  • Patent number: 7434992
    Abstract: A first thermistor 8 and a second thermistor 9 are arranged forwardly and rearwardly of a thermopile sensor 5. A thermopile chip 55 is arranged and interposed between the first thermistor 8 and an integrated thermistor 57. A sensor cover is mounted in contact with front and side portions of a can portion 59 of a thermopile casing 56. A temperature or a radiant quantity of infrared rays on the front portion of the can portion is estimated from a temperature change of the integrated thermistor per second.

  • Patent number: 7399649
    Abstract: An underlying layer ALY of GaN is formed on a sapphire substrate SSB; a transfer layer TLY of GaN with a bump and dip shaped surface is formed on the underlying layer ALY; a light absorption layer BLY is formed on the bump and dip shaped surface of the transfer layer TLY; and a grown layer 4 of a planarization layer CLY and a structured light-emitting layer DLY having at least an active layer are formed on the light absorption layer BLY. A support substrate 2 is provided on the grown layer 4. The backside of the sapphire substrate SSB is irradiated with light of the second harmonic of YAG laser (wavelength 532 nm) to decompose the light absorption layer BLY and delaminate the sapphire substrate SSB, thereby allowing the planarization layer CLY of a bump and dip shaped surface to be exposed as a light extraction face.

  • Patent number: 7398164
    Abstract: The object of the invention is to facilitate the entry of a sensor node and the adoption of a protocol in the existing sensor network system effectively utilizing limited resources of radiocommunication. To achieve the object, the following are provided. A sensor node has a radiocommunication unit that transmits a measured value sensed by a sensor and an identifier of a sensor node as binary measured data. A base station has a radiocommunication controller that receives the measured data from the sensor node, a wire communication controller that transmits the received measured data to a server, a conversion definition information selector that selects conversion definition information corresponding to the identifier included in the measured data out of preset plural conversion definition information and a conversion engine that converts the binary measured data to measured data in a text format based upon the selected conversion definition information.

  • Patent number: 7329044
    Abstract: Temperature states of a clinical thermometer body and an environment are estimated by temperatures measured by a first temperature sensor integrally formed together with an infrared sensor arranged to the distal end of a probe and a second temperature sensor arranged on the bottom side of a probe holder, and processes suitable for the respective temperature states are performed. An estimation error or the reliability of an estimation value is calculated by the temperatures to notify a user of the estimation error or the reliability by an LCD or the like.
