Abstract: Aspects include a robotic device for inspection of components of a belt conveyor comprising a mobile platform and a robotic arm having a first end coupled to the mobile platform and a second end, the robotic arm configured to guide the second end to contact at least one of the components of the belt conveyor. Further included is a method for inspecting components of a belt conveyor using a robotic device, including: obtaining temperature and/or noise data of at least one of the components of the belt conveyor; and, if the data are outside a range, then: driving a second end a robotic arm of the robotic device for contacting at least one of the components; and obtaining vibration data from at least one of the components.

Abstract: The invention relates to a baseband predistortion system for the adaptive linearization of power amplifiers and to a radiotransmitter using the predistortion system. It is based upon the updating of two error tables, one for the amplitude and one for the phase, whose content is used for correcting the baseband samples. The content of the tables is obtained by accumulating the difference, suitably weighed, between the sampling entering the predistortion device and the demodulated feedback value.
