Abstract

A connector socket has a cylinder-shaped head with a substantially planar end face and a substantially cylindrical side wall. The end face has slots each for receiving an electrical connector pin and the side wall comprises a set of locking channels, each for receiving a locking lug. The locking channels each comprise an entry channel having a first end which opens at the end face and a second end opposite to the first end. Two side channels extend laterally in opposite directions from the second end of the entry channel. The locking channels thereby enable rotation of an attachment (e.g. external component or protective cap) during coupling in both directions. This reduces wear of the walls that define the locking channels.

Abstract

This invention relates to a target acquisition method and system for steerable light beams in optical wireless communication or fee-space optical communication systems, wherein a duration during which a steerable light beam of a transmitter must illuminate an optical detector at a receiver for acquisition can be minimized and a slow feedback channel from the receiver to the transmitter can be allowed. This can be achieved by emitting a pseudo-random sequence with a property that knowledge of a small number of bits uniquely allows determination of a beam direction at which the steerable beam of the transmitter is received by the receiver. In an example, a linear feedback shift register sequence is an appropriate and very efficient choice.
