The magnet is fixed to the flexible whisker through a central through hole, and the location of the magnet changes with the swinging of the whisker; the upper and lower circuit boards are identical in shape and size, and are connected through an upright column. A circular hole is formed at the center of the upper circuit board, four Hall sensors are symmetrically distributed on the edge of the circular hole, and the displacement of the whisker in X and Y directions can be obtained by detecting the change in magnetic field generated by the change in location of the magnet; a contact sensor is mounted on the lower circuit board, and is connected to the whisker through a connecting piece, to detect displacement of the whisker in the Z direction.

Abstract: A positioning method using height-constraint-based extended Kalman filter, suitable for a GNSS navigation and positioning system, comprises: obtaining an estimated state value of a current epoch by using an extended Kalman filter algorithm and according to an estimated state value of a previous epoch; constraining a positioning height of the current epoch by establishing a height constraint condition, so as to obtain an optimum estimated value of the current epoch and a corresponding mean square error, wherein the optimum estimated value satisfies the height constraint condition; further correcting the estimated state value by using a pseudorange obtained from the mean square error and a measured. Doppler shift residual to obtain a final estimated state value of the current epoch, thus more accurately obtaining positioning information of a target to be positioned in the current epoch and enhancing the accuracy of GNSS navigation and positioning.

Abstract: The present invention is a method for optimal control of an open space surrounding building form based on sky view evaluation. The method includes the following steps: vectorizing an existing planning scheme, and establishing a 3D model; classifying open spaces in the model, 360°-scanning for mean elevations, calculating and simulating sky views of a whole region, generating a 3D contour plot, and rasterizing the 3D isogram, such that each grid has an open space classification attribute and a sky view value; performing optimal adjustment of the building form on an open space surrounding region having a sky view value that is inconsistent with a corresponding preset sky view index within the range of the whole region, and bringing an adjusted scheme into the model for calculation again, till the sky view value is consistent with the corresponding preset sky view index.

Abstract: A self-reconfigurable returnable mixer includes a self-reconfigurable transconductance stage. The input RF voltage signal is converted into RF current through the self-reconfigurable transconductance stage. The RF current is converted into an IF signal through down-conversion and low-pass filtering. The IF signal is fed back to the reconfigurable transconductance stage; the self-reconfigurable transconductance stage presents an open-loop structure to the input RF voltage signal, and the self-reconfigurable transconductance stage presents the topology structure of the negative feedback amplifier to the fed-back IF signal. The self-reconfigurable transconductance stage circuit achieves a high-linearity IF gain while providing a high bandwidth for the RF signal, effectively alleviating the contradiction between the conversion gain and the IF linearity in the conventional returnable structure.
