Abstract: A videophone input apparatus has a communication interface for communicating with a system server, a peer and an A/V output apparatus; a processor; and a memory which causes the videophone apparatus to connect the videophone input apparatus via a local connection to the A/V output apparatus and via a first wireless connection to the system server. The videophone input apparatus transceives configuration information between the videophone input apparatus and the system server via the first wireless connection; establish a peer-to-peer connection between the videophone input apparatus and the peer over a second wireless connection; and trigger a videophone service over the peer-to-peer connection utilizing a service account defined by the system server. Furthermore, the videophone input apparatus provides user input data for the videophone service using the videophone input apparatus; and provide user output data, from the peer, for the videophone service using the A/V output apparatus.

Abstract: A power take-off shaft having constant velocity joints that provide consistent drive shaft speeds regardless of the operating angle of a respective joint and, hence, provide a user with an improved apparatus for transferring mechanical power from a tractor or like machinery to a trailing implement. The constant velocity joints also provide for increased angular displacement between a tractor and trailing implement than commonly used universal joints, are more robust and substantially maintenance free.
