  • Patent number: 8340448
    Abstract: A coding method, apparatus, and storage media with instructions to carry out a method. The method operates on an ordered series of transform coefficients of a block of image data, and for a fixed quantization method, and includes quantizing and encoding the ordered series to form a coded bitstream. The quantizing and encoding uses one or more variable length code (VLC) mappings. The quantizing includes quantizing to have amplitude-1 at least one coefficient that would be quantized by the fixed quantization method to have zero amplitude, quantizing to have zero amplitude at least one coefficient that would be quantized by the fixed quantization method to have amplitude-1, and using the fixed quantization method to quantize any coefficient that is quantized by the fixed quantization method not to have zero amplitude, amplitude-1, or amplitude-2.

    Abstract: A pen transcription system and method for locating a moveable signal source are disclosed. The transcription system includes a base having a planar base surface, first and second acoustical sensors that detect an acoustical signal emitted by a moveable signal source, the acoustical sensors being mounted on the base and separated from one another.

  • Patent number: 8279341
    Abstract: In particular embodiments, a process relating to the creation of a high-resolution video from a low-resolution video. In a particular embodiment, the process receives as input a sequence of low-resolution video frames. The process first determines a matching score for consecutive frames in the sequence, where the matching score is based on a preliminary global transformation between consecutive frames. From the matching scores, the process determines a set of matching windows and relative-motion estimates and then uses the set and estimates to calculate more thorough global transformations and any residual relative-motion which can be explained using independent object motion and/or optical flow. The process uses the latter global transformation and any independent object motion and/or optical flow to create motion trajectories and to generate high-resolution frames by interpolating low-resolution frames at trajectory-defined points, using regular-to-irregular spatio-temporal interpolation.

  • Patent number: 8184564
    Abstract: A method, a software product, and an apparatus to operate in a wireless device of a wireless network. The wireless device acts as a plurality of APs. The method includes transmitting bursts of management frames containing a broadcast-buffered indication for a corresponding subset of network identifiers of the wireless device, and transmitting bursts of management frames not containing any broadcast-buffered indication.
