Abstract: A powered joint having a first joint component and second joint component in which the first joint component has multiple degrees of rotational freedom with respect to the second joint component, the powered joint including one or more power transmission coils associated with the first component; a plurality of power receiving coils associated with the second component; a sensor which determines the orientation of the second component with respect to the first component; and a control circuit for selectively connecting one of the plurality of power receiving coils to a power receiving circuit based on information received from the sensor.

Abstract: In an inductively coupled power transmitter a force detector that detects the presence of a potential device by monitoring forces applied to a surface of the power transmitter and activates the inductively coupled power transmitter upon detection of a potential device. An inductively coupled power transmitter having a proximity detector that detects the presence and location of a potential device by monitoring the proximity of devices to a surface of the power transmitter and activates the inductively coupled power transmitter upon detection of a potential device. The transmitter preferably has one or more detection coils each having an area much greater than that of the transmitter coils for detecting the presence of a potential device. An inductively coupled power transmitter including a plurality of transmitter coils proximate a charging surface and a controller selecting and driving a combination of transmitter coils providing the coupling between the power transmitter and a power receiver meeting a selection criteria.
