Title: Lei Zhao - Innovator in Navigation Systems
Introduction
Lei Zhao is a notable inventor based in Torrance, California. He has made significant contributions to the field of navigation systems, holding a total of 2 patents. His work focuses on improving route calculation and search performance in navigation technology.
Latest Patents
One of Lei Zhao's latest patents is titled "Method and apparatus for establishing optimum route to intersection destination for navigation system." This invention provides a method for calculating an optimal route to an intersection destination by creating a virtual zero-length dummy link. This link connects to all link-spot pairs indicating the original intersection destination, allowing the navigation system to calculate possible routes and select the best one. Once the optimum route is determined, the system removes the dummy link and initiates route guidance to the destination.
Another significant patent is the "Link promotion method and apparatus for improving route search performance for navigation system." This invention enhances the search process in navigation systems by allowing the expansion of search in a lower layer to find an optimum climbing point to an upper layer. The method includes determining the existence of an upper link for a lower link and setting it as a promoted link, even if a climbing node point does not exist. This process helps in comparing candidate routes to identify the best option.
