A survey of senior-level, experienced Industrial Internet of Things (IIoT) decision-makers and influencers in the manufacturing, oil and gas (O&G), and transportation industries confirms that IIoT has progressed beyond hype to widespread use. Eighty six percent of participants in the Bsquare 2017 Annual IIoT Maturity Survey have adopted IIoT solutions and 84% believe their solutions are very or extremely effective.

Commercial trucking, agriculture, and construction businesses know the challenges of relying on heavy-duty vehicles and equipment for day to day operations and the cost of maintenance over a vehicle's lifetime.

Rochester Electronics documents a design replication process that develops form, fit and functionally equivalent devices which falls under a DO-254 minor change classification.

Many applications, such as government, military, medical, and embedded system designs struggle with the typical computer product lifecycles. Most commercial-grade computers have a 1-2 year lifecycle before the computer is EOL (End of Life). There are also very few assurances that the rack mount computer is properly revision-controlled so you can rest assured that nothing inside the computer changes the form, fit, or function. Engineers spend a lot of time and energy determining the right specs, validating the product, getting industry certifications, and then finally getting to full production...and in many cases this spec, test, and certification process can take longer than the computer’s 1-2 year lifecycle.

The inexorable demand for bandwidth fuels the need for agile systems throughout data networks. Even satellite communications are undergoing transformative digital developments. Innovative architectures supported by new, ultra-wideband (UWB) data convertors are helping boost both their economics and data throughput. Read this white paper from Teledyne e2v to find out just how these UWB data converters are affecting payload system design choices to boost economics and delivering new price points.

The car radio has evolved from a cassette player to a state of the art entertainment system, keeping the driver and passengers connected on the go. The entertainment system brings a design challenge in that communication and broadcast standards have to coexist within a small area in the dashboard of a car. Since the frequencies defined by the RF standards are in close proximity, it is very important that the frequencies coexist and since multiple standards need to be supported in the single assembly, RF modules are placed next to each other on the assembly line. Other than testing the entertainment center in the car, the antennas inside the car are subjected to cross-coupling effects with passengers mobile devices. To ensure the RF performance of the infotainment system, all of these scenarios need to be thoroughly tested. This application note highlights some of the RF measurement challenges and introduces equipment that is required for relevant RF characterization of car infotainment devices.

There are many places one can go to get an outline on the pros and cons of different methods for enclosure cooling. Although we will briefly touch on them here, this is really an in-depth article on how to choose a Peltier (thermoelectric) air conditioner, once you have committed to the technology.

In electric and hybrid vehicle applications, electrical systems are often pushed to their limits. Aggressive current pulses, combined with high temperatures and vibration profiles, push the limits of electrical system reliability. When selecting an over-current protection device (OCPD), care must be taken to account for these complex variables while still providing a system that is safe and reliable. This article will discuss five critical and often overlooked factors in OCPD selection in EV applications in order to ensure safe and reliable system performance.

High-voltage power supplies drive a broad range of applications across diverse segments, including semiconductor, scientific, medical, industrial, and more. Designed to deliver stable supply voltages at 50 V and up, the power supplies, comprised of sophisticated components and specialized materials, must carefully manage the high voltages and associated effects, for example, corona and arcing. For systems developers choosing standard high-voltage power supplies, the specialized nature of high-voltage power calls for a power supply selection process that reflects the unique characteristics of the high- voltage power supply and its operation.

RF and microwave components deployed in space flight applications can experience hundreds of degrees of temperature variation, massive amounts of radiation, and can be expected to operate at an elevated level for sometimes decades. The demands of operating in a space environment bring many unique challenges and unforgiving reliability requirements; therefore, designing passive components to meet these rigorous operation criteria necessitates a high level of design expertise, qualifications/certifications, and testing capability.
