Abstract
Abstract A device for monitoring a particular function such as temperature for determining when the function is above a threshold level. A sensor responsive to the particular function being monitored provides a variable electrical signal in response to variations of the particular function. An electrical circuit is coupled to receive the variable electrical signal at an input. The electrical circuit is in a first state in response to the variable electrical signal above the threshold level and is in a second state in response to the variable electrical signal below the threshold level. A first electrolytic cell is coupled to the input of the electrical circuit and is responsive to the variable electrical signal when the electrical circuit is in the first state. A second electrolytic cell is coupled to the output of the electrical circuit and is responsive to a constant signal when the electrical circuit is in the first state.
