Patent CA-2220745-A1 (CA)
Inventor: DRACH WILLIAM C
IPC: H01Q3/32
Filed: 1997-12-01
Abstract: A phase shifter for electrically adjusting the down-tilt of an antenna, based on rotating at least one phase wheel having a specially shaped dielectric.Each phase wheel is rotatably mounted between a stripline and the metallic ground plane of a feed system for an RF signal communicating the RF signal between each element of the antenna and a common terminal. The dielectric distributed on each phase wheel is shaped so that as the phase wheel is turned mechanically, the amount of dielectric directly beneath the stripline and above the metallic ground plane either increases or decreases in some proportion to the amount (angular displacement) the wheel is turned. All the phase wheels used in a system can be arranged, oriented, and tractively coupled so as to rotate in synchrony under the action of a single drive, which may itself be driven by a stepper motor for accurate, fine control. The phase wheels provide for continuous adjustment of the down-tilt of an antenna without having to convert between rotational and linear motion in moving dielectric into or out ofposition between the stripline and metallic ground plane.

Title: Oxide ceramic composite for high temperature environment device, method and system
Inventor: RADFORD KENNETH C
IPC: C04B35/76
Filed: 1996-12-12
Abstract: An oxide ceramic composite suitable for fabricating components of combustion turbines and similar high temperature environments. The composite is fabricated by dispersing metal particles in a fiber preform and infiltrating the fiber preform with sol-gel matrix precursor material. Alternatively, the metal particles are mixed into the sol-gel matrix precursor material and the preform is infiltrated with the mixture.  Later in the fabrication process, the metal particles oxidize and become oxidized metal when the sol-gel matrix precursor material is sintered. The oxidized metal has more volume and mass than the metal particles. As a result, the oxidized metal contributes to increasing the density of the composite so that it is suitable for use in combustion turbines and similar high temperature environments.

Patent CA-2248420-A1 (CA)
Inventor: GLASS CARTER M
IPC: G01S13/90
Filed: 1998-09-25
Abstract: An improved method is provided for phase unwrapping in coherent imaging systems which use two complex images to form an interferogram. In the improved method, the interferogram of phase differences is divided into a relatively large plurality of transform blocks, wherein each transform block comprises a matrix of o x p data samples, with o and p = 2" + 1, and n being an integer greater than 2. Further, adjacent transform blocks are preferably defined to partially overlap. The wrapped phase values of adjacent data samples within each transform block are then compared and if the difference therebetween exceeds a predetermined value, the entire block of data samples may be discarded for further use. Data samples of the retained transform blocks are then unwrapped to obtain phase values via an unweighted, least-squares technique implemented by Fast Fourier Transform.  Using a known height value corresponding with a single data sample, an integration constant can be determined for a corresponding first transform block. Path-following may then be used to determine an integration constant for the other retained transform blocks. The phase values and integration constants may then be employed to determine height values for the interferogram. The disclosed method yields enhanced accuracy with reduced computational burden.
