Selecting Miniature Motors for your Medical Devices

The creation of small, portable infusion pumps opened a new chapter in medical care. A patient can receive carefully metered and timed doses of medicine, without requiring a visit to the medical practitioner, allowing life to be less restrictive. Ambulatory pumps have been developed to deliver insulin, nutritive supplements and anticancer drugs.

The Sun’s Surface in Stunning Detail

Located on the Canary Island of La Palma, the Swedish 1-meter Solar Telescope (SST) is the world’s leading facility for high resolution observations of the Sun. It is operated by the Institute for Solar Physics (ISF), which is part of Stockholm University’s department for Astrophysics. Research at the institute primarily aims to gain knowledge about the outer layer of the solar atmosphere, which is dominated by magnetic fields. How do magnetic fields arise? How are they formed and ultimately destroyed or removed from the solar surface? How do they affect the Sun‘s outer atmosphere? How do they give rise to solar storms and the radiant energy that the Sun emits?

The Ultimate Shaft-To-Hub Connection

Polygon Shapes - Multi-Faceted Problem Solvers Kinematically ground polygonal shapes have been used as drive connections for more than 45 years. What is now referred to as Polygon Systems was developed by Fortunawerke, Stuttgart, West Germany, who patented a grinding machine capable of producing matched polygonal shaft and bore diameters.

Multi-Material, Multi-Color 3D Printing Creates New Possibilities

Major advances in multi-material, multi-color 3D printing technology are driving a fundamental shift in how people are going about designing, engineering, and manufacturing products. The advanced capabilities of state-of-the-art, multi-material, multi-color systems such as the Objet®500 Connex3™ from Stratasys, are opening up many new applications. Making this possible is the Connex3’s ability to produce high-resolution, highly detailed, and functional parts from even the most complex designs. The Connex3 is the world’s first 3D printer that combines multiple materials and colors in a single build. With it, users can simultaneously tailor a part’s material properties, create sharp and well-defined boundaries between different materials, and achieve a sophisticated look and feel that closely mimics a finished product’s aesthetics. This white paper explores the technology at the heart of the Connex3’s performance, and shows how one customer is benefitting from it in many different ways.

Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems

To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable. www.princetel.com
