20150053568 | HETEROJUNCTION ELEVATED-TEMPERATURE PHOTOELECTROCHEMICAL CELL - A solid-state PEC includes mixed ionic and electronic conducting oxides that allow it to operate at temperatures significantly above ambient utilizing both the light and thermal energy available from concentrated sunlight to dissociate water vapor. The solid-state PEC has a semiconductor light absorber coated with a thin MIEC oxide for improved catalytic activity, electrochemical stability and ionic conduction, which is located between the gas phase and the semiconductor light absorber. As a result, the MIEC oxide provides a facile path for minority carriers to reach the water vapor as well as a path for the ionic carriers to reach the solid electrolyte. Elevated temperature operation allows reasonable band misalignments at the interfaces to be overcome, reduces the required overpotential, and facilitates rapid product diffusion away from the surface. | 02-26-2015 |

20100315152 | CONTROL METHOD FOR SOFT SWITCH CIRCUIT IN SWITCH POWER SUPPLY - The present invention relates to a control method for a soft switch circuit in a switch power supply, which controls first and second main power switch devices to be turned on and turned off constantly to generate an alternating main power filter current, and controls forward and backward auxiliary switch devices to be turned on and turned off to generate an intermittent alternating resonant current across a resonant branch in the same direction as the main power filter current to thereby achieve zero-voltage turn-on of the first and second main power switch devices; and further controls the forward and backward auxiliary switch devices to be turned on and turned off to generate compensation currents across the resonant branch in the opposite direction to the alternating main power filter current in at least a period of time during resting of the resonant current to thereby accomplish a charging and discharging process of resonant capacitors in a dead time. Thus, a freewheeling diode can be turned on normally, so that it is possible to avoid a damage to the devices due to an impact current and a spark voltage resulting at zero crossing of the current in the soft switch circuit. | 12-16-2010 |
20110278953 | CONTROL METHOD FOR SOFT SWITCH CIRCUIT IN SWITCH POWER SOURCE - The present invention discloses a control method for a soft switch circuit in a switch power source, which generates an alternating primary power filter current by controlling first and second primary power switching devices to be closed and opened, and generates an intermittent alternating resonant current in the same direction as the primary power filter current in a resonant branch by controlling forward and backward auxiliary switching devices to be closed and opened to thereby achieve closing of the first and second primary power switching devices at a zero voltage, and which generates a balance current with the same magnitude as and in the opposite direction to the resonant current in the resonant branch in at least a period of time during the resting of the resonant current by further controlling the forward and backward auxiliary switching devices to be closed and opened to thereby achieve an average current of zero across the resonant branch in a switching cycle. Without any additional balance circuit, this control method can address the imbalance problem of output power of the positive and negative direct current input voltage sources in a soft switch circuit of an existing switch power source. | 11-17-2011 |

20150052083 | METHOD AND DEVICE FOR RAPIDLY EDITING SENDING CONTENT BASED ON A RECEIVER - A method and a device for rapidly editing sending content based on a receiver. A sending-content-learning module is used to learn sending content to generate a content fragment for a receiver, and perform word frequency statistics on the content fragment; a corresponding list is generated from receiver information, the content fragment, and the word frequency statistics, and is stored; for the receiver and the word frequency statistics, the content fragment is displayed for a sender to edit the sending content, so as to send the sending content to a corresponding receiver. When a user edits a short message or an email, a content fragment commonly used for a corresponding receiver is displayed in a display box, and a sender can rapidly complete editing by selecting a required content fragment, thereby facilitating fast and convenient input and improving the user experience. | 02-19-2015 |
