Abstract: A heating apparatus includes at least first and second burners located in a combustion chamber wherein the burners are separated by a divider for deterring uncombusted fuel flowing from a firing burner to an area adjacent to a non-firing burner. In another aspect of the present invention, the burners are used to heat water in a multiple staged heater.

Abstract: The present invention provides a method and system for providing relevance-enhanced image reduction in computer systems. Using such a method and system, information including images can be displayed in a display area that is smaller than the display area for which the information was designed while accurately conveying the overall content of the information. A computer system in which the present invention operates includes a computer connected to a display device and a secondary storage device. A reducer is stored in the secondary storage device for execution by the computer. Additionally, data regarding an image to be displayed on the display device is stored in the secondary storage device. In operation, the computer receives data regarding an image to be displayed from the secondary storage device. The reducer reduces the image by first cropping the image and then scaling the image. Lastly, the computer displays the reduced image on the display device.

Abstract: Apparatus, methods, systems and computer program products are disclosed that detect when a user is interested in information presented on a display device. The invention then automatically presents additional information to the user about the information presented on the display device.

Abstract: Apparatus, methods, systems and computer program products are disclosed that determines what information presented on a computer display screen to a user most interests the user. The invention uses this information to correlate the topics of the displayed information and the user's interest to select additional information for the user. This additional information better matching the user's interest.

Abstract: Apparatus, methods, systems and computer program products are disclosed to assist a user of a display device to more quickly recover from a distraction causing the user to look away from the display device. The user is also assisted when navigating hypertext documents by the invention indicating where the user last looked in a restored, previously viewed hypertext document.

Abstract: A feature-based speech recognizer having a probabilistic linguistic processor provides word matching based on the entire space of feature vectors. In this manner, the errors and inaccuracies associated with the heretofore known feature-based speech recognizers, which provided word matching on less than the entire space of feature vectors, are overcome, thereby resulting in improved-accuracy speech recognition. The word matching may be on feature vectors computed either from segments or from landmarks or from both segments and landmarks. For word matching on segment-based feature vectors, acoustic likelihoods may be normalized by extra-acoustic likelihoods defined by at least one extra-acoustic ("not" or "anti") model. Context-dependent and context-independent acoustic models may be employed.

Abstract: Apparatus, methods, systems and computer program products are disclosed that automatically expands the computer displayed information that interests a computer user. Thus making the information easier for the user to see. The computer detects which area on a display device has the user's interest by using a gaze-tracking device to monitor where the user looks on the display. After determining which area interests the user the invention expands the display of the information in that area.

Abstract: A method for forming synthetic crystals of proteins in a carrier fluid by use of the dipole moments of protein macromolecules that self-align in the Helmholtz layer adjacent to an electrode. The voltage gradients of such layers easily exceed 10.sup.6 V/m. The synthetic protein crystals are subjected to x-ray crystallography to determine the conformational structure of the protein involved.

Abstract: A fuel heating system which employs an improved heat exchanger for reducing particulate emissions in diesel or kerosene fuel powered internal combustion engines. The fuel heating system encompasses an internal combustion engine having a fuel line, a cooling system having a coolant line, and the novel heat exchanger of this invention. The heat exchanger has a container for holding heated coolant to provide a heat source for the fuel. A helical fuel tube extends the length of the container, with its inlet and outlet ports located in close proximity at the same end of the container. The coolant inlet and outlet ports are located on opposite ends of the container, with the coolant inlet port located on the same end of the container as the fuel ports. The coolant outlet port is located at a higher elevation than the coolant inlet port to prevent air lock.

Abstract: A simulator (100) of an electrical power generating system in accordance with the invention includes a programmed electrical power system simulator (104) specifying at least one simulated electrical power generating element (200) for generating electrical power and at least one simulated contactor (202, 206, 210, 212 and 216) for connecting the at least one simulated electrical power generating element to at least one simulated load bus (208), a state of the simulated elements of the simulated electrical power generating system during simulated generation of electrical power and a simulated state of elements of the electrical power generating system in response to a simulated fault condition; an input (102) for inputting data to the programmed simulator relating to the simulated operation of the electrical power generating system; and an output (106) for outputting data from the programmed simulator including a display for displaying data outputted from the programmed simulator relating to simulated operation
