摘要： The present invention discloses a path planning method, including the following steps: establishing an empirical map and a corresponding episodic cognitive map using a RatSLAM algorithm based on an episodic memory model; extracting a road edge in a historical memory image with a Canny operator; performing conversion to a world coordinate system from a pixel coordinate system based on the road edge, and preliminarily judging connectivity according to slope of the road edge; continuously injecting energy into the potential path detection network according to continuous observation of a potential path, so as to further judge the road connectivity; fusing the detected potential path and the original episodic cognitive map, and correspondingly updating the empirical map; and planning a path based on the updated episodic cognitive map. The potential safe path in an environment may be detected, and a better path may be planned based on the updated episodic memory model.

摘要： The invention provides a compound-pendulum up-conversion wave energy harvesting apparatus, comprising a shell floating on the water surface and swinging with fluctuation of waves, a compound-pendulum mechanism rotatably arranged in the shell and rotating with its swinging, a driving gear rotatably arranged in the shell and rotating synchronously with the compound-pendulum mechanism, an electromagnetic power generation mechanism arranged in the shell and configured to be meshed with the driving gear for transmission to generate electricity through electromagnetic induction, and a piezoelectric power generation mechanism arranged in the shell and configured to be deformed during its rotation to generate electricity through piezoelectric effect. When the shell swings un-directionally with fluctuation of the waves, the compound-pendulum mechanism makes un-directional rotation that adapts to the dynamic changes of water surface wave energy. The electromagnetic power generation mechanism and the piezoelectric power generation mechanism convert energy through two different electromechanical coupling transduction mechanisms.

The cerebral function state evaluation device evaluates a patient's motor ability based on brain hemoglobin information. By using the proposed evaluation device, an evaluation result can be given only if a patient completes several required actions. The device is inventive and simple to operate, and subjective factors in the process of the scale scoring can be avoided.
