Piezoelectric ceramics, less expensive than quartz, have wide applications in medical diagnosis. The invention relates to a piezoelectric resonator that detects the presence and concentration of target markers in samples by measuring the resonator frequency changes brought about by the markers. The .....

This invention involves a kind of sensor used to detect markers in samples. The sensor uses high-frequency piezoelectric ceramic oscillator chip (500kHz-1GHz) as the inductor to detect the change of resonance frequency.This invention involves a method used to detect and evaluate the number of one or.....

The invention enables a user to create images with a hand drawn appearance on a digital canvas by using a pointing device. A depth map of the painting can also be generated. The painting and its depth map can be juxtaposed to form an integrated image which can be displayed as a 3D image on a 3D or a.....

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.....
