Abstract: A temperature sensor is described that includes a base, a first set of posts attached to the base having a first coefficient of thermal expansion, a second set of posts attached to the base and having a second coefficient of thermal expansion, and two substantially parallel conductive plates forming a capacitor. The first of the conductive plates is fixed to the first set of posts and the second of the conductive plates is fixed to the second set of posts. Temperature changes cause the first set of posts and the second set of posts to elongate at different rates, thereby changing a distance between the conductive plates and therefore the resulting capacitance. A system and method are also described for determining resonant frequency associated with the sensor which correlates to the temperature at the sensor when multiple sensors are networked across a system.

The system including a structure substantially defining an enclosure, a reflective interior of the enclosure configured for the reflection of radio signals, at least one conveyor belt that transports the objects through the structure, at least one RFID reader panel inside the structure, wherein the at least one RFID reader panel transmits a radio signal into the interior of the structure such that the radio signal will reflect off of the interior of the structure to increase a probability that the RFID tags associated with the objects that enter the structure are read, and an operator terminal that receives and stores information regarding read RFID tags from the at least one reader panel.

Abstract: A system and method for collecting a plurality of metrics during a single run of a computer program. The mechanism of the present invention initializes a plurality of counters to count events associated with metrics of interest. The mechanism of the present invention then counts the occurrence of events associated with metrics of interest during a single execution of a computer program. When a branch has been taken, a trace record is generated for the branch taken, wherein the generated trace record contains a count of events associated with the metrics of interest for the branch taken.

Abstract: A method, apparatus, and computer instructions in a processor for associating a data type with a memory location. The type is associated with a location by means of metadata that is generated and manipulated by hardware instructions that are typically generated by a compiler as it generates the other instructions that comprise the machine code version of a program. A determination is made as to whether a data value about to be stored is of the required data type for that location. The hardware indicates an error condition if the types do not match.

Abstract: A system and method for collecting a plurality of metrics during a single run of a computer program. The mechanism of the present invention initializes a plurality of counters to count events associated with metrics of interest. The mechanism of the present invention then counts the occurrence of events associated with metrics of interest during a single execution of a computer program. Responsive to a determination that a counter in a plurality of counters has generated an interrupt, the interrupt is rerouted to an interrupt handler, wherein the interrupt handler generates trace records comprising trace information corresponding to the interrupt. The mechanism of the present invention then generates profiles for the trace records, wherein the profiles differentiate the trace records based on the metric type associated with each trace record.

Abstract: An engine exhaust nozzle comprises a plurality of CMC staves attached to one or more support rings arranged axially. The support rings provide a circumferential load path between the staves and for attaching the exhaust nozzle to the metallic engine components. The staves are fixed to the support rings with a spacing intended to accommodate for relative movement due to the difference in CTE for the CMC and metallic components and due to thermal gradients through the wall thickness. The resulting apparatus is lightweight, relieves the nozzle of thermal stresses, and is easier to manufacture and repair.

Abstract: A method, a system, an apparatus, and a computer program product are presented for loading LDIF ((Lightweight Directory Access Protocol (LDAP) Data Interchange Format) data into a directory. A single reader thread reads entries from an LDIF file; each entry is associated with a priority value, e.g., the priority value for an entry may be based on the number of delimiters in the distinguished name within the entry. Multiple loading threads concurrently add the entries into an LDAP directory in accordance with their associated priority values. The entries are added to the LDAP directory in an order of highest indicated priority to lowest indicated priority; entries that are associated with priority values that indicate equal priority are considered to be equivalent for the purposes of ordering the entries, so entries that have equal priority may be added to the LDAP directory in any order.

Abstract: A method and apparatus for averaging out variations from run to run of a computer program are provided. With the apparatus and method, call trees are generated for two or more executions of a build of a computer program. The apparatus and method perform a “tree-addition” operation in which the two or more call trees generated during runs of the computer program are added to one another to thereby accumulate statistics for each call in the call trees. These statistics may then be divided by the number of runs whose tree data structures are being accumulated. In this way, an average of the tree data structures is generated. In addition, any portions of the tree data structure that are due to asynchronous events are averaged out so that their relative affect in the resulting tree data structure is minimized.

Abstract: A method and apparatus for identifying differences in runs of a computer program that are due to changes in the code of the computer program. With the apparatus and method, call trees are generated for two or more builds of a computer program. The apparatus and method perform a “tree-subtract” operation in which the two or more call trees generated during runs of two or more different builds of a computer program are subtracted from one another to identify build to build differences in the execution of the computer program. From the resulting tree, portions of the runs of the different builds of the computer program where the resource utilization of the computer program has not changed are easily identifiable. Moreover, portions of the runs of the different builds of the computer program where there are improvements or regressions in resource utilization of the computer program may be easily identifiable.

Abstract: The present invention provides an optical device which comprises a light guide incorporating a Bragg grating. The apparatus also comprises a moveable wall portion which is coupled to the Bragg grating so that a movement of the wall portion causes a force that effects a change in strain of the Bragg grating and thereby effects a change in an optical period of the Bragg grating. A temperature related change in the optical period of the Bragg grating is reduced by a temperature related change in the force on the Bragg grating by the moveable wall portion.

Abstract: The present invention provides an apparatus for pressure sensing. The apparatus comprises a light guide, a Bragg grating incorporated into the light guide and a moveable wall portion. The moveable wall portion has opposite first and second sides and is being positioned so that a change in pressure at one of the sides relative to a pressure at the other side will move the moveable wall portion. The moveable wall portion is coupled to the Bragg grating so that the movement of the moveable wall portion causes a force on a side of the Bragg grating. The force has a component that is transversal to the Bragg grating and effects a change in strain of the Bragg grating and thereby a change in an optical period of the Bragg grating.

Abstract: A method, apparatus, and computer instructions in a processor for checking assertions. A determination by the processor is made as to whether metadata for an assertion is associated with the memory location, in response to detecting a change in data in a memory location. The data to the assertion is compared by the processor, in response to the metadata being associated with the memory location. An error is generated by the processor if the assertion is invalid, with respect to the data. The processor checks the assertions for validity.
