Filed: 1993-04-05
Abstract: A hermetically sealed optical fiber cable (20) includes a core (21) comprising a plurality of optical fiber ribbons (22,22) disposed within a core tube (30) comprised of a high temperature resistant polymeric material. The core tube is disposed within a hermetic sealing member (40) which comprises a metal of low electrochemical activity having a sealed seam. An outer jacket (50) is disposed about the hermetic scaling member. The core may be filled with a waterblocking filling material (35). The material of the core tube undergoes only limited degradation because of the limited amount of oxygen and/or moisture trapped in the hermetically sealed cable. The filling material and/or other materials of the cable scavenge moisture and oxygen which travel longitudinally of the cable and reach portions of the cable subjected to a high temperature because of a leak in an adjacent steam line. The filling material and/or other materials are such that they cooperate with polymeric materials of the cable to prevent oxygen and humidity from degrading coating material of the optical fiber. Further, the filling material and the core tube are such that degradation of the core tube in the hermetically sealed cable is avoided.

Inventor: BUCHOLZ RICHARD D
IPC: A61B19/00
Filed: 1991-10-17
Abstract: The system for determining a position of a probe relative to an object such as a head of a body patient. The head includes a surface such as a forehead having a contour. The head is placed in a cradle equipped with an arc. The cross-sectional images of the head are determined relative to the arc. A hand-held unit optically scans the forehead and the arc. During scanning to generate the cross-sectional images, the optical scanner is used to determine the position of the forehead relative to the cradle. During surgery, the optical scanner also determines the position of the forehead relative to a base ring. An array for receiving radiation emitted from the probe and from the base ring generates signals indicating the position of the tip of the probe relative to the base ring. A stereotactic imaging system selects and display the image of the head closest to the measured position of the tip of the probe.

Title: Revolutionary gear system 2000
Inventor: KADDOURA ALI N
IPC: F16H3/42
Filed: 1993-11-25
Abstract: A gear system is used for changing the speed of a vehicle. A gear system provides a number of optional ratios of  (output R.P.M)/(input R.P.M) by connecting between two gears for every option. A new system is to be designed so the R.P.M ratio can vary linearly without the need of using large number of gears, and without the need of an automatic or manual transmission. Such a gear system will make driving more convenient by eliminating the need for manual transmission in a stickshift car, or by eliminating the jolting which results from using automatic shifting. It will also improve the fuel efficiency of the vehicle by providing the most efficient combinations of R.P.M and R.B.M ratio for the desired speed.

Abstract: A two-pass classification system and method that post-processes HMM scores with additional confidence scores to derive a value that may be applied to a threshold on which a keyword verses non-keyword determination may be based. The first stage comprises Generalized Probabilistic Descent (GPD) analysis which uses feature vectors of the spoken words and the HMM segmentation information (developed by the HMM detector during processing) as inputs to develop a first set of confidence scores through a linear combination (a weighted sum) of the feature vectors of the speech. The second stage comprises a linear discrimination method that combines the HMM scores and the confidence scores from the GPD stage with a weighted sum to derive a second confidence score. The output of the second stage may then be compared to a predetermined threshold to determine whether the spoken word or words include a keyword. <IMAGE>

Abstract: Disclosed is an ophthalmic lens inspection method and apparatus comprising a camera to capture an image of an ophthalmic lens which has been illuminated by a light source. location and intensity at each camera pixel is converted to an electrical quantity which is then transferred and stored in a memory. A computer containing instructions for comparing the intensity and location values of the pixels starts near the center of the receptor field and continues toward the edge of the field until an intensity deviation is encountered. By evaluating the pixels containing intensity variation, an outline of the lens edge is attained. An annulus is generated enclosing the actual lens edge. All the pixels are changed from an absolute intensity value to a gradient value, represented by two transition edges. Feature extraction is performed to locate defective pixels and place them into groups. Once the groups have been determined each is given a score based on the number, type and severity of the defective pixels placed into that group. From that, a weighted score can be given to the entire lens and the lens either passes or fails.
