Abstract: CATADIOPTRIC PROJECTOR, CATADIOPTRIC     PROJECTION SYSTEM AND PROCESS                 ABSTRACT OF THE DISCLOSURE         Catadioptric area-of-interest display projectors produce displays having resolution of substantially less than 10 arc minutes per line over a wide field of view.          Such projectors include an external entrance pupil for receiving images of substantially collimated light, and optics for conveying such light onto and through an opening in the surface of an aspheric mirror, and then through an opening in a spherical mirror so that light emerging from the opening in the spherical mirror is displayed on a curved screen surface with such high resolution.         A projector system includes this projector and a mirror for steering collimated light from the entrance pupil of the projector into the projector optics.  This system, when placed in a flight simulator at the periphery of a flight simulator dome for projection of such light images onto the inner curved surface of the dome, provides high resolution images to viewers located at the center of the dome.

Title: Data processing apparatus nulling scalar cache memory
Inventor: KAMIYA YASUAKI
IPC: G06F12/08
Filed: 1990-03-27
Abstract: A data processing apparatus includes an instruction issuing unit, an interval holding unit, a passing control unit, and a nullification processing unit.          The instruction issuing unit tentatively issues a vector store instruction having no definitive data as an instruction not subjected to actual vector store processing.  The interval holding unit obtains and holds a store interval block address to be operated by the vector store instruction tentatively issued from the instruction issuing unit.  The passing control unit compares a block address indicated by a scalar load/store instruction issued from the instruction issuing unit with the store interval block address held by the interval holding unit.  If the block address falls within the range of the store interval block addresses, the passing control unit causes processing for the scalar load/store instruction to wait until the vector store instruction is finally issued from the instruction issuing unit and processed.  When a vector store instruction is tentatively issued from the instruction issuing unit, the nullification processing unit nullifies block data present in a store cache memory of a buffer storing unit of the apparatus and corresponding to a store address of the vector store instruction.

Abstract: RGB components of pairs of adjacent pels of a captured digitized image are averaged.  A perceived color palette is constructed, each color being com-prised of functionally combined RGB components of two different input palette colors.  An array is formed of continuous colors, each indexed to the perceived palette color to which its RGB components are closest and indicating the two input palette colors defining the respective perceived color.  RGB components for each averaged pel pair and the array index are then used to locate the perceived color closest thereto and, the two input palette colors corresponding to the perceived color.  These two input colors are then substituted in a display for those of the two averaged pels and the process repeated for all averaged pel pairs.  In a preferred embodiment, the difference between the perceived and averaged colors is diffused to adjacent averaged pels.  An image is thereby readily produced having substantially more perceived colors than those available in the input palette.

Title: Method and device for separating liquid and a second substance
Inventor: MIDDELBEEK CORNELIS G
IPC: B03D1/24
Filed: 1990-10-04
Abstract: ABSTRACT            METHOD AND DEVICE FOR SEPARATING LIQUID AND A SECOND SUBSTANCE   tHE invention relates to a method for separating at least one liquid, for example water, and a second substance, for instance oil and/or pollutants, from a liquid fluid, for example a suspension or dispersion, by flotation by means of air.     According to the invention, a calm flotation zone, in which small air bubbles are present, is separated by means of a bell-jar periphery from a rise zone for large air bubles. Large air bubbles would disturb the separation because they have a strong tendency to rise, whereby they create agitation more than they carry second substance upwards. The large air bubbles enter the bell-jar. The small air bubbles which adhere to particles of second substance result in an adequate flota-tion of these particles in a calm zone.

Title: Vehicle simulation circuit for inductive-loop traffic signal control systems
Inventor: STRANG CLIFFORD B
IPC: G08G1/042
Filed: 1991-05-17
Abstract: The present invention provides a simulator which when used aboard a vehicle normally undetectable by a traffic signal control system (e.g. A.C. energized buried sensing loop type which detects predetermined changes in the characteristics of an electromagnetic field due to the presence of a detectable vehicle therewithin), will substantially simulate the characteristics of a detectable vehicle within its field and thereby cause any activation of the system. Operationally, the simulator derives an electrical signal from the field (e.g. via a receiving antenna), converts the electrical signal into a modified transmittable signal of an amplitude which when impressed upon the field (e.g. via a transmitting antenna) simulates electromagnetic influence of a detectable vehicle therewithin which is sensed by the detector circuitry and activates an associated traffic signal controller to provide the necessary signals (e.g. a green arrow) to allow safe and unobstructed traffic flow at an intersection.
