Abstract

A charging system can include a housing. The housing can include an inner surface configured to contact a finger of a user when the housing is worn by the user. The housing also can include an internal power source configured to be wirelessly charged by a removable power source that is removably coupled to the housing. The housing further can include a component configured to draw energy from the internal power source. The charging system also can include a first LED activated in response to a first activity at the removable power source. The charging system further can include a second LED activated in response to a second activity at the removable power source. The second LED can be different from the first LED. The second activity can be different from the first activity. Other embodiments are disclosed.

Claims (59)

1 . A charging system comprising:

a ring housing comprising:

an inner surface configured to contact a finger of a user when the ring housing is worn by the user;

an internal power source configured to be wirelessly charged by a removable power source; and

a component configured to draw energy from the internal power source; and

a removable power source housing configured to be removably coupled to the ring housing and devoid of being worn on the finger of the user, the removable power source comprising:

a first LED activated in response to a first activity at the removable power source; and

a second LED activated in response to a second activity at the removable power source, wherein the second LED is different from the first LED, and the second activity is different from the first activity.

2 . The charging system of claim 1 , wherein:

one or more of the first LED or the second LED are disposed on the removable power source.

3 . The charging system of claim 1 , wherein:

the ring housing is configured for a friction fit with the removable power source housing.

4 . The charging system of claim 1 , wherein:

the removable power source is configured to charge the ring housing while the user is wearing the ring housing.

5 . The charging system of claim 1 , wherein:

the removable power source is an electrical charger configured to inductively transfer power to the internal power source.

6 . The charging system of claim 1 , wherein:

the ring housing is configured for a friction fit with the removable power source.

7 . The charging system of claim 1 , wherein:

the removable power source is integrated into an object in an environment of the user.

8 . The charging system of claim 1 , further comprising:

a controller configured to detect a presence of the ring housing at the removable power source.

9 . The charging system of claim 1 , wherein:

the ring housing is configured to operate in a power mode based on a presence of the removable power source adjacent to the ring housing.

10 . The charging system of claim 1 , wherein:

one or more of the first activity or the second activity comprises a presence of the removable power source adjacent to the ring housing.

11 . A method of providing a charging system, comprising:

providing a ring housing, comprising:

providing an inner surface configured to contact a finger of a user when the ring housing is worn by the user;

providing an internal power source configured to be wirelessly charged by a removable power source; and

providing a component configured to draw energy from the internal power source;

providing a removable power source housing configured to be removably coupled to the ring housing and devoid of being worn on the finger of the user, the removable power source housing comprising:

providing a first LED activated in response to a first activity at the removable power source; and

providing a second LED activated in response to a second activity at the removable power source, wherein the second LED is different from the first LED, and the second activity is different from the first activity.

12 . The method of claim 11 , further comprising:

disposing one or more of the first LED or the second LED on the removable power source.

13 . The method of claim 11 , wherein:

the ring housing is configured for a friction fit with the removable power source housing.

14 . The method of claim 11 , wherein:

the removable power source is configured to charge the ring housing while the user is wearing the ring housing.

15 . The method of claim 11 , wherein:

the removable power source is an electrical charger configured to inductively transfer power to the internal power source.

16 . The method of claim 11 , wherein:

the ring housing is configured for a friction fit with the removable power source.

17 . The method of claim 11 , wherein:

the removable power source is integrated into an object in an environment of the user.

18 . The method of claim 11 , further comprising at least one of:

providing a controller configured to detect a presence of the ring housing at the removable power source; or

one or more of the first activity or the second activity comprises a presence of the removable power source adjacent to the ring housing.

19 . The method of claim 11 , further comprising:

operating the ring housing in a power mode based on a presence of the removable power source adjacent to the ring housing.

20 . A charging system comprising:

a ring housing comprising:

an inner surface configured to contact a finger of a user;

an internal power source configured to be wirelessly charged by a removable power source; and

a light source configured to draw energy from the internal power source;

a removable power source housing configured to be removably coupled to the ring housing and devoid of being worn on the finger of the user, the removable power source housing comprising:

a first LED activated in response to a first activity at the removable power source; and

a second LED activated in response to a second activity at the removable power source, wherein the second LED is different from the first LED, and the second activity is different from the first activity.
