Abstract: Provided is a cylinder connection assembly comprising a ventilation connection sleeve sleeved on a piston shaft of the cylinder, the ventilation connection sleeve fixedly provided in a cylinder barrel of the cylinder and separates an inner cavity of the cylinder barrel to form front and rear air chambers, a first ventilation hole communicating with the front air chamber and a second ventilation hole communicating with the rear air chamber are provided on the ventilation connection sleeve, so that when the compressed gas is filled into the front air chamber through the first ventilation hole, or the compressed gas is filled into the rear air chamber through the second ventilation hole, the piston assembly in the cylinder barrel can move axially. Through the ventilation connection sleeve provided in the cylinder barrel, the compressed gas can directly enter the front air chamber or the rear air chamber through the ventilation hole thereon.

Abstract: A closure element of a motor vehicle, the closure element having a closure body, to the exterior of which a decorative strip is connected. The decorative strip accommodates a radar sensor unit having a housing.

Abstract: A screw forwarding device for a screw feeder includes a base plate, a vibration mechanism including at least one spring and a vibration motor connected to the at least one spring, and a rail for receiving screws. The rail is connected to a first end of the at least one spring and the at least one spring is arranged at an oblique angle to the rail. The screw forwarding device further includes a fastening mechanism for rigidly connecting a second end of the at least one spring to the base plate, whereby a movement path of the vibration mechanism, during a use of the screw forwarding device, defines a plane of movement. The base plate is oriented substantially parallel to the plane of movement defined by the vibration mechanism.

Abstract: A system and methods to generate and deliver concentric-user targeted content is provided. The concentric user-targeted content delivery system cooperates with a user profile data store and users' usage behavior data store to generate a baseline of users' preferences. Using the preference information a range of relevant content, obtained from a cooperating content data store, is matched for a particular user using at least one matching algorithm. The range of relevant content reflects a comprehensive description of a user's preference in totem. In operation, user profile information along with a user's usage behavior information is processed to generated a user's preference information. The preference information is processed to aggregate a range of relevant content from a cooperating data store. In an illustrative implementation, the range comprises micro, mezzo, and macro-related content that are related in various degrees to the user's profile and/or usage behavior information.
