Inventor: BISHOP ARTHUR E
IPC: B62D5/083
Filed: 1992-04-30
Abstract: A hydraulic power steering rotary valve of generally conventional construction characterized in that the on-centre charac-teristics of the valve are governed by an arrangement of rolling elements (22) and notched elements (10, 20) arranged to produce a detent action between the input shaft (1) and the sleeve or driven member (2), the rolling elements (22) rolling between opposite surface contours of a pair of opposed notched elements (10, 20), the contours each including a convex surface the shape of which is such that a centering torque between the input shaft (1) and the sleeve or driven member (2) is produced which decreases for increasing amounts of rotation away from a neutral condition of the rotary valve.

Title: Variable rate vocoder
Inventor: JACOBS PAUL E
IPC: G10L25/93
Filed: 1992-06-03
Abstract: An apparatus and method for performing speech signal compression, by variable rate coding of frames of digitized speech samples (10). The level of speech activity for each frame of digitized speech samples is determined and an output data packet rate is selected from a set of rates based upon the determined level of frame speech activity. A lowest rate of the set of rates corresponds to a detected minimum level of speech activity, such as background noise or pauses in speech, while a highest rate corresponds to a detected maximum level of speech activity, such as active vocalization. Each frame is then coded according to a predetermined coding format for the selected rate wherein each rate has a corresponding number of bits representative of the coded frame. A data packet is provided for each coded frame with each output data packet of a bit rate corresponding to the selected rate.

Title: Method and Device for Ventilating Pocket Spaces in a Multi-Cylinder Dryer of a Paper Machine
Inventor: VIRTA RAIMO
IPC: F26B13/10
Filed: 1994-03-30
Abstract: A method and apparatus for ventilating pocket spaces in a multi-cylinder dryer of a paper machine, in particular a high-speed paper machine whose running speed is higher than about 800 meters per minute, in the area of a so-called twin-wire draw.   In the twin-wire draw,  the drying cylinders in the drying group are arranged in two rows placed one above the other, in which rows the successive cylinders are placed in the upper row and in the lower row as interlocked.  In each cylinder group, there are two drying wires, an upper wire and a lower wire for pressing the paper web against heated faces of the drying cylinder while being guided by guide rolls placed in gaps between the cylinders.  The paper web runs as free draws between the rows of cylinders.  Pocket spaces are formed in the area between the free draws of the web and the upper wire and its guide roll and the drying cylinder in the lower row and, in a corresponding manner, adjacent pocket spaces are formed in the area between the free draws of the web, the lower wire, its guide roll, and the drying cylinder in the upper row. The pocket spaces are ventilated by pumping air induced by the wire in the multi-cylinder dryer, wherein, at the inlet side of the guide roll, the wire pumps air into the pocket spaces through the wire and wherein the wire pumps air out of the pocket spaces at the outlet side of the guide roll of the wire.  Air being pumped out through the wire on its run at the outlet side from the guide roll to the following cylinder is limited as compared with free pumping-in and pumping-out so as to control the pressure level and/or the flow status in the pocket spaces.

Title: Vehicular traffic monitoring system
Inventor: MATHUR BIMAL P
IPC: G06T1/00
Filed: 1994-11-18
Abstract: A vehicular traffic monitoring system incorporates an array of photosensors and a nonlinear resistive network for identifying, locating, and processing outliers in sensor images of a highway or intersection. The camera system can be mounted on a pole or overpass to provide an image of the roadway or intersection. Areas of the outlier network ("video loops") are designated to correspond to selected areas of the roadway. Images are received by the outlier detection network with all data path switches closed between sensor elements and their corresponding network nodes. The system detects the presence of objects in the image by comparing the brightness or intensity of each pixel with that of the background. If the intensity of a pixel is significantly different from the background level, the data path switch corresponding to that pixel is opened. A readout of the state of all the switches in the network yields a map of outlier points for each video frame. The outlier map is connected to a data processing system to identify and locate outlier points in the image. The detection of a threshold number of outliers in a video loop indicates the presence of a vehicle at the corresponding area of the roadway. The processor, having a greatly reduced computational load without extensive image processing, simply measures and transmits traffic data such as the number and speed of vehicles passing through the video loops.
