Abstract

A warning device for indicating a position of a golf cart on a golf course with respect to a restricted area includes a transmitter of an energy wave and a receiver of the energy wave. In one embodiment, the receiver is mounted on the golf cart and the transmitter is located at the restricted area. In another embodiment, both the transmitter and receiver are mounted on the golf cart and a reflector for the energy wave is mounted at the restricted area. The energy wave contains information about the position of the golf cart with respect to the restricted area such that an indication of the position can be generated by lighting a lamp, or by generating a sound, or by generating a digital visual display.

Claims

1. A warning device for indicating the position of a golf cart on a golf course with respect to a restricted area comprising:

a transmitter for transmitting an energy wave;

a receiver means mounted on a golf cart for receiving said energy wave and for generating an output signal representing the position of said golf cart with respect to a restricted area of a golf course on which the golf cart is located;

a microprocessor means connected to said receiver means and responsive to said output signal for generating one of a plurality of control signals, each said control signal representing a different position of said golf cart with respect to said restricted area, a first one of said control signals representing an area where it is permissible to drive said golf cart, a second one of said control signals representing an area adjacent said restricted area and a third one of said control signals representing said restricted area; and

an indicator means connected to said microprocessor means and responsive to said control signal for generating an indication of the position of said golf cart with respect to said restricted area wherein said indicator means includes first, second and third lamps responsive to said first, second and third control signals respectively.

2. The warning device according to claim 1 wherein said transmitter means transmits said energy wave as a radar signal and said receiver means is responsive to said radar signal energy wave.

3. The warning device according to claim 1 wherein said transmitter means transmits said energy wave as a sonar signal and said receiver means is responsive to said sonar signal energy wave.

4. The warning device according to claim 1 wherein said transmitter means transmits said energy wave as a laser beam and said receiver means is responsive to said laser beam energy wave.

5. The warning device according to claim 1 wherein said transmitter means, said receiver means and said indicator means are mounted on said associated golf cart.

6. The warning device according to claim 1 wherein said receiver means and said indicator means are mounted on said associated golf cart and said transmitter means is located at said restricted area.

7. The warning device according to claim 1 including a reflector means positioned at said restricted area for reflecting said energy wave transmitted by said transmitting means to said receiver means.

8. The warning device according to claim 1 wherein said first lamp is a green light, said second lamp is an amber light, and said third lamp is a red light.

9. The warning device according to claim 1 wherein said indicator means includes a digital visual display of the distance between said golf cart and said restricted area.

10. The warning device according to claim 1 wherein said indicator means includes an amplifier and speaker responsive to said control signal for generating an audible indication of the position of the golf cart with respect to said restricted area.

11. A method of warning an operator of a golf cart as to the position of the golf cart with respect to a restricted area on a golf course comprising the steps of:

a. transmitting an energy wave containing information on the position of a golf cart with respect to a restricted area;

b. generating one of a plurality of control signals in response to receiving said energy wave, each said control signal representing a different position of said golf cart with respect to said restricted area, a first one of said control signals representing an area where it is permissible to drive said golf cart, a second one of said control signals representing an area adjacent said restricted area and a third one of said control signals representing said restricted area; and

c. generating an indication of the position of the golf cart with respect to the restricted area in response to said control signal utilizing first, second and third lamps responsive to said first, second and third control signals respectively.

12. The method according to claim 11 wherein step a. is performed by generating said energy wave from an antenna positioned in the restricted area.

13. The method according to claim 11 wherein step a. is performed by generating said energy wave from an antenna positioned on the golf cart to a reflector positioned in the restricted area.

14. The method according to claim 11 wherein step c. is performed by lighting one of a plurality of different colored lamps in response to said control signal.
