Patent number: 10685572Abstract: A transponder system that is adapted to be positioned in an aircraft includes a transponder that is adapted to transmit information pertaining to the aircraft in which the transponder is positioned includes at least one receiver that is adapted to receive information including information pertaining to another aircraft. The receiver(s) is adapted to receive different types of data on multiple different frequencies. A display, which may be integral with the system housing or remotely mounted, is adapted to display (i) information received by said receiver and/or (ii) information to guide user input selection of information transmitted by said transponder. The housing houses the transponder, the receiver and, in one embodiment, the display. The existing transponder in the aircraft can be removed thereby leaving an opening in the aircraft and the transponder installed in the opening.Type: GrantFiled: February 1, 2016Date of Patent: June 16, 2020Assignee: AVIATION COMMUNICATION & SURVEILLANCE SYSTEMS, LLCInventors: Blake R.

Patent number: 10324178Abstract: An Automatic Dependent Surveillance-Broadcast (ADS-B) system, and method of harmonizing a transponder Squawk code and an ADS-B system, ensures that a Squawk code broadcast by the ADS-B system matches the transponder Squawk code. The transponder Squawk code is transmitted from a transponder positioned onboard an aircraft, and the transmitted transponder Squawk code is received by a device positioned onboard the aircraft in which the transponder is installed. The ADS-B system is updated with the received transmitter squawk code. The squawk code is transmitted using the ADS-B system.Type: GrantFiled: December 22, 2015Date of Patent: June 18, 2019Assignee: L3 AVIATION PRODUCTS, INC.Inventors: Gary S. Watson, Lee R.

Publication number: 20190076056Abstract: An improved apparatus and method for capturing and analyzing the end-tidal portion of an exhalation. The CO2 level of air drawn into the system (10) is monitored to distinguish inhalation and exhalation of breath. Upon detection of a decrease in the CO2 level in the air drawn into the system (10), indicating a transition between exhalation and inhalation a pair of flow selector valves (26, 28) are operated to capture the end-tidal volume of air drawn into the system (10) immediately prior to the detection of the decrease in the CO2 level. Incoming air is diverted around the captured volume of air, and the CO2 levels are continually monitored to ensure that the captured volume of air corresponds to the end-tidal portion of an exhalation. Once the captured volume of air is positively identified as the end-tidal portion of an exhalation, the captured volume is routed through a gas analyzer (44) for analysis of one or more predetermined gas levels.Type: ApplicationFiled: April 6, 2018Publication date: March 14, 2019Inventors: Lee R. CARLSON, Edward A. MCCLATCHIE, Joe MARTINOSKY, Ralph WALDEN, Elvir CAUSEVIC

Patent number: 5376163Abstract: A method and system are described for preventing flooding of a gas analyzer of the type wherein a pump conveys gas to be analyzed to a sample cell and a filter separates water from the gas flowing to the pump. The presence of excess liquid in the system is sensed by a pressure transducer which decouples the output of the pump from the sample cell and feeds it back to the filter. This results in an increase in pressure in the filter to prevent excess liquid from flooding the gas analyzer. The pressure is so held until the excess liquid passes from the filter system, after which the system returns to normal operation.Type: GrantFiled: May 18, 1993Date of Patent: December 27, 1994Assignee: Andros IncorporatedInventors: Lee R.

Patent number: 4685109Abstract: A plasma tube for a gas laser includes a series of heat webs and insulative spacers between the heat webs, with tungsten bore insert members supported by the heat webs and having aligned apertures defining a laser discharge path. To produce the plasma tube, the heat webs, spacers and other connected components are assembled in a vertical stack outside the ceramic tube of the laser, with a stacking gauge which helps assure that the heat webs are correctly spaced apart within close tolerances. The heat webs lie adjacent to annular metallized areas on the inside surface of the ceramic tube when the assembly is inserted into the tube, which is precision-formed ceramic tubing. The tube assembly is heated in vertical orientation to expand the heat webs diametrically so that they engage outwardly against and are brazed to the metallized areas of the ceramic tube.Type: GrantFiled: September 11, 1986Date of Patent: August 4, 1987Assignee: Spectra-Physics, Inc.Inventors: Lee R. Carlson, Denes A. Hegedus, Steven M. Jarrett, Michael F. Miller, Martin E. Riley, David L. Wright
