Publication number: 20240085221Abstract: A system and method for measuring an amount of backlash in an actuator assembly that includes a housing assembly, an actuator, a drive source, an actuator position sensor, a drive source position sensor, and a controller. The controller is in operable communication with the drive source, the actuator position sensor, and the drive source position sensor, and is configured to selectively implement a built-in test that determines the amount of backlash in the actuator assembly.Type: ApplicationFiled: September 14, 2022Publication date: March 14, 2024Applicant: HONEYWELL INTERNATIONAL INC.Inventors: David Podola, Michal Nozka, Radek Hedl, Albert Mikan

Patent number: 11319883Abstract: A system and method for diagnosing load compressor health state for an auxiliary power unit that includes a power compressor, a combustor, a power turbine, and a load compressor is provided. The auxiliary power unit is operated and bleed air is discharged from the load compressor at a bleed air pressure. Using a pressure sensor, the bleed air pressure discharged from the load compressor is sensed and supplied to a processor. In the processor, power compressor health state is diagnosed based solely on the sensed bleed air pressure.Type: GrantFiled: February 20, 2019Date of Patent: May 3, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Lukas Vesely, Lukas Palaj, Jan Neuzil, Radek Hedl

Patent number: 10677765Abstract: Methods and systems structural health monitoring system for a cyclically loaded structure are provided. The system includes a processor and a memory, and is configured to, in accordance with a data acquisition pattern: acquire raw sensed data from each of the N sensors; convert the raw sensed data into a data packet; store the data packet as a first data packet; acquire raw sensed data from each of the N sensors a second time and store the data packet as a second data packet; identify a scalar deviation between the first data packet and the second data packet; and transmit anomaly information to an external maintenance reasoner when the scalar deviation is determined to exceed a threshold. The data acquisition pattern incorporates a customer specific arrangement of a plurality of piezoelectric (PZT) sensors and sampling the sensors at predetermined angular locations on a circle of rotation associated with the structure.Type: GrantFiled: December 12, 2017Date of Patent: June 9, 2020Assignee: Honeywell International Inc.Inventors: Peter Raso, Cenek Sandera, Radek Hedl

Publication number: 20150308920Abstract: A system and method for detecting damage growth in a structure includes sensing, with a sensor that is coupled to the structure, a physical quantity reflecting damage growth, to thereby generate and supply a sensor signal. Features are extracted from the sensor signal to thereby generate a current feature vector. The current feature vector is assigned to either a previously created cluster or to a new cluster. A stability measure is calculated based on clusters to which the current feature vector and a predetermined number of previous feature vectors are assigned. An alarm is selectively generated based on the calculated stability measure.Type: ApplicationFiled: April 24, 2014Publication date: October 29, 2015Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Cenek Sandera, Radek Hedl

Patent number: 8831895Abstract: A system and method for detecting and evaluating structural defects are provided. Baseline data representative of sensed ultrasonic waves that were transmitting into a structure with no defects are stored. Ultrasonic waves are transmitted into the structure from a plurality of actuators that are coupled to the structure. The ultrasonic waves that are transmitted into the structure from the plurality of actuators are sensed, with a plurality of sensors that are coupled to the structure and spaced apart from the actuators, to thereby generate and supply sensor data. Signal difference coefficients are calculated from the baseline data and the sensor data. The calculated signal difference coefficients are spatially mapped to detect one or more structural defects in the structure.Type: GrantFiled: June 27, 2011Date of Patent: September 9, 2014Assignee: Honeywell International Inc.Inventors: Radek Hedl, Jindrich Finda, Karel Adamek

Patent number: 8429974Abstract: Methods and systems for detecting features in thin-wall structures are provided. A plurality of ultrasonic waves are generated within a thin-wall structure. At least one echo from the plurality of ultrasonic waves within the thin-wall structure is detected. The at least one echo is processed to determine a position of at least one feature in the thin-wall structure based on Embedded Ultrasonic Structure Radar (EUSR) beamforming performed in the frequency domain.Type: GrantFiled: May 24, 2010Date of Patent: April 30, 2013Assignee: Honeywell International Inc.Inventors: Radek Hedl, Girija Parthasarathy
