Patent CA-2574982-A1 (CA)
Inventor: HARDING WARREN
IPC: H01Q15/16
Filed: 2007-01-22
Abstract: An ellipsoidal dish to be used to collect and spatially filter electromagnetic waves. The dish is quite similar to a common parabolic radio telescope but the dish component is ellipsoidal rather than parabolic in shape. Using an ellipsoidal rather than parabolic shape for the dish allows spatial filtering along the axis you would point the dish, so for example you could use it to collect information from a near object rather than a far one. One example use would be to collect electromagnetic brain waves from a human brain which would be located inches from the ellipsoidal dish, whereas a parabolic dish would typically be aimed at the stars or satellite TV  stations. It would have an antenna at the near focal point of the ellipsoid similar to how a common parabolic radio telescope would have an antenna at the focal point of the paraboloid. It would have wiring and electronics to put the signal from antenna to wire in a manner similar to a common parabolic radio telescope. The device is quite similar to the type of dish your TV might use to get satellite channels should you need a reference for envisioning it.  The prototype is of such a size and shape as to be suitable for collecting electromagnetic brain waves from a human brain. It would be somewhat similar in purpose to a medical EEG device but would provide the ability to closely analyze a particular piece of brain tissue. It could be used to analyze any such near electromagnatic signal. The device could be used in a manner similar to an EEG, or if advanced communication of thought becomes possible for more advanced uses. For example one could communicate graphics vizualized in the human mind to the computer screen, or operate a telepathic internet comprised of many people logged onto the current internet with such ellipsoidal dishes.

Title: Optimized liquid-phase oxidation
Inventor: DAVENPORT BRYAN WAYNE
IPC: C07C51/265
Filed: 2005-08-29
Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.

Patent CA-2594105-A1 (CA)
Inventor: BERGHOLM FREDRIK
IPC: G01J3/12
Filed: 2005-10-25
Abstract: The present invention relates to the production of instantaneous or non-instantaneous multi-band images, to be transformed into multi- or hyperspectral images, comprising light collecting means (11), an image sensor (12) with at least one two dimensional sensor array (121), and an instantaneous colour separating means (123), positioned before the image sensor array (121) in the optical path (OP) of the arrangement (1), and first uniform spectral filters (13) in the optical path (OP), with the purpose of restricting imaging to certain parts of the electromagnetic spectrum. The present invention specifically teaches that a filter unit (FU) comprising colour or spectral filter mosaics and/or uniform colour or spectral filters mounted on filter wheels (114) or displayed by transmissive displays (115), is either permanently or interchangeably positioned before the colour separating means (123) in the optical path (OP) in, or close to, converged light (B).  Each colour or spectral filter mosaic consists of a multitude of homogeneous filtering regions. The transmission curves (TC) of the filtering regions of a colour or spectral filter mosaic can be partly overlapping, in addition to overlap between these transmission curves and those belonging to the filtering regions of the colour separating means (123). The transmission curves (TC) of the colour or spectral filter mosaics and the colour separating means (123) are suitably spread out in the intervals of a spectrum to be studied. The combination of the colour separating means (123) and the spectral or colour or spectral filter mosaics produces different sets of linearly independent transmission curves (TC). The multiple-filter image captured by the image sensor (12) is demosaicked by identifying and segmenting the image regions that are affected by the regions of the multiple filter mosaic, and after an optional interpolation step, a multi-band image is obtained. The resulting multi-band image is transformed into a multi- or hyperspectral image.

Title: Mini-channel heat exchanger header
Inventor: SANGIOVANNI JOSEPH J
IPC: F28F9/24
Filed: 2005-12-28
Abstract: A heat exchanger includes a plurality of multi-channel heat exchange tubes extending between spaced inlet and outlet headers. Each heat exchange tube has a plurality of flow channels defining discrete flow paths extending longitudinally in parallel relationship from its inlet end to its outlet end.  The inlet header has a channel for receiving a two-phase fluid from a fluid circuit and a chamber for collecting the fluid. The chamber has an inlet in flow communication with the channel and an outlet in flow communication with the plurality of fluid flow paths of the heat exchange tubes. The channel defines a relatively high turbulence flow passage that induces uniform mixing of the liquid phase refrigerant and the vapor phase fluid and reduces potential stratification of the vapor phase and the liquid phase within the fluid passing through the header.

Title: Multiple-angle retroreflectometer
Inventor: STAUBER ERIK
IPC: G01N21/55
Filed: 2006-02-27
Abstract: A system and method for measuring the photometric retroreflectivity of materials. The system comprises a light source and a first optical pathway along which an illumination light beam travels originating from the light source, and ending at a retroreflective surface to be measured. A second optical pathway is provided along which a retroreflected beam travels back from the retroreflective surface to an aperture array that selects multiple annular areas to be further directed to multiple detectors, one detector for each annular area selected by the aperture. Each detector has a filter for the determination of photometric retroreflectivity. The retroreflected light reaching the detectors produces currents proportion to the intensity of the light. A high-gain current-to-voltage amplifier is used to provide voltage signal to an analog-to-digital converter that converts a voltage to a digital number. A processor is electrically coupled to the analog-to-digital converter with an accompanying memory on which is stored operating logic adapted to determine the photometric intensity of a predetermined pattern of the retroreflected beam incident to the array of apertures and detectors which defines the retroreflected light which propagates from the retroreflective surface at a predetermined observation angle.

Abstract: A method for protecting a peptide from peptidase activity in vivo, the peptide being composed of between 2 and 50 amino acids and having a C-terminus and an N-terminus and a C-terminus amino acid and an N-terminus amino acid is described. In the first step of the method, the peptide is modified by attaching a reactive group to the C-terminus amino acid, to the N-terminus amino acid, or to an amino acid located between the N-terminus and the C-terminus, such that the modified peptide is capable of forming a covalent bond in vivo with a reactive functionality on a blood component. In the next step, a covalent bond is formed between the reactive group and a reactive functionality on a blood component to form a peptide-blood component conjugate, thereby protecting said peptide from peptidase activity. The final step of the method involves the analyzing of the stability of the peptide-blood component conjugate to assess the protection of the peptide from peptidase activity.
