Method and Apparatus for Providing Rechargeable Power in Data Monitoring and Management Systems
First Claim
1. An apparatus comprising:
- a transmitter including an analog front end, a processor, a first power supply configured to provide an operational voltage level to the analog front end, and a single large capacitor, wherein the first power supply is coupled to a boost circuit, and wherein the single large capacitor is coupled in parallel with the first power supply; and
a transmitter mount configured to receive the transmitter and including a second power supply configured to provide a supply voltage level to the first power supply of the transmitter to charge the first power supply of the transmitter when the transmitter is received by the transmitter mount;
wherein the boost circuit is configured to convert the supply voltage level received from the second power supply to the operational voltage level and wherein the single large capacitor is configured to store the operational voltage.

Abstract
Method and apparatus for providing a disposable power supply source integrated into the housing of the transmitter unit mount that is placed on the skin of the patient, and configured to receive the transmitter unit is disclosed. The transmitter unit mount is configured to be disposable with the analyte sensor so that power supply providing power to the transmitter unit is also replaced. The transmitter unit may include a rechargeable battery that is recharged by the power supply unit of the transmitter unit mount when the transmitter is mounted to the transmitter unit mount. Other energy store configurations including single large capacitor (supercap) or a capacitor and DC/DC converter configurations are disclosed.
