Assignee: nan
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The electronic device of claim 1, further comprising:
a signal processing unit comprising a second FET, a second diode that is electrically connected with the state detecting unit and is electrically connected with a gate of the second FET, and a second photo coupler electrically connected with a drain of the second FET,
wherein the second FET is turned on in response to receiving by using the gate of the second FET, from the state detecting unit through the second diode, a second signal for indicating that the state of the user device is switched from the first designated state to the second designated state,
wherein a LED of the second photo coupler is turned on based on turning on the second FET,
wherein a transistor of the second photo coupler is turned on based on turning on the LED of the second photo coupler,
wherein a state of a third signal transmitted from the signal processing unit to the control unit is switched from a first state to a second state based on turning on the transistor of the second photo coupler, and
wherein the control unit is configured to switch, in response to the third signal switched from the first state to the second state, the state of the first signal from the first state to the second state.
