Ultra Low Power LCD Indicator -  This circuit serves as an ultra-low power replacement for multiple LED on-off indicators. It also has the advantage of being easy to read in full daylight. With the parts shown, it is possible to display four bits of information…. [G. Forrest Cook]
Ultra Low-Cost Programmer for AT90s Family -  With this programmer you can program AT90S1200,  2313,  2323, 2343, 4414, 4434, 8515, 8535….(electronic circuit added 4/05)
Ultracompact LCD Backlight Inverters -  AN81 Linear Technology It has become desirable to fashion laptop computers with large area screens, leaving little room for the display's backlight inverter electronics. Miniaturization limitations of high voltage magnetic transformers impose limits on achievable space reduction. Another voltage step-up technology, piezoelectric transformers,.....
Under Sampling Extends utility of Digital Scopes -  04/09/98 EDN-Design Ideas.....By undersampling the input signal, you can use a digital oscilloscope to digitize and display or collect signal data of even RF and IF signals. To sample a signal without aliasing, you must use a sampling rate that satisfies the relationship.....several circuits included, scroll the find this one..... [Design Idea by Robert J Inkol, Defence Research Establishment, Ottawa, ON, Canada]
