  • Publication number: 20240228336
    Abstract: A method for controlling power supplied to an ozone water generator is disclosed. The ozone water generator includes an electrolytic plate unit. The electrolytic plate unit includes an anode plate assembly composed of a plurality of anode plates, a first cathode plate assembly composed of a plurality of first cathode plates, and a second cathode plate assembly composed of a plurality of second cathode plates. In the process of electrolyzing water, the two cathode plate assemblies alternately obtain a relatively high-level signal at a short time, and the two cathode plate assemblies obtain a relatively low-level signal at other times. During the use of the ozone water generator, the scale formed on the surface of the cathode plate assembly can be removed in time, so as to ensure the electrolysis performance of the ozone water generator, without descaling by chemicals. No maintenance is required.

Covering conditions of the face image sequence are obtained. Key frame images are determined and input into a second neural network to obtain feature point heat maps that are converted into facial feature point coordinates. An objective function is constructed. A head pose corresponding to the key frame images is obtained. An eyeball position is initialized. An eyeball rotation angle of a reference gaze position is set as a preset angle. 3D coordinates of an eyeball in a reference gaze position image in a head coordinate system is solved. 3D coordinates of an eyeball in a to-be-measured image in the head coordinate system are fixed. An eyeball rotation angle is solved. A deviation angle of a gaze position is obtained.
