  • Patent number: 11176830
    Abstract: A vehicle location tracking system comprises a plurality of transceivers, a coordinator, and a plurality of identification tags. The plurality of identification tags are coupled to a fleet of vehicles to be tracked. The transceivers measure the strength of a signal emitted by an identification tag coupled to a vehicle and communicate the measured signal strength to the coordinator. The indoor vehicle location tracking system estimates the location of the vehicle based on the measured signal strength.

  • Patent number: 4961989
    Abstract: A coherent fire-resisting flexible sheet material for aerospace applications is provided consisting of a layer of ceramic fibers embedded in a silicone rubber compound. The ceramic fibers may be in the form of a plain woven fabric of monofilament fibers of alumino-boro-silicate and the silicone rubber compound can be a curable non-foaming methylphenyl silicone compound. In production, the silicone compound is applied to the fabric as a thixotropic paste in sufficient quantity to entirely cover and impregnate the fabric and is forced through the interstices of the fabric by the application of pressure. The coated and impregnated fabric is then placed in an oven to cure the silicone compound.
