  • Patent number: 8271122
    Abstract: A method for monitoring a manufacturing tool features acquiring metrology data (“Step a”). Data is acquired for process variables for a first process step performed by the manufacturing tool (“Step b”). A mathematical model of the first process step based on the metrology data and the acquired data is created (“Step c”). Steps b and c are repeated for at least a second process step (“Step d”). An nth mathematical model is created based on the metrology data and the data for the process variables for each of the n process steps (“Step e”). A top level mathematical model is created based on the metrology data and the models created by steps c, d and e (“Step f”). A multivariate metric is calculated based on the top level model of step f and data from subsequent runs of the manufacturing tool. Service is performed if the metric satisfies a condition.

  • Patent number: 8244498
    Abstract: A method and system for partitioning (clustering) large amounts of data in a relatively short processing time. The method involves providing a first data matrix and a second data matrix where each of the first and second data matrices includes one or more variables, and a plurality of data points. The method also involves determining a first score from the first data matrix using a partial least squares (PLS) analysis or orthogonal PLS (OPLS) analysis and partitioning the first and second data matrices (e.g., row-wise) into a first group and a second group based on the sorted first score, the variance of the first data matrix, and a variance of the first and second groups relative to the variances of the first and second data matrices.

  • Patent number: 7187532
    Abstract: A device and a method for stabilising a metallic object of magnetic material. The metallic object is transported along a transportation path or plane. The plane includes a transportation direction and is parallel to the longitudinal direction of the object therein. A sensor is arranged to sense the valve of a parameter depending on the position of the object with respect to the plane. An electromagnetic actuator is arranged to apply a magnetic force to the object in respone to the sensed position. The magnetic force has a force component directed transversely to the transportation direction and transversely to the plane.

  • Patent number: 7052646
    Abstract: In accordance with the method and the device according to the invention, previous pure pyrotechnic primers for initiating the ignition charges (6a, 6b) of the oxygen lance igniters (13) are replaced by a small quantity of powdered zirconium (7). Zirconium is pyrophoric and therefore ignites, providing it has a sufficiently large surface area, in the presence of a sufficient quantity of pure oxygen, although in ordinary air it is no more flammable than ordinary wood.

  • Patent number: 5635646
    Abstract: A method measures the rotational speed of an engine turbocharger. A microphone picks up sound generated by the rotation of the turbocharger and a microphone signal containing signal components is supplied. Low-frequency signal components are filtered out from the microphone signal generated by engine operation including noise from valves, fans and gas flows. An electronic bandpass filter is tuned to the remaining signal component having the highest amplitude in the filtered microphone signal and the frequency of the remaining signal component having the highest amplitude is determined. With a knowledge of the turbocharger geometry, the value of the frequency of the remaining signal component having the highest amplitude is converted to the rotational speed of the turbocharger.

  • Patent number: 5459305
    Abstract: A monitoring method, such as time and/or passage monitoring method, in which individuals, such as physical persons, make contact with a stamping unit and therewith supply information to the unit, in which the information is preferably compiled. The method is mainly characterized by arranging existing units in a decentralized system in which each unit is separated physically from remaining units; and is further characterized in that each individual himself carries an updatable information carrier which includes unique information personal to the individual concerned, wherein updating of the information carrier can be effected upon contact with a stamping unit. The invention also relates to a system for carrying out the method.

  • Patent number: 5315933
    Abstract: A method of separating a sub-combat unit from a protective canister. The method comprises the steps of discharging the sub-combat unit from the protective canister by causing a displacement of a driving sabot within the protective canister. The driving sabot is displaced by an elevated gas pressure generated by the combustion of a gas-generating pyrotechnical charge. The displacement of the sabot imparts a trajectory to the sub-combat unit. The displaceable driving sabot is prevented, by arrest means interconnected between the driving sabot and the canister, from accompanying the sub-combat unit in its new trajectory. A division of the protective canister into a plurality of parts is caused. The division ensures a change in at least one of the trajectory and the velocity of the parts of the canister.

  • Patent number: 5295310
    Abstract: In a method for drying a particulate material, the material is supplied into a first drying conduit where it is dried and transported to a first cyclone by means of drying air. The material is separated from the drying air in the first cyclone. The separated material is supplied into a second drying conduit where it is dried and transported to a second cyclone by means of drying air. The material is separated from the drying air in the second cyclone. The drying air is discharged from the respective cyclone. The major part of the drying air discharged from the first cyclone is conveyed to a condenser so as to be subsequently supplied into a first drying conduit, while the remainder thereof is discharged. An amount of the drying air discharged from the second cyclone, which corresponds to this remainder, is conveyed to the condenser to be supplied into the first drying conduit. The remainder of the drying air discharged from the second cyclone is supplied into the second drying conduit.

  • Patent number: 5006994
    Abstract: The invention relates to a method and an apparatus for determining the specific fuel consumption of an internal combustion engine by measuring the change in weight of a pot containing fuel for consumption by the engine during a specific, selectable time. The apparatus for performing this method includes a data acquisition system equipped with a number of measuring points. Sensors at the measuring points feed, through the data acquisition system, signals representing the change in weight of the fuel pot, the speed of the engine and the torque of the engine into a computer. The computer is programmed for measuring at constant speed and constant torque, within selectable tolerances, and for measurement during a specific, selectable period of time. The method of the invention permits the use of statistical methods to assure reliable and accurate measurement results with the shortest possible measurement period, while providing high flexibility in interfacing with an operator or central computer system.
