Publication number: 20130181794Abstract: Systems and methods are described for providing selective biasing of a platform in context of one or more modules. While moving in the Z-direction with respect to the modules, the platform travels in an unbiased manner. For example, one or more alignment features on the platform are engaged with one or more alignment features on the modules to allow the platform to substantially float within an X-Y region defined by the alignment features. When the platform reaches its desired Z-location, magnetic features bias the platform into a substantially locked and repeatable X-Y position (e.g., using permanent magnets and/or electromagnets). In some embodiments, the platform is locked into an accurate position to allow a robotic mechanism of a storage library to move around efficiently within the modules while still being able to perform operations that involve accurate positioning (e.g., pick and place operations on media cartridges).Type: ApplicationFiled: January 13, 2012Publication date: July 18, 2013Applicant: ORACLE INTERNATIONAL CORPORATIONInventors: Timothy Craig Ostwald, Joseph Paul Manes, Daniel James Plutt

Patent number: 8237526Abstract: Apparatus for inductive braking of a projectile are disclosed. Embodiments include a receiver that has a unidirectional conductor having a closed conductive pathway that encircles a passageway for a moving projectile. The unidirectional conductor permits current to flow through it in substantially only one direction around the passageway. As the projectile and its associated magnetic field move past the unidirectional conductor, the moving magnetic field induces a current flow through the closed conductive pathway, which in turn generates a magnetic field behind the projectile having the same polarity as the projectile's field. The two fields attract one another, which both exerts a braking force on the projectile and tends to align the two fields. Alignment of these fields centers the projectile away from the passageway wall.Type: GrantFiled: June 9, 2009Date of Patent: August 7, 2012Assignee: Sierra Lobo, Inc.Inventors: Philip Travis Putman, Kamel Salama

Patent number: 8212639Abstract: A haptic feedback system includes movable and static portions coupled by one or more magnetic fields that serve to retard movement of the movable portion with respect to the static portion so as to provide haptic feedback when the movable portion is moved relative to the static portion. A magnet associated with one of the movable and static portions reacts with structure associated with the other of the movable and static portions so as to provide haptic feedback when the movable portion is moved with respect to the static portion.Type: GrantFiled: January 30, 2012Date of Patent: July 3, 2012Assignee: TouchSensor Technologies, LLCInventors: John North, Deron Stambaugh

Patent number: 8212640Abstract: A magnetically driven tool includes a shaft having a bottom application end including a contacting surface, at least one support around a portion of the shaft for supporting components positioned outside the shaft that float with respect to the shaft. A first magnet is affixed to the shaft. An electromagnet secured to the support is positioned outside the shaft and floats with respect to the shaft above the first magnet. At least one bearing is provided for sliding the shaft in an axial direction and optionally rotating the shaft. For pushing operations, the direction of current through the electromagnet is applied so that like poles relative to the first magnet face one another to provide a repulsive force, while for pulling operations unlike poles face one another. The magnitude of the current sets a force applied by the contacting surface to a workpiece.Type: GrantFiled: July 26, 2011Date of Patent: July 3, 2012Inventor: Jerome Tuschner

Patent number: 8210893Abstract: One particular implementation of the present invention may involve a flexible material infused with fine iron particles to form at least a portion of a flexible character or object. The flexible creation may be animated by one or more magnets or electromagnets brought near the flexible creation such that the iron particles blended with the flexible material may interact with the magnetic fields generated by the magnets. The infused iron particles may be attracted to the magnets, causing the object or portions of the object to move toward or away from the controlling magnets, thereby animating the object or portions of the object. Another implementation may use a magnetic field of a magnet to create an iron-infused flexible plant-like object that may be animated by a magnet. The object may be constructed of a flexible iron-infused material that is introduced into the magnetic field while the material is in a liquid or semi-liquid state.Type: GrantFiled: December 30, 2008Date of Patent: July 3, 2012Assignee: Disney Enterprises, Inc.Inventors: Philip Jackson, Holger Irmler

Publication number: 20120139676Abstract: A magnetic field generator (10) comprising an assembly (20) of permanent magnets (30) inside which the magnetic flux concentrates. The assembly comprises opposed first and second elements (21, 22) that include magnets (30). The elements (21) and (22) are arranged substantially in the same plane and surrounded by respective closing mechanisms (51, 52). The permanent magnets (30) are made up of parallelepipedal blocks, arranged substantially in an arc of a circle according to three areas: a central area (60), a first side area (70) on one side of the central area (60), and a second side area (80) on the other side of the central area (60). The permanent magnets (30) of the first and second (70, 80) side areas have opposite directions of magnetization. Two parts (91) and (92) of a ferromagnetic material, forming a magnetic flux concentrator (90), are arranged on either side of the air gap (40).Type: ApplicationFiled: June 1, 2010Publication date: June 7, 2012Applicant: HAUTE ECOLE D'INGENIERIE ET DE GESTION DU CANTON DE VAUD (HEIG-VD)Inventors: Osmann Sari, Nathanael Alber
