Title: Positioning system and method
Inventor: SPEASL JERRY ALAN
IPC: G01S19/42
Filed: 1997-01-29
Abstract: A positioning system for locating objects in places where standard Global Position System signals do not penetrate. A first embodiment uses a GPS  receiver and a clock recovery unit. A computer receives the positional information and accurate time information. The computer calculates new orbital data for at least four pseudosatellites. The pseudosateliltes are antennas positioned in an interior or shielded space and function to send pseudosatellite data to a receiver. In a second embodiment, the positions of the pseudosatellites are provided to the computer without the use of a GPS  receiver. An accurate clock signal is also provided. The computer calculates orbital data for each pseudosatellite and transmits the time signal and ephemeris data for each pseudosatellite. The time signal is delayed for each pseudosatellite to account for propagation delays due to different connecting cable lengths.

Title: Coiled tubing screen
Inventor: RICHARD BENNETT M
IPC: E21B43/10
Filed: 1999-04-14
Abstract: One of the objects of the present invention is to allow a well to be produced through a screen without the need for a gravel pack. This objective is accomplished by the placement of an expandable screen that can move radially outwardly when placed at the desired location against the wellbore and be porous enough with sufficient open area to allow production from the formation. Another objective is to be able to easily place the screen in the desired location. This objective is met in one way by using coiled tubing which can be preperforated for a support for the screen. Another objective is to protect the screen during delivery to the desired location in the wellbore by a providing a disposable or removable outer cover which can be disposed of after proper location of the screen in the wellbore.

Patent CA-2272008-A1 (CA)
Inventor: TREPANIER FRANCOIS
IPC: G02B5/18
Filed: 1999-05-11
Abstract: A device and method for recording holographic gratings by the use of a single illuminating beam, two diffraction gratings, light detectors and a slit-scanning system. The beam illuminates two slits that then define two beams that are incident on the gratings. One diffracted order from one beam and one diffracted order from the other beam then interfere on a recording plane to produce sinusoidal variations of intensity. The interfering region may instantaneously be limited by a third slit. Also, another order of diffraction from one beam may be directed toward its own light detector and so is another order of diffraction from the other beam. These two detectors allow real time monitoring of the light intensity of each beam. By moving the slits in a direction parallel to the recording plane, an area larger than the slits' width can be exposed by the interfering pattern.

Title: Drill string diverter apparatus and method
Inventor: ROGERS HENRY E
IPC: E21B21/10
Filed: 1999-06-28
Abstract: The present invention relates to a drill string diverter apparatus for reducing surge pressure when lowering a liner into a partially cased wellbore. The diverter apparatus is connected in a pipe string above a liner being lowered into a wellbore. The diverter apparatus comprises a tubular housing with ports defined therethrough to communicate and redirect fluids received in the liner to the annulus between the diverter apparatus and casing previously set in the wellbore.      The diverter apparatus has an open position whereby the ports are open and communication is established and a closed position whereby flow through the ports is prevented. A sliding sleeve is disposed about an outer surface of the tubular housing and engages the casing. The sleeve moves vertically relative to the tubular housing once the diverter apparatus has been lowered into the casing to selectively open and close the flow ports. A J-slot means is provided for locking the diverter apparatus in its closed position.

Title: Method of pcr testing of pooled blood samples
Inventor: HELDEBRANT CHARLES M
IPC: B01L3/00
Filed: 1998-01-06
Abstract: Systems, processes, and devices are provided which are useful for testing blood or plasma donations to detect those specific donations which are contaminated by a virus above a predetermined level. An apparatus and process is described which forms individual, separately sealed and connected sample containers from a flexible hollow tubing segment connected to a fluid donation container. The tubing segment is sealed at spaced-apart intervals along its length, with tubing segment portions in the intervals between the seals defining containers, each of which holds a portion of a plasma sample. The contents of the containers are formed into pools which are subsequently tested for virus contamination by a high-sensitivity test such as PCR. The pools are tested in accordance with an algorithm by which a sample from each donation is mapped to each element of an N-dimensional matrix or grid. Each element of the matrix is identified by a matrix identifier, X rcs, where rcs defines the dimensional index. An aliquot is taken from each sample, and subpools are formed, each subpool comprising aliquots of samples in which one dimensional index is fixed. All of the subpools are tested in one PCR test cycle. The dimensional indicia of each positive subpool is evaluated mathematically in accordance with a reduction by the method of minors, thereby unambiguously identifying a unique element in the grid, thereby unambiguously identifying a uniquely positive blood or plasma donation.

IPC: H04J13/18
Filed: 1999-09-17
Abstract: A method and apparatus are disclosed for modulating a communication signal in a code division multiple access (CDMA) environment using orthogonal N by N  Hadamard spread spectrum codes. Orthogonal spreading codes are used that have lengths that are not a power-of 2 to provide additional channel variability for various multimedia applications and increase the flexibility of the number of channels/bandwidth relationship. The Hadamard codes are multiples of 4 (4n) and demonstrate a good cross-correlation property, making them very useful in the flexible design of code division multiple access (CDMA) systems. A transmitter encodes each of N data streams (N not being a power of 2), to be transmitted using a 4n codeword, N j. The received signal is passed through a filter matched to the characteristics of the appropriate codeword, N j, and PN spreading sequence.
