This invention provides a washing machine, an automatic dispenser, and a control method thereof. The automatic dispenser uses an ultrasonic generator to emit ultrasonic waves; an upper reflective surface is located above the nozzle; an oblique reflective surface is located below the nozzle. After passing through the oblique reflective surface, the ultrasonic waves form an upward-propagating wave, and after passing through the upper reflective surface, they form a downward-propagating wave. The upward and downward waves superimpose to form a standing wave. The vertical distance between the ultrasonic generator and the upper reflective surface satisfies the resonant cavity condition. The nozzle is located at the acoustic pressure node of the standing wave. The controller acquires the droplet mass that the maximum acoustic levitation force of the ultrasonic wave can support, obtains the dispensing mass, and calculates the target number of dispensing droplets based on the droplet mass that the maximum acoustic levitation force of the ultrasonic wave can support and the dispensing mass. When the counting detector detects that the number of droplets has reached the target number, the nozzle is controlled to stop dispensing droplets. This invention is based on acoustic levitation technology, has a relatively small error, and high dispensing accuracy, offering significant advantages for dispensing concentrated liquids.

This invention proposes an intelligent remote emergency rescue management system capable of rapidly matching resources, relating to the field of remote emergency medical technology. The alarm receiving module triggers the case analysis module to generate priorities, the resource scheduling module allocates instructions to the drone control module, and after the drone completes deployment, the information matching module generates navigation information. Data from the person scanning the code is fed back to the system via the data association unit, forming a complete closed loop of resource scheduling-deployment-feedback. Through real-time data interaction between modules, the traditional emergency resource matching time is shortened from 10-20 minutes to within 2 minutes, while simultaneously improving the accuracy and utilization rate of drone AED deployment, achieving a qualitative leap in emergency response efficiency.

The invention discloses a device activating and binding method and a device activating and binding system, and solves or improves the technical problem that the user experience is reduced due to the fact that the user experience is not good after intelligent commodities are purchased in the prior art. According to the equipment activation and binding method provided by the invention, the installation and activation of the target commodity are both completed by a deliverer, a user does not need to install and subsequently use by himself / herself, and only needs to directly log in at a user side, so that the situation that the user does not install and activate the target commodity due to trouble is avoided, and the user experience is improved. Therefore, the invested and unused sinking cost of suppliers is greatly reduced. Besides, the standard verification information of the target commodity is set, after the deliverer delivers the target commodity to the delivery address of the target commodity, the actual verification information is obtained on site, and the target commodity is installed and activated only when the standard verification information is matched with the actual verification information, so that the delivery accuracy and the accuracy of the target commodity are improved, and the delivery efficiency of the target commodity is improved. Therefore, the phenomenon of wrong address delivery or wrong commodity delivery is avoided, and the user experience is improved.
