Publication number: 20210319636Abstract: A method in an aircraft of using prognostic indicators for aircraft maintenance includes retrieving aircraft health data for a plurality of aircraft components wherein the aircraft health data includes at least one of mechanical systems condition indicator (CI) data, vibration spectrum data, resampled time-domain (RTD) data, and RTD spectrum data. The method includes estimating component health status information for the plurality of aircraft components using a plurality of prognostic modules wherein each prognostic module is configured to generate health status information for at least one of the aircraft components, the health status information includes at least one of a current health indicator and a prognostic indicator. The method also includes storing the component health status information for the aircraft components in a database onboard the aircraft, and causing the display of the health status information for the specific component on an aircraft display.Type: ApplicationFiled: January 22, 2021Publication date: October 14, 2021Inventors: Raj Mohan Bharadwaj, Kyusung Kim, Kwong Wing Au, Paul Frederick Dietrich, Piyush Ranade, Andrew Peter Vechart, Megan Hawley, Abraham Reddy, Craig Schimmel, David Daniel Lilly

Patent number: 10169927Abstract: Methods and systems are provided for presenting information pertaining to the health of one or more mechanical components of a vehicle. One exemplary method involves a client device initiating an ad hoc wireless connection with a monitoring system onboard the vehicle, requesting status information for the vehicle from the monitoring system via the ad hoc wireless connection, and receiving the status information for the vehicle from the monitoring system via the ad hoc wireless connection. The monitoring system generates the status information based at least in part on measurement data obtained from one or more sensor systems during operation of the vehicle and provides the status information in response the request. The client device processes the status information present the one or more graphical representations of the current condition of the one or more mechanical components of the vehicle on the client device.Type: GrantFiled: August 21, 2014Date of Patent: January 1, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: David Daniel Lilly, Charles Kemp

Patent number: 9041594Abstract: An RF beam is used to probe the presence or absence of a rotating blade in a known field of view. Timing of appearance or disappearance or “zero-crossing” of a reflected signal is correlated with timing of the blade movement. Blades which are leading or lagging versus other blades will produce different timing signatures representative of alignment of the blades.Type: GrantFiled: May 24, 2011Date of Patent: May 26, 2015Assignee: Honeywell International Inc.Inventors: Andy Peczalski, David Daniel Lilly, Dinkar Mylaraswamy

Patent number: 7595727Abstract: A system for inspecting a secure enclosure from a remote location to determine whether a secure enclosure door has been opened includes a seal having a base material and an indicator. The base material is bonded across first and second secure enclosure surfaces that must move relative to each other when the secure enclosure door opens. The indicator includes an indicator component that is coupled to the base material to deform in response to a relative movement between the first and second secure enclosure surfaces. The indicator provides a first indication prior to deformation of the indicator component and a second indication after deformation. Indicator components can include an impedance element, a piezoelectric material, volatile memory, a transmitter assembly component or a bar code. A monitor (e.g. RF signal receiver or a bar code reader) receives the indication and determines whether the secure enclosure door has been opened.Type: GrantFiled: May 16, 2003Date of Patent: September 29, 2009Assignee: Information Systems Laboratories, Inc.Inventors: Ramon Lorenzo Grijalva, Mark Allen Herman, David Daniel Lilly
