| 20080197807 | Method of determining the energy capacity of a battery - A method of determining the available energy of a battery provides for measuring first and second open circuit voltage of the battery with a change of energy level occurring therebetween. The two open circuit voltages are correlated to a state of charge level and the measured amount of change of energy is divided by the change of the state of charge. | 08-21-2008 |
| 20090020102 | APPARATUS AND METHOD FOR CONTROLLING MAXIMUM CYLINDER PRESSURE IN AN INTERNAL COMBUSTION ENGINE - An Engine Control Module includes an electronic controller for controlling the position of an EGR valve, the timing of opening and closing of the engine combustion valves, and the timing of the individual cylinder fuel injectors of an engine. Each engine cylinder includes a pressure sensor. Peak cylinder pressure is sent to the ECM during each firing cycle. The ECM is programmed with required maximum percentages of EGR and optimal combustion valve timing for each engine operating condition, and sets the EGR valve and/or the camshaft phaser accordingly to adjust combustion in all the engine cylinders. The ECM also compares the measured peak pressure for each cylinder and adjusts the timing of fuel injection for the next firing cycle to trim the measured peak pressure in each cylinder to a predetermined level at or below the maximum allowable peak firing pressure for the engine. | 01-22-2009 |
| 20090177368 | Method for optimizing fuel injection timing in a compression ignition engine - A method for determining the optimum fuel injection timing angle in a CI engine provided with means disposed in one or more cylinders for measuring Indicated Mean Effective Pressure. The pressure level during the power stroke of a piston is a direct correlate of engine torque being generated, and the timing of fuel injection can increase or decrease the amount of torque. Thus, maximum torque can be obtained by optimizing the timing of fuel injection. An algorithm in the ECM varies the timing of fuel injection in a narrow range until a IMEP maximum is achieved, which timing is then retained and employed until the engine operating conditions change. Thus, the invention can optimize fuel economy by optimizing the torque obtained from each injection of fuel into the cylinders. | 07-09-2009 |
| 20100109437 | Battery pack disconnection method for a hybrid vehicle - A control methodology for an engine-driven electric machine of a hybrid vehicle electrical system for enabling continued operation of the vehicle electrical system under failure mode conditions that require disconnection of the battery pack from the electrical system. At the onset of a failure mode condition requiring disconnection of the battery pack, the electric machine is operated as a generator and controlled in accordance with a first mode of operation such that its output substantially matches the instant electrical load requirements of the vehicle without supplying charging current to the battery pack. When the battery pack current falls below a near-zero threshold, a relay is activated to disconnect the battery pack from the electrical system, and the electric machine is then controlled in accordance with a second mode of operation for maintaining the operating voltage of the electrical system at a specified value. | 05-06-2010 |
| 20100110594 | FAST RESPONSE FAILURE MODE CONTROL METHODOLOGY FOR A HYBRID VEHICLE HAVING AN ELECTRIC MACHINE - A control methodology for an engine-driven electric machine of a hybrid vehicle electrical system for enabling continued operation of the vehicle electrical system under failure mode conditions that require or result in disconnection of the battery pack from the electrical system. At the onset of a fault condition requiring battery disconnection, the electric machine is controlled to drive the battery pack current toward zero before disconnecting the battery pack. Once the battery pack is disconnected, whether by relay or fuse, the electric machine is controlled to maintain the bus voltage of the electrical system at a specified value. In both operating modes, the electric machine is controlled based on a synchronous vector current command that is determined directly as a function of the control objective (zero battery pack current or maintaining bus voltage) for improved response time compared to a traditional torque-based control. | 05-06-2010 |

The enriched compositions are characterized as containing monomeric, oligomeric and polymeric phenols, total phenol concentration >12% and exhibiting in vitro COX-2 inhibitory activity enhanced by a factor of at least 2.5 over a standard aspirin dose of 660 μg/mL. | 08-21-2008 |
| 20080207770 | COMPOSITIONS ENRICHED IN PHENOLIC COMPOUNDS AND METHODS FOR PRODUCING THE SAME - Provided are processes for the preparation of compositions enriched in phenolic compounds from a crude plant extract. One process includes a novel column purification step using a polymer resin that releasably adsorbs the phenolic compounds but does not retain polar non-phenolic compounds, wherein the resin comprises aromatic rings substituted with one or more electron-withdrawing groups. This invention also includes compositions enriched in phenolic compounds. This invention encompasses methods of using the phenolic-enriched compositions for treating warm-blooded animals, including humans, infected with paramyxovaridae such as respiratory syncytial virus, orthomyoxovaridae such as influenza A, B, and C, parainfluenza, Herpes viruses such as HSV-1 and HSV-2, and Flaviviruses such as West Nile Virus, and for treating inflammation such as caused by arthritis, stress and digestive disease. The compositions are also useful as meat additives to inhibit food-borne pathogens. | 08-28-2008 |
