Abstract: The present invention relates to an intelligent wind turbine generator, which comprises a first blade module, a second blade module, a power generating module, and a control module. The second blade module is disposed at the first blade module. The power generating module is connected with the first and second blade modules. The control module is connected with the power generating module, the first blade module, and the second blade module. The first and second blade modules rotate, driving the power generating module to generate power. The control module detects a voltage value generated by the power generating module and judges if the voltage value is greater or lower than a predetermined value. The control module controls whether the first and second blade modules overlap or not. The intelligent wind turbine generator is able to switch automatically the blade number of the wind turbine generator.

Abstract: An apparatus and a method for measuring fluid viscosity are revealed. An inlet end of a container is larger than an outlet end of the container. A fluid flows through the outlet end at a flow rate. A volume of the fluid flowing out of the outlet end is measured by a graduated cylinder while the time taken for the fluid to flow through the outlet end is measured by a timer. The flow rate is associated with the volume and the time of the fluid and the viscosity of the fluid is obtained according to a density and a pressure gradient of the fluid, an outlet end radius and the flow rate. The apparatus has simple structure, easy operation and maintenance. Moreover, less space is required and the apparatus cost is low. Therefore, the testability is improved, the measurement time is reduced, and the convenience in use is enhanced.

Abstract: An apparatus for measuring viscosity includes a container in which an inlet radius of an inlet end is larger than an outlet radius of an outlet end. A fluid with a flow velocity is placed in the container. The fluid has a density value and a pressure gradient value. A pressure controller for controlling the pressure gradient value of the fluid is connected to the inlet end and the outlet end. A flow meter measures the flow velocity. A viscosity of the fluid is correlated with the density value, the pressure gradient value, the inlet radius, the outlet radius and the flow velocity. After being applied to various fluids, the present invention improves testability. Moreover, the measurement time is reduced due to simple structure. The maintenance is easy and the operation is not complicated. Furthermore, less space is required, the cost is down and the measurement error is reduced.

Abstract: A surface tension measuring device and a method thereof are revealed. The surface tension measuring device includes a container and a hole. A liquid analyte is filled into the container and the hole is disposed on a wall surface of the container while the liquid analyte forms a drop on the hole. The surface tension of the liquid analyte is correlated with an internal gas pressure inside the container, an external gas pressure outside the container and a level of the liquid analyte. Thus the surface tension of the liquid analyte is obtained by control of the increasing of the liquid analyte level or pressure difference inside and outside the container. Therefore, the reduction of measuring time, less space occupied, lower equipment cost and reduced operation complexity are achieved.
