  • Publication number: 20120255279
    Abstract: A system and method for providing energy to auto systems such as systems after-treating exhaust. Energy may be received from a solar energy source electrically connected to an after-treatment system. At least some of the energy from the solar energy source may be provided to the after-treatment system to purify exhaust from an engine. A control module may provide at least some of the energy from the solar energy source to a heater, for example, to initiate heating the after-treatment system prior to starting the engine. The heater may heat the after-treatment to temperatures within a predetermined temperature range associated with optimal efficiency for the after-treatment system.

  • Publication number: 20120247084
    Abstract: An internal combustion engine vehicle or hybrid-electric vehicle is provided with a vehicle-mounted solar cell array capable of generating electrical power. The solar cell array and other elements, including a metal substrate catalytic convertor form a system for reducing exhaust gas emissions from the vehicle in which the power from the array is applied to minimize exhaust emissions. A primary application of the solar cell array-generated power is to preheat the catalytic convertor to a preferred operating temperature prior to engine start. But the power from the solar cells, directed by a controller, may also be applied to charge the battery or to power electric power receiving devices, for example, to control cabin temperatures. The preferred allocation of the solar power available depends on a number of factors including the state of charge of the batteries, and the time of anticipated next use of the vehicle.

  • Publication number: 20120063838
    Abstract: A docking mechanism attachable to a first table capable of docking the first table with a second table through at least one locking feature associated with the second table is disclosed herein. The mechanism comprises: a tapering receiving chamber having a locking groove for receiving the locking feature from the second table and a lock lever located adjacent to the locking groove, the lock lever being moved to dock the tables. A link lever is attached to a lock lever, the link lever being rotated through the lock lever to dock the locking feature with the locking groove. A gearing assembly is provided in association with the receiving chamber having a first gearing unit linked with a second gearing unit, the first gearing unit being connected to the link lever. The link lever rotates without rotating the first gearing unit while docking the tables and the lock lever rotates through the first and second gearing unit to undock the patient tables.

  • Publication number: 20110301790
    Abstract: An electric or hybrid-electric vehicle is provided with vehicle-mounted solar cells capable of generating electrical power. The power from the array is directed to vehicle systems according to a pre-determined algorithm intended to most effectively extend the vehicle range when operated under electric power. Power from the solar cells is directed by a controller, and may be applied to directly charge the batteries or to power electric power receiving devices, for example, to control cabin temperatures, depending on factors including the state of charge of the batteries, whether or not, the vehicle is parked and the current cabin temperature. The controller is also capable of controlling and managing the operating voltage of the solar cells to ensure optimal power extraction from the cells.

  • Publication number: 20070209073
    Abstract: Described is a technology including an evaluation methodology by which a set of privileged code such as a platform's API method may be marked as being security critical and/or safe for being called by untrusted code. The set of code is evaluated to determine whether the code is security critical code, and if so, it is identified as security critical. Such code is further evaluated to determine whether the code is safe with respect to being called by untrusted code, and if so, is marked as safe. To determine whether the code is safe, a determination is made as to whether the first set of code leaks criticality, including by evaluating one or more code paths corresponding to one or more callers of the first set of code, and by evaluating one or more code paths corresponding to one or more callees of the first set of code.
