Abstract: A method and system organize and retrieve information using taxonomies, a document classifier, and an autocontextualizer. Documents (or other knowledge containers) in an organization and retrieval subsystem may be manually or automatically classified into taxonomies. Documents are transformed from clear text into a structured record. Automatically constructed indexes help identify when the structured record is an appropriate response to a query. An automatic term extractor creates a list of terms indicative of the documents' subject matter. A subject matter expert identifies the terms relevant to the taxonomies. A term analysis system assigns the relevant terms to one or more taxonomies, and a suitable algorithm is then used to determine the relatedness between each list of terms and its associated taxonomy. The system then clusters documents for each taxonomy in accordance with the weights ascribed to the terms in the taxonomy's list and a directed acyclic graph (DAG) structure is created.

Abstract: The invention relates to a tissue anchor which is an open helix of biocompatible material having a slope of from 0.5 to 10 turns per centimeter, a length from 3 to 75 millimeters, a diameter of from 1.5 to 11 millimeters, and an aspect ratio of from about 3 to about 5 to 1. The anchor can have a head which is capable of securing or clamping tissue together, such as holding a suture to secure a ligament or tendon to bone. The anchor can also have a head which causes an inward, compressive loading for use in fastening bone to bone, orthopedic plates to bone, or cartilage to bone. The head may be an integral member and may include a self-reinforcing wedge which joins the helix to the head. Further, the elongate member, or filament that forms the helix may have a tapering diameter along its length.

Abstract: This document discusses, among other things, systems and methods for implementing at least partially automated customer relationship management (CRM) distributed across various enterprises or entities. Such entities may include an anchor or affinity enterprise vending a “whole product” to consumers, and various secondary or tenant enterprises vending components of the whole product. Such entities may also include a reseller or other value-adder as the affinity enterprise, and the product manufacturer as the secondary enterprise. By providing a distributed CRM content provider, documentation or other content can be substantially independently created, managed, and/or updated by the particular entity most capable of doing so. Autocontextualization of documents and/or user-provider dialog to concepts allows efficient and inexpensive content management.

Abstract: Optical reproducing apparatus utilizes a dual diffraction grating having first and second diffraction gratings with the diffraction gratings oriented at an angle with respect to one another to polarize an incident return beam into TM and TE components. TM and TE components emerge from the dual diffraction grating at a slight angle with respect to one another and are focused on a photodetector chip by an objective lens. In accordance with a first specific embodiment of the apparatus, the TM and TE polarized components are focused directly on a photoelectric chip, with the TE component focused on a spot size focus detector comprised of three rectangular photoelectric elements. One photoelectric element is disposed between the other two with a pair of parallel interfaces. Disturbances introduced into the TE beam are in the direction of the parallel interfaces, rendering the spot size focus detector wavelength-insensitive.

Abstract: In an optical information storage an retrieval system, the tracking and focus signals have, in the past, been generated by directing radiation beams from each section of a dual half aperture prism to spatially separated dual element sensors and processing the signals from the pair of dual element sensors. In order to reduce cross-talk between the focusing and tracking signals, a radiation beam which has interacted with the optical storage medium is divided into two portions. The first portion of the radiation beam is directed to a dual prism and the radiation beam from each portion of the prism is applied to a different dual sensor. However, the dual half aperture prism divides the radiation beam which has interacted with the storage medium along a plane perpendicular to the projection of the optical storage medium track being monitored. The focusing signal is derived from this pair of dual element sensors.

Abstract: The radiation resulting from interaction with a data track or groove on a storage surface of an optical information storage and retrieval system is separated into three components and detected to provide tracking, focussing, and data signals. The separation is performed using a dual diffraction grating in a single optical path. The division between grating elements in the dual diffraction grating is oriented perpendicular to the data track or groove projected on the grating element. Diffraction radiation components generated by the dual diffraction grating are applied to a first and a second dual sensor elements. The first and second dual sensor elements provide a focusing signal. The undiffracted radiation component transmitted by the dual grating is applied to a third dual sensor. The division between sensors of the third dual senor is perpendicular to the division of the dual grating. Signals from the third dual sensor elements provide the tracking signal and the data signal.

Abstract: In a sensor system for use in the read/write head of an optical information storage and retrieval system, a dual prism separates the resulting radiation beam into two radiation components, the radiation components having a division perpendicular to a projection of a data track or groove on the storage medium projected on the dual prism. Each of the two radiation components is focused by a focus sensor lens on one of two four-quadrant sensors, the four-quadrant sensors forming the system sensor array. The application of the two radiation components generates a tracking signal, a focusing error signal, and a data signal. The orientation of the dual prism results in reduced cross-talk between the tracking signal, which is derived from positive and negative diffraction components, and the focusing signal, which is derived from radiation components having contributions from both the positive and negative diffraction components.

Abstract: A cytofluorometer for simultaneously obtaining multidimensional slit-scan type fluorescence contours of particles, particularly biological cells, in flow. It is recognized that a cell may be effectively partitioned into orthogonal substantially planar cross sections by means of optical imaging through three slit-imaging optical systems, with each of the optical imaging systems viewing the illuminated central region of the cell. Significantly, all optical axes lie substantially in a plane perpendicular to the flow axis. As a result, the depth of focus required is only that necessary to image directly across the flow stream, rather than obliquely as in previous apparatus. This narrower depth of focus can be directly traded fCONTRACT CLAUSESupport for this invention was received through National Cancer Institute Contract No. N01-CB-33862.

Abstract: A triple function image processing system incorporating, for operation in a first COPY mode, a light/lens imaging system for imaging originals at a viewing station or platen to produce latent electrostatic images thereof on a photoconductive surface. The electrostatic images are developed and transferred to a copy substrate material as in conventional xerographic systems. A flying spot light beam is provided in a second WRITE mode, the flying spot beam writing images on the photoconductive surface in response to image signals input thereto. In this mode of operation, the beam impinges on the photoconductive surface at a location upstream of the developing device. And, in a third READ mode, the beam is impinged on the photoconductive surface downstream of the developing device to scan images developed on the photoconductive surface. The scattered light is collected and converted to image signals representative of the image scanned.
