  • Patent number: 11178137
    Abstract: A data communication system has an IoT device, an information processing device capable of performing communication with the IoT device, and a server capable of performing communication with the IoT device and the information processing device. When a coupling request from the IoT device is received, the information processing device requests the server for a tentative common key which is temporarily valid. When a request for a tentative common key from the information processing device is received, the server generates a tentative common key and transmits the tentative common key to the information processing device. The information processing device transmits the received tentative common key to the IoT device, and the IoT device and the server perform authentication by using the tentative common key.

  • Publication number: 20210342630
    Abstract: Techniques are disclosed for using and training a descriptor network. An image may be received and provided to the descriptor network. The descriptor network may generate an image descriptor based on the image. The image descriptor may include a set of elements distributed between a major vector comprising a first subset of the set of elements and a minor vector comprising a second subset of the set of elements. The second subset of the set of elements may include more elements than the first subset of the set of elements. A hierarchical normalization may be imposed onto the image descriptor by normalizing the major vector to a major normalization amount and normalizing the minor vector to a minor normalization amount. The minor normalization amount may be less than the major normalization amount.

  • Publication number: 20210155456
    Abstract: An elevator includes a compensating sheave, a compensating rope, a guide, a holder, a driver, a lateral vibration detector, and driver controller. The compensating rope is looped around the compensating sheave to be bent back upward in a hoistway, and has a first end connected to a car and a second end connected a counterweight, the compensating rope suspended from the car and the counterweight. The guide guides the compensating sheave in a vertically displaceable manner. The holder holds the guide to be displaceable in a horizontal direction. The driver drives the holder in the horizontal direction. The lateral vibration detector detects lateral vibration of the compensating rope. The driver controller controls the driver based on a result of detection by the lateral vibration detector and accordingly drive the holder in the horizontal direction so as to dampen lateral vibration of the compensating rope.
