Abstract

A watercraft control system includes a transmitting device and a watercraft control device which receives transmitted signals from the transmitting device and maneuvers the watercraft to a fallen driver, pursues a diver, or the like. The transmitting device can also unlock various devices and systems on the watercraft by generating an authentic ID code. In other embodiments, a signal intensity is monitored to trigger a guidance system, while still other embodiments replace the transmitting device with on-board sonar systems.

Claims

1. A control system for a watercraft providing wireless communication between a user'"'"'s transmitting device and a processor on the watercraft, the control system comprising:

a portable transmitting device configured to transmit a signal; and

a watercraft control system comprising;

a receiver configured to receive the transmitted signal;

a processor configured to communicate with the receiver to process the received signal and verify the received signal'"'"'s authenticity, and configured to generate one or more operational commands when the received signal is authentic; and

one or more controls of the watercraft including at least one of a steering control, a throttle control, and a rigging control, the one or more controls configured to communicate with the processor to receive and perform the one or more operational commands including mechanically positioning the rigging control, locking or unlocking the steering control, and locking or unlocking the throttle control, thereby preparing the watercraft for use.

2. The control system of claim 1, wherein the one or more controls include the steering control and the one or more operational commands includes locking and unlocking the steering control.

3. The control system of claim 1, wherein the one or more controls include the throttle control and the one or more operational commands includes locking and unlocking the throttle control.

4. The control system of claim 1, wherein the one or more controls include the rigging controls and the one or more operational commands includes adjusting the rigging controls.

5. The control system of claim 1, further comprising a second portable transmission device, wherein the processor can distinguish between signals from the portable transmission device and the second portable transmission device, and wherein processor generates operational commands based on predetermined configurations associated with each of the portable transmission device and the second portable transmission device.

6. The control system of claim 1, further comprising a guidance system which determines positional or directional information, wherein the processor is configured to communicate with the guidance system and generate one or more operational commands to guide the watercraft to a desired location based on the positional or directional information.

7. The control system of claim 6, wherein the guidance system comprises a global positioning system.

8. The control system of claim 6, wherein the guidance system comprises one or more directional antennas.

9. The control system of claim 8, wherein the transmitted signal comprises one or more radio-frequency signals.

10. The control system of claim 8, wherein the transmitted signal comprises one or more ultrasonic signals.

11. A control system for a watercraft providing pursuit of a diver, the control system comprising:

a transceiver configured to transmit sonar waves and receive reflections of the sonar waves from objects; and

a processor configured to communicate with the transceiver to acquire signals representing the reflections, configured to determine which reflections represent desired shapes, and configured to generate one or more operational commands to guide the watercraft to a desired location proximate a location of the objects which correspond to one or more of the desired shapes.

12. A watercraft control device comprises:

means for receiving and monitoring a signal from a transmitting device;

means for detecting a direction of the transmitting device;

means for generating control signals for maneuvering a watercraft in said detected direction; and

means for outputting said control signals to control devices such that said watercraft moves in said detected direction,

wherein said transmitting device comprises a sonar transmitting device, and

wherein said means for detecting a direction further comprises means for receiving a reflected sonar signal off one or more objects, means for recognizing shapes in said reflected sonar signal in order to determine which of the one or more objects to follow, and means for determining a direction of the object to follow.

13. The watercraft control device of claim 12, therein said transmitting device is wearable on a user of a watercraft.

14. The watercraft control device of claim 12, wherein said transmitting device is wearable on a diver.
