Abstract: A method includes the following: a local identity verification request for controlling an in-vehicle device is sent to a first server, where the first server is configured to generate target verification information corresponding to the terminal device and the in-vehicle device for the identity verification request; the target verification information and a pre-constructed certificate chain that are sent by the first server are received, and the certificate chain and the target verification information are verified based on a predetermined key of the terminal device to obtain a verification result; and when the verification result is that the verification succeeds, a vehicle control instruction is processed based on the target verification information, and a processed vehicle control instruction is sent to the in-vehicle device, so that the in-vehicle device processes the vehicle control instruction based on the target verification information and the certificate chain.

Abstract: Disclosed is a cartridge-type rivet feeding mechanism of a flow drill screwing device including a rivet box, a magazine for storing rivets from the rivet box, a rivet pulling mechanism including a rivet pulling block, a rivet pulling block guide housing and a linear driving unit connected with the rivet pulling block, a blowing mechanism including a curved connecting tube and a third air inlet, the rivet pulling block is defined with a T-shaped through hole capable of accommodating a rivet and configured for transferring the rivet from the first connecting tube to the second connecting tube. The first air inlet and the second air inlet are both configured for introducing compressed air to push the rivet to move towards the riveter head.

Abstract: A combined bio-artificial liver support system, includes branch tubes that are connected in sequence: a blood input branch tube, an upstream tail end, a first plasma separation branch tube comprising at least a first plasma separator, a non-biological purification branch tube comprising at least a plasma perfusion device and a bilirubin adsorber, a biological purification branch tube comprising at least a hepatocyte culture cartridge assembly, and a plasma return branch tube, a downstream tail end of which is set as a blood output end.

Abstract: Provided herein is a transmission system including: a housing; a pair of double-layered gears for transmitting a power from a motor to a screw driver shaft defining a transmission axis, the pair of gears including a first bigger gear and a first smaller gear; a torque cup for covering a leading end portion of the housing through which the shaft is extended from the housing; a first set of planetary gears for driving the shaft, regularly surrounding and meshing the first smaller gear; and a first ring gear for sliding axially against the housing and meshing the first bigger gear and/or the first set of planetary gears; wherein the torque cup can be turned to force the first ring gear to slide axially.

Abstract: An e-mail processing method includes: receiving, by a server, an e-mail from a sender; if there exists a recipient that has not yet been associated with an e-mail account in the recipients of the e-mail, allocating, by the server, an e-mail account to the recipient; and sending the e-mail to the allocated e-mail account, thereby ensuring that the recipient successfully receives an e-mail of a sender and improving communication efficiency between users. An e-mail group creating method includes: detecting, by a server, an e-mail group creating demand for an instant messaging group; extracting, by the server, an e-mail address corresponding to each member contained in the instant messaging group; and generating a corresponding e-mail group, thereby automatically creating an e-mail group and helping to simplify a user's operation.
