20140253026 | Apparatus, Method, and System for Wirelessly Charging an Electronic Device - An apparatus for wirelessly charging an electronic device is disclosed. The apparatus comprises a charging controller coupled to a power source, a power switch coupled to the power source, a logic controller coupled to the power switch, and a wireless charger transmitter coupled to the power source via the power switch and coupled to the logic controller. The charging controller is configured to transmit power from the power source to a load in the apparatus. The logic controller is configured to detect if the electronic device is wirelessly coupled to the apparatus and to switch on the power switch when the electronic device is detected to be wirelessly coupled. The wireless charger transmitter is integrated in the apparatus and configured to wirelessly transmit power from the power source to the electronic device when the power switch is on. | 09-11-2014 |
20140152187 | CIRCUITS AND METHODS FOR DRIVING A LIGHT SOURCE - A circuit includes a bridge circuit, a converter, and a controller. The bridge circuit receives power from first and second power lines of a switch and generates a rectified voltage. The switch is capable of operating in a first state in which the switch conducts power to the first power line but not the second power line, a second state in which the switch conducts power to the second power line but not the first power line, and a third state in which the switch conducts power to both the first and second power lines. The converter converts the rectified voltage to an output voltage to drive a light source, and controls a current through the light source according to a driving signal. The controller monitors the operation state of the switch and generates the driving signal based on the operation state to control brightness/dimming of the light source. | 06-05-2014 |

20130246270 | Method and System for Multi-Modal Identity Recognition - A device, a system and a method are provided for multi-modal identity recognition. The device includes a face recognition unit, a voice recognition unit, and a control unit. The face recognition unit is configured for generating a first recognition result by obtaining and processing face recognition information of a customer and by comparing the processed face recognition information with face recognition information stored in a facial feature database. The voice recognition unit is configured for generating a second recognition result by obtaining and processing voice recognition information of a customer and by comparing the processed voice recognition information with voice recognition information stored in an audio signature database. The control unit is configured for confirming an identity of the customer based on the first recognition result and the second recognition result. | 09-19-2013 |
20130245970 | Apparatus and Method for Detecting Battery Abnormality and Cause Thereof - Methods and apparatus for detecting abnormality of a battery pack are disclosed. The battery pack includes multiple battery cells coupled in series via at least one connecting wire. A first voltage drop between a positive electrode and a negative electrode of the battery pack is detected. A first set of voltage drops between a positive electrode and a negative electrode of each battery cell in the battery pack is also detected. A total voltage drop across the at least one connecting wire in the battery pack is calculated based on an absolute difference between the first voltage drop and a sum of the first set of voltage drops. Whether the battery pack is abnormal is determined by assessing the total voltage drop across the at least one connecting wire with respect to a predetermined threshold. | 09-19-2013 |
20130243332 | Method and System for Estimating an Object of Interest - Method and system for estimating an object of interest are provided. Visual information of a customer's face is obtained. Pupil location information indicative of at least a location of a pupil of an eye of the customer is determined based on the visual information. A field of view of the customer is determined based on the visual information. Then a focal point of the customer is determined based on the pupil location information, the field of view, and a predetermined focus condition. An object of interest of the customer is estimated based on the focal point. Information associated with the object is provided to the customer. | 09-19-2013 |
20120112703 | System and Method for Managing a Battery - A method for managing a battery with multiple battery cells is disclosed. The method includes monitoring parameters of the battery cells by an information acquisition unit. Parameters of the battery cells include individual cell voltages. The method further includes selecting, by a controller one of multiple charging modes in which the battery cells are charged according to the cell voltages. The charging modes include a constant current charging mode, a constant voltage charging mode, and a pulse charging mode. | 05-10-2012 |
