Publication number: 20250329980Abstract: An optical amplifier system as disclosed includes a gain medium and a pump mechanism configured to amplify first and second optical beams when they pass through the gain medium. The first and second beams, which have the same wavelength, take different paths through the gain medium such that the beams are neither parallel nor coaxial when they exit and/or enter through a first side of the gain medium. A prism having a facet positioned on the first side of the gain medium is in the path of both beams. The facet is orientated to cause total internal refection of the one of the beams within the prism but be transmissive to the other, so that paths of the two beams can be altered relative to one another allowing the beams to be either brought closer together or separated out.Type: ApplicationFiled: May 30, 2023Publication date: October 23, 2025Applicant: Leonardo UK LtdInventors: John BARR, Stephen BEECHER, Elizabeth MCDOUGALL, Dan THORNE

Publication number: 20240103176Abstract: The system includes first and second laser illuminators to illuminate a scene, including a target. The pulses of light emitted from the first laser illuminator having a relatively broad spectral linewidth and a relatively long pulse duration compared with pulses of light from the second laser illuminator. A camera system uses a relatively long gate period for receiving returns from the first laser illuminator to obtain a first image of the scene and to use a relatively short gate period together with ranging information of the target to receive returns from the second laser illuminator to obtain a second image of the target that selectively excludes non-target elements within the scene. The second image is used as a template to selectively remove the non-target elements from the first image.Type: ApplicationFiled: February 2, 2022Publication date: March 28, 2024Applicant: Leonardo UK LtdInventor: John BARR

Patent number: 11925723Abstract: Antimicrobial metal ion coatings and implants including them. In particular, described herein are coatings including an anodic metal (e.g., silver and/or zinc and/or copper) that is co-deposited with a cathodic metal (e.g., palladium, platinum, gold, molybdenum, titanium, iridium, osmium, rhodium, manganese, niobium or rhenium) on a substrate so that the anodic metal is galvanically released as antimicrobial ions when the apparatus is exposed to a bodily fluid. The anodic metal may be at least about 25 percent by volume of the coating, resulting in a network of anodic metal with less than 20% of the anodic metal in the coating fully encapsulated by cathodic metal. The implant may be configured as an implant such as a bone-screw or intramedullary rod-like body configured to receive a treatment cartridge having a coating as described.Type: GrantFiled: June 1, 2021Date of Patent: March 12, 2024Assignee: Silver Bullet Therapeutics, Inc.Inventors: Houdin Dehnad, Paul E.
