Surgical stapling instrument having end effector gripping surfaces

A surgical instrument for being endoscopically or laparoscopically inserted through a cannula of a trocar into an insufflated body cavity or lumen (“surgical site”) for simultaneous stapling and severing of tissue including gripping surfaces on inner surfaces of an upper and lower jaw that enhance use as a grasping instrument to preposition tissue prior to performing a stapling and severing procedure. An illustrative version advantageously includes a separate closure trigger and closure mechanism that facilitates use as a grasper without the possibility for inadvertent firing (i.e., stapling and severing).

Automated annular plication for mitral valve repair

InactiveUS6913608B2Stabilize and improve left ventricular functionAvoid developmentSuture equipmentsBone implantMitral valve leafletMitral valve operation
A novel system for performing a heart valve annuloplasty. The system involves the use of a plication band. In one embodiment, the annulus of the valve is reduced by constriction of the plication band itself. More particularly, each plication band enters the tissue at two or more points which are spaced from one other by a distance which is dictated by the geometry of the plication band. Subsequent constriction of the plication band causes these points to move toward each other, thereby constricting the tissue trapped between these points and thus reducing the overall circumference of the valve annulus. In a second embodiment, the annulus of the valve is reduced by linking multiple plication bands to one other, using a linkage construct, and then using a shortening of the length of the linkage construct between each plication band so as to gather the tissue between each plication band, whereby to reduce the overall circumference of the valve annulus.

Apparatus and method of optimizing power system efficiency using a power loss model

A power subsystem is actively optimized to improve total subsystem efficiency in a way that is responsive to changes in load requirements, power supply variations, and subsystem temperature variations. Detailed, multidimensional power loss models are developed for constituent devices which are then combined into a power subsystem containing a controller and circuity for measuring device operating parameters such as input and output voltage, output current, and temperature. Operating parameters are continually monitored, and set points are correspondingly changed based on the detailed power loss models to achieve maximum overall efficiency for the instantaneous operating state of the system.

Robust system for screening mail for biological agents

Items of mail are rapidly processed in a mail sampling system to determine if the mail is contaminated with a chemical or biological agent. The mail sampling system maintains a negative pressure in a containment chamber and includes a triggering sampler that makes a threshold determination regarding possible contamination, and a detecting sampler that obtains a sample for more detailed analysis in response to a signal from the triggering sampler. A sample of particulates collected from an item of mail is either removed for analysis or analyzed in the system to identify a contaminating agent. Optionally, the system includes an archiving sampler, which archives samples for subsequent processing and analysis, and a decontamination system, which is activated to decontaminate the mail if needed.

Optoelectronic element with a non-protruding lens

An optoelectronic component has a lens that is formed in the surface of an encapsulant surrounding a semiconductor diode element. With respect to emitters, the lens reduces internal reflection and reduces dispersion to increase overall efficiency. With respect to detectors, the lens focuses photons on the active area of the detector, increasing detector sensitivity, which allows a detector having a reduced size and reduced cost for a given application. The lens portion of the encapsulant is generally nonprotruding from the surrounding portions of the encapsulant reducing contact surface pressure caused by the optoelectronic component. This non-protruding lens is particularly useful in pulse oximetry sensor applications. The lens is advantageously formed with a contoured-tip ejector pin incorporated into the encapsulant transfer mold, and the lens shape facilitates mold release.

Predictive modeling of consumer financial behavior using supervised segmentation and nearest-neighbor matching

Predictive modeling of consumer financial behavior, including determination of likely responses to particular marketing efforts, is provided by application of consumer transaction data to predictive models associated with merchant segments. The merchant segments are derived from the consumer transaction data based on co-occurrences of merchants in sequences of transactions. Merchant vectors represent specific merchants, and are aligned in a vector space as a function of the degree to which the merchants co-occur more or less frequently than expected. Consumer vectors are developed within the vector space, to represent interests of particular consumers by virtue of relative vector positions of consumer and merchant vectors. Various techniques, including clustering, supervised segmentation, and nearest-neighbor analysis, are applied separately or in combination to generate improved predictions of consumer behavior.

Luminous lamp having an ultraviolet filtering and explosion proof thin film

A luminous lamp having an ultraviolet filtering and explosion-proof thin film is disclosed. An outside of a lamp is coated by a transparent layer which comprises phosphor powder. Energy generated by the lamp is absorbed by the phosphor powder while the lamp is shining. The phosphor powder would release energy to shot brilliance, so as to provide auxiliary lighting after turning off the lamp. Additionally, the phosphor powder can absorb harmful ultraviolet and other harmful radiations with shorter wavelengths to be one part of the thin film for filtering harmful radiations. The harmful ultraviolet can be transformed by the phosphor powder into visible light to red shift radiations with short wavelengths; hence the harmful radiations with shorter wavelengths can be eliminated. The illumination of visible light can be further increased. The transparent layer can catch broken fragments of the outside of the lamp to decrease accidents when the lamp is broken.

System and method for use of distributed electronic wallets

Methods and systems whereby two electronic wallets communicate and exchange information. In one such system, a consumer's personal electronic wallet communicates with the exclusive or preferred wallet of a web merchant. In one such system, an internet consumer registers with a web merchant's exclusive or preferred electronic wallet (“merchant wallet”) and provides consumer information (e.g., credit card number, mailing address, and other information) to the merchant wallet, which is stored by the merchant wallet in a database on the merchant server. Such information may be automatically populated by the consumer's personal electronic wallet. The consumer maintains current consumer information in a consumer electronic wallet on the consumer's personal computer. When the consumer visits the merchant site again, and orders goods or services, the merchant's preferred wallet can be automatically updated by the consumer's electronic wallet if any of the data in the merchant's wallet has changed. For example, the consumer wallet examines the information in the merchant wallet to determine if the information in the merchant wallet conforms to the current information in the consumer wallet. If the information does not conform, the consumer wallet communicates the current consumer information to the merchant wallet.
