  • Patent number: 7467091
    Abstract: A business method and system that effectuates collaboration on Customer Pick-UP (CPU) between one or many buyers (customers) and sellers (suppliers) in a supply community. The method and system have particular utility in markets where the standard terms of sale are Destination Delivered. The method and system enables sellers to create, configure and maintain seller-specific CPU programs having at least one strategy option and at least one CPU allowance unit rate structure option which can be contemporaneously accessed by buyers to identify potential CPU opportunities and then submit a CPU proposal/request, each based on a single CPU strategy option, to one or more sellers, wherein the CPU proposal/request is a collaboration invitation, a supply bid or a request for a lane allowance quotation structured to facilitate structured to facilitate the agreement of a mutually acceptable CPU allowance unit rate consistent with the selected CPU strategy option.

  • Patent number: 7385500
    Abstract: A method and system for effectuating the optimum configuration of a duplex tracking device used to track the location and attributes of a mobile asset during a discrete event and the distribution of the data reported by the device so that the owner of the mobile asset and one or more of the owner's business partners can contemporaneously access the tracking data that they require. Each party first specifies a minimum configuration for all events with which they are associated, and then optionally specifies more extensive configurations for classes of discrete events. The owner may also constrain the data that partners can request by specifying access authorities for each class of business partners. The configuration parameters for a discrete event are systematically determined to minimize the data to be reported by the device while still meeting the requirements of all the parties, as constrained by the access authorities.
