Patent number: 5706143Abstract: A magnetically actuated optical focusing device is provided. The focusing device comprises a housing with an optical component being displaceably and rotatably arranged therein. The optical component is ferromagnetically coupled, via an internal magnet arranged thereon, to an external magnet arranged outside of the housing, the external magnet being fixed to a focusing ring which is rotatably mounted on the housing. When the focusing ring is rotated, the ferromagnetic attraction between the magnets is sufficient to drive the internal magnet through a helical channel defined on the internal surface of the housing, thus causing the optical component to be longitudinally displaced within the housing. The helical channel exerts sufficient restraining force on the inner magnet so that the inner magnet remains in a particular position along the channel even if the ferromagnetic coupling between the magnets is broken down.Type: GrantFiled: June 14, 1996Date of Patent: January 6, 1998Assignee: Richard Wolf GmbHInventor: Klaus-Peter Hipp

Patent number: 5306467Abstract: A magnetic slide loading is used with automated cell counting equipment or manual optical microscopes to measure the number of cells in a fluid biological sample. A slide having a defined volume region holds the sample for measurement. A cover slip is placed over the defined volume region creating an enclosed volume. An actuable holder clamp is placed over the slide securing it as well as the cover slip in position by virtue of magnets secured to the bottom of the device exerting a magnetic force upon the holder clamp such that it is attracted toward the slide forcing the cover slip to flatten, thereby removing any defects or distortions from the volume. This action ensures that the volume has a uniform depth allowing accurate measurement of cell concentration within the biological sample.Type: GrantFiled: February 17, 1993Date of Patent: April 26, 1994Assignee: Hamilton-Thorn ResearchInventors: Diarmaid H.
