Patent CA-2308213-A1 (CA)
Inventor: GOLDBERG DAVID A
IPC: G06F3/033
Filed: 1998-10-22
Abstract: An optical-input print reading device (29) with voice output (47, 63) for people with impaired or no vision in which the user provides input to the system from hand gestures. Images of the text to be read (37, 51), on which the user performs finger- and hand-based gestural commands, are input to a computer, which decodes the text images into their symbolic meanings through optical character recognition (55), and further tracks (57) the location and movement of the hand and fingers in order to interpret the gestural movements into their command meaning. In order to allow the user to select text and align printed material, feedback is provided to the user through audible and tactile means. Through a speech synthesizer, the text is spoken audibly. For users with residual vision, visual feedback (71) of magnified and image enhanced text is provided. Multiple cameras of the same or different fields of view can improve performance. In addition, alternative device configurations allow portable operation, including the use of cameras located on worn platforms, such as eyeglasses (100), or on a fingertip system (123). The use of gestural commands is natural, allowing for rapid training and ease of use.  The device also has application as an aid in learning to read, and for data input and image capture for home and business uses.

Title: High throughput method for functionally classifying proteins identified using a genomics approach
Inventor: SALEMME FRANCIS R
IPC: C40B30/04
Filed: 1998-11-12
Abstract: The present invention provides a method for functionally classifying a protein that is capable of unfolding due to a thermal change. The method comprises screening one or more of a multiplicity of different molecules for their ability to shift the thermal unfolding curve of the protein, wherein a shift in the thermal unfolding curve indicates that the molecule binds to the protein or affects the stability in a measurable way; generating an activity spectrum for the protein wherein the activity spectrum reflects a set of molecules, from the multiplicity of molecules, that shift the thermal unfolding curve, of the protein and therefore are ligands that bind to the protein, comparing the activity spectrum for the protein to one or more functional reference spectrum lists; and classifying the protein according to the set of molecules in the multiplicity of different molecules that shift the thermal unfolding curve of the protein.
Patent CA-2310427-A1 (CA)
Title: Epoxidation process using serially connected cascade of fixed bed reactors
Inventor: DANNER JEFFREY B
IPC: C07D301/04
Filed: 1998-09-23
Abstract: An olefin epoxidation process is operated using a plurality of reactor vessels, each containing a fixed bed of a heterogenous catalyst such as titania-on-silica. The reactor vessels are connected in series whereby a feedstream comprised of olefin and an active oxygen species is passed through said series of reactor vessels in contact with the heterogenous catalyst to accomplish conversion of the olefin to the corresponding epoxide. As the activity of the catalyst in an individual reactor vessel falls to an undesirably low level, said reactor vessel is taken out of service and a replacement reactor containing fresh or regenerated catalyst introduced. The replacement reactor vessel may, in alternative embodiments of the process, be the first or the last reactor vessel in said series. For example, the feedstream may first be contacted with either the most active or the least active charge of catalyst within the series of reactor vessels. Although the latter embodiment permits somewhat longer catalyst life, the former embodiment requires much smaller capacity heat exchangers. The process of this invention considerably reduces catalyst usage as compared to a conventional fixed bed epoxidation process where all of the catalyst is replaced or regenerated at the same time.

Title: Crop header with draper canvas
Inventor: SHEARER BRUCE ROBERT
IPC: A01D57/20
Filed: 2000-06-08
Abstract: A header includes a generally C-shaped cutter bar supporting the sickle knife assembly across a front edge of the header. A draper assembly is carried behind the cutter bar and includes a pair of rollers at right angles to the beam carrying a continuous draper canvas band around the rollers with the front edge of the canvas underneath the cutter bar. The rollers and a support plate between the rollers for the upper run of the canvas are both recessed relative to the front edge of the canvas to leave a cantilever portion at the front edge of the canvas which projects under the cutter bar to forma seal. The position of the draper canvas on the rollers is guided by a pair of longitudinally extending ribs one adjacent but spaced rearwardly from the front edge and abutting the trailing edge of the cutter bar and the other adjacent but spaced forwardly from the rear edge and abutting a front edge of a rear plate. The ribs are formed integrally with transverse slats. The front rib forms a damming effect reducing the possibility of material sliding over the front edge of the draper. An upper surface of the front rib can be castelated to provide an increased aggressive action tending to pull the crop along the draper.

Title: Fouling inhibition
Inventor: WILLIAMS DAVID NEIL
IPC: C09D5/16
Filed: 1998-12-23
Abstract: A process for inhibiting the fouling of a substrate in a fouling environment, which comprises forming on the substrate, before exposure to the said environment, a coating comprising a film-forming polymer (A) carrying unreacted curable silicon-containing functional groups providing latent reactivity, and thereafter applying a layer comprising a curable polymeric fouling-inhibiting material (B), more especially a curable polysiloxane or a curable fluorine-containing polymer, and bonding the applied layer to the said coating by a condensation curing reaction involving the unreacted functional groups thereon. The initial coating can be applied over a range of worn or damaged anti-fouling coatings. The sequential application of layers is a simpler, more flexible and more controllable procedure than is offered by complex systems designed to produce outer siloxane-rich regions. Relatively long latency periods are achievable.

Title: Multiple-valued logic circuit architecture: supplementary symmetrical logic circuit structure (sus-loc)
Inventor: OLSON EDGAR DANNY
IPC: H03K19/00
Filed: 1999-05-21
Abstract: Circuit structure and resulting circuitry for multiple-valued logic. The circuit structure allows the design and fabrication of any r-valued logic function of n-places where r is an integer greater than I and n is an integer greater than 0. This structure is called SUpplementary Symmetrical LOgic Circuit structure (SUS-LOC). In circuits incorporating SUS-LOC, circuit branches are realized that uniquely deliver circuit response and output. For some circuits, and due to the operating characteristics of the switch elements, additional circuit elements, or stages, must be incorporated to prevent "back biasing". SUS-LOC is fully active. Only active elements perform logic synthesis and those components not directly related to logic synthesis, such as resistors and/or other passive loads, are relegated the task of circuit protection.  The fabrication of r-valued, multi-valued, or multiple-valued logic circuits, designed using the definitions of the SUS-LOC  structure can be accomplished with known techniques, materials, and equipment.
