Abstract
A database system for a global positioning (GPS) vehicular navigation device having a first database comprising street information data; a second database, comprising location information data that is independent of the first data; a working memory unit comprising a first memory area and a second memory area separate from the first memory area, where the first data comprising street information is stored in the first memory area and the second data comprising location information is stored in the second memory area.
Claims39
A database system for a navigation device, comprising:
- a first database comprising at least first data;
- a second database comprising at least second data independent of the first data;
- where the first data comprises street information and the second data comprises location information;
- a working memory unit comprising a first memory area and a second memory area, where the first data is stored in the first memory area and the second data is stored in the second memory area;
- and a processing unit.
A global positioning navigational system comprising:
- a GPS receiver;
- a first database comprising first data;
- a second database comprising second data independent of the first data;
- a working memory unit comprising a first memory area and a second area, and
- a processing unit;
- where the first data comprises street information and the second data comprises location information and where the first data is stored in the first memory and the second data is stored in the second memory area.
A method for providing information to a navigation device, comprising:
- storing data of a first type in a first location;
- storing data of a second type, independent of the first type of data, in a second location;
- providing data of the first type to a first dedicated memory area of a working memory unit;
- providing data of the second type to a second dedicated memory area, separate from the first memory area, of the working memory unit;
- processing either or both the first and second type of data;
- and
- providing the processed data to the navigation device;
- where the first type of data comprises street information and the second data type comprises location information.
A method for operating a navigation device in a vehicle, comprising:
- detecting a GPS signal identifying the location of the vehicle;
- retrieving a first type of data comprising street information from a first location;
- providing the first data to a first dedicated memory area of a working memory unit;
- retrieving a second type of data, independent of the first data, comprising location information from a second location;
- providing the second type of data to a second dedicated memory area of a working memory unit;
- processing the first data and the second data,
- providing the first and second data to the navigation device;
- and
- presenting the first and second data on the navigation device.
