ABSTRACT:
An electrical circuit for bi-directional power control between two devices, including a first battery-operated device, including a first battery for providing a source of power to the first battery-operated device, a first power management subsystem connected to the first battery, to power on and power off components of the first battery-operated device in response to a first wakeup event, WE1, and a first on/off button for generating WE1, a second battery-operated device, including a second battery for providing a source of power to the second battery-operated device, a second power management subsystem connected to the second battery, to power on and power off components of the second battery-operated device in response to a second wakeup event WE2, a second on/off button for generating WE2, and a switch for generating WE1simultaneously when the second on/off button generates WE2, and circuitry including a single connection inter-connecting the first power management subsystem, the first on/off button, the second power management subsystem, the second on/off button, and the switch for generating WE1.
