  • Publication number: 20210232340
    Abstract: A drive recorder transmits, to a server device, a moving image file showing status of surroundings of a vehicle at the time of generation of a large acceleration. The server device determines whether overwrite prohibition is to be designated for the moving image file that shows surroundings of the vehicle at the time of an occurrence of an event, based on the moving image file. The drive recorder designates, based on a determination result, overwrite prohibition for a piece of video data showing surroundings of the vehicle at the time of and/or before and after the occurrence of the event, and counts the number of pieces of video data for which overwrite prohibition is designated.

  • Publication number: 20210206269
    Abstract: A device control system includes a first input device and a gaze detector. The first input device allows a command to be entered with respect to a target device selected from one or more devices. The gaze detector detects a user's gaze direction. The gaze detector determines, based on the gaze direction detected by the gaze detector, one device, selected from the one or more devices, to be the target device. A gaze detector makes the target device change, based on the gaze direction detected by the gaze detector, the type of processing to be performed in accordance with the command entered through the first input device.

  • Patent number: 9828612
    Abstract: A method is provided for the production of alcohol from trees, the method comprising a step of treating a subject tree with mother cell lyases formed through cytolysis associated with sporulation of spore-forming aerobic bacteria, thereby degrading said tree into a powdery state and obtaining a tree degradation product; a step of sterilizing said tree degradation product; a step of treating said sterilized tree degradation product with a koji fungus (Aspergillus oryzae) thereby carrying out a primary fermentation; a step of adding a yeast to the fermentation broth obtained by said primary fermentation thereby carrying out a secondary fermentation; and a step of filtering the fermentation broth obtained by said secondary fermentation, wherein said mother cell lyases are obtained by culturing said spore-forming aerobic bacteria, subjecting the resultant culture medium to a starvation state, thereby converting said bacteria into endospores, and removing impurities including said endosporic bacteria from said cul
