Title: Cyclic implant perfusion, cleaning and passivation process and implant produced thereby
Inventor: GROOMS JAMIE M
IPC: A61F2/06
Filed: 1999-11-08
Abstract: This invention includes a novel method for safely, effectively and efficiently pooling of tissues for treatment prior to implantation into a recipient in need thereof. In one embodiment, the method includes perfusion of a porous implant which achieves efficient interpenetration of desired factors into and removal of undesirable factors from the pores of the implant, cleaning of the implant, efficient passivation of the implant (inactivation of pathogens, microorganisms, cells, viruses and the like and reduction in antigenicity thereof), and the novel implant produced by such treatment. The process presents a system wherein the rate of pressure cycling, the fact of pressure cycling, and the amplitude of pressure cycling, results in highly cleaned tissues and other implants for implantation. Target decontamination goals for this process include between about a one (1) to twelve (12) log reduction in bacterial contamination, between about a one (1) to fifteen (15) log reduction in enveloped virus contamination, up to about a five (5) log reduction in non-enveloped virus contamination, between about a two (2) to ten (10) fold reduction in endotoxin, maintenance of implant or graft biologic and biomechanical properties, absence of tissue toxicity due to cleaning solutions used, and reduced implant antigenicity.

Title: Internally integrated digitally amplified electronic guitar
Inventor: HARRINGTON RICHARD
IPC: G10D1/08
Filed: 2002-02-11
Abstract: The INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR adds new minuature digial technology to standard electric guitars by utilizing various integrated circuits inside the body of the invention to replace the standard external devices standard electric guitars require in order to operate. The external devices the standard electric guitar requires to operate are: (1)-interface cable, (2)-audio amplifier, (3)-speakers) and (4)-speaker cabinet. With standard electric guitars a magnetic coil pickup (or pickups) captures the magnetic flux created by the guitar strings vibrating and carries that signal through a series of tone controls through an I/O connector or out-put jack on the external side of the body of the guitar. An interface cable is then required to be inserted into the guitar at one end and the other end of the interface cable is then inserted into the I/O connector or input jack of an external audio amplifier (powered by AC or DC current) where the signal is boosted and routed to output speakers (which may require or not another separated I/O connection ) between the amplifier and the speaker.   With the INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR all components required for operation are contained within the guitar. The signal passes from the vibration of the strings to a Hex Magnetic or piezo electric MIDI Pickup and is converted from a anlogue signal to digital information. The digital information is then manipulated by internal tone controls via a MIDI (music instrument digital interface) synthesizer and sent to the internal Digital Amplifier which boosts the signal and creates either a mono or stereo output path which connects directly to the systems internal set of Digital Speakers. Due the extreme minuaturization of the IC components the entire system can operate on DC current provided by on-board rechargable batteries. The INTERNALLY INTEGRATED  DIGITALLY AMPLIFIED ELECTRONIC GUITAR offers significant advantages over the standard electric guitar. It is portable and requires non of the external devices that a standard electric guitar does in order to operate.  The INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR can operate anywhere without the need for an external AC power source. The INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR DC power cells can be conveniently recharged with it's on-board charging system and the Digital Amplifier and Digital Speaker system draws less electrical power and delivers superior sound quality over conventional solid state or IC  analogue amplifier/speaker combinations. With the on-board MP3 player/recorder; the musician can record the output of the guitar listen to it later and/or accompany the output of the MP3 player by playing the guitar as the MP3 player replicates what is stored on it's hard drive.

IPC: C12Q1/68
Filed: 2000-02-18
Abstract: L'invention concerne des méthodes et des matières permettant de créer une banque de référence de fragments de restriction à partir d'un mélange d'acides nucléiques contenant un polymorphisme de séquence. De préférence, la méthode de création de la banque consiste: à faire digérer l'ADN génomique provenant d'un mélange d'individus avec une première et une deuxième endonucléase de restriction afin de former une population de fragments de restriction; à isoler les fragments de restriction de la population digérée par la première et par la deuxième endonucléase de restriction puis à former une première population de fragments monocaténaires; à séparer les fragments de restriction de la population digérée par la première endonucléase de restriction mais non par la deuxième endonucléase de restriction puis à former une deuxième population de fragments monocaténaires; à hybrider les première et deuxième populations de fragments monocaténaires pour former une population de duplex; puis à isoler la population de duplex pour créer une banque de référence de fragments de restriction contenant un polymorphisme de séquence. Dans un aspect important, l'invention concerne l'utilisation de la population de référence de fragments de restriction pour comparer les fréquences de séquences polymorphes entre différents mélanges de populations. On peut établir ces comparaisons en effectuant une hybridation compétitive de l'ADN provenant des mélanges respectifs et enrichi par la présence d'un polymorphisme de site de restriction avec l'ADN provenant de la population de référence. De préférence, ces réactions d'hybridation compétitive sont réalisées par la banque de référence reliée à un ou plusieurs supports en phase solide. Idéalement, les éléments de la banque de référence sont liés à des microparticules individuelles de sorte qu'à chaque microparticule est lié un fragment unique. Après l'hybridation compétitive, on peut analyser et trier les microparticules afin d'identifier les microparticules comportant des séquences pour lesquelles les mélanges comparés présentent différentes fréquences polymorphes.

Filed: 2001-05-03
Abstract: A method for enhancing vision of an eye includes a laser delivery system having a laser beam for ablating corneal material from the cornea of the eye.  Measurements are made to determine an optical path difference between a plane wave and a wavefront emanating from the retina of the eye for a location at a surface of the cornea. An optical correction is provided to the laser delivery system for the location based on the optical path difference and refractive indices of media through which the wavefront passes. The optical correction includes dividing the optical path difference by a difference between an index of refraction of corneal material and an index of refraction of air. The laser beam is directed to the location on the surface of the cornea and corneal material ablated at the location in response to the optical correction to cause the wavefront to approximate the shape of the plane wave at that location.

Title: System and method of integrating corneal topographic data and ocular wavefront data with primary ametropia measurements to create a soft contact lens
Inventor: ROSS DENWOOD F
IPC: A61F9/007
Filed: 2000-08-08
Abstract: A system and method is provided for integrating corneal topographic data and ocular wavefront data with primary ametropia measurements to create a soft contact lens design. Corneal topographic data is used to design a better fitting soft contact lens by achieving a contact lens back surface which is uniquely matched to a particular corneal topography, or which is an averaged shape based on the particular corneal topography. In the case of a uniquely matched contact lens back surface, the unique back surface design also corrects for the primary and higher order optical aberrations of the cornea. Additionally, ocular wavefront analysis is used to determine the total optical aberration present in the eye. The total optical aberration, less any corneal optical aberration corrected utilizing the contact lens back surface, is corrected via the contact lens front surface design. The contact lens front surface is further designed to take into account the conventional refractive prescription elements required for a particular eye. As a result, the lens produced exhibits an improved custom fit, optimal refractive error correction and vision.
