Using RFID to Protect System Firmware

Breeching the security of safety- or security-intensive products such as auto parts, set top boxes, military electronics, or smart batteries can be a lucrative business that is well worth the nominal investment required to create lookalike packaging and labeling, or to change the system firmware to allow unpaid access to licensed content. Because the counterfeiter does not incur any of the costs associated with product development, he quickly covers his capital investment at the expense of the authentic product manufacturer or service provider.

Board Versus Box: The Age-Old DAQ Dilemma

Since the beginning of PC-based data acquisition and control in the 1980s, one question has remained a constant consideration for all who would specify a new DAQ system. Is this application better served by an external I/O “box” connected to the PC via some communications link, or an internal “board” system plugged into a slot within the computer? If anything, this question has become more complicated as technology has progressed.

Adopting Aerospace Development and Verification Standards for Software

An ever-increasing reliance on software control has meant that many companies from non-aerospace business sectors (automotive, nuclear power, MRI scanners, financial systems) that do not have a traditional requirement for sophisticated software development processes now find themselves compelled to undertake safety-critical and safety-related analysis and testing. With the need for increased software quality across different industries, a tendency has emerged for companies to look outside their own market sector for best practice approaches, techniques or standards. Examples of such industry crossover have been seen in the automotive and avionics industries with the adoption of elements of the DO-178B standard by the former and a similar adoption of the Motor Industry Software Reliability Association (MISRA) standards by the latter.

Seven Practical Steps for Designing Networking Enclosures

The design of enclosures to house networking servers and components should be guided by one overriding concern — heat. Servers, in particular, generate a great deal of heat, so an enclosure must be capable of dissipating that heat to ensure that the components deliver their expected life.

VME NAS RAID Blade

ACT/Technico (Warminster, PA) now offers the VME RAIDStor, a single-slot 6U network attached storage (NAS) blade that provides the same automatic, transparent data replication and re-sync of traditional box-level RAID storage modules in a more compact footprint. With network access for up to 18 slots (up to 1/2 terabyte per slot) in a 19" chassis, the SATA-based VME RAIDStor is suitable for use throughout many industries in a number of high availability, data intensive applications including message processing, network- centric military environments, redundant self-hosted Web servers or storage repositories, as well as transaction processing and logging.

Network Analysis Software

OMICRON Lab (Houston, TX) has released new operation software for its Bode 100 portable network analyzer, giving users access to an extended frequency range. With the release of Bode Analyzer Suite V2.2, OMICRON Lab has managed to reduce the lower frequency border down to 1 Hz, giving the Bode 100 a range of 1 Hz – 40 MHz for Gain/Phase and impedance measurements. This extended frequency range makes the Bode 100 suitable not only for classical network analysis but also for the analysis of control circuits (e.g. DC/DC Converters), audio and ultrasound measurements, and the measurement of piezoelectric sensors and transducers. Other features of the new operation software include a straightforward and intuitive graphical user interface and OLE compatible automation interface, which facilitates integration of the Bode 100 into automated measurement setups for a variety of manufacturing or quality control applications.

Compact Embedded Computer

Mercury Computer Systems (Chelmsford, MA) has introduced the PowerBlock™ 50 system, a high-performance, ultra-compact embedded computer. The system’s modular architecture allows for flexible configurations of multiple processors, delivering well over 100 GFLOPS of processing power in a small, lightweight package. A fully configured PowerBlock 50 weighs less than 10 pounds and measures approximately 4" × 5" × 6". The system is available now as the PowerBlock 50 EDK (Engineering Development Kit), which is a complete software development platform. The EDK includes a PowerBlock 50 system, Linux BSP development environment, and a desktop heat rejection unit (HRU) to support the PowerBlock 50’s cooling requirements. The PowerBlock 50 EDK is customizable into configurations that include PowerQUICC™, Virtex™-4, and Intel processors, and SATA storage. Each configuration includes Gigabit Ethernet and RS-232 I/O interfaces.
