Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

Abstract: The present invention provides a multi-touch position tracking technique and an interactive system and a multi-touch interactive image processing method using the same. In the present invention, a light guide element is designed to comprise frustrating structures to frustrate total internal reflection (TIR) so that the light beam therein can be dispersed to form a dispersed optical field distribution. The dispersed optical field is used to respond a physical relation between an object and the light guide element.

Abstract: The present invention provides a method and device for optically extracting discrete features of an object. With this method and device, small regions of interest or features within a relatively large object are optically extracted and collated into a single, condensed image. The condensed image contains all of the features in the original object, but not the parts of the object that are between the features. Thus, the optically extracted features can be viewed at high resolution, but in a limited field of view. Examples of objects that may be optically extracted according to the invention include spots of biomaterial on a biochip, material in wells of a microtiter plate, etc. In addition, this device and method can be used for non-planar objects. In this case, the device and method allow simultaneous visualization of spatially separated features on a surface of a 3-dimensional object.
