  • Patent number: 9689481
    Abstract: A one mode, front wheel drive continuously variable transmission includes a transmission input member interconnected to an engine of the motor vehicle, a transmission output member, a continuously variable unit having a first pulley pair, a second pulley pair, and a chain wrapped around the first pulley pair and the second pulley pair. A planetary gear set includes a first member, a second member, and a third member. The first member is connected to the first pulley pair and the third member is connected to the transmission input member. A clutch is selectively engageable to connect the first member of the planetary gear set with the transmission input member.

  • Publication number: 20170175866
    Abstract: A damper system includes a turbine shaft rotatably connected to a torque converter having a clutch. A hydraulically actuated clutch is coupled to the turbine shaft. A first spring cage has a first cage portion connected to the hydraulically actuated clutch and a second cage portion connected to a friction plate. A first spring set is connected to the first and second cage portions. Springs of the first spring set are deflected by axial rotation between the first and second cage portions when the torque converter clutch is engaged. A second spring cage has a first cage section connected to the hydraulically actuated clutch and a second cage section connected to a torque converter turbine. A second spring set has second springs having a spring constant different than the first spring set. The second spring set springs are deflected by axial rotation between the first and second cage sections.

  • Publication number: 20170147095
    Abstract: A user of a computing device may view an initial content item in a landscape orientation on a display of a computing device. When the user rotates the computing device, supplemental content may be presented in a portrait orientation on the display of the computing device. The supplemental content may include virtually any information in which the user may be interested and/or that is related or similar to the content item. Accordingly, rather than presenting such supplemental content upon an affirmative request or search by the user, the supplemental content is presented to the user automatically when the user rotates the computing device from a landscape position to a portrait position or vice versa.

  • Publication number: 20170138450
    Abstract: A continuously variable transmission (CVT) for a motor vehicle includes a transmission input shaft rotatably connected to an engine by a torque converter, the transmission input shaft defining a first CVT axis. A continuously variable unit connected for rotation by the transmission input shaft includes a first pulley assembly, a second pulley assembly, and a flexible member wrapped around the first pulley assembly and the second pulley assembly. A two mode transfer gear assembly is connected to the second pulley assembly and is coaxially aligned for rotation on a second CVT axis. A clutch assembly having at least one clutch is connected to the transfer gear assembly. A final drive unit connected to the transfer gear assembly is co-axially aligned with respect to the second CVT axis.

  • Patent number: 9576109
    Abstract: Revenue generated through electronic book sales (and other transactions, such as rental, sample, leasing, etc.) is allocated among rights holders and other parties based on a ranking of common work distributed in electronic book form or any other form (e.g., paperback, hardcover, audio). As the ranking changes, the revenue allocated to the rights holder changes. The changes may be made in real-time as revenue and metric data is collected.
