  • Publication number: 20240001047
    Abstract: An infusion liquid heating and flow-velocity-monitoring system for clinical use is provided. The system includes a dynamic heating module, a measurement and analysis module for average velocity in infusion tubes, a velocity adjustment module, an alarming and automatic clipping module, a mobile-phone-computer remote monitoring module, an operable shared module, and a micro control module. A method of determining average velocity on a cross section of a tube according to a solution to Fourier series in a dynamic thermal dispersion equation of a steady flow in the tube is provided. Moreover, functions including monitoring infusion rate, automatic heating, monitoring whether infusion fluid in the infusion tube is empty, and automatic clipping and closing of the tube for preventing blood backflow, etc. are achieved. Lastly, specific applications developed which is connected with mobile phones by 5G network, Bluetooth and WIFI are used to display status of the infusion fluid.

  • Publication number: 20080188678
    Abstract: The invention provides generally a new type of organic electrochromic Near Infrared (NIR)-active materials capable of absorbing and attenuating the light in the NIR region around 1550 nm and forming thin films on electrodes for variable optical attenuator (VOA) applications. They have utility in planar VOA devices. The materials are ruthenium complexes. Unsymmetrical complexes having two different substituents are disclosed, where one substituent is more electron-donating than the other. Complexes which are dimers or trimers (symmetrical or unsymmetrical) are disclosed, as are polymeric complexes. Crosslinked polymeric complex films are also disclosed.

  • Patent number: 6894169
    Abstract: A non-linear chromophore is obtained by reacting a picolinium halide having a desired functional group (preferably —OH) with a lithium TCNQ adduct. If desired, the chromophore can be graft polymerized onto a polymer which has complementary functional groups (preferably carboxyl groups). Optionally the polymer can then be cross-linked. Such polymers are useable in electro-optical devices.
