Further, the on-vehicle communication device includes a controller that determines whether to enable or disable a connection to a high-confidential communication channel based on the self-driving level information and the vehicle speed information and/or the current location information.

Abstract: A work assist system includes an automatic driving information acquisition unit configured to acquire automatic driving information containing automatic driving level information representing automatic driving levels from a vehicle capable of automatic driving; a task information storage configured to store task information containing unprocessed tasks to be processed by a driver of the vehicle, groups that classify the tasks according to functions required for processing the tasks, and the automatic driving levels necessary for processing the tasks using the functions corresponding to the groups; and a task extractor configured to extract a task that is processable by the driver in the vehicle based on the automatic driving information acquired by the automatic driving information acquisition unit and the task information stored in the task information storage.

Abstract: A camera thumbnail image acquisition unit acquires a first thumbnail image from a camera. A distribution server thumbnail image acquisition unit acquires a second thumbnail image from a distribution server. A thumbnail image selection unit selects one of the first thumbnail image and the second thumbnail image as a thumbnail image that should be displayed. A camera information acquisition unit acquires camera information including streaming execution information indicating whether the camera is streaming. The thumbnail image selection unit refers to the streaming execution information to select the second thumbnail image as the thumbnail image that should be displayed when the camera is streaming and to select the first thumbnail image as the thumbnail image that should be displayed when the camera is not streaming.

Abstract: A clock signal generating apparatus has a phase-lock loop circuitry. A phase comparator compares, in phase, an input digital signal with a clock signal that has already been generated. A differential amplifier amplifies the difference between the output of the phase comparator and a reference voltage. A clock signal generator generates a clock signal to be supplied to the phase comparator, based on the amplified difference. An accumulator accumulates an amount of errors of the input digital signal. A voltage generator generates a reference voltage to be supplied to the differential amplifier within a range from a predetermined minimum voltage to a predetermined maximum voltage. The level of the generated reference voltage is adjusted according to the output of the accumulator. The operating point of the clock signal generator is controlled by the level-adjusted reference voltage.

Abstract: A network connects first, second, and third apparatuses. The first apparatus generates a first list of contents represented by data stored therein. The second apparatus generates a second list of contents represented by data stored therein. The first apparatus gets the second list of contents from the second apparatus, and combines the first list of contents and the second list of contents into a third list of contents. The second apparatus gets the first list of contents from the first apparatus, and combines the first list of contents and the second list of contents into a fourth list of contents which is equal to the third list of contents. The third apparatus refers to one of (1) the third list of contents which is generated by the first apparatus and (2) the fourth list of contents which is generated by the second apparatus.
