Abstract: A connector system (C) for forming an electrical connection between two electronic or electrical assemblies includes a conductive tubular female member (40) and a compatible flexible male member (44). The male member (44) preferably comprises a helical coil spring-like wire portion (50) about a central axial post (52) for establishing electrical contact with and removably mating with an interior surface (42) of the conductive tubule receptacle member (40) electrically connected with an electronic assembly (28).

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 night vision device with improved user safety includes a head gear support structure which suspends a night vision viewer relative to the head and eyes of the user. The head gear includes a flip up mount allowing the user to flip the night vision viewer up and out of the user's line of sight for an unobstructed natural view of the environment. In order both to save battery power, and to prevent the user from inadvertently revealing his position by forgetting to turn off the night vision viewer before flipping it up, the support structure includes a magnetic flux source cooperable with a magnetically-responsive switch of the night vision viewer to maintain the viewer turned on only when the viewer is in its use position. When the viewer is flipped toward its upward position, the switch of the viewer is carried out of magnetic association with the flux source so that the viewer shuts off.

Abstract: A night vision scope which includes an improved voltage supply. A battery generates a voltage which is proportionally increased by a voltage step-up circuit to provide a voltage to an image intensifier and an infrared light source of the night vision scope. The voltage supply includes circuitry for limiting the voltage output of the voltage supply circuit if a battery is used which generates a voltage greater than that required by the elements of the night vision scope.
