Electric device and tire condition monitoring apparatus
First Claim
1. An electric device comprising:
- a battery having a pair of electrodes, each of the electrodes including a current collector and an active material layer;
a load device driven by the battery; and
a refresh circuit that performs refresh, in which the refresh circuit forcibly supplies an electric current between the electrodes, thereby removing adhering matter from the electrodes.

Abstract
A tire condition monitoring apparatus having a transmitter and a receiver is disclosed. The transmitter incorporates a battery having a positive electrode and a negative electrode. The transmitter wirelessly transmits a signal including data representing the condition of a tire of a vehicle using electromotive force produced by the battery. The receiver receives the signal from the transmitter and processes the signal. The transmitter includes a refresh circuit that performs refresh by forcibly supplying an electric current to the positive and negative electrodes of the battery. The transmitter measures the electromotive force of the battery after such refresh. If the electromotive force of the battery has not been recovered, the transmitter sends a notification signal indicating insufficiency of the electromotive force of the battery to the receiver. In response to the notification signal, the receiver announces insufficient capacity of the battery to the driver of the vehicle by means of a warning device.

10. A tire condition monitoring apparatus comprising:
-
a transmitter that is arranged in a tire of a vehicle, detects a condition of the tire, and transmits a signal indicating the detected condition of the tire; and a receiver that is mounted in a body of the vehicle and receives the signal indicating the condition of the tire, wherein the transmitter includes; a battery having a pair of electrodes, each of the electrodes including a current collector and an active material layer; a load device that detects the condition of the tire and transmits the signal, the load device being driven by the battery; and a refresh circuit that performs refresh, in which the refresh circuit forcibly supplies an electric current between the electrodes, thereby removing adhering matter from the electrodes. - View Dependent Claims (11, 12)
