The Davidson

Laboratory com- bines experimen- tal and numerical methods to solve complex prob- lems related to surface and sub- surface vessel dynamics. The experimental facilities include a high speed towing tank with wave generation capability and a rotating arm tank.

The laboratory has tested hydrodynamic scale models of all types of craft (sail boats, yachts, planing craft, sea- planes, submarines, torpedoes) to assess their performance for calm water resistance, propulsion, seakeeping and maneuvering. Numerical modeling using advanced CFD codes is performed and provides an excellent supporting tool to our experimental towing tank.

Viperfish MSX (Marine Spec. Xtreme): Designed for top side applications, the Viperfish MSX is a high per- formance shock and vibration proof digital recorder that converts analog video to digital format. It records high resolution video (720 x 486 pixels), at full-speed 30 frames per second with zero latency.

Viperfish Amphibian: Designed for intense environ- ments, the Viperfish Amphibian is a ruggedized all-weath- er, digital video recorder. Viperfish Amphibian converts analog signals to digital format and records non-multi- plexed video up to 640 x 480 pixels to a high capacity hard drive.

Viperfish Deep: Record high resolution video at depths up to 1,000 feet on a rugged digital platform. Clear, real- time, full-speed, non-multiplexed video is recorded to a rugged hard drive. This battery operated submersible dig- ital recorder is power self sufficient providing flexibility and reliability for all your underwater recording needs. It converts analog video to digital format storing it at 720 X 480 frames full speed 30 FPS.

To ensure top security of data, tampering, jamming and eavesdropping - Viperfish Amphibian wireless transmis- sion option frequency hops at 110 times per second at a minimum of 6 mega hertz per hop. Data is encrypted with forward error correction. The frequency range is 902 to 928 band (approximately 104 channels). Viperfish high resolution recorders are ideal for marine research or underwater applications.
