    摘要： A self-opening/closing umbrella includes a central shaft unit having an improved structure. The central shaft unit forms a raised channel on one side of a third shaft segment and a pulley is pivotally mounted to a lower portion of the raised channel. A second shaft segment has a top to which an internal plug including a pulley is fixed and includes a first pull rope having an end fixed to a bullet-head member and an opposite end extending upward to warp around the pulley of the internal plug, projecting through a sideway slot, extending downward to wrap around the pulley inside the third shaft segment for upward extension to fix to a top end of the third shaft segment. A second pull rope has an end fixed to the internal plug and an opposite end extending across a top cap to project outward to fix to the runner.

    摘要： A system for determining the concentration of an analyte in at least one body fluid in body tissue comprises an infrared light source, a body tissue interface, a detector, and a central processing unit. The body tissue interface is adapted to contact body tissue and to deliver light from the infrared light source to the contacted body tissue. The detector is adapted to receive spectral information corresponding to infrared light transmitted through the portion of body tissue being analyzed and to convert the received spectral information into an electrical signal indicative of the received spectral information. The central processing unit is adapted to compare the electrical signal to an algorithm built upon correlation with the analyte in body fluid, the algorithm adapted to convert the received spectral information into the concentration of the analyte in at least one body fluid.
