  • Publication number: 20200114603
    Abstract: A method of preparing and using a contact lens is disclosed. In one step, a light-absorbing dye solution, comprising a light-absorbing dye disposed in a solution, is dispensed onto a contact lens. In another step, the light-absorbing dye is reacted with the contact lens so that the contact lens permanently contains the light-absorbing dye. The transmission of light of a certain wavelength through the contact lens is reduced due to the reacted light-absorbing dye permanently contained within the contact lens.

  • Patent number: 10528090
    Abstract: Examples disclosed herein provide a hinge assembly for a computing device. One example hinge assembly includes a first bracket attached to a first member of the computing device and a second bracket attached to a second member of the computing device. The hinge assembly includes a hinge pivotally connecting the first bracket to the second bracket along a first axis, and a first gear rotatably connected to the first bracket along the first axis. The hinge assembly further includes a set of gears, each gear from the set of gears rotatably connected to different axes parallel to the first axis. As an example, the set of gears is to provide friction against the first gear to provide a level of resistance to a torque provided when the first bracket is to be moved along the first axis.

  • Patent number: 9789654
    Abstract: A method for manufacturing a silicone hydrogel contact lens is described that comprises curing a polymerizable composition comprising at least one siloxane monomer and at least one hydrophilic vinyl-containing monomer in a contact lens mold comprising a molding surface having a coating comprising a hydrophilic polymer. The hydrophilic coating is not solubilized by the polymerizable composition during the curing step. The resulting polymeric lens body is removed from the mold, washed to remove any of the hydrophilic polymer that may have transferred from the mold surface to the lens during the curing or lens removal process, and packaged to provide a silicone hydrogel contact lens having a contact angle that is lower than what it would otherwise be had the lens been cured in the same contact lens mold lacking the hydrophilic coating.

  • Patent number: 9762417
    Abstract: The present invention pertains to systems and methods for equalizing a digitally modulated input signal for transmission as an optical signal over an optical fiber. In detail, this equalization is accomplished prior to the signal's conversion to an optical signal, and prior to the signal being filtered by a vestigial sideband (VSB) filter. In particular, equalization is accomplished by giving weights to the taps of a tapped delay equalizer, wherein weights for respective taps are derived from the output signal after its conversion to a digital signal at the downstream end of the optical fiber.
