Abstract: A box-type wind power generation device and a power generation device set is provided, the box-type wind power generation device includes a box body, a first energy collecting unit and a first connection member. The box body includes at least one flexible housing member and at least one rigid housing member which enclose at least one sealed cavity. The first energy collecting unit includes a piezoelectric membrane and electrodes deposited on both sides of the piezoelectric membrane, respectively; the first energy collecting unit overlying on an inner wall of the flexible housing member and are located in the sealed cavity. An end of the first connection member is fixed to the flexible housing member so that the first connection member is connected to the box body and at least a part of the first connection member is located outside the sealed cavity.

Abstract: A device for controlling a fluid flow comprises: a housing) with which at least a first connection port, a second connection port and a third connection port are fluidly communicated; a closure means disposed within the housing; and a rotatable actuation means configured to selectively open or close the first connection port, the second connection port and the third connection port by operating the closure means; wherein the actuation means is configured to have at least five rotation positions such that the device can achieve at least five respective different fluid flow states. Also disclosed is a set for a peritoneal dialysis comprising such a device. The device is particularly suitable to be used as a patient connector for a continuous ambulatory peritoneal dialysis (CAPD), which connector is particularly suitable for use in Point-of-Care (POC) CAPD to manage preparation of CAPD solution and use of the CAPD solution.

Abstract: An imaging cartridge chip includes a communication module for providing data communication between the imaging cartridge chip and an imaging device; a non-volatile data storage module for storing at least two different serial numbers; a volatile temporary data storage module connecting between the communication module and the non-volatile data storage module and including at least two temporary data storage units; and a control module. The control module is configured to load different serial numbers into corresponding temporary data storage units; to send a serial number in a selected temporary data storage unit to the imaging device; to determine whether the serial number sent to the imaging device passes a legitimacy verification of the imaging device; and when the serial number sent to the imaging device does not pass the legitimacy verification, to send a serial number in another temporary data storage unit to the imaging device.

Abstract: The present invention is directed to crystalline polymorphs of benfotiamine, its methods of preparation and its use thereof. Five crystalline polymorphs of benfotiamine are designated as crystalline forms A, B, C, D and E, and may be distinguished by their respective patterns of X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), infrared spectroscopy (IR), raman spectroscopy, moreover by their diverse preparing process. The crystalline polymorphs of the present invention are useful as they act in treating Vitamin B1 deficiency, metabolic disorders, mental illness and disorders, diabetes complications, neurodegerative diseases. Further the present invention is a process for preparing and transforming diverse crystalline form of benfotiamine through different synthesis routes and varied solvents and combinations. The crystalline polymorphs of the present invention are basically pure.
