1. A method, comprising:

  • selectively generating a magnetic field at a receiver unit during a time period associated with a communication of one or more signals from sensor electronics to the receiver unit, wherein generating the magnetic field is programmed to automatically turn on or turn off only during the time period, and wherein the sensor electronics is operatively coupled to an analyte sensor in fluid contact with interstitial fluid, wherein the one or more signals are generated by the analyte sensor and associated with monitored analyte level; and

    inductively charging a rechargeable power source of the sensor electronics when the sensor electronics is placed within a predetermined distance from the generated magnetic field during the time period.
