An address assignment device is provided to a master station involved in a communication network in which the master station and a plurality of slave stations are connected via a communication line. A provisional address assignment unit registers with a provisional address table, a provisional address of each slave station, and a distance measurement result of a distance between the master station and each slave station. A duplicate address detecting unit requests each of equidistant slave stations to measure a distance to a neighboring slave station, and registers provisional addresses of the equidistant slave stations and a neighboring distance result with the provisional address table. A slave station address assignment unit analyzes a connecting configuration in the communication network, and assigns a slave station address for the provisional address of each slave station with using address information.

A driving mechanism controller included in a capturing device causes one or more driving mechanisms to spread a tethering member having an elongated shape to the outside of a housing by a target spread length. The driving mechanism controller, when an artificial space object is located in the area surrounded by the tethering member, causes the one or more driving mechanisms to retract the tethering member to the inside of the housing until at least a part of the tethering member comes into contact with the artificial space object. The tethering member is stable in a first shape having a curved section orthogonal to a linear extending direction of the tethering member.

A power supply includes a DC-to-DC converter that charges a storage battery and a controller that controls the charging of the storage battery. The power supply has operating modes including a constant-voltage mode where the storage battery is charged at a constant voltage and a current-limiting mode where the storage battery is charged with an upper limit specified for charging current for the storage battery. The controller includes a first control block that controls the constant-voltage mode, a second control block that controls the current-limiting mode, and a conduction ratio command computer that computes a conduction ratio command. The second control block includes a primary lag block that allows a signal to go through for input to the conduction ratio command computer upon an operating mode switchover from the constant-voltage mode to the current-limiting mode.

A communication system that can reduce latency while preventing reduction in a transmission rate. An eNB communicates with a UE #1 using a self-contained subframe including a first downlink signal (DL #1) and a first uplink signal (UL #1), and with a UE #2 using a self-contained subframe including a second downlink signal (DL #2) and a second uplink signal (UL #2). The self-contained subframe for the UE #1 includes a first gap duration (Gap #1) during which neither the DL #1 nor the UL #1 is transmitted, between transmission durations of the DL #1 and the UL #1. The self-contained subframe for the UE #2 includes a second gap duration (Gap #2) during which neither the DL #2 nor the UL #2 is transmitted, between transmission durations of the DL #2 and the UL #2. The Gaps #1 and #2 are set to each UE.

To provide a controller for AC rotary electric machine which can suppress the increase in the unwanted sound while reducing noise. A controller for AC rotary electric machine switches n pieces of zero phase candidate voltage values in order for every switching period and calculate as a zero phase voltage value; by defining a deviation between the zero phase voltage value and a time lag zero phase voltage value delaying by a j times value of the switching period, as a zero phase time lag deviation value; j is a natural number which minimizes a difference between a half period of a mechanical resonance period, and the j times value of switching period; an effective value of the zero phase time lag deviation value becomes small, compared with an effective value of AC component of the zero phase voltage value.

An information collection unit collects information indicating a driving operation of a vehicle by a driver and a state of the vehicle changed by the driving operation, and outputs, among the collected information, information in a period from a start point at which a driving operation contributing to stop of the vehicle is performed to a stop start point in a stop state where a stop time of the vehicle continues for a predetermined time or more, as driving operation information. A state estimation unit acquires driver state information indicating a state of the driver from a learned learner on which machine learning has been performed so as to output the driver state information when the driving operation information is input, by inputting the driving operation information output from the information collection unit to the learner and performing arithmetic processing of the learner.
