Patent number: 7523005Abstract: With a Coriolis mass flow meter a mass flow through a pipe is determined by exerting a force and/or moment on at least one location on the pipe, such that vibrations of several vibration modes are excited. The magnitude is determined of the force and/or the moment with which the pipe is excited. The response of the pipe is measured at multiple locations between two clamping points of the pipes, at excitations with several different frequencies. The sensitivity of the response to the mass flow is calculated on the basis of a model which comprises as free parameters the mass flow and model parameters which determine the sensitivity, wherein the mass flow and the model parameters are estimated that correspond with the combination of the force and/or the moment and the response measured for the different frequencies.Type: GrantFiled: May 11, 2004Date of Patent: April 21, 2009Assignee: Nederlands Organisatie voor toegepast-natuurwetenschappelijk Onderzock TNOInventor: Rolf Willem Bartstra

Patent number: 7482135Abstract: A method for determining whether a urine sample has been obtained from a subject suffering from a kidney disorder involving kidney damage. The method is based on determining the level of a proteolytic enzyme in urine from the subject. Sample and optionally comparing this level with a reference value. The proteolytic enzyme preferably is a matrix metalloproteases, in particular MMP-2 or MMP-9. The method is particularly suitable for subjects with a condition or disorder that is associated with an increased risk of kidney disorders, such as diabetes. The method may adavnatageously be applied for early detection of kidney damage, in particular when the subject does not yet show any sign of microalbuminuria.
