Abstract: An isolated cell membrane potential detection system can measure a cell membrane current change when light having different parameters such as wavelength, energy density, pulse width, and repetition rate stimulates a cell to be detected, to detect whether the biological electrical activity of the cell can be regulated by light, and to detect the specificity of the light regulation parameters of the cell. In the light regulation cell membrane potential detection system, a method of progressively adjusting and detecting with multiple optical parameters from small to large is used to measure a cell membrane current change in different periods under a certain photostimulation parameter for each group of cells, so as to quickly and efficiently detect which type of optical signal can regulate the characteristics of the cell such as the generation of a membrane current, photostimulation parameter specificity, and an energy threshold.

Abstract: The present disclosure provides a medical hyperspectral image (MHSI) classification method based on a fast fully convolutional network (FCN), and relates to the technical field of MHSIs. The MHSI classification method includes: preprocessing and sampling an MHSI to obtain a training sample set; inputting the training sample set into an encoder-decoder-based FCN to train the MHSI; and inputting a to-be-classified pixel of the MHSI into a trained encoder-decoder-based FCN to obtain a classification result. The present disclosure provides the MHSI classification method based on a fast FCN. In order to resolve problems of low efficiency and insufficient performance of an existing MHSI classification method, the present disclosure designs a classification method based on the fast FCN, which avoids redundant computation in an overlapping region between image patches, greatly improving an inference speed.

Abstract: The present disclosure discloses an automatic leveling control method for a four-leg support working platform, which comprises the steps: determining the mass center position of the working platform, determining the main bearing quadrant and distinguishing active legs from the driven leg; adjusting the driven leg to weak state, controlling all legs to synchronously actuate for leveling; calculating the limit compensating actuation length of the driven leg, and performing compensating actuation until accomplishing the leveling process. The method is advantageous in: high speed, high robustness, no repeated oscillation. The mass center always stays within the bearing zone of the active legs, thus completely eliminating capsizing risk of the working platform. The compensating actuation of the driven leg ensures there is no weak leg, and hence high attitude and load-bearing stability of the working platform is achieved.
