Abstract
An electronic apparatus includes: a power reception section configured to receive power transmitted with use of a magnetic field or an electric field; a secondary battery; a charging section configured to perform charging to the secondary battery, based on received power received by the power reception section; a load configured to perform predetermined operation, based on supplied power; and a control section configured to forcibly set a power path on a preceding side of the load to a predetermined state when the load is activated in the charging to the secondary battery.
Claims21
(canceled)
An electronic apparatus comprising:
- power reception circuitry configured to receive power transmitted via a magnetic field or an electric field;
- a battery;
- charging circuitry configured to perform charging to the battery based on the power received by the power reception circuitry;
- a state informing section configured to inform outside of an apparatus state of itself, the state informing section including a light emitting element;
- a load configured to perform a predetermined operation;
- control circuitry configured to:
- control the charging circuitry and the load;
- detect whether the load is activated or not in the charging to the battery;
- and
- in a case that it is detected that the load is activated in the charging to the battery, forcibly fix an informing mode by the state informing section to a mode of informing outside of the apparatus state irrespective of presence of a surplus power, the surplus power being obtained by subtracting a power consumed by the load from the power received by the power reception circuitry,
- wherein the light emitting element is connected to the load and connected to a first switching element provided on a power supply path.
The electronic apparatus according to claim , wherein a lighting section for informing outside of the apparatus state is fixed to a lighting state in the mode of informing outside of the apparatus state.
A feed system comprising:
- one or more electronic apparatuses;
- and
- a feed unit configured to transmit power to the electronic apparatuses with use of a magnetic field or an electric field,
- wherein each of the electronic apparatuses comprises:
- power reception circuitry configured to receive power transmitted via a magnetic field or an electric field;
- a battery;
- charging circuitry configured to perform charging to the battery based on the power received by the power reception circuitry;
- a state informing section configured to inform outside of an apparatus state of itself, the state informing section including a light emitting element,
- a load configured to perform a predetermined operation;
- control circuitry configured to:
- control the charging circuitry and the load;
- detect whether the load is activated or not in the charging to the battery;
- and
- in a case that it is detected that the load is activated in the charging to the battery, forcibly fix an informing mode by the state informing section to a mode of informing outside of the apparatus state irrespective of presence of a surplus power, the surplus power being obtained by subtracting a power consumed by the load from the power received by the power reception circuitry,
- wherein the light emitting element is connected to the load and connected to a first switching element provided on a power supply path.
