Abstract: An endoscopic surgery apparatus is provided, including a tubular member, a handle located on a proximal end of the tubular member, and one or more pivotable arms detachably connected to a distal end of the tubular member. The tubular member has channels along its longitudinal axis, wherein at least one of the channels is an optical channel and at least one other channel is an illumination channel. The arms have guiding channels adapted to receive surgical tools, which direct the surgical tools. The arms are interchangeable with other arms of different configurations. Also, said arms have an open and a closed position, such that when the arms are in the closed position an opening is defined allowing viewing of a surgical site via the optical channel.

Abstract: A system for orientation assistance and display of an instrument that is inserted or present in the natural or artificially produced hollow cavity (human, animal, object), and that is equipped with one or more sensor units. Multiple measurements of the 3D position of the instrument equipped with one or more sensor units are performed by positioning a measuring system, so that a precise orientation and positioning of the instrument in the body can be computed. The 3D position data are used to compute a virtual image of the instrument synchronously. The virtual images are then either projected directly in exact position onto the body surface of a person or combined in a body surface image (real video camera image of the patient) onto a monitor or superimposed (virtual or augmented reality). The system is especially appropriate for displaying for a user a medical instrument, such as a catheter or a rigid or flexible endoscope, in the body of a person in real time, extracorporeally and in correct position.

Abstract: An apparatus including a downhole tool for conveyance in a wellbore extending into a subterranean formation and method of use thereof. The downhole tool may include a turbo-alternator disposed in a passageway for drilling mud, and a controller to: track operating points of the turbo-alternator, determine from the operating points a flow rate of the drilling mud, and control a component of the downhole tool based on the flow rate.

Abstract: A locomotive diesel engine emissions control suite includes retarding fuel injection timing and heating the diesel fuel. Switch locomotives are now required to comply with USEPA emission standards under 40 CFR Part 1033 regulations. Retarding the fuel injection timing reduces peak temperatures during combustion which in turn reduces production of Nitrogen oxides (NOx) but also increases emissions of particulate matter (PM), Carbon Monoxide (CO), and Hydrocarbons (HC) in the exhaust. Unrelated efforts to reduce the smoke in diesel exhaust by pre-heating the diesel fuel showed an unexpected reduction in PM, CO, and HC. Such heating of the diesel fuel did not affect the reduction in NOx but reduced emissions of PM, CO, and HC to acceptable levels. Further experiments showed that two degrees of fuel injection retarding and fuel heated to 120 to 140 degrees Fahrenheit resulted in meeting the 40 CFR Part 1033 regulations.

Abstract: A method of transluminal surgery is provided, which utilizes an endoscopic surgery apparatus having pivotable arms attached by hinges on its distal end. The arms are interchangeable with arms of various configurations. The method includes the steps of inserting an endoscopic surgery apparatus into a body cavity of a patient, making an incision in the body cavity wall to allow access to the patient's abdominal cavity, and further inserting the apparatus through the incision. Surgery is performed at the desired surgical site and the apparatus is withdrawn into the body cavity where the incision is closed. Finally, the apparatus is withdrawn from the patient's body.

Abstract: The present invention relates to a context-based service look up, wherein a service instance, having a scope includes at least one service instance data set having a hierarchy of levels. A service consumer data set, having a hierarchy of levels is received from a service consumer, having a situation. Comparisons are made of each service consumer data set with each service instance data set, for the same level. Dependent on results of the comparisons, it is determined whether said situation of said service consumer matches said scope of said service instance.

Abstract: A method for use with a spreadsheet includes storing a cell object, where the cell object includes a location in the spreadsheet of a cell to which the cell object relates and a process associated with the cell, and performing the process on a complex object to produce a result, where the complex object includes a construct comprised of data and code. A display is generated for the cell that is based on the result.

Abstract: The invention relates to a method for optimizing the fuel consumption of an aircraft during flight. At a given point of the flight, a fuel excess (EXTRA) is determined relative to the statutory loads depending on the flight profile and weather conditions forecast for the rest of the flight. If the excess (EXTRA) is less than a given value (EXTRA-mini), for at least one of the forthcoming flight phases ({circle around (1)}, {circle around (2)}, {circle around (3)}), the speed of the aircraft is adjusted so as to increase the excess (EXTRA).

Abstract: A tug boat diesel engine emissions control suite includes modified fuel injectors including a fuel injection timing retard feature, and diesel fuel heating. Tug boats are now required to comply with USEPA emission standards under 40 CFR Part 94 regulations. Retarding the fuel injection timing reduces peak temperatures during combustion which in turn reduces production of Nitrogen Oxides (NOx) but also increases emissions of particulate matter (PM), Carbon Monoxide (CO), and Hydrocarbons (HC) in the exhaust. Heating the diesel fuel provides a reduction in increased PM, CO, and HC to acceptable levels. Experiments showed that a novel modification to a plunger in the fuel injectors providing up to six degrees of fuel injection timing retarding, and fuel heated to 120 to 140 degrees Fahrenheit, resulted in meeting the 40 CFR Part 94 regulations.
