Abstract: The irregularly-shaped display panel comprises a plurality of pixel units arranged in an array and a shielding layer. some of the pixel units are shielded by the shielding layer to form irregularly-shaped pixel units, and each of the irregularly-shaped pixel unit at least comprises a first irregularly-shaped pixel unit; in the first irregularly-shaped pixel unit, the areas of opening regions of at least two sub-pixels shielded by the shielding layer are different, and the sub-pixel having a larger area of an opening region shielded by the shielding layer has a greater pixel pressure difference.

Abstract: A well cementing method is described for improving cementing quality by controlling the hydration heat of cement slurry. By controlling the degree and/or rate of hydration heat release from cement slurry, the method improves the hydration heat release during formation of cement with curing of cement slurry, improves the binding quality between the cement and the interfaces, and in turn improves the cementing quality at the open hole section and/or the overlap section. The cementing method improves cementing quality of oil and gas wells and reduces the risk of annular pressure.

Abstract: A baby care device is disclosed, which comprises a base and a seat holder, wherein the base is connected to a base cover, a plane arc motion mechanism is arranged between the base cover and the base, and an output end of the plane arc motion mechanism is connected to a vertical lifting motion mechanism; a bottom end of the seat holder is connected to an output end of the vertical lifting motion mechanism, and a top end of the seat holder penetrates through the base cover to be connected to a rocking chair frame device; and the plane arc motion mechanism and the vertical lifting motion mechanism work to drive the rocking chair frame device to make three-dimensional combined movements.

Abstract: A swing control method is disclosed. Dual photoelectric sensors and gratings are involved. The method includes: detecting the time when blocked or opening parts of gratings pass through photoelectric sensors; comparing a minimum time value with a time value corresponding to a preset swing amplitude in each swing cycle, and when the minimum time value is not equal to the preset time value, generating a control signal for adjusting an output power of a motor so that the swing amplitude reaches the preset swing amplitude; detecting a current swing direction; and determining whether the current swing direction changes, and if yes, generating a control signal for adjusting the output power of the motor for co-direction supplementary augmentation. The method controls the swing speed of a swing by calculating a value of the time when the blocked or opening parts of the gratings pass through the photoelectric sensors.

Abstract: A collaboration system includes a remote server system and one or more client devices connected to the remote server system, at least one of which being a first client device that includes a touch screen display. Upon receipt of a user instruction, the collaboration system opens a document at the first client device and displays the document on the touch screen display to a first user. The collaboration system detects a first comment on the document from the first user through interacting with the touch screen display. The collaboration system receives a second comment on the document from the remote server system. The second comment is generated by a second user of a second client device and transmitted to the remote server system through a computer network. The collaboration system displays, concurrently, the first comment and the second comment on the touch screen display.
