Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. Using a headphone wire as an FM antenna The earliest portable AM/FM portable radios used two antennas: an internal long wire wound on a ferrite core for the lower-frequency AM band (550-1600 kHz), and a “whip” antenna […]
Although there are more than a dozen symptoms of premature wear and impending failure for V-belts — ranging from visible damage to audible noise — there are a few key ways that these friction-based belts can fail during operation. To help users determine the root cause of a failure or signs of potential failure, V-belt […]
With each discrete step that a stepper motor makes, the inertia of the system causes the motor to slightly overshoot (or undershoot) the intended step angle. The motor then oscillates, or “rings,” until it finally settles at the commanded position. If the frequency of these step-by-step oscillations is at or near the motor’s natural frequency, […]
Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. Providing DC power to an antenna amplifier via an RF coaxial cable In most applications where the antenna is located at a distance from the radio receiver front end, it is desirable or necessary to add a […]
COMSOL, the maker of the COMSOL Multiphysics simulation software, has opened registration for COMSOL Day: Version 6.0, a series of online events held around the world for the computer-aided engineering (CAE) market. Starting on January 27, there will be four events to introduce COMSOL Multiphysics version 6.0 to a global, multiphysics simulation community of innovators […]
Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. A classic engineering objective is to figure out a way to get one set of wires to provide a second function at little cost. This second part in the series looks at phantom power in more detail. […]
Recirculating Slide Guides Recirculating slide guides excel in three areas: applications needing longer strokes, designs with space constraints and configurations where cost is a primary concern. Because of the unique design, travels are only limited by the maximum rail length of each profile size.
As the impact of climate change and land use continue to harm aquatic environments, it is becoming increasingly important to measure and monitor changes in water quality. When Dublin City University (DCU) Water Institute was developing its new mobile lab technology to help predict future changes in water quality, it turned to precision drive and…
ICC 2021 Discover Gallery finalist, Perceptive Controls, talks about their continued success with the Waterford, MI Department of Public Works In February of this year, we looked at a pioneering MQTT Sparkplug project at the Department of Public Works in Waterford Township, Michigan. Thanks to the work of system integrator Perceptive Controls, Waterford’s project went on to…
In cement, mining, fertilizer and industrial aggregate applications, chain bucket elevators are used to transport bulk materials vertically. Demanding environments like these often challenge system reliability and require unique, innovative chain solutions. Balancing adequate strength with features that effectively defend against corrosion and abrasion can often be a challenge but is certainly feasible and should…

A microdisplay breakthrough from University of Cambridge spin-out Porotech is set to accelerate the long-awaited commercialization of augmented reality (AR) glasses. The micro-LED pioneer has created the world’s first microdisplay based on native red indium gallium nitride (InGaN) – with an active area of 0.55 inches diagonally and a resolution of 960×540. Until now, it…
Looking for a positive year ahead After a rough 18+ months, I think we’re all ready for positive news in the coming year. And 2022 is showing some upward trending signs. I recently attended an economic outlook talk given by Jim Meil of ACT Research Co., LLC, presented by the NFPA, and came away feeling…
