1. A method, comprising:

  • determining a time period associated with transmitting one or more signals from an on-body device to a receiver unit, wherein the on-body device is operatively coupled to an analyte sensor and is configured to monitor an analyte level, the transmitted one or more signals from the on-body device to the receiver unit corresponding to one or more signals generated by the analyte sensor associated with the monitored analyte level;

    selectively generating a magnetic field at the receiver unit during the determined time period, wherein generating the magnetic field is programmed to automatically turn on or turn off only during the determined time period; and

    inductively charging a rechargeable power source of the on-body device when the on-body device is placed within a predetermined distance from the generated magnetic field during the determined time period.
