Patent number: 8134714Abstract: The invention provides a method and system for measuring the length of a reflective resonator, by analyzing an electromagnetic spectrum emitted therefrom. The emitted spectrum is used for estimating a first cavity length. This estimation is thereafter improved, by first computing at least one interference number for the spectrum, adjust this value to e.g. an integer or half-integer depending on the configuration of the resonator, and thereafter re-calculating the length of the resonator using the adjusted value of the interference number. The above is an efficient way of improving the accuracy in the determination of a physical property of a resonator.Type: GrantFiled: October 9, 2009Date of Patent: March 13, 2012Assignee: Acreo AB and System 3R International ABInventors: Anders Djupsjobacka, Hakan Dahlquist

Patent number: 6623015Abstract: A clamping chuck having a central receptacle and a disk arranged around the receptacle and which may be moved from a clamping position, whereby a draw bar inserted into the receptacle is clamped, to a releasing position wherein a draw bar is released from being clamped. The disk has a locking mechanism including a plurality of locking elements which are equally spaced in a circumferential direction. The draw bar is coupled to a brake such that the braking force of the brake is proportional to a pull on the draw bar. Thus, a high axial load on the draw bar causes a high braking force and a low load results in a low braking force.Type: GrantFiled: August 22, 2001Date of Patent: September 23, 2003Assignee: System 3R International ABInventors: Albrecht Paul Schill, Björn Pettersson
