20140196055 | HIGH PERFORMANCE LOG-BASED PROCESSING - Each of a plurality of Worker processes are allowed to perform any and all of the following tasks involving logged work items: (1) reading a subset of the work items from a log; (2) sequentially ordering work items for corresponding data objects; (3) applying a sequentially ordered set of work items to a corresponding data object; and (4) transmitting a subset of work items to a Worker process running on another database server in a cluster, if necessary. These tasks can be performed concurrently, at will, and as available, by the Worker processes. An improved checkpointing technique eliminates the need for the Worker processes to get to a synchronization point and stop. Instead, a Coordinator process examines the current state of progress of the Worker processes and computes a past point in the sequence of work items at which all work items before that point have been completely processed, and records this point as the checkpoint. | 07-10-2014 |

20140301655 | IMAGE DECODING METHODS AND IMAGE DECODING DEVICES - Image decoding methods are provided. First, an input bitstream corresponding to an image is acquired and an entropy decoding operation is performed on a block to be decoded in the input bitstream to obtain a decoding result, wherein the decoding result includes at least one coefficient having a corresponding block position information and coefficient value. It is then determined whether the coefficient value of the at least one coefficient is zero. When the coefficient value of the at least one coefficient is not zero, the at least one coefficient is determined as an non-zero coefficient and the block position information and coefficient value corresponding to the non-zero coefficient are stored to an external storage device. When the coefficient value of the at least one coefficient is zero, the block position information and coefficient value corresponding to the at least one coefficient are not stored. | 10-09-2014 |

20140331346 | CONTROLLABLE ON-OFF METHOD FOR FISH REPRODUCTION - The invention discloses a method for controlling fish reproduction, the method comprises the following steps of: A, constructing a recombinant gene CMV-eGFP-SV40-CMV-Ga14-SV40 and establishing a GAL4 transgenic zebrafish line; B, constructing a recombinant gene CMV-RFP-SV40-UAS-antisense dnd and establishing a uas-antisensednd transgenic zebrafish line; and C, hybridizing by taking homozygous transgenic fish of the two lines as parents, and the hybrid generation fish was sterility. The method of the present invention takes a strategy that two fertilizable lines hybridized but hybrid generation is sterility, establishing a novel method with a universal meaning for controlling fish fertility; The method solves the contradiction of the reproductively sterility of fish and the hereditability of characters in a reproduction operation research and can be effectively applied to cultivation of new fish specie and population control. | 11-06-2014 |

20140345395 | TESTING SYSTEM FOR TESTING A PORTABLE ELECTRONIC DEVICE - A testing system includes a base, a frame installed on the base, a platform, a first driving mechanism, a second driving mechanism, a locating component, a third driving mechanism and a control unit. Two guiding tracks and a sliding component which slides along the two guiding tracks are disposed under two sides of the platform. The second driving mechanism is connected to the sliding component, and the third driving mechanism is disposed on the sliding component and connected to the locating component. The control unit is for controlling the first driving mechanism to drive the platform to move in a first direction, so that the locating component presses a portable electronic device disposed on the base. The control unit is further for controlling the second driving mechanism and the third driving mechanism to drive the locating component to move in a second direction and a third direction. | 11-27-2014 |

20160026801 | METHOD AND SYSTEM PROVIDING MUTLI-LEVEL SECURITY TO GATE LEVEL INFORMATION FLOW - A preferred method for providing multi-level security to a gate level information flow receives or specifies a security lattice having more than two security levels. The security lattice defines how security levels relate to each other. A hardware design implementing information flows including flows having security levels specified by the security lattice is received. Logic is created for testing the hardware design in view of the security lattice. A logic function is created based upon the hardware design and the logic for testing to implement the security lattice. Another method receives a hardware design in a hardware description language. At least a portion of the hardware design is synthesized to gate level primitives. Functional component tracking logic supporting more than two-security levels is built from the gate level primitives. Functional components in the hardware design are simulated with the functional component tracking logic. | 01-28-2016 |

20160089975 | VEHICLE AND SEMI-AUTOMATIC FOOT-PEDAL DEVICE THEREOF - A semi-automatic foot-pedal device is provided, which comprises a panel and a pedal-connecting component connected with the panel. The pedal-connecting component comprises an upper bracket, a left bracket, a lower bracket, a right bracket and an elastic unit; when the pedal-connecting component is in a closed state, the panel moves away from the upper bracket to transform the pedal-connecting component into an elastically spread state under a force on the panel in a downward direction; when the pedal-connecting component is in a spread state, the panel moves towards the upper bracket to transform the pedal-connecting component into an elastically closed state under a force on the panel in an obliquely-upward direction. The semi-automatic foot-pedal device of the present disclosure has a novel structure, and does not need a conventional motor system, so it saves the electric power and is safer to use. | 03-31-2016 |
