  • Patent number: 9395287
    Abstract: An integrated mobile test system and methods for characterizing in situ stress or strain/deflection—dependent stiffness and bearing capacity enables the testing of engineering properties of natural, compacted, stabilized, and reinforced soils and geo-materials. The mobile test system and associated methods (1) prepare the ground for testing and (2) apply static or cyclic loading to one or more bearing plates of various geometries positioned at the ground surface or below the ground surface to determine both stress and deflection dependent stiffness relationships and the bearing capacity of the soil or geo-material. Optionally, the mobile test system and associated methods (3) apply ground confining stress conditions independent of the bearing plate loading.
    Type: Grant

  • Patent number: 5624065
    Abstract: A safety sport belt having a waist belt and at least one shoulder strap slidingly connected to the waist belt. The waist belt and the strap comprised of a polyester mesh fabric coated with reflective material. A transparent strip is centrally aligned on outer surface of the shoulder strap and the waist belt, which is stitched over a non-transparent strip of a polyester reflective material. The waist belt has a holder for radio and another holder for liquid container and the shoulder strap has a container for holding lock key and a second container for holding a defensive spray applicator.
