Abstract: A conveyor belt structure (10) has a pair of longitudinally extending tracks or stringers (11) upon which trolleys can ride. A power pack trolley (12) also rides stringers (11). The trolley (12) has stringer-engaging wheels (14) and a power pack supported upon a frame. The power pack might be a rechargeable battery or a generator for example. The power pack trolley (12) also includes a motor or motors to drive its wheels (14). A captivation (30) is affixed to a bogie arm (31). Attached to the lower edge of the mounting plate (32) is a horizontal plate (34). A flange (36) is angularly offset with respect to the plane of the plate (35). Should one of the wheels (17) of the trolley (16) become derailed from stringer (11), one or both of plates (34 and 35) of the captivation bracket (30) will strike the stringer (11).

Abstract: A method for enhancing gas or oil production by delivering a nitrogen rich gas produced from a non-cryogenic source into the well and/or reservoir where the gas and/or oil is located.

Abstract: An information processing system (10) receives input data from a keyboard (26), a mouse (28) and spoken data input device (30) in an input data sequence. A microphone (32) converts received speech into electrical signals which are digitized by an analogue to digital converter (100). A digital signal processor (102) converts the digital signals into multi-dimensional vectors which are stored in a temporary input buffer (104). A recognition processor (106) performs a recognition program in order to match the multi-dimensional vectors to speech models. In order that the system (10) may output data in an output data sequence which corresponds to the input data sequence, each data input receives a time stamp. A timing controller (24) ensures that instructions received from either the keyboard or the mouse are output only when those instructions have a time stamp which is earlier than the time stamp of the data most recently processed by the recognition processor.

Abstract: A method and apparatus for the selection of random values from a set of N non-sequential values includes software in ROM and RAM for information pool storage. Coupled to the ROM and RAM, a microprocessor sorts the values from smallest to largest, initializes local variables, processes a current value from a first value of the set, and compares the difference to a current information pool entry difference. A range increment is incremented if the difference equals the current information pool entry difference and a new information pool entry is created if the difference does not. The information pool is stored and random values are selected by generating a pseudo random number, constraining the pseudo random number between one and N, indexing into the information pool using the pseudo random number to create a pool entry index and generating the random value using a selected pool entry first value.

Abstract: A computerized system and method for providing event-driven routing to provide user assistance and marketing functions in an order entry system is provided. One or more user-initiated events capable of being recognized by the computer are defined, as are one or more application points. Each of the application points is associated with at least one of the user-initiated events. An action is assigned to each of the application points. The actions assigned to a particular application point are dynamically invoked upon initiation of the user-initiated event associated with that application point, so the user is provided with the action at a point during the placement of an order at which the action is needed.

Abstract: A computerized source searching system and method for the placement of an order for at least one offer via a terminal having a display is disclosed. The system includes system storage for storing offer information, and for storing electronic reproductions of offer sources corresponding to the offer information. The system includes source searching capabilities for locating an offer source, including a display for displaying electronic offer source images, a filtering mechanism for displaying electronic offer source images corresponding to entered source search criteria, and a selection mechanism for selecting one of the electronic offer source images displayed. One or more of the offers associated with the selected electronic offer source image can be located by displaying a segment of the electronic offer source image, and selecting one or more offers in that segment. A user can thereby locate an offer by searching through an electronic equivalent of the offer source used by the person placing the order.

Abstract: A display apparatus simulates a container of gaseous liquid. The display apparatus has a reservoir formed by closely spaced inner and outer walls, at least the outer wall being transparent or translucent and shaped to resemble the container. In use, a foamable liquid is held within the reservoir, and gas is introduced into the liquid at the bottom of the reservoir to thereby form bubbles which rise through the liquid and form a head of foam on the liquid. A foam regulating mechanism allows the gas from burst foam bubbles to escape from the reservoir, but returns the liquid component of burst foam bubbles to the reservoir. The display apparatus is suitable for simulating soda drinks, beer and other aerated beverages.

Abstract: A three dimensional reconstruction of vessel trees from rotational digital subtraction angiogram sequences is described. The goal of the process is to estimate the probability that each voxel contains a vessel using the projection data. The system utilizes x-ray angiographic equipment capable of producing rotational digital subtraction angiogram sequences. Reconstruction of the geometry of the vasculature is based on the projection images. The reconstructed geometry is then displayed on a screen or used for measuring specific physiological parameters. The Dempster-Shafer theory of evidence is used to combine information about location of the vessels from the different projections contained in the digital subtraction angiogram sequence.

A high speed communication clock is coupled to the bus and the receiver for timing the messages transmitted on the high speed communication bus between transmitter and the receiver. A large data buffer is coupled to the high speed communication bus after the receiver for storing messages transmitted between the transmitter and the receiver.
