Title: David S. Sprague: Innovator in Mobile Network Technology
Introduction
David S. Sprague is a notable inventor based in Portola Valley, California. He has made significant contributions to mobile network technology, holding a total of 7 patents. His work primarily focuses on enhancing communication systems through innovative solutions.
Latest Patents
One of his latest patents is titled "Mobile network with automatic position reporting between member units." This invention involves a network comprising multiple GPS navigation receivers that utilize two-way radio data communication. It allows for the current computed positions of individual mobile units to be communicated to other units in the network and to stationary dispatch controllers connected via the public switched telephone network. Additionally, the network supports ordinary telephone personal pager service for non-GPS equipped mobile units.
Another significant patent is "Outdoor movie camera GPS-position and time code data-logging for special." This invention features a GPS navigation receiver with a data output port that communicates position estimates frame-by-frame along with time codes in SMPTE format. The conventional date and time output of the GPS navigation receiver is combined with a highly accurate one pulse-per-second signal to create a time-keeping base for the time code output. A data-logger records the position estimates with their corresponding time in time code format, which is then utilized in special-effects post-production for directing animation and modeling kinetics in final films or videos.
