Abstract: Apparatus for scoring a cover to be applied to a bound stack of sheets to form a book. A base unit is provided having a surface for receiving the cover, an lower die holder disposed below the surface and an upper die holder disposed above the surface. A lower die is supported on an upper surface of the lower die holder and an upper die is supported on the lower surface of the upper die holder. An actuating structure such as a handle, is used to move the upper and lower die between an open position and a closed where the upper and lower die score the cover. The upper die holder is fabrication using a transparent material so that a user can view the upper die and underlying cover to facilitate proper alignment.

Abstract: A device for finding faults in a target system that has a plurality of "LRUs", which are the lowest replaceable units in the target system. The fault finding device receives input data relating to a state of the target system, stores a probability of failure of individual LRUs of the target system, and stores rules, these rules relating conclusions and premises, with at least some of the conclusions identifying a faulty LRU. The device determines a certainty of a conclusion of a stored rule in response to a comparison of the premises of the rule and the input data, and orders the conclusions of the stored rules as a function of both the probability of failure of individual LRUs and the certainties of conclusions of the stored rules.
