Axial mode helix antennas are used as RFID base station antennas but the number of winding of helix antennas are at least 10, making them too high for use as base station antennas. To address the problem, an integrated wire elliptical helical antenna with novel cuboids dielectric resonator loading f.....

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.....

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 technology complements the on-chip monitoring of cellular reactions by exposing cells, isolated in a sandbag structure, to different concentrations of analytes or drugs in a one-step operation. The tapering microchannel structure controls the concentration and dosage of the analytes. Another maj.....

High-order filters, capable of increasing the efficiency of converters, depend on advanced control algorithms to reduce multiple resonant frequencies, but that such algorithms often require precise information about the component parameters of the converter’s output filters. To capture the parameter.....
