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.....

            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.....

            The system combines a three-axis motion control and an amplifier as a high integrated model. It comprises an upper motion controller board, a middle amplifier board, and a lower heat sinking board. Two digital control loops of outer position loop and inner current loop are designed for four KHz and .....

            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.....

            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.....
