Abstract

The present invention is a system for providing an output corresponding tohe speed of a remote vehicle, comprising: a speed transducer mounted on the vehicle for providing a first output corresponding to the speed of the vehicle; a first data processor operably coupled to receive the first output from the speed transducer means for providing an ASCII coded output; a second data processor operably coupled to receive the ASCII coded output from the first data processor for providing an output transducer control output; and an output transducer operably coupled to receive the control output from the second data processor for providing an output having an amplitude proportional to the speed of the vehicle.

Claims

1. A system for providing an output corresponding to the speed of a remote vehicle, comprising:

speed transducer means mounted on the vehicle for providing a first output corresponding to the speed of the vehicle;

first data processor means operably coupled to receive said first output from said speed transducer means for providing a digitally encoded second output representing the first output;

second data processor means operably coupled to receive said second output from said first data processor means for providing a transducer control output; and

output transducer means operably coupled to receive said transducer control output from said second data processor for providing a transducer output having an amplitude proportional to the speed of the vehicle.

2. The system of claim 1 further including:

an operator support platform; and

where said transducer output is a vibration imparted to said operator support platform.

3. The system of claim 2 wherein:

said speed transducer means is an optical rotary shaft encoder having a phase-quadrature output.

4. The system of claim 3 further including:

a radio data link for conveying said digitally encoded second output from said first data processor to said second data processor.

5. The system of claim 2 wherein:

said speed transducer is a tachometer-generator.

6. The system of claim 5 further including:

a radio data link for conveying said digitally encoded second output from said first data processor to said second data processor.

7. A system for providing an output corresponding to the speed of a remote vehicle, comprising:

speed transducer means mounted on the vehicle for providing a first output corresponding to the speed of the vehicle;

first data processor means operably coupled to receive said first output from said speed transducer means for providing a digitally encoded second output representing said first output;

second data processor means operably coupled to receive said digitally encoded second output from said first data processor means for providing a transducer control output; and

output transducer means operably coupled to receive said transducer control output from said second data processor for providing an acoustic output having a frequency proportional to the speed of the vehicle.

8. The system of claim 7 further including:

an operator support platform; and

where

second digitally encoded output is an ASCII coded output.

9. The system of claim 8 wherein:

said speed transducer means is an optical rotary shaft encoder providing phase-quadrature outputs.

10. The system of claim 9 further including:

a radio data link for conveying said ASCII coded output from said first data processor to said second data processor.

11. The system of claim 8 wherein:

said speed transducer is a tachometer-generator.

12. The system of claim 11 further including:

a radio data link for conveying said ASCII coded output from said first data processor to said second data processor.
