摘要： A porous silicon structure is stabilized by anodically oxidizing the structure and then subjecting it to chemical functionalization to protect non-oxidized surface regions, preferably in the presence of 1-decene under thermal conditions. This process creates a protective organic monolayer on the surface of the structure, rendering it highly stable.

摘要： Methods and systems consistent with the present invention identify a repeating content in a data stream. A hash function is computed for at least one portion of a plurality of portions of the data stream. The at least one portion of the data stream has benign characters removed therefrom to prevent the identification of a benign string as the repeating content. At least one counter of a plurality of counters is incremented responsive to the computed hash function result. Each counter corresponds to a respective computed hash function result. The repeating content is identified when the at least one of the plurality of counters exceeds a count value. It is verified that the identified repeating content is not a benign string.

摘要： The present invention relates to a method and apparatus based on Bloom filters for detecting predefined signatures (a string of bytes) in a network packet payload. A Bloom filter is a data structure for representing a set of strings in order to support membership queries. Hardware Bloom filters isolate all packets that potentially contain predefined signatures. Another independent process eliminates false positives produced by the Bloom filters. The system is implemented on a FPGA platform, resulting in a set of 10,000 strings being scanned in the network data at the line speed of 2.4 Gbps.

The probe includes a connector adapted to couple to the DUT, at least one output measurement port configured to connect to a measuring device for measuring the CM voltage, and at least one differential pair cable connected to a connector and to a at least one measurement port for coupling a differential I/O signals to a measurement port. According to a second embodiment, the present invention provides a voltage probe for measuring CM voltage of a DUT having differential I/O signals while the DUT is simultaneously connected to an auxiliary equipment. According to a third embodiment, the present invention provides a method for measuring EMI from a DUT. A CM voltage probe is interposed between the DUT and an EMI measurement device. The CM voltage is measured at an measurement port of the voltage probe. The measured CM voltage is compared to a limit for EMI.

摘要： A solar-powered airfield light provides high angle light up to about 90°. A solar panel is mounted atop the enclosure but does not overlie a curved transparent shoulder extending upward from the transparent generally cylindrical side walls of the enclosure. An optical element within the enclosure surrounds an LED light source so as to direct light emanating from the LED in two preferential beams, one directed to the shoulder and the other directed to the side walls. A portion of the light impinging on the curved shoulder is redirected to high angles to comply with high angle light requirements for airfield lights.

摘要： A solar powered device and a method of operating such a device to allow it to receive and store information about its physical location, from which it can determine the minimum expected solar energy levels that will be available to it. Based on the minimum expected levels, the device then limits its configurable settings to preferably enable only those configurations having maximum energy demands that can be met or exceeded by the minimum expected energy levels.
