Abstract

A system wearable on a body part of a user. The system includes an electronic device powered by a primary power source, and a circuitry coupled to the electronic device. The system also includes a removable secondary power source configured to charge the primary power source with secondary power when coupled to the circuitry.

Claims

1. A system for measuring health information of a user via a body part of the user, the electrical device being wearable on the body part of the user, the system comprising:

an electronic device powered by an internal primary power source embedded in the electronic device, and configured to measure the health information of the user via the body part;

a circuitry coupled to the internal primary power source having a predefined threshold, and configured to determine an amount of time elapsed in charging the internal primary power source, and to transmit data; and

a removable secondary power source configured to charge the internal primary power source with secondary power when the removable secondary power source is coupled to the internal primary power source through the circuitry and in response to the internal primary power source having reached the predefined threshold, and

wherein the circuitry is further configured to log the amount of time elapsed before a power level of the removable secondary power source drops below the predefined threshold, and to transmit data indicative of the logged amount of time.

2. A system of claim 1, wherein the predefined threshold comprises a time threshold.

3. A system of claim 1, wherein the predefined threshold comprises a power threshold.

9. A system of claim 8, wherein the at least one battery is contoured to the shape of the housing.

10. A system of claim 1, wherein the body part comprises a wrist.

11. A removable power system for providing secondary power to charge an electronic device for measuring health information of a user via a body part of the user, the electrical device being wearable on the body part of the user, the electronic device having an interface and a base module being powered by an internal power source embedded in the electronic device and having a predefined threshold, the removable power system comprising:

a circuitry coupled to the internal power source of the electronic device that measures the health information of the user via the body part, and configured to determine an amount of time elapsed in charging the internal primary power source, and to transmit data;

a fastener integrated with the interface; and

a removable power storage configured to charge the internal power source with secondary power from the removable power storage when the removable power storage is coupled to the internal power source through the circuitry and in response to the removable internal power source having reached the predefined threshold and to the removable power storage having been fastened to the fastener, and

wherein the circuitry is further configured to log the amount of time elapsed before a power level of the removable secondary power source drops below the predefined threshold, and to transmit data indicative of the logged amount of time.

12. A system of claim 11, wherein the predefined threshold comprises a time threshold.

13. A system of claim 11, wherein the predefined threshold comprises a power threshold.

14. A system of claim 11, wherein the circuitry includes a plurality of contacts configured to electrically couple the removable power storage to the internal power source.
