  • Publication number: 20070117483
    Abstract: Fabric laminates having superior resistance to penetration of fragments, such as shrapnel. The fabrics are formed of high-strength fibers consolidated with from about 7% to about 15% by weight of an elastomeric matrix composition, and in combination with protective layers of a polymer film on each surface of the fabric. The fabrics achieve a significant improvement in fragment resistance compared to fabrics of the prior art, while also maintaining excellent ballistic resistant properties.

  • Publication number: 20060271884
    Abstract: Documents are grouped into a plurality of subjects. For documents associated with each subject, a document hierarchy is established that includes a plurality of hierarchical levels. A three-dimensional landscape defined by x, y and z orthogonal axes is displayed on a screen, and a plurality of document stacks are arranged in the landscape. Each document stack in the landscape corresponds to a subject, and has a plurality of layers arranged perpendicular to the length of the stack. Each layer in each document stack corresponds to one of the hierarchical levels of the hierarchy established for the subject corresponding to the stack. Images representing documents assigned to each level of the hierarchy are displayed in the layer of the stack corresponding to such level. A user navigates among the document images displayed in the landscape using a cursor.

  • Patent number: 6991850
    Abstract: An improved load leveling yarn has a force-displacement profile that maintains desirable properties of previously known yarns (as exemplified in U.S. Pat. No. 5,830,811), but exhibits a lower elongation at a stress that is greater than the IBS but less than or equal to 1.8 grams/denier. Especially preferred yarns are produced from PET with an IV of greater than 0.9 and epsilon caprolactone (at a ratio of about 90:10) under copolymerization conditions that allow reaction of at least 95% of the added epsilon caprolactone. Such yarns can then be formed into a web to form specific products, and especially seat belts.

  • Patent number: 5539805
    Abstract: A voltage detection circuit, in conjunction with a power supply system for ringing voltage generation in a remote telecommunications unit, monitors the operating voltage level of the remote unit and, when an undervoltage condition is detected, causes a ringing reference-signal generator to collapse the reference (AC) sine wave into a fixed (DC) state and holds it in this state for a preselected time, thereby substantially reducing the ringing-signal current load and allowing the operating voltage level to restore. The features of the invention allow for continued processing of calls in progress and for incoming call completion during an undervoltage condition. The increased reliability and integrity of the power supply system allows for extended power supply feeder distance to the remote telecommunications unit.
