Abstract: A commerce system has a plurality of retailers offering products for sale. Product information associated with the products is collected and stored in a central database. A consumer uses a website to create a shopping list with weighted preferences for product attributes. An individualized discount is generated by a consumer service provider for products on the shopping list directed to the consumer. The shopping list with all products aggregated for one retailer is optimized based on the product information in the database, the weighted preferences for the product attributes, and the individualized discounts. The consumer uses the optimized shopping list to assist with purchasing decisions. An incremental profit can be determined based on an aggregation of the products on the optimized shopping list. Purchasing decisions within the commerce system are controlled by enabling the consumer to select the products for purchase from the retailer.

Abstract: A generating system or transmission system for imparting and transmitting electrical power onto a continuous long electrical conductor for use related to drilling and fluid piping operations. The transmission system may include a power generator/transmitter, voltage transformers, a movable transmission line including the rotational (tubing, piping, casing, liner hanger, drill string, etc.) a receiving circuit/receiver that may be tuned for impedance matching and a converting device to output the transmitted power at a predetermined voltage to be either used immediately by a power consuming device or to be stored in a energy harvesting array such as but not limited to batteries.

Abstract: A sanitary napkin having flaps extending laterally from each of the longitudinal edges of its central absorbent element is provided with fluid retarding means disposed transversely across the absorbent element for inhibiting the transmission of body fluid from a central portion of the absorbent element to the transverse ends. The preferred construction employs the use of two spaced apart compressed channels in the absorbent element. The napkin may include fluid barrier seals between the central absorbent element and the side flaps to prevent the transmission of fluids into the side flap area. The napkin also includes fluid repellant means around the periphery of the transverse ends to aid in preventing end failure.

Abstract: A sanitary napkin having flaps extending laterally from each of the longitudinal edges of its central absorbent element is provided with at least one fluid retarding channel disposed transversely across the absorbent element for inhibiting the transmission of body fluid from a central portion of the absorbent element to at least one transverse end. The preferred construction employs the use of two spaced apart compressed portions of the absorbent element to define a central absorbent portion and delay the transmission of body fluid from the central portion into the transverse end portions of the absorbent element, thereby minimizing the incidence of leakage from the ends of the napkin.
