Abstract
A wireless electronic device includes a rechargeable battery, a receiver, and a shut down module. The rechargeable battery is at least partially charged. The receiver is configured to enable wireless communications for the wireless device. The receiver is capable of receiving wireless commands configured to cause corresponding functions to be performed in the wireless electronic device, which may include test functions, calibration functions, and shut down functions. The shut down module is configured to cause the wireless electronic device to initiate a shut down protocol according to a shut down command received by the receiver.
Claims20
A method, comprising:
- at least partially charging a rechargeable battery of a manufactured wireless electronic device, wherein the wireless electronic device does not include a wired communication interface;
- and
- transmitting at least one wireless command to the wireless electronic device that is configured to cause a function to be performed in the wireless electronic device, said transmitting at least one command including transmitting a shut down command to the wireless device to perform a shut down function in the wireless electronic device, the shut down command causing the rechargeable battery to transition to a low power mode configured to reduce self-discharge;
- the wireless electronic device leaving a manufacturing facility in which the wireless electronic device was manufactured subsequent to said transmitting the shut down command to the wireless device.
A method in a wireless electronic device, comprising:
- receiving a current that at least partially charges a rechargeable battery of the wireless electronic device;
- receiving at least one wireless command at the wireless electronic device configured to cause a function to be performed in the wireless electronic device, wherein the wireless electronic device does not include a wired communication interface, said receiving at least one wireless command including receiving a shut down command at the wireless electronic device to perform a shut down function in the wireless electronic device, the shut down command causing the rechargeable battery to transition to a low power mode configured to reduce self-discharge;
- and
- performing the function prior to the wireless electronic device leaving a manufacturing facility in which the wireless electronic device was manufactured.
A wireless electronic device, comprising:
- a rechargeable battery that is at least partially charged;
- a receiver configured to enable wireless communications for the wireless device, the receiver being capable of receiving wireless commands configured to cause corresponding functions to be performed in the wireless electronic device, the wireless electronic device not including a wired communication interface;
- and
- a shut down module configured to cause the wireless electronic device to initiate a shut down protocol according to a shut down command received by the receiver, the shut down module configured to cause the rechargeable battery to transition to a low power mode that is configured to reduce self-discharge of the rechargeable battery in response to the shut down command.
