20140239948 | Apparatus and Method for In-Field Magnetic Measurements - A magnetic field verifier apparatus includes a magnetic field detection element configured to produce a voltage signal in response to an applied magnetic field wherein the voltage signal corresponds to the strength of the applied magnetic field. Substantially identical circuit boards or units are connected to a central unit or mother board to place magnetic field detection elements of each board or unit in an mutually approximately orthogonal relationship. A microcontroller is in communication with the voltage signal. The magnetic field verifier apparatus is configurable to sense particular field strengths at various frequencies and store the readings to provide the user with a reliable verification that a particular magnetic field strength has been produced in a particular environment. | 08-28-2014 |

20110199712 | Degaussing Apparatus with Highly Uniform Magnetic Field - Generation of an intense magnetic field to erase high coercivity magnetic media uses delivery of energy to a degaussing cavity. To conserve energy storage and delivery requirements and to obtain a desired magnetic strength generally uniformly within the cavity, strategic placement of supplemental turns at ends of the magnetic field generating coil wound around the cavity can promote uniformity. Construction of at least cavity ends from an adequate quantity of magnetically soft ferrous material can also promote uniformity. A combination of both approaches is possible. | 08-18-2011 |
20100007338 | Apparatus and Method for In-Field Magnetic Measurements - A magnetic field verifier apparatus includes a magnetic field detection element configured to produce a voltage signal in response to an applied magnetic field wherein the voltage signal corresponds to the strength of the applied magnetic field. A current source coupled to the magnetic field detection element provides a stimulating current for the magnetic field detection element that builds in a ramp-like progression. A microcontroller is in communication with the voltage signal wherein the microcontroller is configured to detect and control the ramping time of the magnetic field detection element and to sense after the ramping time the voltage signal from the magnetic field detection element. The magnetic field verifier apparatus is configurable to sense particular field strengths at various frequencies and store the readings to provide the user with a reliable verification that a particular magnetic field strength has been produced in a particular environment. | 01-14-2010 |
20090140086 | Method and Apparatus for Deforming Media - A system and method for deforming and puncturing magnetic storage media includes one or more pivot arms that support one or more rotationally driven rotatable members bearing multiple deforming members or punch points. The punch points impact the media, producing the deformation, while the rotational forces push the media through the system, and the pivot arms adapt to media characteristics and widths to protect against jams. The puncturing force may be adjustable. | 06-04-2009 |
