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.....

This invention describes a method of installing an active barrier as an adaptor onto a projection screen for displaying normal 2D or multiple 3D images. The converted projection screen can switch in real-time between normal 2D and 3D modes. The control signal embedded in the image is detected with o.....

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 .....

The dielectric resonator antenna (DRA) has received increasing attention in recent years. It has a number of advantages including its small size, light weight, low cost, ease of excitation, and relative wide bandwidth as compared with the patch antenna. Also, it is a volume device that offers the de.....
