Seiko Instruments' Hall Effect Sensor IC's offer
bipolar or unipolar high speed detection and high sensitivity.
The output voltage changes when the Hall IC
detects the intensity level of flux density and a change in polarity. Using
Seiko Instruments' Hall Effect Sensor IC's with a magnet makes it possible to
detect opening/closing and rotation in various devices. High-density mounting
is possible by using the small SOT-23-3 or SNT-4A packages.
Built-in chopper-stabilized amplifier

Halloween isn’t just a time for creative costumes. Thanks to the element14 online design community, the holiday this year also brings us a number of creative electronic device design ideas aimed at making your Halloween party a unique experience.
On April 15, 2010, President Barack Obama gave a major speech at the Kennedy Space Center in Florida, announcing that the US would send astronauts to Mars by the mid-2030s. But in order to do so, NASA would first need to ramp up its capabilities through missions directed toward "a series of increasingly demanding targets," i.e. asteroids.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
