  • Patent number: 7601123
    Abstract: The apparatus and methods of the present invention provide a non-invasive measurement of blood pressure with a frequency that approximates a continuous measurement. Blood pressure measurement provides information that is both clinically and diagnostically significant. In accordance with an aspect of the present invention, a method for providing a non-invasive measurement of blood pressure, includes obtaining a first input signal and a second input signal indicative of systolic blood pressure and diastolic blood pressure, respectively; tracking a signal indicative of pulse pressure; continuously measuring a third signal indicative of mean blood pressure; and processing the signals to obtain a measurement indicative of systolic and diastolic blood pressure, wherein at least a portion of the measurement indicative of systolic and diastolic blood pressure is continuous.

  • Patent number: 7549116
    Abstract: A computer program product comprising a computer useable medium includes a computer readable program, wherein the computer readable program when executed on a computer causes the computer to display a data set as a table including a plurality of cells. Additionally, the computer readable program when executed on a computer causes the computer to assign a column width to each cell in a row of the table, independently of other table rows having differing layouts, such that the table is capable of displaying a plurality of different row layouts simultaneously. The computer readable program when executed on a computer causes the computer to display a dynamic header configured to display a row layout of a selected row of the table. Further, the computer readable program when executed on a computer causes the computer to increase a readability of the dynamic header with respect to the selected row by various mechanisms.

  • Publication number: 20050179702
    Abstract: A real time embedded video processing system includes a central processing unit (CPU); a real time operating system; and an input/output interface that receives user input via a user input device. The system runs a graphics application that generates computer graphics in response to user input. A device control application controls multiple different video input sources in response to user input. The system includes a video processing engine comprising a dedicated logic circuit, such as a field programmable gate array (FPGA). The circuit includes a pixel processing engine that receives input from at least one of the video input sources and receives computer graphics from the graphics application. The pixel processing engine alpha blends the computer graphics with the video input and then outputs the blended data in real time.

Blood pressure measurement provides information that is both clinically and diagnostically significant. In accordance with an aspect of the present invention, a method for providing a non-invasive measurement of blood pressure, includes obtaining a first input signal and a second input signal indicative of occlusive measurements of systolic blood pressure and diastolic blood pressure, respectively; tracking a signal indicative of pulse pressure; continuously measuring a third signal indicative of mean blood pressure; and processing the signals to obtain a measurement indicative of systolic and diastolic blood pressure, wherein at least a portion of the measurement indicative of systolic and diastolic blood pressure is continuous.
