  • Publication number: 20240142628
    Abstract: An object detection device includes: a light emitter that emits light; a sensor that generates a first pixel signal by exposure to reflected light according to a combination of emission by the light emitter and first exposure and a second pixel signal by exposure to reflected light according to a combination of the emission and second exposure; and a distance calculator that generates a distance image by ratio operation using the first pixel signal and the second pixel signal. Timing of the first exposure is set to timing during which the sensor is not exposed to reflected waves from an object included in a first section in which a distance from the object detection device is from 0 to a predetermined value. A time difference between the emission and the second exposure is greater than a time difference between the emission and the first exposure.

  • Publication number: 20240132049
    Abstract: A control apparatus for a rotating electric machine is provided. The rotating electric machine includes a moving portion that applies torque to a drive shaft of an internal combustion engine. The control apparatus acquires a rotational frequency signal that is a signal that changes depending on a rotational frequency of the moving portion per unit time. The control apparatus calculates a damping torque that is applied from the moving portion to the drive shaft to suppress vibration during operation of the internal combustion engine. The control apparatus calculates the damping torque based on the rotational frequency signal acquired by the signal acquiring unit in response to the rotating electric machine performing cranking of the internal combustion engine.

  • Patent number: 7571436
    Abstract: The speed of execution of linked programs is improved to the extent possible within the limit of the capacity of memory storing linked programs. As initial settings, all class libraries are set for linking. By this means, all class libraries are linked. Then, a judgment is made as to whether there is overflow of memory storing linked programs. If there is overflow, the maximum value of the number of applications using currently linked class libraries is set in variable N. Then, settings are modified such that class libraries used by N or more applications are not linked, and linking is again performed. If memory overflow does not occur, processing ends.
