Abstract:
1. A method for reducing power consumption in a primary unit capable of transferring power to a secondary device, said secondary device separable from said primary unit, said method comprising the steps of: detecting presence of an object within proximity of said primary unit; sending a pulse of power to said object in response to detecting presence of said object within proximity of said primary unit; determining whether a valid secondary device is present in proximity to said primary unit in response to sending said pulse of power to said object; in response to a determination that a valid secondary device is not present, restricting power supplied to said primary unit; and further including in response to determining that a valid secondary device is present, determining whether said valid secondary device desires power, and in response to a determination that no present valid secondary devices desire power, restricting power supplied to said primary unit.
