  • Patent number: 8345253
    Abstract: A system and method for molecule detection uses a surface plasmon resonance (SPR) system with detection spots having fixed nanostructures. An SPR assembly may be combined with a digital microfluidic control system such as an electrowetting-on-dielectric (EWOD) chip. The microfluidic system individually directs sample droplets to different detection spots of the SPR assembly, thus allowing the SPR examination of different samples or sample reactions on the same surface. The nanostructures at the detection spots enhance the sensitivity of the SPR signals.

  • Patent number: 8313966
    Abstract: Semiconductor micro- and nanotubes allow the incorporation of ordered structures such as quantum wells and quantum dots into them providing the potential for ultralow threshold micro- and nanoscale lasers for use in applications such as future ultrahigh-speed photonic systems as well as quantum information processing. According to the invention a means of manufacturing these with high reproducibility, low processing complexity, and at high densities is provided. Also provided is a means of releasing these micro- and nanotubes with low stress and a method of “pick-and-place” allowing micro- and nanotubes to be exploited in devices integrated on substrates that are either incompatible with the manufacturing technique or where the area of substrate required to manufacture them is detrimental to the cost or performance of the circuit.

  • Patent number: 8282898
    Abstract: A process for formulating high purity potassium chloride from a carnallite source. The process takes advantage of solubility differences and saturation levels in a multiple salt system generated upon dissolution of carnallite. In the system, the sodium chloride is kept in solution and the magnesium chloride present in the system is controlled to be in a concentration range of between 12% and 25% by weight. This avoids co-precipitation of sodium chloride with the potassium chloride during crystallization and therefore prevents the sodium chloride from contaminating the potassium chloride. The result is high grade potassium chloride.

  • Patent number: 8263986
    Abstract: Quantitative understanding of neural and biological activity at a sub-millimeter scale requires an integrated probe platform that combines biomarker sensors together with electrical stimulus/recording sites. Optically addressed biomarker sensors within such an integrated probe platform allows remote interrogation from the activity being measured. Monolithic or hybrid integrated silicon probe platforms would beneficially allow for accurate control of neural prosthetics, brain machine interfaces, etc as well as helping with complex brain diseases and disorders. According to the invention a silicon probe platform is provided employing ultra-thin silicon in conjunction with optical waveguides, optoelectronic interfaces, porous filter elements, and integrated CMOS circuitry. Such probes allowing simultaneously analysis of both neural electrical activities along with chemical activity derived from multiple biomolecular sensors with porous membrane filters.

  • Patent number: 8220783
    Abstract: An insulator for use with a steam discharge tube of the type having two parallel rows of oppositely facing steam discharge apertures is disclosed. Two elongate channel sections having elongate channel edges are positioned transversely between the two rows and extend longitudinally along the tube on opposite sides of the tube. Sealing and spacing means serves to seal in spaced apart relationship the channel sections from the tube on respective opposite sides of the tube and provision is also made for securing said sections to the tube when in their desired location. The resultant insulator in assembled form reduces unwanted condensation production from the steam discharge orifices and also due to no use or the reduced use of polymers, the generation of unwanted off-gases.

  • Patent number: 8098969
    Abstract: The invention describes an integrated-photonics arrangement, implementable in a multi-guide vertical integration (MGVI) structure composed from III-V semiconductors and grown in one epitaxial growth run, allowing for the integration of semiconductor optical amplifier (SOA) and PIN photodetector (PIN) structures within a common wavelength-designated waveguide of the plurality of the vertically integrated wavelength-designated waveguides forming the MGVI structure. The integration includes a wavelength filter integrated between the SOA and PIN to reduce noise within the PIN arising from ASE generated by the SOA. In exemplary embodiments of the invention, the wavelength filter is integrated into MGVI structure either within a common wavelength designated waveguide or within the wavelength-designated waveguide.

  • Patent number: 7782226
    Abstract: Communication nodes for use with a wireless ad-hoc communication network are disclosed. In an embodiment of the present invention, the communication node comprises a transducer, which generates a signal in response to an external signal. The ad-hoc network communication is supported in part by static communication nodes, which defined an organized infrastructure network in order to achieve the various functions of the transducers. In another embodiment, the communication node for use with a wireless ad-hoc network does not include a transducer. Such communication nodes are preferred for use with a less structured network with virtually no infrastructure and allow for being used with expanding and contracting networks. Mobile communication nodes mostly support the propagation of signals. However, pseudo-static or static communication nodes are also used in wireless communication ad-hoc networks.

  • Patent number: 7760645
    Abstract: An ad-hoc network is a typically a dynamic collection of nodes capable of communicating therebetween without the aid of pre-established infrastructure. Ad-hoc networks differ from traditional networks in that the topology of interconnections between nodes is inherently dynamic and not fixed. Generally, the routing protocols belong to two groups: proactive and reactive. Proactive protocols attempt to maintain correct and up-to-date routing information at every node. Reactive protocols, in turn, collect necessary routing information only if a pair of nodes are to establish a communication. In accordance with embodiments of the invention a reactive ad-hoc network protocol is disclosed that uses controlled flooding to broadcast packets of information within the ad-hoc network.

  • Patent number: 7747673
    Abstract: A number of items of data from a data source (12) can be processed and then deposited in at least one data destination (16, 17). The data may be image data, text data, numeric data or some other type of data, or a combination of these types of data. The processing of data is controlled by a project definition (14, 71, 101), which includes a plurality of modules selected from a variety of available modules (Tables 1-4). The modules have input and output ports which are interrelated by binding information. One of the modules, when executed, transmits a predetermined message, for example in the form of an electronic mail message.
