  • Patent number: 8916627
    Abstract: The present invention is directed to the use of continuous extrusion devices to form high quality polymer dispersions of polyvinyl butyral), a surfactant, and a plasticizer. Screw extruder devices of the present invention inject water into a zone of high pressure, temperature, and shear to cause the rapid inversion of a weld in less than, for example, one minute, which compares very favorably with conventional batch methods, which can take, for example, two or more hours to complete an inversion. This rapid inversion—a surprising result given the extended time inversion requires in batch processes—allows for the continuous production of poly(vinyl butyral) dispersions.

  • Patent number: 8166377
    Abstract: The present invention discloses a configurable hierarchical comma-free Reed-Solomon decoding circuit and a method thereof. The design is based on an original hierarchical parallel architecture which not only completes a decoding process faster than conventional decoder, but also utilizes less hardware to perform various algorithms with less power consumed. The architecture of the present invention has higher decoding rate than the conventional systolic architecture by a cycle ratio of 22 to 94. Further, the present invention does not require the use of ROM to store 64 sets of codewords and uses logic gates less than one fourth of the logic gates than conventional systolic architecture. As a result, the circuit of the present invention occupies less area than the conventional architecture. The circuit of the present invention is also configurable for different applications, so it can always find an optimal compromise between speed and power consumption for various decoding requirements.

  • Patent number: 8000352
    Abstract: A synchronizer for a communication device and an access point, which is installed inside the communication device and comprises a coefficient generator generating a set of coefficient code. A parallel-to-serial converter receives a set of input code from an access point, performs a parallel-to-serial conversion on the set of input code and outputs a result. A coefficient element array includes a plurality of coefficient elements interconnecting with each other. Each of the coefficient elements receives the set of input code from the parallel-to-serial converter and receives the set of coefficient code, and then performs a passive or active correlation operation on the set of input code and the set of coefficient code to output a correlation value to the access point for synchronizing signals of the communication device and the access point.
