  • Patent number: 7190995
    Abstract: A system and method for determining respiratory cycle-related EEG changes (RCREC) for a subject with sleep-disordered breathing are provided. The method includes receiving an EEG signal from the subject using at least one sensor, and defining at least two respiratory cycle segments within each respiratory cycle. The method further includes determining an EEG power of the EEG signal during each of the at least two respiratory cycle segments, and determining RCREC by calculating a difference between a maximum EEG segment power and a minimum EEG segment power.
    Type: Grant
    Filed: June 14, 2004
    Date of Patent: March 13, 2007

  • Patent number: 5208685
    Abstract: This invention is a compact optical processor including a coherent light source, plural optical elements that together form a Fourier transform interferometer, and a two dimensional detector array. The light source generates a two dimensional input optical wavefront intensity modulated according to the input signal. The optical elements are formed as slab-like members with parallel input and output surfaces. These optical elements are disposed abutting in tandem. The light detecting device includes a two dimensional array of photosensitive elements generating an image signal corresponding to the processed two dimensional optical wavefront. The plural optical elements preferably include at least one acousto-optical element forming a two dimensional scanner. The plural optical elements may further includes a holographic optical element to block light undiffracted by the scanning elements.

  • Patent number: 5111436
    Abstract: Two dimensional charge coupled device (CCD) memories are coupled to acoustic charge transport devices (ACT) which act as input and/or output multiplexers for the memories. In a preferred embodiment of the invention, the input to a NXM memory is in the form of an optical image projected on the CCD device and the output stage of each column of the memory is provided to one of N FET switches. A 1-D ACT device has multiple taps each connected to the gate of one of the FET switches and as an impulse signal propagates along the ACT channel, the FET switches are successively triggered causing the column outputs to be provided to a summing device to generate a serial output.In an alternative embodiment forming a corner-turn memory, an ACT tapped delay line has a number of equally spaced electrode taps equal to the number of columns of a CCD corner-turn array and each tap is connected to an electrical switch which in turn is connected to an input cell of a bordering row of the array.

  • Patent number: 5040135
    Abstract: The invention is a method for obtaining fringe visibility in hybrid-optical interferometric processors. Encoded data defining an image is utilized to provide both a timing input signal and a method of modulating a light source in synchronization with the modulation of an optical-acoustical element. The modulated light is then detected in a receptor array and converted into signals suitable for driving a readable, visual-imaging device or other devices for image analysis.
