  • Patent number: 9330357
    Abstract: Provided herein are systems, methods and computer readable media for classifying a provider of products, services or experiences as a provider that should be engaged based on a predicted return rate for any products, services or experiences that may be offered and purchased by a consumer. An example method may comprise supplying a classifying model with a dataset, wherein the dataset comprises an identification of a provider and a plurality of attributes corresponding to the provider and identifying a class of the provider in accordance with the plurality of corresponding attributes, wherein the identification is determined based on one or more patterns determinative of a return rate by the classifying model.

  • Publication number: 20150379545
    Abstract: Embodiments of the present invention provide systems, methods and computer readable media for calculating the capacity of a provider by calculating, using biographical data representing the provider, a first total units of service that are available to be offered to consumers during a first time period; calculating a second total units of service potentially available from the provider for a proposed second time period using a projection based in part on a model of consumer demand for the units of service; determining a third total units of service that are unavailable during the second time period based on at least one known or projected unavailability; and calculating a capacity based on the third total units of service and the second total units of service, the capacity being a capacity for a proposed promotion representing a maximum total of instruments to be offered in the proposed promotion by the provider.

  • Patent number: 6039972
    Abstract: A conformable wound dressing is prepared by producing a sub-confluent layer of cultured mammalian cells such as epithelial cells anchored to a surface of a synthetic polymeric film which is hydrophobic, non-inhibitory to cell growth and non-cytotoxic. The polymer may be ethylene-vinyl acetate copolymer or a blend of ethylene-vinyl acetate copolymer and polystyrene, and is preferably subjected to corona discharge to improve cell attachment. The polymeric film may be sterilized with ethylene oxide or by gamma-irradiation. Preferably, the polymeric film is a continuous film containing apertures formed by perforation before or after cell culture to provide an apertured wound dressing. In a preferred embodiment, a laminate is formed containing a sub-confluent layer of mammalian cells anchored to a surface of a continuous film of synthetic polymer having a plurality of thin and thick portions cast on and supported by a carrier layer having a plurality of raised portions.
