  • Patent number: 11867567
    Abstract: In a thermo-physical property measurement instrument, a light shield that shields from light except for an aperture is provided facing the front surface of a sample thin film of a sample. Heating light of repeated pulse that is output from a heating laser irradiates the sample thin film through the light shield. Temperature measurement light of continuous light that is output from a temperature measurement laser is applied to a measurement position a predetermined distance away from a heating light irradiation position on the sample thin film. A photodetector detects reflected light of the temperature measurement light off the sample thin film, and a computer acquires a thermo-reflectance signal that was digitally converted by an AD converter. The computer calculates a thermo-physical property value in the in-plane direction of the sample thin film of the sample on the basis of the acquired thermo-reflectance signal.

  • Patent number: 10268439
    Abstract: In a prediction system, terminal devices having monitors connected thereto and a server can communicate with each other through a network. Each terminal device acquires a luminance measured by a corresponding monitor and transmits it to the server. The server predicts the life of the monitors on the basis of information from the respective terminal devices and notifies the predicted life. The server previously stores information about the installation locations of the monitors. The server notifies the predicted life in such a manner that the installation location of each monitor and the predicted life are associated with each other. Each terminal device acquires, from a corresponding monitor, a measured luminance, a brightness setting at the time when the luminance has been measured, and information about the time when the luminance has been measured and transmits them to the server.
