US Patent:

6679946, Jan 20, 2004

Filed:

Sep 27, 2001

Appl. No.:

09/967212

Inventors:

Andrew William Jackson - Boulder CO
Mark J. Dalberth - Lafayette CO

Assignee:

Optical Communication Products, Inc. - Woodland Hills CA

International Classification:

C30B 2508

US Classification:

117 84, 117 85, 117 86

Abstract:

A method and apparatus for determining substrate temperature and the mirror center of a film structure formed on the substrate utilizes a transmission intensity spectrum of light to determine mirror center and a normalized transmission intensity spectrum of light to determine substrate temperature. White light is transmitted through the substrate and the film structure during the film structure formation process. Also during the film formation process, a reflected light intensity spectrum is obtained using the same or another light source, for light reflected by the film structure. Substrate temperature and mirror center may be determined during formation of the film structure and, based on the measured temperature and mirror center, the mirror center may be adjusted by changing film formation conditions during the film formation process to vary the thickness of the films being formed. The method and apparatus find particular application in the in-situ monitoring and adjustment of distributed Bragg reflectors used as semiconductor mirrors.

Abstract:

A low thermal impedance optoelectronic device includes an optical cavity adjacent a low thermal impedance DBR that provides improved heat dissipation and temperature performance. The thermal impedance of the DBR may be reduced by increasing the relative or absolute thickness of a layer of high thermal conductivity material relative to a layer of low thermal conductivity material for at least a portion of the mirror periods. The thermal impedance may also be reduced by increasing the distance between phonon scattering surfaces by increasing the thickness of the high thermal conductivity layer, the low thermal conductivity layer or both.

Abstract:

Selectively oxidized vertical cavity lasers emitting at about 1290 nm using InGaAsN quantum wells that operate continuous wave below, at and above room temperature are reported. The lasers employ a semi-insulating GaAs substrate for reduced capacitance, high quality, low resistivity AlGaAs DBR mirror structures, and a strained active region based on InGaAsN. In addition, the design of the VCSEL reduces free carrier absorption of 1. 3 μm light in the p-type materials by placing relatively higher p-type dopant concentrations near standing wave nulls.

International Classification:

H04L 9/32
G06F 21/00

US Classification:

726 5

Abstract:

A method and system for authenticating answers to Domain Name System (DNS) queries originating from recursive DNS servers are provided. A verification component provides a verification that a DNS query originated from the recursive DNS server. An authoritative DNS server receives the query via a network, such as the Internet, and provides an answer to the query to an authentication component. The authentication component then provides an authentication, such as a digital signature, which confirms that the received answer was provided by the authoritative DNS server, and then communicates the answer and the authentication to the verification component via the network. The verification component then verifies that the authentication corresponds to the received answer and sends the answer to the recursive DNS server. When the verification component receives an answer in the absence of a corresponding authentication, the verification component drops the answer.

International Classification:

A61B 5/00
A61B 8/08

Abstract:

Provided is a non-invasive system and method for determining a fuel value for a target muscle and potentially at least one indicator muscle. The method includes receiving an ultrasound scan of a target muscle; evaluating at least a portion of the ultrasound scan to determine fuel value within the target muscle; recording the determined fuel value for the muscle as an element of a data set for the muscle; evaluating the fuel data set to determine a value range; and in response to the range being at least above a pre-determined threshold, establishing a target score for the muscle as based on an upper portion of the value range. The method may be repeated to identify ranges for a plurality of muscles, the muscle with the greatest range being identified as an indicator muscle. Based on these findings the muscles estimated fuel level, fuel rating and energy status may be determined. An associated system is also disclosed.

International Classification:

A61B 8/08
A61B 8/00

Abstract:

Provided is a non-invasive system and method of determining pennation angle and/or fascicle length based on image processing. An ultrasound scan image is processed to facilitate distinguishing of muscle fiber and tendon. The processed ultrasound scan image is then analyzed. The pennation angle and/or fascicle length is determined based on the analysis. An example method includes receiving an ultrasound scan image of at least a portion of a skin layer as disposed above one or more additional tissue layers, the image provided by a plurality of pixels. The method continues by introducing noise into the pixels of the image and thresholding the pixels of the image to provide a binary image having a plurality of structural elements of different sizes. The method continues with morphing the structural elements of the binary image to remove small structural elements and connect large structural elements. With this resulting image, the method distinguishes muscle fiber and tendon from remaining elements and determines the pennation angle and/or the fascicle length from the muscle fiber and the tendon. Associated apparatuses and computer program products are also disclosed.

Abstract:

Provided is a non-invasive system and method of determining muscle tissue quality based on image processing. The non-invasive system and method includes determining muscle intramuscular fat content. The methods includes receiving at least one ultrasound scan image of at least a portion of a skin layer as disposed above one or more additional tissue layers, the skin layer defining a horizontal axis and the image provided by a plurality of pixels. The method continues by blurring the pixels of the image and thresholding the pixels of the image to provide an image having a plurality of structural elements of different sizes and gray scale. The method continues with morphing the structural elements of the image to remove small structural elements and connect large structural elements. With this resulting image, the method distinguishes muscle tissue from remaining elements. A ratio of black to white elements is evaluated to determine the muscle tissue quality or intramuscular fat content. Associated apparatuses and computer program products are also disclosed.
