    Abstract: A method provides differentiated quality of service (QoS) by providing adaptive updates to media access control (MAC) layer parameters on a distributed basis. The method includes calculating a failure probability for a transmission over the network, determining a target value for determining a contention window according to a mapped function of the failure probability, and altering the contention window according to a scaling function of the target value. The mapped function and the scaling can provide QoS differentiation. A wireless device ensures fairness in a wireless time slotted network and includes a network interface card (NIC), a network driver interface, a network monitor, a statistics engine, and an adaptive parameter engine for determining a target value for determining a contention window according to a mapped function of the one or more probabilities to enable an alteration of the contention window and provide new parameters for the MAC layer.

    Abstract: A method of filling a plurality of trenches etched in a substrate. In one embodiment the method includes depositing a layer of spin-on glass material over the substrate and into the plurality of trenches; curing the layer of spin-on glass material by exposing the spin-on glass material to electron beam radiation at a first temperature for a first period and subsequently exposing the spin-on glass material to an electron beam at a second temperature for a second period, where the second temperature is greater than the first temperature. The method concludes by depositing a layer of silica glass over the cured spin-on glass layer using a chemical vapor deposition technique.

    Abstract: A multiport testing procedure capable of detecting faults that occur between static random access memory ports as well as traditional cells faults uncovers all possible faults and covers all cells in the memory, without placing architectural constraints on the memory. While executing a test sequence on one port of the memory array, concurrent memory accesses are performed through other ports in the memory. If a fault exists between the port under test and any other port, then the concurrent operations interfere with the values read and/or written on the port under test, and the test uncovers the fault. Thus, for any one test port, the interport test requires only as many memory operations as the associated single port test, keeping test time to a minimum. One embodiment detects faults between the test port, which is a read/write port, and any other port, including read ports and write ports, comprising six passes through the memory. Another embodiment detects faults between write ports, comprising four memory passes. An embodiment of a memory test circuit is disclosed that executes the multiport tests.

    Abstract: A method for producing a standard Raman spectrum of a sample. A source of incident radiation is provided. Means provide an incident beam and a monitor beam from the incident radiation. The incident beam is directed to the sample and a Raman beam is generated from the sample. Spectral data may be collected directly from the monitor beam and the Raman beam simultaneously. The occurrence of a frequency shift in the incident radiation is determined. One spectral measurement is made after the occurrence of the frequency shift, or a first spectral measurement is made before and a second spectral measurement is made after the frequency shift. One or more arithmetic calculations are applied to the single spectral measurement, or the second spectral measurement is subtracted from the first spectral measurement. One or more integral transforms are applied to the resulting spectral measurement data to produce the standard Raman spectrum.

    Abstract: A method for rotating an image using a volatile memory and temporary files includes inputting an image, dividing the input image into portions, loading a divided portion of the input image into the volatile memory, and rotating the loaded divided portion of the input image. The divided portion of the input image is output into a corresponding temporary file, and the loading, rotating and outputting steps performed on the divided portions of the input image are repeated until all divided portions of the input image have been processed. The temporary files are then divided into portions, and one divided portion from each temporary file is loaded into the volatile memory. Finally, the loaded divided portions of the temporary files are assembled, the assembled divided portions of the temporary files are output to a destination image, and the loading, assembling and outputting steps performed on the divided portions of the temporary files are repeated until all divided portions of the temporary files have been processed.
