Abstract: A generating method and a decoding method for a verification code presented in a form of dynamic recognizable two-dimensional code are disclosed. The dynamic recognizable two-dimensional code is comprising at least a 2D code, at least a recognizable image, and at least a displaying pattern. The verification code is defined by the displaying pattern and used between two electronic devices for verification purposes, and the determination of the verification code may decide whether any subsequent operation is triggered depending on an application program. The verification code provides supreme reliability by displaying various types of the dynamic recognizable two-dimensional code to radically improve interaction security between electronic devices, and facilitate interaction convenience between user and the dynamic recognizable two-dimensional code, also the displaying electronic device, as a human-machine interface.

Abstract: A displaying method for a dynamic recognizable two-dimensional code is disclosed, including: providing at least a two-dimensional code; providing at least a recognizable image; and sequentially displaying the at least a two-dimensional code and the at least a recognizable image on a display unit of an electronic device according to a displaying pattern, which defining a displaying sequence of displayed images with associated displaying duration and time interval to the next in the sequence, defined as the time lapse between a displayed image ending and a next displayed image appearing. A decoding method for a dynamic recognizable two-dimensional code is further disclosed. The present invention can display various types of the dynamic recognizable two-dimensional code by setting a two-dimensional code, a recognizable image, and a displaying pattern aiming to improve users' convenience and facilitate further interaction between electronic devices.

Abstract: A dynamic recognizable 2D-code for interaction between electronic devices is provided, applicable to a displaying electronic device displaying the dynamic recognizable 2D-code and a capturing electronic device using a camera module to capture the dynamic recognizable 2D-code displayed by a display screen of the displaying electronic device; including at least a 2D-code, a recognizable image, and a displaying pattern; wherein the 2D-code being a representation of a plurality of data in 2D-code format; the recognizable image being recognizable by human eyes and touchable when displayed on a touch screen, the touching detected by an application and triggering subsequent operations defined by the application; and the displaying pattern defining a sequence of displayed images with each displayed image of specific displayed duration, each displayed image being one of the 2D-code or recognizable image, and the dynamic recognizable 2D-code can be displayed cyclically.

Abstract: An aerodynamic vibration power-generation device is provided, including at least a brace, and at least a blade. The blade is attached to the brace at least with one side. The blade is an aerodynamic vibration element, with at least an embedded piezoelectric transducer. The piezoelectric transducer embedded in the blade includes related circuitry for electrically connecting to a load unit. When the airflow passes along the surfaces of the blade, the difference between the air speeds on both sides of the blade will generate a pressure difference on the surfaces of the blade, according to Bernoulli's Principle, and the pressure difference will cause the blade to deform and vibrate. The fluttering and the oscillation of the blade caused by the continuously changing airflow speeds will cause the embedded piezoelectric transducer to generate electricity.

Abstract: A stabilizing apparatus for a vertical axis wind turbine (VAWT) includes at least two rolling units, at least two guiding units and at least an engaging unit engaged with the guiding units to fix the relative position among the guiding units. The guiding units are symmetrically extending from the center area of the apparatus to the outer edge of the circumference of the apparatus with a housing space formed inside each guiding unit. The rolling units are uniformly housed inside the housing space of the guiding units. The inner wall of the bottom of the housing space inside the guiding unit forms a guiding track extending from the center of the apparatus to the edge of the circumference of the apparatus. The straight line connecting the starting and the ending points of the guiding track forms an angle of 0-45° to the horizon surface.

Abstract: A self-powered luminant banner is provided, including at least a brace, at least a blade, and a controller. The blade is attached to the brace with at least one side. The blade further includes at least an embedded piezoelectric transducer and at least a luminous element attached to the blade. The piezoelectric transducer embedded in the blade has related circuitry for electrically connecting to the controller so that the controller can power the luminous element and control the luminance of luminous element or store the excessive power. When the banner of the present invention is deformed or vibrates due to the airflow, the embedded transducer will transforms the mechanical energy into electrical energy to power the luminous element. In comparison with the conventional banner that requires extra lights connected to a power cable, the self-powered luminant banner of the present invention is both convenient to use and cost-effective, as well as provides safer application.
