摘要： Systems and methods are disclosed for determining physiological information in a subject. The system includes; a light source positionable along a first location outside of the subject; a photo-sensitive detector positionable along a second location outside of the subject and configured to detect scattered light and generate a signal; a processor having a program and a memory, wherein the processor is operably coupled to the detector and configured to receive and store the signals generated over a period of time; wherein the processor is programmed to derive contrast metrics from the stored signals, calculate a waveform from the contrast metrics, decompose the waveform into basis functions and respective amplitudes, and compare the basis function amplitudes to determine the physiological information.

摘要： A method and system for programming and reading a magnetic memory is disclosed. The magnetic memory includes a plurality of selectable word line segments and a plurality of magnetic storage cells corresponding to each word line segment. The method and system include reading the magnetic storage cells corresponding to a word line segment to determine a state of each magnetic storage cell. The method and system also include writing data to a portion of the magnetic cells corresponding to the word line segment after the reading. The method and system also include rewriting the state to each of a remaining portion of the magnetic storage cells corresponding to the word line segments at substantially the same time as the portion of the magnetic cells are written.

摘要： Methods and apparatus for measuring perfusion using transmission laser speckle imaging are provided. The apparatus comprises a coherent light source and a detector configured to measure transmitted light associated with an unfocused image at one or more locations. The coherent light source and detector are positioned in a transmission geometry. The apparatus further comprises means for securing the coherent light source and the detector to the tissue sample in a fixed transmission geometry relative to the tissue sample. The apparatus may further comprise at least one processor to receive information from the detector and process detected variations in transmitted light intensity to determine a single metric of perfusion. The method may comprise the steps transilluminating a tissue sample with coherent light, recording spatial and/or temporal variations in the transmitted light signal, determining speckle contrast value(s), and computing a metric of perfusion.

摘要： A method and system for providing a magnetic memory including magnetic memory cells associated with a word line segment is disclosed. The magnetic memory cell includes a magnetic storage device and an isolation device. The isolation device is coupled to the magnetic tunneling junction and with a combined word line for reading and writing to the magnetic memory cell. The magnetic storage device and the isolation device are configured such that no direct current path to ground exists during the writing to the magnetic memory cell. In one aspect, in a write mode, the combined word line associated with the word line segment and the word line segment are activated. In the read mode, at least a portion of the memory cells associated with the word line segment are selected using the combined word line.
