First Claim
Patent Images
1. An indicator, for use with a battery sensor, that provides an indication when a parameter monitored by said battery sensor has achieved at least a threshold state, said indicator comprising:
- (a) input means for detecting the presence or absence of a signal from said battery sensor, wherein said input means provides an appropriate trigger signal when said parameter monitored by said battery sensor achieves at least said threshold state;
(b) first oscillator means responsive to said trigger signal for providing an output from said oscillator having a first frequency;
(c) second oscillator means responsive to said first oscillator output signal for providing a second oscillator output signal having a second frequency with said second frequency being different from said first frequency; and
(d) output means responsive to said second oscillator output signal for providing an indication of when said parameter has achieved at least said threshold state.

Abstract
A battery monitors by which an individual cell in a wet cell battery may be monitored for variations in the level of electrolyte contained in the cell. More specifically, the invention relates to a universal electrolyte level indicator which may be attached to, and made part of, battery powered mobile equipment of all types for the purposes of providing a warning indication to the operator of the equipment that water needs to be added to the batteries contained therein.
