  • Patent number: 8934665
    Abstract: A method and apparatus for tracking an object, and a method and apparatus for calculating object pose information are provided. The method of tracking the object obtains object feature point candidates by using a difference between pixel values of neighboring frames. A template matching process is performed in a predetermined region having the object feature point candidates as the center. Accordingly, it is possible to reduce a processing time needed for the template matching process. The method of tracking the object is robust in terms of sudden changes in lighting and partial occlusion. In addition, it is possible to track the object in real time. In addition, since the pose of the object, the pattern of the object, and the occlusion of the object are determined, detailed information on action patterns of the object can be obtained in real time.

  • Publication number: 20140104375
    Abstract: Embodiments of the present invention provide a state transition control method, a multipoint control server, and a videoconferencing system. The method includes: receiving, by a multipoint control server, a conference reservation message, where the conference reservation message carries start time and end time of a reserved conference and an identity of a site centralized control device at a site participating in the reserved conference; and sending a state transition command to the site centralized control device according to the start time and the identity or according to the end time and the identity. In the embodiments of the present invention, through centralized control, in a non-conference state, external devices in a videoconferencing system enter a power-off state, and in a conference state, devices in the videoconferencing system are recovered to a normal working state, thereby improving user experience and reducing power consumption of the videoconferencing system.

  • Publication number: 20130346707
    Abstract: Resource use is recorded with a partitioned reference counter. The sum of all resource counter partitions is equivalent to the total references to a resource. When one resource counter partition reaches zero, it is possible that the resource should be destroyed. To determine if this is the case, all other partitions can be checked for a value of zero. If all the partitions are zero, the resource can be destroyed. Coarse grained partitioning and add/release on all partitions can be employed to avoid extra work associated with a local partition reaching zero. Further, destroying or deleting a resource can be accomplished in a manner that avoids a race condition.

  • Publication number: 20130224198
    Abstract: A recombinant fusion protein comprising a human erythropoietin peptide portion linked to an immunoglobulin peptide portion is described. The fusion protein has a prolonged half-life in vivo compared to naturally occurring or recombinant native human erythropoietin. In one embodiment, the protein has a half-life in vivo at least three-fold higher than native human erythropoietin. The fusion protein exhibits enhanced erythropoietic bioactivity compared to native human erythropoietin. In one embodiment, the fusion protein comprises the complete peptide sequence of a human erythropoietin (EPO) molecule and the peptide sequence of an Fc fragment of human IgG1, which Fc fragment includes the hinge region, CH2 and CH3 domains. The EPO molecule may be linked directly to the Fc fragment to avoid extraneous peptide linkers and lessen risk of an immunogenic response when administered. In one embodiment the hinge region is a human Fc fragment variant having a non-cysteine residue at amino acid 6.

  • Patent number: 8401130
    Abstract: A system and method are provided for automatic gain control (AGC) using an adaptive reference and a threshold. An adaptive reference allows for adjusting the target power based on variations in operating parameters and conditions, such as a change to a modulation schemes which requires a different signal to noise ratio (SNR) to maintain performance. A gain adjustment threshold allows for rapid AGC response while reducing the potential effects of hysterisis. AGC levels may be changed during symbol prefixes or suffixes, and avoided during a data portion of a signal. Embodiments allow for symbol-by symbol AGC changes in OFDM, OFDMA, and TDD systems.

  • Publication number: 20120100099
    Abstract: A fusion protein having a non-immunoglobulin polypeptide having a cysteine residue proximal to the C terminal thereof, and an immunoglobulin component with a mutated hinge region is provided. The mutation comprises a point mutated site corresponding in position to the position in a native hinge region of the cysteine residue located nearest the cysteine residue of the non-Ig component. The distance from the cysteine residue of the non-immunoglobulin polypeptide and any remaining cysteine residues of the mutated hinge region is sufficient to prevent the formation of a disulphide bond therebetween.
