Underwater location and communication device
First Claim
1. An underwater location and communication device for use by a diver, said device comprising:
- an outer case or housing that is durable and waterproof;
a plurality of manually operable switches attached to said housing and used by said diver to operate said device;
an electronic display also attached to said housing and readable from the exterior of said housing by said diver;
a fastening means attached to said housing and used to permit said device to be worn by said diver;
a plurality of transmitter/receiver pairs affixed to said housing and employed to emit and intercept an ultrasonic wave;
an electric power source contained within said housing;
a plurality of warning means enclosed in said housing and employed to alert said diver when a distance limit selected by said diver between said device and a companion device worn and operated by a companion diver is exceeded;
a microcontroller circuit in electrical communication with said plurality of manually operable switches, said electronic display, said electric power source and said plurality of warning means; and
a transceiver circuit in electrical communication with said plurality of transmitter/receiver pairs and said microcontroller circuit.

Abstract
An electronic device for use by recreational divers, that uses ultrasonic signals to measure distance, to indicate relative direction, and to maintain contact between at least two diving partners during a diving session. One of the devices is worn and operated by each diving partner, and each device, through an arrangement of ultrasound transmitters and receiver pairs affixed thereto, monitors relative distance between itself and each other device in use by a diving partner. The device has a user interface, including a plurality of push-buttons and liquid crystal display, to set and indicate relative distance, relative direction, low battery fault, and chime or vibration warning mode. The warning mode alerts a diver when a distance limit between companion divers has been exceeded.
