Title: Method and system for high-spread high-distance interleaving for turbo-codes
Inventor: CROZIER STEWART N
IPC: H03M13/27
Filed: 2001-05-25
Abstract: A system and method are provided for designing high-spread, high-distance interleavers for turbo-codes. The first approach is called high-spread random interleaving, and is based on a new and more effective definition of interleaver spread. The second approach is called dithered-diagonal interleaving. Both methods can be used to design interleavers of arbitrary length. The second approach can actually achieve the theoretical maximum spread for many specific block sizes, and at the same time include significant dither for the elimination of low-weight codewords. Both design methods are easy to implement and require very little processing. Also provided is a method for modifying any interleaver to improve the distance spectrum for a specific turbo-code. It is shown that, for a block size of only 512 data bits and for a code rate of 1/3, the flares in the packet error rate (PER) and bit error rate (BER) curves can be kept below 10 -8 and 10 -10, respectively.

Title: Non-corrosive peroxy carboxylic acid-based sterilant composition
Inventor: SWART SALLY K
IPC: A61L2/18
Filed: 1999-11-22
Abstract: A non-corrosive, liquid, aqueous sterilant composition (as a concentrate or ready-to-use solution), which may be provided in two parts which are mixed prior to application, may comprise a peracid (in an equilibrium solution with an underlying carboxylic acid or mixtures of alkyl carboxylic acids and peroxide), inorganic buffering agent, and water. It has been found that the use of this simplified system, even in the absence of additional components which have been thought to be desirable for sterilants used on metal parts (e.g., copper and brass corrosion inhibitors, chelating agents, anti-corrosive agents) display excellent performance and that these additional components are not necessary, and that the presence of these additional materials at least complicates disposal of the spent solutions and could complicate compatibility of the sterilant solutions with some polymeric materials, especially where organic materials are used as the additional components, which organic materials may interact with, dissolve or solubilize in the polymeric materials.

Filed: 2001-12-20
Abstract: Embodiments of the invention include a testing measurement which output a non-binary test result for one or more steps or processes performed during execution of a test of a subject. The non-binary test result, which may be output by a verification point or a test script, provides a developer with an improved gauge of the subject under test. In embodiments of the present invention, a test script or verification point will, rather than simply generate a "pass" or "fail" (i:e., "successful" or "unsuccessful") output, generate a non-Boolean value providing data with improved correlation between the test output and the relative success of a test script. In some embodiments, each verification point or test script can be associated with a rule for determining the test output which can be easily modified. This aspect provides users with an ability to carefully develop and implement a test result rule which provides output which enhances test output data analysis.

Abstract: A system which provides session oriented communications between a settop terminal and a headend of a CATV communication system assigns downstream and upstream communication paths to the communication. A data router monitors the downstream communication path and re-routes the downstream communication path when a channel change is requested by a subscriber. The settop terminal notifies the data router that a channel change has been requested by the subscriber. The router re-routes the downstream portion of the data communication to the new channel requested by the subscriber, thereby insuring an uninterrupted data communication session.
