Patent number: 11411146Abstract: A particle layer is positioned over a light output surface of a light emitting diode. A transparent protection layer positioned between and in contact with the light output surface and the particle layer. The particle layer comprises a multitude of optically scattering or luminescent particles and a thin coating layer of transparent material coating particles of the multitude. The particles are characterized by a D50 greater than about 1.0 ?m and less than about 30. ?m; the coating layer has a thickness less than about 0.20 ?m. The protection layer is less than about 0.05 ?m thick and includes one or more materials different from material of the coating layer. The protection and coating layers can each include one or more metal or semiconductor oxides. Oxide precursor reactivities, with respect to the corresponding light output surface, are less for protection layer material than for coating layer material.Type: GrantFiled: October 8, 2020Date of Patent: August 9, 2022Assignee: Lumileds LLCInventors: Jens Meyer, Marinus Johannes Petrus Maria van Gerwen, Ronja Missong, Joerg Feldmann, Hans-Helmut Bechtel

Patent number: 7751905Abstract: An active fixation cardiac electrode lead having a fixation helix movably placed in a housing at the electrode lead's distal end so as to be extended out of the housing's distal end and retraced into an inner space enclosed by the housing. The housing has a wall and a protrusion formed in the wall that protrudes into the inner space into interspaces between windings of the fixation helix. The protrusion causes an axial movement of the helix when the helix is rotated around its longitudinal axis. The protrusion is an integral part of the housing's wall which is bent or embossed to form the protrusion.Type: GrantFiled: October 11, 2006Date of Patent: July 6, 2010Assignee: Biotronik CRM Patent AGInventors: Joerg Feldmann, Gernot Kolberg, Kerstin Taeubert, Carsten Schilk, Hartmut Lenski, Carsten Fruendt

Patent number: 7599747Abstract: A screw-in electrode probe for cardiological application comprises an oblong electrode body (1), a supply line (10) running therein, and an electrode head (3) on the distal end (2). The latter is provided with housing (5), a shaft (6) mounted therein so it is rotatable and axially displaceable, and a corkscrew-like screw-in electrode (4) on the shaft (6). A contact spring in the form of an essentially planar spiral spring (11) is situated between these components, whose leg ends (12, 13) are in sliding contact with the housing (5) or the shaft (6), respectively, while exerting a radially directed spring force (F).Type: GrantFiled: August 15, 2006Date of Patent: October 6, 2009Assignee: Biotronik CRM Patent AGInventors: Jörg Feldmann, Gernot Kolberg, Hartmut Lenski
