  • Patent number: 11213919
    Abstract: A method of preparing antimicrobial surface on medical devices: first, producing multi-functional surface with bacterial anti-adhesion and self-cleaning functions through single-stop ultrafast laser fabrication approach for development of micro/nano patterns, then producing bactericidal thin film through depositing metal nanoparticles on those micro/nano patterned surfaces. The combination of bacterial anti-adhesion and bactericidal film can inhibit initial bacterial adhesion and release heavy metal ions to kill the bacteria simultaneously. Meanwhile, the multi-functional surface with self-cleaning function can prevent the killed bacteria from accumulating at the substrate surface, thereby obtaining long-lasting antibacterial effect.

  • Patent number: 11208720
    Abstract: The present invention improves the surface modification of NiTi alloys used for instance in medical devices through treatment with hydrogen particles in a suitable gaseous discharge and with oxygen atoms. The technique according to the present invention provides the formation of biocompatible solely titanium oxide layer thus preventing nickel to be present in the top surface layer. Furthermore this enables nanostructuring of the surface which depends on the treatment conditions. Devices made from NiTi alloys treated with the method according to the present invention have improved biocompatibility; platelets do not readily attach and activate on such surfaces and the thrombus formation rate is reduced in comparison with extensively used untreated NiTi alloys.

  • Patent number: 11186747
    Abstract: An asphalt shingle coating system that includes a coater, a mixer, a viscosity gauge, a wax supply, a wax pump and a control system. The coater applies a layer of a coating asphalt mixture on an asphalt shingle substrate. The mixer mixes the coating asphalt mixture and is positioned upstream of the coater. The viscosity gauge may be positioned between the coater and the mixer, and it measures the viscosity of said coating asphalt mixture before it is delivered to the coater. The wax supply is in fluid communication with the mixer and a wax pump may deliver a volume of wax from the wax supply to the mixer, and the control system may selectively adjust the operation of the wax pump to substantially maintain a desired viscosity of said coating asphalt mixture.
