Publication number: 20260188130Abstract: In an approach to detecting stationary objects in a traffic alert and collision avoidance system. The method includes supplying an aircraft with a collision avoidance system (CAS) wherein the CAS provides a display for stationary object detection; providing a stationary object with a transponder where the CAS interrogates the stationary object transponder and determines a height and distance of the stationary object relative to the aircraft; wherein the CAS determines a range, bearing and relative altitude of the aircraft relative to the stationary object and: issues either a visual or audible alert; and/or in the case of the stationary object having a lighting system, the CAS provides instructions to the lighting system to increase in lighting intensity or enter a strobe mode of operation.Type: ApplicationFiled: December 16, 2025Publication date: July 2, 2026Inventor: Peter Mark LEE

Publication number: 20240210294Abstract: The present invention is directed at a method to evaluate the wear depth of non-metallic parts. In particular, non-metallic parts formed of polymeric material with selected amounts of metallic particles through the part thickness. Upon wear of the polymeric material the metallic particles are released which can be detected by inductively coupled plasma atomic emission spectroscopy.Type: ApplicationFiled: December 27, 2023Publication date: June 27, 2024Inventors: Lake SPEED, JR., Peter Mark LEE

Publication number: 20240093351Abstract: A variable hardness nanocomposite coating and method for its production. The variable hardness nanocomposite coating can be applied as a single layer on metallic engine components that require a break-in to achieve physical mating of interacting surfaces thereby reducing friction and optimizing engine performance. The single layer nanocomposite coating has a relatively higher carbon content and lower hardness at the surface region and a relatively lower carbon content and relatively higher hardness region as one proceeds towards a surface of the metal component being coated.Type: ApplicationFiled: September 19, 2023Publication date: March 21, 2024Inventors: Jianliang LIN, Peter Mark LEE, Lake SPEED, JR.

Patent number: 10662766Abstract: A dynamic testing system for sealing devices includes a shaft that is reciprocated in a bore through a body. The shaft includes a first seal assembly and a second seal assembly disposed a distance apart on the shaft. When the shaft is inserted into the bore, the first seal assembly and the second seal assembly form a fluid-tight seal between the external surface of the shaft and the internal surface of the bore—this forms a fluid-tight cavity between the seal assemblies. Sealing devices in each of the first seal assembly and the second seal assembly experience chemical attack and mechanical wear. One or more axial force measurement sensors measure the force applied by a prime mover to reciprocate the shaft within the bore. Data acquisition circuitry collects the force information and generates a graphical output that plots friction force against reciprocating cycle count.Type: GrantFiled: June 30, 2017Date of Patent: May 26, 2020Assignee: SOUTHWEST RESEARCH INSTITUTEInventors: Nigil Satish Jeyashekar, Peter Mark Lee

Patent number: 10316970Abstract: A Ti—Si—C—N coating for a piston ring and a method forming such coating, wherein the deposited coating exhibits a thickness in the range of 10.0 micrometers to 20.0 micrometers and exhibits a coefficient of friction of less than 0.15 and a wear rate of less than 10×10?6 mm3/N/m. The coefficient of friction being measured on a Plint TE77 and the wear rate being measured against an alumina ball of 0.25 inches in diameter at a load of 1 N at 100 rpm in a dry environment. The deposited Ti—Si—C—N coating includes nanocrystalline phases in an amorphous matrix.Type: GrantFiled: November 22, 2016Date of Patent: June 11, 2019Assignee: Southwest Research InstituteInventors: Jianliang Lin, Ronghua Wei, Peter Mark Lee, Daniel Christopher Bitsis, Jr.

Patent number: 9689776Abstract: An apparatus including a piston bore, exhibiting a longitudinal axis, and a piston, including a piston head and a piston shaft. The piston being axially displace-able within the piston bore along the longitudinal axis. The piston bore and a first surface of the piston head form a first working volume and displacement of the piston alters the first working volume. The apparatus also includes a first plurality of injectors coupled to the first working volume and a first common rail. The first plurality of injectors are configured to inject a hydraulic fluid from the common rail into the first working volume. The first common rail is configured to store the hydraulic fluid at an elevated pressure of 1,000 bar or greater. The apparatus includes a flow path between the first working volume and a reservoir for the hydraulic fluid.Type: GrantFiled: November 6, 2014Date of Patent: June 27, 2017Assignee: Southwest Research InstituteInventors: Riccardo Meldolesi, Peter Mark Lee
