Title: Method and apparatus of protecting explosives
Inventor: JONES CLAUDE D
IPC: E21B43/116
Filed: 2001-06-13
Abstract: A method and apparatus to protect explosive components (704 or 804) used in various tools, such as tools for use in wellbores, includes a component (704 or 804) with an adsorptive material (702 or 802). Example tools include perforating gun strings (110) that include shaped charges (700 or 800), detonating cords (220), and booster explosives (114). Other tools may include surface tools containing explosive components. In these tools, a build up of corrosive gases or liquids may occur, which may cause damage to the explosive components (704 or 804). As a result, the structural integrity or reliability and thermal stability may be weakened or reduced. To reduce the amount of build up of corrosive gases or liquids, an adsorptive material (702 or 802) is placed inside tools in the proximity of explosive components (704 or 804).

Abstract: A new start-up operation of a continuous caster is monitored by comparing itself with the normal start-up operation, which is benchmarked by a multivariate statistical model using selected historical operation data. If the new operation is statistically different from the benchmark, then alarms are generated to indicate an impending start cast breakout and at the same time, the process variables that lead to process excursions from the normal operation are identified as the most likely root causes of the predicted breakout. The model is built using Mult-way Principal Component Analysis technology to characterize the operation-to-operation variance in a reduced dimensional space (also known as latent variable space) based on a large number of process trajectories from past normal start-up operations.     The process trajectories over the entire start cast duration are predicted based on the current observations. They are then synchronized by interpolating themselves based on pre-specified non-uniform synchronization scales in the strand length such that all trajectories can be aligned with respect to the strand length for further use in model development.

Title: Cannulated screw and associated driver system
Inventor: POANDL THOMAS M
IPC: A61B17/00
Filed: 2002-12-20
Abstract: A driver for inserting cannulated screws has a tool portion, e.g., in the form of a hex wrench that slips into the cannula of the screw. A tapered threaded tip on the tool extends beyond the front tip of the screw. An abutment surface provided, e.g., by the tool holder acts as a limit to rearward motion of the screw when it is being screwed into a substrate such as bone. The threaded tip of the tool cuts the bone to allow the threads of the cannulated screw to follow into the substrate permitting use of a softer material, such as a bioabsorbable material for the screw.

Title: Method of determining the relative position of a first and second imagesetting device with respect to each other
Inventor: ZINTZEN BERNHARD
IPC: H04N1/191
Filed: 2003-01-06
Abstract: A method is presented of determining the relative position (510) of a first imagesetting device (56) with respect to a second imagesetting device by setting images (58) on an associated imagesetting medium (54), said method comprising at least the following steps: an image of a group of mutually different reference patterns (16) and a basic pattern (18) is set by means of the second imagesetting device (58), which serves as a master, each reference pattern (16) from the group being assigned uniquely to one relative position. An image of at least one test pattern is set by means of the first imagesetting device (56), whose relative position is to be determined, over the basic pattern, so that a combination pattern (24) is produced. A reference pattern (16) whose area coverage coincides with the area coverage of the combination pattern (24) is determined. Since a relative position (510) is associated in a unique way with the identified pattern from the group, the relative position of the first with respect to the second imagesetting device (56, 58) is identified. The method according to the invention can advantageously be used in a printing form exposer or in a printing unit (52) of a printing press (50).

Title: Design of communications networks
Inventor: SHIPMAN ROBERT ANDREW
IPC: H04L12/24
Filed: 2001-09-14
Abstract: An apparatus and method are provided for designing at least a part of a communications network beginning with an initial network design, a set of traffic handling requirements and an initial set of design rules. Each rule includes a condition portion and an action portion and at least one such rule includes a portion expressed in terms of at least one variable parameter. An iterative procedure is implemented to evolve both a network design and a set of design rules comprising variations to rules from the initial rule set. A  population of rule sets is generated with each rule set using a different combination of assigned parameter values. For each rule set in the population of rule sets, rules for which the condition portion is satisfied are applied to generate a modified network design. Measures of performance, including cost of each modified design are determined through simulation of the operation of the design on the basis of the traffic handling requirements and the performance and cost of different designs compared. A preferred design then forms the basis for further modified network designs and the particular rule set that generated the preferred design forms the basis of a new rule set population in the next iteration.

IPC: G06F17/00
Filed: 1992-10-23
Abstract: Disclosed is a system and method to obtain 19 unipolar EEG signals from regions of interest on both the left and right hemispheres of a subject's brain. The system uses high-gain, low-noise amplifiers to maximize the dynamic range for low energy wave components of the signals. Band-pass filtering is used to reduce noise and to avoid aliasing. The system applies commonly used digital signal processing (DSP) techniques to digitize, to low-pass filter (50 Hz), and to decimate the signals.      Power spectral, bispectral, and higher-order spectral processing is then performed. In a preferred embodiment, the system divides the most recent 63 seconds of digitized EEG data from each lead into 60 4-second intervals, each with 3 seconds of overlap with the previous interval. For a selected set of derived leads, the system produces auto power spectrum, autobispectrum, and auto higher-order spectrum variables, by using either a Fourier Transform based approach or a parametric cubic fitting approach. Any pair of leads can be combined to compute cross power spectrum, cross bispectrum, and cross higher-order spectrum variables.
