Abstract: A system and method for detecting perforations in a body cavity. In accordance with the method of the invention, a fluid (liquid or gas) is delivered into a body cavity to slightly pressurize the cavity. A pressure sensing system monitors the pressure within the cavity for a predetermined test period. If cavity pressure is not substantially sustained during the test period, the physician is alerted to further assess the cavity for perforations before initiating treatment within the cavity. In a preferred form of the system, a medical treatment system such as an RF ablation system is provided with perforation detection functionality. The system preferably includes a pre-test and post-test lockout system.

Abstract: There was perceived a lack of information regarding higher strength materials for sinter-forging automotive applications. Work, therefore, was undertaken to develop new higher strength materials for sinter-forging automotive applications and to fill this lack of information. Accordingly, a connecting rod that comprises an iron-based powder metal mixture was developed. The mixture comprises between 3.01% and 3.03% by weight of copper, between 0.57% and 0.64% by weight of carbon, between 0.32% and 0.33% by weight of manganese, and about 0.13% by weight of sulfur.

Abstract: Various embodiments of the present invention relate to a system for distributing data (e.g., content data) over a computer network and a method of arranging receiver nodes in a computer network such that the capacity of a server is effectively increased (e.g., the capacity of a server may be effectively multiplied many times over; the capacity of the server may be effectively increased exponentially). In one embodiment the present invention may take advantage of the excess capacity many receiver nodes possess, and may use such receiver nodes as repeaters. The distribution system may include node(s) having database(s) which indicate ancestor(s) and/or descendant(s) of the node so that reconfiguration of the distribution network may be accomplished without burdening the system's primary server.

Abstract: The guard tour system of the present invention is comprised of a central computer which runs a computer program that enables a variety of electronic hardware components to function as the guard tour system. As a guard progresses through a guard tour, he or she uses a touch button reader to read information stored within a plurality of touch memory buttons located along the patrol route. At the end of the patrol, the guard places the touch button reader in a downloader that transfers the stored data to the central computer which processes the data and generates reports summarizing the patrol data. The computer program of the present invention provides a novel method of organizing security information in hierarchical categories. Further, the guard tour system of the present invention uses a novel method to determine the number of times a guard visited a location in a given time period.

Abstract: A machine-readable definition of a scene including three dimensional objects is represented. A schematic representation of the scene displays an object in which elements of the object are defined by nodes and relationships between these nodes are represented by links. Several unique relationship types are used to define specific functions applying to a node or between nodes. Selection data is received in response to user input that selects one of the relationship types. Appearance of the displayed links is modified so as to identify occurrences of the selected type to the user. Furthermore, a link may be added to display a relationship type defining a specific function for two or more nodes.

Abstract: A video-on-demand system transfers a control screen signal to a second communication system and receives a viewer control signal from the second communication system. The video-on-demand system transfers video signals to either a first communication system or the second communication system based on the viewer control signal. The second communication system uses less bandwidth to transfer the video signals than the first communications system. The control screen could be a web page that includes: 1) a video display menu with a selection of displays and bandwidths to display the video signals, 2) a video content menu with a video preview selection, and/or 3) a video display control menu comprising play, pause, rewind, fast forward, and stop. The video-on-demand system implements the control screen menu selections.
