摘要： Thermal Acoustic Imaging (TAI) methods and systems are provided for detecting defects in an object. The TAI system may include a plurality of acoustic wave transceivers (AWTs), which are positioned around the object at different locations, and a broadband frequency signal generator, which is coupled to each of the AWTs. The system may further include an acoustic processor configured to utilize the AWTs to gather acoustic data pertaining to the object, process the acoustic data to generate spectral response data, and then process the spectral response data to determine an optimized setup. The optimized setup may include optimized excitation frequencies and optimized inspection positions for positioning a plurality of infrared imaging devices at different locations around the object. A plurality of infrared imaging devices may then be selectively positioned with respect to the object at the optimized inspection positions and utilized to further inspect the object for defects.

摘要： In an example embodiment, there is disclosed herein an apparatus comprising an ingress interface, an egress interface, and a storm controller coupled to the ingress interface and the egress interface. The storm controller is operable to determine whether to forward packets for a traffic flow received at the ingress interface to the egress interface based on a rate over a time period. The storm controller forwards packets for the traffic flow while the rate exceeds a first threshold and is less than a second threshold while a predefined condition exits. The storm controller limits traffic for the traffic flow to the first threshold while the rate exceeds the first threshold and the predefined condition does not exist.

摘要： Embodiments of methods and systems for inspecting a structure for a crystallographic imperfection are provided. In the method, an X-ray wavelength that is particularly susceptible to diffraction by the crystallographic imperfection is identified. Then an X-ray source is provided to emit X-rays in the identified X-ray wavelength. While placing the structure at a sequence of positions relative to the X-ray source, X-rays are directed at the structure in multiple, non-parallel arrays to create sequential patterns of diffracted X-rays. The patterns of diffracted X-rays are digitally captured and communicated to a computer that compares them to locate the crystallographic imperfection. For a surface imperfection, the imperfection may be marked with a target to allow for physical removal.

摘要： A method and apparatus is provided to analyze a dual wall structure having at least one hollow core therein and having the same unknown material sound velocities in walls and in post as well. A transducer is located in at least two different positions with respect to the structure, whereby the transducer propagates an ultrasonic wave toward the dual wall structure. A portion of the ultrasonic wave is reflected back to the transducer. One wave traverses a portion of the dual wall structure that has a core filled with a medium having a known material acoustic property. A second wave traverses a portion of the post that has an unknown material sound velocity. From time of flight measurements of the above mentioned waves, the wall thickness and core shift, if any, can be determined.

摘要： A new and distinct variety of Cymbopogon commutatus grass is provided. The new variety was discovered during a mass selection program that was carried out in India in a cultivated area, and offers significant advantages over a typical plant of the species. More specifically, the new variety exhibits superior drought tolerance, a vigorous perennial growth habit, and lighter green leaves than typically exhibited by the species. The plant produces an essential oil having an enhanced geraniol and geranyl acetate content that is useful to form perfumes and in flavor applications. Asexual reproduction can be readily carried out by the rooting of slips.

摘要： An electromagnetic radiation imaging device comprising an energy absorbing layer overlying an array of thin film transistors (TFTs). each of the thin film transistors incorporates a dual gate. The lower gate provides row selection, while the upper gate of the same device modulates current conducted by the transistor. By utilizing dual gates, a reduction in the number of transistors is achieved over prior art imaging devices, thereby increasing production yield. Furthermore, the use of dual gate transistors provides increased versatility in choosing the bias point of the transistors.

摘要： In an example embodiment, an apparatus with a first interface coupled to a local domain with routers that employ a redundant router protocol, such as Hot Standby Router Protocol (HSRP) and/or Virtual Router Redundancy Protocol (VRRP), and a second interface coupled with a shared domain, such as Virtual Private LAN (Local Area Network) Service (VPLS), and virtual bridging logic coupled with the first and second interfaces. The virtual bridging logic performs packet snooping, filtering and/or provides a proxy service so that the routers employing the redundant router protocol are localized in the local domain, and avoids the routers employing the redundant router protocol from associating with other routers employing the redundant routing protocol that are in another local domain coupled with the shared domain.
