Abstract: A device management system includes: a server; base stations for long-distance wireless communication; and a device that communicatively connect to one of the base stations and that each sequentially transmit, to the server via the one base station, operation information indicating the current operation state of the device. Upon sequentially receiving the operation information, each of the base stations sequentially transmits, to the server, unique information unique to the base station together with the sequentially received operation information. The server sequentially receives, and sequentially stores in association with each other, the operation information and the unique information. When first and second unique information received at first and second times, respectively, are different, the server separately manages first operation information received in a first period ending at the first time and second operation information received in a second period starting at the second time.

Abstract: A video display apparatus includes: a tone mapping processor that performs a tone mapping process of converting a luminance of a video by using conversion characteristics according to a maximum luminance of the video; and a display that displays the video that has undergone the tone mapping process. The tone mapping processor switches between a first tone mapping process of dynamically changing the conversion characteristics according to a time-depend change in the maximum luminance of the video and a second tone mapping process that is performed using constant conversion characteristics irrespective of the time-depend change in the maximum luminance of the video. When the tone mapping process used is switched from the second tone mapping process to the first tone mapping process, the conversion characteristics used is changed gradually or stepwise from the constant conversion characteristics to dynamically changing conversion characteristics over a plurality of frames.

Abstract: When a braking request is made while a SOC recovery switch is turned off, regeneration driving of a rear wheel motor is prohibited. In this case, a front wheel motor, the rear wheel motor, and an oil hydraulic brake device are controlled such that requested braking torque is exerted on a vehicle with regenerative driving of the front wheel motor and without regenerative driving of the rear wheel motor. When the braking request is made while the SOC recovery switch is turned on, the regeneration driving of the rear wheel motor is permitted. In this case, the front wheel motor, the rear wheel motor, and the oil hydraulic brake device are controlled such that the requested braking torque is exerted on the vehicle with regenerative driving of the front wheel motor and the rear wheel motor.
