| 20120197500 | SYSTEM AND METHOD OF SPEED-BASED DOWNSPEED COASTING MANAGEMENT - A velocity profile can be used in conjunction with vehicle operating condition data to determine a gear shift schedule that mitigates the amount of service brake effort required to slow a vehicle by making optimal use of engine speed, friction and engine brakes. The gear shift point drives the engine to a higher operating speed and greater frictional torque, slowing the vehicle, which can then coast to a desired speed. The gear shift point can be timed to minimize fuel consumption during the maneuver. Thus, a vehicle downshift event is created based on the transmission gear recommendation.

Additionally, most routes have an abundance of vehicle fueling stations that provide ample refueling opportunities, thus permitting an operator to carry less fuel than might be required to complete a route. Exemplary embodiments of the present disclosure balance initial fuel loading and fuel stops to optimize the amount of freight weight that can be carried for a given route.

| 20100040747 | SILICA MICROGELS FOR REDUCING CHILL HAZE - The present invention provides a method of reducing chill haze in a protein containing liquid (especially beverages resulting from fermentation such as beer and wine) by contacting the liquid with silica microgels having an average microgel diameter of at least 18 nm, more preferably at least 45 nm, and most preferably at least 70 nm. It has now been discovered that microgels having an average microgel diameter of less than about 18 nm do not adequately reduce chill haze of a protein containing liquid. In particular, while microgels having an average microgel diameter of less than about 18 nm cause the coagulation of haze-forming components, these components remain suspended in liquid and continue to cause haze despite allowing the liquid to settle for long periods of time. Conversely, it has now been discovered that microgels having an average microgel diameter of at least about 18 nm cause the coagulation and precipitation of haze-forming components and the rapid settling thereof without the use of an organic polymer which acts as a flocculating agent. | 02-18-2010 |
