Accelerometer-based battery charge status indicator
First Claim
1. A method for recharging a battery of an electronic device which has been placed in a cradle of a charging dock, comprising:
- measuring, by an electronic circuit, a charging voltage value and a charging current value for the electronic device;
detecting, by a position sensor of the electronic device or the charging dock, a first angular orientation for a current position of the electronic device when the electronic device has been disposed in the cradle of the charging dock;
determining, by the electronic circuit, whether the angular orientation is in a proper cradle range by comparing a first value of the angular orientation to a pre-defined second value of at least one reference angular orientation of the electronic device;
in response to a determination that the angular orientation is in the proper cradle range;
selecting, by the electronic circuit, at least one first indicator from a plurality of indicators to be output from the electronic device when both the charging voltage value and the charging current value equal zero, where the first indicator indicates that the charging dock may not be electrically coupled to a power source;
selecting, by the electronic circuit, at least one second indicator from the plurality of indicators to be output from the electronic device or charging dock when both the charging voltage value and the charging current value do not equal zero, where the second indicator indicates that the charging dock may be of a wrong type for charging the electronic device;
in response to a determination that the angular orientation is not in the proper cradle range, selecting, by the electronic circuit, at least one third indicator from the plurality of indicators to be output from the electronic device or charging dock; and
outputting, by the electronic circuit, the first, second or third indicator to the user of the electronic device.

Abstract
Systems (100) and methods (600) for recharging a battery (292) of an electronic device (102) which has been placed in a cradle (106) of a charging dock (104). The methods involve: measuring a charging voltage value and a charging current value for the electronic device; determining a first value of angular orientation for a current position of the electronic device relative to a reference angular orientation of the electronic device; selecting at least one first indicator from a plurality of indicators based on the charging voltage value, the charging current value, and the first value of angular orientation; and outputting a first indicator to the user of the electronic device.

8. A system, comprising:
-
an electronic device having a rechargeable battery; a charging dock comprising a cradle configured to receive the electronic device; and an electronic circuit configured to measure a charging voltage value and a charging current value for the electronic device, receive a first angular orientation for a current position of the electronic device which was detected by a position sensor of the electronic device or the charging dock when the electronic device was disposed in the cradle of the charging dock, determine whether the angular orientation is in a proper cradle range by comparing a first value of the angular orientation to a pre-defined second value of at least one reference angular orientation of the electronic device, in response to a determination that the angular orientation is in the proper cradle range; select at least one first indicator from a plurality of indicators to be output from the electronic device when both the charging voltage value and the charging current value equal zero, where the first indicator indicates that the charging dock may not be electrically coupled to a power source, select at least one second indicator from the plurality of indicators to be output from the electronic device or charging dock when both the charging voltage value and the charging current value do not equal zero, where the second indicator indicates that the charging dock may be of a wrong type for charging the electronic device; in response to a determination that the angular orientation is not in the proper cradle range, selecting at least one third indicator from the plurality of indicators to be output from the electronic device or charging dock; and output the first, second or third indicator to the user of the electronic device. - View Dependent Claims (9, 10, 11, 12, 13, 14)
