As noted above, in powering off the wireless transceiver and/or the wireless transmitter, the controller can configure and/or instruct the first energy storage device and/or the second energy storage device to halt transferring electrical energy to the wireless transceiver and/or the wireless transmitter.
Electrical energy can then be transferred from the first energy storage device, included in the device, to the input device 620. As noted above, in one embodiment, the input device can transfer the electrical energy to a second energy storage device included in the input device 630. Additionally, as noted above, the first energy storage device and the second energy storage device are devices which can be configured to receive, store, and/or transfer electrical energy in one or more batteries and/or one or more capacitors. In one embodiment, one or more batteries and/or one or more capacitors are comprised of cells.
Further, the controller can halt transferring the electrical energy to the second energy storage device when the second energy storage device is identified to be full 640. As noted above, the second energy storage device is identified to be full when the batteries and/or capacitors of the second energy storage device are filled with electrical energy. Additionally, the controller of the device, the device, the input device, and/or the second energy storage device can determine when the batteries and/or capacitors of the second energy storage device are filled with electrical energy.
In one embodiment, the controller can additionally configure and/or instruct one or more status indicators on the input device to output a signal when the second energy storage device is fully charged 650. One or more status indicators can include a second status indicator on the input device configured to output a visual and/or audible message. In one embodiment, the method is then complete. In other embodiments, the method of FIG. 8 includes additional steps in addition to and/or in lieu of those depicted in FIG. 8.
By transferring electrical energy from a first energy storage device to an input device when a device is operatively coupled to the input device, the input device can utilize the electrical energy to power the input device when transmitting one or more input commands for a machine to process. Additionally, by transferring electrical energy from the first energy storage device to charge a secondary energy storage device included in the input device, the input device can be powered by the second energy storage device to transmit one or more input commands to the machine when the device is not operatively coupled to the input device.
