Researchers Submit Patent Application, "Global Positioning System Speedometer", for Approval

September 3, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors McCord, Keith (Florissant, MO); Terry, Kevin (Uncasville, CT); Ahlbin, JR., Frank R. (Chshire, CT), filed on February 11, 2014, was made available online on August 21, 2014.

No assignee for this patent application has been made.

News editors obtained the following quote from the background information supplied by the inventors: "All known GPS speedometers use an external GPS antenna when in communication with a GPS. However, there are many problems with using an external GPS antenna. It is often difficult and sensitive to route the antenna wiring throughout the vessel or vehicle, as well as the susceptibility of this antenna to damage from exposure to the environment. An external GPS antenna and the associated wiring require expensive environmentally sealed and resistant coatings and materials, plus the basic costs of a separate enclosure unit of the antenna itself increase the costs of such a speedometer system. Additional costs and complexity rise since the external antenna requires an internal battery (power source) to retain location information for quick TTFF (Time To First Fix) as typically required of a GPS. When this battery ultimately dies, approximately 3 years after installation, the external antenna ceases to provide quick TTFF.

"Currently, all GPS speedometer indication instruments (gauge type indicators) require external antennas for acquiring a GPS signal.

"Thus there is a need for a GPS speedometer that overcomes the above listed and other disadvantages."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "The disclosed invention relates to a GPS speedometer comprising: a housing; a circuit board located in the housing; a microprocessor located on the circuit board; a GPS module located on the circuit and in signal communication with the micro-processor; a GPS antenna located on the circuit board and in signal communication with GPS module; and a readable speedometer display located on the housing and in signal communication with the microprocessor, where the readable speedometer display is configured to display the current speed of the vessel or vehicle calculated by the microprocessor based on data from a global positioning system.

"In addition, the disclosed invention relates to a GPS speedometer system comprising: a vessel, the vessel comprising an instrument panel; a GPS speedometer located on the instrument panel, the GPS speedometer comprising: a housing; a circuit board located in the housing; a microprocessor located on the circuit board; a GPS module located on the circuit and in signal communication with the micro-processor; a GPS antenna located on the circuit board and in signal communication with GPS module; a readable speedometer display located on the housing and in signal communication with the microprocessor, where the readable speedometer display is configured to display the current speed of the vessel or vehicle calculated by the microprocessor based on data from a global positioning system; and a global positioning satellite in signal communication with the GPS antenna.
