A connector for electrical cables includes a tubular housing of electrically conductive material, an inner housing of electrically insulating material, and a plurality of electrical contacts positioned in the inner housing. The electrical contacts are configured to be connected to a conductor of an electrical cable and include two sides, each side having a discontinuous contact positioning feature. Optionally, the inner housing includes a substantially hollow center wall having a plurality of wall reinforcement ribs. A terminated cable assembly includes the connector for electrical cables and an electrical cable electrically connected to the connector.

A system for tuning an integrated optical switch element utilizes a reflection from a light signal that is propagated into a first input port defined on one side of an interaction region of the optical switch element. The reflection occurs beyond an opposite side of the interaction region from the side on which the light signal is introduced. The reflection is detected at a second input port of the optical switch element on the same side of the interaction region as the side on which the light signals is introduced. The reflection is used to tune the optical switch element to a desired switch state by minimizing the reflection detected at the second input port. By minimizing the reflection detected at the second input port for a desired switch state, the strength of the optical signal through the wave guide channels intended to be used to propagate the light signal in the desired switch state is maximized. As a result, the switching extinction ratio for the optical switch element in the desired switch state is optimized. The system can be used to selectively tune a single optical switch element, or can be used to selectively tune multiple integrated optical switch elements that form an optical switch matrix on a common substrate, for example.

The disclosure relates to a light source positioned behind a liquid crystal display, the output from the liquid crystal being projected onto a projection screen that has random polarization, thereby permitting a wide range of vision. The screen can be a part of the liquid crystal display by providing a frosted surface thereon which permits diffusion of the light emanating from the display.
