Abstract: A first electronic device is positionable between one or more contact positions and an aligned position with respect to a second electronic device. One or more actuators of the first electronic device are activated in response to one or more sensors of the first electronic device determining that the first electronic device and second electronic device are misaligned. Activation of the actuator may result in the first electronic device moving to the aligned position. In some implementations, the actuator may move the first electronic device toward the aligned position when activated. In other implementations, the actuator may overcome static friction to put the first electronic device in motion when activated and when the first electronic device is in motion one or more alignment mechanisms may overcome the kinetic friction to move the first electronic device to the aligned position.

Abstract: An example method is performed at a first transmitter in communication with other power transmitters, the method including: receiving, from a respective transmitter of the other transmitters, information indicating at least (1) a network address, and (2) status information regarding whether the respective transmitter is in master or non-master mode. The method also includes, if none of the other power transmitters is in the master mode, determining whether a first network address of the first transmitter is lower than respective network addresses of the other transmitters. The method further includes: if the first network address is lower than the respective network addresses: operating the first transmitter in the master mode; and sending an indication that the first transmitter is in the master mode. While the first transmitter is in the master mode, the first transmitter assigns each of the other transmitters to transmit power waves to one or more receivers.

The light fixture may be caused to operate in the emergency lighting mode when a main electrical power supply is interrupted or when performances of the light fixture and of the onboard battery are tested.
