Mini Embedded Systems

4DSP (Austin, TX) builds mini embedded systems in the FMC (FPGA Mezzanine Card) form factor. The FMCs are stacked over one another. A typical system features a 12V-30V DC input power supply; Atom CPU + 64GB SSD + Gigabit Ethernet; and Kintex-7 FPGA with 1 GB DR3 SDRAM. The ruggedized, approximately 3" × 3" form factor can be conduction cooled.

Military Grade Lithium Batteries

Tadiran (Lake Success, NY) has introduced the TLM Series of military grade lithium metal oxide batteries. TLM military grade batteries are cylindrical in shape, constructed with a carbon-based anode, multi metal oxide cathode, organic electrolyte, and a shut-down separator for enhanced safety. These batteries feature an open circuit voltage of 4V, a discharge capacity of 500 mAh (20 mA at 2.8V RT), and the ability to handle 5A continuously and 15A maximum pulses.

3U VPX Graphics Board

WOLF Advanced Technology’s (Ontario, Canada) new 3U VPX board, the VPX3U-GTX850M, is developed using NVIDIA’s GeForce GTX-850M – CUDA powered 28nm GM107 GPU – which is clocked at 862MHz and has 5 Streaming Multiprocessors for Maxwell (SMMs) each housing 128 Arithmetic Logic Units (ALUs) for a combined total of 640 Shader cores for CUDA or OpenCL parallel processing. An additional 40 Texture Mapping Units and 16 Render Output Processors, with a massive 2MB L2 cache and 2GB of GDDR5 memory – running a 128-bit interface – offers DirectX 11.2 or OpenGL 4.4 rendering capability per watt. The GPU also supports the sixth generation PureVideo HD video engine (VP6) for hardware decoding of MPEG2 and H.264 compressed video at resolutions up to 4K.

Trimming Wiring Harnesses Becomes Design Focus

Wires and cables help design teams add electronic features and functions, but networks and wiring harnesses add a fair amount of weight while their connections can be the cause of failures. That’s prompting developers to examine ways to reduce the size and weight of wires and cables. Read more at http://articles.sae.org/13419.

Open Generic Avionics Architectures and Distributed Processing Using Ethernet and VPX

The backplane and hardware module standards help to increase part commonality and the reuse of components in different system architectures and applications, but this is only one part of the system design challenge. While the specified footprint, backplane format, and electrical signal characteristics help the design of modular hardware and open architectures, they still tell very little about how modular (and unambiguous) the interfacing among functions and their interactions are. This aspect is covered at the system integration (network) layer.

Small Form Factor Strategies for Military Embedded Systems

The proliferation of unmanned military vehicles tasked with critical communications and radar requirements drives the need for powerful data acquisition and signal processing products that must fit into increasingly tighter spaces. New industry standards meeting these needs offer smaller circuit boards and enclosures, optical gigabit serial links, and advanced thermal management strategies. With new resources found in the latest processors and FPGAs, system designers can now create powerful, compact systems surpassing performance levels achievable only a few years ago.

Power Management for the Electric Taxiing System Incorporating the More Electric Architecture

With airlines increasingly directing their attention to operating costs and environmental initiatives, the More Electric Architecture for Aircraft and Propulsion (MEAAP) is emerging as a viable solution for improved performance and ecofriendly aircraft operations. An electric taxiing system was developed that does not require the use of jet engines or the auxiliary power unit (APU) during taxiing, either from the departure gate to takeoff, or from landing to the arrival gate.

Implementing Interconnected Generation in Future Civil Aircraft

In addition to providing thrust, the engines on conventional civil jet airliners generate power for onboard systems and ancillary loads in the form of pneumatic, hydraulic, and electrical power. There is a move to begin replacing mechanically, hydraulically, and pneumatically powered aircraft systems with electrical equivalents, towards the ultimate goal of achieving the All-Electric Aircraft (AEA).
