Abstract: There is disclosed a method and apparatus for estimating the timing position of data bursts received in a data stream. where each data burst includes a number of bits comprising a training sequence in a fixed location. The receiver includes circuitry for estimating the timing position of the data bursts received in the data stream.  For each of the first N received data bursts, the receiver estimates a plurality of timing locations of the training sequence, correlates the training sequence for each estimated timing location, and determines the timing location associated with the highest correlation value. The receiver then determines the average timing location of the highest correlation values for each of the fast N data bursts. For the next M  data bursts the receiver estimates the timing location of each data burst based on the average timing location for the first N data bursts.

Abstract: A modular storage apparatus for movably supporting one or more storage units in front of a plurality of non-movably supported storage units. The apparatus comprises a plurality of independent, modular base sections each having a pair of tracks thereon which are securable together via cam lock coupling devices to form a single, rigid, lightweight, elongated base assembly. A leveling and supporting system associated with each base unit enables the entire base assembly to be precisely leveled. The base units each support at least one carriage unit which in turn supports an independent storage unit thereon. An anti-tip system prevents each movable storage unit from tipping or leaning beyond a predetermined degree. The modular construction enables the apparatus to be easily and conveniently shipped, packaged and handled and the assembled base assembly does not, need to be secured to a supporting floor.

Abstract: A POS terminal determines an upsell to offer in exchange for the change due to a customer in connection with a purchase. The point-of-sale terminal preferably maintains a database of at least one upsel l price and a corresponding upsell to offer a customer in exchange for the change due to him. If the customer accepts the upsell, the cashier s o indicates by pressing a selection button on the POS terminal. The required payment amount for the customer to pay is then set equal to the rounded price, rather than the purchase price. Thus, the customer receives the upsell in exchange for the coins due to him, and the coins need not be exchanged between the customer and the POS terminal.

Abstract: A method and a device for measuring systolic and diastolic blood pressure and heart rate in an environment comprising extreme levels of noise and vibrations is disclosed. Blood pressure signals corresponding to the heart beat are detected using a first acoustic sensor placed on a patient near an artery. A second acoustic transducer is placed on the patient away from the artery for detecting noise and vibrations. Pressure is applied to the artery forcing the artery to close. The pressure is then reduced and while reducing the pressure the acoustic signals detected by the first and second acoustic sensor as well as a signal indicative of the pressure applied to the artery are provided to a processing unit. The signal of the first acoustic sensor is then processed using an adaptive interferer canceller algorithm with the signal of the second acoustic sensor as interferer. From the processed signal heart beat pulses are determined and relating the heart beat pulses to the pressure signal provides the systolic and diastolic blood pressure. Use of the adaptive interferer canceller provides good results for measurements performed under extreme levels of noise and vibrations such as aboard a helicopter.

Abstract: A passive Traffic Alert and Collision Avoidance System (TCAS) and method is based on receiving and processing Mode-S transponder messages without the TCAS computer having to interrogate the transponders of the respective aircraft flying in formation (i.e., a passive TCAS). A TCAS computer and Mode-S transponder are used to provide distributed infra-formation control among multiple cells of aircraft flying in formation or close-in. The Mode-S transponder provides ADS-B Global Positioning System (GPS) squitter data to the TCAS computer; the TCAS computer receives and processes the data without having to interrogate the transponders of the multiple cells of aircraft. The method and system allow a safe separation between 2 to 250 aircraft flying in formation at selectable ranges.

Filed: 1999-08-19
Granted: 2005-03-29
Abstract: The invention relates to a computer-aided system which is capable of displaying component and process structures for configurable product classes, said product classes being stored in a data structure.      Product classes in the data structure are represented by product nodes. Components, which are abstractions of actual items used in the product, are represented by component nodes. Component nodes are mapped onto each product class to which the component is allocated, and are allocated to one or more component variants, these being actual items used in the production of a particular product variant. Process nodes, which are abstractions of actual steps required to produce a product variant, known as process variants, are represented by process nodes. On receiving the selection of a particular product class, the computer-aided system transfers all of the component nodes and process nodes that are allocated to this product class and is able to represent them graphically, for example.      Alternatively, the system receives the input of a product variant and displays all of the component variants used in the production of this product variant, in the form of lists of materials.

Abstract: An information server directs users of the information server to desired sources of information where the desired sources of information are determined, at least in part, based on user input. The information server includes a query input processor, a question processor and an answer processor. The query input processor is used for accepting an initial user query. The question processor processes the initial user query to identify a set of possible well-formed questions selected from the question database, where a well-formed question is a question in the database that is coupled to at least one answer reference. The answer reference is typically either an answer or a pointer to a possible location of an answer. In a specific embodiment, the information server is coupled to the Internet so that users can pose questions using a Web browser from any Internet-connected device. In some systems, the question processor includes a tokenizer for tokenizing the initial user query into a list of words, a parser for generating a syntactic structure from the list of words, a normalizer for reducing the syntactic structure to a canonical syntactic structure, and a matcher for matching the canonical syntactic structure against a semantic network to obtain a weighted list of well-formed questions representative of possible semantic meanings for the initial user query.
