Partnership Begins on Maintenance-Support Docking Station

Sealevel Systems was selected to design and manufacture docking stations for VT Miltope’s At-Platform Automatic Test Systems (APATS) Integrated Family of Test Equipment (IFTE) Maintenance Support Device — Version 3 (MSD-V3) tool. The project is part of the Hope Hull, AL-based, rugged computer supplier’s five year Indefinite Delivery Indefinite Quantity (IDIQ) contract, which was awarded in September 2009 by the Test, Measurement and Diagnostic Equipment (TMDE) Product Directorate of the U. S. Army. Sealevel Systems will design and manufacture the docking stations used with VT Miltope’s latest ruggedized laptop computer core.

Disposable Chemical Sensor and Wireless Communication Device

A disposable chemical sensor and temperature device has been developed that may be dropped into building rubble or other areas not accessible by rescue personnel to test the environment in the rubble. The system also provides wireless two-way communication and control to obtain information concerning the environment prior to disturbing an area under the rubble, and gives an indication of the likelihood that the area is a candidate for finding survivors. In addition, it would provide two-way communication between a survivor trapped in the rubble and a surface rescue worker, such that a survivor can be alerted to the fact that he or she should make a sound to make his or her presence known.

Fabrication of Transparent Carbon Nanotube Films for OLED Applications

The process to prepare single-wall carbon nanotube (SWCNT) solutions with a good degree of dispersion of individually isolated SWCNTs and very thin SWCNT bundles was optimized. The SWCNT-dispersion solutions are so stable that they can be stored and used repeatedly for some period of time.

Environmental Awareness of Sensor and Emitter Employment

Many Army missions rely on effective sensing capabilities that provide intelligence on the adversary, and protect friendly forces from enemy detection. Sensors that are stationary (microphones, geophones, and ground-based radars) and moving (cameras on unattended aerial vehicles and ground vehicles) assist operations such as persistent surveillance of small, forward-operating bases, and rapid covert troop maneuvers in the air and on the ground. When advantageous, sensing is often performed in multiple signal modalities including visible, infrared, acoustic, seismic, radiofrequency, chemical, and biological.

Ultraviolet Polymerization of Hydrodynamically Shaped Fibers

Materials composed of stacked plates are stronger than the same materials in bulk. However, such stacked plate materials are generally composed of hard, inorganic materials cemented together by a more flexible substance, and do not occur in long fiber shapes. Very few natural or manmade materials are composed of stacks of plate-like fibers. Manmade polymer fibers are nearly always round because they are fabricated using two-phase systems; for example, a solubilized polymer precursor or a monomer–initiator solution is introduced into air by electrospinning, extrusion, or pulling.

360-Degree Visual Detection and Target Tracking on an Autonomous Surface Vehicle

Operation of autonomous surface vehicles (ASVs) poses a number of challenges, including vehicle survivability for long-duration missions in hazardous and possibly hostile environments, loss of communication and/or localization due to environmental or tactical situations, reacting intelligently and quickly to highly dynamic conditions, re-planning to recover from faults while continuing with operations, and extracting the maximum amount of information from onboard and offboard sensors for situational awareness. Coupled with these issues is the need to conduct missions in areas with other possible adversarial vessels, including the protection of high-value fixed assets such as oil platforms, anchored ships, and port facilities.

Machine Control Interface Module

Trio Motion Technology (Tewkesbury, UK) has added to its MC464 Motion Coordinator machine controller range with the launch of its new EtherCAT Master drive interface module. The new module provides tightly synchronized control for up to 64 slave axes on the MC464 — up to seven modules may be added, each providing eight 100 nanosecond registration inputs which can be mapped to any axis. Trio’s MC464 Motion Coordinator is based on the 64-bit 400MHz MIPS processor with 64-bit position registers and double floating point maths for exceptional servo precision. With multitasking TrioBASIC programming, the central control unit includes analogue and digital I/O, status display, SD card memory expansion, axis synchronization and programming ports with a wide choice of half-and full-height expansion modules for drive technology, I/O expansion, factory and fieldbus communication.

Stand-Alone Real-Time Clock/Calendar

Microchip Technology (Chandler, AZ) recently announced its first stand-alone I2CTM Real-Time Clock/Calendar (RTCC) family. All six MCP794XX devices are highly integrated at a low cost, including ample amounts of on-chip EEPROM and SRAM, as well as a user-lockable section of EEPROM available for a 64-bit reprogrammable unique ID that can be factory-programmed with a MAC address. The devices include digital trimming for time-of-day calibration, and a battery-switchover feature that supports backup power at very low voltage and current levels.
