  • Publication number: 20240146807
    Abstract: A sensor device allocation apparatus that allocates a sensor device to an IoT service of the present invention includes a scoring unit that performs ranking of sensor devices satisfying a service requirement by an evaluation function based on specification conditions of the sensor devices and a scheduling unit that determines a control law of the sensor devices ranked by the scoring unit, in which the scheduling unit determines whether a service is satisfied based on collected data of the sensor device collected based on the control law, and the scoring unit corrects the evaluation function and repeats ranking of the sensor devices when the scheduling unit determines that the service is not satisfied.

  • Publication number: 20230338750
    Abstract: A plurality of shift images are generated by shifting a fluoroscopic image by a prescribed increment within a prescribed range in a craniocaudal direction. Then, a normalized correlation coefficient between a DRR image and each of the plurality of shift images is calculated. Next, a shift amount of the shift image corresponding to the largest normalized correlation coefficient among the plurality of normalized correlation coefficients is determined to be the positional deviation.

  • Patent number: 9136108
    Abstract: A method for restoring a porous surface of a dielectric layer formed on a substrate, includes: (i) providing in a reaction space a substrate on which a dielectric layer having a porous surface with terminal hydroxyl groups is formed as an outer layer; (ii) supplying gas of a Si—N compound containing a Si—N bond to the reaction space to chemisorb the Si—N compound onto the surface with the terminal hydroxyl groups; (iii) irradiating the Si—N compound-chemisorbed surface with a pulse of UV light in an oxidizing atmosphere to oxidize the surface and provide terminal hydroxyl groups to the surface; and (iv) repeating steps (ii) through (iii) to form a film on the porous surface of the dielectric layer for restoration.

  • Patent number: 8466411
    Abstract: A method for managing UV irradiation for treating substrates in the course of treating multiple substrates consecutively with UV light, includes: exposing a first UV sensor to the UV light at first intervals to measure illumination intensity of the UV light so as to adjust the illumination intensity to a desired level based on the measured illumination intensity; and exposing a second UV sensor to the UV light at second intervals to measure illumination intensity of the UV light so as to calibrate the first UV sensor by equalizing the illumination intensity measured by the first UV sensor substantially with the illumination intensity measured by the second UV sensor, wherein each second interval is longer than each first interval.
