Abstract: According to one embodiment, in an X-ray computed tomography apparatus including a gantry unit including an X-ray tube and an X-ray detector, a bed unit, and a console, the X-ray computed tomography apparatus includes a storage unit, a power supply unit, and a power supply control unit. The storage unit stores examination schedule data of the X-ray computed tomography. The power supply unit selectively operates between an active mode of supplying power to at least one of the gantry unit, the bed unit, and the console and a standby mode of stopping supplying power to at least one of the bed unit and the gantry unit and supplying, to the console, power smaller than power supplied in the active mode. The power supply control unit controls switching from the active mode to the standby mode based on the examination schedule data.

Abstract: A mobile phone handset includes a mode switching unit and a configuration detection sensor, so that the operating mode of the mobile phone handset can be switched. The mode switching unit has a switching program installed, and is a computer for executing a prescribed process in accordance with the switching program when a signal is input from the configuration detection sensor. The configuration detection sensor is a sensor for detecting the configuration of the mobile phone handset, and for example may use an angular sensor for detecting the relative angle about a rotation axis between a first casing and a second casing.
