20110180059 | SOLAR THERMAL ENERGY SYSTEM - In order to increase the efficiency of a solar thermal system, it is proposed that a measuring robot movable in the longitudinal extension, which can measure the radiance distribution directed at the receiver tube along the receiver and therefore can check if the reflectors of the system are correctly adjusted, be placed on the cover of the receiver, which is supported in a raised manner. | 07-28-2011 |
20130239948 | LINEARLY CONCENTRATING SOLAR COLLECTOR AND METHOD FOR REFLECTOR TRACKING IN SUCH A SOLAR COLLECTOR - The basis for the function of a linearly concentrating solar collector lies, in simple terms, in the fact that reflectors reflect incident sunlight onto a receiver tube through which a heat-absorbing medium flows. Owing to the rotation of the Earth, the reflectors need to be adjusted regularly, however, in order to ensure that the sunlight hits the receiver tube. Known tracking methods use calculated positions of the sun for this purpose, which, in the case of structural deviations, for example as a result of expansion and material stress, results in inaccuracies and losses in efficiency. The invention is intended to improve the tracking of the reflectors in such a linearly concentrating solar collector. This is achieved by virtue of the fact that the radiation intensity in the region on both sides next to the receiver tube is measured and, by means of regulation, in the case of uneven emission on both sides of the receiver tube, the reflectors are tracked to such an extent that the radiation intensity on both sides of the receiver is the same and thus the maximum of the radiation intensity is on the receiver tube. | 09-19-2013 |

A differential transmission technique is selected, wherein one or more conductor pairs (insulated conductors) are utilized, one of the conductors of said conductor pairs transmitting the signal and the other transmitting the inverted signal. By subtracting the two signals, the actual data signal is yielded on the receiver side. If feedback interferences from the environment act on the data transmission link, the subtractions performed on the respective receivers cancels out the interferences. | 09-13-2012 |
