Patent number: 11257379Abstract: An embodiment of a communication management unit (CMU) includes emulator and data-mining circuits. The emulator circuit is configured to generate a data request having a same format as a data request from a vehicle communications center, to send the data request to a subsystem disposed on a vehicle, and to receive data sent by the subsystem in response to the data request. The data-mining circuit is configured to provide at least some of the received data to a determining circuit configured to determine information in response to the provided data. For example, such a CMU can request flight-plan data from a flight management subsystem (FMS) by sending, to the FMS, an emulated data-request message having the same format as a data-request message from a ground-based aircraft operations center. That is, the CMU can “fool” the FMS into “thinking” that the data-request message originated from the ground-based aircraft operations center.Type: GrantFiled: March 29, 2019Date of Patent: February 22, 2022Assignee: Honeywell International Inc.Inventors: Raghu Shamasundar, Thomas D.

Patent number: 11257388Abstract: An obstruction detection and warning system includes a plurality of edge light emitters, and a processing system. The edge light emitters are mounted on a structure that has a width and a height. Each edge light emitter is operable to emit a light beam at an angular rate, and that is encoded with data that indicates its position and its height. The processing system receives the light beam emitted from each edge light emitter and decodes the encoded data from the received light beam to determine the width and height of the structure, and to determine a distance from an aircraft to the structure. The processor also compares an active trajectory and current altitude of the aircraft to the width and height of the structure and the distance to the structure and, based on the comparison, generates and supplies situational cues to an operator of the aircraft.Type: GrantFiled: October 30, 2019Date of Patent: February 22, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Raghu Shamasundar, Prashanth Thirumalaivenjamur, Umesh Hosamani, Arivazhagan V, Akshay Sankeshwari
