A scan test architecture is implemented. The scan test architecture provides a method of performing scan test of unbalanced scan chains. The scan test architecture generates a control signal (i.e., masking signal) to mask bits in an unbalanced scan chain. In one embodiment, the control signal is generated with a logic gate, a comparator, and a counter.

The present invention provides structures and devices comprising conductive segments and conductance constricting segments of a nanowire, such as metallic, superconducting or semiconducting nanowire. The present invention provides structures and devices comprising conductive nanowire segments and conductance constricting nanowire segments having accurately selected phases including crystalline and amorphous states, compositions, morphologies and physical dimensions, including selected cross sectional dimensions, shapes and lengths along the length of a nanowire. Further, the present invention provides methods of processing nanowires capable of patterning a nanowire to form a plurality of conductance constricting segments having selected positions along the length of a nanowire, including conductance constricting segments having reduced cross sectional dimensions and conductance constricting segments comprising one or more insulating materials such as metal oxides.

A nitride semiconductor is grown on a silicon substrate by depositing a few mono-layers of aluminum to protect the silicon substrate from ammonia used during the growth process, and then forming a nucleation layer from aluminum nitride and a buffer structure including multiple superlattices of Al_RGa_(1-R)N semiconductors having different compositions and an intermediate layer of GaN or other Ga-rich nitride semiconductor. The resulting structure has superior crystal quality. The silicon substrate used in epitaxial growth is removed before completion of the device so as to provide superior electrical properties in devices such as high-electron mobility transistors.

A method for distributing keys for encrypted data transmission in a preferably wireless sensor network. Initially nodes store a subset of keys from a set of keys. A powerful sink node located in the centre of the wireless sensor triggers the key election procedure and sensor nodes choose from a locally broadcasted key-ID list one key to be stored on each node. All other initially stored keys are subsequently deleted. The process is iteratively until the edge of the network is achieved. Such key pre-distribution suits for the encryption of reverse multicast traffic to the sink node which is the pre-dominant traffic pattern in wireless sensor networks.

A film construction (320) includes a broad band reflective polarizing film (312) that may be immersed in an ultra low refractive index medium (322, 324). The reflecting polarizing film is characterized by a pass axis and a block axis, and its reflectivity for white light of the pass state polarization increases with increasing incidence angle to provide a compressed or narrowed viewing cone in one or two planes.

A method and device for selective relaying in a communications network having a plurality of sources, a relay, and a destination. The method includes the following steps: the relay receives messages transmitted respectively by the sources in order to obtain an estimate of the messages; the relay detects errors in the estimated messages; the relay transmits a representative signal to the destination, the signal being representative of only those messages for which no error was detected and resulting from a non-bijective surjective function applied to the messages detected without error, the function including interleaving and encoding; and the representative signal being transmitted by the relay to the destination with a check signal indicating which messages are represented in the representative signal.

A system and method for feeding a composite fluid to a mold for casting a reinforced composite structure, such as a rotor blade for a wind turbine are provided. The system includes a first feeding unit for feeding a first flow of composite fluid to the mold through a first mold inlet, and a second feeding unit for feeding a second flow of composite fluid to the mold through a second mold inlet. The first flow of composite fluid and the second flow of composite fluid are individually controllable.

The invention relates to the separation of microparticles by means of a nozzle (12) for the release of a separating stream (20), comprising at least one enveloping fluid and microparticles entrained Therein, with a vibration generator (18), for the dispersion of the separation flow (20) into a droplet flow (20′), with a deflector device (24), for separation of the droplet flow (20′) into a through flow (20A) and at least one side flow (20B, 20C, . . . ), depending on signals from an analytical device (38). Said analytical device (38) is provided for the analysis of the microparticles(s) contained in the droplets and to control the deflector device (24). Also provided is a protective chamber for product and personnel protection, in which at least the nozzle (12), the oscillation generator (18) and the deflector device (24) are arranged. The analytical device is arranged essentially outside the microbiological safety cabinet (200), whereby, according to the invention, the protective chamber is part of a microbiological safety cabinet (MSW 200), in particular with a laminar throughflow, with a clean chamber (34) and with a monitoring device (22), provided in a side wall, in particular in the back wall (32) of the microbiological safety cabinet (200), through which the signals of the microparticles arising from the separating stream (20) are supplied to the detectors of the analytical device (38), arranged outside the microbiological safety cabinet (200).
