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).
Claims21
A battery adapter device for replacing two known batteries with a single battery in a battery powered electrical device comprising:
- a single battery housing adapted to secure a single selected size battery and fit within a space adapted to house two of the selected sized batteries electrically connected to the electrical device;
- and,
- a step up circuit mounted within the battery housing for receiving an electrical signal from the single selected battery mounted within the housing and transforming an output voltage of the electrical signal for an output signal to simulate an electrical signal from two electrically connected selected batteries.
A viewing device comprising:
- a battery powered night vision device of the type including image intensification or thermal imaging;
- a battery adapter device for replacing two known batteries with a single battery in a battery powered electrical device;
- the battery adapter comprising:
- a single battery housing adapted to secure a single selected sized battery and fit within a space adapted to house two of the selected sized batteries electrically connected to the electrical device;
- and,
- a step up circuit mounted within the battery housing for receiving an electrical signal from the single selected battery mounted within the housing and transforming an output voltage of the electrical signal for an output signal to simulate an electrical signal from two electrically connected selected batteries.
A replaceable voltage supply assembly for a viewing device of the type including image intensification or thermal imaging comprising:
- a changeable single battery unit means for generating a first voltage;
- a battery adapter device for replacing two known batteries with a single battery in a battery powered electrical device;
- the battery adapter comprising:
- a single battery housing adapted to secure a single selected sized battery and fit within a space adapted to house two of the selected sized batteries electrically connected to the electrical device;
- and,
- a step up circuit mounted within the battery housing for receiving an electrical signal from the single selected battery mounted within the housing and transforming an output voltage of the electrical signal for an output signal to simulate an electrical signal from two electrically connected selected batteries.
