    Abstract: A sensor system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes a connection detection device, a power source, and a delay circuit. The connection detection device determines if the sensor electronics device is connected to the sensor and transmits a connection signal. The delay circuit receives the connection signal, waits a preset hydration time, and couples the regulated voltage from the power source to an electrode in the sensor after the preset hydration time has elapsed. Alternatively, the sensor electronics device may include an electrical detection circuit and a microcontroller. The electrical detection circuit determines if the plurality of electrodes are hydrated and generates an interrupt if the electrodes are hydrated. A microcontroller receives the interrupt and transmits a signal representative of a voltage to an electrode of the plurality of electrodes.

    Abstract: A monitor system to monitor a characteristic of a user is disclosed. A monitor system includes a sensor producing signals indicative of glucose characteristics within the user. The sensor has a connector with a plurality of contacts, at least two contacts being shorted by a fuse trace. The monitor system further includes an electronics package with a package housing. The package housing contains a battery, a package port interfaced with the connector to receive signals from the sensor, and a package processor to process the signals from the sensor. Further included in the monitor system is a fuse system controlled by the package processor that includes a fuse timer, wherein the fuse trace is destroyed after the fuse timer reaches a threshold value.

    Abstract: A sensor assembly for sensing a physiological characteristic of a user includes a power source, a power control switch, and a power latch within a housing. The power control switch is electrically coupled to the power source, and is configured to inhibit delivery of power from the power source to one or more components of the sensor assembly before deployment of the sensor assembly to a user, and deliver power from the power source to the one or more components of the sensor assembly in response to the deployment of the sensor assembly to the user. The power latch is configured to, upon the deployment of the sensor assembly to the user, latch an output of the power control switch to maintain the delivery of power from the power source to the one or more components of the sensor assembly while the sensor assembly is in a deployed state.
