Abstract: A fiber intensity reducer comprises a guided system fiber including a core and an outer cladding layer, an unguided fiber intensity reducing (FIR) section including a first fiber “end cap fiber” having a first end and a second end attached at its first end to the system fiber. A bond region is between the first end of the first fiber and the system fiber. The FIR section provides a softening point of at least 700° C. throughout and provides a sufficient transverse dimension along its entire length so that a beam of radiation received from the system fiber expanding therein avoids an interface with the air along its entire length. In one arrangement, the FIR section includes an outer capillary on the end cap fiber, wherein the capillary and the end cap fiber provide refractive index matching.

Abstract: The present invention can include an automated method controlling the fan speed of computer system cooling fans with altitude and/or fluid density data from a centralized sensor. Such a method can utilize a centralized sensor to determine the altitude/fluid density within an enclosed area. The centralized sensor can be positioned so as to be unaffected by extraneous activities within the enclosed area. The determined altitude/fluid density can be conveyed to a computer system containing one or more cooling fans. The computer system can be located within the enclosed area. Then, the computer system can determine the need for adjusting the speed of the cooling fans based on the altitude/fluid density. When the need for adjustment exists, the speed of the cooling fans can be adjusted in accordance with the altitude/fluid density.

Abstract: The present invention can include an automated solution for resolving conflicts between multiple automation managers in the management of a software resource. In this solution, an automation manager can detect a change in the operating state of a software resource within a computing system. A state change indication can be automatically analyzed. The state change indication can be automatically set by the software resource in response to the change in the operating state. Based upon the analysis of the state change indication, the automation manager can determine if the change in the operating state is deliberate. When the change is determined to be deliberate, the automation manager can accept the change in the operating state as the desired state of the software resource.

Abstract: A method for deleting expired items in a queue data structure, the queue data structure comprising a sequential list of ordered data items including a queue head at one end of the sequential list and a queue tail at another end of the sequential list, wherein each data item includes an expiry time, the method comprising: generating a maximum interval value corresponding to a maximum time interval between an expiry time of a first item in the queue and an expiry time of a second item in the queue, wherein the second item is nearer the queue head than the first item; sequentially scanning the list of ordered items from the queue head; responsive to a determination that a scanned item is expired, deleting the scanned item; responsive to a determination that a scanned item will not expire for a time interval greater than the maximum interval value, terminating scanning of the list of ordered items.

Abstract: A method and apparatus to guarantee type safety in multithreaded programs, and to guarantee initialization safety in well-behaved multithreaded programs. A plurality of bytecodes representing a program are received and examined to identify bytecodes defining object creation operations and object initialization operations. Upon execution of the plurality of bytecodes, memory barrier operations are performed subsequent to the performance of both the object creation operations and the object initialization operations. This guarantees type safety, and further guarantees initialization safety if the program is well-behaved. Optimization algorithms may also be applied in the compilation of bytecodes to improve performance.

Abstract: A dynamic inventory management method can include the step of attaching a location tag to a deployable asset. A mobile entity can be associated with the location tag. A tag scanner can scan for location tags within a range of the tag scanner. Data can be conveyed from the tag scanner to a communicatively linked inventory control system. The scanning and conveying steps can be repeated to dynamically update the inventory control system.

Abstract: A wizard that from a fixed design can create various audio interfaces. The generated interfaces can be speech only, DTMF only, or various mixed speech and DTMF UIs. When specifying both speech and DTMF prompts, a number of combinations of these interfaces could be automatically generated. Robust speech recognition systems can be built by automatically generating a “shadow” DTMF application. The DTMF application will perform the same task as the primary speech application; however the transfer to a DTMF application could be done explicitly by the user, or could be transferred automatically (either a temporary or permanent transition) at a point in the call flow where there was a problem with the speech recognition.
