This utility model discloses an improved driver's seat movement device, including a car chassis and a seat. A support and a slide are provided between the car chassis and the seat. The slide is fixedly installed at the bottom of the seat. A lower slide rail is fixedly installed on the front side of the support, and a lower slide block adapted to the specifications of the lower slide rail is fixedly installed on the bottom side of the slide. A hydraulic cylinder seat is fixedly installed on the outer wall of the slide. The output shaft of the hydraulic cylinder seat is a push rod. A through slot is provided on the support for the push rod to pass through, and the outer end of the push rod is fixedly connected to the car chassis. This improved driver's seat movement device, through the arrangement of various components between the car chassis and the seat, can remotely control the hydraulic cylinder seat to drive the push rod to extend and retract. Because its outer end is fixedly connected to the outer wall of the car chassis, it can pull the hydraulic cylinder seat, the slide, and the seat on its top side back and forth on the support to slide forward and backward, thereby adjusting the forward and backward position of the seat.

This invention discloses a modular, environmentally friendly metal-enclosed switchgear, specifically relating to the field of power distribution switchgear technology. It includes: a mounting box, a cabinet, a first track, a second track, a slide rail, and a floating mechanism. The cabinet comprises a rectangular shell composed of multiple plates. An elastic reset structure is provided on the inner side of the rectangular shell. The rectangular shell deforms under the pressure of the mounting box, allowing the elastic reset structure to provide elastic support for the rectangular shell in the horizontal plane, thereby compensating for the assembly tolerance between the mounting box and the slot. This invention, by providing slide rails on both sides of the mounting box, which cooperate with the first and second tracks on the inner side of the cabinet, constitutes a stable dual-track guiding system. This significantly reduces the resistance during the insertion and removal of the mounting box, achieving nearly interference-free smooth sliding, thereby greatly reducing wear on the guide surface and contact surface, and extending the overall service life of the drawer module and the cabinet.

The utility model relates to the technical field of display equipment, in particular to an LED backlight structure and a backlight device. The LED backlight structure comprises a substrate and a plurality of wire copper layers arranged on the substrate at intervals, the interval area between every two adjacent wire copper layers is a through window, a first reflecting layer is arranged in each through window, a heightening bonding pad is arranged on each wire copper layer in the length direction, and a second reflecting layer is arranged on each heightening bonding pad. The surfaces, away from the substrate, of the two heightening bonding pads located on the two sides of the through window are further electrically connected with a light-emitting chip. According to the technical scheme, the heightening bonding pad is arranged on the wire copper layer, the vertical space of the through window is enlarged on the premise that the welding yield is not affected, the first reflecting layer with high reflectivity can be conveniently arranged in the through window, therefore, the substrate cannot be exposed, the phenomenon that the substrate absorbs light is avoided, meanwhile, the overall brightness of the lamp panel can be improved through the high reflectivity of the first reflecting layer, and the service life of the lamp panel is prolonged. And the higher the height of the reflecting layer is, the higher the reflectivity is theoretically, so that the backlight module with higher light efficiency is realized.

The method comprises the following steps: 1, carrying out loading and signature preparation on a verifiable voucher VC; 2, after the loading and signature preparation of the VC is completed, the ProverEnclave enters a session starting process, and a JoinRequest message is forwarded to the VerifierEnclave through a Host application program; step 3, the Verifier Enclave is used for checking the received JoinRequest, and the Verifier Enclave is used for checking the JoinRequest; step 4, the message is forwarded to the ProverEnclave through the Host application program; step 5, the Prover Enclave checks the message, and a proof secret key for the VCCircuit is generated; 6, the Prover Enclave starts to execute a zero knowledge proof generation operation, and a Groth16 proof is generated; step 7, the Prover Enclave forwards the generated Groth16 proof to the VerifierEnclave through the Host application program, and the VerifierEnclave is used for generating the Groth16 proof and forwarding the Groth16 proof to the VerifierEnclave; step 8, carrying out zero-knowledge proof verification on the Groth16 proof by using VerifierEnclave, and carrying out zero-knowledge proof verification on the Groth16 proof; and step 9, the VerifierEnclave returns a final response through the Host application program according to a verification result. The method provided by the invention has the characteristics of high security, high privacy and decentralized identity authentication which is efficiently deployed on the lightweight RISC-V platform.

This invention provides a bond portfolio management method, apparatus, storage medium, and electronic device. The method includes: upon receiving a bond portfolio management request from a client, determining the target service category corresponding to the request; identifying a target obfuscated circuit model from among multiple constructed obfuscated circuit models; the target obfuscated circuit model being a model constructed based on a financial engineering model corresponding to the target service category; sending the target obfuscated circuit model to the client, enabling the client to process the bond portfolio data using the target obfuscated circuit model to obtain model output results; receiving the model output results; determining the bond portfolio management result corresponding to the model output results; and sending the bond portfolio management result to the client. By applying this method, no financial engineering model needs to be used during the service process, and the user's bond portfolio data does not need to be exposed to the server, thus protecting model data security and user data privacy.
