Abstract: A heavy duty truck includes a diesel engine that generates an exhaust gas flow and an exhaust after-treatment system for treatment of the exhaust gas flow. The exhaust after-treatment system includes at least one heater and at least one selective catalytic reduction system downstream of the heater. The heater is operated to inject supplemental heat energy into the exhaust gas flow at a rate based on a difference between a target rate of heat energy in the exhaust gas flow at an inlet to the selective catalytic reduction system and a rate of heat energy supplied to the exhaust gas flow from the diesel engine.

Abstract: Systems and methods for predictive adaptive cruise control of a plurality of vehicles traveling in succession. A system engages in a vehicle-to-vehicle communication session with one or more vehicles of the plurality of vehicles. During the communication session, terrain information is obtained and first speed trajectory information is determined for an upcoming segment of road. Second speed trajectory information is received from a first adjacent vehicle of the plurality of vehicles. Third speed trajectory information is generated based on the second speed trajectory information received and the terrain information. The operation of the vehicle is controlled during the upcoming segment according to the third speed trajectory information.

Abstract: Card shuffler apparatuses include a card repositioner used to randomly reposition a plurality of cards on-edge over an aperture extending through a card support surface to allow cards to sequentially pass through the aperture in a random order. The apparatuses may be capable of continuously and sequentially forming playing card hands for use in a game. Shuffler apparatuses may be used to obtain a measurement relating to a thickness of the deck of cards. Methods involve the use of card shuffler apparatuses to form one or more playing card hands in a playing card game. Additional methods involve counting playing cards present within a stack of playing cards using a shuffler apparatus. In further methods, a number of shuffler apparatuses and a lesser number of shuffler activation devices are provided in a gaming establishment so as to preclude simultaneous use of all the shuffler apparatuses in the establishment.

Abstract: A module that calculates power loss for an internal combustion engine includes an air intake calculation module that determines a final air per cylinder (APC) value. A fuel mass rate calculation module that determines a fuel mass rate value based on the final APC value. A power loss calculation module that determines a power loss value for the internal combustion engine based on the fuel mass rate value.

Abstract: A control system for an internal combustion engine includes a virtual engine model which mathematically represents the states of the engine in real time, but which is programmed to provide the engine's states at least a fraction of an engine cycle (and preferably at least one-fourth of an engine cycle, i.e., one stroke) to several engine cycles in advance of the real engine. The mass flow entering and leaving the cylinder is modeled, allowing parameters such as the mass of air per cylinder (MAC) and residual exhaust gas to be computed, and thereafter used to generate engine control commands related to fuel injection (air/fuel ratio), spark advance, and so forth.

Abstract: A testing device allows a test engine (such as a single-cylinder test engine) to experience the air exchange characteristics of a multi-cylinder test engine having a greater number of cylinders. The test engine receives air from an air source (such as the atmosphere) through the interior passage of an air intake adapter, wherein valves on the passage walls separate the interior passage from a negative or positive pressure source. A processor (such as a computer) may actuate the valves to allow air to be pulled from the passage to simulate the effect of air intake into additional virtual cylinders (i.e., cylinders that would operate in tandem with the cylinder(s) of the test engine if the test engine had a greater number of cylinders), and/or to simulate the effect of forced air induction (i.e., turbocharging or supercharging).
