  • Publication number: 20180096560
    Abstract: For a game of chance, a selected game value is generated. The selected game value is used to determine whether the player is a winner or a loser. An historical value for a financial asset used to generate the selected game value is displayed. The historical value is generated after the input, receives the game input from, the player and before the display displays the selected game value. The historical value is generated by a financial exchange independent of the gaming table. The historical value generated by the financial exchange is verifiable by an internet query to an information server. An amount of detail displayed for the historical value is based on the selection received from the player.

  • Patent number: 6231583
    Abstract: This invention is a surgical device for producing a circular, interlamellar channel within the corneal stroma. An intracorneal ring can be implanted into this channel at the corneal periphery modifying the corneal curvature while sparing the important central optical zone of the cornea. This channel is formed by the sequential use of two separate instruments. The first instrument, the channel-guide dissector, is a circular dissecting instrument which is a split ring dissector with the dissecting end having a blunt tip and the other end connected to a handle. The important aspect of this channel-guide dissector is that it has a relatively narrow width which results in production of a lamellar corneal channel that is typically too narrow for the insertion of a typical intracorneal ring for myopic adjustment.

  • Patent number: 6228114
    Abstract: An apparatus for adjusting the corneal curvature of the eye comprising a corneal implant having an elongated, hollow tubular shell which is implantable into the cornea in encircling relation to the central optic zone of the cornea. The implant has hinged portions along its the inner and outer arcs, and the corneal implant is filled with a predetermined amount of a biocompatible material in various forms such as rings or strands. The biocompatible material is strategically located within the flexible shell to alter its dimensions in thickness or diameter and thereby adjust the corneal curvature to correct refractive error.

  • Patent number: 6206919
    Abstract: A method and apparatus for adjusting corneal curvature of the eye comprising an adjustable corneal arcuate segment or segments which is implantable into the cornea. The arcuate segment is a flexible hollow shell composed of a synthetic or a natural material, with an annular chamber that is filled with a predetermined amount of a biocompatible material. The corneal curvature is adjusted by removing or augmenting the predetermined amount of biocompatible material contained in the arcuate segment.

  • Patent number: 6159241
    Abstract: Methods are disclosed for adjusting corneal curvature to correct the refractive error of an eye. The method comprises a first corrective event in which the corneal curvature is adjusted to correct the eye to 20/20 vision or slightly over-correct the eye past 20/20 vision. After the first corrective event, a second corrective event adjusts the corneal curvature to 20/20 vision. The second corrective event causes significantly less trauma to the eye, and thus, compared to the first corrective event, the error from healing and other factors is greatly reduced in this second corrective event. Devices for implementing these methods are also disclosed.

  • Patent number: 6066170
    Abstract: A method and apparatus for adjusting corneal curvature of the eye comprising an adjustable split ring formed of an elastic hollow shell which is implantable into the cornea in encircling relation to the central optic zone of the cornea. The ring is filled by a predetermined amount with a select quantity of biocompatible material, either a fluid or strands of biocompatible suture material or polymethylmathacrylate, of predetermined size and length.The biocompatible filler material is strategically located within the elastic shell to alter its dimensions in thickness or diameter and thereby adjust the corneal curvature to correct for refractive error. Further adjustment of the ring may be made post-operatively after implantation by select removal of the biocompatible filler material.

  • Patent number: 5876439
    Abstract: An adjustable intrastromal device adapted for implantation in the cornea and formed of a flexible hollow shell composed of a material such as a silicone or urethane polymer, with a chamber that may be filled with a biocompatible material such as saline or gel. Preferably, the device has more than one compartment, each of which is water-tight and distinct from the other compartments. Each compartment contains a predetermined amount of the biocompatible fluid described, and the device is implanted in the cornea in surrounding relation to the optical zone of the cornea. Increased volume displaced by the ring results in greater flattening of the central anterior corneal curvature thus correcting myopia. Preferably, the myopia is slightly overcorrected resulting in more flattening of the cornea than necessary for optimal vision.

  • Patent number: 4602421
    Abstract: Low noise polycrystalline silicon resistors are fabricated in the following sequence:(1) deposit an appropriate thickness of polysilicon (e.g. 400 nm) on top of an oxidized wafer(2) resistor doping by ion implantation (e.g. phosphorous)(3) heavy doping of the end-contact regions of the polysilicon resistor by high-dose ion implantation(4) patterning the polysilicon resistor(5) oxidation/annealing the polysilicon resistor(6) open contacts to the polysilicon resistor(7) aluminum metallization to form ohmic contacts(8) a long (e.g. 3 hours) low temperature (e.g. at 375.degree.) pure hydrogen annealing to passivate the interface states in the polysilicon resistor. Polyresistors processed this way have a noise figure that is about a factor of three lower than samples processed otherwise. The low temperature post metallization annealing in pure hydrogen passivates the interfaces of polyresistors, reducing the l/f noise normally generated therein.
