    Abstract: In an example, a mobile computing device such as a tablet, laptop, or convertible is operable to couple to a docking station via high-frequency wireless such as WiGig at 60 GHz. Because high-frequency signals are highly directional, the mobile computing device is provided with a high-frequency antenna operable as a rotor. In one embodiment, the antenna is freely hinged to a gravitational pivot, and pivots toward the docking station responsive to gravitational torque. In another embodiment, an actuator drives the antenna to a correct angle responsive to a rotational sensor. In this case, an angle sweep may be performed around a midpoint to identify a best angle for high-frequency communication.

    Abstract: A method and apparatus for controlling the power supply for a system. In one embodiment, a power supply apparatus comprises a rechargeable battery; and a battery charger coupled to the battery and comprising a first circuit to generate an output that controls whether the battery is to provide power to the system to supplement the power provided by the power source when an input voltage from the power source of undetermined output power is less than a predetermined level.
