Title: A method of corneal surgery by laser incising a contoured corneal flap
Inventor: JUHASZ TIBOR
IPC: A61B18/20
Filed: 2001-01-12
Granted: 2011-08-16
Abstract: In accordance with the present invention, a method for corneal laser surgery includes the step of first prescribing the size, shape and location of a lentoid of stromal tissue to be removed in order to correct the vision of a patient. Next, a contoured corneal flap having an interior surface and peripheral edge is created wherein the interior surface of the flap is shaped to conform to the prescribed anterior surface of the lentoid. To create the flap, the focal point of a pulsed laser beam is moved within the intrastromal tissue to photoalter a layer of tissue in the shape of the interior surface and the peripheral edge of the flap. Once created, the flap can be lifted to expose a bed of intrastromal tissue. Then, an excimer laser can be used to photoalter the bed of intrastromal tissue in a predetermined manner, thus creating a void in the shape of the prescribed lentoid. Finally, the flap can be repositioned over the lentoid shaped void and allowed to heal. The result is a reshaped cornea that effectively corrects a patient's vision impairment.

Abstract: The present invention provides a broad band, multi-band radar detector which may be configured so as to have two or three down conversion stages. There are three mixers in the circuit, the second of which has a frequency synthesized local oscillator which is governed by a phase lock loop feedback circuit under the control of a microprocessor, so that the output frequency of the second local oscillator may be varied by an amount equal to ~ fadj. The first local oscillator is also under the control of the microprocessor, so that a specific intermediate frequency signal from the first mixer may be derived. By varying the frequency of the second frequency synthesized local oscillator, the tuning range of the radar detector may be increased in each frequency band of interest by an amount equal to ~ fadj for all frequency values in each respective frequency band of interest. The radar detector is self-calibrating detector, so that the output frequency from the first swept local oscillator may be accurately controlled by determining the specific tuning voltage for a specific first local oscillator frequency at which a particular incoming radar signal may be detected. This is accomplished by bypassing the second mixer, and controlling its output frequency so that a harmonic frequency will mix with the first local oscillator frequency to give a calibration response for any predetermined input radar frequency. Accordingly, the problem of drift of the tuning capability of the radar detector may be accurately controlled.

Granted: 2009-05-26
Abstract: A process for the production of precipitated calcium carbonate. A slurry of calcium hydroxide is agitated in a pressurized reactor, and carbon dioxide is provided under pressure to the reactor to produce precipitated calcium carbonate at a high reaction rate. Carbon dioxide is utilized at a high efficiency. Solubilized calcium ions and carbonate ions react to produce a calcium carbonate precipitate. Control of process conditions such as temperature, slurry concentration, and pressure, enables production of a desired crystal habit (including sclenohedral, rhombohedral, stacked rombohedral, or aragonite crystal structures), crystal size, or crystal aspect ratio. The precipitated calcium carbonate produced by the process under pressure is useful as either a paper filler or as an ingredient in paper coatings, and provides a paper product with improved preselected properties, which properties include opacity, density, and/or brightness.

Abstract: A method and system for reducing the time it takes for a trader to place a trade when electronically trading on an exchange, thus increasing the likelihood that the trader will have orders filled at desirable prices and quantities. The "Mercury" display and trading method of the present invention ensure fast and accurate execution of trades by displaying market depth on a vertical or horizontal plane, which fluctuates logically up or down, left or right across the plane as the market prices fluctuate. This allows the trader to trade quickly and efficiently. The price consolidation feature of the present invention, as described herein, enables a trader to consolidate a number of prices in order to condense the display. Such action allows a trader to view a greater range of prices and a greater number of orders in the market at any given time. By consolidating prices, and therefore orders, a trader reduces the risk of a favorable order scrolling from the screen prior to filling a bid or ask on that order at a favorable price.
