  • Publication number: 20090285473
    Abstract: Machine-readable media, methods, apparatus and system for obtaining and processing image features are described. In some embodiments, groups of training features derived from regions of training images may be trained to obtain a plurality of classifiers, each classifier corresponding to each group of training features. The plurality of classifiers may be used to classify groups of validation features derived from regions of validation images to obtain a plurality of weights, wherein each weight corresponds to each region of the validation images and indicates how important the each region of the validation images is. Then, a weight may be discarded from the plurality of weights based upon a certain criterion.

  • Publication number: 20090279334
    Abstract: A switching power supply includes a rectifier circuit, a converter, a detecting unit, a control unit, a switching unit, and a protection unit. The rectifier circuit is used for rectifying an input voltage into a first direct current voltage. The converter is configured for generating a first current according to the first direct current voltage. The detecting unit is used for generating a detected voltage according to the first current. The control unit is configured for generating a control signal. The switching unit is used for enabling the converter, and conducting the first current to the detecting unit when receiving the control signal. The protection unit is configured for shunting the first current with the detecting unit when the first current becomes a large current surge. The control unit stops generating the control signal when determining that the detected voltage is equal to or higher than a predetermined value.

  • Patent number: 7612014
    Abstract: The present invention addresses at least four different aspects relating to catalyst structure, methods of making those catalysts and methods of using those catalysts for making alkenyl alkanoates. Separately or together in combination, the various aspects of the invention are directed at improving the production of alkenyl alkanoates and VA in particular, including reduction of by-products and improved production efficiency. A first aspect of the present invention pertains to a unique palladium/gold catalyst or pre-catalyst (optionally calcined) that includes rhodium or another metal. A second aspect pertains to a palladium/gold catalyst or pre-catalyst that is based on a layered support material where one layer of the support material is substantially free of catalytic components. A third aspect pertains to a palladium/gold catalyst or pre-catalyst on a zirconia containing support material.

  • Publication number: 20090269022
    Abstract: A method, apparatus and system for, for each of a plurality of image frames, assigning a pattern number to each of a set of pixel neighborhoods within the frame and assigning a relationship number to each of a plurality of sets of pattern numbers based on a probability of transitioning between different pattern numbers in the set of pattern numbers when transitioning between different pixel neighborhoods. For a subset of the plurality of frames, the subset of frames may be determined to be similar, for example, based on the similarity of the relationship numbers of the subset of the plurality of frames. Other embodiments are described and claimed.

  • Publication number: 20090267411
    Abstract: A regulator includes a power-converting circuit and a protection circuit. The power-converting circuit is for converting a primary voltage to a secondary voltage. The protection circuit is coupled to the power-converting circuit. The protection circuit receives the primary voltage earlier than the power-converting circuit. When a voltage spike of the primary voltage occurs, the protection circuit shunts the high instantaneous voltage to ground. An electrical device and a car using the regulator is also provided.
