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.

Clot-specific streptokinase proteins possessing altered plasminogen characteristics, including enhanced fibrin selectivity. The kinetics of plasminogen activation by these proteins are distinct from those of natural streptokinase, in that there is a temporary delay or lag in the initial rate of catalytic conversion of plasminogen to plasmin. Also disclosed are processes for preparing the proteins.

A communication protocol proxy enables a CEBus network to be mapped across a non-CEBus network, thereby allowing a remotely located node (e.g., a controller) to communicate via a non-CEBus network with electronic devices connected to the CEBus network, while still conforming with the EIA/IS-60 protocol requirements. In a preferred embodiment, a proxy node is provided on a CEBus network, wherein the proxy node is also connected to a non-CEBus network, (e.g., a wide area network ("WAN")), such that a remotely located controller on the non-CEBus network may communicate with a device on the CEBus network by transmitting messages to the proxy node over the non-CEBus network. The proxy node then forwards the message to the respective CEBus device over the CEBus network. If the message requires a CEBus Ack message response, the CEBus device transmits a CEBus Ack message to the proxy node, so that it is received within the time interval specified by the CEBus standard. On receiving the CEBus Ack message, the proxy node transmits a non-CEBus standard acknowledge message to the controller, which can be received over an extended time interval. If the message does not require a CEBus Ack message response, the proxy node still transmits a non-CEBus standard acknowledge message to the controller in order to verify receipt of the message.
摘要:
A subscriber network interface for connecting a subscriber premise location to a broadband communication network transporting multiple two-way communication signals, including at least RF analog and RF carrier modulated ATM cells, respectively, includes a coupler for directing incoming communication signals onto, and outgoing signals off of, respectively, at least first and second internal RF communication paths, wherein the first RF communication path includes a bandwidth filter for restricting transmission to, e.g., a CATV broadcast signal, and the second RF communication path is connected to a first modem configured for demodulating and modulating, respectively, the incoming and outgoing ATM cells. A second modem for separately demodulating and modulating, respectively, incoming and outgoing digital baseband signals may also be provided.

Systems and methods for automating an invoice approval process are described herein. Rules are created which are evaluated against a set of attributes. A rules engine is automatically invoked upon receipt of a document in an electronic invoice presentment and payment system. The rules engine determines which rules are applicable to documents received and processed in the system, and applies those applicable rules in a pre-defined sequence.
摘要:
A proppant comprises a particle and a polymeric coating disposed about the particle. The polymeric coating comprises the reaction product of a novolac polyol, an isocyanate, and an azole. The novolac polyol has a number average molecular weight of from about 200 to about 1000 g/mol. A method of forming the proppant comprises the steps of providing the particle, providing the novolac polyol, providing the isocyanate, and providing the azole. The method also includes the steps of combining the novolac polyol, the isocyanate, and the azole to react and form the polymeric coating and coating the particle with the polymeric coating to form the proppant.
