  • Patent number: 6335905
    Abstract: A sonar depth sounder device and method for processing echo signals, reflected from objects within a body of water, utilizes a processor, a memory, a display, and a keypad connected to the processor. The receiver receives sonar signals indicative of ambient noise in an underwater environment. The processor receives an electrical signal representative of the ambient noise, and calculates a detection threshold. The detection threshold is calculated by multiplying a scaling factor times the variance of the signal indicative of the ambient noise, and adding that product to the mean of the signal indicative of the ambient noise in the underwater environment. A transmitter then excites a transducer which emits sonar pulses into a body of water, and a receiver receives reflected sonar echo signals. When the intensity of the reflected sonar echo signals is less than the detection threshold, the reflected echo signals are eliminated from processing.

  • Patent number: 6076039
    Abstract: A method and navigation device for abbreviating names of cartographic markers. A navigation device has a processor, a display, an input, and a memory having cartographic data stored therein. The cartographic data includes names of geographical locations. Using the input, an operator of the navigation device enters a waypoint by selecting a desired geographical location. The processor retrieves from memory the geographic name associated with the selected location, and when the geographic name exceeds a desired number of characters, processes the name to abbreviate it to fit within the desired number of spaces. The abbreviation process involves eliminating spaces, vowels, one consonant of a pair of double consonants, one vowel of a pair of double vowels, and/or one or more special characters (e.g., colons, commas, apostrophes, slashes, symbols, or other punctuation marks) as necessary, to reduce the geographic name to the desired number of characters.

  • Patent number: 5936553
    Abstract: An electronic navigation device and method, for displaying a visual representation of navigational information in a selected perspective view, includes a processor, a display, a key pad input, a memory, and an antenna. Navigational information, such as way-points in an active route, hazards and landmarks, and the position, direction, and speed of movement of the navigational device, are entered into the processor. The processor determines a trapezoidally-shaped visible region based upon user inputs, clips the navigational information to the visible region, and transforms the navigational information within the visible region to a selected perspective viewing plane. Polygons, representative of highway lanes, are displayed on the display, in the desired perspective view, for each route leg of a route within the visible region.

  • Patent number: 5930200
    Abstract: A sonar depth sounder device, and a method for processing echo signals reflected from objects within a body of water, utilize a processor, a memory, a display, and a keypad connected to the processor. A transmitter excites a transducer which emits sonar pulses into a body of water, and a receiver receives reflected sonar echo signals. Particularly, signals that have reflected from an object suspended in the water have an intensity, a history time duration, and a depth spreading characteristic. The processor compares one or more of the intensity, history time duration, and depth spreading characteristic of the reflected signals with corresponding sets of parameters stored in memory, which sets of parameters are representative of one or more selected objects, cross-talk noise, and unidentifiable noise.
