    Abstract: A method and system for providing alternative prepaid service when a serving Packet Data Service Node (PDSN) does not support prepaid or at least the type of prepaid (duration-based or volume-based) the user has subscribed to. The serving PDSN sends an access request to a Home Authorization, Authentication & Accounting Prepaid Server (HAAA/PPS) with an indication of its capability to support prepaid service and to terminate sessions based on requests from remote nodes. When the serving PDSN is neither capable of prepaid service, nor does it support session termination by a remote node, the HAAA/PPS determines that a prepaid session is allowed and supported in combination with a Home Agent (HA) for duration-based prepaid service. When the PDSN is not prepaid capable but supports session termination capability, the HAAA/PPS determines that any type of prepaid service can be allowed and supported by the HAAA/PPS in combination with the HA.

    Abstract: An animal feces collection device includes a tube having distal and proximal end portions defining a path therebetween, a flap coupled to the proximal end portion, a mechanism for pivoting the flap between open and closed positions and a scooping section for collecting animal feces. The pivoting mechanism preferably includes a push button and an elongated arm pivotally connected to the flap and the lower portion of the push button. The scooping section is secured to the proximal end portion of the tube for directing feces rearwardly therethrough when the flap is raised to an open position. The device further includes a reservoir for receiving and storing collected feces and a mechanism for removably attaching the reservoir to the tube.

    Abstract: A method of producing a thermoplastic polyurethane (TPU) compound including a polyurethane powder comprising microcellular polyurethane (MCU). The method minimizes discarding scrap MCU, reduces the cost of TPU articles by introducing a partial replacement for the TPU resin, and reduces injection-molding times to produce TPU articles. The TPU compound including polyurethane powder has superior melt temperature and compression set properties as compared to TPU compounds of similar Shore hardness that are free of the polyurethane powder. The invention also provides a TPU article including the TPU compound and a method of recycling a MCU foam.
