Electronic devices and methods for non-contact hardware shutdown and/or reset of electronic devices

An electronic device comprising:

• a battery;
• a system load;
• a switch in an electrical connection path between the battery and the system load;
• a non-contact sensor configured to detect a wireless control signal associated with an instruction;
• a control circuit configured to, in response to the detected wireless control signal, open the switch to disconnect the battery and the system load, wherein the control circuit includes a timing circuit configured to control a time delay after detecting the wireless control signal and before opening the switch, and wherein the timing circuit includes a clock and a counter;
• and
• a charging interface configured to receive electric power from an external source, wherein the control circuit and the non-contact sensor are powered through the charging interface rather than the battery.

An electronic device comprising:

• a battery:
• a system load, wherein the system load includes a drive circuit of a motor of an infusion pump;
• a switch in an electrical connection path between the battery and the system load;
• a non-contact sensor configured to detect a wireless control signal associated with an instruction;
• a control circuit configured to, in response to the detected wireless control signal, open the switch to disconnect the battery and the system load;
• and
• a charging interface configured to receive electric power from an external source, wherein the control circuit and the non-contact sensor are powered through the charging interface rather than the battery.
