Part 1 of this article looked at the classic, highly refined, mature gyroscope-based IMU used for the Apollo moon mission; this part looks at the very different technologies which have largely replaced it. Gyro-based IMU: obsolete, or not? Inertial navigation relies on a stable platform with an orientation which is fixed in space and maintains […]
Inertial Measurement Units: The hidden key to Apollo success, now a MEMS device (Part 1)
Transforming the gyroscope from a child’s toy to a precise guidance system for the Apollo moon landings demanded the ultimate in analytical, engineering, and manufacturing effort: now, MEMS-based units have largely replaced these gyro-based systems. With the 50th anniversary of the Apollo manned lunar landing on July 16, 1969, 9:32 AM GMT-4, there have been […]
Part 3: Winning with a sustainable PDC management process in embedded systems design: implementation
In part 1, we presented an overview of the product life cycle (PLC) and product development cycle (PDC), as well as the difference between the two. Part 2 explained in detail the 12 steps of the product life cycle (PDC). In this final part, we offer some practical suggestions on PDC implementation. The secret to […]
Part 2: Winning with a sustainable PDC management process in embedded systems design – 12 steps
In part 1, we provided an overview of the product life cycle (PLC) and product development cycle (PDC), noting their distinct differences. In this second part, we will explain in detail the 12 steps of the product development cycle (PDC). Figure 1 shows the typical flow chart of a PDC management process and the 12 […]
Winning with a sustainable PDC management process in embedded system design
This is the first in a three-part tutorial series explaining how to implement the product development cycle process. Nearly everyone knows Microsoft Excel. Fewer know Lotus 123, and almost no one remembers VisiCalc, the first version of a spreadsheet computer program for personal computers, which ran on the Apple II. There have been a few […]
Simplifying product returns through device security
by Oivind Loe, Chief Technology Officer, Sipsby.com, and Josh Norem, Staff Systems Design Engineer, Silicon Labs Product returns for Internet of Things (IoT) devices can be challenging. On the one hand, connected the device should be locked down as much as possible when going out to the field. On the other hand, when a device […]
Strengthening IoT with smart cards
With the Internet of Things (IoT), industries are relying on connected devices that can interact with each other and also with processes and personnel thus helping businesses meet their goals efficiently. IoT enabled devices are being successfully used in multiple industries like manufacturing, construction, logistics, agriculture, etc. and helped to optimize assets, conserve resources and […]
What could happen if there’s an EMP or solar superstorm? Part 2
Read Part 1 here. In 2006, the creators of the TV series Jericho imagined how nuclear detonation would affect a small Kansas town. Large solar-based EMPs have been documented. In 1859, a solar storm dubbed the Carrington Event hit the Earth’s magnetosphere. One of the largest solar storms on record, the CME in 1859 caused […]
What happens to an MCU if there’s an EMP or Solar Superstorm? Part 1
An Electromagnetic Pulse (EMP) is an impulse or blast wave that’s generated by geomagnetic activity due to solar flares, solar storms, solar superstorms, or the detonation of nuclear weapons. The horrible truth is that an EMP can wipe out electronics by inducing inductive coupling on traces, wires, or any conductive media within hundreds to thousands […]
How to structure SystemVerilog for reuse as Portable Stimulus
by Matthew Ballance, Mentor, a Siemens Business In our previous article, The Nuts and Bolts of Verification: Recasting SystemVerilog for Portable Stimulus, we described how verification teams can jumpstart portable stimulus test description creation using existing SystemVerilog constructs and principles. Now, switching from analogy to idiom, we’ll dive into the “nuts and bolts” of how […]
