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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
