  • Patent number: 10880795
    Abstract: The present invention provides a method for handover between access points, and terminal equipment. The method includes: when performing information transmission with a first access point AP on a first frequency band, determining whether the terminal equipment needs to establish a connection with a second AP which is a second frequency band; determining, by the terminal equipment, whether the first AP and the second AP are corresponding to a same dual-band radio access device; sending, by the terminal equipment, a connection request to the second AP when maintaining a protocol layer connection with the first AP; and establishing, by the terminal equipment, the connection with the second AP when the second AP send feedback. In the method, duration required by a process of handover between access points can be reduced, and a user is made not perceive the handover process, thereby improving user experience.

  • Publication number: 20200376788
    Abstract: The invention relates to a pad printing instrument comprising an ink supply system capable of control the temperature, viscosity and colorant concentration of an ink in an ink cup. Such controls are achieved by continuously adding and mixing a cold ink having a composition identical to the ink in the ink cup but having a lower temperature. The continuous addition of a small amount of a cold ink into the ink cup could compensate heat generated by the friction between the ink cup and a cliché and could minimize the evaporation of a diluent in the ink and change in the concentration of colorants in the ink and ink viscosity. The invention also relates to use of a pad printing instrument comprising an ink supply system of the invention for producing colored hydrogel or silicone hydrogel contact lenses.

  • Publication number: 20200376787
    Abstract: The invention provides a thermal cast-molding method for producing colored silicone hydrogel contact lenses. The method of the invention comprises: (1) forming, on a molding surface of a mold, a transferable colored polymeric composite film which comprises or consists essentially of a first polymeric film, a second polymeric film and a cured colored image encapsulated therewithin; (2) dispensing a silicone hydrogel lens formulation into the lens-forming cavity of the mold; and (4) thermally curing the third polymerizable composition within the lens-forming cavity for at least about 40 minutes to form the colored silicone hydrogel contact lens, whereby the transferable, colored, and polymeric composite film detaches from the first or second molding surface and becomes integral with the body of the silicone hydrogel contact lens.

  • Publication number: 20200362082
    Abstract: The invention provides a method for producing photochromic silicone hydrogel (SiHy) contact lenses based on thermal cast-molding technology in a relatively efficient and consistent manner. The method is characterized by selecting a high radical-reactive hydrophilic acrylic monomer while eliminating any low radical-reactive hydrophilic N-vinyl amide monomer in a lens formulation (polymerizable composition), by selecting a weight ratio of low-radical-reactive hydrophilic N-vinyl amide monomer to a high radical-reactive hydrophilic acrylic monomer in a lens formulation if the low radical-reactive hydrophilic N-vinyl amide monomer is needed, and/or by using a relatively high temperature thermal initiator in a lens formulation, to control the lens properties (e.g., water content, elastic modulus, etc.) and lens processability (capability of dry-delensing from molds) of thermally cast-molded SiHy contact lenses while minimizing loss in photochromic ability of resultant SiHy contact lenses.
