Abstract: This invention involves a cost effective antiviral plastic film with variable physical properties, comprising of at least one thinner surface layer to minimize the amount of the expensive copper nano-powders required to render the film to be antiviral, and one thicker substrate layer with variable physical properties and thickness. The plastic film is made using a co-extrusion cast film or a blown film process so that the antiviral surface layer and the substrate are joined together as they are made into a multilayer film. The physical properties for the plastic film can be varied by using different kinds of polymeric materials such as PE, PP, PVC, Nylons and others. Its low cost combined with variable physical properties make our invented film suitable for making a wide variety of affordable and safer protection products against the COVID-19.

Abstract: The present invention provides a system in which a user can login to a World Wide Web server's (Web) application page and get help on the features assigned to an instrument such as a telephone or a service such as a voicemail system that is a configurable asset specifically assigned to that user. The on-line help is preferably kept in text and/or multimedia format on a server. The entity or that is displaying the help information is preferably a different entity than the service provider device that is providing the functionality or service to the asset. A synchronization process occurs so that thew server providing the Web-based help has a database of features assigned to the user as well as other information about the user.
