20080250875 | Sparse sampling planner for sensor resource management - A method and system of a sparse sampling planner uses a finite number of measurements to determine a track's expected intermediate kinematic and classification state for a specific sensor action. It uses the expected track state to compute a reward function. The expected states are further propagated for actions at the next time step to determine the next states and so on. The sampling becomes sparse and the reward function is discounted as one propagates further in time. This produces a state-action tree that is more top-heavy while providing greater accuracy at times closer to the decision point. By doing so, the planner creates a plan comprising a sequence of actions that result in the highest reward. By employing various heuristics to further prune the tree gives highly accurate results with significant savings in computational processor time. | 10-16-2008 |

20100058878 | DILUTER FOR EXHAUST GAS SAMPLING AND METHOD THEREFOR - The present invention relates to a device used for the dilution of exhaust gas (diluter) and in particular for engines or vehicles. More particularly, the invention relates to a device and a method which may maintain a constant dilution ratio regardless of the exhaust gas backpressure in the exhaust line, without using any moving parts. The proposed diluter utilizes a very small fraction of the exhaust gas, sampled through a capillary duct, simply immersed to the exhaust flow, which is otherwise freely exhausting to the atmosphere. The sample flowrate through the capillary is achieved by maintaining a regulated underpressure at the capillary outlet. The diluted exhaust is then collected in a stabilization chamber, where temperature, humidity and residence time may be adjusted to condition the collected aerosol at will. Multiple capillaries and stabilization chambers may be cascaded to increase the dilution ratios. After the final dilution stage, particle samples may be collected on a filter for gravimetric determination or analyzed by number counters, surface monitors or any other technique utilized for the physical or chemical characterization of particles. In a preferred embodiment the capillary duct is realized with a hypodermic needle and two cascaded hypodermic needles/stabilization chambers are combined to provide the desired dilution ratio. In another embodiment, exhaust gas may be led to the diluter's capillary duct by means of two probes, located respectively upstream and downstream of any aftertreatment device, which needs to be characterized. By means of shut-off valves, exhaust gas may be fed to the diluter's capillary by either the upstream or the downstream probe, thus providing an estimate of the filtration efficiency of the device. | 03-11-2010 |
