Title: Multifunction window blinds
Inventor: DE SILVA NICOLE ASANKA
IPC: E06B9/386
Filed: 2000-12-15
Abstract: A multifunction window blind is disclosed which can be strategically used to improve the efficiency of solar energy collection by a window of a dwelling for heating purposes during winter, as well as to improve efficiency of rejection of the sun's incoming radiation for cooling purposes, during summer or in a hot climate. Heat transfer properties of the blind can be conveniently switched from energy collection mode to rejection mode, depending on the time of day or weather conditions. The same blind can be used for selectively enhancing retention or dissipation of heat during the night according to the exterior weather conditions. The disclosed structure includes a window blind with slats with different energy-absorption and energy-rejection properties of the surfaces on their opposite sides. The disclosed multifunction blinds can be used in place of conventional blinds with minimal or no modification to the existing windows.
Patent CA-2329917-A1 (CA)
Inventor: ZHAO XIAODONG EDWARD
IPC: C09D11/00
Filed: 1999-04-14
Abstract: This invention relates to solid complexes of anionic dyes with quaternary ammonium compounds which have average molecular weights of below about 900 which are substantially free from unwanted salts. Of particular interest as quaternary ammonium compounds are those which comprise alkoxylated moieties.  Such complexes are formed through ionic bonds formed between the two compounds. The complexes are then removed of substantially all resultant unwanted salt formed from the cations of the dye and the counter-ions of the quat so as to obtain a solid dyeing agent which easily disperses within different media and which possess extremely good non-migration and coloring characteristics. This invention also concerns methods of making the aforementioned salt-free solid anionic dye/quat complexes as well as methods of utilizing such complexes for dyeing thermoplastic, thermoset, and wax compositions.

Filed: 1999-07-30
Abstract: A method and a receiver for equalization of received digital signals r(n) propagating in a scattered communication channel with multiple time-unvaryin g and also time-varying paths which give rise to time and frequency distortion s with channel pulsed response (CIR) having total length equal to L symbol intervals. In accordance with the method the scattered channel state is divided in three components and to wit the observable, close hidden and distant hidden states. The channel is then estimated on the basis of a vecto r p'(n) of the a posteriori probabilities (APP) of the observable state  b'(n) and on the basis of the received sequence r(n) and the received  symbol decision is made on the basis of a maximum a posteriori probability (MAP) based on the above mentioned APP vector p'(n) of the channel observable state. The CIR can be estimated in relation to a probe sequence contained in the received signal and the result of the estimate is used duri ng reception of the remaining part of the signal and if necessary updated if th e channel is time-varying.

Abstract: The invention relates to a device for producing autostereoscopically observe d images with perspective views of the object field thus detected. The surface  of the screen is composed of individual segments (pixels) that can produce three additive base colours. The pixels constitute the head of a height- adjustable pixel carrier. The pixel carriers can be individually controlled and adjusted at various heights (pixel heights). By controlling the pixel carriers in this manner, the pixels can be raised/and or lowered. Height effects can be produced in both the direction of the viewer and in an opposi te direction. Spacial depth information, e.g. from a z buffer, can be transform ed proportionally into pixel heights, i.e. without any intermediate steps. Current computer technology enables the image depth information to be used directly to convert said information into relief-shaped image depth, i.e. th e colour signals of the image, toegether with the image depth of the objects a s represented by the pixel heights, complete each other to form a new quality image.

Title: Method and apparatus for aligning and comparing images of the face and body from different imagers
Inventor: PROKOSKI FRANCINE J
IPC: A61B5/117
Filed: 2000-10-20
Abstract: A method and apparatus for comparing an infrared image of a person to a database of visual images of persons and calculating the probability that ea ch is a match to the infrared image is characterized by extracting minutiae fro m the infrared image and extracting visible minutiae from the visible images. Coincident minutiae which occur in both spectra are used to scale and regist er the infrared and the visible images. Other minutiae are spectrum-dependent, but must obey rules relative to minutiae of the other spectrum, due to the anatomical structure of the human face and body. The primary application is for identification of persons seen in infrared surveillance imagery, using a  reference database of visual images. Other applications includes compression  of talking head video and animation of synthetic faces. The method and apparatus can also be applied to areas of the body other than the face, to compare images from different spectra including images from medical sensors.

Abstract: An electrode and method of preparing an electrode by electropolymerizing a film on the conductive working surface of an electrode. The electrode is modified by reductive electropolymerization of a thin film of poly[Ru(vbpy)32+] or poly[Ru(vbpy)32+/vba](vbpy = 4-vinyl-4'methyl-2,2'- bipyridine and vba = p-vinylbenzoic acid) and the electrode is used for the electrochemical detection of aqueous GMP, poly[G], and the surface immobiliz ed single-stranded DNA probes. The film is formed from a co-polymer of a mediat or such as Ru(vbpy)32+ and a functionalized moiety having a carboxylate group such as p-vinylbenzoic acid. A DNA probe is attached covalently to the carboxylate group via a carbodiimide reaction followed by amidation of an amino-linked single-stranded DNA. In the presence of these guanine containin g moieties, a dramatic enhancement in the oxidative current for the Ru3+/2+ couple (present in the polymeric thin film) due to the catalytic oxidation o f guanine is observed.

IPC: H04L12/28

Abstract: An approach for performing congestion avoidance in a switching communication system is disclosed. An input port of the switching communication system receives a bandwidth request from a source. The switching communication system includes a bandwidth control processor that examines the bandwidth request, and multiple output ports. The output ports communicate with various destination sites. A congestion avoidance logic within the switching communication system generates multiple clusters based upon a transmission constraint associated with the output ports; each of the clusters corresponds to a portion of the destination sites. The congestion avoidance logic determines a cluster threshold that corresponds to traffic load distribution among the critical clusters. Additionally, the congestion avoidance logic selectively grants the bandwidth request based upon the determined cluster threshold. This congestion avoidance mechanism has applicability to a packet-switched satellite communication system with an on-board switch; the switch has transmission constraints such that the transmitters of the satellite at the output port of the switch cannot simultaneously transmit to downlink cells, which contain station terminals that are within an interfering distance from one another.
