Abstract: A system (S) for combining multi-spectral images of a scene includes a channel (18) for transmitting a scene image (10) in a first spectral band. A separate, second detector (22) senses the scene in a second spectral band. The second detector (22) has an image output that is representative of the scene. A display (28) displays an image (12) in the second spectral band. A beam mixer (30) combines the image output (10) in the first spectral band with the displayed image (12), and conveys the combined multi-spectral images to an output (32) for a user (U).

Abstract: A transportable power source (P) for an image viewing device (D) includes a battery pack housing assembly (10) to internally hold a first battery pack (12). An electrical interface circuit (14) receives an input voltage level (16) and provides a resulting output voltage level (18) as an output therefrom to operate the viewer device (D). The interface circuit (14) receives a selected first input voltage level (20) from the first battery pack (12). Alternatively, the interface circuit (14) receives a selected second input voltage level (22) from a power supply source (S) external to the battery pack housing (10). The interface circuit (14) further includes a switch (24) for selecting between sources of input voltage levels from among at least the first input voltage level (20) and the second input voltage level (22). The switch (24) also selectively controls the source for the resulting output voltage level (18).

Abstract: A fastening device (F) with first (16) and second sides (30) attaches a first device (10) to a mounting rail (12) of a second device (14). A top section (44) for mounting the first device extends from the first or second sides. The sides are adapted to removably clamp about the rail. A clamping member (46) extends between the first and second sides. An extended end (48) of the clamping member extends through the first side, and an opposing end (50) is coupled with the second side. The clamping member extended portion (48) is movably coupled to a single cam member (56) operably mounted with the first side for drawing the sides closer together into a clamping position (58) to mate the sides with the rail.
