Abstract: 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.

Abstract: A method for sharing a configuration file is applicable to a first host and a second host that are connected to a network, wherein the first host is electrically connected to the first peripheral device, and the second host is electrically connected to the second peripheral device. The method for sharing a configuration file includes: the first host starts the embedded program, and after obtaining the first public key of the first peripheral device, the embedded program is communicatively connected to a server, and the device requests a private key according to the first public key. After obtaining the private key, the embedded program uploads a configuration file, and the second host starts the embedded program.

Abstract: A magnetic reader head assembly includes a magnetic reader head compartment, a frame and an elastic component. The magnetic reader head compartment comprises electronic and mechanical components of the magnetic reader head. The frame has a front side and a back side and has a footprint matching the footprint of the magnetic reader head compartment. The front side is configured to attach to a back wall of the magnetic reader head compartment while allowing the magnetic reader head compartment to move out or retract from the frame. The elastic component is configured to be placed at the back side of the frame and to push the frame out in order to press the magnetic reader head compartment against a magnetic card stripe.
