 | This user has publicly declared that they have a conflict of interest regarding the Wikipedia article David Heath. |
David Heath is an inventor that was born in Kansas City, MO (born 1969). He lived with his mother until the 10th grade in high school, when they lost their home. He quit high school, and worked at Wehadkee Yarn Mills at night and completed his GED.
David then went to Jacksonville State University, where he got a BS in Biology and enrolled in ROTC to help pay for college.
Biography ——————————————————————————————————————————————
He started a Master's in Public Administration to finish ROTC, and as he was about to start his last semester, the Army sent him to the Armor Regiment|1st Battalion, 77th Armor Regiment Schweinfurt, Germany. He then served with the 3rd Infantry Division HHB Artillary.
David went on to complete a MS CIS at the University of Phoenix, and a MBA from Auburn University While working for various software companies.
He then worked on data synchronization between remote rovers on other planets, satellites, cell phones and ground stations in remote locations. Synchronizing remote data can take minutes, hours, days depending on the amount of data and the distance. By the time the data is received, it may be out of date and useless.
An example of this is a game development company that creates its code in the West coast of the US, its graphics in Europe, and its music in Asia. As the code is created, it can then take a day or more to be sent to Europe. By the time it arrives, the graphics team is already working on outdated software and will have to redo their work once they receive the update. The same can happen in Asia as the game and graphics can be 50, 100 Gig and can take more than a day to update. Asia and Europe will always have old code.
Keeping these remote groups updated and working on the latest software is the purpose of these patents.
Likewise sending an image from Mars can take between 4.3 minutes and 21 minutes[1]. Sending many images will cause a backup or delay in receiving these images or sensor data. Staying in synch with remote operations in real-time is an important task that these patents address.
In the first patent[2], David explains that there are two or more computers that need to be synchronized. In this case, we will use two. If the mars rover takes a photo and sends it to earth it will take between 4.3 minutes and 21 minutes[3] to complete. If the rover then turns its camera a few degrees and takes another picture, it will have captured some of the same landscape.
Rather than immediately send this second picture, the system can compare the first photo and the second photo and determine where and what data has changed from the first. Since the first photo contains some of the same data in the second, that data does not need to be sent again. Instead, the system can send the updated data and its location(s) to be inserted to a copy of the first file to make it match the second image from the rover.
If 80% of image two is the same as image one, then the data will transfer roughly 80% faster. likewise, if only 40% of the data in image one is in image two then the data will transfer roughly 40% faster.
This can save valuable time, reduce battery usage by transmitting shorter messages, and thus may extend the battery life of the rover over time.
On April 4, 2016 a new patent[4] was issued that extended this capability.
To use the example of the game developer on the West coast, Europe, and Asia. If we modify the scenario to use this technology, as the coders make changes and commit the code the changes can be seen and automatically synchronized with the code in Europe and in Asia. Most new games are larger than their predecessors and can be well over 100Gig or more[5], and only a small portion of the code changes day to day, those code submission won't take a day or more to transmit and the graphic designers and audio engineers will have the latest code to work with almost immediately.

David currently holds 17 certifications in business and technology.
