Title: Code structure, encoder, encoding method, and associated decoder and decoding method and iteratively decodable code structure, encoder, encoding method, and associated iterative decoder and iterative decoding method
Inventor: HUNT ANDREW WILLIAM
IPC: H03M13/29
Filed: 2001-07-06
Granted: 2009-11-10
Abstract: A class of codes and associated methods and devices are provided. Advantageously, such codes when used as constituent codes in composite codes intended for iterative decoding, as compared to the standard practice of using convolutional codes, may allow better error-correcting performance to be achieved, especially at low error rates and high code rates, for a given decoder complexity. State sequencing in these codes is driven not by source data alone, as is the case with convolutional codes, but rather by a sequence that includes both the source data and so-called "inserted" data elements, the inserted data elements having a linear dependence on the state sequencing state. In decoding, state transition intervals involving one or more inserted data elements are handled in a special way.

Abstract: A endoscopic multiple sample biopsy forceps is disclosed having a jaw assembly with a pair of jaws connected to a pair of arms extending from a jaw housing. Each jaw has two shanks oppositely displaced from the longitudinal axis of the device to define a space in the rear of the jaw for storing collected tissue samples. The tissue storage space defined by the jaw shanks opens rearwardly into a tissue storage area defined within the housing. Each shank has a broad outwardly facing planar surface aligned with an inwardly facing planar surface on one of the pair of arms. A  cam slot on each jaw shank is slidably engaged by a cam pin on one of the pair of arms.  A puller member coaxially positioned in the housing and axially movable relative to the housing supports a pair of pivots, each of which pivotally engages a bore on at least one jaw shank. The puller member is attached to a drive wire coaxially positioned in a tubular shaft. Axial movement of the drive wire actuates the puller member. In response to axial movement of the puller along the longitudinal axis of the outer tube, the cam pins riding in the cam guide slots change the position relative to the fixed jaw pivot axis of the jaw, thus actuating the jaws. None of the jaw assembly elements movable relative to the device, except the jaws, are externally exposed such that they could contact targeted tissue and negatively affect tissue sampling operations. An ejector is provided to push collected samples from the tissue sample storage area.

Abstract: A pneumatic fastener-driving tool is disclosed wherein not only rapid-fire bump-firing or trigger-firing modes of operation are permitted wherein either one of the trigger member and workpiece contact element components can be depressed before the other one of the trigger member and workpiece contact element components depending upon the particular mode of operation that the operator personnel chooses to employ, however, the tool is also rendered safe for transportation by operator personnel between job sites or work sites in view of the fact that if the workpiece contact element is not depressed, as a result of not being disposed in contact or engagement with a workpiece, within a predetermined period of time subsequent to the performance of the last fastener discharge or firing operation, then the tool is pneumatically disabled and can only be again enabled if the proper sequential activation of the tool is performed wherein the workpiece contact element must be engaged with a workpiece prior to the depression or activation of the tool trigger. Accordingly, after the expiration or lapse of the aforenoted predetermined period of time, should the operator personnel carry or transport the tool with the trigger member nevertheless depressed, the tool will not fire or discharge a fastener even if the workpiece contact element is depressed due to the fact that the tool has already been pneumatically disabled.

Abstract: The invention relates to a method and apparatus for generating translations of natural language terms from a first language to a second language. A plurality of terms are extracted from unaligned comparable corpora of the first and second languages. Comparable corpora are sets of documents in different languages that come from the same domain and have similar genre and content. Unaligned documents are not translations of one another and are not linked in any other way. By accessing monolingual thesauri of the first and second languages, a category is assigned to each extracted term. Then, category-to-category translation probabilities are estimated, and using said category-to-category translation probabilities, term-to-term translation probabilities are estimated. The invention preferably exploits class-based normalization of probability estimates, bi-directionality, and relative frequency normalization. The most important applications are cross-language text retrieval, semi-automatic bilingual thesaurus enhancement, and machine-aided human translation.

Abstract: A Municipal Waste Gasification System whereby Municipal Solid Waste (MSW) and other forms of waste are converted to useful energy via a close coupled gasification process in an artfully designed Waste Conversion and Recycling Vessel (WCRV) that allows for precise control of the temperature and oxygen content of the batch waste charge while providing for the automatic sorting of all post-gasification residuals. Embodied in the present invention is a Key Accelerant Balancing System (KABS) that precisely controls the temperature in the range of 800-1100°F and oxygen concentration in the 5-7% range within the WCRV continuously for 12-14 hours yielding overall better efficiency of the conversion of the waste to gas and minimizes pollutants in the present invention. The concrete structure that supports the WCRV doubles as a thermal envelope from which hot air is drawn from to dry the incoming waste. The residual glass, aluminum and other metallic components of the waste are automatically sized and separated from the ash for recycling by a logic control system of gravity doors, vibrating super-magnetized grates, vacuuming, screening and eddy currents advantageously increasing the speed, safety and efficiency of the gasification and automatic recycling of unsorted MSW into energy and marketable raw materials. The gas produced in the waste conversion vessel is conditioned in a unique fuel preparation cell by mixing with ambient air or oxygen and can be used to fire the waste conversion vessel's heating elements with the excess gas or used to run a gas fired turbine or boiler to produce electricity with the residual heat used for district heating, or industrial processes.

Abstract: Opposite ends (11, 35) of strut (10) engage opposed shoes of a drum brake.  During braking, strut (10) is free to lengthen to compensate for brake lining wear. Leaf spring (24) pressing against neck (29) of nut (27) tends to extend strut (10), however this extension is opposed by the engagement of foot (40) of arm (37) with axially disposed face (32) of nut (27). Due to a resilient pivoting action of, and oblique positioning of, arm (37) with respect to cam teeth (31) on face (32) such extension forces are converted into turning of nut (27), leading to axial extension of screw (33) and thus extension of strut (10). Reverse rotation of nut (27) upon release of braking is opposed by frictional contact between it and leaf spring (24).
