摘要： The present invention relates to an apparatus and method for generating compressive measurements of video using spatial-temporal integration. The apparatus includes a detector configured to detect luminance values of a temporal video structure over a period of time based on optical data. The temporal video structure has pixels with a horizontal dimension and a vertical dimension with corresponding luminance values over the period of time. The apparatus also includes a spatial-temporal integrator unit configured to receive a plurality of measurement bases. Also, the spatial-temporal integrator unit is configured to apply each measurement basis to the temporal video structure and to sum resulting values for each measurement basis over the period of time to obtain a set of measurements.

摘要： Example embodiments are directed to methods of ensuring high availability of a network using asynchronous checkpointing of application state data related to an object. Example embodiments include a method of asynchronous checkpointing application state data related to at least one object, including receiving application events and processing the application events to obtain new application state data. The method further includes modifying at least a portion of previously stored application state data and asynchronously and independently checkpointing the modified application state data based on whether the modified application state data has reached a stable state. Example embodiments also include a method of ensuring consistent application state data across a network. This method may include having at least two CAPs independently and asynchronously storing application state data related to at least one object at two different network nodes and automatically auditing the stored application state data to ensure data consistency.

摘要： A method is disclosed for decoding multiple-coded symbols from a coded input symbol stream in a single clock cycle. The method constructs an original Huffman look-up table by extending the associated Huffman tree to decode multiple symbols in one clock cycle in a first embodiment and decodes multiple DCT coefficient symbols in an alternate embodiment. An advantage of the method is that the depth of the new Huffman tree is adjustable thereby making the method easily adaptable to various hardware architectures. A further advantage of the present invention is that the decoding process speed is significantly increased while the size of the lookup table is nominally increased.
