Patent CA-2331831-C (CA)
Inventor: PATEL CHANDRAKANT B
IPC: H04N5/21

Granted: 2003-10-28
Abstract: A DTV signal has a plural-data-segment frame header (figures 3A-3D) includin g complementary first and second ghost-cancellation reference signals (41 and 42) differentially delayed by the duration of two NTSC horizontal scan lines . A receiver for such DTV signal has an adaptive equalizer (11) for baseband symbol code with kernel weights calculated by a computer (26) operative on t he equalizer response after comb filtering. The comb filter (30) combines the equalizer response as differentially delayed by the duration of two NTSC horizontal scan lines to cancel artifacts of co-channel NTSC interference in the comb filtering equalizer response supplied to the computer (26). This reduces the undesirable influence of such artifacts on equalization to reduc e intersymbol interference.

Granted: 2009-05-26
Abstract: An air-pressure head is intended for determining parameters of an air flow, flow of other gases or fluids, as well as parameters of flight of the aircraft. The air-pressure head consists of a multi-edge rod, whose edges are oriented in the rod longitudinal direction, having groups of orifices disposed between the edges on smooth lateral surfaces of the rod which are connected via pneumatic ducts to outlet nipple s disposed off the air flow. Edges in the longitudinal direction are continuous and the ir number is n > 3. Groups of orifices are spaced from the edges at the value of a > 0.1 b , where b is the distance between the edges in any cross-section of the rod. The angle betwee n the lateral surfaces in any cross-section of the rod being y < 180.degree.. S harp edges can be rounded or rendered obtuse by chamfering and also can be implemented in the form of protrusions. The rod lateral surfaces can be convex, cylindrical and tapered . The number of edges on the rod can be 4, 5 or 6. Such parameters of the air- pressure head allow: to improve accuracy of flow (flight) parameters, simplify the design and reduce its weight.

Granted: 2007-04-03
Abstract: Polyethylene glycol) (PEG), a highly biocompatible hydrophilic polyether, is tethered to poly(propylene fumarate) (PPF), a biodegradable polyester. To avoid change in molecular weight distribution of PPF, end hydroxyl groups of PPF are reacted with bis-carboxymethyl PEG after being treated with thionyl chloride. New end carboxyl groups of the PEG-tethered PPF are further reacted with N-hydroxysuccinimide (NHS) in the presence of dicyclohexylcarbodiimide (DCC) to couple bioactive molecules. Glutamine and glycine-arginine-glycine-aspartic acid (GRGD) are attached to the PEG-tethered PPF in 50 mM phosphate buffer of pH of 7.4. The method is valuable for the preparation of a triblock copolymer with PEG end blocks and the coupling of biologically active molecules.

Title: Data transmitting method and receiving method, and video data transmitting device and receiving device
Inventor: OKAMOTO HIROSHIGE
IPC: H04N5/445

Granted: 2011-12-13
Abstract: The present invention is relative to a video signal transmitting/receiving system in which digital video signals are transmitted from a transmitter (30) to a receiver (50) using a line (9) as a transmission channel. The transmitter (30) converts the video signals to be transmitted to a bit string longer in data length than a pixel making up the video signals, allocates a plural number of the bit strings to a blanking period during which pixel data in the pixel string is not transmitted and, using these bit strings, transmits the same superposed data a plural number of times. The receiver (50) extracts the specified bit strings indicating the blanking period from the received data and performs majority processing on the results of demodulation of the extracted bit strings to decide on output data. This reduces errors in reception of supplementary data to simplify the circuit structure as well as to ameliorate the error rate.

Abstract: The machine is adapted to supply, manipulate and position steel strip, fed from a coil, so as to bring it into gapped relationship beneath the side wall of a partly constructed, elevated tank. This is done so that the strip can be welded to the side wall to add a course. It is the objective to ensure that the tank wall is plumb (vertical) and in radius (both as to curvature and relative to the center of the tank) and that the width of the gap is optimized, at the weld point. The machine comprises a 'floating' main frame or platform suspended on a mobile undercarnage by four pivotally mounted cylinders. The cylinders are independently responsive to instruments monitoring the elevation, levelness and plumbness of the tank wall and the width of the gap. The main frame carries the coil and carries the strip and the tank wall in the vicinity of the weld point. The instruments control the cylinders to vary th e elevation, radius and attitude of the main frame to thereby achieve the objective and ensure desirable 'fit up' and gapping at the weld point.

Abstract: A rotary cutterbar includes a gear case containing a series-parallel set of gears including idler gears and pinion gears for driving the cutting discs of the cutter units. The gear case includes top and bottom walls and the idler gears are each received on a hub including an enlarged upper end located in a hole provided in the top wall and a threaded lower end screwed into a hole provided in the bottom wall. The hubs each have a plastic outer shell encasing a metal insert extending axially within the shell, with the shell forming the sole contact between each hub and the gear case whereby vibrations and shock loads respectively due to gear tooth contact and a cutter knife contacting an obstacle are absorbed by the shell to lessen the transmission of noise and the magnitude of the impact force. O-ring grooves are provided in the plastic shell and receive o-rings for preventing leakage from the gear case through the holes in the top and bottom walls. The top end of the metal insert is provided with an internal socket and an external hexagonal surface, with the socket being provided for receiving a complementary shaped wrench which is used for installing the hub by screwing it into the threaded hole and with the exterior surface providing a non-rotational surface to assist in maintaining good physical retention of the insert within the plastic shell.

Title: Self tuning pull-down fuzzy logic temperature control for refrigeration systems
Inventor: MILLER WANDA J
IPC: G05B13/02
Filed: 2002-12-19
Granted: 2005-11-15
Abstract: A pull-down control algorithm for an HVAC refrigeration system (100) is provided. The control algorithm utilizes a fuzzy logic methodology to automatically adjust a flow of refrigerant in the system (100) during a pull - down to maintain a desired pull-down rate. The desired pull-down rate is decreased proportionately as the temperature of the fluid being pulled down approaches a desired operating setpoint to avoid or minimize any overshoot o f the operating setpoint. The desired pull-down rate is obtained by adjusting a rate sensitivity factor used in the control algorithm. When the temperature of the fluid being pulled down is above a predetermined value from the operatin g setpoint, the control algorithm uses a fuzzy logic methodology to determine a rate sensitivity that results in the desired pull-down rate that approaches the operating setpoint without overshoot.
