Publication number: 20240117495Abstract: Cold thermal chemical vapor deposition coatings, articles, and processes are disclosed. Specifically, a cold thermal chemical vapor deposition process includes positioning an article, heating a precursor gas to at least a decomposition temperature of the precursor gas to produce a deposition gas, introducing the deposition gas to a coating vessel, and depositing a coating from the deposition gas onto the article within the coating vessel. The article remains at a temperature below the decomposition temperature throughout the introducing and depositing of the deposition gas. The coating on the article has a gradient formed by the depositing of the coating having no flow for a period of time. The coated article includes a thermally-sensitive substrate (the thermally-sensitive substrate capable of being modified by a temperature of 300 degrees Celsius) and a coating the thermally-sensitive substrate.Type: ApplicationFiled: October 13, 2020Publication date: April 11, 2024Inventors: Geoffrey K. WHITE, Nicholas P. DESKEVICH, James B. MATTZELA, Gary A. BARONE, David A. SMITH, Pierre A. LECLAIR, Min YUAN, Jesse BISCHOF

Publication number: 20180227073Abstract: A technique for adaptively disrupting UAVs detects a target UAV using a camera, monitors the target UAV's communications using a directional antenna aligned with the camera, and attempts to communicate with the target UAV to request that it land, fly away, or return to launch. With the camera trained on the UAV, the directional antenna detects down-link signals from the UAV, which the UAV may employ to communicate with a ground-based controller. Control circuitry analyzes the down-link signals and generates a disrupting signal based thereon. The disrupting signal shares characteristics with the down-link signal, such as its protocol, bit rate, and/or packet length. The directional antenna transmits the disrupting signal back toward the UAV to affect the UAV's flight.Type: ApplicationFiled: February 3, 2017Publication date: August 9, 2018Inventors: Brian Adam Hetsko, John Bernard Kuhl, Robert Johns, David Barone
