Latest Patents

One of Rehberg's latest patents is for "Magnetic storage write heads using micro-electro mechanical shutters." This invention involves a write head for a magnetic storage system that energizes a write coil for multiple bit intervals. It selectively shutters the magnetic field to alter the magnetic domain of a magnetic storage medium for each bit interval. The position of the shutter is controlled using a micro-electro mechanical system, while magnetic pole segments provide a loop between the write coil and the magnetic storage medium. Additionally, magnetic shielding on the shutter mechanisms controls the reflection of the magnetic fields. In a rewritable magnetic storage system, a first write coil generates a positive magnetic field, and a second write coil generates a negative magnetic field. Each write coil has an associated shutter that selectively allows the positive or negative magnetic fields to alter the magnetic domain of the magnetic storage medium, effectively avoiding jitter.

Another significant patent is for "High-power electrical machinery." This invention features an electrical machine with a stator formed from a pair of cup-shaped permanent magnets symmetrically disposed on opposite sides of a conductive, disk-shaped rotor. The magnets are polarized so that a portion of their external magnetic flux passes in one direction through a short peripheral gap formed by the magnets, while the remainder passes in the opposite direction through a cavity defined by the inner volume of the cup-shaped magnets. The inner portion of the disk-shaped rotor is situated in this cavity. Various embodiments of the invention include the use of modified 'magic spheres' mounted on either side of the conductive disk-shaped rotor, as well as magnetic plates acting as mirrors for the cup-shaped magnets.
