Abstract

A charging system can include a housing. The housing can include a controller. The housing also can include a power source configured to power the controller. The charging system also can include a wireless charger configured to transfer energy to the power source. The wireless charger can include a first indicator. The first indicator can be configured to provide a first non-flashing visual output at a first brightness level and indicative of a first charging status of the power source. The first indicator also can be configured to provide a second non-flashing visual output at a second brightness level indicative of a second charging status of the power source. Other embodiments are disclosed.

Claims (59)

1 . A charging system, comprising:

a housing, comprising:

a controller; and

a power source configured to power the controller; and

a wireless charger configured to transfer energy to the power source, comprising:

a first indicator configured to provide:

a first non-flashing visual output at a first brightness level and indicative of a first charging status of the power source; and

a second non-flashing visual output at a second brightness level indicative of a second charging status of the power source.

2 . The charging system of claim 1 , wherein:

the first indicator is configured to indicate a charging rate of the power source.

3 . The charging system of claim 1 , wherein:

the first indicator comprises a light emitting diode (LED).

4 . The charging system of claim 1 , wherein:

the first indicator is configured to prompt a user to adjust a position of the housing relative to the wireless charger to achieve a higher charging rate for the power source of the housing.

5 . The charging system of claim 1 , wherein:

the wireless charger is integrated into an object in an environment of a user of the housing.

6 . The charging system of claim 5 , wherein:

the object in the environment of the user is one or more of: a vehicle interface, a recreational accessory, or a wearable device.

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

one or more of audio output or haptic output indicative of the first charging status of the power source or the second charging status of the power source.

8 . The charging system of claim 1 , wherein:

the wireless charger uses inductive coupling to transfer energy from the wireless charger to the power source.

9 . The charging system of claim 1 , wherein:

the controller is configured to detect that a charging rate at which the power source is receiving energy from the wireless charger is above a threshold.

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

a second indicator disposed at the housing.

11 . A method for charging a housing, comprising:

providing the housing, comprising:

providing a controller; and

providing a power source configured to power the controller; and

providing a wireless charger configured to transfer energy to the power source, comprising:

providing a first indicator configured to provide:

a first non-flashing visual output at a first brightness level and indicative of a first charging status of the power source; and

a second non-flashing visual output at a second brightness level indicative of a second charging status of the power source.

12 . The method of claim 11 , wherein:

the first indicator is configured to indicate a charging rate of the power source.

13 . The method of claim 11 , wherein:

the first indicator comprises a light emitting diode (LED).

14 . The method of claim 11 , wherein:

the first indicator is configured to prompt a user to adjust a position of the housing relative to the wireless charger to achieve a higher charging rate for the power source of the housing.

15 . The method of claim 11 , wherein at least one of:

the wireless charger is integrated into an object in an environment of a user of the housing; or

the object in the environment of the user is one or more of: a vehicle interface, a recreational accessory, or a wearable device.

16 . The method of claim 11 , further comprising:

one or more of audio output or haptic output indicative of the first charging status of the power source or the second charging status of the power source.

17 . The method of claim 11 , further comprising:

transferring energy from the wireless charger to the power source using inductive coupling.

18 . The method of claim 11 , further comprising:

detecting, by the controller, that a charging rate at which the power source is receiving energy from the wireless charger is above a threshold.

19 . The method of claim 11 , further comprising:

disposing a second indicator at the housing.

20 . A charging system, comprising:

a housing, comprising:

a controller and at least one sensor; and

a power source configured to power the controller; and

a wireless charger configured to transfer energy to the power source, comprising:

a first indicator configured to provide:

a first non-flashing visual output at a first brightness level and indicative of a first charging status of the power source; and

a second non-flashing visual output at a second brightness level indicative of a second charging status of the power source.
