20080220854 | METHOD AND APPARATUS FOR COLLECTING USER GAME PLAY DATA AND CREDITING USERS IN AN ONLINE GAMING ENVIRONMENT - A computer implemented method for monitoring game play behavior of a user in an online gaming environment. Responsive to detecting execution of a game, gaming characteristics of the user are monitored. The game interacts with a game server. Game play data of the user is collected. Collecting game play data is performed by a plug-in application located on the game server. | 09-11-2008 |
20080220869 | METHOD AND APPARATUS FOR PROVIDING GAME GUIDE DATA IN A GAMING ENVIRONMENT - A computer implemented method, a data processing system, and a computer program product for presenting a user guide for supplementing game play. An exemplary method includes querying a source of data containing game guide data corresponding to a game. The game is executing on a data processing system. The source of data is external to the game. The method also includes presenting, while the game is executing in a foreground, the game guide data to the user in a dynamic window. | 09-11-2008 |
20080220872 | METHOD AND APPARATUS FOR ISSUING A CHALLENGE PROMPT IN A GAMING ENVIRONMENT - A computer implemented method, a data processing system, and a computer program product for providing game play security measures. An exemplary method includes retrieving a prompt rule set. The prompt rule set identifies at least one rule for providing challenges during game play. Responsive to detecting game play, a current game play condition is matched with the at least one rule of the prompt rule set. Responsive to matching the current game play condition with the at least one rule of the prompt rule set, a challenge prompt is presented to a user. The challenge prompt is presented in a dynamic window that is present while the user is playing the game. Responsive to receiving an answer to the challenge prompt, the answer is processed. | 09-11-2008 |

20090257256 | HIGH EFFICIENT INPUT CURRENT SHAPING FOR AC TO DC CONVERTERS WITH POWER FACTOR CORRECTION REQUIREMENT - A high efficient input current shaping AC to DC converter with PFC front end that reduces input current harmonics is provided. In one embodiment, an AC to DC converter connectable with an alternating current source and operable to output a direct current comprises a PFC front end followed by a DC/DC converter. The PFC front end reduces harmonic components present in an input current waveform received by the PFC front end from the alternating current source and includes current steering circuitry and, optionally, valley filling circuitry. The DC/DC converter comprises one that presents pure resistive input impedance to the PFC front end. The DC/DC converter outputs the direct current to a load connected thereto. | 10-15-2009 |
20090262562 | EFFICIENCY IMPROVEMENT IN POWER FACTOR CORRECTION - An power converter that is operable to convert AC power into DC power that may be delivered to a load. The power converter includes a transformer and a controllable switch. The switching frequency of the power converter is configured to be dependent on the level of the AC voltage of an AC power source. The switching frequency may be proportional to the AC voltage to provide a constant magnetic flux density swing for the transformer in the power converter. The switching frequency may be controlled by using a circuit that converts the AC voltage from the AC power source into a frequency signal that is proportional to the AC voltage. | 10-22-2009 |
20100182806 | Controller for a Power Converter - A controller for a power converter having a transformer T | 07-22-2010 |
20100188876 | Controller for a Power Converter - A controller for a power converter and method of operating the same employable with a bridge rectifier having first and second synchronous rectifier switches. In one embodiment, the controller includes an amplifier configured to enable a turn-on delay for the first synchronous rectifier switch SR. The controller also includes a discharge switch Q | 07-29-2010 |
20100315839 | ENERGY RECOVERY SNUBBER CIRCUIT FOR POWER CONVERTERS - An energy recovery snubber circuit for use in switching power converters. The power converters may include a switch network coupled to a primary winding of an isolation transformer, and rectification circuitry coupled to a secondary winding of the isolation transformer. The energy recovery snubber circuit may include clamping circuitry that is operative to clamp voltage spikes and/or ringing at the rectification circuitry. The clamped voltages may be captured by an energy capture module, such as a capacitor. Further, the energy recovery snubber circuitry may include control circuitry operative to return the energy captured by the energy capture module to the input of the power converter. To maintain electrical isolation between a primary side and a secondary side of the isolation transformer, a second isolation transformer may be provided to return the captured energy back to the input of the power converter. | 12-16-2010 |
