Title: Method of separating predetermined signal components from wireline acoustic array log data
Inventor: ZHANG JIAN-CHENG
IPC: G01V1/48
Filed: 1995-11-03
Abstract: A method for separating a predetermined wave propagation mode from signals generated by an acoustic array well logging tool is disclosed. Receiver signals from the tool are digitized and converted to a 2-dimensional (2-D) array. The 2-D array is converted to an (f,k) array by a 2-D Fourier transform. The (f,k) array is velocity bandpass filtered to separate the predetermined propagation mode. The filtered (f,k) array is converted back to the time-position domain by applying an inverse 2-D Fourier transform. In a particular embodiment of the invention, the filtered time-domain data are semblance correlated to determine  an acoustic velocity in the predetermined propagation mode in an earth formation.

Title: Tool Condition Monitoring System
Inventor: JONES JOEL W
IPC: G01R31/00
Filed: 1995-11-08
Abstract: A tool monitoring system monitors the condition of an electrically powered tool performing a cyclical operation. The tool monitoring system operates generally in two modes: learning mode and monitor mode. In learning mode, the tool monitoring system gathers statistical data on the power consumption of tools of the selected tool type during learning cycles. A power threshold is generated based upon the statistical data. The tool monitoring system then counts the number of crossings by each of the learning cycles of the power threshold and generates statistical data regarding the number of crossings. Preferably, the mathematical operation of wavelet packet transform is used to calculate the power threshold. Feature wavelet packets of the power consumption signal of the tool are calculated. The power consumption signal is then reconstructed from the feature wavelet packets and used to determine the power threshold. In monitor mode, the tool monitoring system counts the number of crossings of the power threshold by the power consumption signal of a tool in operation. The tool monitoring system identifies a worn tool when the number of crossings increases to a certain number relative to the crossings by the learning cycles.

Patent CA-2180795-A1 (CA)
Inventor: SYDOR JOHN TOM
IPC: H01Q3/08
Filed: 1996-07-09
Abstract: A compact, mechanically-steered antenna especially applicable for mobile terminals for receiving signals broadcast by satellites, is adjustable in azimuth and elevation. The antenna's active element can be rotated in azimuth through 360 degrees. Rotary couplings in the signal path are avoided by means of a flexible coupling. The flexible coupling conveniently comprises a torsion spring and the feedline, typically a highly-flexible coaxial cable, passes through it. The active element is mounted upon a first support member and rotatable relative to it about the boresight of the antenna. A second support member is mounted upon a base member and rotatable relative to it in azimuth. The first support is mounted upon the second support by means of a hinge coupling which permits pivoting of one support member relative to the other to adjust the elevation angle. Pivoting of the support members relative to each other is effected by longitudinal displacement of the flexible coupling which is fixed at one end to the antenna element and extends slidably through the second support member. A drive motor rotates the second support member and a linear actuator displaces the flexible coupling. Sensors detect the azimuthal angle.

Inventor: FUKUSHIMA TOMOAKI
IPC: H04B7/155
Filed: 1996-08-22
Abstract: A method and apparatus for controlling an antenna and a tracking antenna system using them. A rate sensor detects the angular rate of the vehicle turning. On the basis of the detected value, an error correction circuit determines the steering angle of the antenna. If it is judged from the determined angle that the vehicle is not turning or only slightly turning, a motor driving circuit suspends driving of a motor and at the same time a linear actuator locks a major gear. If it is judged that an accumulated error of a control target which is determined on the basis of the output of the rate sensor is not negligible, the error correction circuit starts a closed-loop control on the basis of a receiving signal level. In such a manner, the power consumption in the motor can be reduced.

Title: Method and apparatus for carrying out pre-treatment of wheat grains for flour milling
Inventor: SATAKE SATORU
IPC: B02B1/04
Filed: 1997-02-03
Abstract: Raw wheat grains are polished after being subjected to a first water addition and being tempered, and the polished wheat grains are ground after being subjected to a second water addition and being tempered.  The first water addition is to cause the raw wheat grains to have a water content of 12 - 14%.  The tempering of the raw wheat grains is performed for 16 - 36 hours so that the water sufficiently penetrate into the inside of the raw wheat grains.      The method of flouring includes the steps of measuring a water content of the flour obtained by the grinding of the grains, comparing the amount of the measured water content with a predetermined target water content of the flour, and adjusting the amount of water to be added during the second water addition if there is a difference between the measured water content and the predetermined target water content.  Thus, it is possible to reduce the time required for the tempering of the polished wheat grains and to adjust the second water addition based on the water content in the flour.

Filed: 1997-02-24
Abstract: In a method of administering a telephone local loop plant, a substantial portion-preferably at or above 80%-of the existing narrowband plant is caused to be "dedicated," so that constituent segments of an existing local loop therewithin are not allowed to be used to form other local loops when the existing loop is taken out of service. The remainder of the narrowband plant-the "non-dedicated" plant-is used to fill subscriber current orders for new service. Administration of the narrowband plant that has been dedicated is given over to an administrative system that is deployed to administer broadband facilities within the local loop plant. In preferred embodiment, the local loop plant is upgraded from narrowband to broadband in a way which gives priority to those geographical areas for which the costs of maintaining the narrowband plant are the greatest. The method, overall, provides a mechanism for reducing the costs associated with administering all of the narrowband plant using the legacysystems.

IPC: H04N5/21
Filed: 1996-06-12
Abstract: The present invention provides a method (200) and an apparatus (100) for spatially adaptive filtering for video encoding. The apparatus filters a video sequence prior the encoding process. The apparatus comprises a noise variance determiner (102), a local variance determiner (104), a noise visibility function determiner (106), a Gaussian kernel determiner (108), and a convolver (110). The apparatus removes noise directly from a Displaced Frame Difference, DFD, signal. This novel approach removes noise and miscellaneous high frequency components from the DFD signal without the introduction of the filtering artifacts characteristic of current techniques. By reducing the miscellaneous high frequency components, the present invention is capable of reducing the amount of information that must be encoded by the video encoder without substantially degrading the decoded video sequence.

Title: System and method for mapping chromatic dispersion in optical fibers
Inventor: MAMYSHEV PAVEL V
IPC: G01M11/00
Filed: 1997-05-28
Abstract: A system and method in which the chromatic dispersion characteristic, as a function of distance along a section of transmissive fiber, is measured. First and second optical signals are launched into a fiber under test to thereby generate, by a four-wave mixing process in the fiber, a probe signal.Because of a wave-vector phase mismatch, the probe signal power oscillates with a spatial frequency that can be measured as a function of distance in the fiber. The intensity oscillations are measurable as, for example, temporal variations in the Rayleigh backscattered light detected at the input end of the fiber. According to the present invention, the dispersion parameter at one or both of the first and second optical signal wavelengths, as a function of lengthalong the fiber, is derived directly from these intensity oscillation measurements. From this information, it is possible to further derive maps at other wavelengths of interest.
