Patent CA-2218668-A1 (CA)
Inventor: WIEDEMAN ROBERT A
IPC: H04B7/204
Filed: 1997-10-20
Abstract: The teaching of this invention pertains particularly to satellite communications systems using GSO or NGSO satellites. This invention employs data derived from signals of various types to derive a mathematical model of propagation related attenuation-inducing events so as to plan system resource allocation to minimize an amount of power required to close communication links between user terminals and the satellites. Disclosed are methods for modelling gateway to satellite links, as well as methods for modeling the user terminal to satellite links. This invention overcomes the problems inherent in the prior art by providing a direct measurement of severe path attenuation potential. The use of the teaching of this invention enables preplanning of the allocation of satellites and satellite resources by calculating a potential for signal path interference based on an external measurement of where rain attenuation may be located, and the real-time or approximately real-time tracking of rain cell activity within storm cells. Optimization of a global system of satellites is made possible, particularly in the context of a system of LEO satellites.

Abstract: Method and apparatus for testing and sampling open-hole oil and gas wells. The apparatus comprises a packer, a surge chamber, a closure valve which may be opened to flow fluid into the surge chamber, and a sampler. The surge chamber may be one of a pair of surge chambers, and the closure valve may be one of a pair of closure valves so that two surges may be carried out prior to obtaining a fluid sample in the sampler. In operation, the packer is placed in a set position by setting down weight. The closure valves are also actuated when weight is set down. The first closure valve has a first predetermined time delay before opening so that the packer may be set, and the second closure valve has a second predetermined time delay so that the packer may be set and the first closure valve opened before a fluid sample is captured. By opening a vent tool at an upper end of the uppermost surge chamber, formation fluid may be forced back into the formation or zone of interest by a bull-heading operation. In a preferred embodiment, portions of the apparatus are detachable in the event of sticking of the apparatus in the well. In the method of the two-surge test, a clean fluid sample for capturing in the sampler is provided. All of the steps are carried out without flowing fluid to the surface.

Title: Method and apparatus for scrambling and descrambling of video signals with edge fill
Inventor: RYAN JOHN O
IPC: H04N9/87
Filed: 1992-11-12
Abstract: A video-scrambling system induces a random wobble i.e., time shifting, in the location of active portion of the video frame, without affecting the horizontal sync signal and colorburst in each video line, thus providing both security and concealment.  The security is enhanced by filling in the gap between the nominal beginning of active video and the actual beginning of active video with a synthesized video signal which replicates the adjacent active video using a digitally generated filling pattern. Also, a random noise overlay further conceals the location of the gap.  Additional concealment is provided by wiggling in time the location of the horizontal sync signal using one or two frequencies and also by randomly altering the location of the vertical sync signal.  The NTSC digital encoding in accordance with the invention is simplified by using only two channels, chrominance and luminance, and by a heterodyne circuit for chrominance stability.  NTSC encoding is enhanced by providing detail normally lost, by use of the chroma channel.  Additionally, a non-standard video signal may be provided with a portion of the colorburst on the front porch of the horizontal blanking, thus allowing use of a relatively simple decoder.
Patent CA-2236339-A1 (CA)
Inventor: SAUER ROBERT T
IPC: C12Q1/6811
Filed: 1996-12-06
Abstract: A novel method for screening chemical compounds for potential pharmaceutical effectiveness is provided. The disclosed method identifies possible therapeutic test ligands by placing them in the presence of target proteins and determining the ability of test ligands to prevent the partial unfolding of the target protein by measuring the fluorescence emission of a conformation-sensitive probe. This differs significantly from known methods of novel pharmaceutical testing in that the biochemical function of the target protein need not be known and the existence of any known ligands of the target protein is unnecessary.

Title: Thermal spray using adjusted nozzle
Inventor: SITKO STEPHEN G
IPC: C23C4/10
Filed: 1996-11-27
Abstract: In a thermal spray apparatus (1) a plasma stream passes through a nozzle (2) towards a substrate (20). On entering the nozzle (2), the plasma stream passes through a plasma cooling passageway (10), to a plasma accelerating zone (11) defined by a narrowed passageway, and then into an expanded plasma/particle confining zone (12, 18) for the discharge of material from the nozzle (2). To apply thermal spray coatings (21) of increased hardness to a substrate (20), the ratio of length of the plasma/particle confining zone (12, 18) relative to the diameter of the plasma/particle confining zone (12, 18) is increased from the more conventional value to about 5:1, preferably to a ratio in the range of from 7:1 to 16.5:1. Ratios of from 10:1 to 13:1 have been found to achieve a particularly desirable result. Also the method and the coatings obtained.
