A diagnosis system diagnoses the integrity of an opening/closing device capable of opening and closing by driving a motor. A driving current acquisition unit acquires a driving current of the motor. A diagnosis unit defines a current waveform from a temporal change of the driving current acquired by the driving current acquisition unit and diagnoses the integrity of the opening/closing device based on the current waveform.

Diagnosis system and diagnosis method for opening/closing device

An inspection method according to the present disclosure includes a step of mounting an ultrasonic probe, a step of mounting a pulser receiver, a step of causing the ultrasonic probe to transmit ultrasonic waves, a step of causing the ultrasonic probe to receive a reflected wave of the ultrasonic waves reflected by the wind turbine blade, a step of causing the pulser receiver to acquire reflected-wave data, a step of causing the pulser receiver to wirelessly transmit the reflected-wave data, a step of causing at least one of antennas to receive the wirelessly transmitted reflected-wave data, and a step of causing an information processing device electrically connected to the at least two antennas to perform information processing on the reflected-wave data.

A toll collection system includes: a vehicle detector which detects entry of a vehicle to the lane; a vehicle type identification unit which identifies the vehicle type of the vehicle at a stage before the vehicle is detected by the vehicle detector; and a position measurement unit which measures, on the basis of a position measurement signal obtained by receiving, through a predetermined position measurement antenna, radio waves transmitted by the on-board unit after the vehicle is detected by the vehicle detector, the position of the on-board unit which has transmitted the radio waves. The position measurement unit is configured to measure the position of the on-board unit on the basis of an angle of arrival of the radio waves measured on the basis of the position measurement signal, and an installation height of the on-board unit estimated from a vehicle type identification result of the vehicle.

Toll collection system, position measurement method, and program

In a location detecting system, an on-vehicle device is provided at each vehicle a location detecting unit detecting a location of the vehicle, a communication unit, and a CPU unit controlling the location detecting unit and the communication unit. Each of the on-vehicle devices includes a GPS trajectory information processing unit acquiring GPS trajectory information of each of the vehicles, the communication unit broadcasts requests for the GPS trajectory information, the communication units of other vehicles transmit the held GPS trajectory information to the communication unit of one vehicle when a distance to the vehicle is less than a predetermined value, the GPS trajectory information processing unit passes the GPS trajectory information from the other vehicles to the location detecting unit, and the location detecting unit of the vehicle outputs the location information of the vehicle based on the GPS trajectory information.

Location detecting system and location detecting method of the location detecting system

A vehicle position measurement method includes a process of determining whether or not position information of an own vehicle is able to be acquired with predetermined quality from the outside, a process of acquiring position information of a nearby vehicle present in an area in which the own vehicle is capable of acquiring information when the position information is determined not to be able to be acquired with the predetermined quality, and a process of replacing the position information of the own vehicle with the acquired position information of the nearby vehicle.
