Abstract: A ventilation treatment device and a ventilation-control method are provided. During use, when a headband contacts a headrest, a first valve assembly contacts a second valve assembly to open first air holes and second air holes, thereby communicating a first chamber with a second chamber, such that air from an air source into the first chamber enters the second chamber and further enters a respiratory chamber of a patient connecting apparatus for inhalation by a patient; and when the headband is separated from the headrest, the first valve assembly and the second value assembly are separated to close the first air holes and the second air holes, thereby preventing the air in the first chamber and the second chamber from flowing out through the first air holes and the second air holes, respectively.

Abstract: The present invention discloses a hydrate energy-storage temperature-control material and a preparation method therefor. The material includes a refrigerant hydrate and a cross-linked polymer. The preparation method comprises the following steps: first, preparing a refrigerant hydrate by using a high-pressure reactor, and conducting grinding, crushing and sieving to obtain hydrate particles; then, uniformly spraying polytetrafluoroethylene suspended ultrafine powder onto the surface of the hydrate particles by using an electrostatic spraying device, and putting the hydrate particles into a plasma instrument to modify polytetrafluoroethylene so as to allow free radicals to be formed on the polytetrafluoroethylene powder surface; finally, subjecting monomers to graft polymerization with the free radicals on the polytetrafluoroethylene surface under the irradiation of a high-pressure mercury lamp of UV lighting system to stabilize the structure of the material, preparing a final product.

Abstract: A servo movement control method, device, and terminal device are provided. The method includes: controlling an output shaft of the servo to rotate according to a first motion instruction; detecting whether a second motion instruction is received within a first preset time period, and re-planning a second target motion curve to a second target end position from a corresponding target position on a first target motion curve when receiving the second motion instruction; and controlling the output shaft to rotate from an actual position when receiving the second motion instruction to the second target end position according to the second target motion curve. When the second motion instruction is received, the servo is controlled to rotate from the target position to the second target end position according to the second motion instruction, so that the servo is switched from the first motion instruction to the second motion instruction smoothly.

Abstract: A set of multidimensional data is obtained. At least a portion of the set of multidimensional data is processed to generate a set of formatted data, wherein the set of formatted data comprises at least one of attributes, attribute values and statistics on attribute values. A user is enabled to select, on a graphical user interface, an analysis task to be performed on at least a portion of the set of formatted data. One or more visualizations are generated from a set of visualization types for presentation on a graphical user interface to the user. The set of visualization types comprises a first visualization type representing a relationship between two attributes whereby attribute value pairs are represented by varying colors, a second visualization type representing thematic variations over time with respect to values of at least one attribute; and a third visualization type representing values of three attributes comprising one or more histograms.

Abstract: A servo movement control method, device, and terminal device are provided. The method includes: controlling an output shaft of the servo to rotate according to a first motion instruction; detecting whether a second motion instruction is received within a first preset time period, and re-planning a second ideal motion curve to a second ideal end position from a corresponding ideal position on a first ideal motion curve when receiving the second motion instruction; and controlling the output shaft to rotate from an actual position when receiving the second motion instruction to the second ideal end position according to the second ideal motion curve. When the second motion instruction is received, the servo is controlled to rotate from the ideal position to the second ideal end position according to the second motion instruction, so that the servo is switched from the first motion instruction to the second motion instruction smoothly.
