Abstract: The invention discloses a bicycle bell having a mountable positioner, comprising a fixing element (3) for fixing the handle of the bicycle, a sound element (1) for generating a bell, and a sound trigger for striking the sound element (2); characterized in that, when the sound element (1) and the sound trigger (2) are combined, an accommodation chamber (107) is formed between the sound element (1) and the sound trigger (2), and the accommodation chamber The positioning device (4) of different sizes can be installed, and a waterproof rubber ring (204) is built in the accommodating chamber.

Abstract: A pixel electrode (30), a pixel structure (001) comprising the pixel electrode (30), a display panel (00) and a display device, relating to the field of display technology. The pixel electrode (30) comprises a strip-shaped first electrode (301) and a plurality of strip-shaped second electrodes (302), each of the second electrodes (302) being connected to the first electrode (301), and the plurality of second electrodes (302) being arranged along an extending direction of the first electrode (301). Compared with the second electrodes (302), the first electrode (301) has a longer length and a wider width. As the width of the first electrode (301) is relatively wide, even if the length thereof is relatively long, the first electrode (301) is not prone to fracture.

Abstract: Preferred embodiment systems of the invention use a scalable number of cameras that can image a volume of interest from plurality of angles. The volume can be large and illuminated with general non-coherent illumination. Synchronized cameras process data in real time to addresses particle overlap issues while also increasing observable volumes. Systems of the invention also use higher frame rate cameras to increase the amount of particle travel in each frame. Approaches of the invention alleviate the concerns with additional data accumulation by conducting image processing and segmentation at the time of acquisition prior to transfer from a camera to eliminate a data transfer bottleneck between camera and computer and eliminate a data storage problem.

Abstract: A process for the conversion of organic waste to biofuel is provided comprising cultivating organisms in the aqueous product of the HTP conversion process.

Abstract: A particle separation device for removing particles from a fluid. An embodiment of the device includes a particle separation chamber with an annular tunnel. A plurality of inlet vanes extend within the annular tunnel for imparting a helical fluid flow by deflecting the fluid at an discharge angle. The vanes are shaped so that a deflection angle of the fluid moving along a surface of the inlet vanes varies smoothly from an initial axial direction as the fluid enters the vanes to the discharge angle as the fluid exits the vanes. A particle separation system includes a plurality of particle separation modules arranged in an array. A multi-annular particle separation apparatus includes a plurality of concentric particle separation devices.
