  • Publication number: 20240157245
    Abstract: There is provided an information processing apparatus and resources for automatically recognizing an allowed region in order to eliminate time and effort required every time the allowed region is to be designated. The information processing apparatus includes a sorting section, a region identifying section, and an allowed region determining section. The sorting section sorts multiple planes included in space information representing an object existing in a three-dimensional space by use of the multiple planes, into at least a plane corresponding to a base and a plane corresponding to an obstacle. The region identifying section calculates a base region pertaining to the plane corresponding to the base and an obstacle region pertaining to the plane corresponding to the obstacle. The allowed region determining section calculates, on the basis of the base region and the obstacle region, an allowed region in which a target object existing in the three-dimensional space is allowed to be positioned.

The common mode choke coil includes an annular core, two windings wound around the core, and an annular conductor that covers the two windings. The conductor is divided into a first metal plate and a second metal plate, which are combined to form an annular shape such that induced current flows in a circumferential direction of the conductor so as to hinder changes in leakage magnetic flux from the core. The second metal plate is thermally connected to the housing. The first metal plate is thermally connected to the second metal plate. At least one of an electrical resistance value or a thermal resistance value in a current path of the induced current is lower in the second metal plate than in the first metal plate.

  • Patent number: 11811348
    Abstract: An inverter controller is used to control an inverter circuit, which drives a vehicle on-board electric motor using a vehicle on-board electricity storage device. A rotation controlling unit of the inverter controller executes a process that derives two-phase voltage command values based on an external command value delivered from an external device and an actual rotation speed, and a process that derives three-phase voltage command values based on the two-phase voltage command values. In a case in which a voltage utilization factor is less than or equal to a utilization factor threshold, the rotation controlling unit derives, by switching at a switching period, sets of three-phase voltage command values of which the line voltages of the vehicle on-board electric motor are the same and the variation ranges are different.

  • Publication number: 20230318500
    Abstract: A controller uses a differential pressure between a discharge pressure and a suction pressure to estimate an execution time of braking control needed to fix a position of a rotor at a specific angle. Further, the controller executes the braking control by the estimated execution time. This prevents the controller from unnecessarily continuing to execute the braking control.
