Patent CA-2702017-A1 (CA)
Inventor: WIEGAND THOMAS
IPC: H03M13/03
Filed: 2008-06-20
Abstract: A scalable information signal is protected in a more efficient and/or safe way by adopting the interrelationship among the plurality of portions of different levels within the information signal in FEC protecting the information signal. In particular, portions of the information signal representing the information content at a higher level should have associated therewith redundancy information which is dependent not only on that part of this portion being disjoint to a respective overlapping lower level portion.  Rather, redundancy information should also be dependent on the latter part so as to increase the chances of success of forward error correcting an error within the lower level portion at the reception side.

Abstract: A filament wound composite tube is inserted into a non-metallic mandrel below the core to support the core when holding pressure in the top annulus. The tube has a close-fit tolerance to the inner surface of the mandrel. The tube is secured in place with pins through a mule shoe, such that the bore of the tube is not impeded. Alternately, a retainer with wickers is disposed in the mandrel below the core to support the core when holding pressure in the top annulus. The wickers are biased to engage with an inner surface of the mandrel, holding the insert in place under pressure. Axial movement of the core downward further engages the wickers with the mandrel, helping to support the load.

Abstract: Visceral fat may be removed from a subject using a cannula (30) that has an interior cavity and an orifice (37) configured to permit material to enter the cavity. This is accomplished by generating a negative pressure in the cavity so that a portion of the tissue is drawn into the orifice. Fluid is then delivered in pulses, via a conduit (35), so that the fluid exits the conduit within the cavity and impinges against the portion of the tissue that was drawn into the orifice. The fluid is delivered at a pressure and temperature that causes the visceral fat to soften, liquefy, or gellify, without damaging the subject's internal organs that are in the vicinity of the visceral fat. The visceral fat that has been softened, liquefied, or gellified is then suctioned away.

Title: Method and apparatus for liberating gases from drilling fluid
Inventor: DEGREEVE JASON ALEXANDER
IPC: E21B21/01
Filed: 2010-11-01
Abstract: Described herein are a method and apparatus for analyzing a gas sample that is conveyed in a drilling fluid, and a method and apparatus for liberating gases from drilling fluid. The gas sample contains one or more of methane, ethane, propane, and butane;  optionally, the gas sample may also contain pentane. The gas sample is first liberated from the drilling fluid, following which it is irradiated with infrared radiation in the near-infrared range.  Absorption spectra resulting from absorption of the infrared radiation by the one or more of methane, ethane, propane and butane is simultaneously detected. From the absorption spectra, the composition of the gas sample can be determined. The composition includes a concentration of any one or more of the methane, ethane, propane and butane. Linearity of absorption is increased by using relatively short wavelength infrared radiation centred on, for example, about 1.70 µm, which can increase the accuracy of and reduce the computational intensity of the calculations utilized to determine the composition of the gas sample. Within the near-infrared range, radiation having a wavelength from about 1.55 µm to 1.85 µm can be used. Gases can be liberated from the drilling fluid using a gas trap. The gas trap can be powered using a brushless DC motor, and alternatively or additionally drilling fluid from a sample enclosure of the gas trap can exit via a bubbler enclosure of the gas trap. The brushless DC motor is a relatively efficiency and compact motor that can be used with the gas trap, and is advantageous over convention AC induction and air motor motors. Having drilling fluid exit the sample enclosure through the bubbler enclosure is advantageous in that it helps to make the footprint of the gas trap relatively small.

Abstract: The present invention provides a heatable long range metal target capable of providing acoustic feedback to the user on impact and is durable to withstand the repeated vibration stress that occurs during repeated use. In a preferred embodiment, target includes a reactive target body for generating an audible feedback signal on impact by a firearm round (such as a metal gong), a heating element and a fastening structure connectable to the target body for mounting of the heating element to the target body. The target body has a front, impact surface and a rear surface and is constructed of hardened steel for withstanding repeated impact by high velocity rounds on the impact surface without penetration. The heating element heats a target region of the target and the fastening structure connects the heating element to the target body away from the impact surface. The fastening structure includes a vibration dampening portion for at least partially insulating the heating element from vibrations of the target body generated on impact by the firearm round. Attachment of the heating structure to the reactive target body is made more reliable by using a fastening structure including vibration dampening features, such as an elastic mounting structure.

Abstract: A method is described for overcoming the adverse visual effect of mis-registered ink planes in multiple ink color prints. Color separations are initially made in a normal fashion. The separation carrying the greatest object detail is then chosen as a luminance or achromatic channel. This may be used as is or preferably it is sharpened using a high pass filter. Normally this separation will be black. However, it may be a surrogate color for black, particularly if only two or three separations are made. Object detail in all other separations (chrominance separations) is degraded, usually by a low pass filter such as a Gaussian blur. The printed image formed when the separations are recombined in a conventional manner is remarkably visually tolerant of misregistration of the various ink planes in the image.
