  • Patent number: 12195304
    Abstract: A break detection device includes a sensor, an abnormal variation detection unit (22), a storage unit (20), an arithmetic unit (23), and a break determination unit (24). The arithmetic unit (23) increases a determination score when the abnormal variation detection unit (22) detects occurrence of an abnormal variation when a car (1) passes a position stored in the storage unit (20). The arithmetic unit (23) decreases the determination score when the abnormal variation detection unit (22) does not detect the occurrence of the abnormal variation when the car (1) passes the position. The break determination unit (24) determines whether or not a broken portion is present in a rope on the basis of the determination score.

  • Patent number: 12110211
    Abstract: A break detection device includes an extraction unit (22), an extraction unit (23), a detection unit (24), and a determination unit (26). The extraction unit (22) extracts, from an output signal from a sensor, a vibration component in a specific frequency band. The extraction unit (23) attenuates, from the vibration component extracted by the extraction unit (22), a steady vibration component and a progressively increasing vibration component to extract a determination signal. The detection unit (24) detects, on the basis of the determination signal, occurrence of an abnormal variation in the output signal from the sensor. The determination unit (26) determines whether or not a rope has a broken portion.

  • Patent number: 11182949
    Abstract: A method of facilitating an interactive rendering of a computer image at a remote computer includes: at a first time, obtaining first information of the image, including pixel information of the image at the first time; and, at a second time after the first time, obtaining second information of the image including pixel information of the image at the second time. Delta pixel information is generated by comparing the pixel information of the first information with the pixel information of the second information, to include one or more portions of the pixel information of the second information updated since the first information was obtained, and to exclude one or more portions of the pixel information of the second information unchanged since the first information was obtained. The method further includes: transmitting the delta pixel information in a lossless format to a front-end client to enable reconstruction of the second information.
