  • Patent number: 11491305
    Abstract: A method for producing a catheter includes inserting a temporary mandrel into a catheter tube, followed by preshaping a FPCB in a round hollow cylindrical shape and position it on the catheter tube. Then a shrink tube is positioned around the FPCB on the outside of the catheter tube. The assembly is preheated to the point that the shrink tube has fully contracted and directly contacts and closes the FPCB around the catheter tube. Then the assembly is heated above the melting temperature of the catheter tube to reflow the catheter tube material around the FPCB inside the shrinking tube. After a resting period to allow solidification of the assembly material the mandrel is removed from the inner lumen of the re-solidified catheter tube, and finally the shrink tube is removed.

  • Patent number: 8120321
    Abstract: A device for balancing a plurality of at least two batteries or cells of a multicell battery comprises a multicell battery and a battery management system with a balancing circuit. Thereby all individual battery cells are connected to the battery monitoring system, wherein the battery monitoring system measures single cell voltage as well as the battery temperature and the current. The battery monitoring system is able to discern the lowest cell voltage and to discern a number of cells having a voltage higher than a determined maximum allowable voltage, which will be balanced until the charge imbalance decreases to an acceptable amount. The battery management system is active during charging and discharging of the multicell battery and the thresholds vary with the state of the battery.

  • Publication number: 20070133839
    Abstract: A method for transmitting a coded information to a user via a graphical display. The method comprises the step of obtaining coded information by a scanner, which has to be positioned near the graphical display. The coded information is transmitted to a number of code points that are arranged in the direction of the fast refresh rate of the display.
