Title: Multipoint digital video communication system
Inventor: CASH GLENN LAWRENCE
IPC: H04N7/26
Filed: 1995-01-23
Granted: 2000-03-07
Abstract: The present invention provides a novel video communication system incorporating multiple window display. According to the present invention, one or more video transmission nodes provide macroblocks of video data available in a plurality of resolution levels. The transmission node encodes the macroblocks and assigns macroblock identifiers (IDs) to each macroblock. A receiving node receives a plurality of video sequences from a plurality of transmission nodes through a communication network. The receiving node operating according to the present invention thereafter eliminates macroblocks of video data that will not be displayed, such as in the case of portions of video that are hidden or overlapped. A macroblock translator also transforms the macroblock ID to a new macroblock ID which reflects the macroblock's position on the display screen as dictated by the user's window configuration. A decoder thereafter decompresses the video data one macroblock at a time, and provides the decompressed macroblock to a frame buffer.      The frame buffer provides the window configured video data to a display.

Patent CA-2151094-C (CA)
Inventor: VOKEY DAVID E
IPC: H04M3/28
Filed: 1995-06-06
Granted: 1999-05-11
Abstract: A novel method and apparatus are used for monitoring cables for wear and damage. The system is particularly applicable to a cable system with multiple branch terminations. The cables have detection conductors, for example the metal cable jackets or other detection conductors extending the length of the conductors. These are connected electrically at the splice points in the system. At the end of each branch and at the end of the main cable, the detection conductors are each connected to a novel termination circuit. In the normal monitoring mode, the termination circuit appears as an open circuit. A DC voltage is normally applied to the detection conductors. Any current is a result of current leakage at a resistive fault along the detection conductors. The termination circuits are activated by altering the DC voltage, e.g. by reversing the polarity and increasing the magnitude of the voltage. This causes the termination circuit to perform a series of functional tests. These include a loop test which places a short across the end of the detection conductor for a timed period. The resulting high level loop current is used to calculate the total detection conductor resistance. A second test transmits a coded signal simulating a triggered splice sensor unit. The signal is detected and decoded to verify proper operation of end to end coded signaling after completing a test cycle, the termination circuit turns off and the next termination to be tested is addressed.

Patent CA-2160095-C (CA)
Title: Internal mix air atomizing spray nozzle
Inventor: HUFFMAN DAVID C
IPC: B05B7/04
Filed: 1995-10-06
Granted: 2007-09-18
Abstract: The nozzle effects three stages of liquid atomization. The first stage is carried out by means of a single liquid orifice and an expansion chamber containing an impingement pin. A high velocity stream of liquid is discharged through the liquid orifice and is broken-up upon striking the flat end of the im-pingement pin. The second stage is produced by an air guide which reduces in area to form jets of air into a high velocity annular air curtain, the curtain passing through the liquid orifice in surrounding relation with the liquid stream and striking the broken-up flow of the first stage to atomize the particles. The mixture is then allowed to expand in the expansion chamber to reduce the tendency of the liquid particles in the atomized mixture from commingling together and reforming into larger particles. The third stage is effected by the expansion chamber and by multiple dis-charge orifices. The mixture is sprayed from the expansion chamber through the multiple orifices and, upon being discharged into the atmosphere, the parti-cles are atomized further due to the release of pres-sure formed inside the expansion chamber.

Filed: 1996-06-25
Granted: 2006-05-30
Abstract: The system is used with a vehicle (V) having an transmitter (E) of e.m. waves and a receiver (R) for the waves returning from a reflector (R') as it passes along the length of a propagation medium (P) of e.m. waves. The Transmitted ( SIGMA e) and reflected ( SIGMA r) waves are compared (C) and a processing module (T) determines the distance between the reflector and the vehicle. The wave emissions and reflections are alternated by sequencers to synchronise the system with a number of positioning devices on vehicles using a transmission network supported by the propagation medium. The sequencers may be placed in the ground and transmit to reflectors the moment when they must be reflecting and to transmitters when they must transmit.

Abstract: There is provided a method of repairing an existing pipe, which comprises introducing at least one leading pig into the existing pipe through one open end thereof, introducing behind the leading pig a necessary amount of adhesive agent into the existing pipe through the same open end thereof, fixing one end of a liner tube at the above open end of the existing pipe, in a manner such that the liner tube may be reversed into the existing pipe, and providing a negative pressure into the existing pipe through an opposite open end thereof to cause the leading pig and the adhesive agent to move forwardly and thus cause the unfixed portions of the liner tube to be reversed into the existing pipe. The adhesive agent is caused to move through the existing pipe in the form of a plug flow, thereby coating the whole internal surface of the existing pipe with the adhesive agent, ensuring that the liner tube reversed into the pipe may adhere to the internal surface of the existing pipe.

Abstract: Compositions for removal of wrinkles in textile fabrics particularly including wool and silk, a primary active ingredient of the compositions being a cationic surfactant or surfactants, preferably based on low molecular weight vegetable oils.  A preferred solvent/carrier is selected to be high purity deionized water which exhibits synergism with the cationic surfactant and with relatively low concentrations of alcohols in the compositions, the anti-wrinkling action of the compositions occurring especially with exceptionally low concentrations of the cationic surfactant or surfactants.          The low concentrations of the cationic surfactants coupled with the low molecular weights of said surfactants reduce residues remaining on the textile fabrics and enable the compositions to demonstrate increased effectiveness on ordinary textile fabrics and extraordinary effectiveness and accept-ability on textile fabrics formed of natural fibers such as wool and silk.  The compositions of the invention can be applied to textile fabrics as a fine mist or by other methods of application and can particularly be used in a home environment without hazard to the fabric or the health and safety of a user.

Abstract: Rodents are entrapped in hot melt adhesive which is disposed on a thermoformed thermoplastic base sheet which has a series of closely spaced ridges defining a rodent runway extending the length of the base sheet. The ridges create a series of depressed valleys which receive the adhesive and engage the quantity of adhesive with the base sheet to mechanically retain the adhesive against shifting off the base sheet. A substantially unobstructed expanse of adhesive without exposed ridges is presented on the runway for encounter by a rodent. Two stiffening ribs extend upwardly from the base sheet on either side of the runway to rigidify the base sheet. Multiple protrusions extend adjacent to each stiffening rib exterior to the runway. The protrusions are engaged on top and bottom by parallel projections of rack members within a paperboard or corrugated container such that multiple glue boards may be stored and dispensed.
