Method for delaying the development in pest species of resistance to control techniques, using insurance to encourage correct uses of refuges
InactiveUS6338040B1Extended service lifeProtect normal developmentFinanceSpecial data processing applicationsPrimary productionGenetically modified crops
An insurance or warranty method protects financial interests of producers, such as farmers planting transgenic varieties of seed as a primary asset, who use proper refuges of similar but non-transgenic, secondary assets for maintaining a non-resistant pest population. Refuge acre methods, now sometimes called "refugia", as such are recently known in crop pest management, but producers have had no effective incentive and much risk in using them. That is, losses in the refuge from pests, as to corn from European Corn Borers and others, are immediate and could be severe, whereas build-up of resistance to the related control technique is a long-term problem. Providing insurance as part of the cost of the primary production input, or as an add-on "technology fee" or the like, for protecting a set amount of the similar, secondary asset, removes the risks from the pest in producing secondary assets in the refuge. This method helps enforce refuge plan conditions such as size and location of the refuge in relation to that of the primary asset. This insurance or warranty method has broad application in pest control technique management, to genetically modified crops such as corn, soybeans, cotton, and the like and in animal husbandry such as in fish and shellfish farms and disease control in livestock management. It applies to other control techniques such as spraying with insecticides, and to many pests such as European Corn Borer, corn rootworm, corn ear worm, cotton boll weevil, Colorado potato beetle, and the like. When a claim for damage to a secondary asset in a refuge is to be adjusted, the insurance or warranty adjuster may check first for refuge condition compliance (and also can assess development of resistance of the pest species in the primary asset), and will then assess damage from the pest to the secondary asset. The decrease in yield times the crop price is determined and paid to the producer in cash at harvest time, in seed the following season, or in another agreeable fashion in accordance with the insurance policy or warranty terms.

Cantilevered shoe construction
InactiveUS6948262B2Improves ankle stabilityReduce the possibilitySolesNon-surgical orthopedic devicesPush offMusculoskeletal injury
A cantilevered shoe construction for preventing knee and hip osteoarthritis. The shoe construction includes a cantilevered foot support with an anchored lateral side and a fully or partially cantilevered medial side. The cantilevered foot support transfers forces, otherwise transmitted through the medial aspect of the shoe and foot, to the lateral side of the shoe and foot, thereby reducing the knee varus and hip adductor torques to prevent or delay onset of knee and hip osteoarthritis and reducing the ankle joint adductor torque to reduce the risk for ankle sprain injury. The reduction of these joint torques also maintains posture without counterbalancing muscle activity, thereby improving muscle efficiency and performance during weight bearing activities and reducing the tendency for musculoskeletal injury. A spring loading effect of other embodiments enhances the natural coronal foot progression during gait so as to enhance the push off phase of gait.
