The Rexing V1 is a simple wedge-shaped dash camera that films in a 1080-line progressive scanning format. The lens is made of six glass layers and is fish-eyed to capture a 170° view of whatever it sees. There’s also a built-in vibration sensor, called a G-sensor in the promotional literature, that automatically locks any files recorded during a moment of unusual … [Read More...]

8-bits and counting: 8-bit MCUs are still going strong
Microcontroller units (MCUs) never stop evolving; a more functional, featured MCU follows every model. Embedded systems have grown with continually growing MCU technology, yet there are many traditional MCUs that are still selling in high volumes. Atmel 8051 is one of those legendary MCUs which have developed a considerable demand in the market. The Atmel […]
Filters, Part 1: Analog, switched, and digital filters
Filters are essential functions in most circuits and systems; as frequencies extend into the multi-GHz range, surface acoustic wave (SAW) and bulk acoustic wave (BAW) filters are needed to meet the design objectives. An engineer I worked with (and whose name I have forgotten) once remarked to about electronic filters (and he was serious): “like […]
MRI, Part 2: Historical development (and lawsuits)
The modern MRI system is an amazing blend of diverse technologies, based on the realization that a small but critical aspect of the spin of hydrogen nuclei could be leveraged to provide a safe, non-invasive way to see inside a human body. Part 2 of this FAQ looks at the physics and other advances that […]
Working with higher voltages, Part 2: Voltage multipliers
In part 1 of the FAQ, we looked at techniques for a modest amount of boosting of lower voltages, as well as for increasing a voltage to a much higher value. The techniques discussed thus far boost and thus multiply the voltage, but what are called voltage “multipliers” usually give push voltages to much-higher values. […]
Working with higher voltages, Part 1: Voltage boosters
Whether for efficiency or due to the device physics, many applications require voltages ranging in the tens, hundreds, or even thousands of volts; the circuits which produce these voltages start with basic charge pumps and extend to voltage multipliers with simple schematics but many subtleties. Lower-voltage circuitry is the trend, with ICs and designs operating […]
Magnetic resonance imaging (MRI), Part 1: How it works
The modern MRI system is an amazing blend of diverse technologies, based on the realization that a small but critical aspect of the spin of hydrogen nuclei could be leveraged to provide a safe, non-invasive way to see inside a human body. Magnetic resonance imaging (MRI) is an extraordinarily valuable and vital tool for non-invasive […]
How to create and run reusable register-test models
by Matthew Ballance, Mentor, a Siemens Business Register tests are a very useful smoke test at all design levels — from IP to subsystem to SoC. While the built-in register-test sequences in the UVM library are useful at the IP level, capturing register-test intent in a PSS model makes register-test functionality portable from the IP […]
What you need to know about buzzers – reviewing the basic types and technologies
Bruce Rose, Principal Applications Engineer, CUI Inc A buzzer can provide a cost-effective yet intuitive aspect to the user interface of a wide variety of products, such as a home appliance, security panel, door-entry system or computer peripheral. Usually the choice is between either a magnetic or piezoelectric type. It should be an easy decision, […]
Basics of signal jamming
Discussions of signal jamming were once largely confined to electronic warfare forums. But with the rise of autonomous vehicle technology, jamming has become a mainstream topic. Thus is now pays to know a few basics about both the test setups necessary to gauge resistance to jamming techniques and the principles of signal propagation. Many of […]
