Publication number: 20040193366Abstract: Devices, systems, functional data and methods are provided for biasing an active location to an acceptable location within a planned route of a map. The navigational device with map biasing capabilities includes a processor communicating with a memory. In biasing a map, an active position and a planned position are received, and an active score and a planned score are associated with each position, respectively. The active position is checked to ensure it falls within a second range, and if it does the active score is made to fall within a first range associated with the planned score, such that the active position is biased to appear as if it were the planned position.Type: ApplicationFiled: April 1, 2004Publication date: September 30, 2004Applicant: Garmin, Ltd.Inventors: Mark D. Tompkins, Jay Dee Krull

Publication number: 20040153239Abstract: Systems, devices and methods are provided for an improved navigational route planning device which provides more understandable, accurate and timely route calculation capabilities. The navigational aid device with route calculation capabilities includes a processor connected to a memory. The memory includes cartographic data and a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types. A display is connected to the processor and is capable of displaying the cartographic data. The device is adapted to calculate a route to navigate to the desired destination. And, the device is adapted to adjust a starting point for the route calculation to an appropriate location such that the device is on the route at a time when the route calculation is completed. The device processes travel along the route, recognizes when the device has deviated from the route, and calculates a new route to navigate to the desired destination.Type: ApplicationFiled: January 23, 2004Publication date: August 5, 2004Applicant: GARMIN LTD., a Cayman Islands CorporationInventors: Jay Dee Krull, Michael Childs, Scott M.

Patent number: 6735542Abstract: A navigation device and a method of calibrating the same are provided. The device includes a barometric pressure sensor and a GPS receiver. A processor calculates barometric and GPS derived altitudes and, based on a difference therebetween, corrects barometer altitude readings that would otherwise include drift errors. The processor uses a filter, such as a state feedback loop, to determine correction factors. The state feedback loop is adjustable to operate with different time constants. An error drift model is empirically determined and used to set the time constant. The time constant may be adjusted during operation based on a relation between the barometer correction quantity and an uncertainty in the vertical component of the GPS derived altitude. The method includes updating and recalibrating an atmospheric pressure model used to derive altitudes from the output of the barometric pressure sensor.Type: GrantFiled: June 25, 2001Date of Patent: May 11, 2004Assignee: Garmin Ltd.Inventors: Scott Burgett, Jay Dee Krull

Patent number: 6459987Abstract: A method for automatically generating a point-reduced backtrack route is provided, using the aid of Global Positioning System technology. The method begins by recording a potentially very large series of data points using GPS technology and a user-selected point recording algorithm into a forward-track route. A point-reducing algorithm is then used to reduce the forward track to a backtrack route which preserves the topological essence of the original route, but with far fewer data points. This reduced backtrack route is then suitable for storage in a memory constrained device, and is suitable for backtrack navigation without the need for the large set of original route points. Storage of a number of such backtrack routes is thus made available to the end user.Type: GrantFiled: November 15, 1996Date of Patent: October 1, 2002Assignee: Garmin CorporationInventors: Jay Dee Krull, Darin J.

Patent number: 6076039Abstract: 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.Type: GrantFiled: September 3, 1998Date of Patent: June 13, 2000Assignee: Garmin CorporationInventors: Darrin W.

Patent number: 5654718Abstract: A device and method for compensating a crystal oscillator that is not electrically compensated over its operable temperature range. A GPS receiver device stores in memory data indicative of the actual offset frequency of oscillation of the crystal over its operable temperature range. The first time the device is activated, the temperature at the crystal is sensed and data, stored in memory, indicative of the specified frequency offset of the crystal at the sensed temperature is retrieved, and used to control the receiver.backslash.decoder. When the receiver locks onto a sufficient number of satellites to calculate its two-dimensional location, the actual frequency offset of the crystal is calculated and stored in memory. Repeated use of the receiver device permits a database of actual frequency offset data of the crystal, over its operable temperature range to be stored. Subsequent uses of the device permit retrieval of this data for use in locking the receiver onto satellite signals.Type: GrantFiled: November 19, 1996Date of Patent: August 5, 1997Assignee: Garmin CorporationInventors: Lawrence W.
