Patent CA-2484110-A1 (CA)
Inventor: CULLOM JAMES P
IPC: B07B1/55
Filed: 2004-10-07
Abstract: A material separator for separating at least two different materials of differing densities and/or sizes of particles. The material separator generally includes a tank containing a flocculent, a circulation system for circulating flocculent within the tank and a pair of conveyors for moving two different materials out of the tank. The tank may include an upper chamber and a lower chamber. At least a portion of each of the conveyors is located in the upper chamber to catch materials fed into the flocculent. Each of the conveyors may include a mesh belt that permits the flocculent to flow through the conveyor. The tank may include a clean out valve that permits fines and other debris accumulated within the upper chamber to pass into the lower chamber. The flocculent circulation assembly may include a nozzle that can be constructed in various configurations to create flows of flocculent of various velocities and trajectories. In one embodiment, the lower chamber includes a drag line assembly that removes fines and other accumulated debris from the lower chamber.
Patent CA-2485327-A1 (CA)
Inventor: STRICKER SAUL
IPC: B01D46/10
Filed: 2004-11-18
Abstract: The objective of this invention is to provide a means of reducing personal exposure indoors to certain airborne contaminants including particulates and chemicals including those given off or generated by the individual or by his activities and thus avoid subsequent symptoms caused by inhaling these materials. The invention is for use indoors by individuals with hypersensitivity to certain airborne contaminants. This invention provides a solution to the problem of reducing human exposure to suspended particles and other airborne contaminants in indoor air that a person breathes. The invention is an air filtering/cleaning device that creates a region of slow laminar flow of clean air in front of the outlet of the filter, directing clean air to the user's breathing zone.  The filter is for use by persons in bed or in a sitting location such as a desk or sofa. The slow, laminar flow does not cause discomfort to the user and at the same time displaces contaminated room air from the user's breathing zone.

Patent CA-2523345-A1 (CA)
Title: Watermarking
Inventor: DUTTA MITRAJIT
IPC: G06K9/00
Filed: 2004-05-07
Abstract: A structured watermark may be embedded in data by applying an irregular mapping of variations defined by the structured watermark to frequency domain values representing the data. In particular, the frequency domain representation of the data comprises an ordered set of frequency domain values. The structured watermark is used to define an ordered set of variations to be applied to the frequency domain values. Each variation is a value defined by the structured watermark. An irregular mapping from positions in the ordered set of variations to positions in the ordered set of frequency domain values is defined. This irregular mapping is one-to-one and invertible.  Application of the irregular mapping to the set of variations results in a set of values that may appear to be noise both in the frequency domain and in the signal domain of the data. The signal domain of the data may be n-dimensional, and may be a spatial, temporal or other domain from which data may be converted to the frequency domain. The signal domain of the data may be continuous or discrete. Each frequency domain value is modified by the variation mapped to the position of the frequency domain value by the irregular mapping. A frequency domain value may be modified using an additive or multiplicative operation. Using additive embedding, the modifications to the frequency domain values may be effected in the signal domain without computing the frequency domain values of the data by transforming, to the signal domain, the results of applying the irregular mapping to the set of variations. The watermark may be detected in target data by using the inverse of the irregular mapping on the frequency domain representation of the target data. Because the watermark is structured, it may be perceptible in the target data after the target data is processed by the inverse of the irregular mapping. A similarity metric, such as correlation, also can be used to detect the presence of the structured watermark in the processed target data.

Title: A technique for determining relative yaw using phase windup
Inventor: DEIMERT KIM
IPC: G05D1/08
Filed: 2005-12-12
Abstract: A technique uses "phase windup" to determine relative yaw of a craft from a plurality circularly polarized signals transmitted from one or more transmission sources.  A first difference in carrier phase measurements taken simultaneously at time t1 is determined for first and second circularly polarized signals from a given transmitting source A second difference is then determined from simultaneous carrier phase measurements taken at time t2. A third difference, which is the difference between the first and second differences, is then used to determine the relative yaw based on a difference in wavelengths of the two signals. If more than one transmitting source is in view, a mean average of the third differences associated with the respective transmitting sources may be used to determine the relative yaw.
