Patents

Graded Zooming
Douglas R. Coffland
U.S. Patent 7,035,479 B2
April 25, 2006
This system, which includes a camera connected to a computer, increases the far-field resolution of video or still-frame images while maintaining full coverage in the near field. The computer applies a specific zooming-scale factor to each line of pixels. Then it continuously increases the scaling factor of the lines from the bottom to the top, thus capturing the scene in the near field and maintaining the scene’s resolution in the far field.

System and Method for Characterizing Voiced Excitations of Speech and Acoustic Signals, Removing Acoustic Noise from Speech, and Synthesizing Speech
Greg C. Burnett, John F. Holzrichter, Lawrence C. Ng
U.S. Patent 7,035,795 B2
April 25, 2006
The present invention is a system and method for characterizing human (or animate) voiced excitation functions and acoustic signals, removing unwanted acoustic noise that often occurs when a speaker uses a microphone in common environments, and synthesizing personalized or modified human (or other animate) speech on command from a controller. A low-power electromagnetic (EM) sensor is used to detect the motions of windpipe tissues in the glottal region of the human speech system before, during, and after speech is produced by a user. A voiced excitation function can be derived from these tissue motion measurements. In addition, the excitation function provides speech production information to enhance noise removal and allows accurate speech-transfer functions to be obtained. Previously stored excitation and transfer functions can be used to synthesize personalized or modified human speech. The EM sensor and acoustic microphone systems can be configured to enhance noise cancellation and measure multiple articulators.

U.S. Patent 7,038,844 B2
May 2, 2006
This amplifier includes a length of silica optical fiber that has a neodymium-doped core and two claddings, each with a succeedingly lower refractive index. The diameter of the first cladding is less than
10 times that of the core. The doping concentration of the neodymium is chosen so that the signal absorption for 816-nanometer light traveling within the core is less than 15 decibels per meter above the other fiber losses. The amplifier is optically pumped with one laser into the fiber core and with another laser into the first cladding.

Light is directed toward the first rotary table and the rotating ceramic component. A detector is located on a second rotary table. The second table is connected to the first rotary table and the rotating ceramic component. The second rotary table moves the detector at an angle to the first rotary table and the rotating component.

Solid-Phase Microextraction Fiber Cleaning and Conditioning Apparatus and Method
Armando Alcaraz, Michael H. Wiefel
U.S. Patent 7,047,661 B2
May 23, 2006
The solid-phase microextraction (SPME) fiber cleaning and conditioning apparatus has an elongated heating chamber with first and second opposite ends. The first end can receive an SPME fiber portion of an SPME device, and the second (send) end is a fluid outlet. A heater is used to heat the chamber and heat-treat an inserted SPME fiber. Contaminants and other particles are agitated, desorbed, and purged from the inserted SPME fiber by flowing a fluid through the chamber from the first end to the second end, away from the SPME device. In addition, turbulence may be produced in the flow at a location adjacent the first end to enhance agitation, desorption, and purging. A holder may also extend from the first end to support the SPME device in a substantially horizontal orientation when the SPME fiber is positioned in the chamber.

U.S. Patent 7,049,543 B2
May 23, 2006
In this method, laser ablation is used to define metals or dielectric films on the surface of a wafer, printed circuit board, or hybrid substrate. High-energy, ultrashort pulses of laser light are used to manufacture electronic circuits or electromechanical assemblies without affecting the material adjacent to the ablation zone.

High-Efficiency Spectral Purity Filter for EUV Lithography
Henry N. Chapman
U.S. Patent 7,050,237 B2
May 23, 2006
An asymmetric-cut multilayer diffracts extreme ultraviolet (EUV) light. A multilayer cut at an angle has the same properties as a blazed grating and has been demonstrated to have near-perfect performance. Rather than nanofabricating a grating structure with imperfections no greater than several tens of nanometers, a thick multilayer is grown on a substrate and then cut at an inclined angle using coarse and inexpensive methods. Effective grating periods can be produced that are 10 to 100 times smaller than those produced today, and the diffraction efficiency of these asymmetric multilayers is higher than conventional gratings. Using an asymmetric multilayer as a spectral purity filter does not require that the design of an EUV optical system be modified, unlike the proposed use of blazed gratings for such systems.

Durable Silver Thin Film Coating for Diffraction Gratings
Jesse D. Wolfe, Jerald A. Britten, Aleksey M. Komashko
U.S. Patent 7,054,065 B2
May 30, 2006
A durable silver thin-film coating on a nonplanar optical element has been developed to replace gold as a material for fabricating such devices. An optical element with this coating is more efficient and resistant to tarnishing. It can also be easily stripped and redeposited without modifying the underlying grating structure. The element improves the throughput and power loading of short-pulse compressor designs for ultrafast laser systems and can be used in a variety of optical and spectrophotometric systems, particularly high-end spectrometers that require maximized efficiency.
