Abstract: A method for extracting a target polymer from a contaminated polymer compound, including dissolving the contaminated polymer compound using a given solvent, thereby obtaining a dissolved polymer mixture; microfiltering the dissolved polymer mixture to remove non-soluble impurities having a size larger than a size of the target polymer from the dissolved polymer mixture, thereby obtaining a permeate microfiltered polymer solution; and extracting the given solvent from the permeate microfiltered polymer solution, thereby obtaining a feedstock of the target polymer.

Abstract: A digital mental health ecosystem is presented to address all the mental health disorders and improving the treatment process patients need. Human behavior and physiological factors are studied and proper solution for each individual is presented to caregivers and their respective patients.

Abstract: A remote control door closure operating system is based on a central server with a backend database identifying a collection of controllable doors and a plurality of authorized users and corresponding credentials. A door interface unit is adapted to communicate with an authorized user to supply a live video stream of a respective door and to execute door opening and closing commands from the authorized user. A mobile device has a user application program configured to interact with the central server and door interface unit in order to 1) obtain configuration data, 2) authenticate the authorized user, 3) receive the live video stream, and 4) initiate the door opening and closing commands. Safe operation of the door opening/closing operation is encouraged by maximizing use of video surveillance before and during door operations and by conducting separate security authentications for video streaming and for door operation requests.
