Title: Data slicing system for hdtv receiver
Inventor: HALOZAN SCOTT F
IPC: H04L25/06
Filed: 1993-08-16
Abstract: ABSTRACT OF THE DISCLOSURE     A receiver for receiving transmitted digital signals including either two level or four level symbols that are interleaved in a predetermined pattern in a frame format consisting of a plurality of successive data segments. The symbols are converted into ten bit numbers that are soft sliced to generate four bit numbers representing ranges of values within which each ten bit number may fall. The data represented by the four bit numbers is deinterleaved, a birate flag is generated that identifies that nature of each four bit number, i.e. whether it represents a two level symbol or a four level symbol, and a hard slicer operates, in response to the birate flag, for converting each of the four bit numbers to corresponding two bit binary outputs.

Title: Direct delivery in-situ diffuser cleaning
Inventor: WINKLER WILLIAM W
IPC: C02F3/20
Filed: 1993-11-25
Abstract: This disclosure relates to aeration, especially biological treatment of wastewater with fine pore diffusers and in situ cleaning of these diffusers with liquid and/or gaseous cleaning fluids supplied to the diffusers through cleaning fluid channels that respectively have separate and direct connections to plural diffusers. Aeration and cleaning of fine pore diffusers is described in which cleaning fluid is conducted from a source of such fluid to a multiplicity of diffusers via a flow path which is separate from a flow path which conveys aeration gas to the diffusers. Methods of fabricating aeration gas distribution assemblies are also disclosed. One such method involves securing to an aeration gas distribution conduit at least a portion of a cleaning fluid distribution channel which includes one or more cleaning fluid distribution conduits and further includes connectors coupled to the cleaning fluid distribution conduits. The connectors are spaced longitudinally along the cleaning fluid distribution conduits at the same intervals as, and are connected to, the plenums. Another method comprises fabricating a cleaning fluid conduit having longitudinally spaced tee connectors coupled thereto. An aeration gas conduit having longitudinally spaced plenums secured thereto is fabricated, and such plenums are have holes for receiving the tee connectors coupled to the cleaning fluid conduit. The invention effectively and economically brings cleaning fluid in contact with diffusion elements without lengthy interruptions in wastewater treatment, complicated processing sequences and back-flow of wastewater through the elements, and can be used with diffusers having back-flow prevention capabilities, including membrane diffusers.

Patent CA-2116856-A1 (CA)
Inventor: NELSON LARRY A
IPC: G02F1/136
Filed: 1992-09-17
Abstract: Apparatus and an associated method are described for testing liquid crystal matrix displays that can be performed prior to the assembly of the display. This display procedure involves applying a square wave signal to the control elements and a sine wave signal to the input terminal of an active element associated with the pixel under test. By selection of the sine wave signal frequency, the modulation products resulting from the combination of the square wave signal and the sine wave signal fall between the components resulting from the application of the square wave signal alone.  As a result of the symmetry of the modulation components, a comb filter (304) can be used to select the modulation components. The power of the transmitted modulation products provides a figure of merit for the active element associated with the pixel. A capacitor can be included along with the active element in the matrix display which couples the output signal of each active element to a row (control terminal) electrode (11) on the same substrate as the active element. The capacitor provides an increase in the test result signal to noise level and permits testing of the active matrix substrate prior to display assembly.

Abstract: A gridwork or crib structure is formed from reinforced, injection molded plastic or structural foam plastic crossbeams (11), stringers (13), and fascia members (14), by interlocking the members and pinning the stringers together to form a structure which can function as a gravity retaining wall to retain earth, as a structural wall, or as a water wall. The individual crossbeams include elongated slots (20) and holes (17) into which are connected the stringers, which are then locked and pinned together, thereby forming an initial crib or grid layer at ground level. This crib or grid layers can be built up in height and depth to provide an open structure defining securement channels into which earth (38) is filled. It is relatively easy to build the crib or grid layers to follow uneven perimeters. Openings (33) in fascia elements of the crib or grid enables planting of vegetation into the earth fill for soil retention or decoration.

Title: Volatiles separator and concentrator
Inventor: BOUCHER ARMAND R
IPC: C12H6/02
Filed: 1994-10-04
Abstract: An apparatus and method for stripping volatiles from a feed stream and concentrating the volatiles in the overhead vapors forming a condensate product and simultaneously producing a low percent volatiles outlet stream as a concentrate product.  The volatiles separator and concentrator, ("VSC"), unit has many applications in the reduction and the concentration of volatiles in the beverage, fuel, and industrial alcohol industries, as well as in chemical applications for removing or stripping volatiles from heat sensitive feed substrates which require low temperatures and a short residence time to prevent degradation of the product.      The preferred embodiment of the VSC unit utilizes a short feed stream preheat contact time in combination with turbulent high velocity flow at temperatures below 100°F. to provide flash vaporization for volatiles separation with reboil capability to adjust volatiles concentration in the residue and product.  The application of high vacuum in the range of 27" to 28.5" of Hg further enhances volatiles separation by allowing lower processing temperatures and reduced residence time.  The low pressures and temperatures are energy efficient and serve to minimize heat degradation producing a non-heat sensitized product/residue.  Because of the design of the equipment utilized in the VSC unit, a plurality of VSC modular units can be connected in a series providing a processing system having compact dimensions.

Patent CA-2139941-A1 (CA)
Title: Low power video security monitoring system
Inventor: KOZ MARK C
IPC: H04N5/232
Filed: 1992-07-24
Abstract: If motion occurs in an area viewed by a lens (14) of a video camera (12), a video security monitoring system (10) establishes a communication link with a video monitoring facility and begins transmitting compressed video images of the area. The system (10) is fabricated from CMOS integrated circuits, and operates at a reduced clock frequency while motion is not detected. Reducing the clock frequency lowers the required power thus permitting operation of the system (10) on energy supplied by an ISDN basic access communication channel. If motion occurs, a digital video image compression subsystem (16) begins producing low quality compressed video data for transmission to the monitoring facility. If motion occurs in the central region of the area viewed by the lens (14), then the subsystem (16) produces a single high quality compressed video image. Commands transmitted from the monitoring facility to the video security monitoring system (10) may control its entire operation.
