Patent ID: 8267598

Claim:
An optical communication system for conveying signals between a first and a second housing element of a device, where the first and second housing elements are adapted to move relative to one another, the communication system comprising: one or more optical light sources, each optical light source being coupled to one of the first and second housing elements; and one or more optical detectors, each optical detector corresponding to a respective one of the one or more optical light sources between which an optical communication connection via a respective one of one or more point to point communication paths is established, each of the one or more optical detectors being coupled to the other one of the first and second housing element, to which the respective corresponding optical light source is not coupled; and wherein as the housing elements move relative to one another, the corresponding one or more optical light sources move relative to the corresponding respective one of the one or more optical detectors, while maintaining the point to point communication connection between a common point of the corresponding one or more optical light sources and a common point of the respective one of the one or more optical detectors.
