摘要:
A sensor device that detects Laplacian electroencephalogram (LEEG) signals includes a signal acquisition module placed on a scalp of a subject to acquire brain signals. A signal processor is coupled or connected to the signal acquisition module to perform a Laplacian operation on the signals acquired by the signal acquisition module such that the noise signal is reduced to yield an analog LEEG signal with a high signal-to-noise (S/N) ratio.

A single bridge magnetic field sensor includes a fluxguide mounted to a surface of a substrate. A bridge unit includes first, second, third, and fourth magnetoresistive elements mounted around the fluxguide and mounted on the surface of the substrate. A switching circuit is electrically connected to two voltage inputs, two grounding terminals, two voltage output terminals, and the four magnetoresistive elements. The switching circuit can proceed with circuit switching according to a magnetic field in each axis direction to be measured, thereby changing electrical connection between the voltage inputs, the grounding terminals, the voltage output terminals, and the four magnetoresistive elements. A measuring unit is electrically connected to the two voltage output terminals and the four magnetoresistive elements. The magnetoresistances of the four magnetoresistive elements measured by the measuring unit and output voltages of the voltage output terminals can be used to obtain a magnetic field measurement result.

摘要:
A method of reducing oxide thickness variations in a STI pattern that includes both a dense trench array and a wide trench is described. A first HDP CVD step with a deposition/sputter (D/S) ratio of 9.5 is used to deposit a dielectric layer with a thickness that is 120 to 130% of the shallow trench depth. An etch back is performed in the same CVD chamber with NF3, SiF4 or NF3 and SiF4 to remove about 40 to 50% of the initial dielectric layer. A second HDP CVD step with a D/S ratio of 16 deposits an additional thickness of dielectric layer to a level that is slightly higher than after the first deposition. The etch back and second deposition form a smoother dielectric layer surface which enables a subsequent planarization step to provide filled STI features with a minimal amount of dishing in wide trenches.

The method of presenting concurrent information about the electrical and mechanical activity of the heart using non-invasively obtained electrical and mechanical cardiac activity data from the chest or thorax of a patient comprises the steps of: placing at least three active Laplacian ECG sensors at locations on the chest or thorax of the patient; where each sensor has at least one outer ring element and an inner solid circle element, placing at least one ultrasonic sensor on the thorax where there is no underlying bone structure, only tissue, and utilizing available ultrasound technology to produce two or three-dimensional displays of the moving surface of the heart and making direct measurements of the exact sites of the sensors on the chest surface to determine the position and distance from the center of each sensor to the heart along a line orthogonal to the plane of the sensor and create a virtual heart surface; updating the measurements at a rate to show the movement of the heart's surface; monitoring at each ultrasonic sensor site and each Laplacian ECG sensor site the position and movement of the heart and the passage of depolarization wave-fronts in the vicinity; treating those depolarization wave-fronts as moving dipoles at those sites to create images of their movement on the image of the beating heart's surface; and, displaying the heart's electrical activity on the dynamically changing image of the heart's surface with the goal to display an approximation of the activation sequence on the beating virtual surface of the heart
