  • Patent number: 8300697
    Abstract: The proposed Dynamic Motion Vector Analysis method applies to the motion compensation module of a video decoder system. The method analyzes the motion-vectors of a given region of picture frame and outputs a set of regions to be fetched from the reference frames stored in the external memory. The size and number of regions are decided by a hierarchical method that uses a set of user-defined input thresholds. Pre-processing of the motion vectors associated with the given region allows the method to handle reference data to be fetched from multiple reference frames in the same framework. A complementary dynamic batch (region of operation) size strategy that works along with MV-analysis is also proposed to help utilize the on-chip memory resources more efficiently.

  • Patent number: 7336699
    Abstract: A system and method are provided for determining whether a chipping code from a group of codes is used in a signal. In one embodiment of the invention, a signal is received and each code from the group is correlated with the received signal. The ratio of the highest correlation value to the second highest correlation value is calculated. If the ratio exceeds a threshold, the chipping code may be determined as the chipping code used in the signal. In another embodiment, the ratio of the highest correlation value and the total received power of the signal is calculated. If the ratio exceeds a threshold, the chipping code may be determined as the chipping code used in the signal.

  • Patent number: 7277474
    Abstract: A technique for allocating fingers in a path searcher of a multipath receiver involves determining a required number of fingers for each multipath region, determining a number of allocated fingers for each multipath region according to an area-based weighting scheme such that each multipath region that is allocated fewer than its required number of fingers is deemed to have a non-zero residual area, allocating any surplus fingers to multipath regions having non-zero residual areas until either no surplus fingers remain or each multipath region is allocated its required number of fingers, and placing any fingers allocated to each multipath region within the multipath region. Placing the fingers in un-resolvable path scenario involves detecting path location at the edges of multipath region; placing fingers at the edges and placing remaining fingers uniformly between the first and the last path such that the there is a minimum placement separation between the fingers.

  • Patent number: 7005297
    Abstract: The invention relates to a novel use of neuroactive compounds by treating the fruitfly Drosophila melanogaster adult males with fly medium containing either of the neuroactive compounds strychnine, pentylenetetrazol, tetraethylammonium chloride, lithium carbonate and nicotine, crossing the drug treated males with untreated females to obtain progenies and self-crossing the progenies to obtain grand progenies, observing the locomotor behavior of the parents and their progenies and grand progenies in terms of height climbed in a negative geotaxis assay, wherein an altered height climbed by parents and their progenies and grand progenies, compared to those of normally fed males, demonstrates that the neuroactive compounds produce inheritable behavioral change.

  • Publication number: 20050144654
    Abstract: The invention relates to a procedure for screening of neuroactive substance and the associated neural plasticity by treating fruitfly Drosophila melanogaster adult males with fly medium containing either of the neuroactive compounds strychnine, pentylenetetrazol, pilocarpine hydrochloride, tetraethylammonium chloride, lithium carbonate and ethosuximide, subjecting flies to negative geotaxis and horizontal locomotor assays, observing the height climbed and distance walked by and the climbing speed of the flies wherein an altered height climbed by flies under drug treatment and a long-lasting alteration in climbing speed of flies after drug withdrawal is most characteristic of the neuractive compounds.

  • Patent number: 6291739
    Abstract: The invention relates to a method for screening anti-epileptic drugs using fruit fly Drosophila melanogaster by generating single and double mutant lines of K+ channel genes in Drosophila melanogaster, culturing mutant lines on Drosophila medium under standard conditions, identifying the mutants, separating male flies under ether anesthesia, supplying the mutant males with medium containing each of the four antiepileptic drugs, phenobarbital, phenytoin, carbaamazepine and valproate, separately, administering ether anesthesia to the drug treated flies and examining their leg shaking intensity under stereomicroscope, observing the antiepileptic effect in the drug treated males wherein a reduced intensity of leg shaking, compared to leg shaking in normally fed etherized males, is indicative of antiepileptic activity in the drug.
