    摘要： A method is provided. A command to correspond to a target speed of a motor is received. A rotational speed of the motor is measured, and a brake-to-off ratio for a braking interval is calculated based at least in part on the rotation speed, the target speed, a braking parameter. An off state for an inverter that is coupled to motor is induced during an off portion of the braking interval, and a brake signal is applied to the inverter during a braking portion of the braking interval.

    摘要： A mobile electronic device 10 includes a projector 34, a camera 36, and a processing unit 22. The projector 34 projects an image, and the camera 36 captures the image projected by the projector 34. Based on first image information for causing the projector 34 to project a predetermined image and second image information obtained by capturing the image projected by the projector 34 based on the first image information by the camera 36, the processing unit 22 determines whether the projector 34 projects the predetermined image. When determining that the projector 34 fails to project the predetermined image, the processing unit 22 suppresses output of the projector 34 for projecting the image.

    摘要： According to an aspect, an image projecting apparatus that projects an image includes a light source, a light emitting port, an emitting unit, and a control unit. The emitting unit causes the light emitted from the light source to be emitted from the light emitting port in such a manner that an emission direction of the light emitted from the light source can be varied. The control unit controls the light source and the emitting unit to switch between a first projection mode and a second projection mode. When the image projecting apparatus is placed on a horizontal plane, the emission direction is a front direction of the light emitting port or obliquely upward with respect to the horizontal plane in the first projection mode, and the emission direction is obliquely downward with respect to the horizontal plane in the second projection mode.

    摘要： An object is to provide a mobile electronic device with high operability and high safety. The mobile electronic device includes an image projector that projects an image, a control unit that controls a projection operation by the image projector, and a cabinet that supports the image projector and the control unit. The control unit can select a first mode and a second mode, and controls an operation of the image projector, when the first mode is selected, in a condition different from that when the second mode is selected. The object is thereby solved.
