Abstract: A two layers QR code label anti-counterfeiting system includes a an outer QR code label and an inner QR code label that is arranged in a concealed manner and is paired with the outer QR code label for storage in a server. When a consumer proceeds with reading by applying an application program (APP) of a mobile phone, a QR code of the outer label is read first and after the reading, the mobile phone displays peeling off the outer QR code label to subsequently read a QR code of the inner label. The data of the two QR codes are transmitted by the mobile phone to the server for comparison with originally stored data to identify and determine genuineness or fakeness. In an attempt for determination of genuineness or fakeness for one more time or multiple times, it only needs to read the inner QR code label.

Abstract: The electricity storage and recovery system. At first, injects high-pressure gas in a high-pressure tank and then, the normal-pressure fluid from a normal-pressure tank is pumped into the high-pressure tank by a motor-driven pump so that the electrical energy is converted to high-pressure potential energy of the fluid stored inside the high-pressure tank. To recover the potential energy back to electrical energy, the high-pressure fluid flows from the bottom of the high-pressure tank to the normal-pressure tank through a turbine. The turbine in turn drives a generator to produce electricity. The pump and the turbine are of a same device running in opposite directions. The motor and the generator are also of a same device running in opposite directions.

Abstract: A hooded marine float wind power generation system includes a float platform set on a sea surface, a steel cable connecting the float platform and fixed to a sea bottom anchor to prevent undesired shining of the float platform. The float platform is provided with a wind power generator that is completely fixed on the float platform. A hood surrounds the generator to also function as a tail wing so as to make the float platform and the generator to change direction in response to wind direction and thus directly opposing to the wind to extract the most wind power and realize the best power generation performance. Due to the floating configuration of the float platform, the hood will not be tipped or damaged by side winds. Windmill blades can be made small is size and costs are thus reduced.
