TERMINAL DEVICE, CONTROL DEVICE, FAULT DIAGNOSIS SYSTEM, AND FAULT DIAGNOSIS METHOD
First Claim
1. A terminal device which performs short-range wireless communication with an external control device and the faults of which are diagnosed by the control device,the terminal device comprising:
- a first power supply unit that supplies electric power;
an antenna unit that transmits and receives short-range radio waves to and from the control device;
a second power supply unit that induces electric power from the radio waves received by the antenna unit and supplies the induced electric power;
a storage unit that operates after receiving the supply of electric power from the second power supply unit;
a control unit that operates after receiving the supply of electric power from the first power supply unit and stores in the storage unit first information indicating whether the control unit is in an active state or an idle state; and
an information acquiring unit that operates after receiving the supply of electric power from the second power supply unit, acquires second information indicating whether electric power is supplied from the first power supply unit, acquires the first information from the storage unit, and transmits the acquired first and second information to the control device via the antenna unit.

Abstract
A state updating unit updates first information stored in a storage unit whenever the state of a control unit transitions from an idle state to an active state or from the active state to the idle state. A second power supply unit induces electric power from radio waves received by the antenna unit. An information acquiring unit operates after receiving the supply of electric power from the second power supply unit, acquires second information indicating whether electric power is supplied from the first power supply unit, acquires the first information from the storage unit, and transmits the acquired first and second information to the control device. A diagnosing unit diagnoses faults in the terminal device based on the first and second information transmitted from the information acquiring unit of the terminal device.
