Abstract

An auxiliary power receiving device includes a power receiving unit, a notification unit, and a notification controlling unit. The power receiving unit receives power from a power transfer signal, which is used to supply power from a power transmitting device to a power receiving device. The notification unit may be provided on a main surface of a plate-shaped member. The notification controlling unit controls a notification performed by the notification unit in accordance with a power reception condition of the power transfer signal at the power receiving unit.

First claim

What is claimed is:

1. An auxiliary power receiving device, comprising:
at least one power receiving unit configured to receive power from a power transfer microwave signal, which is used to supply power from a power transmitting device to a power receiving device;
at least one notification unit configured to be provided on a main surface of a plate-shaped member; and
a notification controlling unit configured to control a notification performed by the notification unit in accordance with a power reception condition of the power transfer microwave signal at the power receiving unit, wherein
the at least one notification unit includes a plurality of notification units,
each notification unit of the plurality of notification units:
is provided on the main surface of the plate-shaped member, and
includes a light emitting unit,

the at least one power receiving unit includes a plurality of power receiving units,
each power receiving unit of the plurality of power receiving units is provided at a position corresponding to a respective position at which at least one respective notification unit of the plurality of notification units is provided; and
the notification controlling unit is configured to, for each power receiving unit,
determine whether power is received at the power receiving unit, and in response to determining that power is received, turn on the light emitting unit of the at least one respective notification unit provided at the respective position corresponding to the position of the power receiving unit at which the power transfer microwave signal is received to notify a user that the power transfer microwave signal has been received by the power receiving unit.

2. The auxiliary power receiving device according to claim 1 , wherein the notification controlling unit is configured to
determine whether the power transfer microwave signal reflected by a metal reflection member provided on a transmission path of the power transfer microwave signal is received at at least one of the plurality of power receiving units,
in response to determining that the reflected power transfer microwave signal is received, turn on the light emitting unit of the at least one notification unit located at positions corresponding to positions of the at least one of the plurality of power receiving units at which the reflected power transfer microwave signal is received to notify a user that the power transfer microwave signal has been received by the at least power receiving unit.

3. The auxiliary power receiving device according to claim 1 , wherein the at least one notification unit is provided on a surface of a structure that is configured to be installed so as to extend vertically from the ground.

4. The auxiliary power receiving device according to claim 1 , wherein the notification controlling unit is configured to change a notification mode of each notification unit of the plurality of notification units according to a strength of the power transfer microwave signal received by the corresponding at least one power receiving unit.

5. The auxiliary power receiving device according to claim 1 , wherein the plurality of notification units are provided at intervals on the main surface of the plate-shaped member.

6. The auxiliary power receiving device according to claim 1 , wherein each power receiving unit includes a power receiving antenna which receives power from the power transfer microwave signal.

7. The auxiliary power receiving device according to claim 1 , the light emitting units being at least one light emitting diode.

8. The auxiliary power receiving device according to claim 1 , further comprising at least one processor configured as the notification controlling unit.

9. The auxiliary power receiving device according to claim 1 , wherein
each power receiving unit includes a power receiving antenna which receives power from the power transfer microwave signal;
each of the light emitting units is at least one light emitting diode; and
further comprising at least one processor configured as the notification controlling unit.

10. The auxiliary power receiving device according to claim 1 , wherein the notification controlling unit is further configured to, for each power receiving unit,
in response to determining that power is not received, turn off the light emitting unit of the at least one respective notification unit provided at the respective position corresponding to the position of the power receiving unit at which the power transfer microwave signal is not received.
