A qualifying connection for an instrument attaches to a source of electrosurgery energy to and the instrument and has first and second parts coupled to the instrument and the source, respectively. Optical couplings on the connection transmit invisible energy to identify the instrument and are proximate on the first and second parts. A light modifier on the first part is proximal to the second part for modification of radiation in the infrared wavelengths so infrared transmitters encode signals and non contact coded proximity detectors on the second part are the coupled detectors. Non contact coded proximity detectors respond to modified infrared light establishing an Nth bit identification code. An infrared light supply in the source pass from the transmitters across the communicating couplings for encoding signals by modification of the infrared light with a light modifier. Mechanical attachments include conjugating male and female portions physically extending between the parts for mating engagement. The attachments juxtaposition the parts when the attachments geometrically conjugate to geographically positioning the couplings proximate for communicating. The attachments have one or more conductors for delivery of high frequency energy from the source to the instrument. A cable fits between the first part of the connection and the instrument and has electrical conductors for carrying energy passing through the first part of the connection from the source to the instrument. An identifying circuit couples to the second part and responds to invisible light optically communicated across the couplings for verifying the type of instrument connected by the cable to the source.

A tissue welding apparatus is adapted to fuse a first piece of tissue to a second piece of tissue which are disposed in a surface proximate relationship. An elongate shaft carries a first jaw, and a second opposing jaw moveable relative to the first jaw. At least one penetrating member is carried by the first jaw and moveable relative to the second jaw to create a channel through the first piece of material and the second piece of material. A source of heat is coupled to the penetrating member for denaturing the tissue defining the channel. This denatured tissue forms a column binding the first piece of tissue to the second piece of tissue. A chemical agent can be carried to the tissue with the penetrating member.

A method and apparatus for obtaining information about an object through interaction between a mobile station (MS) and a computer network such as the Internet, and communicating the information to the MS. A digital camera obtains an image of an object, such as a geographic region proximate the MS, which is then transmitted through the mobile communications system to the computer network. A converter server such as an Optical Character Reader (OCR) server interfaced with the global computer network converts the digital image to a text format which is then compared, along with a general location identifier of the MS to geographic data stored in a location database connected to the global computer network. Based on a comparison of the converted text data and the general location identifier of the MS to the geographic data stored in the location server, a precise location of the MS is determined and transmitted to the MS.
