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 .....

With this new technology, a user can create paintings on a digital canvas using a pointing device. The images generated are expected to exhibit hand-drawn qualities. The depth map of the painting can be controlled, and that 3D images can be created. Watercolour paintings, graffiti paintings, and cal.....
