Publication number: 20100034609Abstract: Method for reducing milling failure in a machining tool due to coincidence between first vibrations v1 substantially caused by mutually exerted forces between the machining tool and an object being machined, and second vibrations v2 substantially caused by mechanical resonance by or in the machining tool itself and/or one or more subsystems of the machining tool. The method comprising the steps of detecting frequencies of v1 and the frequencies of v2; determining the extent of the coincidence between the frequencies of v1 and the frequencies of v2. If the extent of coincidence between the frequencies of v1 and at least one of any of the frequencies of v2 is within a certain range, the vibration causing said coincidence between the frequencies of v1 and at least one of any of the frequencies of v2 is counteracted.Type: ApplicationFiled: March 10, 2008Publication date: February 11, 2010Applicant: Nederlandse Organisatie voor toegepast- natuurwetenschappelijk Onderzoek TNOInventor: Edward Jacobus Johannes Doppenberg

Patent number: 7614086Abstract: A monitoring apparatus, a computer program and a network are disclosed for monitoring a representation. The representation comprises a first data string. Subsequently, two or more output strings, based on the first data string, are generated by the monitoring apparatus such that the representative can not be reconstructed from just any of the output strings. The output strings are stored at separate storage locations. Each of the locations has different access rights from the other such that a party, authorized to solely access one such location and retrieve the single output string stored there, is unable to access the other location and retrieve the corresponding output string stored there. Consequently, that party, from just the single output string which it can access and retrieve, is unable to reconstruct the entire representation.Type: GrantFiled: March 19, 2002Date of Patent: November 3, 2009Assignee: Nederlandse Organisatie Voor Toegepast-Natuurwetenschappelijk Onderzoek TnoInventors: Boaz Simon Gelbord, Gerrit Roelofsen

Patent number: 7610822Abstract: On the basis of a series of reflection measurements on a liquid, parameters are calculated which describe a particle size distribution of particles in the liquid. In each reflection measurement, a signal beam is generated in the liquid and a value of a property such as the amplitude of a reflection on a particle in the signal beam is measured. Using maximum likelihood estimation, the parameters of the particle size distribution are estimated, on the basis of an expression for a probability of the measured values as a function of the measured values. The expression used contains a first factor for the probability of a reflection measurement of which a reflection with the measured value forms part, corrected with a second factor for the probability that there is not also a reflection with a dominating value of the property, which would mask the measured values, forming part of the reflection measurement.Type: GrantFiled: December 9, 2004Date of Patent: November 3, 2009Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk Onderzoek TNOInventor: Arno Willem Frederik Volker
