Patent number: 9170316Abstract: Systems and methods for improving bearing availability and accuracy in a traffic collision-avoidance system (TCAS). In an exemplary method, if only a single phase-difference value is received for one of two two-element antennas, a processor determines an expected maximum antenna element phase-difference value for the elements of the two-element antenna that did not receive a phase-difference value for a target signal source; estimates a phase-difference value for the two-element antenna that did not include a phase-difference value, based on the expected maximum antenna element phase-difference value and a previously determined predicted bearing value; and calculates bearing based on the estimated phase-difference value and a phase-difference value received from the other two-element antenna.Type: GrantFiled: October 26, 2012Date of Patent: October 27, 2015Assignee: Honeywell International Inc.Inventors: Ruy C. Brandao, Eduard Shestak, Ian Dougherty

Patent number: 9055201Abstract: An apparatus and method of storing and searching for an image are provided. The apparatus includes: a first signal processor which receives location information about an object detected by a sensor, generates and transmits a camera control signal to a camera based on the location information so that the camera performs a surveillance in a direction according to the camera control signal, and receives from the sensor an alarm signal notifying an intrusion of the object into a preset area; a second signal processor which receives a surveillance image of the intruding object received from the surveillance of the camera; and a control unit which stores the surveillance image in a storage unit.Type: GrantFiled: October 15, 2012Date of Patent: June 9, 2015Assignee: SAMSUNG TECHWIN CO., LTD.Inventor: Ki-Yong Jeon

Patent number: 9041587Abstract: According to one aspect of the present invention, a radar system is provided which accurately measures the surface profile in a wide sector beneath and forward of a helicopter, to aid low level transit and landing in poor visibility. This uses an electronic beam synthesis technique to form multiple beams directed at the area of interest, each measuring the distance to the first reflected signal received by each beam. These distances represent the profile of the ground and any objects on the ground. A processor then compares the measured profile with the ideal ground profile for safe landing. If the deviations from straight and level exceed the specified requirement for safe landing, or if sufficient rotor clearance is not detected, then a warning is given to the operator. A display will show the measured ground profile highlighting the unsafe regions, allowing the operator to seek a safe region to land.Type: GrantFiled: March 19, 2013Date of Patent: May 26, 2015Assignees: Teledyne Australia PTY LTD, Teledyne Technologies IncorporatedInventor: Ian Dennis Longstaff

Patent number: 9024812Abstract: Systems and methods for providing antenna calibration can be used in a variety of applications. A method of calibrating an antenna array for use in a traffic advisory system or traffic alert and collision avoidance system provide a mechanism that renders complex combining circuitry unnecessary in the array. A method can include receiving an unsolicited reply that contains absolute position information of an intruder aircraft. The method can also include determining a bearing of a signal encoding the reply based on a phase relationship of the signals from an antenna array not configured to operate with an internal self-test phase calibration mechanism. The method can further include comparing the bearing based on the phase relationship with a bearing calculated by a comparison of the absolute positions of a host aircraft and the intruder aircraft. The method can additionally include calibrating the antenna array based on the result of the comparison.Type: GrantFiled: April 28, 2011Date of Patent: May 5, 2015Assignee: Aviation Communication & Surveillance Systems LLCInventor: Mark D.
