  • Patent number: 9923771
    Abstract: A system includes a media optimizer that adaptively generates and transmits a modified manifest file based on an original manifest file corresponding to an associated media asset from a content provider in response to a media content request from a client for the associated media asset. The original manifest file specifies bitrates. The media optimizer extracts parameters associated with the media content request and applies bitrate policies based on the extracted parameters to adaptively modify the original manifest file to generate the modified manifest file. The media optimizer is further configured to transmit the modified manifest file to the client for selection by the client of a bitrate associated with delivery of the associated media asset.

  • Patent number: 9864103
    Abstract: Hydrogel contact lenses that are derived from a polymerizable composition including at least one hydrophilic monomer and at least one phosphine-containing component are described. The hydrogel of the contact lenses can be a silicone hydrogel or a non-silicone hydrogel. Use of polymerizable compositions comprising a phosphine-containing component can be cured under both inert and air atmospheres, and can be used to form hydrogel contact lenses having improved shape retention properties, having improved resistance to discoloration. Batches of hydrogel contact lenses and methods of making hydrogel contact lenses are also described.

  • Patent number: 9628442
    Abstract: At a network device through which client devices communicate with a network, a database is created that maps Internet Protocol (IP) addresses each to a respective trust metric for a domain name associated with the IP address. An IP packet sent from a client device to the network and that indicates a destination IP address for a network-accessible resource associated with a domain name is intercepted. Using the destination IP address in the intercepted IP packet, the domain name trust metric mapped to the destination IP address is retrieved from the database. IP packets received from the destination IP address are processed based on the retrieved domain name trust metric and a predetermined trust metric criterion.

  • Patent number: 8343768
    Abstract: The effectiveness of an oxidative sterilization process is determined by exposing a known amount of a primary amine or aldehyde indicator chemical to an oxidative germicide. The oxidative germicide reacts with the indicator chemical. The amount of indicator chemical remaining after exposure to the germicide is determined by reacting the indicator chemical with a dye precursor chemical to form a colored product. The amount of indicator chemical remaining is determined from the intensity of the color of the colored product. The amount of indicator chemical remaining on the substrate is a measure of the effectiveness of the germicidal treatment. The dye precursor is an aldehyde when the indicator chemical is a primary amine and a primary amine when the indicator chemical is an aldehyde. An integrator for determining the effectiveness of the germicidal process includes an indicator chemical, where the indicator chemical is a primary amine or an aldehyde.
