Digital-to-Synchro/Resolver Converter

North Atlantic Industries (NAI) (Bohemia, NY) has announced the availability of a 3-channel Digital-to- Synchro/Resolver Converter on a PC-104 card. The DSP-based 73DS2 includes up to three independent, transformer isolated programmable synchro/resolver simulation channels. Each channel has 16-bit resolution, ±1 arcminute accuracy, and a short circuit protected output with 1.2 VA drive capability. The unit requires +5VDC and ±12VDC power supplies, and operates over a frequency range of 47 Hz to 10 KHz. Each unit includes eight programmable digital input/output channels, wrap-around self-test, programmable output angle rotation, and an optional programmable excitation reference supply.

EPIC and EBX Enclosures

WinSystems (Arlington, TX) has released the ENC-EPXG- 1000 enclosure for EPIC (Embedded Platform for Industrial Computers) and the ENC-EBC-G-1000 enclosure for EBX single board computer (SBC) systems. They are designed for embedded applications requiring mounting inside NEMA boxes, OEM machinery, wiring closets, equipment rooms, and other areas where it is necessary to protect an EPIC or EBX Single Board Computer system with PC/104 expansion. The enclosures are made from rustproof, lightweight aluminum. Aluminum is non-combustible, non-magnetic, non-sparking, non-toxic, recyclable, and thermally conductive to dissipate component heat.

Omniscient Code Generation for 8-, 16- and 32-bit Microcontrollers

C-language programs are usually developed by teams of engineers who are often geographically dispersed, leading to redundant code and inconsistent variable declarations between modules. Traditional compilation technology compiles each module separately with no regard for what goes on in the other modules and with no information about how pointers, stacks, variables and functions are used throughout the whole program. Traditional compilers tend to over-allocate memory space for pointers, stacks and registers. They are unable to fully exploit the wide variety of memory maps, and register and stack configurations available in today’s micro-controllers. All too often, the programmer must resort to manual optimizations that compromise portability (Figure 1).

Using AdvancedTCA and MicroTCA in High-Availability Military Systems

The complexity of military and aerospace systems is growing — more components, interfaces, power, bandwidth, processing, features, and data — and these systems are being networked to form even more complex "systems of systems." Modern networkc-entric systems can contain hundreds, even thousands of electronic modules.

Multipurpose Transaction Protocol: A New Data Transport Model

It is no secret that high-performance and the Internet are often seen as contradictory terms. Even private IP networks see serious performance challenges once they extend beyond the local building and around the globe. As devices and their users become more mobile, it has become critical to design with high-speed, Wide Area Networks in mind. But software and hardware designers are traditionally given few choices and little control for ensuring high network performance.

Wireless Electronic Patches Improve Medical Data and Patient Mobility

Non-invasive and ambulatory monitoring of body parameters is receiving much interest from the medical, sports and entertainment world. Possible applications are the monitoring of brain waves to detect epilepsy, monitoring of muscle activity during an athlete's training, and monitoring of heart rate during gaming. The idea is to develop small, low-power, autonomous biomedical monitoring systems that collect and process data from human body sensors and wirelessly transmit the data to a central monitoring system.
