Patent number: 7443334Abstract: A collision alerting and avoidance system for use in an aerial vehicle is presented herein. The system comprises a one low profile antenna array disposed on the aerial vehicle. A transmitter/receiver probe is coupled to the antenna array. The transmitter/receiver probe is configured to transmit electromagnetic waves and to receive an echo signal reflected from a threat obstacle. At least one transmitter/receiver module is coupled to the transmitter/receiver probe. The transmitter/receiver module is configured to produce electromagnetic waves for transmission and to receive the echo signal. A processor coupled to the plurality of transmitter/receiver modules controls the transmission of electromagnetic waves from the antenna array and processes the echo signal to provide an output signal containing information regarding the obstacle.Type: GrantFiled: September 10, 2007Date of Patent: October 28, 2008Inventors: Frank L. Rees, William B. Cotton

Publication number: 20080239877Abstract: A method of detecting hazardous conditions to aircraft is disclosed. The hazardous conditions produce sound waves in the atmosphere. The method comprises directing a first laser beam from a first laser acoustic sensor to a mating first reflector; directing a second laser beam from a second laser acoustic sensor to a mating second reflector; and directing a third laser beam from a third laser acoustic sensor to a mating third reflector. The method further comprises aligning the first laser acoustic sensor to project a first beam pattern, the second laser acoustic sensor to project a second beam pattern, and the third laser acoustic sensor to project a third beam pattern. The method further comprises measuring an effect of the sound waves on the first beam pattern, the second beam pattern, and the third beam pattern. The effect is an indicator of the hazardous conditions.Type: ApplicationFiled: April 6, 2006Publication date: October 2, 2008Applicant: Flight Safety Technologies, IncInventor: Frank L. Rees

Patent number: 7307579Abstract: A collision alerting and avoidance system for use in an aerial vehicle is presented herein. The system comprises a one low profile antenna array disposed on the aerial vehicle. The array includes a plurality of horns; a polar horn, 45-degree horns, and equatorial horns. A transmitter/receiver probe is coupled to each horn. The transmitter/receiver probes are configured to transmit electromagnetic waves and to receive an echo signal reflected from a threat obstacle. A plurality of transmitter/receiver modules are coupled to each of the transmitter/receiver probes. The transmitter/receiver modules are configured to produce electromagnetic waves for transmission and to receive the echo signal. A processor coupled to the plurality of transmitter/receiver modules controls the transmission of electromagnetic waves from the horns and processes the echo signal to provide an output signal containing information regarding the obstacle.Type: GrantFiled: November 2, 2005Date of Patent: December 11, 2007Assignee: Flight Safety Technologies, Inc.Inventors: Frank L. Rees, William B. Cotton

Publication number: 20040174770Abstract: The Gauss-Rees waveform has many applications including use in a method for identifying an object, the method including the steps of: directing a primary acoustic waveform at the object to produce a nonlinear acoustic effect; receiving a secondary wavelet produced by the nonlinear effect; and processing the received secondary wavelet in identifying the object. The object is identified by composition, image, and preferably both. The object can be concealed in a container, underground, under water, or otherwise.Type: ApplicationFiled: November 25, 2003Publication date: September 9, 2004Inventor: Frank L. Rees

Patent number: 6211808Abstract: A collision avoidance system mountable on an aircraft for providing to the pilot of that aircraft an early warning of the presence of another nearby threat aircraft within the surrounding air space. The system operates autonomously from that aircraft and does not require the presence of any matched system on board the threat aircraft. The system includes an omni-directional L-band microwave antenna formed by a dielectric sphere cut into eight equal “orange wedge” sectors covering eight distinct beam patterns. Eight L-band microwave signals are transmitted simultaneously from all eight dielectric sectors to provide a sphere of detection around the aircraft. The sectors also act as receivers for detecting a microwave signal reflected back from the threat aircraft, and indicating means provides information to the pilot regarding the direction, closeness and rate of closure of the threat aircraft.Type: GrantFiled: February 23, 1999Date of Patent: April 3, 2001Assignee: Flight Safety Technologies Inc.Inventor: Frank L.
