positioned in a specific space using an ultrasonic sensor, and detects specific temperature generated from the specific consumable commodity consumed by the ordinary consumer using an IR sensor. In this process, a sensor driving unit integrally moves the ultrasonic sensor and the IR sensor so as to direct them to the ordinary consumer whose position is detected, allows the IR sensor directed to the ordinary consumer to detect a specific temperature, and records the specific temperature and so forth as a consumption behavior. Accordingly, data regarding the consumption behavior, which is uncollectible at the points of time of order intake, production, shipping and selling of the specific consumable commodity, may be collected, making use of the specific temperature generated when the specific consumable commodity is consumed by the ordinary consumer.

    Abstract: A temperature sensing unit senses a plurality of specific temperatures caused by a specific consumable commodity consumed by an ordinary consumer at a specific space, while allowing a behavior storage unit to store q plurality of combinations of the plurality of specific temperatures as a plurality of consumption behaviors of the specific consumable commodity by ordinary consumers. A behavior specifying unit specifies consumption behaviors which match a combination of the plurality of specific temperatures sensed for each piece of the specific consumable commodity, and a data collection unit compiles the specified consumption behavior. Accordingly, data regarding the consumption behaviors of the ordinary consumers, which are uncollectible at the points of time of order intake, production, shipping and selling and so forth of the specific consumable commodity, can be collected.

  • Publication number: 20100292952
    Abstract: A system and method for determining whether a temperature measurement made with an infrared thermometer is accurate is disclosed. An infrared sensor array is used to detect infrared radiation from a target object. By analyzing the relative values of output signals from the individual sensor elements, a determination can be made whether radiation from the target object sufficiently fills the field of view of the detecting element of the instrument. A temperature measurement is considered accurate if this criteria is met.

  • Patent number: 7788545
    Abstract: A broadcast receiving device includes a card slot, a fan, a temperature sensor, a memory component and a control unit. The card slot accepts an IC card. The fan rotates to cool the IC card. The temperature sensor measures a first temperature. The memory component stores correlation information indicating a correlation between the first temperature and a second temperature of the IC card. The control unit acquires the second temperature based on the first temperature and the correlation information. The control unit determines if the second temperature exceeds a predetermined temperature. The control unit switches from a first output mode, in which an audio-video signal is outputted via the IC card, to a second output mode, in which the audio-video signal is outputted by bypassing the IC card, when the control unit determines that the second temperature exceeds the predetermined temperature.
