Title: Method and apparatus for unique address assignment, node self-identification and topology mapping for a directed acyclic graph
Inventor: OPRESCU FLORIAN
IPC: G06F13/14
Filed: 1993-12-16
Abstract: A node identification system is described for use in a computer system in which the various components of the system are interconnected via nodes on a communications bus. Once the topology of the nodes has been resolved into an acyclic directed graph, each node may be assigned a non-predetermined unique address. Each node having a plurality of ports has an a priori assigned priority for port selection. Each child node connected to a parent is allowed to respond in the predetermined sequence depending upon the port through which it is connected to its parent. Each node in the graph will announce its presence according to its location in the graph. Each receives an address incremented from the previous addresses assigned, thereby insuring uniqueness. The same mechanism may be implemented to allow each node in turn to broadcast information on the bus concerning the parameters of its local host. Likewise, additional information may be conveyed from each node concerning connections to other nodes thereby allowing a host system to generate a map of the resolved topology including any information about disabled links which may be used for redundancy purposes.

Abstract: There is provided a balloon cuffed tracheostomy tube (150) with a balloon designed so as to enhance the tube's anchorability without sealing the tracheal stoma and to allow for an easier insertion into the trachea than a comparable tube with a thicker balloon. The tracheostomy tube device includes a conventional hollow tube (155) having a proximal end portion (160), a distal end portion (165), and a bend region (170) intermediate of the end portions. The distal end portion of the tube is arranged for insertion' through a patient's throat and tracheal stoma (210) and into the tracheal lumen (200). The device further includes an inflatable balloon (175) enveloping a portion of the tube and positioned substanstially off-center about the bend region of said tube.  The balloon is equal to or less than 30 microns in thickness, allowing for a greater ease of insertion and insertion through a smaller stoma opening, than a comparable tube with a balloon having a thickness greater than 30 microns.

Abstract: A method and apparatus provide for continuous automatic cutting of a web of material wherein the web has a web anomaly that prevents the web from laying flat and straight. The web anomalies include when a web has a non-zero Gaussian curvature and/or where the web or roll of material follows an arc when the roll is unrolled onto a flat surface. These web anomalies may be justified through use of computer controlled cutters that correct the motion trajectory of the cutter relative to the web and also by means of distortions to the support surface upon which the cutting of the web is to occur.

Abstract: A splitter divides an air/product mixture flow, delivered thereto in an air-powered distribution line, between a primary and a secondary distribution channel, which may be flow--coupled to a product hopper or a hose flow-coupled to another product hopper or another splitter.  The air/product mixture enters the inlet of the splitter along an angled downward flow path and exits a primary outlet, flow-coupled to the primary distribution channel, along a vertical downward flow path. Air/product flow is exhausted by a secondary outlet, which is flow--coupled to the secondary distribution channel, at an angled upward flow path. The velocity flow vector along which the air/product mixture is exhausted from the secondary outlet is at an acute angle relative to the velocity flow vector along which the air/product mixture is received by the inlet of the splitter.
