Directional Acoustic Transponder (DAT)
-
The Benthos Directional Acoustic Transponder (DAT) is anextension to the Teledyne Benthos ATM-900 Series modem, which automatically estimates the azimuthal and vertical arrival angles of a message sent by a remote modem. The system is a modified ultra-short baseline (USBL) which uses a broadband component of a typical modem message to form estimates of arrival angle(s). While conventional USBL devices employ tonal signals, our appropriate processing of wide band signals provides far better combined range and arrival angle estimation, especially at low Signal to Noise Ratio (SNR). Our device offers a clear 360 degree field of view in azimuth, and an approximate vertical coverage spanning + 90º overhead to -50º below horizontal.

Series Voltage References
-
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.
