    Abstract: A locomotive consist includes a first locomotive unit that receives a power command from a throttle signal or a dynamic brake signal from MU trainlines, a second locomotive unit with an energy storage system electrically connected to one or more second unit traction motors, and a hybrid control system on the first locomotive unit. The hybrid control system intercepts the throttle signal or the dynamic brake signal from the MU trainlines, calculates first and second alternate power commands for the first and second locomotive units, respectively, that when added together equal the power command received on the MU trainlines, communicates the first power command to the first locomotive prime engine or dynamic braking system, and communicates the second power command to the second locomotive unit.

    Abstract: Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the prevention of thrombosis. The drugs, agents, and/or compounds may also be utilized to treat specific disorders, including vulnerable plaque. Implantable coated medical devices may be processed through annealing to better control the elution characteristics of the therapeutic agents. Furthermore, annealing leads to better therapeutic agent stability and a larger device shelf-life.

    Abstract: A method for predicting and correcting an impending misfire in a homogeneous charge compression ignition (HCCI) engine includes: modeling HCCI engine operation in a nominal, steady-state operating region and in unstable operating regions bordering the steady-state operating region, using a zero-dimensional model; predicting an occurrence of an engine misfire based on the modeling of the HCCI engine operation; and providing a remedial corrective measure when an engine misfire is predicted. The remedial corrective measure includes one of: (a) late injection to avoid full combustion during a trapping cycle, and a reduction in amount of injected fuel to account for residual fuel of the previous cycle; or (b) earlier exhaust valve closing to trigger combustion of residual fuel within the trapping cycle, and a later injection and reduction of injected fuel to account for residual fuel of the previous cycle.
