A flexible printed circuit board (FPC) with an extensible element for liquid crystal display (LCD) module is provided, wherein the extensible element can extend when it is forced. It can be used for different LCD modules to achieve the purpose of simplifying manufacturing process.

A butterfly valve comprising a valve seat, a butterfly body engaging the valve seat, a shaft on which the butterfly body is keyed, an electric actuator coupled to the shaft, a torsional return spring adapted to rotate the butterfly body towards a closed position, a compression abutment spring adapted to rotate the butterfly body towards an open position, and an abutment body which causes the action of the abutment spring to stop when the butterfly body is in a limp-home position; the abutment spring having a mechanically fixed end connected to the valve body and a mechanically moving end connected to a wheel rigid with the shaft by means of the interposition of a transmission member mounted to slide within a chamber housing the abutment spring.

According to an embodiment of the present invention there is provided an apparatus for controlling a sub-system of a wind turbine. The apparatus comprises a cooling system comprising first and second heat exchangers, and a fluid circuit arranged to enable a coolant to flow between the first and second heat exchangers; and a processor. The processor is configured to: monitor one or more operational parameters of the cooling system; determine an icing risk based on the one or more operational parameters; and generate a control signal for output to the wind turbine sub-system in dependence on the determined icing risk.

A turbine assembly with a hollow aerofoil having a main cavity with an impingement tube, insertable inside the main cavity for impingement cooling of an inner surface of the main cavity, and a platform at a radial end of the hollow aerofoil, and a cooling chamber for cooling the platform arranged relative to the hollow aerofoil on an opposed site of the platform. The cooling chamber is limited at a first radial end by a wall segment of the platform and at an opposed radial second end from a cover plate. The impingement tube extends in span wise direction through the cooling chamber from the platform to the cover plate and restricts a sub-cavity of the main cavity. The wall segment includes an entry aperture for a cooling medium to enter from the cooling chamber of the platform into the sub-cavity of the hollow aerofoil.

The invention relates to a conveyance device which comprises a driving motor (12) of a lifting driving device (9) for lifting an object-to-be-conveyed support platform (2) carrying a conveyance traveling member (1) traveling on a traveling path. A control device (16) which performs control according to a detection signal of a pulse coder coupled to the motor (12) is arranged on the traveling path side other than on the conveyance traveling member (1), and a power and signal transmitting device (18) for transmitting power supply from the control device (16) to the driving motor (12) and the detection signal from the pulse coder to the control device (15) under the traveling state of the conveyance-used traveling member (1) is arranged at a set position on the traveling path.

The invention discloses a computer having a scanning function and a model generation method. The computer comprises a processor, a 3D lens and a lens support device; the lens support device comprisesa circular slide rail and a support frame used for sliding on the circular slide rail; the support frame is used for supporting and fixing the 3D lens; the 3D lens is used for shooting a target objectin the circular slide rail on the support frame from different shooting positions, so that a plurality of 3D images are obtained; the 3D images and the shooting positions are in one-to-one correspondence; for the 3D images respectively corresponding to any two adjacent shooting positions, the processor is used for identifying feature points on the two 3D images; and the two 3D images are stitchedin a manner of overlapping the same feature points. According to the computer having the scanning function and the model generation method disclosed by the invention, the 3D model can be obtained; furthermore, the process is convenient and rapid; images are relatively clear; and the implementation device is simple and cheap.
