SMART LED FLASHLIGHT – a tiny personal emergency Light sensing LED flashlight.
How it works: The flashlight turns on automatic for 60 seconds when it senses that the room is dark enough. To turn on manual light for additional 60 seconds you need to push the RST button. The Light sensing LED Flashlight is invaluable for emergencies such as power failures or blackouts. Step 1: The Flashlight

Sensing current on the high side
As EDN’s Design Ideas editor, I see a range of design submissions, from good, to not so good. A recent DI I turned down for several reasons included a high-side current sense circuit with implementation problems. This got me thinking about the different ways to accomplish current sensing on a voltage rail. At their heart,

Qi introduces predictive sensing
Quantum Interface (Qi) of Austin, Texas has come up with a predictive navigation interface which is responsive to motion, analysing the speed and direction of any input to determine user intent. It is offering beta versions of an app using technology. When a user moves toward a menu selection with a finger on a touchpad,
