Title: Method and system for providing interoperability among processes written to execute on different operating systems
Inventor: KOUGIOURIS PANAGIOTIS
IPC: G06F9/46
Filed: 1996-04-09
Abstract: An embodiment of the present invention provides an efficient and robust way to facilitate interoperability between two or more processes which were initially written to execute on top of two different operating systems but instead execute on top of a third operating system. Typically, the preferred embodiment begins by launching a parent process which was initially written to execute on top of a first operating system. The preferred embodiment then obtains a context object that implements a naming graph for the parent process. The context object includes bindings between a given set of names and an associated set of objects that are specific to the first operating system. At some point during execution of the parent process, the parent process spawns a child process which was initially written to execute on top of a second operating system. Next, the parent process instantiates a copy of its context object. The parent process then performs a context merge operation which ensures that object names used by the second process are interpreted relative to a context object associated with the second operating system before (or in lieu of) being interpreted relative to the context object for the first operating system. Once the context merge operation is complete, the new context object is passed to the child process and execution of the second process begins. System calls initiated by the child process will therefore be interpreted relative to the name space for the second operating system. In this way two processes which were initially written to execute on top of two different operating systems can interoperate while executing on top of yet a third operating system.

Title: Method for drying and sintering an optical fiber preform
Inventor: GEROW THOMAS DEWITT
IPC: C03B37/014
Filed: 1996-04-23
Abstract: The invention relates to a method of drying and sintering porous optical fiber preforms, especially those consisting of a solid glass core cane surrounded by a layer of cladding soot.  The porous preform is heated isothermally and dried in a chlorine atmosphere.  The porous preform is again isothermally heated to increase its temperature to just below that at which it would begin to rapidly densify.   The temperature of the  tip  of  the preform is then increased to sintering  temperature.  After the preform tip densifies and clarifies, the  hot zone traverses the preform so that sintering  progresses from the initially consolidated tip to the other end  of  the preform.  By isothermally increasing the furnace temperature to just below sintering temperatures, the entire preform is preheated and, ultimately,  the time subsequently required at sintering temperatures is markedly reduced.

Title: Purine compositions and methods for administration
Inventor: FUKUNAGA ATSUO F
IPC: C07H19/167
Filed: 1994-11-21
Abstract: A purine compound, which has a desired and an undesired effect when a dosage sufficient to induce the desired effect is administered to a mammal, is combined with a counteracting agent, wherein the counteracting agent can reduce the undesired effect when the combination containing an effective amount of the purine compound is administered to a mammal. In a preferred embodiment, an adenosine compound is combined in vitro with catecholamine in a predetermined ratio to form an adenosine composition. Very high dosages of a purine compound, such as adenosine, ATP or their analogs can be administered to a mammal via administration of compositions containing the purine compound and a counteracting agent, while reducing the dangerous, undesired effects associated with administering the same dosage of purine compound without first combining it with the counteracting agent. New catecholamine are also taught. The purine and catecholamine compositions of the present invention pioneer new therapies which take advantage of the diversity of physiological effects of purine and catecholamine compounds.

Title: Circuit and method of testing for silent faults in a bi-directional optical communication system
Inventor: TREMBLAY YVES
IPC: H04B10/12
Filed: 1996-07-31
Abstract: In optical communications systems crosstalk can result in what is termed silent failure. In silent failure, a faulty transmitter appears to function correctly because a receiver in communication therewith is receiving a signal induced by crosstalk. The invention overcomes this problem by tapping the received signal and monitoring it external to the receiver in order to ensure adequate signal levels for a received signal. A microcontroller disables the failed circuit and in an embodiment switches the communication functions to a stand-by circuit.
