New Digital Underwater

Communication System

ELAC Nautik recently introduced its new model UT 3000 for cus- tomers with extended communica- tion requirements. In addition to the features of the UT 2000, this new underwater communication system is designed to be capable of establishing a digital link for data transfer and vocoder applications.

Different transmission modes enable the selection of the optimum communication channel. Standard and customizable interfaces of the

UT 3000 support integration in the ship's communication network and enhance the communication options by interaction with connected sys- tems.

ELAC Nautik's underwater com- munication systems family is comple- mented by the UT 2200 serving as an emergency system onboard of sub- marines or as a mobile device.

New Ocean Measuring

Instrument

Ocean Sensor Systems released the new OSSI-010-006 Wave Staff II water level sensor that combines a sealed, waterproof package, low power microprocessor and a tempera- ture stable, sensing circuit. The Wave

Staff II operates from 5.5V to 40VDC and has analog and RS232 serial data outputs. The serial data output string contains the water level & temperatures in ASCII or binary format.

The Wave Staff II can be pro- grammed to free run or sample on demand. It is easily programmed via a PC serial port using our Wave Staff

Interface Software. The Wave Staff II has two new features. The Coaxial

Cable Staff eliminates the need for a separate water ground wire and both

Staff & electrical cord are changeable.

Price ranges from $942 to $1100 depending on staff length.

Modular Batteries for

UUV & Submersible

Applications

Lithion Inc. introduced a new high- capacity modular battery system using Lithium-ion technology.

Based on the ASDS (Advanced

SEAL Delivery System) battery devel- oped for the U.S. Navy, it is designed to allow the safe storage of over 1.2

MW/hours of energy in a rugged, compact design. The system can be broken down into its three primary elements: the individual Lithium-ion cells; the Lowest Replaceable Units (LRUs); and the Battery Modules.

The individual cells are 3.6 volt (nominal), 350 Ampere-hour cells, and feature high-grade stainless-steel shells. Each cell is hermetically sealed using a laser welding system. In addi- tion, each battery system is equipped with an electronics package known as a Battery Management System (BMS), which monitors the status of each cell in the entire battery system, in addition to battery temperatures in several locations.
