    Abstract: A torque transfer apparatus for a transmission includes a rotatable friction clutch pack including a first friction plate that is contiguous to a second friction plate, with the first friction plate coupled to a first transmission element and the second friction plate coupled to a second transmission element. A Belleville spring device is configured to urge the first friction plate to engage the second friction plate to effect torque transfer therebetween when a hydraulically-activated piston is deactivated. The hydraulically-activated piston is configured to urge the second periphery of the Belleville spring device away from mechanical contact of the first friction plate when the hydraulically-activated piston is activated.

  • Publication number: 20120145113
    Abstract: Methods for removal of condensed, blow-by contaminants with small molecular dimensions from the circulating lubricating engine oil of internal combustion engines, including automotive engines, with a positive crankcase ventilation system are disclosed. An adsorbent macroporous structure comprising alumino-silicate particles with micro-pores is at least partially immersed in the circulating oil. The micro-pores are sized to adsorb the small, condensed, blow-by, contaminant molecules but not the larger oil molecules. At low temperatures the contaminant molecules may be adsorbed and temporarily stored in the micropores. At higher temperatures some of the contaminants may desorb and be re-incorporated in the oil. The desorbed contaminants will circulate with the higher temperature oil into the engine crankcase where they may vaporize and be removed by the engine positive crankcase ventilation system.

  • Publication number: 20120136532
    Abstract: A system and method is provided to index the door window glass of a vehicle to disengage the glass from the window sealing interface prior to opening the door. A door latch including an unlatching lever selectively connectable to the inside and outside door handles is configured such that moving either handle to actuate the latch causes an initial change in the position of the unlatching lever prior to latch release. A sensor in the latch detects the initial change in position of the unlatching lever and signals an indexing mechanism to move the glass to the indexed position prior to latch release, such that the glass does not substantially interfere with the sealing interface when the door is moved from a closed position. The system may be configured such that the door lock mechanism must be unlocked prior to the indexing mechanism moving the window to an indexed position.

  • Publication number: 20120135747
    Abstract: A system and method for entering a destination into a navigation system, usually a vehicle navigation system, that reduces the cognitive load on the vehicle user over known systems. The method includes contacting the destination by any suitable and available manner, such as by a cell phone provided on or in the vehicle, through the internet, through an ad-hoc network, etc., where information concerning the GPS location of the destination is sent back to the navigation system and is displayed on the navigation system screen. If the destination is accurate, the vehicle driver can select that destination, such as by touching an icon on the screen, which would allow the destination entry process to be performed while the vehicle was moving.
