Patent number: 10371520Abstract: The present invention relates to a gyroscope sensor for detecting a rotational motion about a sensitivity axis and comprising means for quadrature compensation. The gyroscope sensor comprises a total inertial mass comprising a first inertial mass and a second inertial mass physically attached to each other and arranged such that a rotation of the first inertial mass about a detection axis caused by the coriolis force when the gyroscope sensor is subjected to a rotation about a sensitivity axis. The gyroscope further comprises a first drive structure having a displaceable drive frame which may cause a respective of the first or second inertial mass to rotate about the detection axis in order to compensate for quadrature errors originating from faulty coupling between a drive mode and a sense mode of the gyroscope sensor.Type: GrantFiled: December 17, 2015Date of Patent: August 6, 2019Assignee: RISE ACREO ABInventors: Gert Andersson, Erik Svensson, Borys Stoew, Nils Hedenstierna

Publication number: 20170284803Abstract: The present invention relates to a gyroscope sensor (102) for detecting a rotational motion about a sensitivity axis (104) and comprising means for quadrature compensation. The gyroscope sensor comprises a total inertial mass (105) comprising a first inertial mass (106) and a second inertial mass (108) physically attached to each other and arranged such that a rotation of the first inertial mass about a detection axis caused by the coriolis force when the gyroscope sensor is subjected to a rotation about a sensitivity axis. The gyroscope further comprises a first drive structure having a displaceable drive frame which may cause a respective of the first or second inertial mass to rotate about the detection axis in order to compensate for quadrature errors originating from faulty coupling between a drive mode and a sense mode of the gyroscope sensor.Type: ApplicationFiled: December 17, 2015Publication date: October 5, 2017Applicant: RISE Acreo ABInventors: Gert ANDERSSON, Erik SVENSSON, Borys STOEW, Nils HEDENSTIERNA

Publication number: 20170268879Abstract: A sensor is disclosed for detecting a rotational motion about a resulting sensitivity axis. The sensor includes at least two dual mass gyroscope units, each of the gyroscope units are adapted to detect a rotational motion about a sensitivity axis of the respective gyroscope unit. The sensitivity axes being parallel to each other and to the resulting sensitivity axis. The gyroscope units are interconnected at the inertial masses of the gyroscope units which cause the gyroscope unit to operate synchronously.Type: ApplicationFiled: December 17, 2015Publication date: September 21, 2017Applicant: RISE Acreo ABInventors: Gert ANDERSSON, Erik SVENSSON, Borys STOEW, Nils HEDENSTIERNA
