1. A personal digital assistant (PDA), comprising:
- a calendar function;
an address book function;
a processor operably in communication with a memory and a display;
wherein the PDA uses the memory in cooperation with the processor to dynamically generate one or more scores associated with one or more roads included in a route path for the device, wherein a current score associated with a current position of the device is biased by a factor in favor of the current position being on the route path; and
wherein at least a portion of the route path is dynamically communicated to the display.

Abstract
PDA devices, systems, functional data and methods are provided for biasing an active location to an acceptable location within a planned route of a map. A PDA with map biasing capabilities includes a processor communicating with a memory. In biasing a map, an active position and a planned position are received, and an active score and a planned score are associated with each position, respectively. The active position is checked to ensure it falls within a second range, and if it does the active score is made to fall within a first range associated with the planned score, such that the active position is biased to appear as if it were the planned position.

9. A PDA system, comprising:
-
a storage device operable to store navigation data;
a server operable to communicate with the storage device; and
a PDA device operable to communicate with and retrieve navigation data from the server via a communication channel, wherein the PDA includes a processor in communication with a memory, wherein the processor and memory cooperate to generate a current score associated with a current position and a current bearing of the PDA, the current score is used to determine whether the PDA is located on a planed route for the PDA and is biased to map the current position to a position on the planned route for the PDA and whether the current score is within a tolerance level. - View Dependent Claims (10, 11, 12)

13. PDA functional data to bias a location to a map, comprising:
-
in a PDA, active location data operable to be plotted within the map;
a planned path including planned location data operable to be plotted within the map;
an active score associated with the active location data and a planned score associated with the planned path; and
bias instruction data to bias the active score in favor of the planned score as long as the active location data do not deviate from the planned path by a preset range. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method to bias an active position to a planned position for a PDA, comprising:
-
in a PDA, dynamically receiving the active position and the planned position;
biasing an active score associated with the active position by forcing the active score to be at least as favorable as a planned score associated with the planned position ensuring that the difference between the active score and the planned score fall within a first range; and
aborting the biasing if the active position falls outside a second range. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)

28. A personal digital assistant (PDA), comprising:
-
a calendar function;
an address book function;
a processor operably in communication with a memory and a display;
means for dynamically generating one or more scores associated with one or more roads included in a route device, wherein a current score associated with a current position of the device is biased by a factor in favor of the current position being on the route path; and
means for dynamically communicating at least a portion of the route path to the display.
