  • Patent number: 8099218
    Abstract: A method of operating a paving system includes establishing a plan for paving a work area which is based on a positional temperature model. The method further includes receiving temperature data for paving material and comparing the temperature data with data predicted by the positional temperature model. Operation of the paving system is adjusted where actual data differs from model predicted data. A paving system and control system are provided having an electronic control unit configured to compare electronic temperature data with a positional temperature model for paving material. The electronic control unit can control machines of the paving system based on comparing actual data with model predicted data, and can further update either or both of a plan for paving a work area and the positional temperature model itself based on differences between actual data and model predicted data.

  • Patent number: 7794808
    Abstract: A typical inventive embodiment describes a tubular shape and comprises a rigid outer layer, an elastomeric middle layer and a rigid inner layer. The elastomeric material is a strain-rate-sensitive polymer (e.g., polyurethane or polyurea) having a Young's modulus of approximately 700-1000 psi at 100% strain, and strong strain-rate-sensitivity in approximately the 103/second-106/second range. By the time that the projectile reaches the rigid inner layer, a projectile that impacts the three-layer system (commencing at the rigid outer layer) is structurally and kinetically diminished in its destructiveness by the rigid outer layer together with the elastomeric middle layer. Furthermore, the elastomeric middle layer becomes more rigid during a brief period in which it absorbs energy from the projectile, then again becomes elastic in a manner formative of a membrane covering the rigid inner layer. The elastomeric membrane tempers leakage if rupturing of the rigid inner layer has occurred.
