Abstract

A ring includes an inner surface configured to contact a finger of a user when the ring is worn by the user. The ring can include a first power source configured to be wirelessly charged by a second power source that is (i) removably coupled along a circumference of the inner surface of the ring, and (ii) disposed at an outer surface of the ring. The ring also can include a sensor configured to draw energy from the first power source and sense an activity of the user wearing the ring.

Claims (36)

1 . A ring comprising: an inner surface configured to contact a finger of a user when the ring is worn by the user; a first power source configured to be wirelessly charged by a second power source that is (i) removably coupled along a circumference of the inner surface of the ring, and (ii) disposed at an outer surface of the ring; and a sensor configured to draw energy from the first power source and sense an activity of the user wearing the ring; wherein: the ring is configured to send data to a communication device; and the communication device comprises one or more of: a wearable device, a mobile device, a secure access panel, a recreational accessory, or a vehicle interface, each of which are separate from the ring.

2 . The ring of claim 1 , wherein:

the activity of the user, as sensed, comprises one or more of: a biometric of the user, a physiological state of the user, or a signal indicative of an environment of the user.

3 . The ring of claim 1 , further comprising:

a second sensor configured to detect whether the second power source is coupled to the ring.

4 . The ring of claim 1 , wherein:

the first power source is configured to operate at different power modes.

5 . The ring of claim 1 , wherein:

the sensor senses the activity via one or more of a light, a sound, an acceleration, a chemical composition, a temperature, a translational movement, or a rotational movement.

6 . The ring of claim 1 , wherein:

the second power source is a rechargeable power source.

7 . The ring of claim 1 , wherein:

the second power source is a rechargeable power source on another device.

8 . The ring of claim 1 , wherein:

the outer surface of the ring is opposite to the inner surface of the ring.

9 . One or more non-transitory computer-readable media comprising computing instructions that, when executed on one or more processors, cause the one or more processors to perform operations comprising: wirelessly transferring energy to a first power source disposed within a ring from a second power source that is (i) removably coupled along a circumference of an inner surface of the ring, and (ii) disposed at an outer surface of the ring; and performing, by a sensor, sensing an activity of a user wearing the ring, wherein: the ring is configured to send data to a communication device; and the communication device comprises one or more of: a wearable device, a mobile device, a secure access panel, a recreational accessory, or a vehicle interface, each of which are separate from the ring.

10 . The one or more non-transitory computer-readable media of claim 9 , wherein:

the activity of the user, as sensed, comprises one or more of: a biometric of the user, a physiological state of the user, or a signal indicative of an environment of the user.

11 . The one or more non-transitory computer-readable media of claim 9 , wherein the operations further comprise:

using a second sensor to detect whether the second power source is coupled to the ring.

12 . The one or more non-transitory computer-readable media of claim 9 , wherein:

the first power source is configured to operate at different power modes.

13 . The one or more non-transitory computer-readable media of claim 9 , wherein:

the sensor senses the activity via one or more of a light, a sound, an acceleration, a chemical composition, a temperature, a translational movement, or a rotational movement.

14 . The one or more non-transitory computer-readable media of claim 9 , wherein:

the outer surface of the ring is opposite to the inner surface of the ring.

15 . A method of operating a ring, comprising: wirelessly transferring energy to a first power source disposed within the ring from a second power source that is (i) removably coupled along a circumference of an inner surface of the ring, and (ii) disposed at an outer surface of the ring; drawing the energy from the first power source by a sensor of the ring; and sensing an activity of a user wearing the ring, wherein: the ring is configured to send data to a communication device; and the communication device comprises one or more of: a wearable device, a mobile device, a secure access panel, a recreational accessory, or a vehicle interface, each of which are separate from the ring.

16 . The method of claim 15 , wherein:

the activity of the user, as sensed, comprises one or more of: a biometric of the user, a physiological state of the user, or a signal indicative of an environment of the user.

17 . The method of claim 15 , wherein:

transferring the energy to the first power source comprises transferring the energy to the first power source without removing the ring from a finger of the user.

18 . The method of claim 15 , wherein:

the outer surface of the ring is opposite to the inner surface of the ring.

19 . A ring comprising: a first power source configured to be charged by a second power source, wherein: the second power source is (i) removably coupled along a circumference of an inner surface of the ring, and (ii) disposed at an outer surface of the ring; and a sensor configured to draw energy from the first power source and sense an activity of a user wearing the ring, wherein: the outer surface of the ring is opposite to the inner surface of the ring, and wherein: the ring is configured to send data to a communication device; and the communication device comprises one or more of: a wearable device, a mobile device, a secure access panel, a recreational accessory, or a vehicle interface, each of which are separate from the ring.

20 . The ring of claim 19 , wherein:

the second power source is a rechargeable power source.
