Title: On-line training neural network for process control
Inventor: SKEIRIK RICHARD D
IPC: G05B13/02
Filed: 1991-07-25
Granted: 2003-04-22
Abstract: An on-line training neural network for pro-cess control system and method trains by retrieving training sets from the stream of process data. The neural network detects the availability of new train-ing data, and constructs a training set by retrieving the corresponding input data. The neural network is trained using the training set. Over time, many training sets are presented to the neural network.     When multiple presentations are needed to effec-tively train, a buffer of training sets is filled and up-date as new training data becomes available. The size of the buffer is selected in accordance with the training needs of the neural network. Once the buf-fer is full, a new training set bumps the oldest train-ing set off the top of the buffer stack. The training sets in the buffer stack can be presented one or more times each time a new training set is con-structed. A historical database of timestamped data can be used to construct training sets when training input data has a time delay from sample time to availability for the neural network. The timestamps of the training input data are used to select the ap-propriate timestamp at which input data is re-trieved for use in the training set. Using the histori-cal database, the neural network can be trained ret-rospectively by searching the historical database and constructing training sets based on past data.

Title: Eigenfrequency phase shift control loop for fiber optic gyros
Inventor: WINSTON CHARLES R JR
IPC: G01C19/72
Filed: 1991-05-24
Granted: 1998-11-03
Abstract: A fiber optic rotation sensor having a pair of light beams counterpropagating in a loop includes a phase modulator for modulating the waves at a first frequency, upon exiting the loop the waves are combined into a light intensity signal indicative of rotation rate and is sensed. A signal at the first frequency is quadrature phase shifted by a lower frequency signal and summed with the sensed rate signal, an amplifier amplifies the summed signals, the amplifier also inherently induces undesirable phase shifts by an equal amount in both the sensed rate signal and the quadrature signal. The quadrature signal is demodulated and used in feedback fashion to control the phase of a variable phase shifter which provides a signal at the first frequency whose phase is shifted by an amount equal to the undesirable phase shift of the sensed rate signal, the variable phase shifter signal and the sensed rate signal being provided to a demodulator to demodulate rotation rate information from the sensed rate signal.

Abstract: A rigid three-dimensional preform is made by moving a plurality of webs of fibrous reinforcement material superposed and coplanar to a cutter, the webs being coated with an electromagnetic energy-curable binder and pressed together. Prior to cutting a blank in a two-dimensional development of the three-dimensional preform from the webs, the webs are tacked together at spaced local zones by locally curing the binder at those zones by locally applying the appropriate electromagnetic radiation (microwave, ultraviolet, electron) so that the webs travel as one to the cutter. After cutting of the blank, the blank is loaded into a mold to replicate the three-dimensional shape of the preform and the remainder of the binder is cured in the mold by the application of the appropriate electromagnetic radiation. An auxiliary member may be attached to the preform by applying an electromagnetic energy-curable binder to at least one location on the preform, moving the auxiliary member into a desired position and intimate contact with the binder-coated location and the binder cured at that location by the application of the appropriate electromagnetic radiation.

Inventor: SAYEED KABEER AHMED
IPC: G11C13/06
Filed: 1993-03-05
Granted: 2002-05-14
Abstract: Devices for optical storage of information consist of an optical storage medium and an optical device, generally known as a head to read information from or write information onto the medium. In order to read from or write information onto the various points on the surface of the medium there usually is relative motion between the head and the surface of the storage medium. This is usually accomplished by moving the head, the surface or both in such a manner as to bring the desired points of the surface to the immediate neighbourhood of the head so that the head may read information from or write information to these points. It is most common to have the storage medium in the form of a circular platter which spins while the head traverses the surface of the disc following a path which is approximately radial relative to the platter.      In this invention, the need for relative motion between the optical storage medium and the head is eliminated by the use of a two dimensional array of optical elements which cover the surface of the corresponding two dimensional optical storage medium. Each element consists of optical reading and writing devices which are used to read information from or write information onto a location on the surface of the optical storage medium which is directly opposite to the optical element. The optical elements may be packed together as closely as is permitted by the currently available technology and the shape of this two dimensional array of optical elements and the two dimensional optical storage medium may be made to correspond to each other so as to maximise the amount of information stored on the surface of the optical storage medium.   The array of optical elements can be controlled so as to concurrently write to or read from multiple locations on the storage medium or to write to or read from only one point at any given instant of time.   Furthermore, by using two arrays of optical elements, one on each side of a two dimensional optical storage medium capable of storing information on both sides, information may be written to or read from both surfaces of the storage medium.

Title: In-situ treatment system for inhibiting the formation of, and for alleviating, acidity in water
Inventor: CHESWORTH WARD
IPC: C02F1/461
Filed: 1993-06-16
Granted: 2001-07-31
Abstract: Treatment is described for acidity caused by water seeping down through a seam of acid-generating mineral such as pyrite. The pyrite oxidises through exposure to the atmosphere (as a result of mine workings). The treatment system creates an electrolytic cell, using the submerged portion of the pyrite seam as the cathode, the water in the aquifer as the electrolyte, and a body of scrap iron immersed in the water as the (sacrificial) anode. Contact rods are inserted into the pyrite seam, and are connected, via a cable, to the body of scrap iron, which is placed in a nearby pond. Hydrogen ions migrating to the cathode bubble off as hydrogen gas, thereby raising the pH. The acid generating reactions in the pyrite seam are inhibited, and acid concentrations in the already contaminated water in the pond and in the aquifer are reduced. In an alternative, the exposed beaches of pyrite in a tailings pond are provided with grids of metal mesh in place of the inserted rods.      The grids provide a better contact with the pyrite.

Granted: 1998-12-01
Abstract: A mass spectrometry method in which notch-filtered noise is applied to an ion tr ap to resonate all ions except selected parent ions out of the region of the trapping field (16). Preferably, the trapping fiel d is a quadrupole trapping field defined by a ring electrode (11) and a pair of end electrodes (12,13) positioned symmetrically alo ng a z-axis, and the filtered noise is applied to the ring electrode (11)(rather than to the end electrodes) to eject unwanted ions in radial directions (toward the ring electrode) rather than toward a detector (24) mounted along the z-axis. Application of the filtere d noise to the trap in this manner can significantly increase the operating lifetime of such an ion detector.
