Patents

Integrated Electrical Connector
William J. Benett, Harold D. Ackler
U.S. Patent 6,897,557 B2
May 24, 2005
A sheet of electrically conductive material lies between two layers of nonconducting material that comprise the casing of an electrical chip. This electrical connector is attached to an electrical element embedded within the chip. An opening in the sheet is concentrically aligned with a pair of larger holes bored through the nonconducting layers. The opening is smaller than the diameter of an electrically conductive contact pin. The sheet is composed of flexible material so that the opening adapts to the diameter of the pin when the pin is inserted. The periphery of the opening applies force to the sides of the pin when the pin is inserted, thus holding the pin within the opening and in contact with the sheet using friction. The pin can be withdrawn from the connector by applying sufficient axial force.

Parasitic Oscillation Suppression in Solid State Lasers Using Optical Coatings
Eric C. Honea, Raymond J. Beach
U.S. Patent 6,904,069 B2
June 7, 2005
A laser gain medium has a layered coating on certain surfaces. This layered coating has a reflective inner material and an absorptive scattering outer material.

Solid Phase Microextraction Device Using Aerogel
Fred S. Miller, Brian D. Andresen
U.S. Patent 6,905,031 B1
June 14, 2005
A sample collection substrate of aerogel or xerogel materials bound to a support structure is used as a solid-phase microextraction (SPME) device. The xerogels and aerogels may be organic or inorganic and doped with metals or other compounds to target specific chemical analytes. The support structure is typically formed from a glass fiber or a metal wire (stainless steel or Kovar). The devices are made by applying gel solution to the support structures and drying the solution to form aerogel or xerogel. Aerogel particles may be attached to the wet layer before drying to increase the surface area of the sample collection. These devices are robust, stable in fields of high radiation, and highly effective at collecting gas and liquid samples, while maintaining superior mechanical and thermal stability during routine use. Aerogel SPME devices are advantageous for use in gas-chromatography and mass-spectrometry analyses because of their lack of interfering background and their tolerance for gas-chromatography thermal cycling.

Portable Pathogen Detection System
Billy W. Colston, Jr., Matthew Everett, Fred P. Milanovich, Steve B. Brown, Kodumudi Venkateswaran, Jonathan N. Simon
U.S. Patent 6,905,885 B2
June 14, 2005
This portable pathogen detection system detects multiple targets in biological samples onsite. The system includes microbead specific reagents, an incubation–mixing chamber, a disposable microbead-capture substrate, and an optical measuring and decoding unit. This system is based on a highly flexible liquid array that uses optically encoded microbeads as the templates for biological assays. Target biological samples are optically labeled and captured on the microbeads, which are in turn captured on a disposable substrate that has either an ordered or disordered array. The samples are then optically read.

Laser Driven Ion Accelerator
Toshiki Tajima
U.S. Patent 6,906,338 B2
June 14, 2005
This system and method for accelerating ions in an accelerator optimizes the energy produced by a light source. Several parameters can be controlled in constructing a target to adjust performance of the accelerator system. These parameters include the target’s material, thickness, geometry, and surface.

Halbach Array Generator-Motor Having Mechanically Regulated Output Voltage and Mechanical Power Output
Richard F. Post
U.S. Patent 6,906,446 B2
June 14, 2005
A generator–motor has its stationary portion (that is, the stator) positioned concentrically within its rotatable element (that is, the motor) along the axis of the rotor’s rotation. The rotor includes a Halbach array of magnets. The voltage and power outputs are regulated by varying the radial gap between the stator windings and the rotating Halbach array. The gap is varied by extensible and retractable supports that are attached to the stator windings and can move the windings in a radial direction.

Electronic Noncontacting Linear-Position Measuring System
Richard F. Post
U.S. Patent 6,906,528 B2
June 14, 2005
A noncontacting linear-position location system uses a special transmission line to encode and transmit magnetic signals to a receiver on the object whose position is to be measured. This invention is useful as a noncontact linear locator of moving objects. It can be used, for example, in determining the location of a magnetic levitation train for the operation of the train’s linear-synchronous motor drive system.

Application of the Phase Shifting Diffraction Interferometer for Measuring Convex Mirrors and Negative Lenses
Gary E. Sommargren, Eugene W. Campbell
U.S. Patent 6,909,510 B2
June 21, 2005
A reference beam and a measurement beam are both provided through a single optical fiber to measure a convex mirror. A positive auxiliary lens is placed in the system to provide a converging wave front on the convex mirror being measured. A measurement is taken that includes the aberrations of the convex mirror as well as the errors due to two transmissions through the positive auxiliary lens. A second measurement provides the information to eliminate this error. A negative lens can also be measured in a similar way. Again, there are two measurement setups. A reference beam is provided from an optical fiber, and a measurement beam is provided from a second optical fiber. A positive auxiliary lens is placed in the system to provide a converging wave front from the reference beam onto the negative lens being measured. The measurement beam is combined with the reference wave front and is analyzed using standard methods. This measurement includes the aberrations of the negative lens as well as the errors due to a single transmission through the positive auxiliary lens. A second measurement provides the information to eliminate the error.
