    Abstract: A scaffolding or extendable ladder mechanism is attachable to a rack elevated from a base level. The scaffolding includes a housing fixedly attached to the rack, and a rail mechanism slidably attached to the housing. The rail mechanism is movable between a stowed position and a deployed position. A ladder is movably attached to the rail mechanism, and is slidable and rotatable relative to the rail mechanism. The ladder is movable between a retracted position, substantially within the rail mechanism, and an extended position, substantially outside of the rail mechanism. The extended position of the ladder is also rotated relative to the rail mechanism, and the ladder is nearer the base level in the extended position than in the retracted position.

    Abstract: A vehicle and a window assembly include a window movable between a closed and open position. The assembly includes an arm movable between a first and second position. The window is disposed in the closed position when the arm is in the first position and the window disposed in the open position when the arm is in the second position. The arm includes an extension fixed thereto such that the arm and the extension both move concurrently about a first pivot point. The assembly includes a connector coupled to the extension at a second pivot point. The arm is coupled to the window through the connector. The first and second pivot points are spaced from each other. The connector is coupled to the window such that movement of the arm moves the connector about the second pivot point which causes the window to move between the closed and open positions.

    Abstract: Disclosed are control algorithms and system architectures for managing operation of networked controllers and devices, including vehicles with an onboard network of electronic control units (ECU) and control logic for governing the snoozing and waking of these ECUs. A method for managing a motor vehicle's in-vehicle network of ECUs includes: determining status vectors for a group of the ECUs, each status vector indicating whether the corresponding ECU is awake or asleep; determining device roles for these ECUs—slave or master; determining an assigned hierarchy for selecting the ECUs as the master device; receiving a mode change signal indicating an ECU intends to transition to the asleep state or to the awake state; and, responsively, modifying the respective device role for one ECU from master to slave and the respective device role for another ECU from slave to master based on the assigned hierarchy and the status vectors for the ECUs.

    Abstract: A fastenerless anti-peel adhesive joint includes a first part having a first surface and forming a first anti-peel feature including a first anti-peel surface, a second part having a second surface and forming a second anti-peel feature including a second anti-peel surface, and an adhesive disposed between the first and second surfaces and within the first and second anti-peel features. The adhesive connects the parts via adhesive bonds at the first and second surfaces and at the first and second anti-peel surfaces. The first and second anti-peel features are configured to load the adhesive bonds at the first and second anti-peel surfaces in shear stress when the fastenerless anti-peel adhesive joint is subjected to a peel force that is normal to the first and second surfaces such that the shear strength of the adhesive bonds at the first and second anti-peel surfaces prevents the parts from being peeled apart.

  • Patent number: 10094313
    Abstract: A variety of methods and arrangements are described for controlling transitions between firing fractions during skip fire or other dynamic firing level modulation operation of an engine. In general, actuator first transition strategies are described in which an actuator position (e.g., cam phase, TCC slip, etc.) is changed to, or close to a target position before a corresponding firing fraction change is implemented. When the actuator change associated with a desired firing fraction change is relatively large, the firing fraction change is divided into a series of two or more firing fraction change steps. A number of intermediate target selection schemes are described as well.
