Inventor: VIGEN ERIK
IPC: G01S1/00
Filed: 1995-12-20
Abstract: In a method for integrity monitoring in position determination by means of the Global Positioning System (GPS), especially by means of differential GPS  (DGPS) or multi-station DGPS, wherein there is employed a monitor station (M) with a first GPS receiver, provided at a location with a known geographical position, GPS-based position measurement results are transferred on a communication line from the monitor station (M) to a user location (F) the integrity of whose geographical position has to be monitored by means of a second GPS receiver provided at the location (F).

Title: Scintillation crystal modules and methods of making the same
Inventor: HUTH SCOTT T
IPC: G01T1/20
Filed: 1997-07-04
Abstract: The invention provides a scintillation crystal module having an epoxy seal which has a coefficient of thermal expansion which is substantially the same as the backcap of the gamma camera. Among the suitable epoxy systems, the CTE of the epoxy could be modified somewhat by choosing a different catalyst or by adjusting the resin:catalyst ratio. The presently preferred epoxy system is a STYCAST R 2850 FT system available from W.R. Grace & Co. Using "catalyst 9" or "catalyst 11" from that system, a CTE of approximately 17.33x10-6 to approximately 19.4x10-6 in/in°F can be easilyachieved. It has been discovered through analysis using FEA that an epoxy with a CTE in the range of 9.0 to 20.0x10-6 in/in°F provides satisfactoryresults in preventing seal separation during +40°F temperature cycles. A method of making a scintillation crystal module according to the invention includes the preparation of an epoxy seal having a coefficient of thermal expansion which is substantially the same as the backcap of the module, and assembling the seal, backcap, glass, and crystal in a conventional manner.

Title: Apparatus and method for canceling acoustic echoes including non-linear distortions in loudspeaker telephones
Inventor: DENT PAUL WILKINSON
IPC: G10L21/0224
Filed: 1996-02-20
Abstract: An echo canceling loudspeaker telephone includes a loudspeaker which produces a sound pressure wave in response to an input signal which is applied to an audio input. thereof. This sound pressure wave includes a desired linear component which is a linear function of the input signal, and an undesired non-linear component which is a non-linear function of the input signal, and the sound pressure wave is transmitted along an acoustic path. A microphone is positioned in the acoustic path and converts the sound pressure wave into an output signal. An echo filter is responsive to the input signal and generates an estimated echo signal. This echo filter includes a loudspeaker model which generates an estimate of the sound pressure: wave including an estimate of the linear component and an estimate of the non-linear component.      This echo filter also includes an acoustic path model which generates an estimate of the acoustic path from the loudspeaker to the microphone. In addition, a subtractor subtracts the estimated echo signal from the output signal thereby reducing an echo portion of said sound signal.

Title: Method for determining resistivity derived porosity and porosity derived resistivity
Inventor: DUNHAM LANNY L
IPC: E21B47/00
Filed: 1997-10-14
Abstract: An improved model and method for analyzing oil and gas well logs is disclosed. This method allows a log analyst to make an accurate interpretation of a well log in oil and gas bearing shaly sand formations by providing a means to correct for missing or faulty data. The present invention provides an improved model and method for determining resistivity when porosity is known and for determining porosity when resistivity is known. This methodology allows the determination of water saturation in a shaly sandstone formation using either resistivity, bulk volume clay or porosity data as a single input. Resistivity data can be corrected using density porosity. The combination of both resistivity and density porosity data in any well will allow corrections to questionable open hole log data. Correction of resistivity data for conductive clays, thin bed effects and hole angle is allowed.
Patent CA-2219365-A1 (CA)
Inventor: ROMER RONALD LOUIS JR
IPC: G01N17/00
Filed: 1997-10-24
Abstract: A device of testing the durability of a surface under accelerated conditions is disclosed. The device provides for testing the surface, such as paint markings from a paint, under simulated environmental conditions which are akin to those experienced by the paint markings applied on the working substrates, such as road surfaces. The device includes one or more wear wheels which roll preferably in a circular motion over a test pattern of the paint markings applied over a test substrate which is similar to a working substrate, such as a road surface. The wear wheel rolls under pressure through a desired number of rotations over the test pattern of paint markings. The pressure is adjusted to simulate the pressure exerted on the actual traffic paint markings on the road surfaces by vehicles driving thereon. The path of the rolling wear wheels allows the user to simultaneously compare the durability of several experimental paints by exposing each paint marking from the various experimental paints to the same speed and pressure that results in the same degree of wear. The path of the rolling wear wheels allows the user to simultaneously expose paint markings from several experimental paints to the same degree of wear under the same speed and pressure.
