20100185877 | System and Method for Information Handling System Power Management by Variable Direct Current Input - A power manager of an information handling system selectively commands a first or second source voltage from an AC-to-DC adapter based upon power consumption of the information handling system. A lower direct current voltage is provided during reduced power consumption so that DC-to-DC conversion in a power supply is more efficient. A higher direct current voltage is provided during increased power consumption so that the current required to provide the increased power remains below a threshold current, thus allowing the power system to have components that operate at lower current levels under high power consumption operations yet with increased efficiency during low power consumption operations. | 07-22-2010 |

20140119596 | METHOD FOR RECOGNIZING GESTURE AND ELECTRONIC DEVICE - A method for recognizing a gesture adopted by an electronic device to recognize a gesture of at least a hand. In the method, a hand image of the hand is captured and the hand image includes a hand region. A geometric center of the hand region is calculated. At least a concentric circle is disposed on the hand region with the geometric center as the center of the concentric circles. A number of intersection points of each concentric circle and the hand region is calculated respectively to determine a feature vector of the gesture. According to the feature vector, a hand recognition is performed to recognize the gesture of the hand. | 05-01-2014 |
20150150054 | APPARATUS AND METHOD FOR GENERATING ELECTRONIC PROGRAM GUIDE - An apparatus and a method for generating electronic program guide (EPG) are provided. The EPG generating apparatus comprises a receiving interface and a processor. The receiving interface receives an inputting keyword group. The processor generates a program name keyword group according to the program name corresponding to a program description. The processor constructs a semantic similarity degree matrix according to the inputting keyword group and the program name keyword group, and constructs an undirected graph according to the semantic similarity degree matrix. The processor finds a maximum clique set of the undirected graph, and generates a match score according to the program description and the maximum clique set. The processor determines a recommendation sequence of the program name in the EPG according to the match score. | 05-28-2015 |

20160056600 | Information Handling System Multi-Axis Power Adapter - An information handling system power adapter removably couples with a multi-axis plug that rotates between storage, wall socket and power strip positions. The storage position rotates prongs that insert into a power socket so the prongs are retracted into the power adapter, rotates prongs to plug into a wall socket so that the power adapter aligns parallel to the wall having the wall socket, and rotates the prongs to plug into a power strip socket so that the power adapter aligns perpendicular to the power strip having the socket. The multi-axis plug inserts into a power cable receptacle of the power adapter so that an end user may selectively remove the multi-axis plug and insert a power cable that terminates at a plug to connect the power adapter with a power socket through the power cable. | 02-25-2016 |
20160097820 | Battery Performance Under high Temperature Exposure - A battery system for a portable information handling system may modify charging parameters based on temperature exposure of a battery. When the battery is charged and exposed to a high temperature, the battery may be discharged to a lower voltage. After a cumulative period of exposure to a high temperature, a top-of-charge (TOC) voltage may be permanently reduced for the battery. Prior to charging at a high temperature, the TOC voltage may be reduced for a next charge cycle. Reducing the TOC voltage may minimize adverse effects for battery performance. | 04-07-2016 |
