Abstract: A cover is fitted to an aperture in an enclosure. A biasing mechanism is connected to the cover to mechanically bias the cover in an open position. An adhesive member is disposed around the aperture to retain the cover in a closed position against the bias of the biasing mechanism. A release mechanism effects release of the cover from the adhesive member by diminishing adhesion thereof in response to an open command signal.

Abstract: Grade enhancement of mint grade and proof-like coins is disclosed based on a determination of an indication that the coin was a “first strike” coin. First strike is defined by the first 10% or less of coins struck by the same die and may be determined by the location of a physical attribute of the coin present in at most 10% of similar coins struck by the same die. First strike in proof-like coins may be determined by frosted white cameo.

Abstract: A system (10) for cataloging and detecting network faults, includes a communication interface (12) for receiving a fault message from a network. A parser (14) is connected to the communication interface (12). The parser (14) parses the fault message for an event type. An associative database (16) is connected to the parser (14) and stores a tally for the fault message.

Abstract: A contactless detection system for detecting the movements of the switch points of a railroad switch and stock rail of a railroad switch/point having a transformer for detecting or sensing the position of the switch points, the transformer having a core linked to the switch points, and further having a primary coil and a pair of secondary coils wound around the core; and an electronic interface means for receiving signals from the secondary coils responsive to, and corresponding with, the positioning of the switch points.

Abstract: A tamper-proof coin case is presented. The coin case comprises a unitary assembly having a first substantially planar member which has a first element of an interlocking means disposed circumferentially thereabout, the first planar member being joined to a second substantially planar member having a second element of the interlocking means whose shape is complementary to the first element and which is disposed circumferentially about the second planar member. The unitary assembly has a first interior retention zone shaped such that a coin can be retained within the first interior retention zone, a second interior retention zone shaped such that at least one photograph of the coin can be retained within the second interior retention zone and a third interior retention zone shaped such that a certificate for the coin can be retained within the third interior retention zone.
