Publication number: 20050150278Abstract: A method of obtaining a material property of a pavement material from a microwave field generally includes generating a microwave frequency electromagnetic field of a first mode about the pavement material. The frequency response of the pavement material in the electromagnetic field can be measured, such as by a network analyzer. The measurement of the frequency response permits correlating the frequency response to a material property of the pavement material sample, such as the density. A method of correcting for the roughness of a pavement material divides the pavement into a shallow layer and a deep layer. Two planar microwave circuits measure the permittivity of the shallow and deep layer. The permittivities are correlated to correct for roughness. An apparatus for obtaining the density of a pavement sample includes a microwave circuit and a network analyzer. The network analyzer measures the frequency response to determine the density of the pavement material.Type: ApplicationFiled: October 22, 2004Publication date: July 14, 2005Inventors: Robert Troxler, William Joines

Publication number: 20050150299Abstract: General algorithms are developed for reconstructing the acoustic field generated by an arbitrary object subject to an arbitrarily time-dependent excitation. These algorithms enable one to visualize a time-domain acoustic pressure wave as it travels through three-dimensional space. Such a tool can be used to diagnose general noise sources and transmission since in engineering applications most structures are subject to arbitrarily time-dependent excitations. To facilitate the derivations of the temporal solutions, we make use of Laplace transform and expand the acoustic pressure in terms of the spherical Hankel functions and the spherical harmonics. The expansion coefficients are settled by solving an over-determined system of equations obtained by matching the assumed-form solutions to the measured acoustic pressures.Type: ApplicationFiled: January 8, 2004Publication date: July 14, 2005Inventor: Sean Wu

Publication number: 20050150320Abstract: A transmission device capable of changing speed with stored energy drives a carriage to move back and forth. The transmission device includes a variable speed transmission mechanism mounted on a base and driven by a motor. A first energy storage mechanism mounted on the variable speed transmission mechanism cooperates with a first latch mechanism mounted on the base so as to store and release the energy of the driven carriage, switch the output of the variable speed transmission mechanism, and thus switch the moving speed of the carriage.Type: ApplicationFiled: January 11, 2005Publication date: July 14, 2005Inventor: Chuang-Hua Chueh

Publication number: 20050150322Abstract: A rotatable member is adapted for dynamic balancing by the addition of balancing weights in the form of high speed projectiles fired at the member during rotation in timed relationship with the rotation of the member so as to impact the member at specific circumaxial locations required for balancing the member. The member has an annular groove for receiving the projectiles and securing the same at the desired locations. The groove has a cross sectional configuration slightly smaller than that of the projectile in at least one direction of measurement so as to engage and capture the projectile in retention in the groove.Type: ApplicationFiled: January 9, 2004Publication date: July 14, 2005Inventors: Drew Rocky, Russel Marvin, John O'Connor

Publication number: 20050150323Abstract: A composite-based rim includes multiple fiber-based, commingled layers wherein the strength and/or stiffness increases from the innermost to the outermost layer of the rim, but wherein the radial stress and strain generated in the rim decreases from the innermost to the outermost layer. At least some layers have a mixture of carbon fiber tows and glass fiber tows. The ratio of carbon fiber tows to glass fiber tows in each layer is constant, and the distribution of carbon fiber tows is macroscopically uniform in each layer.Type: ApplicationFiled: December 30, 2004Publication date: July 14, 2005Inventor: Ward Spears

Publication number: 20050150325Abstract: A drive axle assembly includes an input operably coupled to a power source. The input drives first and second axle shafts, which in turn drive laterally spaced wheel ends. Each wheel end includes a gear set that is driven by one of the axle shafts. The axle shafts are enclosed within a center axle housing and the gear sets are enclosed within gear housings. The drive axle includes a pumping mechanism that maintains predetermined oil levels within the center axle housing and gear housings. The oil level in the center axle housing is lower than the oil level in the gear housing. The pumping mechanism includes an impeller that is mounted for rotation with the axle shaft. The impeller draws oil from the center axle housing into a cavity, which transfers the oil to the gear housing.Type: ApplicationFiled: January 8, 2004Publication date: July 14, 2005Inventor: Robert Martin

Publication number: 20050150326Abstract: A swivel gearbox system having multiple drivetrain outputs is disclosed. The system comprises a swivel gearbox and an angled divider gearbox where the power input and divided power output shafts are not in the same plane. The swivel gearbox is a right angle gearbox to permit power input to the divider through a 360 degree range. The output shaft of the swivel gearbox functions as the input shaft of the angled, divider gearbox. The input shaft for the swivel gearbox and the multiple divided output shafts for the divider gearbox are positioned relative to one another in parallel, offset planes, shared shaft between the swivel gearbox and the angled, divider gearbox is preferably positioned in a plane perpendicular to the other input and output shafts. In another embodiment, an angled divider gearbox is provided.Type: ApplicationFiled: January 14, 2004Publication date: July 14, 2005Inventor: Jeffrey Daniel
