  • Publication number: 20140354734
    Abstract: A microfluidic electronic device is disclosed. This microfluidic electronic device may include a separate actuator mechanism from a microfluidic cartridge. The microfluidic cartridge may include a fluid reservoir coupled to a nozzle by a channel, where the fluid reservoir holds a fluid with a solvent and a material in solution, and the microfluidic cartridge may be remateably coupled to the microfluidic electronic device. During operation of the microfluidic electronic device, the microfluidic cartridge supplies fluid to the nozzle via the channel, and the actuator mechanism drives droplets from the nozzle without contact between the actuator mechanism and the fluid. Furthermore, the droplets may be driven from the nozzle onto a substrate without contact between the substrate and the nozzle, and a positioning mechanism in the microfluidic electronic device may accurately position the nozzle relative to the substrate.

  • Patent number: 8724530
    Abstract: A wireless mesh network comprises a first branch of access nodes and a second branch of access nodes. The first and second branches sharing a common access node and each access node is for facilitating wireless interconnection between a device and the network. The minimum separation distance (d1) between an access node in the first branch and an access node in the second branch is greater than K1/?d0, wherein d0 is the separation distance between a transmitting node and a receiving node in the first branch, K is the signal-to-interference ratio (SIR) and ? is the path loss exponential.

  • Publication number: 20140115380
    Abstract: One aspect of the present invention provides a system for failover comprising at least one client selectively connectable to one of at least two interconnected server via a network connection. In a normal state, one of the servers is designated a primary server when connected to the client and a remainder of the servers are designated as backup servers when not connected to the client. The at least one client is configured to send messages to the primary server. The servers are configured to process the messages using at least one service that is identical in each of the servers. The services are unaware of whether a server respective to the service is operating as the primary server or the backup server. The servers are further configured to maintain a library, or the like, that indicates whether a server is the primary server or a server is the backup server. The services within each server are to make external calls via its respective library.

  • Publication number: 20130107792
    Abstract: A relaying device, such as a router, especially those for forming the backbone of a wireless mesh network, comprises a first wireless frontend and a second wireless frontend which are to communicate with each other to facilitate data communication between a first external device and a second external device. The first wireless frontend is to communicate wirelessly with the first external device and the second wireless frontend is to communicate with the second external device using IEEE 802.11 infrastructure mode transmission protocol. Such a relaying device facilitates the cost effective construction of a high speed WMN of say 300 Mbps using infrastructure mode protocol contrary to conventional wisdom.

  • Publication number: 20130004547
    Abstract: The invention provides for anti-pathogen vaccines produced in recombinant bacteria and/or transgenic plants and administered through standard vaccine introduction methods or oral administration. In one embodiment, the vaccine is administered through the consumption of the edible plant as food, or the bacteria administered orally. The present invention also provides a method of using genetically modified microorganisms, such as lactic acid bacteria, including Lactococcus lactis strains, as oral vaccines. In one embodiment, Lactococcus lactis expressing the avian influenza HA gene can be used as an oral vaccine for protection against H5N1 virus infection. In another embodiment, said Lactococcus lactis is administered as an oral vaccine in conjunction with an adjuvant such as cholera toxin B.

  • Publication number: 20120276167
    Abstract: In one embodiment, the present invention provides for an edible mini-capsule form of live, non-persisting, recombinant Lactococcus lactis (L. lactis) vaccine against a pathogen such as the highly virulent influenza H5N1 strain. Enteric coated capsule of the present invention induced high levels of hemagglutinin-specific serum IgG and fecal IgA antibody production after oral administration in mice and chickens, and rendered complete protection against a lethal challenge of H5N1 virus in mice. The present invention thus demonstrates a broadly applicable platform technology for producing and administering edible vaccines against bacterial and viral infections.

  • Publication number: 20120171230
    Abstract: The anti-pathogen vaccine of the present invention is produced in recombinant bacteria and/or transgenic plants and then administered through standard vaccine introduction method or through the oral administration. A DNA sequence encoding for the expression of an antigen of a pathogen is isolated and ligated to a promoter which can regulate the production of the surface antigen in a bacterial or transgenic plant. Preferably, a foreign gene is expressed in a portion of the plant or bacteria, and all or part of the antigen expressing plant or bacteria used for vaccine administration. In a preferred procedure, the vaccine is administered through the consumption of the edible plant as food, or the bacteria administered orally. The present invention also provides a method of using genetically modified microorganisms generally recognized to be edible and/or harmless to animals or humans when ingested, such as lactic acid bacteria, including Lactococcus lactis strains, as oral vaccines.

  • Patent number: 7930675
    Abstract: Operations are performed in EDA tools that operate upon partitions or discrete portions of an electronic design, in which the partitions or discrete portions of the design are expanded to account for effects to/from other areas in the design. Identification is made of the portions of the design that are external to the partitions, and depending upon the type of expected effects, would then be considered during optimization and analysis of the partitions. This is implemented by logically expanding the partition to include consideration of the external portions during timing optimization and analysis. By considering an expanded partition for timing optimization and analysis, it is possible to identify unintended problems caused by the timing optimization at an earlier stage of the design process.

  • Patent number: 7853905
    Abstract: The present invention relates to performing early design for testing (DFT)-aware prototyping of a design. Unlike prior approaches, the improvement analyzes and considers the impact of test structures at a very early stage of the design process. This allows test structures to be considered and addressed in a more efficient iterative and incremental way, which reduces design cycle time and reduces costs.
