Patent number: 10371692Abstract: A method of forming a nanopore in a lipid bilayer is disclosed. A nanopore forming solution is deposited over a lipid bilayer. The nanopore forming solution has a concentration level and a corresponding activity level of pore molecules such that nanopores are substantially not formed un-stimulated in the lipid bilayer. Formation of a nanopore in the lipid bilayer is initiated by applying an agitation stimulus level to the lipid bilayer. In some embodiments, the concentration level and the corresponding activity level of pore molecules are at levels such that less than 30 percent of a plurality of available lipid bilayers have nanopores formed un-stimulated therein.Type: GrantFiled: April 14, 2017Date of Patent: August 6, 2019Assignee: GENIA TECHNOLOGIES, INC.Inventors: Roger J.

Patent number: 10360807Abstract: In non-limiting examples, media can be created from any type of existing content. An exemplary media may be an assignment media (e.g. document) that is created for educational purposes. Content that is unassociated with a learning management system may be accessed. Input may be received requesting creation of an assignment media based on the accessed content. The request may be received through a learning management application, where the assignment media may be created based on the received input. Creation of an assignment media automatically associates the assignment media with a user account of a learning management application and a distributed network storage that corresponds with the user account. In some examples, the created assignment media may comprise one or more portions of the accessed content. The created assignment media may be accessed through the learning management application. Other examples are also described.Type: GrantFiled: October 27, 2016Date of Patent: July 23, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Fan Zhang, Randy Davis, Ashwini Purohit
