Abstract: System, method and program product for determining a cause of a failure of a communication from a source device to a destination device. A preferred route from the source device to the destination device comprises a series of routers in a forward order. First program instructions determine one or more initial routers in the series in the forward order from the source device toward the destination device. A last of the initial routers does not designate a next router in the series in the forward order toward the destination device. Second program instructions determine the series of routers in a reverse order from the destination device toward the source device. Third program instructions determine from the series of routers in reverse order as determined by the second program instructions which router the last of the initial routers should designate as its next router in the forward order toward the destination device, and send a notification as to which router the last of the initial routers should designate as its next router in the forward order toward the destination device.

Abstract: A method and apparatus for implementing a user interface for displaying uterine contraction information is provided.  The contraction signal is processed to derive a sequence of contraction persistence indices. Each contraction persistence index in the sequence is associated to a portion of the contraction signal and conveys whether there is an excess in the rate of contraction in the associated portion of the contraction signal. If there is an excess in the rate of contraction in the associated portion of the contraction signal, the contraction persistence index conveys whether this excess is part of a sustained pattern of excess in the rate of contractions or whether the excess is likely to be transient. The sequence of contraction persistence indices is displayed to a user. Optionally, the graphical user interface is adapted for selectively causing an alarm event based at least in part on the sequence of contractility persistence indices. The method and apparatus may be implemented on any suitable computing platform such as for example desktop computers, laptop computers and personal digital assistants (PDAs).

Abstract: The object of the invention is to provide a papermaking felt, wherein the basic functions are well balanced, which does not have any wet paper web transfer deficiencies due to meandering, or the like, wherein free space of a felt, in which the effect of the press pressure and the hydraulic pressure is scarcely conveyed to the wet paper web, is set to the suitable amount for the initial warming-up period from the start so that the initial warming-up period is shortened, and wherein water squeezing does not deteriorate due to premature decline of water permeability and due to the inability to maintain compressibility by excessive compaction and accumulation of dirt. The object is achieved by a papermaking felt made from a base material 1 and batt layers 2, 3 provided at least on the wet paper web carrying-side layer; wherein a water-absorbing resin 4 is included in the batt layer 2 of the felt. The base material 1 may either have an endless shape, or an open-ended felt may be connected into an endless shape in a papermaking machine. The water-absorbing resin in the felt may either stay in the front batt layer 2 (Fig. 1), or it may also reach the base material 1 or the rear batt layer 3 (Fig.2).
