A method of creating a hydrophobic polymer membrane surface includes depositing a polymer material onto a heated carrier, using the heated carrier, transporting the polymer material past an electrode field generator, generating an electric field adjacent the carrier, using the electric field to form a pattern in the polymer material to form a patterned polymer membrane, rinsing the patterned polymer membrane in a first bath, and setting the pattern into the patterned polymer membrane in a second bath.

The present disclosure is directed to a film formulation that resulted in a substantially non-migratory cold seal release film with improved blocking resistance. Specifically, the multilayered biaxially oriented polypropylene film can include a core layer of polypropylene homopolymer; a first outer layer on one side of the core layer that can be suitable for sealing, printing, or coating; and a second outer layer on the opposite side of the core layer that is a blocking resistant layer comprising thermoplastic polymers which reduce blocking tendency.

A disclosed digital media device operational at user premises to receive media signals from a media source for presentation via endpoint devices such as a television display. The digital media device can include gateway and digital media management functionality and can be referred to as a gateway and digital media device. The device offers application services obtained over a wide area network and a user premises network. The digital media device may form a composite signal from the media signal and application service information, for example, for a composite audio and/or video signal for television type presentation to the user. The digital media device may receive a selection signal based on the presentation, for transmission to the application service provider device or to the media source. The media device also offers a GUI presenting a moveable arrangement of icons for selectively accessing application services.
