Abstract: L'invention concerne un procédé in vitro destiné à améliorer la complémentarité d'une séquence polynucléotidique hétéroduplex. Ce procédé consiste à hybrider des brins opposés afin de former un polynucléotide duplex avec des mésappariements. Le polynucléotide hétéroduplex est combiné avec une quantité efficace d'enzymes possédant une activité de clivage de brin, une activité exonucléase de 5' en 3', et une activité polymérase, et laissant un temps suffisant pour accroître le pourcentage de complémentarité dans l'hétéroduplex. Tous les polynucléotides hétéroduplex n'auront pas tous leurs mésappariements résolus à la complémentarité. Le polynucleotide qui en résulte est éventuellement ligaturé. Plusieurs polynucleotides différents en résultent. Aux endroits où l'un des brins opposés calibre le recodage dans l'autre brin, la complémentarité de pourcentage résultante de la séquence polynucléotidique hétéroduplex est augmentée. Les polynucleotides parents doivent être clivés en fragments avant l'hybridisation des brins hétérologues. C'est pourquoi le réassemblage n'est pas nécessaire.

Abstract: In one embodiment, the invention provides a method for forming a full color laser engraved image on an ID card. As described below, a special image capable layer (200) is prepared that is addressable by one or more near infrared (NIR) lasers (208, 210, 212). Each type of particle (202, 204, 206) contained within the image capable layer (200) is associated with a particular color (e.g., cyan, magenta, or yellow) and is responsive (i.e., can selectively absorb) a particular wavelength of laser energy to form a laser engraved pixel in that respective color. In one embodiment, the particles (202, 204, 206) are selected such that the wavelengths that they respond to do not overlap significantly. By providing discrete physical particles and preventing a given particle from responding to more than one laser wavelenght, it can be possible to minimize so-called "cross talk" between the cyan, magenta, and yellow centers and minimize contamination and/or chemical mixing of image formers. This helps to ensure image accuracy and quality.

Abstract: A novel method for characterizing nucleic acids. A nucleic acid is combined with a double stranded nucleic acid-specific dye to form a detectable complex between the dye and one or more double stranded structures within the nucleic acid. The combination is then exposed to varying temperatures and the fluorescence emission of the dye is measured to determine the melting temperature(s) for the double stranded structures. In some embodiments that melting temperature profile is then compared to melting temperature profiles generated for other nucleic acid(s) to discern differences between the compared nucleic acids.

Abstract: An orthodontic appliance (110,400), a system (100) and a method are provided for automatic tooth straightening. The appliance (110,400) may be fabricated manually or by stereolithography using a computer program (106) that formulates a three-dimensional digital model (107). The appliance (110,400) or series of appliances (110,400) may be made to fit a particular patient wherein a portion of the appliance (110,400) may be attached to fully erupted teeth (306) that are substantially straight. The appliance (110,400) may fit onto the teeth (306) that do not require straightening using a section (402) made from a relatively stiff material so that the appliance (110,400) remains in the mouth in a relative constant position. The erupted teeth (302) that require straightening may be straightened with an area (404) of the appliance (110,400) formed of a softer, more resilient material so that fewer appliances may be required than if a stiffer material were used. The unerrupted teeth (304) may be guided into the mouth by another portion (406) of the appliance (110,400) that is performed with predicted sizes and shapes of teeth determined from anatomical standards. The appliance (110,400) may be formed of a hard stiffer inner shell (502) overlaid by a soft outer layer (501).

Title: Magnetic indexer for high accuracy hole drilling
Inventor: GEORGESON GARY E
IPC: B23B49/00
Filed: 2003-04-29
Granted: 2009-07-14
Abstract: A magnetic indexer (10) for locating a device (26) producing a magnetic field in a blind or inaccessible position of a work piece (36). A magnet (26) is initially placed on a first side of the work piece (36) such that a magnetic field produced by the magnet extends through the work piece (36) and substantially perpendicular to a surface of the work piece (36). A device comprising a plurality of probes (18,20,22) for sensing magnetic fields is then positioned over a second surface of the work piece (36). The probes (18,20,22) are then moved over the second surface to determine the location of the axis (26a) of the magnet (26) via the strength of the sensed magnetic field. Once the position of the axis (26a) of the magnet (26) is determined, the work surface is either marked or worked on through the platform on which the probes (18,20,22) are positioned. In particular, a hole may be accurately drilled or otherwise formed directly over the magnet (26) even when the first surface of the work piece (26) cannot be seen. Additionally, the present invention allows a very accurate positioning of a work tool on the second surface without the need to first visualize the first surface of the work piece (36).

Title: Outer loop/weighted open loop power control in a time division duplex communication system
Inventor: ZEIRA ARIELA
IPC: H04W52/06
Filed: 2000-03-22
Granted: 2011-01-18
Abstract: Outer loop/weighted open loop power control controls transmission power levels in a spread spectrum time division duplex communication station. At a first communication station, errors are measured in a received communication from a second communication station. Based on in part the measured errors, an adjustment in a target level is determined. The first station transmits a communication and the target adjustment to the second station. The second station measures the first station's communication's received power level. Based on in part the received power level, a path loss is determined. The target level is adjusted in response to receiving the target adjustment. The quality of the path loss is determined with respect to a subsequent communication to be transmitted from the second station. The second station's transmission power level for the subsequent communication is adjusted based on in part the determined path loss, the determined quality and the adjusted target level.

Calibration includes a calibration light source in a factory test apparatus operated at a fixed power level and collecting the full spectrum power distribution of the calibration light source to generate a first data set. The calibration light source is then installed in a client test apparatus and operated at the fixed power level in order to collect the full spectrum power distribution and generate a second data set. The first and second data sets are filtered and aligned to determine a system response factor of the client test apparatus so that the irradiance level control may be calibrated.

Abstract: Broadcast segment recognition systems and methods are provided in which a signature representing a monitored broadcast segment is compared with broadcast segment signatures in a data base representing known broadcast segments to determine whether a match exists. Criteria for determining the validity of such a match are provided. In one aspect, signatures representing audio broadcast signals are formed by comparing temporally displaced portions of respective frequency band values within plural frequency bands of the broadcast audio signal. Systems and methods are provided for producing signatures representing intervals of a video signal which compensate for shifts in an edge of a picture represented by the video signal. In addition, signatures characterizing respective intervals of a broadcast signal exhibiting correlation are produced by generating a difference vector for each respective interval and carrying out vector transformations of the different vectors to reduce such correlation. Moreover, signatures characterizing intervals of a video signal are produced with corresponding mask words representing reliability of values comprising the signature. Mask words of first and second signatures thus formed representing different portions of the video signal displaced from one another are compared to establish the values of the mask word.
