Abstract: A tailgate counterbalancing hinge assembly includes a linear torque rod, a first end assembly and a second end assembly secured to the torque rod. A first end assembly pivotally supports the tailgate while permitting a torque rod end to be rigidly coupled to the tailgate for movement with the tailgate about a pivot axis. A second end assembly also pivotally supports the tailgate and permits the other end of the torque rod to be rigidly connected to the vehicle body. The first end assembly includes a bushing and split pivot body rotatably mounted within the bushing that creates increasing friction between the split pivot body and the bushing as the torque rod is twisted due to the tailgate being opened. The increasing friction creates a progressively increasing braking or dampening effect, which slows the free fall of the tailgate as it is opened.

Abstract: An object of the invention is to prevent original high quality contents data from being illegally obtained by extracting encryption breaking information from data transmitted through a single signal line for connecting two apparatuses and by using the encryption breaking information to decrypt encrypted contents data. In a contents data transmission/reception system, a contents data transmitter encrypts contents data by using key information, transmits the key information through plural signal lines to a contents data receiver, and then, transmits the encrypted contents data through the plural signal lines to the contents data receiver. The contents data receiver acquires the key information from data transmitted from the contents data transmitter through the plural signal lines, receives the encrypted contents data transmitted from the contents data transmitter through the plural signal lines, and decrypts the encrypted contents data by using the key information.
