Abstract: An apparatus in one example may have a functionality of a policy decision function divided into two parts; one part representing a home network application function and the other part representing visited network bearer resources and local policies. The one part of the policy decision function supports communications with the application function, and represents the home network and application in a request for QoS control to the visited network. The other part of the policy decision function supports visited network interactions with a policy enforcement function, and represents visited network local policy related to resource utilization and roaming agreement-based policy.

Abstract: An apparatus in one example may have: at least two endpoints operatively coupled to one another via an application function (AF) in a home network; a policy decision function operatively coupled to the AF; a policy decision enforcement (PDE) operatively coupled to the one of the endpoints; the PDF operatively coupled to the PDE; and a QoS managed bearer that is operatively connected to the endpoints.

Abstract: An apparatus in one example may have: at least two endpoints operatively coupled to one another via an application function (AF) in a home network; a combined policy decision function (AAA-PDF) operatively coupled to the AF; a combined policy decision enforcement (PDE) operatively coupled to the one of the endpoints; the AAA-PDF operatively coupled to the PDE; and a QoS managed bearer that is operatively connected to the endpoints.

Abstract: A drive assembly for a bilaterally symmetrical machine such as a vehicle or aircraft is provided to precisely control and vary engine power delivered to a pair of opposed drive mechanisms of the assembly. Each drive mechanism includes a first differential clutch connected with a power source via a power splitter, a drive element such as a wheel or propeller connected with the first differential clutch, and a first braking device connected with the first differential clutch to independently control the delivery of power to the drive element. A second differential clutch may be provided for each drive mechanism to control movement of the drive mechanism in an opposite direction.

Abstract: The present invention relates to the removal of hydrocarbon residues from a catalyst and more specifically the air activation of a catalyst containing hydrocarbon residues. It also relates to extruded pipe and utility conduit resins comprising polyethylene, household/industrial chemicals container resins, and to a polyethylene resin particularly suitable for large parts by blow molding and sheet extrusion procedures, wherein the resin is made by a process using an activated chromium and titanium-based catalyst.

Abstract: A heat energy recovery system for cooling an internal combustion engine is characterized by separate oil and water circuits. The oil circuit is used to lubricate and cool the engine. A heat exchanger between the oil and water circuits cools the oil and produces steam from the water. The steam is used to power a steam engine in the water circuit which in turn is used to drive accessories normally driven by the engine. The recovery of heat from the cooling oil and the generation of energy via the steam engine reduces the load on the engine, decreasing its fuel consumption and increasing its net output to drive a vehicle.

Abstract: A turbocharged engine air supply system for eliminating turbo lag in an internal combustion engine includes an air tank containing a pressurized auxiliary air supply which is used to raise manifold pressure promptly during periods of turbo lag, an air pump connected with the engine crankshaft for filling the air tank with compressed air during deceleration and during other periods of operation when it is not necessary to devote all of the engine torque to the driveline, a first valve for controlling the flow of auxiliary air from the air tank to the engine, and a second valve for recirculating turbocharged air when auxiliary air is being supplied to the engine, thereby allowing the turbocharger to accelerate more quickly.
