The dual-polarized patch antennas designed by CityU are compatible with L-shaped probes, which are also invented by CityU. The L-shaped probe is connected to the input port, and part of it is parallel to the patch. The isolation enhancement technique inherent in this invention can reduce the strong .....

This technology is a dynamic output compensator that can significantly improve the dynamic response of voltage regulators. The key advantage of the compensation method is that it is not necessary to redesign the power conversion stage and controller existing in voltage regulators. It only requires .....

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.....

Speed sensors are customarily used to detect the speed of power electronic driven motors, but that speed sensors could render the motor drive system unreliable. However, there are very few detection devices other than speed sensors that can generate readings when the motor drives are in a resting mo.....
