Patent number: 10723479Abstract: In one example, a method includes receiving, over an aircraft data communications bus, a plurality of non-pneumatic inputs corresponding to aircraft operational parameters. The method further includes processing the plurality of non-pneumatic inputs through an artificial intelligence network to generate an air data output value, and outputting the air data output value to a consuming system for use when a pneumatic-based air data output value is determined to be unreliable.Type: GrantFiled: February 15, 2018Date of Patent: July 28, 2020Assignee: Rosemount Aerospace Inc.Inventors: Kaare Josef Anderson, Brian Daniel Matheis, Derrick D.

Patent number: 6615657Abstract: A built-in test system for an ultrasonic liquid level sensor that includes a transducer assembly having an ultrasonic transducer, and a switch that will be actuated when the ultrasonic transducer is in intimate contact with a surface of a tank in which level is to be determined. Once the switch is actuated to indicate that the ultrasonic transducer is properly coupled to the surface, a test sequence is initiated to determine that the level of ultrasonic transmissions are above a certain desired threshold for a selected period of time, and after which the circuit looks for echoes to determine the depth of the liquid in the tank. Thereafter, the test sequence is repeated for each cycle of level sensing.Type: GrantFiled: January 4, 2001Date of Patent: September 9, 2003Assignee: Rosemount Aerospace, Inc.Inventors: Derrick D. Hongerholt, Eric D. Haugen, Charles G. Huss, Greg A. Seidel

Patent number: 6568270Abstract: A contaminant sensor is provided which has an ultrasonic guided wave transducer that is bonded to a wall in which the ultrasonic energy is transmitted. A detector reflector is provided at a selected distance from the transducer, which will reflect signals that are affected or changed by contaminants collecting on an exposed surface of the wall. A self test reflector is positioned closely adjacent to the transducer and provides a reflected signal that is substantially unaffected by contaminants on the exposed surface of the wall, but which reflects signals only when the transducer assembly is functioning properly, and is properly bonded to the wall. The signal that is reflected by the self test reflector changes when the bond loosens. The receiver is activated right after transmission ceases to determine if the transmitter is operating.Type: GrantFiled: March 13, 2001Date of Patent: May 27, 2003Assignee: Rosemount Aerospace Inc.Inventor: Derrick D. Hongerholt

Patent number: 6536276Abstract: A liquid level sensor used for determining liquid levels in a sealed container includes a heat source bonded to the container, a first temperature sensor mounted on the container adjacent the heat source, and a second temperature sensor mounted on the container spaced from the heat source. The temperatures at the first and second temperature sensors are sensed while the heat source is operating, and the differential in the temperatures is measured and used to control power to the heater. Changes in the differential in temperature between the first and second temperature sensors indicates when the heat conductivity between the first and second temperature sensors changes, due to presence or absence of a liquid in the container at the level of the temperature sensors.Type: GrantFiled: February 27, 2001Date of Patent: March 25, 2003Assignee: Rosemont Aerospace Inc.Inventors: Charles G. Huss, Mark R. Koosmann, Derrick D. Hongerholt, Eric D. Haugen, Greg A. Seidel, Stephen R. Meyer, Gary A. Willms

Patent number: 6412344Abstract: A sensor for measuring the height of fluid in a vessel, the sensor including a mounting base shaped to be coupled to an exterior surface of a vessel. The sensor further includes a transducer having a pulse source for sending pulses into the vessel and an echo detector for detecting echoes of pulses emitted by the pulse source. The sensor further has a dry couplant located between the transducer and the mounting base, and a processor connected to the transducer for calculating the height of fluid in the vessel based at least in part upon the time elapsed between the pulses sent by the transducer and echoes detected by the echo detector.Type: GrantFiled: November 15, 1999Date of Patent: July 2, 2002Assignee: Rosemount Aerospace Inc.Inventors: Jeffrey P.

Patent number: 6378377Abstract: An ultrasonic ice detector that can be mounted directly to the skin of an aircraft includes a transducer that is coupled to the interior surface of the skin, and transmits acoustic vibrational energy through the skin. A reflector bar having a reflector surface is mounted on the interior surface of the skin at a location spaced from the transducer and is effective to reflect acoustic energy back to the transducer. The reflector bar is raised from the interior surface and preferably has a width equal to the width of the acoustic wave that is generated by the transducer at the reflector location. The transducer and reflector are non-intrusive and do not alter the aircraft skin structural integrity. The arrangement provides an accurate, responsive sensor for determining presence of ice or other contaminants on the exterior surface of the skin.Type: GrantFiled: April 23, 1999Date of Patent: April 30, 2002Assignee: Rosemount Aerospace Inc.Inventors: Timothy J. Matuseski, Derrick D. Hongerholt, Krishna M. Rajana
