Abstract
An electronic unit includes an electricity reception section that receives power transmitted using one of a magnetic field and an electric field, a secondary battery that is charged based on a received power received by the electricity reception section, and a state notification section that provides notification to outside as to a state of its own unit. A charging period during which the secondary battery is charged based on the received power and a non-charging period are set in a time-divisional manner. The state notification section notifies of the unit state based on the received power in both of the charging period and the non-charging period.
Claims11
An electronic unit, comprising:
- an electricity reception section configured to receive a power transmitted via one of a magnetic field or an electric field;
- a secondary battery;
- a charging section configured to store, in a charging period, the received power in the secondary battery;
- and
- a state notification section configured to:
- notify, in the charging period, information of the electronic unit to an outside environment of the electronic unit by utilization of the received power from the electricity reception section;
- and
- notify, in a non-charging period, the information of the electronic unit to the outside environment by utilization of the stored power in the secondary battery.
A power feeding system, comprising:
- at least one electronic unit;
- and
- a power feeding unit configured to transmit a power to the at least one electronic unit via one of a magnetic field or an electric field,
- wherein each electronic unit of the at least one electronic unit includes:
- an electricity reception section configured to receive the power;
- a secondary battery;
- a charging section configured to store, in a charging period, the received power in the secondary battery;
- and
- a state notification section configured to:
- notify, in the charging period, information of the electronic unit to an outside environment of the electronic unit by utilization of the received power from the electricity reception section;
- and
- notify, in a non-charging period, the information of the electronic unit to the outside environment by utilization of the stored power in the secondary battery.
