US Patent:

6448742, Sep 10, 2002

Filed:

Feb 15, 2001

Appl. No.:

09/784298

Inventors:

Michael D. Waterman - Chandler AZ

International Classification:

H01M 1046

US Classification:

320114

Abstract:

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

US Classification:

2502140VT

Abstract:

An adaptive electrical circuit unit (C) is used in a night viewer system (V) having an image intensifier tube () and a compatible power source (). A voltage gain detection circuit unit () is operably connected to the image intensifier tube () and detects multiple selected types of image intensifier tubes (). The voltage gain detection circuit () produces an output gain signal () that is appropriate to the detected image intensifier tube () for controlling the gain of the detected image intensifier tube ().
