  • Publication number: 20080275320
    Abstract: We present an optical probe arrangement that surrounds blood in a receptacle. It comprises LED's and light detector arranged to overcome the variations when the receptacle is translucent medical tubing and the like. Also, a signal processing algorithm is used to average signals from a plurality of light detectors, to further enhance results when measuring hematocrit. The invention makes it possible to add the feature of hematocrit measurement into dialysis system without major alterations to the dialysis machine or transport tubing.
    Type: Application

  • Publication number: 20020087997
    Abstract: A method of storing information in a multimedia integrated receiver decoder arranged to be used with the Multimedia Home Platform standard. First, user commands input to the integrated receiver decoder are interpreted (110). Then, the user commands are collected (120) and saved (130) as data items in a database. Finally, the data items are made accessible to computer applications run on the integrated receiver decoder by means of an Application Program Interface (140). This makes it possible for agents to get information on viewing and box using habits for all channels.
