  • Patent number: 6434419
    Abstract: An efficient, objective testing method and system for evaluating mental acuity and changes in mental acuity is described. The method and system are based on measuring an individual's behavioral responses and brain function during a brief test of working memory and passive control condition. The method and system is designed to assess an individual's overall cognitive ability (“general intelligence”), and whether that overall cognitive ability has been significantly affected by a variety of factors such as progressive disease processes, medication, stress, fatigue or training. The method and system can be used to determine whether drugs being evaluated to treat diseases or conditions affecting higher cognitive brain function have a significant positive effect on delaying or improving the symptoms of such a disease or condition, especially during clinical trials for drug approval and subsequent marketing.

  • Patent number: 6242880
    Abstract: The present invetion involves a tolerance based motion controller. The controller is capable of processing a group of tolerance constraints. The tolerance constraints specify where and when each tolerance constraint is to be applied, along with the information specifying the desired trajectory of motion. There are also a group of velocity constraints, specifying the maximum allowable velocity at each point along the desired trajectory. This information along with sensor feedback is used to modify the velocity along the actual trajectory of motion. This results in the time required traverse the trajectory being as short as possible. Also, the actual trajectory of motion should never exceed the permissible deviation from the desired trajectory, as specified by the tolerance constraints, with the velocity always being bounded by the specified velocity constraint.

  • Patent number: 6195576
    Abstract: A magnetoencephalogram (MEG) method and system for detecting and analyzing the magnetic effects of brain waves uses a dewar having a helmet-shaped cavity and an array of magnetic field detectors arranged in an array. In one embodiment the field detectors are located in the same relative locations as electrodes in the EEG 10/20 system. A subject's MEG data is compared to a normative spontaneous and/or evoked MEG database collected using standardized detector positions and sensory stimuli and/or to a normative QEEG database simultaneously or previously constructed using corresponding standardized electrode positions and sensory stimuli. Statistical parameters in these databases assess the probability that MEG features derived from a subject are within normal limits. Deviations are indicated on interpolated statistical probability maps color-coded to indicate degree of abnormality. Multivariate statistical analyses may be used to categorize brain disorders in individual patients.

  • Patent number: 6104446
    Abstract: A color separation optical plate is described which is superimposed onto a transmissive LCD panel. The color separation plate separates incident white light into its red/green/blue (RGB) components and guides each component through the appropriate sub-pixel (dot) of the LCD panel. The color separation plate utilizes a microprism array of direct vision microprisms each having a combination of refractive and gradient index optics to concentrate the light onto the appropriate dot and to separate the colors. This combination has the theoretical capability of increasing color LCD panel transmissivity by as much as a factor of six.

  • Patent number: 6067467
    Abstract: An electrocephalograph (EEG) method is provided to monitor patients during and after medical operations. An anesthesiologist administers sufficient anesthetics to cause the patient to attain the desired plane of anesthesia. The patient's brain waves, both ongoing and evoked by stimuli, are amplified, digitized and recorded. That pre-operative set of brain wave data is compared to a set of the patient's brain wave data obtained during the operation in order to determine if additional, or less, anesthesia is required, paying particular attention to the relative power in the theta band, as an indication of brain blood flow, and prolongations of the latency periods under brain stem stimuli, as an indication of the patient's ability to feel pain. A set of neurometric features are extracted, converted into a normalized statistical score, a discriminant score is thereby developed and the discriminant score converted to a patient state index using probability functions.

  • Patent number: 6052628
    Abstract: A method and system for routing a digital probe which signals either a triggered or non-triggered state to continuously scan a part surface without having to return to a rest position each time the probe is triggered. The probe is carried by manufacturing equipment capable of moving in response to control signals and providing manufacturing equipment feedback signals indicating the current position of the probe. Continuous movement of the digital probe is achieved by testing the probe to determine if it is triggered or not at a series of closely spaced time intervals, and rotating a move vector (corresponding to desired probe velocity) in each computation cycle to alter the probe trajectory as a function of the operating state of the probe and its position during the previous computation cycle. These techniques allow relatively inexpensive digital probing systems to gather data at speeds comparable to those of much more expensive analog systems.

  • Patent number: 6019554
    Abstract: A computer assisted manual machine tool system and method for milling, turning and grinding uses a computer model of machine objectives and location feedback signals from the tool to control motion switch means enabling and disabling tool motion. The manual machinist may position a tool to a target position by enabling motion along each controlled axis while the tool's position feedback for that axis is outside of the tolerance specification and disabling motion once the tool is within that tolerance. The machinist may contour within a specified tolerance zone by toggling the motion switch means for each axis to produce motion along that contour. The machinist may pocket by enabling motion while the tool is away from the pocket surfaces and disabling motion when the tool position is within a predetermined distance of any pocket surface.
