Apparently all those pot-holes that make your car go up and down are just wasting valuable energy that could power such things as street lamps and traffic lights. An English inventor has developed ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...

It’s not always easy to design a ramp generator whose ramping frequency can be changed without manipulation of capacitors or inductors. Many ramp circuit designs are available, but they may not be ...

The Road Ramp generator is more effective than wind turbines and gives a second bang, so to speak, from what is presently wasted petrol. Optimally installed in ramps where the vehicle has to slow ...
