    摘要: A method and apparatus for controlling the electrical power applied to an electrically driven oxygen separation device having one or more composite membrane elements to separate oxygen from an oxygen containing feed. The composite membrane elements have a resistance increasing during the operation thereof that would act to reduce oxygen output if applied voltage were held constant. In order to increase the time interval for renewing the composite membrane elements, the electrical potential difference is controlled such that the electric current drawn by the elements remains at a substantially constant level by increasing the electrical potential difference as the resistance increases until a predetermined voltage level is reached. Once this level is obtained, the electrical potential difference is maintained at a constant level and the electric current being drawn and the oxygen output is allowed to decay to a predetermined low level after which the element or elements are replaced.

    摘要: Methods are presented that detect and classify mass-like regions exhibiting spiculated and/or dense characteristics with high sensitivity and at acceptable false positive rates. One or more suspicious masses are identified in medical imagery of the breast. In certain embodiments, a quantitative measure of spiculation and quantitative measure of density are computed for each suspicious mass located. At least one classification scheme, developed using true and false positives with similar quantitative measures, is then selected for each suspicious mass according to both quantitative measures. In certain other embodiments, a measure of breast location is computed for each suspicious mass. In one embodiment, the location determines whether a suspicious mass appears inside or outside of the parenchyma region of the breast.

    摘要: A driver for a white LED string or a display is provided. The driver includes a boost converter that is arranged to provide an output voltage from a source voltage. Also, the driver includes a sense resistor that is coupled between the output voltage and a feedback voltage. The sense resistor is coupled in series with the white LED string or the display. Further, the boost converter uses the sense voltage across the sense resistor to regulate the output voltage. In one embodiment, the boost converter includes a level shifter that converts the sense voltage into a comparison signal that is referenced to ground. In another embodiment, the converter employs a reference voltage that is referenced to the output voltage.

    摘要: A method and system that provides users with additional information regarding imagery analyzed by computer-aided detection (CAD) systems is described. A user selects a region of the analyzed imagery. Information is then derived from computational measurements of the region obtained during CAD processing. The region selected by the user does not necessarily have to include a displayed CAD system detection. The information includes a description of the computational measurement and the value of the measurement, both of which are provided in clinically relevant terms.

    摘要: A computer aided detection method and system to assist radiologists in the reading of medical images. The method and system has particular application to the area of mammography including detection of clustered microcalcifications and densities. A microcalcification detector is provided wherein individual detections are rank ordered and classified, and one of the features for classification is derived using a multilayer perceptron. A density detector is provided including an iterative, dynamic region growing module with embedded subsystem for rank ordering and classification of a best subset of candidate masks. A post processing stage is provided where detections are analyzed in the context of a set of images for a patient. Three analysis methods are used to distribute a limited number of detections across the image set and further within each image, and additionally to perform a normalcy classification. The normalcy classification is used to remove all detections from an image set when predetermined normalcy conditions are met. The final output of the system is a set of indications overlaid on the input medical images.

    摘要: A computer system that includes a CPU, a memory and a memory controller for controlling access to the memory. The memory controller generally includes arbitration logic for deciding which memory request among one or more pending requests should win arbitration. When a request wins arbitration, the arbitration logic asserts a “won” signal corresponding to that memory request. The memory controller also includes synchronizing logic to synchronize memory requests, corresponding to a first group of requests, that win arbitration to a clock signal and an arbitration enable signal. The synchronizing logic includes an AND gate and a latch for synchronizing the won signals. The memory controller also asynchronously arbitrates a second group of memory requests by asserting a won signal associated with the second group requests that is not synchronized to the clock signal. In this manner, the won signals for the second group of requests can be asserted earlier than the synchronized won signals, thereby permitting the asynchronously arbitrated second group memory requests to be performed earlier than otherwise possible.

    摘要: A multiple-way cache memory system incorporating circuitry for selectively enabling the sense amplifiers in a given memory bank only when the memory bank contains data that is being accessed. In the disclosed embodiment of the invention, each bank of memory incorporates a bank of at least one sense amplifier that is enabled by a separate sense amplifier control signal. The sense amplifiers in each memory bank are controlled independent of the address decoding logic. Instead, the sense amplifier control signal for each memory bank is generated from tag RAM read hit information and read address data. Preferably, no more than one bank of sense amplifiers is enabled at a time, Power consumption in the cache memory system is thereby greatly reduced.
