Abstract: A method and apparatus for monitoring MEMS-based optical switches and cross-connects. A plurality of partial reflectors (24) are introduced into optical paths of the switch (10) for reflecting light transmitted along the optical paths through a transparent substrate of the switch (10), without disturbing transmission of the light along the optical paths. The reflected light is transmitted through the substrate (20), which is preferably made of silicon and transparent to wavelengths of light used in DWDM systems. A photodetector array bonded to the underside of the substrate detects the light reflected by the plurality of partial reflectors (24) through the substrate (20). The light detected by the photodetector array (30) indicates the switching states and functionality of the switch (10), and can be processed by circuitry associated with the array.

Abstract: A tactical rail for a firearm includes a rail body having a receiver end and a muzzle end, a non-contact optical connection, and a high speed data spoke. The non-contact optical connection is arranged at an end of the rail body and is configured to interface with a corresponding non-contact optical interface. The high speed data spoke is connected to the non-contact optical connection for high speed data communication through the non-contact optical connection and the corresponding non-contact optical interface. Tactical rail arrangements and firearm with tactical rails and tactical rail arrangements are also described.

Abstract: A tactical rail for a firearm includes a rail body having a receiver end and a muzzle end and a non-contact optical connection arranged at an end of the rail body and configured to interface with a corresponding non-contact optical interface. A low speed data bus segment extends between the receiver end and the muzzle end of the rail body. A high speed data spoke is connected to the non-contact optical connection for high speed data communication with a high speed data accessory through the non-contact optical connection and the corresponding noncontact optical interface. Tactical rail systems and firearm assemblies having tactical rails are also described.

Abstract: An eyecup (100) for an optic includes an elastic body (101) forming an eye receiver (103) and a viewing cavity (105), the elastic body configured to move between a relaxed state (fig 1) and a compressed state (fig 3); and a diaphragm (107) formed from or attached to an inner surface (109) of the elastic body, the diaphragm including one or more flaps (111) configured to be in a closed position when the elastic body is in the relaxed state such that the one or more flaps block sight of an optic through the viewing cavity, and to be in an open position when the elastic body is in the compressed state such that the one or more flaps allow sight of an optic through the viewing cavity and one or more magnets (113) are sensed by one or more sensors (115) to activate an optic display (501).

Abstract: A method and an apparatus for enhancing images are provided. An input image generated by an imaging device, such as a short- wavelength infrared (SWIR) camera, sensor, or any other imaging device, is processed to produce an input histogram representing the distribution of pixel intensities in the input image. Histogram start and end points are determined, and a variable plateau profile is calculated depending upon the type of enhancement desired. The plateau profile could take on any desired shape or size, and two or more plateau regions could be included in the profile. The input histogram is clipped along the variable plateau profile. A cumulative histogram is constructed from the clipped histogram, and is normalized. The input image is then transformed into an enhanced output image using the normalized cumulative histogram as a look-up table.
