In the shielding member 10, a plurality of the amorphous metal magnetic substances 10a are contained in the resin 12 at a volume fraction less than a percolation threshold. The type of the amorphous metal magnetic substance 10a is not particularly limited provided that the amorphous metal contains Fe, Si, and B.Type: GrantFiled: December 18, 2009Date of Patent: December 11, 2012Assignee: Empire Technology Development LLCInventors: Tomoaki Ueda, Masanori Abe

Patent number: 8283569Abstract: An electrode array, having application as a cochlear implant, includes a tube formed of Parylene defining a hollow channel. A substrate formed primarily of Parylene is supported by the tube. In turn, a plurality of metallic electrodes and feed lines are supported by the substrate. Numerous voids are defined by the tube which opens into the hollow channel. The size and spacing of the voids regulate stiffness and curl of the tube to provide excellent fit within the cochlea.Type: GrantFiled: January 22, 2010Date of Patent: October 9, 2012Assignee: The Regents of the University of MichiganInventors: Angelique Johnson, Kensall Wise

Publication number: 20120247827Abstract: The Protective Eyeglass Magnetic Sleeve for Cell Phone Radiation, provides a lightweight malleable rubber sheath worn over the arm of eyeglasses or sunglasses. It may also be applied directly to the telephone receiver itself or blue tooth devices. The sleeve is embedded with a series of small circular magnets measuring approximately five-sixteenths ( 5/16) of an inch. The magnets are strategically placed in the sleeve and alternately positioned positive to negative (+?), thereby generating a magnetic field designed to block the harmful electromagnetic waves emitted by cell phones, without compromising the quality of the voice signal being emitted.Type: ApplicationFiled: April 4, 2011Publication date: October 4, 2012Inventor: Pablo P. Gonzalez

Patent number: 8210481Abstract: There is provided a radiation shield device for providing radiation protection to an area, such as a spacecraft including, for example, a manned vehicle. The radiation shield device comprises a magnetic field generator, such as a solenoid, of superconductive material that provides a magnetic field around the area to shield the area from radiation. The solenoid preferably defines an axial length that is substantially smaller than a diameter of the solenoid. A thermal control system, comprising a limited amount of coolant or a refrigeration cycle, is included to control a temperature of the superconductive material during operation of the magnetic field generator. A magnetic shield device is also provided between the magnetic field generator and the area to be shielded from radiation to substantially shield the area from the magnetic field generated by the magnetic field generator.Type: GrantFiled: August 19, 2008Date of Patent: July 3, 2012Assignee: The Boeing CompanyInventor: Gary A. Kinstler

Publication number: 20110198118Abstract: A magnet wire has a conductor and a coating layer. The coated layer is coated around the conductor and has at least one magnetic coating layer; and at least one insulating coating layer. The magnetic coating layer has non-conductive magnetic material. The insulating coating layer and the magnetic coating layer are formed alternately. The alternative structure of the magnetic coating layer and the insulating coating layer prevent precipitation of magnetic material and efficiently offsets the interference between conductors after electricity is supplied, which inhibits occurrence of eddy current and lowers alternative current (AC) resistance.Type: ApplicationFiled: February 17, 2010Publication date: August 18, 2011Applicant: TA YA ELECTRIC WIRE & CABLE CO., LTD.Inventors: Tsang-Tse Fang, Han-Yang Chung, Chi-Feng Hung, Ting-I Lu, Kuang-Chiang Chou, Pa-Kuel Chuang, Chun-Hung Chen, Jung-Kun Chiu, Shang-Hui Shen
