Abstract: A control unit of a vehicle power control apparatus performs an operation described below. The control unit fluctuates a voltage of an alternating-current power output from a discharging terminal with a power supplier when the control unit detects that a receiving terminal of an alternating-current load or a charging terminal is connected to the discharging terminal, or that a supply terminal of an alternating-current power supply or the discharging terminal is connected to the charging terminal. Also, the control unit directs a notifying portion to perform a notifying operation when the control unit detects that a voltage of alternating-current power input to the charging terminal is fluctuating in the same manner that a voltage of alternating-current power output from the discharging terminal is fluctuating.

Abstract: Incident signal beam pulses are transmitted by an on-state region, and an optical path for the signal beam pulses is spatially switched in an optical switch. Signal beam pulses transmitted by the on-state region of the optical switch are detected at a pixel corresponding to a transmitting region of a photo-detector equipped with a plurality of pixels. A timing computation unit acquires position information of a pixel at which a predetermined signal beam pulse has been detected, on the basis of a result of the detection conducted by the photo-detector, and computes timing of arrival of a predetermined signal beam pulse at the optical switch on the basis of the position information of the pixel and time when a region corresponding to the pixel is brought to an on-state.

Abstract: A coordinate reader comprises first and second conductor loops each having an electrical conductor so that electrical conductors of the respective conductor loops are juxtaposed on an electrically insulating board, a cosine function generator connected to one of the first and second conductor loops, a sine function generator connected to the other of the first and second conductor loops, a cursor incorporating a magnetic flux detecting coil for detecting magnetic fluxes generated in the conductor loops excited by the cosine and sine function generators, and a processor. The processor processes and controls operations of the aforementioned components to detect coordinates of the cursor.
