Title: Innovations of John J De Matteo
Introduction
John J De Matteo is a notable inventor based in Doylestown, PA (US). He holds a total of 3 patents that showcase his contributions to technology and engineering. His work primarily focuses on advancements in marine technology and navigation systems.
Latest Patents
One of his latest inventions is the Quick Deployment Vehicle (QDV). This innovative vehicle is designed for implanting a transponder or beacon on the ocean bottom in an upright position, which is crucial for receiving or transmitting acoustic signals. The QDV features a ballistic body composed of separable fore and aft sections. The fore section is equipped with a core mass for penetrating ocean sediment, while the aft section contains a beacon for signal transmission. After a predetermined interval post-impact, the sections separate based on a programmed deceleration profile stored in memory. The aft section remains exposed above the sediment, while the fore section penetrates deeper into the ocean bottom.
Another significant patent is the Gravity Measurement Apparatus for Ships. This invention utilizes the output of a vertical accelerometer from a ship's inertial navigation system (SINS) to provide a pulse form output that relates directly to total acceleration. The SINS computer calculates the latitude and velocities of the ship, which are then used to determine theoretical gravity and Coriolis error. These factors are subtracted from the total scaled acceleration, and the resultant output is filtered to remove the influence of the ship's heave acceleration. The final output represents the free-air gravity anomaly in real time.
