  • Patent number: 11503819
    Abstract: Systems and methods for providing a combined mosquito staging and dissection system are disclosed. The system can include a mosquito staging subsystem; a robotic pick-and-place station; and a dissection, extrusion, collection, and disposal subsystem. The subsystems can include one or more stations to provide orientation, decapitation, extrusion of salivary glands, and disposal of carcasses of the mosquitoes. The resident live sporozoites from the salivary glands can be used to produce Plasmodium SPZ-based vaccines.

  • Publication number: 20200380482
    Abstract: The invention relates to an electronic exchange for bill pay transactions via an interbank information network (IIN) architecture. An embodiment of the present invention provides a marketplace for secure collection, assignment and distribution of payments and data from Bill Pay to Lockbox providers. This eliminates paper checks, resulting in faster deposit into client accounts, better management of payment exceptions, and reduction in overall operating costs. The IIN architecture provides a global platform using Blockchain technology for real-time interconnected flow of information that address immediate pain points across the financial industry and enable new services. With an embodiment of the present invention, a distributed network may streamline process for resolving compliance based inquiries and provide global beneficiary account validations.
