Abstract: A display control method determines whether a low frame rate compensation function is in an on state when a frame rate of a current frame rendered by a graphics processor is smaller than a minimum refresh rate of a display panel, performs grayscale compensation on at least one frame of display picture in consecutive n frames of display pictures of the display panel when the low frame rate compensation function is in the on state, and controls the display panel to display the compensated consecutive n frames of display pictures.

Abstract: The present disclosure discloses an acoustic input and output apparatus. The acoustic input and output apparatus may include a loudspeaker assembly, a sound-pickup assembly configured to pick up a sound signal, and a connection assembly including an elastic member, wherein a first end of the elastic member may connect to the loudspeaker assembly, and a second end of the elastic member may connect to the sound-pickup assembly. The elastic member may be configured to cause an average amplitude attenuation rate of vibrations within a phonic frequency band generated by the loudspeaker assembly to be larger than or equal to 35% in a process that the vibration transmits from the first end of the elastic member to the second end of the elastic member.

The second, third, fifth, and sixth lenses have refractive power. The fourth lens has positive refractive power and includes a convex surface facing an image side. The sixth includes a concave surface facing an object side. The seventh lens has positive refractive power. The lens assembly satisfies at least one of the following conditions: ?4<f2/f6<7; 0.7<f3/f7<1.1; ?3<f123/f4567<2; wherein f2, f3, f6, and f7 are respectively effective focal lengths of the second, third, sixth, and seventh lenses, f123 is an effective focal length of a combination of the first, second, and third lenses, and f4567 is an effective focal length of a combination of the fourth, fifth, sixth, and seventh lenses.

Abstract: A business official email box based B2B service security verification method, includes: a service platform receiving an employee account and a password inputted by a business employee, and verifying whether the employee account and the password are legal or not; if yes, transmitting a log-in verification code to a business official email box to which the employee account corresponds; the service platform receiving a verification code inputted by the business employee, and determining whether the verification code is the log-in verification code or not; and if yes, the employee account successfully logging in the service platform. The present invention uses the association between the business employee and the business official email box in order to verify the identity of the business employee by means of the business official email box, and effectively prevent a resigned employee from logging in the service platform to improve the security of the platform.

Abstract: The present disclosure relates to a waterproof open earphone. The waterproof open earphone may include a housing, at least one button, at least one elastic pad, and at least one pair of speaker units. The housing may be placed on a head or at least one ear of a user while not blocking an ear canal of the user. The at least one button may be set on the housing, wherein each of the at least one button corresponds to a button hole. The at least one elastic pad may correspond to the at least one button, respectively, wherein each elastic pad prevents the corresponding button from moving relative to the button hole. Each pair of the at least one pair of speaker units may generate sound within a frequency range from two sound guiding holes through two sound guiding tubes.

Abstract: A comment information display method is provided. In the method, a video and a comment interface are displayed. A video clip matching result of a comment content that is input via the comment interface is obtained. Target comment information including a video clip playback control element in the comment interface is displayed based on the video clip matching result including a target video clip that matches the comment content. The target video clip is played back based on a user selection of the video clip playback control element in the comment interface.

Abstract: A method for implementing service continuity, performed by a session management (SM) function (SMF) network element may include receiving a target relocation message, the target relocation message carrying target traffic routing information, the target traffic routing information comprising a target data network (DN) access identifier (DNAI) and network address translation (NAT) information, the NAT information comprising a target user equipment (UE) network address, a first application server (AS) network address, and a second AS network address, wherein a target UE corresponding to the target UE network address has established a target protocol data unit (PDU) session to a first PDU session anchor (PSA) user plane function (UPF) network element and is configured to communicate with a first AS corresponding to the first AS network address.

Abstract: A cantilever microphone includes: a substrate; a cantilever including a rotor frame and a plate covering the rotor frame, where the cantilever includes a first edge fixed to the substrate and a second end opposite to the first edge, a plurality of rotor comb fingers is attached to the plate at an edge of the plate adjacent to the second edge; and a stator fixed to the substrate or attached to a sub structure to allow some displacement from the substrate, where the stator includes a plurality of stator comb fingers, and the stator comb fingers are interdigitated with the rotor comb fingers. For the cantilever microphone, high mechanical sensitivity of the cantilever and high electrostatic sensitivity of the comb structure can be implemented, so as to increase the performance or signal-to-noise ratio of the cantilever microphone.
