Abstract: A system for implementing time stamp related features in a real time stamp distribution system is discussed. The distribution system derives a real time stamp (RTS) at a master timekeeping network element and distributes the RTS to associated network elements by way of a number of distribution techniques. Under certain network conditions, the real time stamp may not reach one or more of the network elements at the valid real time. In the present system, the network elements are able to derive a local time based on timing information recorded at the network element. Thus the system can detect an error in the time stamp delivered to a network element and can correct the time stamp utilizing a local time stamp feature.

Abstract: The method for the non-disruptive monitoring of a packet flow from a target point (e.g., a specific port/VPI/VCI) to a counterpart point in a packet switch having one or more interface devices, connected to an internal bus, for servicing the target point, the counterpart point and a monitor test access connection (TAC) point comprises the steps of: (a) configuring the device servicing the TAC point to retrieve from the bus packets addressed thereto which use a multicast addressing scheme for routing packets from the target point to the counterpart point and from the target point to the monitor TAC point; (b) configuring the device servicing the counterpart point to additionally retrieve the multicast packets from the bus; and (c) configuring the device servicing the target point to address packets received thereat to the counterpart point and the monitor TAC point using the multicast address scheme only after step (b) is completed.

Abstract: A lymphatic pump apparatus for use under the thoracic cage of a human patient in a supine position. The apparatus comprises a mat which supports a pair of longitudinal lifting members positioned to be parallel to and on opposite sides of the spine under the angle of the ribs. The apparatus provides intermittent rib cage excursion, or anterior displacement of the ribs, to assist and increase lymphatic flow. Enhancement of lymphatic flow is beneficial in numerous disease states characterized by capillary leak and abnormal excursion of fluids and proteins into the interstitial spaces.

Abstract: A real time stamp distribution system for multi-element/multi-processor networks. A master network element derives a real time stamp (RTS) from a source and distributes the RTS to the remaining network elements. A combination of distribution methods are discussed including a dedicated hardware connection, hardware and software messaging and a method wherein a high precision stamp is derived from an oscillator located on each network element. In one embodiment the system has a drift adjustment feature to compensate for a system time stamp drift relative to the real time. Redundancy can be provided by employing multiple master timekeeper elements. The RTS in one application has three timing components; a high precision portion; an intermediate precision portion and a low precision portion. The intermediate portion can be implemented using shifter based counters such as a linear feedback shift register.
