Abstract: A family of transmission gearing arrangements provides a plurality of forward speed ratios and one or more reverse speed ratios by selective engagement of shift elements in various combinations. Three simple planetary gear sets are located on the input axis. One of the simple planetary gear sets may have either a split-ring arrangement in which two ring gears are provided with one carrier and one sun gear, or a split-sun arrangement in which two sun gears are provided with one carrier and one ring gear.

Abstract: A transmission gearing arrangement produces ten forward speed ratios and four reverse speed ratio by selective engagement of three shift elements in various combinations. Some embodiment includes four simple planetary gear sets and seven shift elements of which three or four are brakes. Another embodiment includes two axis transfer gear pairs in place of one of the planetary gear sets. One of the brakes is used only in reverse and may be a latch.

Abstract: A multiple speed power transmission comprises: an epicyclic gearing assembly comprising first, second, third, and fourth rotating members with linearly related speeds; a double pinion planetary gear set with grounded carrier and input driven sun gear; two brakes; four clutches; and specified interconnections. The brakes and clutches are operated in combinations of two to produce eight forward speed ratios and at least one reverse speed ratio.

Abstract: A method of rotating an inventory holder includes moving an inventory holder towards a rotation area along a straight segment of a path with a first face of the inventory holder facing a first direction. The rotation area includes a portion of a workspace designated for rotation of inventory holders. The method further includes moving the inventory holder into the rotation area along a first arced segment with an orientation of the first face perpendicular to the first arced segment. The method additionally includes executing a rotation maneuver within the rotation area and moving the inventory holder out of the rotation area along a second arced segment with a second face facing the first direction.

Abstract: A transmission gearing arrangement includes four simple planetary gear sets, three brakes, and four rotating clutches. The brakes and clutches may be engaged in combinations of three to establish at least ten forward transmission ratios and at least three reverse transmission ratios. The lowest forward transmission ratio and lowest reverse transmission ratio may be used to implement a low range mode, obviating the need for a two speed transfer case.

Abstract: A method for transporting inventory items includes moving a mobile drive unit to a first point within a workspace. The first point is a location of an inventory holder. The method further includes docking the mobile drive unit with the inventory holder and moving the mobile drive unit and the inventory holder to a second point within the workspace. The second point is associated with conveyance equipment. The method further includes moving the inventory holder to a third point within the workspace using the conveyance equipment.

Abstract: A transmission gearing arrangement produces at least nine forward speed ratios and one reverse speed ratio by selective engagement of three shift elements in various combinations. One embodiment includes four simple planetary gear sets, four clutches, and two brakes. Another embodiment includes two axis transfer gear pairs, three simple planetary gear sets, four clutches, and two brakes.

Abstract: A system for transporting inventory items includes an inventory holder and a mobile drive unit. The inventory holder has a frame with device openings. The mobile drive unit is operable to dock with an inventory holder and undock with an inventory holder. When undocked from an inventory holder, the mobile drive unit is further operable to traverse a path from a first location to a second location. The path passes through at least a first device opening of the inventory holder such that the mobile drive unit passes beneath the inventory holder while moving along the path.

Abstract: An infinitely variable power transmission comprising an input shaft, a layshaft driven by the input shaft via internal/external gearing, a toroidal variator, and gearing and clutches which implement a low/reverse variable ratio mode and a high range variable ratio mode. An additional clutch and gearing implement an optional fixed ratio mode.

Abstract: An infinitely variable power transmission comprising an input shaft, a layshaft, a variator transmitting power from the input shaft to the layshaft, an output shaft, and an internal/external gear pair transmitting power from the layshaft to the output shaft. The output shaft axis may be offset a limited distance from the input shaft axis.

Abstract: A system and method for dynamic provisioning of telecommunication connections in a carrier virtual network is provided. Information regarding the layer one resources available for forming a connection is maintained, and may include connection information and latency information. Using connection information and latency information, possible connections complying with service level latency requirements are identified. One of the possible connections may be provisioned. If a linking provisioned connection becomes impaired, another of the possible connections may be provisioned.

Abstract: The present invention provides a system and method for establishing an inverse multiplexed connection using layer one resources dedicated to a carrier virtual network. A plurality of links may be identified that when combined will meet the service level requirements for a connection. The plurality of links may be aggregated at their termination point. The plurality of links may be further aggregated by a carrier virtual network manager. Alternative links may be identified and aggregated if any of the plurality of links become impaired.

Abstract: A device for providing strain relief between an electrical connector and a wiring harness having wires or cables already joined to the contacts of the connector includes a T-shaped plate having axial and transverse members and a pair of opposing, inwardly facing, U-shaped structures disposed at opposite ends of the transverse member and extending at a right angle to the plate from a front edge thereof. The device is mounted on the connector with the U-shaped structures respectively straddling a corresponding mounting flange of the connector and a distal end portion of the axial member extending rearward over a portion of the harness extending rearward from the connector. The two rearward extending portions of the plate and harness are cinched together with a strap or the like. The device can be installed after the harness has been assembled without the need to remove the wires or contacts from the connector.
