  • Patent number: 11944412
    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.

  • Publication number: 20130260479
    Abstract: A detecting device is used for detecting existence of target biomolecules in a specimen with use of antibody complexes labeled with fluorescent molecules. The detecting device includes a capture member coated with capture antibodies for immobilizing the antibody complexes on the capture member when the target biomolecules exist in the specimen, a light emitting unit emitting a beam for exciting the fluorescence molecules to generate a fluorescence signal, and a signal processing unit for receiving the fluorescence signal and determining existence of the target biomolecules in the specimen based upon receipt of the fluorescence signal.

  • Patent number: 5594926
    Abstract: The present invention provides a hard drive accelerating system (32) that substantially improves the hard disk data transfer speed in a computer. The accelerating system decomposes a traditional CPU IO command to read or write a hard disk drive (18) into two separate tasks that can be executed concurrently. A read buffer (40) and a write buffer (42) are used to link the two tasks. A state machine (48) generates consecutive IO read cycles to fetch data from the hard drive to the read buffer while the CPU executes IO commands to retrieve data from the read buffer. A programmable hardware register (49) adjusts the hard disk IO cycle time to achieve maximum compatibility with different hard drive speeds.
