  • Publication number: 20130133995
    Abstract: A method is disclosed for forming a brake rotor including a desired custom marking having a predetermined size and shape. The method includes applying a chemical treatment to a marking portion of a surface of the rotor. The marking portion has a size and shape corresponding to the predetermined size and shape of the desired custom marking. The chemical treatment is configured to affect, in a predetermined manner, an ability of a stimulus, to which the rotor is to be exposed, to alter properties of the rotor. The method also includes exposing the rotor, having the chemical treatment applied thereto, to the stimulus. The stimulus alters properties of the rotor at the marking portion differently than the stimulus alters properties of the rotor at other portions of the rotor adjacent the marking portion, thereby forming physical differences in the rotor, which, being visually perceptible, form the custom marking.

  • Publication number: 20130136309
    Abstract: A method of determining functionality of a vision-based imaging system for a vehicle includes capturing images by the vision-based imaging system. The images include landmarks that are identified in multiple images for distinguishing displacement of landmarks between the images. Edge maps for each of the images are generated. Like regions of at least two edge maps are compared for distinguishing displacement of a landmark between the at least two edge maps. Each pixel location of a first edge map is compared with a same pixel location of a second edge map for determining whether each compared pixel location has a different intensity value. An aggregate number of pixel locations having a different intensity value between the at least two edge maps is determined and compared to a threshold. An error message is generated in response to the aggregate number being less than the threshold.

  • Publication number: 20130129489
    Abstract: A feed line for connecting an oil pump to a turbocharger supplies oil to the turbocharger when the oil pump is active. The feed line includes a turbo end and a pump end, which is lower than the turbo end relative to gravity. Oil drains from at least the pump end of the feed line when the oil pump is not active. The feed line has a center axis running therethrough, and a pool zone is disposed between the pump end and the turbo end of the feed line. The center axis of the feed line drops from a main line level on either side of the pool zone to a trap level in the pool zone. The pool zone therefore retains oil when the oil pump is not active.

  • Publication number: 20130131200
    Abstract: A porous polymer separator for use in a lithium ion battery is formed by a temperature-induced phase separation method. The porous polymer separator includes a polymer matrix having opposed major faces and a network of pore openings that extends between the major faces and permits intrusion of a lithium-ion conducting electrolyte solution. As part of the temperature-induced phase separation method, a single phase polymer solution that includes a polymer material dissolved in a miscible mixture of a real polymer solvent and a polymer non-solvent is prepared at an elevated temperature above room temperature. A film is then formed from the single phase polymer solution and cooled to phase-separate the polymer material into a solid polymer precipitate. Additional polymer non-solvent is then used to remove the real polymer solvent from the solid polymer precipitate followed by drying.
