Zusammenfassung:A sensor assembly for sensing a physiological characteristic includes a power source, a power control switch, and a power latch configured to latch an output of the power control switch. The sensor assembly also includes a power converter coupled to the power control switch. The power converter is configured to step down a voltage of the latched output of the power control switch for delivery of the latched output to one or more components of the sensor assembly. The power control switch is configured to inhibit consumption of power from the power source when the sensor assembly is in a pre-deployment state and output the latched output to the power converter in response to transition of the sensor assembly from the pre-deployment state to a deployed state.
