Abstract
Abstract Device for a subject which is moving over the land is adapted to provide a mounting for a map of the immediate vicinity and having input signal means representing distance travelled and signal means representing changes of direction of travel, and responsive means which will move an object over the surface of the map to continuously represent the position of the subject with relation thereto.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
201 words
A map position orientation and location apparatus employing inexpensive and commercially available DC motors with a calculator, said apparatus indicating the position of a carrier such as a vehicle, on a map, comprising a map support adapted to be movably supported on a steering wheel, an electrical orientation DC motor for moving said map support with respect to said steering wheel, a localization device including a mobile reference mounted on said map support so that the mobile reference will move automatically above the map placed on the map support, said mobile reference being provided with a light source supported by the wires actuated by a pair of DC motors, roller means for supporting said map over said map support, a steering wheel position sensor connected to said calculator and providing a signal proportional to the steering mechanism of the vehicle, a vehicle displacement indicator including a displacement sensor connected to said calculator, a vehicle orientation indicator connected to said calculator, whereby said calculator monitors the mechanisms of the orientation of the map support and displacement of the mobile reference in response to electrical signals continuously provided by said vehicle displacement indicator, the vehicle orientation indicator, and the steering wheel position sensor.
Claim 2
Dependent Claim
201 words
A map position orientation and location apparatus employing inexpensive and commercially available DC motors with a calculator, said apparatus indicating the position of a carrier such as a vehicle, on a map, comprising a map support adapted to be movably supported on a steering wheel, an electrical orientation DC motor for moving said map support with respect to said steering wheel, a localization device including a mobile reference mounted on said map support so that the mobile reference will move automatically above the map placed on the map support, said mobile reference being provided with a light source supported by the wires actuated by a pair of DC motors, roller means for supporting said map over said map support, a steering wheel position sensor connected to said calculator and providing a signal proportional to the steering mechanism of the vehicle, a vehicle displacement indicator including a displacement sensor connected to said calculator, a vehicle orientation indicator connected to said calculator, whereby said calculator monitors the mechanisms of the orientation of the map support and displacement of the mobile reference in response to electrical signals continuously provided by said vehicle displacement indicator, the vehicle orientation indicator, and the steering wheel position sensor.
Claim 3
Dependent Claim
57 words
Apparatus according to claim 1, wherein said calculator is a micro-processor connected to receive an orientation signal from an electronic compass, said orientation signal showing the displacement between the map support and the magnetic north, and a displacement signal from the vehicle displacement indicator, said displacement signal indicating the distance of the displacement of the map support.
Claim 4
Dependent Claim
48 words
Apparatus as claimed in claim 1, wherein said map support includes a hub 7 adapted to be mounted on the steering wheel of said vehicle, a disk installed for free rotation with said hub and being linked to a support stationary on the vehicle via a linking mechanism.
Claim 5
Dependent Claim
33 words
Apparatus according to claim 1, wherein said wires comprise movable perpendicularly disposed driving wires slidingly attached to said mobile reference and being connected to an electrical power source to energize said light source.
