Abstract: A self-extracting service module for piping infrastructures comprises a platform on which is mounted equipment for controlling and or monitoring the flow of liquid or gaseous media throughout the piping infrastructures. A first remote-controllable pipe coupling system is interconnected with the equipment inlet and a second pipe coupling system is interconnected to the equipment outlet. The platform is attached to actuators positioned near each corner of the platform. The actuators cooperate with at least one pressure-driven device. The service module is extracted from the piping infrastructure by isolating the equipment from the flow of liquid media after which, the pipe coupling systems are remotely disengaged from the piping infrastructure inlet and outlet. The actuators are operated to move the platform from within the piping infrastructure to a position where service work is easily performed on the equipment without the attendant hazards and constrictions associated with confined spaces.

Abstract: An asynchronously pipelined SDRAM has separate pipeline stages that are controlled by asynchronous signals. Rather than using a clock signal to synchronize data at each stage, an asynchronous signal is used to latch data at every stage. The asynchronous control signals are generated within the chip and are optimized to the different latency stages. Longer latency stages require larger delays elements, while shorter latency states require shorter delay elements. The data is synchronized to the clock at the end of the read data path before being read out of the chip. Because the data has been latched at each pipeline stage, it suffers from less skew than would be seen in a conventional wave pipeline architecture. Furthermore, since the stages are independent of the system clock, the read data path can be run at any CAS latency as long as the re-synchronizing output is built to support it.
