Abstract: A system, method, process, and mechanism for fulfilling multi-vendor orders within a drive-through complex with a vertical transport system that delivers the multi-vendor orders to pick-up stations located below the floors with the vendors. The system receives an order from a user device of a user, wherein the order includes at least two sub-orders. The sub-orders are processed based at least on the preparation times. The sub-orders are tracked and an available drive-through lane with an available pick-up station is determined for the order including the sub-orders. Notifications may be sent to a user or third party user for order pick-up. When the order is complete, it is consolidated and the order is transferred to the available pick-up station.

Abstract: Molded elastomeric polyurethane foams suitable for use as gasketing and sealing devices for use in hot environments are disclosed. The foams are the reaction product of an aromatic polyisocyanate with an isocyanate-reactive composition that includes one or more polyether polyols, certain diol chain extenders, and certain low equivalent weight hydroxyl-containing cross-linkers. The molded foams exhibit low compression sets after being compressed and aged at elevated temperatures.

Abstract: A polyurethane elastomer showing desirable conductivity properties comprises at least 0.3 percent by weight of an aggregated particulate carbon black, having a particle size of less than or equal to 100 nanometers, that forms a continuous conductive pathway within the polyurethane elastomer. The polyurethane elastomer may exhibit a surface resistivity ranging from 1×104 to 1×108 ohms. It may be made by first preparing an isocyanate-terminated prepolymer containing the carbon black, the prepolymer having a volume resistivity of from 1×104 to 1×108 ohms, and then reacting the isocyanate-terminated prepolymer with an isocyanate-reactive component. The proportion of the prepolymer ensures that it forms a continuous phase in the final elastomer.

Abstract: A network device which is for use in an Ethernet packet-based communication system has at least one port which is capable of auto-negotiation to select between half duplex and full duplex working on a link to which the port is connected. The device includes means for monitoring the existence of late collisions between packets on said link, means for monitoring the existence of packet fragments on the link, and monitoring means for detecting and correcting for a duplex mismatch on the link partner. This monitoring means is operative to determine whether there are any late collisions and in the absence of a detection of fragments to configure the port from a half duplex mode to a full duplex mode. The monitoring means is also operative to detect the presence of fragments when the port is in full duplex mode and thereby to provide an indication that a rule relating to network size is infringed.
