  • Patent number: 5598792
    Abstract: A credit card security device which prevents credit card and bank card fraud. The device includes a case with an access door secured by a lock for storing the cards and a detection member within the case for determining an entry into the case when the door is locked. The detection member operates an electromagnet within the case upon the entry. The electromagnet scrambles the code within each credit card's magnetic strip and thereby invalidates the credit cards for future use. The detection member comprises a normally open electrical circuit when the door is closed and locked and includes switches for providing a current flow to the invalidating electromagnet upon the entry. At least one such switch is a normally open pressure switch mounted in wall of the case which closes when the entry to the case is through the wall, thereby providing the current flow to the electromagnet.

  • Patent number: 5289785
    Abstract: A security enclosure comprises a first layer of an insulating material extending over the whole of the area of the enclosure and carrying a linear electrically responsive element on at least one surface. A low tensile strength layer having lower cohesion than adhesion is located between the first layer of insulating material and the electrically responsive element. A second layer of insulating material is adhered to and covers the electrically responsive element. The element is arranged in a configuration on the surface so dividing the surface that attempted penetration of the enclosure changes an electrical characteristic of the element, the change being detectable by an electrical circuit. An attempt to remove the second layer of insulating material to gain access to the element results in breakup of the low tensile strength layer and thus damage to the element and produces a detectable change in an electrical characteristic of the element.

  • Patent number: 4972175
    Abstract: A security enclosure is formed from layers of flexible material. One layer carries a flexible semiconductive line arranged to extend over the whole area of the enclosure. Any interruption of the line by unauthorized opening of the enclosure changes the resistance of the line and so can be detected by a monitoring circuit. Further, two layers of semiconductive fibers also cover the whole area of the enclosure and are separated by an insulating layer. The length of the fibers is greater than the thickness of the insulating layer so that if the enclosure is pierced fibers from one layer will be forced into contact with fibers from the other layer. This will change the combined resistance of the layers and this can also be detected by a monitoring circuit. The two measures can be used separately.

  • Patent number: 4706577
    Abstract: A lockable enclosure is disclosed which may be installed at locations accessible to customers for vending merchandise, dispensing money or receiving deposits, and where a potential attacker would have only a limited period of time to break into the enclosure before the police or security personnel would be able to arrive and intervene against the attacker. The latches and latch bolts of the enclosure have apertures or projections which interlock with mating projections or apertures upon deformation of the sheet metal door or the sheet metal walls of the enclosure when an attacker deforms the enclosure sufficiently to cause damage to the lock or latches. Such interlocking prevents retraction of the latches or latch bolts holding the door closed even if the lock mechanism is completely destroyed or removed by force.

    Abstract: A door-like closure for passageways in high-risk high-security installations includes a multilayer protective plate which has a rather high resistance to mechanical, thermal and chemical damaging influences, but which can be rather easily damaged by the action of explosives. To reinforce the protective plate, a reinforcing grid is juxtaposed therewith at the major surface thereof which faces the interior of the installation so that, when an attempt is made to destroy the protective plate by explosives, the reinforcing grid not only will increase the resistance of the protective plate to damage but also will permit the explosive shockwave and the possible debris of the protective plate propelled thereby to penetrate through the apertures of the grid without causing any considerable damage to the grid. The apertures of the grid have such dimensions that an intruder will not be able to reach through the aperture into the interior of the installation to, for instance, manipulate the lock of the closure.

  • Patent number: 4064799
    Abstract: A print hammer bumper for an on-the-fly impact printer which includes a hammer mechanism having a plurality of print hammers disposed in a linear array. The bumper serves to automatically adjust the forward force of the hammer to the number of paper plys being printed and to dampen the rebound energy of the hammer return stroke. The bumper is in the form of an elongated material having two portions each exhibiting different characteristics. A first portion of the bumper, which is positioned to engage each of the print hammers during their forward printing stroke, exhibits a hardness characteristic such that it readily compresses to adjust the printing force to the number of paper plys being printed. A second portion of the bumper exhibits a low resiliency characteristic and is positioned to engage the hammers upon their return or rebound stroke so as to absorb the hammer rebound energy, thus preventing character overprint by a rebounding hammer again striking the paper.
