  • Patent number: 5939609
    Abstract: The multi-use sensor has a controllable number of measurement cycles. This multi-use sensor consists of a sensor and/or electrodes that are encased in a suitable material to allow reuse of the sensor and sensor life cycle circuitry that functions to regulate the number of operational cycles that the sensor can execute to ensure that the multi-use sensor is not used beyond its effective life. Included in this life cycle circuitry is a dual state mechanism that is connected across two conductors and that has a first state of low impedance. There is sensor state change apparatus that changes the state of the dual state mechanism to a second state of high impedance, such as an open circuit between the two conductors.
