A method, apparatus and system is applied to provide a unified content posting mechanism. Pointing objects are detected by a machine view arrangement behind the display surface within a casing of the interactive display. The front end of the external thread is adjoined by a cylindrical spindle section which extends over the entire circumference of the spindle, namely a free-running section, and has an external diameter corresponding to a core diameter of the external thread. Furthermore, the position sensor system includes a control center that is communicably connected to the level sensor and the rotation sensor. The receiving part corrects the time when the job is created based on the difference between the time when the log information is sent, which is indicated by the log send time information added to the log information, and the time when the log information is received based on the protocol using the tagged structured language. The software defined transmit architecture comprises components that can be enabled by associated logic to transmit, for example, communications signals that comply with the global system for mobile communications, enhanced data rates for GSM evolution, which employs TDMA, and wide band code division multiple access transmission standards.
