Wire Springs versus Machined Springs A Comparison

The first question generally asked about Machined Springs is how they compare with Wire Wound Springs. Commencing with this question, this review of Machined Springs will proceed. Wire Springs appeared early in the Industrial Revolution. They established their value immediately, and have not wavered from that most useful course. Certainly, enhancements in materials and manufacturing have been forthcoming, but the basic concept has not changed much. Spring wire coiled hot or cold with ends configured within the limits of coil wire has proven to be a very cost effective, industrial tool that exhibits elasticity within the bounds of known, engineering understanding. Uses range from deep ocean applications to man's reach into the universe. Finding a modern day device large or small, that does not benefit from elasticity, and particularly that provided by Wire Wound Springs, is a rare find.

Miniaturization of Medical Devices: The Future of Patient Care

TE Medical’s Vitaliy Epshteyn will discuss recent trends in the medical device industry towards customer-driven electronics. He will share cutting edge technologies to support these trends, and present case studies of product innovations in Ultrasound, Surgical, and Interventional applications. Many of these innovations enable device miniaturization while enhancing overall functionality. Evolving medical devices into miniature form is vital to the future of patient care. As devices shrink in size, the procedures become less-invasive, allowing patients to heal more quickly. Miniaturization is an advanced solution that positions OEMs to compete in today’s medical device industry.

Particle Tracing Simulations with COMSOL Multiphysics

The Particle Tracing Module extends the functionality of the COMSOL Multiphysics environment for computing the trajectory of particles in fluids and electromagnetic fields, including particle-particle, particle-field, and fluid-particle interactions. The particles can be subjected to a wide variety of forces, such as electrical, collisional, drag, and thermophoretic forces. This webinar introduces particle tracing for applications such as erosion, etching, mixing, filtration, mass spectrometry, ion optics, and beam physics. The webinar includes a demonstration and will end with a Q&A session.

Piezo Engineering Tutorial

1.0 The Direct and Inverse Piezoelectric Effect In 1880, while performing experiments with tourmaline, quartz, topaz, cane sugar and Rochelle salt crystals, Pierre and Jacques Curie discovered that when mechanical stress was applied to a crystal, faint electric charges developed on the surface of that crystal. The prefix “piezo” comes from the Greek piezein, which means to squeeze or press. As a result, piezoelectricity is electrical charge that is produced on certain materials when that material is subjected to an applied mechanical stress or pressure. This is known as the direct piezoelectric effect.

Magnetic Levitating Gear Has No Touching Parts

Researchers are developing a new transmission mechanism, with no touching parts, based on magnetic forces that prevent friction and wear, and make lubrication unnecessary. It can be applied in space travel and exploration, but has also been adapted for use in other areas such as the railroad and aircraft industries.
