Inventor: SUSAN THERESE LARGIER HARRISON
IPC: C07K14/795
Filed: 2017-08-18
Abstract: An aqueous two-phase separation (ATPS) method for purifying phycocyanin from a phycocyanin-containing solution comprises contacting the solution with an aqueous two-phase mixture which includes a polyethylene glycol (PEG) containing phase and a carbohydrate-containing phase in which conditions are selected to permit the phycocyanin to partition to the lower carbohydrate-containing phase, separating the phases, treating the carbohydrate-containing phase with ammonium sulfate to precipitate the phycocyanin, and recovering the precipitated phycocyanin. Preferably the PEG has a molecular weight of at least 6000 g/mol, and the carbohydrate is maltodextrin. The phycocyanin may be derived from Spirulina.

Title: Device bootstrapping
Inventor: MARKKU LEHTO
IPC: H04W4/70
Filed: 2018-12-03
Abstract: A method for a device 2 to access a remote resource 12. The device receives from a bootstrap server 14 credential data containing a plurality of identifiers associated with connectivity servers 20. The device selects an identifier and authenticates with the associated connectivity server. An administrator server 22 obtains characteristic data, such as security protocol, geographic location, capacity, storage etc., for the connectivity servers 20 and updates a database 24. The administrator server selects a set of identifiers, such as IP address, a FQDN, URL, URI or URN etc., based upon the characteristic data. For example, identifier selection may be based upon reactive scheduling such as when connectivity servers are unavailable/near capacity or on proactive scheduling such as when a maintenance window is due. The identifier set selected may be sent to the bootstrap server. The administrator server may also spawn new connectivity servers in reaction to the characteristic data such as when a server is approaching its capacity. The method may be used for Internet of Things (IoT) devices and the advantage is that resource requests may be load balanced and scaled across the connectivity servers. The connectivity server may be regarded as a relay or gateway device.
