Protocol Analyzer Mid-Bus Probe

Anew mid-bus probe for the Summit™ T3-16 Protocol Analyzer from LeCroy (Chestnut Ridge, NY) can be connected to systems that utilize the Intel® mid-bus probe footprint specification. The probe uses a full-size connector that supports PCle® x8 lanes at 8 GT/s. Two mid-bus probes can be connected to a Summit T3-16 Analyzer and will support x16 lane widths. These probes can be used in conjunction with the unique lane swizzling feature on the Summit T3-16 Analyzer, which allows probe signals to be reorganized logically, to give developers flexibility in PCB layout.

Lightweight Spreader for SBCs

Advanced Digital Logic (San Diego, CA) has introduced the ADL945PC-LTSPREADER, a lightweight spreader for the ADL945PC family of single board computers. The ADL945PC-LTSPREADER is designed for any application where weight is important, such as mass conscious applications, UAV applications, handheld applications, etc. The ADL945PC-LTSPREADER has thermal performance in excess of 98% of the original ADL945PC-SPREADER (293162), but at a mass savings of nearly 45%. Like all of the thermal solutions offered for the PC/104 lines, the flat-plate mounting pattern on the ADL945PC is bolt-up compatible with all other 855 and 945 class thermal interface products.

Using Microelectrode Arrays for Cerebral Applications

The fundamental understanding of cerebral systems and associated diseases relies on the electrical recording of single neuron activity. This requires in vivo interfacing with neurons using micrometer-scale electrodes. Traditionally, this challenging task is being performed using: single wire electrodes, probes containing small ensembles of electrodes or, more recently, multi-electrode arrays. These electrode arrangements have the potential to gather signals in three-dimensional space and to provide important laminar information. However, the types of arrays that have been proposed so far are either restricted to sampling in a given plane or have difficulty in collecting data in complex regions, such as those found in highly convoluted cortices. Moreover, state-of-the-art micro-electrode systems are not (yet) suitable for obtaining highly stable signals over extended recording periods. In some cases, the probes are just too bulky to follow cortical motion in chronic applications. Also, the damage inflicted to tissue and the way tissue responds to the presence of a foreign body are presently restrictive to chronic neural recordings. Such a chronic use is, however, highly needed, since it allows the study of changes in population activity at single neuron level and at the interaction level with learning, memory and training.

How Cool Is That? Ensuring Effective Thermal Design

Proper thermal design of any electronics-based system is key to its long-term reliability. NASA engineering expertise in this area is renowned. The International Space Station (ISS) operates in a temperature environment from 250 degrees F (121 °C), down to a minus 250 degrees F (-157 °C), while maintaining a survivable internal temperature. Yet, in the commercial electronics industry many systems engineers have limited knowledge about thermal design. Furthermore, military and industrial customers with wide temperature range applications, want to save money by using commercially available off-the-shelf (COTS) equipment.

Managing a Network of Self-Encrypting Hard Drives

With high-profile data breaches making headlines regularly, organizations are carefully evaluating their options for protecting mobile data. For years, software full disk encryption, (FDE), has been the preferred means of addressing this threat. But widespread adoption has been hampered by the complexity and cost surrounding these software-based FDE deployments.

Source Code Analysis Tool

AdaCore (New York, NY) has released CodePeer, a source code analysis tool that detects run-time and logic errors in Ada programs. Serving as an efficient code reviewer, CodePeer identifies constructs that are likely

to lead to run-time errors such as buffer overflows, and it flags legal but suspect code typical of logic errors. CodePeer also produces a detailed analysis of each subprogram, including pre- and postconditions, making it easier to find potential bugs and vulnerabilities early. If the implicit specification deduced by CodePeer does not match the component’s requirements, a reviewer is alerted immediately to a likely logic error.

Fanless Industrial Panel PC

The IPPC-8151S from Advantech (Cincinnati, OH) is a 15" XGA TFT LCD fanless industrial panel PC that features an Intel Celeron®M 1GHz CPU. It includes a tapered and food-safe rubber seal between the bezel and the chemical-resistant touch screen, and an optional fully sealed 316L stainless steel enclosure to satisfy the standards required in food processing, clinical, chemical, or pharmaceutical applications. For waterproof and dust-proof protection, the standard model supports IP66 grade protection on the front panel only, while an optional stainless steel enclosure kit and IP66 I/O module are available to support a fully enclosed IP66 protection for all sides, including I/O ports. The system includes a 1MB L2 cache, 1GB DDR2 memory, a CompactFlash slot, one PCI expansion, and one SATA HDD.

Considering Software Protection for Embedded Systems

Given the current trend of reprogrammable embedded devices within the Department of Defense and industry, attention needs to be refocused on the benefits or measurability of software protection applied to this domain. Modern reconfigurable embedded systems consider circuits as software and the tamper methods applicable to physical circuits as new threats to a broadened definition of software.

Field-Programmable Gate Array-Based Software-Defined Radio

There are existing wideband communications systems that were built using field-programmable gate array (FPGA)-based software-defined radio (SDR) designs. Despite the inherent advantages of these systems, some are functionally restricted by limited output bandwidth.
