Abstract: A hydraulic suspension system includes: a central control apparatus and height adjustment apparatuses respectively corresponding to wheels of a vehicle. The central control apparatus includes a housing and a moving member movably disposed in the housing and dividing the housing into a first region and a second region in a moving direction of the moving member. The first region includes a first chamber and a second chamber isolated from each other. The second region includes a third chamber and a fourth chamber isolated from each other. The first, second, third, and fourth chambers respectively communicated with the height adjustment apparatuses. The height adjustment apparatuses communicated with the first chamber and the second chamber correspond to wheels located on a first diagonal of the vehicle. The height adjustment apparatuses communicated with the third chamber and the fourth chamber correspond to wheels located on a second diagonal of the vehicle.

Abstract: A shock absorber includes a cylinder, a piston located in the cylinder and defining an upper chamber and a lower chamber in the cylinder, and a piston rod connected to the piston and a vehicle body. A fluid channel is disposed in the piston rod and in communication with the lower chamber. A fluid in the lower chamber is in communication with an outside environment through the fluid channel.

Abstract: A voice processing method, apparatus and system, a smart terminal, an electronic device and a storage medium. The method includes: obtaining audio information in a conference process; generating a call flow and a recognition flow, respectively, according to the audio information, where the call flow is used for a voice call, and the recognition flow is used for voice recognition; and sending the call flow and the recognition flow respectively. By means of the technical solution of respectively generating the call flow and the recognition flow based on the audio information, determined conference content corresponding to the audio information has more presentation dimensions and is richer, and thus the accuracy of the conference is improved, the intelligence and quality of the conference are improved, and the conference experience of users is further improved.

Abstract: Provided are a network conference convergence system and method. The network conference convergence system includes a first client, a second client, and a cloud server. The first client is configured to create or enter a first virtual conference through a first conference application; and the cloud server is configured to join the first virtual conference through the first conference application according to a first join request. The second client is configured to create or enter a second virtual conference through a second conference application; and the cloud server is further configured to join the second virtual conference through the second conference application according to a second join request. The cloud server is further configured to create a virtual conference room according to a conference room creation request and add the first virtual conference and the second virtual conference to the virtual conference room.

Abstract: A pixel arrangement structure of display panel and a display apparatus, which are used to solve the technical problem of low pixel aperture ratio of an organic light emitting diode display panel. Herein, a pixel arrangement structure of display panel includes: a plurality of sub-pixels including a first sub-pixel, a second sub-pixel, and a third sub-pixel; where the first sub-pixel, the second sub-pixel, and the third sub-pixel have a polygonal structure with different numbers of sides, and distances between any adjacent two of the plurality of sub-pixels are equal.
