Abstract
Circuits, methods, and apparatus that can transfer data and power between an optical-communication device and an electronic device without the need for electrical contacts on the electronic device. An example can include infrared transmitters and receivers in both the optical-communication device and the electronic device for optical communication. This can further include a coil in the optical-communication device that can be powered to inductively induce currents in a corresponding coil in the electronic device to charge a battery. One or more attachment components, such as magnets or magnetic elements, can be used to secure the optical-communication device to the electronic device. The optical-communication device to the electronic device can each include an alignment magnet or magnetic element. Either or both the optical-communication device and the electronic device can include digital signal processors in their receive paths to compensate for distortions and artifacts in the optical transmission and receive paths.
