Abstract: A method for selecting a codec pair includes obtaining a first performance metric indicating a condition of a first network connected to the network node via a first communication interface, the first network including a first endpoint. A second performance metric indicating a condition of a second network connected to the network node via a second communication interface is obtained. The second network includes a second endpoint. A codec selection model is generated or updated based on the first and second performance metrics. A first codec is selected from a plurality of codecs compatible with the first endpoint based on the codec selection model. A second codec is selected from a plurality of codecs compatible with the second endpoint based on the codec selection model. The first and second codecs are used to communicate a portion of a communication session between the first endpoint and the second endpoint.

Abstract: Embodiments provide systems, methods, apparatus, and computer program products for selecting the codecs that each endpoint will use in a call in order to optimize the utilization of at least one internal resource of a network component. The network component receives a call invite from a first endpoint that identifies available codecs. The network component determines what codecs are available to the second endpoint and determines what codec pairing will have the least impact on at least one identified internal resource of the network component. The network component sends call set-up information to the first endpoint that identifies the selected codec or list of codecs for the first endpoint, and call set-up information to the second endpoint that identifies the selected codec or list of codecs for the second endpoint.

Abstract: Methods, systems, and non-transitory computer readable media for estimating speech energy of an encoded bit stream based on coding parameters extracted from the partially-decoded bit stream are disclosed. In an embodiment, a disclosed method includes receiving a CELP-encoded bit stream, partially decoding the bit stream, and estimating the speech energy of the bit stream based a set of four or fewer CELP parameters extracted from the partially decoded bit stream. In another embodiment, a disclosed method includes receiving a CELP-encoded bit stream, partially decoding the bit stream, extracting at least one CELP parameter from the partially decoded bit stream, and estimating the speech energy of the bit stream based on the extracted at least one CELP parameter without calculating a linear prediction coding (LPC) filter response energy.

Abstract: An improved extendable and collapsible container has a plurality of telescoping sleeves adapted to interlock with one another to form a desired volume. A base member attached to a bottom most sleeve and adapted to house the sleeves when the container is collapsed, and adapted to form a base of the container when the container is extended. A removable cap member attached to a top most sleeve and adapted to enclose the volume when the container is extended, the cap member includes a closable opening therethrough adapted to allow a substance to pass from the volume inside the container outward therefrom when desired. A sleeve locking mechanism adapted to lock the sleeves in respective positions when a desired volume is formed and unlock the sleeves from their respective positions when it is desired to collapse the container.

Abstract: A water table used for cutting metal is comprised of an array of slat bars, a floor part below the array of slat bars, a movable platform further below the floor part. The movable platform, by the use of height changing means, will move in order to change the volume available inside the water table which results in the actual lowering or raising of the level of water inside of the water table.
