摘要:
A GPS device and method for converting display information between a first display mode and a second display mode by negativizing pixels or other image elements, wherein negativizing entails converting relatively larger areas of lighter image elements to darker image elements and converting relatively smaller areas of darker image elements to lighter image elements so as to result in reduced total emission of light.
摘要:
A GPS device and method for conditioning and hierarchically layering or ordering a plurality of static or dynamic image, information, tool, control, or other elements for simultaneous display in such a way as to minimize interference and maximize total benefit from and usability of the various elements.
摘要:
A GPS device adapted and operable to download and store, receive, or otherwise obtain and display any of a variety of different types of geo-referenced raster images, such as, for example, aerial photographs, and to integrate those images into a scheme of information which is relevant to navigation and travel generally.
摘要:
A GPS device and method for quickly and automatically determining and implementing an appropriate scale or area for displaying simultaneously at least a current location and a previously designated or otherwise identified waypoint, trail, track, or other geo-referenced indicator associated with a location. Relative distance, direction, and other useful navigation information may also be determined and displayed.

摘要:
The present invention provides a method for converting display of information on a GPS device between a first display mode and a second display mode by “negativizing” pixels or other image elements, wherein negativizing entails converting lighter image elements to darker image elements and converting darker image elements to lighter image elements so as to result in reduced total emission of light.

摘要:
An apparatus (10) and method for allowing a moving user to automatically determine and store locations (11) over an extended period of time, to display the series of such locations (11), and to actively assist in returning to an earlier location. The apparatus (10) includes an antenna (16) for facilitating satellite lock, a fastening mechanism (18) for positioning the antenna (10) for best reception, and a satellite lock indicator (20) for communicating loss of satellite lock. The apparatus (10) also includes a timer (26) for measuring an interval during which the apparatus (10) is in a power-conserving sleep mode, and after which the user's current location is automatically determined. Active assistance in returning to an earlier location, either by traveling back along the path earlier traveled or by traveling along a more direct route, is accomplished by warning the user whenever the user's course deviates from the path or route.
