Method and System for Powering an Electronic Device

摘要

Methods and apparatus for providing a power supply to a device, including an inductive rechargeable power supply for a data monitoring and management system in which a high frequency magnetic field is generated to provide power supply to a rechargeable power source such as a battery of a transmitter unit in the data monitoring and management system are provided.

主权项

1. A method, comprising:
generating a magnetic field at a receiver unit during a time period associated with data communication between sensor electronics and the receiver unit, wherein generating the magnetic field is programmed to 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 one or more signals are generated by the analyte sensor and associated with a monitored analyte level; inductively coupling 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 associated with the data communication; and communicating data associated with the monitored analyte level from the sensor electronics to the receiver unit during the time period.
