Patent number: 9786829Abstract: In one aspect, the present invention relates to a thermocouple device comprising a flexible non-planar substrate, a first printed thermocouple element comprising a first metal containing ink composition applied to the flexible non-planar substrate, and a second printed thermocouple element in electrical contact with the first printed thermocouple element making a thermocouple junction. The second printed thermocouple element comprises a second metal containing ink composition with a Seebeck coefficient sufficiently different from the first metal containing ink composition for the first and second printed thermocouple elements to together produce a thermocouple effect. The present application further relates to medical devices comprising the thermocouple and methods of making such devices.Type: GrantFiled: March 18, 2011Date of Patent: October 10, 2017Assignee: Micropen Technologies CorporationInventors: William J. Grande, Lori J. Shaw-Klein, Li Min

Patent number: 9236068Abstract: A hard bias (HB) structure for producing longitudinal bias to stabilize a free layer in an adjacent spin valve is disclosed and includes a composite seed layer made of at least Ta and a metal layer having a fcc(111) or hcp(001) texture to enhance perpendicular magnetic anisotropy (PMA) in an overlying (Co/Ni)x laminated layer. The (Co/Ni)x HB layer deposition involves low power and high Ar pressure to avoid damaging Co/Ni interfaces and thereby preserves PMA. A capping layer is formed on the HB layer to protect against etchants in subsequent process steps. After initialization, magnetization direction in the HB layer is perpendicular to the sidewalls of the spin valve and generates an Mrt value that is greater than from an equivalent thickness of CoPt. A non-magnetic metal separation layer may be formed on the capping layer and spin valve to provide an electrical connection between top and bottom shields.Type: GrantFiled: October 8, 2013Date of Patent: January 12, 2016Assignee: Headway Technologies, Inc.Inventors: Zhang Kunliang, Li Min, Zhou Yuchen, Zheng Min
