Title: Takayoshi Shimokawa: Innovator in Navigation Technology
Introduction
Takayoshi Shimokawa is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of navigation technology, holding a total of 3 patents. His work focuses on enhancing navigation devices and data processing systems, showcasing his expertise and innovative spirit.
Latest Patents
Shimokawa's latest patents include a navigation device, navigation method, and navigation system. The navigation device is designed to receive differential map data from a map delivery server via a communication line. This server checks for new intersections on a navigation route after updating map data. The navigation device then acquires this differential map data, which includes the new intersection. An update map data selection section determines if the intersection can be updated in time, while an update order determination section updates the differential map data in ascending order of the time required to reach the intersection.
Another significant patent is a method and system for data processing with recovery capability. This system controls the storage device subsystem from a database management system on a host computer. It allocates a log-dedicated buffer area on a disk cache in advance, writes log data into this buffer, and in the event of a host computer failure, reads the log data from the disk cache without accessing a disk device. This innovation shortens the time required to read necessary log information, thereby reducing system recovery time.
