Publication number: 20220231397Abstract: A mechanical means for deploying one of two or more feed sources within a test range is presented. The feed source selected for testing is properly positioned for use within the range by rotating one of two or more arms to an upright and locked position. An arm may further include a rotatable antenna wheel with two or more feed sources thereon whereby a selected feed source is rotated into position via the antenna wheel. The antenna wheel includes a center body, feed sources attached to the center body and aligned along a rotational plane, and a shroud disposed about the center body and feed sources. The antenna wheel may include a cooling system for managing heat generated by the feed sources and electronics therefore. In preferred embodiments, the feed source changer is mounted within the range so that a selected feed source communicates an emitted beam onto a reflector which is redirected as a reflected beam toward a device under test.Type: ApplicationFiled: April 5, 2022Publication date: July 21, 2022Inventors: William Campbell, Thomas McKeown, Per Iversen, Thomas D. Kauffman, Zachary J. Pelli, Thomas P. O'Donnell

Patent number: 8821075Abstract: A yield support prop for a mine includes a first metal tube extending from the mine floor having a first portion having a first outside diameter and a second portion having a second outside diameter. The prop includes a second metal tube that is disposed about the first portion and extends toward the mine roof, when the second tube receives a load from the mine roof, the second portion deforms the second tube and expands the second tube creating resistance against the load from the mine roof. A method for supporting a mine roof. A method for building a yieldable mine prop.Type: GrantFiled: October 26, 2011Date of Patent: September 2, 2014Assignee: Strata Products Worldwide LLCInventors: Clifford A. McCartney, Thomas P. O'Donnell

Patent number: 8257209Abstract: A versatile, variable gear ratio mechanical transmission system is providing having similar first and second spaced Disc Subsystems connected by a belt or chain. Each subsystem of which comprises three primary components: (1) a Shift Actuation Structure located at one outermost side; (2) a Receiving Disc located at the opposite side; and, (3) a Retention Disc sandwiched between. The Retention and Receiving Discs accommodate concentric rings of proportionally spaced holes in which corresponding smooth, contoured or toothed Headed Pins are maintained, engaged, or retracted. When the pins are engaged, they span the slot between the Receiving Disc and Retention Disc and interface with the conveyance transferring load from Driving Disc Subassembly to the Driven Disc Subassembly.Type: GrantFiled: April 11, 2011Date of Patent: September 4, 2012Inventors: Joseph C. Lane, Robert S. Siegwart, Thomas P. O'Donnell

Patent number: 8126232Abstract: A method for segmenting tubular structures in digital medical images includes extracting a subregion from a 3-dimensional (3D) digital medical image volume containing a vessel of interest, identifying potential vessel centerpoints for each voxel in the subregion by attaching to each voxel a tip of a 3D cone that is oriented in the direction of the voxel's image gradient and having each voxel within the cone vote for those voxels most likely to belong to a vessel centerline, selecting candidates for a second vote image that are both popular according to a first vote image, as well as being consistently voted upon by a radius image, reconfiguring the subregion as a graph where each voxel is represented by a node that is connected to 26 nearest neighbors by n-link edges, and applying a min-cut algorithm to segment the vessel within the subregion.Type: GrantFiled: February 24, 2009Date of Patent: February 28, 2012Assignee: Siemens AktiengesellschaftInventors: Engin Dikici, Thomas P.
