Abstract: Wear resistance and oxidation resistance of polymer material or a polymer component for bioimplantation are improved by packaging a polymer object in a sealed gas impermeable package substantially free of oxygen, irradiating the package with penetrating radiation to an extent sufficient to effect a desired substantial level of cross-linking within the polymer, and warming the packaged object while maintaining an elevated hydrostatic pressure to cause gases released during irradiation to recombine, stabilizing the material against subsequent oxidative change. The pressure stabilization terminates active sites, substantially eliminating free radicals. When applied to finished parts, the process simultaneously hardens and sterilizes the parts without degrading mechanical properties or dimensions. When applied to bulk material or unfinished parts, the part may be subsequent machined or otherwise finished, and sterilized by any conventional means.

Abstract: This invention involves the use of smart cards configured with data indicating a specific meal plan for use in the food vending industry. Examples of typical applications are student meal plans purchased in college or other school systems where the user purchases a plan allowing the user to eat specific meals or at specific times. Usually the meal plan is purchased at the beginning of the school term and terminates at the end of the school term. The invention uses a memory based smart card that is preconfigured on a specific date. The smart card contains data such as the meal plan type, the expiration date of the plan, the last transaction date, the user's weekly quota of meals, the number of meals a user can eat in a day, the user's daily quota and the operator identification. The smart card is configured by a computer at the start of the meal plan. Smart card readers are used to update data on the smart card and decrement existing data as the user purchases meals.
