The invention is designed for providing surface protection for vacuum coating parts of electric products such as mobile phone, MP3, and digital camera, etc., and is characterized by good surface effect, good performances of ultrawear-resistance, high temperature and humidity resistance, anti-cold thermal cycling and anti-yellowing, etc., wherein, RCA wear can be up to more than 1500 times, which can effectively improve the service life of electric products. The invention effectively enhances the adhesion and wearing resistant performance of the uv-curing and vacuum coating dope, solves the matching problem of the bottom and surface lacquer of the uv-curing and vacuum coating dope, and has broad university.

An engine; an air cleaner which filtrates fuel air; a turbocharger which compresses intake fuel air; an intake pipe which connects the air cleaner and the turbocharger; and an intake passage which induces the fuel air taken from an intake port at an end part to the air cleaner, are included. The turbocharger is located at a front side lower part of the engine, and the air cleaner is located under a crankcase. The intake passage extends rearward from a rear part of the air cleaner, and thereafter, bends upward.

A multi-layer, strip-type screening sheet for electric lines comprises at least a substrate layer of plastic material and at least one screening layer of electrically conductive material, in particular metal, which the substrate layer is lined with, the screening layer being provided with spacing gaps that recur at longitudinal intervals for electrical interruption thereof in the longitudinal strip direction.

The invention discloses an electric power industry ubiquitous Internet of Things security protection gateway system, method and deployment architecture. The method is oriented to a ubiquitous electricpower Internet of Things full-scene safety protection application scene. A terminal identification technology is adopted, fingerprint information of Internet of Things terminal device in a network isidentified in two modes of active detection and flow discovery, asset conditions of Internet of Things terminals in the network are identified through active scanning, visual presentation is realized, and various terminals such as a traditional PC, a dumb terminal and intelligent equipment can be effectively identified. An identity baseline is established for the identified Internet of Things terminal and approval is carried out, so that counterfeit attack protection of the Internet of Things terminal is realized. Security situation evaluation of the Internet of Things terminal can be realized, and protection suggestions and means are effectively given. By performing effective admission control on the identified Internet of Things terminal, the problems of access authentication and security management and control of massive IP devices can be effectively solved, and a user is helped to construct a secure and controllable ubiquitous power Internet of Things.

The present invention relates to associative complexes of water soluble and / or water dispersible polymers and polymeric fluorosurfactants, compositions and methods for modifying substrates to provide treated articles with surface protective properties including easier cleaning, increased stain and / or soil repellency, and increased resistance to bio-fouling and environmental contamination.

The invention discloses an explosion-proof energy-absorbing polyurea elastic coating and a preparation method thereof. The explosion-proof energy-absorbing polyurea elastic coating comprises an ingredient A and an ingredient B. The ingredient A comprises, by weight, 40-80 parts of isocyanate, 15-35 parts of polyether polyol, 0-10 parts of a chain extender and 5-15 parts of a diluent. The ingredient B comprises, by weight, 40-80 parts of amine-terminated polyether, 20-40 parts of an amine chain extender, 0-10 parts of a filler and 0-10 parts of an auxiliary agent. The invention discloses the preparation method of the explosion-proof energy-absorbing polyurea elastic coating. A coating layer obtained by spray-coating of the explosion-proof energy-absorbing polyurea elastic coating has ultrahigh strength and good flexibility, can effectively resist explosive shock wave and fragments and is especially suitable for being used as a weapon equipment composite armour and a protective coating of military facility.

A data protection system obtains data having a first content on which a first encryption has been performed and a second content on which a second encryption has been performed, the second encryption more difficult to break than the first encryption. A first content decryption unit decrypts the first content, using a first encryption method corresponding to the first encryption of the first content. A second content decryption unit decrypts the second content using a second decryption method that corresponds to the second encryption. The decrypting contents can be executed by a software, and the second content decryption unit can include one of tamperproof hardware and an apparatus that executes tamperproof software.

A vehicle with protection against the effects of an exploding land mine is provided, in which a military wheeled vehicle is provided with wheel axels and drives built into front and / or rear building blocks. The vehicle is divided into multiple building blocks, although a three block construction is desirable (i.e., a front building block, a rear building block, and a main building block). A residual mobility of a remaining portion of the vehicle is preserved, even though one of the front building block or the rear building block is separated from the main building block due to the explosive shock wave generated by driving over and detonating a land mine, because each of the front building block and the rear building block has a drive for rotating the wheel axel connected to the block.
