This rugged board is made to handle harsh environments in defense, aerospace and space applications. It offers several I/O capabilities, including ARINC-429, analog-to-digital, digital-to-analog, audio and discretes. It's perfect for general-purpose airborne applications like manned and unmanned aerial vehicles and helicopter platforms, with a new single-slot C437 accommodating I/O for a large number of sensors and actuators. There are independent power and ground domains for each of the C437's analog, digital and discrete I/O sections, isolating each signal from the other, maintaining signal integrity and minimizing cross-coupled noise. The board's new I/O components include 24 AEEC-compliant ARINC-429 channels that support both high and low-speed configurations, 60 single-ended discrete inputs, 2 differential inputs and 41 single-ended discrete outputs, plus four opto-isolated, -10 to +10V, 16-bit differential analog imputs and four -10 to +10V differential analog outputs. The board can store and play back prerecorded audio messages through an MP3 player with stereo audio output and dedicated Flash and SRAM memory. The C437 can decode and play MP3+V, WAV, PCM and MPEG 1 & 2 audio layer 3 files, plus run-time messages and uses a VMEbus bridge in a FPGA logic device, offering slave VMEbus capabilities, and support for A32/D08/D16/ D32 data transfer to and from any standard host board. The host is free to perform other tasks too, as the FPGA logic device offers full autonomous control over onboard functions. The C437 works well with moderately-powered systems, using only 14W of power. It comes in both conduction and air-cooled models, and is fully compliant with IEEE 1101.2. It has a metal thermal frame for vibration and shock control, plus added heat paths for less thermal impedance. The board has built-in self tests and integrated RTOS drivers, which include VxWorks and Integrity, for control/status and access to all the C437's I/O modules from the VMEbus host card. Other popular real-time operating system drivers are available by request.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
UK researchers have come up with a method for machining aerospace-grade, carbon fiber-reinforced composites, along with high-strength aerospace alloys, using an ultrasonically assisted machining device. It also works on high-strength aerospace alloys.
