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.

Abstract: In a vehicle air conditioner, a first air-conditioning control value is calculated based on a surface temperature detected by a non-contact temperature sensor in a temperature detection area of a passenger compartment. When it is determined that an obstacle exists between the temperature detection area and the non-contact temperature sensor, a second air-conditioning control value is calculated according to a temperature information that is influenced less by the obstacle than the detected surface temperature.

When it is determined that the obstacle exists, the first air-conditioning control value is corrected to approach the second air-conditioning control value to calculate a corrected air-conditioning control value, so that the air conditioning state can be controlled satisfactorily.

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.

Abstract: The method measures the temperature, emissivity, and other properties of relatively smooth surfaces radiating thermal energy, and is especially adapted for monitoring semiconductor fabrication processes. Temperature is determined by relating measured radiance to the predictions of the Planck radiation law, using knowledge of the emissivity determined from an analysis of the polarization of the thermally emitted radiance. Additional information regarding the properties of thin films, such as thickness and composition, can be computed from the emissivity or the ratio of the emissivities measured at two independent polarizations. Because the data are obtained from the intrinsic thermal radiance, rather than from an extrinsic light source, the measurement can be performed when it is inconvenient or impossible to provide a light source for reflectance measurements.
