Abstract: Methods, systems, and devices are provided for the repair of a monolithic array comprised of elements. The method includes processes to identify damaged sections containing damaged elements in a damaged array, where each section contains contiguous elements with at least one damaged element; identify good sections in donor arrays that contain at least as many contiguous elements as those in each corresponding damaged section; removing the damaged sections from the damaged array; removing the good sections from the donor arrays; preparing the damaged array to receive the good sections; affixing the good sections to the damaged array; and testing the damaged array to ensure its characteristics are the same as those of an undamaged array.

Abstract: A low pressure tire including a torus of flexible, substantially inelastic material. The material will not deform at a temperature of about 225° F. The torus includes an inner diameter surface for engaging a tire supporting rim and an outer diameter surface for contacting a support surface. The torus can flatten under a load to facilitate movement of the tire over soft or irregular support surfaces. A sealable opening permits the inflation and deflation of the torus, and includes a valve stem housing and a valve stem having a plurality of barbs which taper inwardly in the direction of the valve stem housing.
