Publication number: 20120280675Abstract: Described are embodiments to ensure that the equipment utilized to detect antigens is reliable and accurate. Accordingly, one embodiment of the invention includes a calibration assembly having nanoparticles, with known magnetic properties, spaced apart at known y-axis locations along the calibration assembly. In one embodiment, the calibration assembly may be used to calibrate a matched filter of the write and read circuitry. Because the calibration assembly comprises nanoparticles with known magnetic properties the read response of the read circuitry to a particular nanoparticle may be stored in the matched filter as an ideal signal for that nanoparticle. The ideal signal stored in the matched filter may then be utilized for reliably and accurately detecting antigens.Type: ApplicationFiled: May 3, 2011Publication date: November 8, 2012Applicant: International Business Machines CorporationInventors: David Berman, Dylan Joseph Boday, Icko E.T.

Patent number: 7649710Abstract: In one embodiment, a tape read/write head supported by a lever is biased in a first position, using magnetic attraction between a magnet supported by the lever, and a return path structure of magnetically permeable material. In the illustrated embodiment, the magnet centers itself, in the absence of a coil generated magnetic field, in the middle of a gap of the magnetic return path structure. In one aspect, the mass of the read/write head and one side of the lever may be balanced by the mass of the magnet and the other side of the lever. The lever and hence the tape read/write head carried by the lever, may be pivoted by conducting current through a coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. As a consequence, the lever pivots on a pivot axis as a function of the magnitude and direction of the current through the coil.Type: GrantFiled: February 8, 2008Date of Patent: January 19, 2010Assignee: International Business Machines CorporationInventors: Nhan Xuan Bui, Reed Alan Hancock, David Howard Flores Harper, Wayne Isami Imaino
