Air humidity is a vast, sustainable reservoir of energy that, unlike solar and wind, is continuously available. However, previously described technologies for harvesting energy from air humidity are either not continuous or require unique material synthesis or processing, which has stymied scalability and broad deployment. Here, a generic effect for continuous energy harvesting from air humidity is...
This paper presents a compact antenna-sensor interrogator for pressure sensing. A Frequency Modulated Continue Wave (FMCW) generator was developed to detect antenna-sensor's resonant frequency, which encodes the pressure information. The power consumption of this generator is less than 160mW and can be powered by a 3.7V portable lithium battery. In the paper, the operation principle of this FMCW interrogator...
With the rapid development of wind power industry in our country, more and more large scale wind farms are connected to the electricity grid, which makes the grid safety more significant problem, so study the wind generator for the low voltage across (LVRT) technology is very significant. This paper first introduces the present research situation of the LVRT technology and the standards at home and...
In this paper, we first introduce the description of the cyclic code, and according to the features of the cyclic code, build the generator polynomial recognition model in the scenario of coding length known, and then propose an iterative algorithm to reduce the computation complexity; on this basis, through the analysis of the coding frame structure, we build the generator polynomial recognition...
