Improved Contactless Rotary Position Sensing

Traditional Hall-effect sensors measure the magnetic field perpendicular to the surface of the semiconductor chip. By integrating a planar magnetic disk parallel to the integrated circuit's (IC's) surface, the resulting flux concentrator allows measurements parallel to the surface and provides several advantages.

Light Matters: The Unsung Heroes of Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
