  • Publication number: 20120290526
    Abstract: A computer-based system and method to improve the multimodal fusion output at the decision level is disclosed. The method proposes computation of a confidence weighted measure for the individual score values obtained for each modality and fuse these new updated scores to get the final decision. These confidence weights are the performance parameters (measured in terms of F-measure) during the offline training step. The process significantly increases the accuracy of the multimodal system.

  • Patent number: 8302969
    Abstract: This invention describes a game of inverse chess, with a pre-identified start position, and end position and arbitered moves chosen amongst a set of possible moves, played between two opponents on a chess board. This differs from normal chess in that it is played backwards in time where the objective is to reconstruct the pre-identified start position, from the pre-identified end position. While the pieces used in the game are essentially the same as that of regular chess, the moves they make are reversed. Since the state-space of this game is much larger in the potential moves, an arbiter is used to validate possible moves that one player might choose to make. Using either a regular or modified chess board, the pieces on the board move backwards. Three such moves are described in the I-castle, spawn and I-check moves. A variant of the game is the two-knight game wherein two knights play each other and the piece reaching the pre-identified start position, win.

  • Publication number: 20120170699
    Abstract: A method and mechanism for reducing lock time of a dual-path phase lock loop (PLL). The PLL comprises a dual-path low-pass filter (LPF). The LPF includes a first filter and a second filter. The first filter comprises a passive second-order lead-lag low-pass filter. The second filter comprises a first-order lag low-pass filter. During a lock-acquisition state, an impedance value within the second stage is bypassed, which increases the loop bandwidth of the PLL. In addition, a resistance within the first stage is increased in order to increase the gain of the first stage and maintain stability within the PLL. During a lock state, the impedance value may no longer be bypassed and the increased resistance may be returned to its original value.

  • Patent number: 8206425
    Abstract: A cranial fixation system and method are provided. The system includes two heads slidably connected with telescopic extensions and a spring or an elastomeric flexible component. The two heads are maintained in a distracted position by a locking mechanism until ready for cranial implantation. Once implanted, the locking mechanism is disengaged, thereby allowing the heads to compress towards each other by the spring and approximate the cranial bone flap to the skull.

  • Patent number: 8207983
    Abstract: The embodiments of the present disclosure teach overlaying videos on a display device. The technique involves one or more buffers at input such as a first buffer (Primary Buffer) and an overlay buffer, a blitting module, a second buffer(Frame Buffer), and a display screen. The first buffer provides a first image data to the blitting module and the overlay buffer provides a second image data to the blitting module. The embodiments of the present disclosure demonstrate overlaying the second image on the first image with enhanced configurable functionality (like stretching, clipping, color keying, Alpha Blending and Raster Operation) if required, without modifying the Primary Buffer without the need of any overlay support in hardware.

  • Publication number: 20110223111
    Abstract: A facile method to synthesize stable calcium carbonate microstructures is demonstrated which allows in situ encapsulation of sensitive molecules like drugs. The methodology involves a macromolecular assembly of anionic polypeptide with cationic peptide oligomer to concurrently template and hold to stabilize the mineralized structure. The heterogeneously distributed mixture of anionic and cationic residues in the macromolecular assembly, similar to that is found in natural systems assists in recognizing and coassembling Ca2+ and CO32? ionic clusters, especially for formation of a disordered precursor phase such as amorphous calcium carbonate (ACC) and further crystallization to form a metastable vaterite phase. The assembly also facilitates encapsulation of a guest molecule such as tetracycline at ambient conditions without affecting the mineralization process.

  • Publication number: 20110111383
    Abstract: The present invention relates to a system used for competency assessment of candidates. More particularly the present invention relates to an automated system for talent acquisition in an enterprise to identify talented candidates who meet the qualification standards specified by enterprise using a secured and light weight method of providing content including questions and responses in a distributed architecture. The data centre server of the system may connect to Knowledge centre server to receive the secure test content. The test content is transferred to one or more exam centre servers from the data centre server. The exam centre servers assess the competency of candidates connected to them via candidate console devices (computational devices), by generating unique and standardized test content for each candidate. The system enables less effort, time and consequently money, that multiple test administrators may spend traveling to different test locations to support the system infrastructure.
