Abstract: A communication system includes a management device connected to terminals. The terminal is configured to collect log information, send the log information to the management device, analyze the log information to determine whether an abnormal event occurs in the terminal and determining self-recovery processing, notify the management device of the self-recovery processing for the abnormal event, and execute the self-recovery processing for the abnormal event or recovery processing ordered by the management device. The management device is configured to analyze log information collected from the terminals to determine whether an abnormal event occurs in the terminal, determine recovery processing, receive a notification about self-recovery processing from the terminal, and issue an order to execute the recovery processing for the detected abnormal event to the terminal, depending on whether the notification has been received.

Abstract: It is provided a communication device which transfers a signal, comprising: an arithmetic device configured to execute predetermined processing; a storage device accessible from the arithmetic device; a log collection module configured to collect first type logs from at least one of the communication device or an equipment coupled to the communication device; an alert generation module configured to generate alert when one of the collected the first type logs satisfies a predetermined condition; and a failure cause candidate determination module configured to determine failure cause candidates in response to the generated alert, and output, to the log collection module, an additional log collection request for collecting second type logs in an additional log collection order that is set based on the determined failure cause candidates.

Abstract: A communication device comprising, a local communication unit communicating with an apparatus, a memory unit storing firmware for the apparatus, if the history of activation and deactivation as an external storage terminal by the apparatus is determined to be a predefined sequence, communication device that is not activated as an external storage terminal or that operates in such a way that the firmware is not visible from the apparatus.

Abstract: A mobile apparatus includes a position detection device, and an autonomous mobile body. The position detection device includes input means for inputting route data, a distance sensor, map data, position identification means, and relative route calculation means for calculating a relative position and a relative angle to a position of the target point from the position data and the route data of the mobile body. The autonomous mobile body includes a controller that controls an autonomous travel of the autonomous mobile body itself by using the relative position and the relative angle received from the position detection device as control signals.

Abstract: Position identification means (7) for estimating the position of a mobile robot (1) includes a laser distance sensor (6) that measures a distance from the mobile robot (1) to an object, means for recognizing an object from data of the measured distance from the mobile robot (1) to the object and map data, travel area storage means (12) for storing a travel area of the mobile robot (1), specified area storage means (13) for storing a specified area that is separate from the travel area of the mobile robot (1), and object determination means (14) for determining whether an object is present within the travel area of the mobile robot (1) that is stored in the travel area storage means (12).
