TL;DR: In this article, an acoustic tracking system designed to allow scientists and fishermen to follow dolphins and whales without harming or harassing them is presented, which utilizes six flow shielded hydrophones mounted on the bottom of a vessel in two arrays of three hydrophones in each array.
Abstract: An acoustic tracking system designed to allow scientists and fishermen to follow dolphins and whales without harming or harassing them. The system utilizes six flow shielded hydrophones mounted on the bottom of a vessel in two arrays of three hydrophones in each array. Acoustic signals of interest (dolphin calls) which strike the hydrophone piezo-electric elements are transmitted to a receiver-display device which determines and displays both the bearing to the signal of interest and the relative range from the vessel to that signal. The receiver-display device utilizes digital microprocessors to determine the difference in signal arrival time of an incoming signal at pairs of hydrophones. The resulting computed bearing to the dolphin call is displayed as a lighted indicator on an electronic heading display. In addition, the digital microprocessors compare the received sound pressure level of incoming signals of interest and display the relative range as a series of lighted LED's on the electronic heading indicator.
TL;DR: A flight instrument displays azimuth information in combination with horizon information and other optional information such as altitude and/or airspeed, such as vertical speed and vertical axis information as discussed by the authors.
Abstract: A flight instrument displays azimuth information in combination with horizon information and other optional information such as altitude and/or airspeed. Azimuth information is displayed using an elliptical pattern placed below a horizon line displaying horizon information. The horizon information may be based on gyro enhanced vertical speed and/or vertical axis information. The elliptical pattern may be representative of a horizontal circular heading indicator viewed from above and behind the circular indicator. In one embodiment, the elliptical azimuth pattern moves in response to movement of the horizon line to maintain position below the horizon line. Airspeed and/or altitude information may be displayed at the sides of the screen area using a circular arc display pattern.
TL;DR: In this paper, an apparatus for compensating a magnetic heading indicated by a vehicle's magnetic compass so that the magnetic heading corresponds to a true heading as indicated by signals received in the vehicle from the Global Positioning System was presented.
Abstract: An apparatus for compensating a magnetic heading as indicated by a vehicle's magnetic compass so that the magnetic heading corresponds to a true heading as indicated by signals received in the vehicle from the Global Positioning System. The apparatus includes a computer for calculating compensation factors from successive positions occupied by the vehicle as it travels.
TL;DR: In this paper, the pilot of an aircraft with combined inflight attitude, heading, altitude, and horizontal situation information was provided by using two or three devices providing separate displays, and the preferred embodiment of this invention combines a commonly used and commercially available flight director-type device for providing a display in combination with a miniature aircraft supported for angular displacement from a vertical orientation to indicate heading error, or heading offset, and an extended course deviation indicator bar which projects into juxtaposition with the miniature aircraft to provide a true picture of the aircraft's horizontal situation relative to a selected VOR,
Abstract: A display device particularly suited for providing the pilot of an aircraft with combined inflight attitude, heading, altitude, and horizontal situation information previously available only by using two or three devices providing separate displays. The preferred embodiment of this invention combines a commonly used and commercially available flight director-type device for providing a display in combination with a miniature aircraft supported for angular displacement from a vertical orientation to indicate heading error, or heading offset, and an extended course deviation indicator bar which projects into juxtaposition with the miniature aircraft for providing a true picture of the aircraft's horizontal situation relative to a selected VOR, ILS, or MLS course.
TL;DR: In this article, the authors present a system for determining the final heading of a turning vehicle, such as a rotorcraft, using an algorithm that calculates an advance prediction of a final heading that will be achieved after control input is terminated.
Abstract: Systems and methods are provided for determining a final heading of a turning vehicle, such as a rotorcraft. The system may include an algorithm that calculates an advance prediction of a final heading that will be achieved after control input is terminated. The system may also include a device, such as a display, for conveying predicted final heading information to an aircraft controller, such as a pilot.
