Abstract: Adapters, terminal devices, USB connection devices and charging stations are disclosed. The adapter includes a first port configured to connect to an alternate current (AC) source, a conversion module configured to convert an AC power from the AC source into a direct current (DC) power, a second port configured to connect to a first electronic device and provide power thereto, an uplink interface configured to connect to the first electronic device, a downlink interface coupled with the conversion module to obtain an external power supply therefrom and configured to connect to a second electronic device, and a signal control module arranged between the uplink and downlink interfaces, and configured to control a status of a signal in the downlink interface based on a status of a power supply of the uplink interface.

Abstract: A color electrophotographic recording medium is disclosed that contains a polymeric base film substrate having coated on a side thereof a toner-receptive coating. The coating contains at least one low molecular weight toner-compatible resin segment and at least one high molecular weight thermoplastic resin segment, with the toner-compatible resin segment having a number average molecular weight in the range of about 1,000 g/mole to about 10,000 g/mole, and the thermoplastic resin segment having a number average molecular weight in the range of about 10,000 g/mole to about 500,000 g/mole. Optionally, the toner-receptive coating layer can also contain a polymeric particulate, an anti-static agent, and a surfactant.

Abstract: The present invention is directed to an anti-fogging coating that can be used for anti-fog applications. The coating is transparent, and comprises a hydroxyl group containing polymer, an aluminum containing crosslinker, and a surface active agent containing hydroxyl and/or siloxane groups. Additionally, the coatings possess a T.sub.fog of greater than about 30 minutes and a haze of less than about 5%, and can advantageously be used to provide to glass or plastic substrates an anti-fogging surface.
