Inventor: BAKER STEPHEN J
IPC: G06T15/00
Filed: 1989-12-04
Abstract: Abstract An apparatus for generating an image to be displayed on a display screen from data defining a model including a plurality of opaque and translucent features. The image is intended to represent a view of the model from a predetermined eyepoint and is made up from an array of screen space pixels to be displayed by a raster scanning process. Each pixel is of uniform colour and intensity, and the pixels together define an image area. The image area is divided into an array of sub-areas each of which covers at least one pixel. For each feature in the model that is potentially visible from the eyepoint, a test is conducted to determine which of the sub-areas is at least partially covered by that feature. A list of feature identifiers is produced in respect of each sub-area, the list for any one sub-area identifying features which at least partially cover that sub-area. The position in screen space of at least one sampling point within each sub-area is determined. For each sub-area in turn, and for each sampling point a test is conducted to determine which of the features in that sub-area's list cover that sampling point. For each feature which covers a sampling point, a function of the distance from the eyepoint to that feature at the sampling point is determined. Feature describing data is stored for each sampling point within a sub-area, the stored data being indicative of at least the distance of the opaque feature which covers the sampling point and is nearest to the eyepoint and the distance and translucency of at least one nearer translucent feature which covers the sampling point. An output is produced for each sampling point within a sub-area, the sampling point output corresponding to the combined effects of the features identified by the stored data. An output for each pixel within a sub-area is produced, the pixel output corresponding to the combined effects of the sampling point outputs for all sampling points which contribute to that pixel, and the pixel outputs are displayed.

Title: Control system for an industrial dryer
Inventor: NORZ GERALD R
IPC: F26B21/00
Filed: 1990-08-10
Abstract: CONTROL SYSTEM FOR AN INDUSTRIAL DRYER       ABSTRACT OF THE DISCLOSURE     A control system for an industrial dryer used to remove a flammable solvent or vapors from a traveling web of material or the dryer.  The dryer consists of a chamber which is preferably a large metallic cylinder through which the web of material moves longitudinally.          Seals in the metallic cylinder at the points of entry and exit of the traveling web permit the control system to maintain the desired environment under controlled pressure within the metallic cylinder.   The web of material travels successively through one or more zones within the metallic cylinder.  At each zone, the web of material is exposed to a pressurized atmosphere which may  be  at  increasingly  higher  temperatures.    The solvent is recovered from the pressurized atmosphere by rapid  cooling, membrane  separation  or  absorption.          Sensors within each zone measure the oxygen content of the pressurized  atmosphere.    If  the  oxygen  content exceeds  a  given  threshold,  pressurized  nitrogen  or other inert gas is added.  Through the use of a carbon bed at the last zone, the pressurized atmosphere from that zone is rendered sufficiently free of solvent to be exhausted to the air or a nitrogen recovery unit, thereby maintaining the desired overall pressure within the metallic cylinder.

Title: Malicious call detection method and system
Inventor: SHINMOTO TETSUO
IPC: H04M3/533
Filed: 1990-10-22
Abstract: ABSTRACT OF THE DISCLOSURE        In a telephone switching system, subscriber line interfaces are connected to a switching network for detecting a hook flash. A three-way trunk circuit operable in a called-party release mode is connected to the network in addition to incoming and outgoing trunks. Individual subscriber data are stored in a main memory indicating the presence or absence of a request from a subscriber for detection of a malicious call and a telephone number of a third-party subscriber. The control unit of the system is responsive to a normal call request for establishing a normal connection in the switching network and clearing it on a calling party or first-party release basis, and responsive to the detection of a hook flash by a subscriber line interface for identifying it as corresponding to the subscriber from which the request is made. A first connection is then established between the identified subscriber line interface and the three-way trunk, and the normal connection between the identified subscriber line interface and a calling party from which the malicious call has originated is cleared. A second connection is established between the three-way trunk and the malicious calling party and a third connection between the three-way trunk and a subscriber line interface of the third-party subscriber.
