摘要:
Tobacco products improved by the use of uncured, green tobacco and propolis for use in smoking tobacco, chewing tobacco, tobacco chewing gum, beverages and foods. In one preferred embodiment green tobacco provides reduced carcinogenic nitrosamines. In another preferred embodiment, the addition of propolis reduces bitterness, prolongs flavor and shelf life, and reduces tar and particulate content. The tobacco products can be used to reduce smoking withdrawal symptoms such as irritability and weight gain by providing nicotine and monoamine oxidase B inhibitor. Further, the invention can be used to treat Alzheimer's disease and to manage weight control in non-smokers.
摘要:
Tobacco products improved by the use of uncured, yellow tobacco low in tar and carcinogenic nitrosamines, treated by microwaving, or convection heating, or freeze drying to kill microbes responsible for curing, for use in smoking tobacco, chewing tobacco, tobacco chewing gum, beverages and foods. In one preferred embodiment tobacco, uncured or cured, is microwaved to reduce further tar and carcinogenic nitrosamines.

A device and method is disclosed for the contemporaneous creation of a digital copy of a written document using a self-contained, hand-held communications device. The self-contained device functions as a writing device and as a digital documenter. It allows for maintenance of position sense within a document thus enabling the user to write cursive, print, draw, write mathematical formulas, draw symbols, punctuate, edit and the like. The invention discloses a self-contained apparatus and method for determining position sense without reliance on special paper, pads, or attachments to the document. The system provides position sense during writing by quantitative comparative analysis of serial images of the surface imperfections of the document. Character generation is discriminated from noncharacter-generating positional changes such as spacing between words. Encryption of data output from the device provides privacy. Encryption and attachment of the device's unique identifying code to a digital copy of a document created by the device provides for confirmation of the source. Uses of the device include short text messaging for cell phones, email composition, note taking in business and education, medical records, and electronic commerce. The imaging system can also be used to read barcodes on documents, allowing for applications to inventory control. Transmission of the digital copy of the document can be through a wired or wireless connection to external digital devices such as cellular phone, personal digital assistant, netpliance, or computer.

A microkeratome for improved corneal flap production for corneal surgery. The microkeratome, having a first aperture and a cutting blade, includes a second aperture located just below the plane of the cutting blade and through which a corneal plug protrudes in preparation for the lamellar cut of the microkeratome to create a uniformly thick lamellar flap of predetermined diameter and depth. The second aperture can include a second cutting blade. The microkeratome also includes a transparent applanation plate positioned at a predetermined distance above the plane of the cutting blade and an adjustable stop to prevent complete transection of the corneal flap.

A writing instrument that also functions as a computer peripheral. The writing instrument has the general configuration of a ball-point pen. The pen includes a ball for ink writing that is operatively associated with internal sensors that precisely detect the distance and direction of ball movement and relay that directional and distance data to a microprocessor which records a series of vectors similar to a computer mouse. The pen also includes interchangeable memory cartridge for the storage of the data and a wireless computer connect, for example infrared, that can communicate generated or stored data to an associated computer. The pen also includes an external LED data display, a speaker/microphone and an ink reservoir.
摘要:
A thin, pliable mat to enhance visualization of corneal topography during rastostereography or videokeratoscopy. The mat is approximately 20 microns or less in thickness and constructed from hydrophobic material. In one preferred embodiment, the mat has a pattern etched thereon. In an alternative embodiment, a pattern is projected onto the mat. For rastostereography the pattern is a grid. For videokeratoscopy the pattern is concentric circles. The mat conforms to the surface of the cornea and the pattern is analyzed using conventional technology to determine corneal topography.

A method of using rastophotogrammetry and Placido-disc videokeratoscopy in ophthalmological surgery to calibrate a surgical laser wherein the effect of laser ablation on various substrates is measured by performing rastophotogrammetry or Placido-disc videokeratoscopy on the substrate before and after laser ablation to determine whether there is a uniform ablation and no unwanted effects created by the laser. The substrate can be calibration block, an intraoccular lens implant, a contact lens, an artificial cornea, or cornea.

An improved apparatus and method of intraocular pressure determination is disclosed in which applanation tonometry is done with an ultrasonic transducer. The method allows for increased accuracy of intraocular pressure determination based upon adjustment of applanation tonometry for subjacent corneal thickness. The device allows for the operator to view the corneal surface and the pattern of dye to determine the precise endpoint of applanation.
摘要:
A method for enhancing the accuracy of PRK wherein a UV power meter is placed in the optical path of the laser beam. In one preferred embodiment, the power meter is placed distal to the last optical element so that any optical degradation that affects laser performance is taken into account. The meter consists of a UV-B cube and a pulnix camera with a software package. The meter is used to monitor the fluence of each laser pulse. The power meter is used to size each pulse and to quantify the energy in each pulse. Sensing means is employed to measure intraoperative pulse-to-pulse energy during photorefractive keratectomy (PRK), using said data in conjunction with the location of the pulse within the ablation zone to determine the cumulative energy thus being achieved, and adjusting said laser to treat more or less at each point based upon the difference between the ideal cumulative energy map and the observed cumulative energy map derived from intraoperative power determination.
