Title:
BATTERY ADAPTER FOR NIGHT VISION DEVICE
Document Type and Number:
WIPO Patent Application WO2003067681
Kind Code:
A3
Abstract:
A battery adapter (A) replaces two batteries (10) with a single battery (10) housed within a compartment (48) of a battery powered electrical device (D). An electrically conductive housing (40) adapted to replicate a selected battery and fit within a space adapted to house two of the selected sized batteries. A step up circuit (18) mounted within the battery housing (40) receives an electrical signal from a single battery (10) and transforms the voltage of the electrical signal to simulate an electrical signal from two electrically connected selected batteries (10).
