20130342336 | ALERT SYSTEMS AND METHODS FOR A VEHICLE - A method of alerting a driver of a vehicle is provided. The method includes: receiving conditions data from one or more collision avoidance systems; determining an alert mode based on the conditions data; receiving a fault status indicating a fault of at least one of a haptic alert device, a visual alert device, and an auditory alert device; resetting the alert mode to an override mode based on the fault status; and selectively generating an alert pattern for at least one of a haptic alert device, a visual alert device, and an auditory alert device that does not have a fault based on the override mode of the alert mode. | 12-26-2013 |
20100186422 | Efficient and light weight thermoelectric waste heat recovery system - One embodiment includes an on-board thermoelectric vehicle system for generating electrical energy using a heated fluid stream, including at least one thermoelectric device having a high temperature junction and a low temperature junction, and a body of high conductivity foam shaped and located to increase heat transfer from the heated fluid stream to the high temperature junction or to increase heat transfer from the low temperature junction of the thermoelectric device. | 07-29-2010 |
20100077742 | FLOW DIFFUSER FOR AN EXHAUST SYSTEM - Exemplary embodiments of the present invention provide devices, systems and methods for distribution of an engine exhaust gas to one or more exhaust treatment devices. In one embodiment, an exhaust flow diffuser is provided including a conduit defining an inlet opening, an outlet opening and a flow path therebetween. The conduit includes a first section disposed proximate to the inlet opening and a second section disposed proximate to the outlet opening. The second section has an increasing diameter along its length. The conduit is formed by a first member and a second member both of which extend between the inlet opening and outlet opening to form a portion of the first section and the second section. The first member and the second member each include an engagement feature that extends between the inlet opening and outlet opening. | 04-01-2010 |
20100038353 | TRANSVERSE OVEN AND METHOD OF BAKING WORKPIECES - A manufacturing oven for and a method of baking a workpiece presenting a transverse orientation relative to the oven, includes dual radiant and convection heating sources operable to uniformly heat the workpiece by focusing convection heating air towards desirous parts of the workpiece, and preferably includes a chamber, a high emissivity false floor, at least one radiant heating element beneath the floor, at least one reflector beneath each element and configured to redirect radiant heat energy towards the floor, a fresh air heater for delivering fresh heated air into the chamber, an exhaust system for removing heated air and evaporated paint solvents from the chamber, and at least one ceiling fan operable to cause lighter heated air to flow from the ceiling of the chamber and towards the workpiece. | 02-18-2010 |
20080228380 | Internal Combustion Engine for Operation with Two Different Knock Resistant Fuels - The invention relates to an internal combustion engine which can be operated with at least two fuels that have different knock resistance and which comprises at least one cylinder in which combustion of the fuel takes place cyclically. Said engine is provided with a dosing system for feeding a controlled quantity of fuel to the cylinder in every cycle. The dosing system is designed in such a manner that, when fuels are used that are less resistant to knocking, the quantity of air-fuel mixture supplied is maintained below a threshold quantity at which there is no danger of knocking. | 09-18-2008 |
