A device power supply system is applied to a building including a recessed space that is formed to be recessed with respect to a wall surface of a living space and is opened toward the living space and is for supplying electric power to a device. The device power supply system includes: a device arrangement portion that is provided in the recessed space and in which the device is to be disposed; and a power transmitter that transmits electric power to be supplied to the device disposed in the device arrangement portion as microwaves, and the power transmitter is disposed on a peripheral portion of the recessed space or at an inner side of the peripheral portion, and a transmission direction of the microwaves is set to a direction intersecting a depth direction of the recessed space.

In a door control system, a reservation signal is transmitted when a user operates a mobile device and reserves opening a door, a control device transmits a reservation acceptance signal and starts transmitting a response request signal upon receipt of the reservation signal. When the mobile device receives the reservation acceptance signal, a mobile device memory stores information indicating that the reservation is accepted and authorized and a notification unit notifies the user of authorization. When the mobile device receives the response request signal, the mobile device transmits a response signal including the stored information indicating authorization. When the control device receives the response signal including the information indicating authorization in response to the response request signal, a controller performs at least one of unlocking or opening the door.

A vehicle control device includes a plurality of LF transmitters transmitting response request signals that reach an area around a vehicle and an interior of a vehicle chamber, and a UHF receiver receiving a signal transmitted from a portable machine. The portable machine includes an LF receiver receiving the response request signal and a UHF transmitter transmitting a response signal. The LF receiver in the portable machine has a reception region in which the response request signals transmitted from at least two of the LF transmitters are receivable when the portable machine approaches the vehicle. Door locking/unlocking is permitted if the LF receiver in the portable machine receives the response request signals transmitted from at least two of the LF transmitters within a predetermined time period. In contrast, door locking/unlocking is inhibited if the LF receiver receives the response request signal transmitted from one of the LF transmitters.
