Patent number: 12087092Abstract: An aircraft-based pilot safety system (PSS) includes cameras or other gaze sensors fixed at an aircraft pilot and configured to capture an image stream focused on the pilot's eyes. The gaze sensors continually assess the gaze direction of the pilot (e.g., toward a display, instrument panel, and/or indicator within the cockpit that the pilot is currently looking at or focusing on) and thereby can establish when the pilot is executing a scan pattern and if that scan pattern is nominal for the current flight context by comparing the scan pattern to context-specific reference scan patterns. If, for example, the pilot's gaze deviates from where it should be (e.g., as determined by the current flight segment) or the current scan pattern is interrupted, the system may prompt the pilot to redirect their gaze or resume the scan pattern.Type: GrantFiled: May 2, 2022Date of Patent: September 10, 2024Assignee: Rockwell Collins, Inc.Inventors: Christopher L George, Arjun Harsha Rao, Timothy J. Wittkop, Wade T. Johnson, Peggy Wu, Michael P. Matessa

Patent number: 12042289Abstract: A computerized system for recognizing the need for cognitive tests due to a physiological event and administering such tests includes a plurality of biometric monitoring devices and a pilot input device. When a physiological event is identified, the system selects an appropriate battery of tests and automatically administers those tests. The system offers the opportunity to automate pilot evaluation for single pilot operations, and to reduce the burden on a co-pilot. The cognitive tests may be specific to the physiological event, and may be compared to a pilot-specific profile when evaluating the results.Type: GrantFiled: May 20, 2022Date of Patent: July 23, 2024Assignee: Rockwell Collins, Inc.Inventors: Michael P.

Patent number: 11887486Abstract: A context driven alerting system and method is described in accordance with one or more embodiments of the present disclosure. The alerting system and method may consider a pilot's physiological, psychological, and behavioral state during a given mission context. The system may include biometric information which is fused with a context of the flight. The context may be based on one or more of a mission profile data or an aircraft state data. The fused data may be time synchronized and provided to an alerting algorithm. The alerting algorithm may then provide an alert to the pilot which includes a priority, intensity, frequency, or modality determined based on the fused information.Type: GrantFiled: May 13, 2022Date of Patent: January 30, 2024Assignee: Rockwell Collins, Inc.Inventors: Arjun Harsha Rao, Peggy Wu, Christopher L George, Timothy J.

Publication number: 20240016394Abstract: An aircraft system includes an aircraft control having embedded biometric sensors. The biometric sensors record pilot physiological data at various phases of flight for analysis and pilot monitoring. The biometric data may be recorded and correlated to flight phases to establish a base-line profile for an individual pilot or an individual flight phase for later comparison and monitoring. Certain biometric data may be used as a secondary characteristic to confirm the identity of a pilot, or to verify that a pilot is currently engaging the aircraft control.Type: ApplicationFiled: May 17, 2022Publication date: January 18, 2024Inventors: Christopher L George, Timothy J.

Publication number: 20220388677Abstract: An operator safety system (OSS) monitors the physiological well-being of an aircraft pilot or vehicle operator, and has engaged and disengaged operational states (the engaged state associated with active monitoring). The OSS includes a smart engage/disengage system incorporating presence sensors (e.g., visual, seat-based) installed in the cockpit or control area of the vehicle. When the presence sensors determine that the pilot/operator is no longer present in their seat but the OSS is still engaged, the OSS prompts the operator to disengage the OSS (e.g., via single-touch display interface or remotely to a mobile device). When the presence sensors determine that the operator is present or seated, but the OSS is disengaged, the OSS prompts the operator to re-engage the OSS.Type: ApplicationFiled: May 2, 2022Publication date: December 8, 2022Inventors: Christopher L.
