Abstract: Various embodiments of the present invention provide optical multi-channel free space interconnects that provide optical channel isolation, thereby reducing crosstalk.

Abstract: A micro-electrical mechanical system (MEMS) mirror assembly including an array of micro-mirrors formed on a substrate and having springs on one side and which angularly tilt between ON and OFF states in response to an electrostatic force generated by a voltage applied to an electrode located on the substrate. At least one, but preferably two springs in the form of two thin strips of metal attach to post(s) at the side edge of the mirror and act as springs which provide a restoring force when the mirror is tilted between an OFF state which occurs when the mirror is flat relative to the substrate with no voltage applied, and in the ON state when the mirror is tilted when a voltage is applied.

Abstract: A container security system has a container interior monitor portion with a container interior light sensing portion responsive to visible light. A different embodiment involves a monitoring device with a support, a door engaging member movable to and from an operational position, and a detection portion that generates an electrical signal in response to movement of the member away from the operational position. The support may be configured to be supported on an edge portion of a movable door. Alternatively, the monitoring device may include a wireless communication portion, and circuitry responsive to the signal and operatively coupled to the wireless communication portion.

Abstract: A device has a support that can resiliently and removably grip an edge portion of a member with first and second portions thereof disposed on opposite sides of the member. A further portion on the first portion can operatively couple sensing structure to an electrical conductor portion on the third portion. A different embodiment has a support that can resiliently and removably grip an edge portion of a member with first and second portions thereof disposed on opposite sides of the member. A further portion on the support has circuitry coupled to a wireless communication portion on the first portion. Another embodiment has a support with structure supported thereon, the support resiliently and removably gripping the edge portion of a movable door with first and second portions of the support disposed on opposite sides of the edge portion.
