Abstract: A vehicle control device configured to perform control related to pickup and delivery by a vehicle. The vehicle is movable forward bi-directionally and includes package compartments on first and second sides. The vehicle control device is configured to perform operations including: acquiring position information of a target user point; acquiring position information of a target package compartment for storing a package to be delivered or picked up with respect to an advancing direction in which the vehicle travels toward the target user point; and outputting an instruction to reverse the advancing direction of the vehicle to a vehicle controller configured to perform traveling control of the vehicle in a case where a side of a side surface where the target package compartment is positioned and a side of the target user point with respect to the advancing direction of the vehicle do not coincide with each other.

Abstract: According to an embodiment, a key exchange system includes: a key generation device configured to generate a key based on quantum key exchange or post-quantum key exchange; a network device configured to perform encrypted communication with another network device by using the key; and an intermediate server deployed between the key generation device and the network device. The intermediate server includes: a state monitoring unit configured to transmit a state monitoring request to the key generation device at each predetermined time; a notification unit configured to give a push notification of key information included in a response to the state monitoring request, to the network device, when the response is received; and a key exchange unit configured to start key exchange between the network device and the key generation device in response to a request from the network device having received the push notification of the key information.

Abstract: A vehicle operation management system includes a communication terminal and a plurality of vehicles that communicates with the terminal, and is capable of autonomously driving. The vehicles include a first vehicle and a second vehicle. In a boarding area, when the first vehicle is at a leading portion in a file, the second vehicle is at a next position in the file, and one boarding request is made from the terminal, the first notification unit in the first vehicle notifies that the first vehicle is available for boarding, and the second notification unit in the second vehicle does not notify that the second vehicle is available for boarding. When the first vehicle is at the leading portion and the second vehicle is located at the nest position, and at least two boarding requests are made, the first and second notification units notify that the first and second vehicles, respectively, are available for boarding.

Abstract: In a correlation circuit 103, a correlation value is obtained by despreading processing of a reception signal. The above correlation value is sent to a cell detection circuit 104 and a cell monitoring circuit 105. The above results of cell detection and cell monitoring are sent to a cell management table 106 for classification and management of cells. A management circuit 107 changes the cycle for cell monitoring/cell detection according to various kinds of events, and, then, gives an instruction for cell detection and cell monitoring at the changed cycle to the cell detection circuit 104 and the cell monitoring circuit 105.

Abstract: A radio-link continuity keeping equipment in a cellular telephone mobile station includes a removable battery, a backup memory for storing therein a channel connection information when the battery is removed during a conversation mode, a timer for measuring an elapsed time after the battery is removed during the conversation mode until the battery is again set, and a device for judging whether or not the elapsed time measured by the timer is within a predetermined time and when the elapsed time is within the predetermined time, for restoring voice channel on the basis of the channel connection information stored in the backup memory. The timer is provided for measuring a time during which a battery is detached, i.e., the elapsed time after the battery is detached until a new battery is again set. When the measured time of the timer is shorter than the predetermined time, a voice channel is restored on the basis of the channel connection information stored in the backup memory.
