Ball to provide low-observable communications antennas for Navy shipsEngineers at Ball Aerospace & Technologies Corp. in Boulder, Colo., are providing a low-observable Integrated VHF/UHF/L-Band (IVUL) antenna system to Northrop Grumman Ship Systems (NGSS), of Pascagoula, Miss., for the U.S. Navy's Ticonderoga-class cruisers and Arleigh Burke-class destroyers. Ball's IVUL antennas, which will provide line-of-sight communications, are compatible with existing receiver hardware on the ships, yet offer improved reliability, reduced maintenance, and reduced radar cross section, company officials say. Ball is teaming with Southwest Research Institute in San Antonio, Texas. The IVUL antennas are to include UHF transmit/receive, VHF/UHF direction finding, and Joint Tactical Information Distribution System (JTIDS) transmit/receive.

These devices have potential use in personal computers, handheld computers, digital cameras, and other applications where nonvolatile memory is crucial, says Yang Yan, professor in the UCAL Materials Science and Engineering Department. The triple-layer devices are made from an embedded metal layer between two organic films, which couples to two electrodes. A positive voltage turns on the device, and the transition from the off state to the on state is equivalent to the writing process. The device remains in this state even when its power is turned off. Applying a reverse voltage pulse erases data.

The devices — the WEDPS512K32-XBX and the WEDPS512K32V-XBX — integrate four 512K by 8 SRAMs into one 16-millimeter-by-8-millimeter 143 plastic ball grid array, and range in speed from 12 to 20 nanoseconds. These devices are available in commercial, industrial, and military temperature ranges.

University Drive, Phoenix, Ariz. 85034, or on the World Wide Web at interface cards available in PC/104 from DDCEngineers from Data Device Corp. (DDC) in Bohemia, N.Y., are offering single-function MIL-STD-1553 data bus interface cards for the PC/104 format based on DDC-s Enhanced Mini-ACE terminal. The BU-65568 card has four dual-redundant bus controller/remote terminal/monitor channels. The cards are 16 bit, convection cooled, and comply with PC/104 specification version 2.3. DDC's BU-65568 cards some with free software, including a C library and drivers for DOS and VxWorks.

The EMC Compliance 3 software comes with standard tests that users can run without complex configuration or setup by choosing from the pre-installed list of tests, Schaffner officials say. Users can create complex sequences for specialized tests. The software drives common EMC test hardware and is adaptable to "virtually any test situation," company officials say.

Mainstream seeks to help designers to use commercially developed components for harsh-environment and mil-spec applications with reasonable assurance that the commercial components will operate in that environment for the life of the product. At the heart of mainstream are scrutiny of the lineage of components, an alliance with integrated circuit vendors, analysis of test reports, techniques to moderate environment-induced failures, and study of temperature affects.
