Wireless headset and battery status indication method thereof
First Claim
1. A battery status indication method for a wireless headset, the method comprising:
- determining a residual charge of a battery of the wireless headset; and
emitting light having one of a plurality of colors from a status indication unit of the wireless headset,wherein each of the plurality of colors indicates a different residual charge of the battery,wherein the light comprises a color corresponding to a current residual charge of the battery,wherein the emitting of the light comprises one of maintaining emission of the light and blinking of the light when the battery is coupled to an external power source, andwherein the emitting of the light comprises the other of maintaining the emission of the light and blinking of the light when the battery is not coupled to the external power source.

Abstract
An enhanced wireless headset and battery status indication method is provided for indicating an accurate battery level of a wireless headset. A battery status indication method for a wireless headset determines a residual charge of a battery of the wireless headset and emits light having one of a plurality of colors from a status indication unit of the wireless headset. Each of the plurality of colors indicates a different residual charge of the battery. The wireless headset and battery status indication method also enables indicating whether the wireless headset is operating in charging mode by maintaining or blinking the battery status indication light. In addition, the wireless headset and battery status indication method enables indicating a radio communication status as well as a battery status by blinking the battery status indication light in correspondence with a communication radio scanning cycle.
