    摘要： A dual clutch transmission for a motor vehicle power train for selectively coupling rotating transmission members includes a base assembly, a bearing mounted rotating assembly which is rotatable with respect to the base assembly, first and second torque transmission assemblies movable between disengaged and engaged positions, and first and second actuation mechanisms associated with the first and second torque transmissions assemblies. The actuating mechanisms are arranged for moving the respective torque transmission assemblies between the disengaged and engaged positions for selectively coupling the transmission members. The first torque transmission assembly couples two rotating members in the engaged position. The first actuating mechanism includes a hydraulic actuating mechanism having a piston chamber and a piston for moving the first torque transmission assembly between the disengaged and engaged positions. The piston chamber is arranged in the base assembly, and the piston actuates the first torque transmission assembly in the rotating assembly.

    摘要： A clutch assembly includes a first shaft extending along and rotatable about a first shaft axis, and a second shaft extending along and rotatable about a second shaft axis that is parallel with the first shaft axis. The clutch assembly also includes a first friction component coupled to and rotatable with the first shaft, and a second friction component coupled to and rotatable with the second shaft. The clutch assembly additionally includes a band clutch assembly. The band clutch assembly includes a retaining band disposed about the first and second friction components, and a retaining component coupled to the retaining band. The retaining band is engageable with the first and second friction components, and the retaining band and the retaining component are rotatable with the first and second shafts during rotation of the first and second shafts.

    摘要： A kit for modifying an OE vehicle transmission includes a replacement forward piston housing, forward clutch hub and a forward clutch and a replacement direct piston housing, direct clutch hub and a direct clutch. A drum extends between and operably connects the replacement forward piston housing and direct piston housing. The kit includes a replacement sprag shaft. The forward clutch hub and forward clutch and the direct clutch hub and direct clutch are positioned between the forward piston housing and the direct piston housing. At least a portion of the forward clutch and at least a portion of the direct clutch are operably mounted to the drum. The forward piston housing and direct piston housing do not counter rotate relative to one another. A power flow module for an OE vehicle automatic transmission is disclosed.

    摘要： Among other things, this document describes systems, devices, and methods for improving the delivery and performance of web pages authored to produce virtual reality (VR) or augmented reality (AR) experiences. In some embodiments, such web pages are analyzed. This analysis may be initiated at the request of a content server that receives a client request for the HTML. The analysis may involve, asynchronous to the client request, loading the page into a non-user-facing browser environment and allowing the VR or AR scene to execute, even including executing animation routines for a predetermined period of time. Certain characteristics of the scene and of objects are thereby captured. Based on this information, an object list ordered by loading priority is prepared. Consulting this information in response to subsequent requests for the page, a content server can implement server push, early hints and/or other delivery enhancements.
