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: A front light module includes a light guide sheet and a light bar. The light guide sheet has two light receiving laterals, a fold line, a first pattern area, and a second pattern area respectively located on two sides of the fold line. One light receiving lateral is protruded to form first taper sets, and the other is protruded to form second taper sets. The second pattern area is superimposed on the first pattern area, and the first and second tapers set are engaged and coplanar to form a light incident surface after folding along the fold line. The light bar provides light toward the light incident surface, the first pattern area is lit by the odd positions of the light bar via the first taper sets, and the second pattern area is lit by the even positions of the light bar via the second taper sets.

Abstract: An automatic material changing and welding system for stamping materials includes a welding transfer sliding table and a welding platform. The automatic material changing device further includes a feeding system. The feeding system includes a double-head uncoiling machine, an automatic feeding machine and a flattening machine. The automatic material changing device is used for automatic feeding for a stamping machine. The system triggers a material changing signal through a sensor to control and integrate the welding transfer sliding table and the welding platform to act to execute a welding procedure, so that the stamping materials are in welding connection with new and old coiled materials through a welding connection plate to realize continuous production operation of an automated stamping production line.
