Abstract: Provided are lubricating engine oils including a lubricating oil base stock as a major component and an alkylated aromatic base stock as a minor component. One or more of engine wear and corrosion resistance are improved as compared to engine wear and corrosion resistance achieved using a lubricating oil containing a minor component other than the alkylated aromatic base stock, e.g., an ester having a D5293 viscosity of less than 10,000 cP at ?35° C. In an engine lubricated with the lubricating oil, one or more of engine wear and corrosion resistance are improved as compared to engine wear and corrosion resistance achieved using a lubricating oil containing a minor component other than the alkylated aromatic base stock, e.g., an ester having a D5293 viscosity of less than 10,000 cP at ?35° C. This improvement in engine wear and corrosion control means that engine oils can be formulated with very high saturate content base stocks such as PAOs or GTL stock while providing improved engine durability.

Abstract: A launch control system which maximizes hybrid vehicle acceleration from a standing start. A hybrid vehicle includes wheels, an engine, a motor-generator, a processor, and an actuation device. The processor controls an engine speed and an engine torque independently from a wheel speed and a wheel torque. While the hybrid vehicle is at a standstill, the actuation device is switched to an on state, and the engine speed and engine torque is raised to optimal values. When the actuation device is subsequently switched to an off state, the engine speed and the engine torque is applied to the plurality of wheels to launch the hybrid vehicle. The processor blends or further adjusts the torque applied to the plurality of wheels to maximize the acceleration while optimizing an amount of wheel slip. The processor then learns the launch to improve performance on subsequent launches.

Abstract: A dual rotor, manually steered riding trowel comprises powered, downwardly projecting rotors driven by reduction gear boxes that are tilted by parallel levers beneath the machine. A pair of vertical hand steering levers actuate the parallel levers to tilt the rotors. Each rotor may be swiveled in an arc parallel with the biaxial plane to produce pivoted fore and aft trowel movement. At least one rotor responds to lateral movements of one or both steering levers by tilting in an arc perpendicular to the biaxial plane, moving the trowel left or right. To emulate prior Allen trowels, lateral movements of one of the hand levers is mechanically disabled with a transformation link anchored to the frame. The transformation link may be disconnected from the frame and instead connected to the foot of the companion hand steering lever, allowing both steering levers to pivot laterally, resulting in a different steering “feel.

Abstract: Methods are provided for upgrading the quality of an asphalt containing wax. This can include base asphalts that naturally contain elevated levels of wax, such as base asphalts with a wax content of at least 3.0 wt %. Additionally or alternately, this can include a base asphalt containing subsequently added wax. Wax generated at a refinery can be added to an asphalt along with a pour point depressant to form an asphalt product. The additional wax can reduce the viscosity of the asphalt product at higher temperatures so that the asphalt product can be mixed and stored at a tower temperature. Additionally, the pour point depressant can unexpectedly improve the low temperature properties of the wax-containing asphalt product.

The vertical structure comprises stacked filtering elements and weirs sized to accommodate normal and increased fluid flow for abnormally high surface water flow conditions. The flowing stream containing waste material under normal flow conditions enters the vessel and passes through a filtering wall portion in a lower section of the vertical structure and exits through and effluent pipe. Under higher flow conditions the water flows through an overflow structure mounted on top of a lower cylindrical structure The over flow structure comprises one or more upwardly extending filtering structures and weirs sized to accommodate the excess flow conditions, filter at least a portion of the waste material from said excess flow and direct such excess flow to the effluent pipe.

Abstract: A pedestrian perception alert system configured to issue a warning during real-time when a driver's visual detection of a pedestrian is difficult, and a method thereof is provided. The system includes a video camera, an alert for issuing a warning, a processor, and a Pedestrian Detection Unit (“PDU”). The PDU analyzes the video camera image to detect a pedestrian. A Global Clutter Analysis Unit (“GCAU”) generates a global clutter score. A Local Pedestrian Clutter Analysis Unit (“LPCAU”) generates a local pedestrian clutter score. The processer processes the global clutter score and local pedestrian clutter score so as to generate a pedestrian detection score. The alert is actuated when the pedestrian detection score is outside of a predetermined threshold so as to notify the driver that perception of a pedestrian is difficult at that time.

Abstract: A system for preventing the illumination of a vehicle check engine light by notifying the driver that the fuel door is not closed. The system includes an interference member, a sensor for detecting the position of a fuel door, and a processor to communicate a detectable signal to the driver. The interference member prevents the fuel door from closing if the fuel cap is not properly seated in the fuel injection port, and the sensor detects the position of the door.
