Abstract
An apparatus provides a warning of propeller rotation or CO/CO2 hazard in a marine craft and includes a sensor in communication with the propeller to directly or indirectly sense rotation of the propeller and to generate a signal in response to the hazard, a controller coupled to the sensor to process the signal from the sensor, and a sensory alarm coupled to the controller to generate a warning alarm signal when the sensor returns a signal indicative of a predetermined state of hazard, namely actual rotation of the propeller from a nonzero rpm to a user or factory defined rpm or CO/CO2 levels at or above a predetermined maximum.
Claims18
An apparatus for providing warning of hazard to a swimmer in the proximity of a marine craft comprising:
- a sensor in communication with the propeller to directly or indirectly sense rotation or possible rotation of a propeller and to generate a signal in response to the rotation;
- a controller coupled to the sensor to process the signal from the sensor;
- and
- a sensory alarm coupled to the controller to generate a warning alarm signal when the sensor returns a signal indicative of rotation or possible rotation of the propeller where the warning alarm is arranged and configured on the craft to provide the alarm signal to the swimmer in the water that the propeller is rotating or possibly rotating.
An apparatus for providing warning of hazard to a swimmer in the proximity of a marine craft comprising:
- a sensor in communication with the propeller to directly or indirectly sense the hazard and to generate a signal in response to the hazard;
- a controller coupled to the sensor to process the signal from the sensor;
- and
- a sensory alarm coupled to the controller to generate a warning alarm signal when the sensor returns a signal indicative of a predetermined state of hazard,
- where the alarm signal is an underwater sonic signal.
An apparatus for providing warning of hazard to a swimmer in the proximity of a marine craft comprising:
- a sensor in communication with the propeller to directly or indirectly sense the hazard and to generate a signal in response to the hazard;
- a controller coupled to the sensor to process the signal from the sensor;
- and
- a sensory alarm coupled to the controller to generate a warning alarm signal when the sensor returns a signal indicative of a predetermined state of hazard,
- where the craft has a transom and where the alarm comprises a second alarm mounted on the craft above a waterline in the proximity of the transom.
An apparatus for providing warning of hazard to a swimmer in the proximity of a marine craft comprising:
- a sensor in communication with the propeller to directly or indirectly sense the hazard and to generate a signal in response to the hazard;
- a controller coupled to the sensor to process the signal from the sensor;
- and
- a sensory alarm coupled to the controller to generate a warning alarm signal when the sensor returns a signal indicative of a predetermined state of hazard,
- where the craft has an underwater surface and where the alarm is mounted on the underwater surface.
A method for providing warning of a rotation or possibly hazardous rotation of a propeller on a marine craft comprising:
- sensing the rotation or possible rotation of the propeller;
- generating a signal in response to the rotation or possible rotation of propeller;
- and
- generating a sensory alarm to provide a warning alarm signal when rotation or possible rotation of the propeller exists, where the warning alarm signal is arranged and configured on the craft to provide the alarm signal to a person in the water that the propeller is rotating or possibly rotating.
A method for providing warning of a hazard in the proximity of a marine craft comprising:
- sensing the hazard;
- generating a signal in response to the hazard;
- and
- generating a sensory alarm to provide a warning alarm signal when a predetermined state of the hazard exists,
- where generating the sensory alarm comprises generating an underwater sonic signal.
A method for providing warning of a hazard in the proximity of a marine craft comprising:
- sensing the hazard;
- generating a signal in response to the hazard;
- and
- generating a sensory alarm to provide a warning alarm signal when a predetermined state of the hazard exists.
- where generating the sensory alarm comprises generating an underwater signal.
An apparatus for providing warning of a CO or CO2 hazard to a swimmer in the proximity of a marine engine comprising:
- a sensor in communication with a waterline region in proximity to the marine engine to directly or indirectly monitor a CO or CO2 concentration and to generate a signal in response to the concentration;
- a controller coupled to the sensor to process the signal from the sensor;
- and
- a sensory alarm coupled to the controller to generate a warning alarm signal when the sensor returns a signal indicative of a CO or CO2 concentration beyond a predetermined threshold, where the warning alarm is arranged and configured to provide the alarm signal to a swimmer in the water, who is or might enter the monitored waterline region.
