Title: Portable and dynamic distributed applications architecture
Inventor: WHITE JOHN W
IPC: G06F9/44
Filed: 1990-09-12
Abstract: ABSTRACT OF THE DISCLOSURE     A  system   and  method   is  disclosed  for  enabling  a plurality  of computers  and associated  computer resources, some or all of which may  be of heterogeneous configuration, to cooperatively process a variety of applications such that the execution is transparent to the user regardless of where the  application  is  actually  executing.  This distributed applications  architecture  performs  an information distri-bution   service  between  multiple  transaction  processing systems by working with a transaction processor via communi-cation  channels  to  other  hosts  within the network and a dialog  manager  (26)  which  uses  a  transaction processor interface   (78)   to   communicate   with  the  transaction processor.   Additionally,  the  architecture  employs a map service  (36,40) to  provide an  editor to allow application programmers  to  create  the  maps  (40) for the application panels,  a compiler to generate the maps into linkable form, and  a  linkable  interpreter  which translates the linkable form into the screen presentation  format for that platform. Furthermore,  to distribute an  application, the source code for the procedures  (32), views (38) and panels are moved as a block to  the new system.   This is possible  because once the application source code is complete, all of the applica-tion logic, user interface control tables, view definitions, and  other application-specific  tables for  one transaction definition are packaged by the present invention in a single load module on the system where the application will reside. The load  module is then compiled  using the target system's compiler,   link  editor,  and   bind  process.   Thus,  all environment-dependent variations of import/export, including network protocol, operating  systems, processor types, etc., are automatically  integrated with  the application  at load module  bind time.   Therefore, no  source code  changes are necessary.

Filed: 1991-03-26
Abstract: POLYPECTOME SNARE WITH BIPOLAR EIECTRODES                     ABSTRACT OF THE DISCLOSURE    A polypectome snare whose loop comprises a pair of electrodes mechanically joined but electrically insulated from one another at their distal ends and adapted to be energized by a source of RF voltage for excising polyps on the inside of a body cavity is described.  The polypectome snare is designed to be used with an endoscope and includes three concentric flexible plastic tubes each having proximal and distal ends and a lumen running the length thereof.  At the proximal end is a hand grip which is secured to the wires leading to the bipolar electrodes.  Two of the concentric flexible tubes are placed within an outermost third concentric flexible tube and extend the length thereof.  Each of the wires passes through the lumen of one of the inner tubes, respectively.          Alternatively, an extruded plastic, double-lumen tube may be used.          The electrode wires pass individually through an associated one of the two lumens and the double lumen tube is itself concentrically disposed in the lumen of an outer sheath or tube.  In this fashion, the wires remain insulated from one another over the length of the instrument  and due  to this  same arrangement,  the conductors comprising the bipolar electrodes cannot become twisted at the distal end of the implement to thereby create a short which would render the snare inoperative.
