20090050824 | METHOD OF FABRICATING A STRUCTURE FROM DIAMOND MATERIAL OR DIAMOND-LIKE CARBON MATERIAL - A method of fabricating a structure from diamond material or diamond-like carbon material, and a structure according to the method, the method comprising the steps of imposing a structural transformation on the crystallographic structure of the material in a first region located at a first depth below a surface of the material; imposing a structural transformation on the crystallographic structure of the material in a second region located at a second depth below the surface of the material and above of the first region, the second depth being selected so that the first region is separated from the second region by a third region; and removing at least a portion of the material of the first and second regions; wherein the structural transformations are imposed so that the crystallographic structure of the third region is largely unaffected and the third region has opposite surface portions from which material of the first and second regions has been removed. | 02-26-2009 |

20100013696 | SYSTEM AND METHOD OF ORBITAL ANGULAR MOMENTUM (OAM) DIVERSE SIGNAL PROCESSING USING CLASSICAL BEAMS - The present invention describes a system and method of OAM diverse signal processing using classical beams for applications in which OAM signal character is controlled such as optical tagging and applications in which OAM signal character is not controlled such as clutter mitigation and interference cancellation for target detection, identification etc. This is accomplished by transmitting a source beam having a prescribed state with one or more non-zero OAM components, reflecting the beam off a ‘tagged’ or ‘untagged’ target and receiving the return beam in the direct return path to measure the one or more OAM components to identify the target. OAM processing provides additional degrees of processing freedom to greatly enhance the processing capabilities to detect and identify both ‘tagged’ and ‘untagged’ targets. | 01-21-2010 |

20130212032 | SKILL COMPETENCY SEARCH AND MANAGEMENT - A method, system, server processing system, and computer program product for conducting a skills competency search and/or managing skills acquisition for a user. In one aspect, the method includes, in a server processing system, steps of: receiving, from a client processing system in data communication with the server processing system, skills competency data indicative a user's competency for a set of skills; storing the skills competency data in a data store; receiving a skills acquisition notice indicative of a skills acquisition task completed by the user; obtaining skills acquisition data based upon the skills acquisition task; updating the skills competency data for the user according to the skills acquisition data; and generating a report indicative of the user's competency for the set of skills. | 08-15-2013 |
