Granted: 2009-06-30
Abstract: Display location calculation means and methods for calculating a display location are disclosed. It has become common for users to indicate a point o n a display in order to communicate with a machine. It is therefore necessary to be able to calculate the location on the display that is being indicated by the user. A display generator (123) is arranged in operation to generate a display in response to display data generated by a machine (111). A camera operable to generate image data representing at least part of the scene with in the field of view of the camera (which part, includes at least a portion of the display) is carried in a pointer device (103). Computation means (111, 113, 115) are arranged in operation to receive the image data and the displa y data and to calculate from these data sets the position and/or orientation o f the pointer device (103) relative to the display. A display location can the n be calculated from the calculated position and/or orientation.

Abstract: A ballast (10) for powering a gas discharge lamp load (30) comprises an inverter (100), an output circuit (200), and a fault detection circuit (300). During operation, fault detection circuit (300) monitors a first signal and a second signal within output circuit (300) and sets a fault threshold in dependence on the second signal. The second signal is indicative of the type of lamps in the load (30). In response to the first signal exceeding the fault threshold, fault detection circuit (300) issues a shutdown command directing the inverter (100) to cease operation.

Abstract: The method concerns the formation by simulation of a reference map of the spatial distribution of sedimentary deposits according to their composition, in a sedimentary basin during a sedimentary deposit sequence (during a given geological time interval) and allows in addition to obtain the topography of the terrestrial surface of the basin at the beginning and at the end of this period. - As input data, a map of the thickness of the studied sedimentary layer is available, known by interpreting the results of a seismic survey, data concerning the location and composition of sedimentary deposits on the borders of the studied sedimentary basin, obtained by interpreting the results of seismic surveys, measurements and observations and from physical parameters characterising the transportation of sediments (diffusion coefficients in the marine environment and continental fields) for the considered period.  This data set is applied to a stationary diffusion numerical model, and the output obtained is a map of the lithological composition of the sediments deposited during the studied sequence, the topology of the terrestrial surface for the entire basin, at the beginning and the end of the considered time period.  Applications in particular for locating hydrocarbon deposits.

Abstract: A gear hobbing cutter system (40) that includes a cutter head body (42) having a plurality of cartridge-receiving slots (90) arranged in pairs comprising an inside and an outside cartridge-receiving slot (50A and 50B). Each pair of inside and outside cartridge-receiving slots (50A and 50B) are capable of receiving a respective inside and outside cartridge assembly (10A and 10B). To ensure that the inside and outside cartridge assemblies are properly positioned within their respective cartridge-receiving slots, one of the dimensions, preferably the length (LI or LO), of the inside cartridge-receiving slot and its respective inside cartridge assembly of a pair is different than the outside cartridge-receiving slot its respective outside cartridge assembly so as to form an error proofing system. A deformable area (58) is provided between the cartridge-receiving slot (50) and the cutter head body (42). The deformable area (58) includes a flex area (58a') for controlling an amount of deformation of the deformable area when a clamping member (46) bears against a clamping pad (56). The invention provides for a cartridge assembly (10) including a cutting insert (12) that can be indexable to at least two cutting edges, thereby providing cost savings as compared to conventional cutter systems that use cutter blades that required to be entirely scraped when worn or broken.

Abstract: The technical field concerns an Aircraft Computer Screen that activates and display smoke expulsion situations in a computerized and automatic way. An Amalgamated computer and sensor codes table, working in conjunction with the control panel, will then pinpoints the source of fire to an accuracy of 96 to 1. The expulsion process is done by a pair of Smoke Hole mechanisms (prior art) working in 10-second open and close fluctuations until the fire crisis is over. The entire operation is seen executed and recorded on the Aircraft Computer Screen. Decisional situations such as counter-terrorist gas release are the control of the pilot. The pilot can optionally decide to exclude the flight deck from water foam damage and still protect the passengers from burning during on-fire landings. Future disasters can be avoided by a review of the Aircraft Computer Screen tapes.

Abstract: An apparatus for molding a plastic closure includes a male mold assembly (12) including a forming pin (14) and an outer pin sleeve (16) which cooperate with a female mold (20) for defining a mold cavity (22). To facilitate mechanical stripping of a molded closure from the forming pin (14), pressurized air is introduced into the molded closure through at least one air passageway which extends axially between the forming pin (14) and pin sleeve (16). By outwardly expanding and forming the plastic closure during ejection from the forming pin, forces to which the closure is subjected during ejection are significantly reduced, thereby desirably reducing the amount of cooling of the closure that is required during the molding cycle prior to ejection.  Significantly increased operating speeds for compression molding apparatus can thus be achieved.

Abstract: Disclosed are a rotor for generating vortex water flow that creates shear intensity for removing solid material adhered to the separation membranes during the processing of water containing pollutant material, and a filtering apparatus employing the same. The rotor consists of a first rotor having first blades and a second rotor having second blades. The first and the second blades are extended in a radial direction from a rotational axis thereof, and are disposed at positions different from each other in the rotational axis direction. The first blades and the second blades have widths different from each other in a circumferential direction around the rotational axis, or disposed at positions different from each other in a circumferential direction. Protrusions can be attached on outer surfaces of the first blades and/or second blades. The pollutant material adhered to the separation membrane can be removed effectively since various types of vortex water flow are generated over wide range, and the energy loss of the filtering apparatus is reduced.
