Patent number: 8271122Abstract: 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.Type: GrantFiled: July 22, 2011Date of Patent: September 18, 2012Assignee: MKS Instruments, Inc.Inventors: Tamara Byrne, Lennart Eriksson, Svante Bjarne Wold

Patent number: 5635646Abstract: 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.Type: GrantFiled: July 20, 1995Date of Patent: June 3, 1997Assignee: F. Wennstrom System ABInventor: Lennart Eriksson

Patent number: 5459305Abstract: 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.Type: GrantFiled: May 18, 1993Date of Patent: October 17, 1995Inventor: Lennart Eriksson

Patent number: 5315933Abstract: 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.Type: GrantFiled: October 22, 1992Date of Patent: May 31, 1994Assignee: Bofors ABInventors: Lars Paulsson, Lennart Eriksson

Patent number: 5295310Abstract: 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.Type: GrantFiled: May 13, 1993Date of Patent: March 22, 1994Assignee: ABB Flakt ABInventor: Lennart Eriksson

Patent number: 5006994Abstract: 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.Type: GrantFiled: April 19, 1989Date of Patent: April 9, 1991Assignee: ASE Europe ABInventors: Kjell Andersson, Lennart Eriksson
