Assignee: WISTRON NEWEB CORPORATION
Field: Control (Instruments)
Classification: CPC F  G  H | IPC F  G  H

Claim 2:
3. The remote-control system according to claim 2, further comprising a first ultra-wideband transceiver and a second ultra-wideband transceiver, wherein the first wireless communication circuit is a first BLUETOOTH circuit, the first ultra-wideband transceiver is electrically connected to the first BLUETOOTH circuit, the second wireless communication circuit is a second BLUETOOTH circuit, and the second ultra-wideband transceiver is electrically connected to the second BLUETOOTH circuit; wherein, when the received signal strength indication is greater than or equal to the strength threshold, the first BLUETOOTH circuit is configured to have the first ultra-wideband transceiver switched from a sleep state to a working state, and the second BLUETOOTH circuit is configured to have the second ultra-wideband transceiver switched from a sleep state to a working state; wherein the second ultra-wideband transceiver that is in the working state measures a distance between the remote controller and the controlled device, and determines whether or not the distance is within a preset distance range; wherein, when the distance is within the preset distance range, the second BLUETOOTH circuit detects the operational state of the controlled device and sends the control command to the controlled device according to the operational state of the controlled device and the motion of the remote controller; wherein, when the distance is not within the preset distance range, the first BLUETOOTH circuit is switched from a working state to a sleep state.
