Patent number: 8264134Abstract: An ultraminiature light source using a double-spiral shaped tungsten filament includes end contact portions which are separated to allow for radial and length-wise unwinding of the spiral. The double-spiral filament is spaced relatively far apart at the end portions thereof so that contact between portions of the filament upon expansion is avoided. The light source is made by fabricating a double-spiral ultraminiature tungsten filament from tungsten foil and housing the filament in a ceramic package having a reflective bottom and a well wherein the filament is suspended. A vacuum furnace brazing process attaches the filament to contacts of the ceramic package. Finally, a cover with a transparent window is attached onto the top of the ceramic package by solder reflow in a second vacuum furnace process to form a complete hermetically sealed package.Type: GrantFiled: June 7, 2010Date of Patent: September 11, 2012Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Margaret L. Tuma, Joseph S. Collura, Henry Helvajian, Michael D. Pocha, Glenn A. Meyer, Charles F. McConaghy, Barry L. Olsen, William W Hansen

Patent number: 6932933Abstract: A laser direct write method creates true three dimensional structures within photocerams using an focused pulsed ultraviolet laser with a wavelength in a weakly absorbing region of the photoceram material. A critical dose of focused laser UV light selectively exposes embedded volumes of the material for subsequent selective etching. The photoceram material exposure is nonlinear with the laser fluence and the critical dose depends on the square of the per shot fluence and the number of pulses. The laser light is focused to a focal depth for selective volumetric exposure of the material within a focal volume within the remaining collateral volumes that is critically dosed for selecting etching and batch fabrication of highly defined embedded structures.Type: GrantFiled: March 30, 2001Date of Patent: August 23, 2005Assignee: The Aerospace CorporationInventors: Henry Helvajian, Peter D. Fuqua, William W. Hansen
