Title: Method and apparatus for filtering interference and nonlinear distortions
Inventor: OVADIA SHLOMO
IPC: H04N21/647
Filed: 1999-12-08
Abstract: Interference and/or nonlinear distortions are reduced in a signal communicated from a transmitter to a receiver. To reduce interference, the transmitter is momentarily disrupted, during which time the receiver analyzes interference on the communication path to determine the frequency of at least one peak thereof. Information is communicated from the receiver to the transmitter identifying the frequencies of the interference peaks. Based on this information, the transmitter pre-distorts the signal to accentuate the signal magnitude at the identified frequencies. The pre-distorted signal is then communicated to the receiver, where it is filtered to attenuate the signal magnitude at the identified frequencies. An adaptive scheme periodically determines the interference peak frequencies. For nonlinear distortion cancellation (e.g., CSO/CTB), there is no need to disrupt the transmitter since the frequencies of the distortion are already known. Pre-distortion at the transmitter and filtering at the receiver are performed at the known, fixed frequencies.
Patent CA-2292697-A1 (CA)
Title: Computer method utilizing free energy calculations for ligand design and the prediction of binding targets
Inventor: FREIRE ERNESTO
IPC: G16B15/30
Filed: 1998-06-02
Abstract: A computer-based method for the identification of binding targets in proteins and other macromolecules. More particularly, the invention includes an algorithm aimed at predicting binding targets in proteins. This algorithm, named Woolford, requires knowledge of the high resolution structure of the protein but no knowledge of the location or identity of natural binding sites or ligands. Binding targets in the protein are identified and classified according to their expected optimal affinities. Binding targets can be located at the protein surface or at internal surfaces that become exposed as a result of partial unfolding, conformational changes, subunit dissociation, or other events. The entire protein is mapped according to the binding potential of its constituent atoms. Once binding targets are identified, optimal ligands are designed and progressively built by the addition of individual atoms that complement structurally and energetically the selected target. This algorithm is expected to have significant applications in structure-based drug design since it allows: 1) identification of binding targets in proteins; 2) identification of additional targets if the primary target is known; 3) design of ligand molecules with optimal binding affinities for the selected target; and 4) refinement of lead compounds by defining the location and nature of chemical groups for optimal binding affinity.

Title: Tailored hierarchical cell structures in a communications system
Inventor: FRIED TOMAS
IPC: H04W36/06
Filed: 1998-06-05
Abstract: A server for use by a designated one of a number of mobile units in a cellular communications system including a plurality of cells having different service areas with respect to one another may be selected by, for each of the mobile units, assigning to each cell a category of preference for selection with respect to each other cell within the system, wherein for at least one of the cells, the assigned category of preference associated with a first mobile unit is different from the assigned category of preference associated with a second mobile unit. Then, for the designated mobile unit, the assigned category of preference for each of a number of candidate cells is determined. A first one of the candidate cells is then selected as serving cell for the designated mobile unit based upon whether the first one of the candidate cells has a higher category of preference than another of the candidate cells. Because categories of preference may differ for different mobile units, location-based services, based on categories of subscribers, may be provided. In other embodiments, a radio network may be optimized with respect to varying capabilities of installed radio base equipment.

Title: Method and apparatus for measuring thickness of coating layers on substrates using backscattering of x-rays and gamma rays
Inventor: MACKENZIE INNES K
IPC: G01B15/02
Filed: 2000-01-19
Abstract: The present invention provides a method and apparatus for non--destructive, in situ measuring thicknesses of layers on substrates. The method and device uses a probe including a radioactive source in a source holder and a photodetector mounted behind the source for detection of backscattered photons. In one aspect the method is used to measure the thickness of paint deposited onto metal substrates. The source holder and photodetector array forms a cylindrically symmetric probe for producing an axially symmetric beam of primary photons. A source containing radioactive 109Cd producing high energy photons of energy 22 and 25 keV is spaced from the painted surface so the photons impinge on the painted substrate. The intensity of photons backscattered by Compton scattering in the paint layer is proportional to the mass density of the paint to give a direct measurement of the paint thickness.    The photons penetrating through to the substrate are absorbed within the substrate. The device also provides a method for calculating the distance from the source holder to the substrate using backscattering of gamma rays.

Inventor: GROSSMAN BRUCE
IPC: C02F9/00
Filed: 1998-08-07
Abstract: A method and apparatus for purifying separate waste water from a dry cleaning process. The present invention utilizes 3 stages of purification. In Stage one, highly contaminated separator waste water (12) is put into a solvent separator tank (14). Liquid solvent (18) settles out of the separator waste water (12), sinking to the bottom of the solvent separation tank (14) where it accumulates below the separated water (20). In Stage 2 air bubbles are introduced through the separated water (20), stripping out much of the solvent which is dissolved in the separated water (20) and reducing the dissolved solvent concentration. This air stripping process dramatically extends the useful life of the granulated carbon in the granulated carbon filter (44), which results in the carbon purified water (46) having a dissolved solvent of less than 0.7 parts per million. The carbon purified water (46) can then be safely and economically disposed of without harming the environment.
