Patent CA-2234600-A1 (CA)
Inventor: XIANG QING-SAN
IPC: G01R33/485
Filed: 1998-04-09
Abstract: Chemical shift imaging with spectrum modeling (CSISM) models the general chemical shift spectrum as a system with N distinct peaks with known resonant frequencies and unknown amplitudes. Based on the N peak spectrum model, a set ofnonlinear complex equations is set up that contains N+1 unknowns of two kinds: the magnitudes of the N peaks, and a phasor map caused by main magnetic field inhomogeneity. Using these equations, the timing parameters for shifting the 180° RF refocusing pulses for acquiring spin-echo images are optimally chosen. Corresponding timing parameters for other pulse sequences can also be optimized similarly. Using the chosen timing parameters, a plurality of images are acquired. Next, acquired image data are automatically processed to solve the complex linear equations. First, the phasor map is found by fitting various phasor map values over a small number of pixels, or "seeds", that are picked sparsely in a field of view. Second, from the original "seeds", the region of pixels that are picked to find the best-fit phasor map is grown into the entire field of view, based on a predetermined phase difference between the original seed and a neighboring pixel. The optimal phasor map value is then entered into the complex linear equations to derive the only unknown values at this point -- the peak amplitudes. Optionally, second pass solutions of the peak amplitudes may be obtained using a smoothed phasor map value. When the equations are solved, the spectroscopic images are output.

Inventor: GRANGER EDWARD M
IPC: G06T1/00
Filed: 1997-01-30
Abstract: A target output device such as a printer is characterized in a manner that primary colorant amounts can be determined on the basis of a pair of chromaticity coordinates in a chromaticity space having a pair of chromaticity coordinates that span hue and chroma (saturation) and a luminance coorelate (monotonic function of luminance) (92). Lightness (or darkness) of the colors is handled largely independently. This makes it possible to store the colorant information in a two-dimensional table indexed by chromaticity coordinates (95). Once the colorant values and lightness value for the pixel are determined, the neutral component is determined (97). The information in the table is for colors that are characterized by the highest luminance that the target printer is capable of rendering for a given chromaticity (hue and chroma).

Title: Sensors for detecting changes in temperature, ph, chemical conditions, biological conditions, radiation, electrical field and pressure
Inventor: REIMER ERNEST
IPC: G01K11/12
Filed: 1999-05-28
Abstract: A sensor for detecting changes in a variety of conditions is provided, including temperature, chemical conditions including pH and ion levels, biological antigens, radiation levels, electrical field and pressure applied to the sensor. The sensor body is formed from a material which incorporates an evenly dispersed matrix of light-scattering elements. A light source emits light into the body to form an effective optical cavity in which the light is scattered by the matrix. One or more receivers detects the intensity of scattered or integrated light inside and/or outside of the optical cavity. The matrix and/or the sensor body are composed of materials which reduce or increase the density of light-scattering elements, depending on the conditions applied to the matrix. An increase in the density of the light-scattering elements results in a corresponding increase in the integrated intensity of light received by the receiver, when the receiver is positioned within the optical cavity. At a more distant location, the integrated light intensity at the receiver decreases as the density of scattering elements increases. A processing unit translates the intensity level received by the receiver, into a measure of intensity of the condition detected by the sensor.

IPC: E04C3/02
Filed: 1999-05-27
Abstract: This Invention, called the angle adjuster, is a very useful tool in fabricating frames that are either finger, dovetail or regular joint at any desired angle. framing is commonly done the following way: After the desired frame angle is measured, it has to be stabilized. This is usually done via a strip of wood braced across the corner of the frame, but this technique does not leave any room for further adjustments which often needs to be made during the framing procedure. Having to do the adjustments by repeatedly taking the wood braces off and placing them back on is time consuming and causes frustration, especially when assembling many pieces Improvement of the framing procedure via this invention: This Invention replaces the common wood bracing procedure. The angle adjuster is screwed across the frame angle via its mounting plates, hence stabilizing the desired set frame angle. Any adjustments that need to be made during the framing procedure may be easily done with the adjustment handle of the jig. Turning the adjusting handle will widen or shorten the distance between the mounting screws and thus changing the angle of the frame.  The rest of the frame work has to follow suit. The now stabilized work piece can be handled, glued or clamped etc. until the jig is removed.

IPC: G06F9/455
Filed: 1997-12-24
Abstract: A system and method for providing high speed emulation of a computer system by transforming selected target instructions and bypassing target instruction decoding for those target instructions which have been transformed. A target computer system (12), controlled by a plurality of target instructions (16), is emulated on an emulation host computing system (14). Target instructions (16) are successively loaded into the emulation host computing system (14) in the order that the target instructions would be executed. The target instructions are decoded (24) to identify the functions designated by the target instructions, and these functions are executed (28) by the emulation host computing system (14). Emulation information is assigned to selected target instructions, where the emulation information controls execution of these selected target instructions, referred to as transformed instructions.  Software routines identified by the emulation information are initiated for these transformed instructions, where the software routines execute the functions of the target instruction in the machine language of the emulation host computing system.
