    Abstract: An example embodiment may include an apparatus comprising a message buffer to receive messages from a voice over packet endpoint if impairments in a media stream pass a threshold, and a processor coupled with the message buffer, the processor to determine changes to media characteristics for the voice over packet endpoint in relation to the impairments and to signal the voice over packet endpoints to adjust media characteristics of the media stream in both directions. Another example embodiment may be a method comprising monitoring a voice over packet media stream for impairments, computing Voice over packet quality metrics based on the impairments, sending or receiving the Voice over packet quality metrics to or from a session peer, when a threshold is crossed for the Voice over packet quality metrics, sending an event notification to a central entity, and changing media characteristics of the voice over packet media stream in relation to the impairments as directed by the central entity.

    Abstract: When a connection is made between a first communication device and a second communication device at a first connector and a second connector, information is generated and exchanged for the purpose of specifying parties to mutual wireless communication. After this information exchange, information is added by a transceiver to data transmitted and received by wireless communication for the purpose of identifying the party to the communication and, by setting the first communication device and the second communication device so that they respond only to data having that data added thereto, one-to-one communication between the first communication device and the second communication device is achieved. One-to-many communication between a first communication device and many second communication devices is also provided.

    Abstract: A thermoplastic elastomer (“TPE”) which is oxygen-permeable is provided with excellent barrier properties against oxygen by melt-blending with a liquid polyisobutene oil plasticizer in an amount insufficient to render the plasticized elastomer tacky. If made tacky, enough detackifier is used to allow the product to be formed into a removable seal. The TPE may be a conventional thermoplastic vulcanizate or a block copolymer of a vinylaromatic compound, typically styrene, and a conjugated diene, typically butadiene or isoprene, or mixtures thereof; the block may be a diblock, triblock or higher block, but the preferred polyblock copolymer is a triblock with styrene end-blocks and a butadiene/isoprene mid-block. Preferably the diene mid-block is hydrogenated to provide a poly(lower)monoolefin mid-block. When the TPE is a TPV, some or all of the mineral oil used to make the TPV processable may also be substituted with the polyisobutene plasticizer. The elastomeric product is particularly useful for sealing elements for containers in which foods, beverages and medical products must be preserved for a long period.
