A droplet delivery device includes a housing with a mouthpiece port or outlet from a nasal device for releasing fluid droplets, a fluid reservoir, and an ejector bracket having a membrane positioned between a mesh with a plurality of openings and a vibrating member that is coupled to an electronic transducer, such as an ultrasonic transducer. The transducer vibrates the vibrating member which causes the membrane to push fluid supplied by the reservoir through the mesh to generate droplets in an ejected stream released through the outlet.

The present provides a visual positioning method and system based on a Gaussian process and a storage medium. The method includes: collecting image of surrounding environment and moving trajectory points while traveling (S); extracting global features and semantic features from images (S); processing the extracted global features and semantic features and the moving trajectory points according to a preset processing rule to obtain a Gaussian process observation model (S); and reconstructing a Bayes filtering framework according to the Gaussian process observation model, endowing a current trajectory with an initial position point, and generating a next position point of the current trajectory, the next position point being used for providing a positioning guidance for navigation (S). An association between a current state and a historical state can be established, so that the accuracy of a predicted next position point is improved, and accurate navigation can be provided for a robot motion.

An adjustment method for LED backlight brightness, comprising the following steps of: if the current LED backlight brightness is greater than a preset value, maintaining the PWM duty ratio as the maximum value, and adjusting the LED backlight brightness by adjusting an LED conduction current (S); and if the current LED backlight brightness is not greater than the pre-set value, maintaining the LED conduction current to be constant, and adjusting the LED backlight brightness by adjusting the change of the PWM duty ratio between the maximum value and the minimum value (S). This method can improve the light-emitting efficiency of LEDs, reduce backlight loss, and reduce the noise generated by an LED drive circuit.
