  • Patent number: 6697660
    Abstract: An improved method, termed “statistical synthetic aperture magnetometry” (SSAM) of transforming magnetoencephalographic (MEG) measurements into corresponding three-dimensional images of the electrophysiological activity within the brain. The computed images are static, representing the time-integrated brain activity over a selected period. By selecting the time periods and frequency bands of interest, the SSAM method selectively images brain activity relating to different types of brain pathology or to cognitive events. Unlike prior art methods, the SSAM method compensates for the growth of ionic signal source strength estimates with depth into the head, resulting, in part, from the declining sensitivity of the MEG sensors. This is achieved by computing and displaying functions of the ratio of source strength to its noise for each element comprising the image.

  • Patent number: 6675120
    Abstract: A color optical inspection system extracts only such luma and chroma spatial features as are necessary for detection of defects related to the physical characteristics of devices populating the surface of a board. During the training phase, the features of each device present on each of a number of golden boards is extracted and compared against a set of established criteria, thereby to select one or more spatial features to be extracted for the associated devices during the inspection phase. A match region whose boundaries are defined by the selected features of the devices on the golden boards is established during the training phase. During the inspection phase, the selected features of each associated device are extracted to determine whether they fall inside the match region. If the extracted features falls outside the corresponding match region, then a defect is reported.

  • Patent number: 6662169
    Abstract: In a computer system functioning as an autonomous agent with a robotic controller wherein the computer system need not be programmed to perform a specific task, values in an array of error variables are obtained from comparison between an array of resources variables used to indicate resource use and state of an Autonomous Agent and an array of corresponding desired levels for the resource variables. Each individual value in the array of error variables represents an error in the actual value of a particular resource variable as compared to its desired value. Derivative variables for the resource variables and for parameters controlling behavior of the Autonomous Agent are created. The values of the array of error variables and their associated derivative variables are used to adjust values of the behavior-controlling parameters thereby modifying behavior of the Autonomous Agent.

  • Patent number: 6647019
    Abstract: A packet-switch system utilizes a linecard-to-switch (LCS) protocol to integrate linecards with a switch core. Since the linecards include a majority of the buffering of the system and are located physically away from switch core, the size of the switch core can be reduced in size. The LCS protocol is a label-swapping, credit-based, flow-control, which enables the system to operate without requiring such information as the number of port modules available within a switch core or what Qualities of Service (QoS) or multicast flows are available. In addition, the LCS protocol enables the linecards to contain and manage the majority of the buffers in the system, and also to control the data drop policy within the system.

  • Patent number: RE38374
    Abstract: A method of training a recursive filter comprises updating recursive parameters of the filter with delta values computed from sampling of an error signal and obtaining derivative terms of the output signal with respect to the parameters. Adaptation using derivatives for FIR filters is known, but this technique was not available for IIR filters because of the unavailability of the derivative values. However, when it is realized that the derivative itself is recursive, a parameter derivative function is obtained which will produce derivative terms for updating the filter parameters with acceptable filter performance.
