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.....

Transformers are used for energy and signal transfer and for providing electrical isolation. CityU researchers have developed a coreless PCB-based transformer that does not require a transformer core, thereby reducing production cost and simplifying the automated manufacturing of transformers. The i.....

Novel methods for improving compression efficiency by compressing and encoding images are proposed in this patent. The image to be compressed is partitioned into blocks, which will then be individually analyzed to determine suitability for discrete wavelet transform pre-processing. The blocks are al.....

Patients with patellofemoral pain often use knee support braces or sleeves to reduce the friction of knee joints. However, the knee support braces or sleeves may result in reduction in power generation at the joints and limit active flexion. To address the problem, the inventors developed a superela.....
