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.

11. A glucose monitoring system, comprising:
-
a receiver unit comprising; a control unit configured to determine a time period for receiving one or more signals wirelessly transmitted from sensor electronics operatively coupled to an analyte sensor; and a power source section operatively coupled to the control unit, the power source section including a magnetic field generator unit configured to selectively generate a magnetic field for the determined time period in response to a command from the control unit; and a rechargeable power section, wherein the rechargeable power section is included with the sensor electronics and wherein the rechargeable power section is recharged when provided at a predetermined distance from the selectively generated magnetic field of the power source section during the determined time period; wherein the control unit provides the command to the power source section to control the magnetic field generator unit to alternatingly turn on or turn off the generation of the magnetic field only during the determined time period to selectively recharge the rechargeable power section. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
