  • Patent number: 7167758
    Abstract: Apparatus and methods for treating tissue at or near a sphincter provide for transluminal introduction of an energy delivery device. The device includes a tissue compression member to compress target tissue at or near the sphincter. A radiofrequency energy source is coupleable to the delivery device to deliver radiofrequency energy to the target tissue. Energy is delivered to heat the tissue to a desired temperature. The desired temperature is selected to induce an injury-healing response or to inducing shrinkage of collagen fibers in the target tissue to thereby reduce laxity in the target tissue.

  • Patent number: 7166405
    Abstract: The invention provides liquid toner compositions in which the polymeric binder is chemically grown in the form of copolymeric binder particles dispersed in a liquid carrier. The polymeric binder includes one amphipathic copolymer comprising one or more S material portions and one or more D material portions, wherein the D material portion has a Tg greater than about 55° C. The toners as described herein surprisingly provide compositions that are particularly suitable for electrophotographic processes wherein the transfer of the image from the surface of a photoconductor to an intermediate transfer material or directly to a print medium is carried out without film formation on the photoconductor.

  • Publication number: 20060260988
    Abstract: The invention includes methods, systems and devices for authenticating transactions. A method may begin by enrolling at least two biometric specimens to a database. A false acceptance ratio (“FAR”) is determined for each of the specimens, and authorization options are identified. A cost value is calculated for at least one of the options to provide a calculated cost value (“CCV”). The CCV may be a function of the FAR(s) of the specimen(s) corresponding to the option. An acceptable cost value range (“ACV range”) may be identified, and compared to the CCV. If it is determined that the CCV is in the ACV range, then the option is selected. If the CCV is in the ACV range, then a set of biometric samples is provided (the “sample set”). The sample set is compared to the biometric specimens, and it is determined whether the biometric samples match the biometric specimens. If the biometric samples match the biometric specimens, then the transaction is authorized.

  • Publication number: 20060255424
    Abstract: As robust hinge post structure for use with torsional hinged devices such as micromirrors and method of manufacturing is disclosed. The fabrication process uses a protective layer such as BARC on the bottom of the aperture used to form the hinge post structure to protect an oxide layer during an etching step. The oxide layer, in turn protects the metal layer at the bottom of the aperture. Therefore, the metal layer, the oxide layer, and the protective layer prevent the erosion and/or pitting of the bottom electrode during a cleaning process, and provide additional support to the structure.

  • Patent number: 7112201
    Abstract: An electrosurgical medical device and method for creating thermal welds in engaged tissue. In one embodiment, at least one jaw of the instrument defines a tissue engagement plane carrying a conductive-resistive matrix of a conductively-doped non-conductive elastomer. The engagement surface portions thus can be described as a positive temperature coefficient material that has a unique selected decreased electrical conductance at each selected increased temperature thereof over a targeted treatment range. The conductive-resistive matrix can be engineered to bracket a targeted thermal treatment range, for example about 60° C. to 80° C., at which tissue welding can be accomplished. In one mode of operation, the engagement plane will automatically modulate and spatially localize ohmic heating within the engaged tissue from Rf energy application—across micron-scale portions of the engagement surface.

  • Publication number: 20060204049
    Abstract: The present invention includes a method of deciding whether a data set is acceptable for making a decision. A first probability partition array and a second probability partition array may be provided. A no-match zone may be established and used to calculate a false-acceptance-rate (“FAR”) and/or a false-rejection-rate (“FRR”) for the data set. The FAR and/or the FAR may be compared to desired rates. Based on the comparison, the data set may be either accepted or rejected. The invention may also be embodied as a computer readable memory device for executing the methods.
