20130189124 | VERTICAL SELF-PRIMING PUMP - The present invention claims a vertical self-priming pump which comprises a pump body, a motor and a medium backflow blocking device, wherein a middle partition plate is provided inside the pump body, and a flow guide body is fixed on the middle partition plate; the motor is fixed on the pump body for driving a pump shaft to rotate; and an impeller that is arranged in the flow guide body is fixed on the lower end of the pump shaft; a backflow gap channel is formed between the outer circumferential surface of the impeller and the inner wall of the flow guide body; and the medium backflow blocking device comprises a static ring and a moving ring which are vertically and oppositely arranged, and an elastic supporting sleeve; the moving ring is embedded on the upper surface of the impeller, the elastic supporting sleeve is fixed on the upper surface of the flow guide body, and the static ring is embedded on the lower surface of an elastic supporting ring. During normal working, the elastic supporting sleeve of the present invention in the medium backflow blocking device generates a downward deformation under the action of liquid medium pressure, thus the moving ring and the static ring closely contact with each other and block the backflow gap channel, therefore the volume loss generated by the backflow is avoided, and the pump efficiency is improved. | 07-25-2013 |

20110231885 | LIVE TIME-SHIFT SYSTEM BASED ON P2P TECHNOLOGY AND METHOD THEREOF - The present invention provides a live time-shift system based on the P2P technology and a method thereof. The system includes a coding server, a live server and a control server arranged at a server end. The method includes: splitting, by the coding server, a received live video data stream into fixed-size live video packets; and then adding live channel information and time information to each of the live video packets; issuing the coded live video packets to the live server, and sending current control information to the control server; continuously obtaining, by the live server, the live video packets from the coding server; upon requesting viewing of the video data, first sending, by the client, a video request to the control server; returning, by the control server, storage information of the video data to the client, and obtaining, by the client, the video data through an established data link. Both of the server and the client of the present invention support the live time-shift function based on the P2P technology, which may support mass parallel applications. | 09-22-2011 |

20120136633 | OPTIMIZATION-BASED SIMULATED ANNEALING FOR INTEGRATED CIRCUIT PLACEMENT - Generating of the initial temperature value for a simulated annealing process in the placement of circuit components in the physical design of integrated circuit (IC) is based on previous partitioning, if any, of the IC components into bins. An iteration limit value is then assigned equal to the initial temperature value. The simulated annealing process is then performed on a current partitioning of the IC components into bins according to the iteration limit value. The IC components are partitioned further into an exponentially larger total number of smaller bins compared to a previous number of bins. The process is then repeated starting with the operation of generating an initial temperature value for the simulated annealing process until the number of circuit components in each bin is below a specified number. | 05-31-2012 |
