20080310789 | Method of Changing the Birefringence of an Optical Waveguide by Laser Modification of the Cladding - A method of inducing birefringence in an optical waveguide is disclosed wherein the waveguide cladding is irradiated with energy of a sufficient intensity so as to induce a stress in the optical waveguide so as to cause a multitude of spaced stress induced regions within the cladding of the optical waveguide such that there are 10 to 5000 spaced regions per mm and wherein the stress induced regions are proximate the core greater than 2 microns distance from the core-cladding interface. This waveguide has numerous uses, for example a fiber sensor. | 12-18-2008 |

20090317928 | HIGH TEMPERATURE STABLE FIBER GRATING SENSOR AND METHOD FOR PRODUCING SAME - A method of producing a thermally stable grating allows the grating to be placed in environments where temperatures reach 1000° C. and where the grating is relatively stable and has very low loss from scatter. These gratings have spectral characteristics that allow them to be concatenated so as to form a sensor array. The method requires a step of lowering the characteristic intensity threshold of a waveguide by at least 25%, followed by irradiating the waveguide with femtosecond pulses of light having a sufficient intensity and for a sufficient duration to write the grating so that at least 60% of the grating remains after exposures of at least 10 hours at a temperature of at least 1000° C. Pre-writing a Type I grating before writing a minimal damage Type II grating lowers the characteristic threshold of the waveguide so that a stable low damage type II grating can be written; alternatively providing a hydrogen or deuterium loaded waveguide before writing the grating lowers the characteristic threshold of the waveguide. | 12-24-2009 |

20090211180 | BEARING BRACE APPARATUS - The present invention is directed to a brace apparatus having a core member configured to absorb energy generated by seismic or other forces by undergoing plastic deformation. A buckling restraining assembly is included for maintaining the structural integrity of the brace after the core member has undergone plastic deformation. The buckling restraining assembly includes one or more bearings is located proximal the core member. The bearings are adapted to minimize friction between the core member and the buckling restraining apparatus. An air gap is positioned between the core member and the one or more bearings of the buckling restraining apparatus are adapted to prevent bonding of the core member and buckling restraining assembly. Projections are included in the core member of the brace apparatus to minimize movement of the middle portion of the core member relative to the buckling restraining assembly. | 08-27-2009 |
20120013661 | AUTOMATED BEAM MARKER - A beam marking system is disclosed for marking on beams with a marking device. The beam marking system includes a beam marking device configured to mark on the surface of a beam. A movable arm is coupled to the marking device. The movable arm has at least three movable components that collectively move the beam marking device along or about at least three axes. A controller is in electronic communication with the movable arm and the marking device. The controller controlling the movement of the at least three movable components of the movable arm and controlling the operation of the marking device. In some instances, the beam marking system can automatically mark beams, such as metal beams used in heavy construction projects in a rapid and accurate manner. | 01-19-2012 |

20100004732 | MEDICAL APPLIANCE DELIVERY APPARATUS AND METHOD OF USE - The present invention, in an exemplary embodiment, provides a stent deployment apparatus comprising safety and stent placement and deployment features. An exemplary stent deployment apparatus includes a longitudinally extending outer tubular member and a safety mechanism coupled thereto, wherein the safety mechanism includes a diverted channel. The apparatus also includes a longitudinally extending inner tubular member being longitudinally and axially displaceable relative to the outer tubular member, wherein the inner tubular member further comprises at least one detent along the longitudinal expanse thereof for operative interaction with the diverted channel. The extent of displaceability of the outer tubular member and inner tubular member relative to the other is limited to a predetermined threshold corresponding to engagement of the detent with the diverted channel absent intervention by the user of the device such that the degree of stent deployment is limited absent the user intervention. | 01-07-2010 |

20130055338 | Detecting Addition of a File to a Computer System and Initiating Remote Analysis of the File for Malware - In certain embodiments, a computer system includes a memory unit and a processing unit. The processing unit executes a monitoring module stored on the computer system. The monitoring module monitors the computer system for addition of a file to the computer system and detects an addition of a file to the computer system. The monitoring module accesses policies to determine whether to communicate information associated with the detected addition of the file over a communication network to a remote malware analysis system to initiate a possible malware analysis of the file by the remote malware analysis system. The monitoring module initiates, in response to determining to communicate information associated with the detected addition of the file, communication over the communication network of information associated with the detected addition of the file to the remote malware analysis system, the remote malware analysis system operable to analyze the file for malware. | 02-28-2013 |
