Abstract
Abstract The invention relates to an information input for a navigation device for highway vehicles in connection with which map markings which represent optically readable information and can be read by a reading device and fed to a data processing unit of the navigation device can be associated with a map, in particular a road map. A mark 6 can be associated with a starting or target point on the map and optically readable location markings 2 and 3 can be read by the reading device in the associated position of the mark 6 to the starting or target point.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
132 words
A system for identifying locations on a map for inputting data of the locations into an optical map reading device of a navigation device, the locations including a start point and a target point, the navigation device including a data processor, the system comprising stencil means configured for emplacement on the map for measuring coordinate distances on the map, said stencil means including a mark for association with a starting point or target point on the map, and location marking means constructed with optically readable location markings, and being disposed on said stencil means for inputting location data into said reading device for use by said data processor, said location data being inputted upon alignment of said mark of said stencil means with a coordinate of the starting point or target point.
Claim 2
Independent Claim
132 words
A system for identifying locations on a map for inputting data of the locations into an optical map reading device of a navigation device, the locations including a start point and a target point, the navigation device including a data processor, the system comprising stencil means configured for emplacement on the map for measuring coordinate distances on the map, said stencil means including a mark for association with a starting point or target point on the map, and location marking means constructed with optically readable location markings, and being disposed on said stencil means for inputting location data into said reading device for use by said data processor, said location data being inputted upon alignment of said mark of said stencil means with a coordinate of the starting point or target point.
Claim 3
Dependent Claim
13 words
The system according to claim 1, wherein said location markings represent coordinate values.
Claim 4
Dependent Claim
17 words
The system according to claim 2, wherein said location markings comprise vertically and horizontally extending raster strips.
Claim 5
Dependent Claim
29 words
The system according to claim 3, wherein said location marking means includes an optically readable end marking and raster strip identifier arranged on one end of a raster strip.
Claim 6
Dependent Claim
33 words
The system according to claim 1, wherein said map comprises optically readable markings as imprints on the map, which markings are displaced from the location marking to permit reading by said reading device.
Claim 7
Dependent Claim
20 words
The system according to claim 5, wherein said optically readable markings are applied to the map by means of stickers.
Claim 8
Dependent Claim
35 words
The system according to claim 1, further comprising a support, wherein said map can be applied to said support, said support being provided with optically legible markings and orienting said map with said stencil means.
Claim 9
Dependent Claim
13 words
The system according to claim 7, wherein said support is a support plate.
Claim 10
Dependent Claim
19 words
The system according to claim 1, wherein said stencil means further comprises a transparent covering for covering said map.
Claim 11
Dependent Claim
23 words
The system according to claim 9, wherein said covering comprises a plurality of guidelines extending in the coordinate directions of said location markings.
Claim 12
Dependent Claim
12 words
The system according to claim 9, wherein said covering comprises a foil.
Claim 13
Dependent Claim
17 words
The system according to claim 1, wherein said mark comprises a vertically or horizontally extending reference line.
Claim 14
Dependent Claim
49 words
The system according to claim 1, wherein map markings are provided on the map to enter map identifying information into said reading device, the locating markings of said location marking means being positioned on said stencil means away from the map markings to permit reading by said reading device.
Claim 15
Dependent Claim
24 words
The system according to claim 1, further comprising means aligned with said stencil means for optically feeding program commands to the data processing unit.
Claim 16
Dependent Claim
17 words
The system according to claim 14, wherein optically readable number identifiers are associated with the program commands.
Claim 17
Dependent Claim
20 words
The system according to claim 15, wherein said map markings, program commands and number identifiers are formed by bar codes.
Claim 18
Dependent Claim
29 words
The system according to claim 15, wherein the locating markings, the map markings, the program commands, and the number identifiers are optically readable by means of a light pen.
Claim 19
Dependent Claim
26 words
The system according to claim 17, wherein said location marking means comprises a guide edge wherein said light pen can be guided along said guide edge.
Claim 20
Dependent Claim
20 words
The system according to claim 1, wherein said location marking means comprises optically readable markings provided with reading direction characters.
Claim 21
Dependent Claim
35 words
The system according to claim 1, wherein said stencil means is formed by a vertically or horizontally extending edge of a stencil which edge can be placed along a corresponding reference line of the map.
Claim 22
Dependent Claim
17 words
The system according to claim 20, wherein said stencil can be associated with a plurality of maps.
Claim 23
Dependent Claim
18 words
The system according to claim 20, wherein said stencil comprises map markings, program commands, and said number identifiers.
