Abstract: The present invention provides a concrete protective agent and a preparation method thereof, and a concrete protective film and a preparation method thereof. The concrete protective agent provided in the present invention includes the following components: water, oxalic acid, a defoaming agent, and a film-forming agent. When the concrete protective agent provided in the present invention is used for concrete protection, oxalic acid in the protective agent can react with calcium ions in concrete for in situ generation of calcium oxalate monohydrate inside and on a surface of concrete to obtain a protective film with strong adhesion to concrete. The film-forming agent in the protective agent is used as a template to adjust and control growth of calcium oxalate crystals, so as to improve waterproof performance and corrosion resistance to sulfate and chloride ions of the protective film. Preparation methods provided in the present invention are simple and practical and are suitable for mass production.

Abstract: A system for serially transmitting vital data includes first and second processors to determine first and second data, a serial communication apparatus to input third data and output serial data based upon the third data, and a memory having first and second ports accessible by the first and second processors, a first memory writable by the first processor and readable by the second processor, and a second memory writable by the second processor and readable by the first processor. The first and second processors store the first and second data in the first and second memories, cooperatively agree that the first data corresponds to the second data, and responsively cause the apparatus to employ: one of the first and second data as the third data, or parts of the first and second data as the third data, and output the serial data based upon the third data.

Abstract: A processor includes a first field programmable gate array (FPGA) having a first central processing unit (CPU) core programmed to perform a first function, and first programmable hardware logics (PHLs) programmed to perform a second function. A second FPGA includes a second CPU core programmed to perform a third function, and second PHLs programmed to perform a fourth function. A communication interface is between the first and second CPU cores. The first and second FPGAs are diverse. A portion of the first function communicates first information from the first CPU core to the second CPU core through the interface. A portion of the third function communicates second information from the second CPU core to the first CPU core through the interface, and, otherwise, the first function is substantially the same as the third function. The second function is substantially the same as the fourth function.
