The invention concerns a method and apparatus for controlling the output phase of a voltage controlled oscillator (VCO) for use in antenna arrays for receiving radio signals. Such arrays can converge energy, receive signals, and reject interference. Beam-forming techniques using phase shifters are u.....

The invention relates to a method of manufacturing ballasts for high voltage discharge lamps. The method provides the passive LC ballast with an inductance and capacitance derived from a non-linear model. The purpose is to ensure that the lamp operates at a pre-determined lamp power. The ballast is .....

The panoramic stereo imaging system is capable of providing 3D visual information in all directions with depth information. The system, installed with a camera coaxially combined with a fisheye lens and mirror, provides stereo vision over a 360-degree horizontal field of view and the entire vertical.....

In smart systems, sensors play an important role because they form the link between mechanical and electronic systems. Magnetic sensors are widely used to measure mechanical quantities because they allow contact-less and, therefore, wear-free measurements. In particular, magnetoresistive sensors can.....
