  • Patent number: 8053488
    Abstract: An ambient temperature curable hydrophilic PU oligomer includes a PU pre-polymer having a hydrophilic center group and a curable terminated group. The ambient temperature curable hydrophilic PU oligomer includes the moisture-curable hydrophilic PU oligomer such as isocyanate-terminated PU pre-polymer and free-radical curable hydrophlic PU oligomer. The isocyanate-terminated PU pre-polymer is synthesized by mixing at least one multi-isocyanate, at least one polyol and one or more diol monomer with hydrophilic group. The acrylate-terminated PU oligomer is synthesized by adding 2-hydroxyethyl methacrylate (HEMA) into the isocyanate-terminated hydrophilic PU pre-polymer. Either acrylate- or isocyanate-terminated PU oligomer can be applied on a textile or a glass surface with a thin-layer coating technology. The curing reactions of these hydrophilic thin-layer coatings are carried out with moisture or UV-radiation, respectively, at ambient temperature.

  • Publication number: 20100326845
    Abstract: A new electrochemical method for determining dissolved oxygen concentration is developed. It employs cobalt based oxide or complex to modify a conductive electrode surface. This method can be applied to determine dissolved oxygen in regard to medical and environmental demands. The chemical formula of the cobalt based oxide or complexes can be shown as CoxOy or CoaLb. Both “x” and “a” represent the number of cobalt atom; while “y” and “b” represent the number of oxygen atom and the number of coordinating ligand, respectively. For instance, the best known example of cobalt oxide is Co3O4, and the best known examples of cobalt complexes are cobalt phthalocyanine (CoPC) and cyanocobalamin (vitamin B12), or other macrocyclic complexes with a metallic nucleus of cobalt. The present invention determines the concentration of dissolved oxygen in solution in potentiostatic mode with three electrodes. As a result, the dissolved oxygen can be determined between 0.0V and ?0.3V vs.

    Abstract: Disclosed is a thermo-buckled micro actuation unit made of parylene, which is a polymer having high thermal expansion coefficient, for delivering liquid from a source liquid section to a target liquid section, including a substrate on which a thermo-buckled micro actuation unit is formed. The thermo-buckled micro actuation unit includes upper and lower films made of polymers of high thermal expansion coefficient, a metal resistor arranged between the two films, and a flow channel defined between the lower film and the substrate. When electrical power is supplied to the metal resistor, the metal resistor generates heat and the heat is conducted to the upper and lower films, of which the thicknesses are different, whereby a temperature difference is induced therebetween and causing deformation of thermo-buckling, as a result of which the liquid is pumped from the source liquid section, through the flow channel, toward the target liquid section.

  • Patent number: 7288906
    Abstract: A manually operated brushless DC motor is disclosed herein, which is an educational electric motor and can overcome the shortcoming hard to visualize the movement of a motor due to the high-speed rotation of the motor. The manually operated brushless DC motor according to the present invention provides two switches to replace the brushes used in a conventional motor. Users/learners have to alternatively press the switches to complete a closed circuit and drive the motor to rotate. Only when the rotor rotates in synchronism with the pressing rate of the switches, the rotor accelerates. Otherwise the rotation speed of the rotor decreases. The manually operated brushless DC motor provides the users/learners with the opportunity of viewing the rotor rotating in a slow motion, and the experience of manually operating the motor.
