Abstract: A primary optical element, a primary optical assembly, an optical assembly, a vehicle lamp lighting device and a vehicle. The primary optical element comprises a primary optical element main body comprising a light guiding portion and a fusion light-emitting portion which are provided from rear to front, a front end surface of the fusion light-emitting portion is provided as a light-emitting surface, and the light guiding portion comprises a plurality of light guiding columns, the thickness of the fusion light-emitting portion in the up-down direction greater than the thickness of the light guiding portion in the up-down direction, and the fusion light-emitting portion able to fuse light transmitted by the plurality of light guiding columns to the fusion light-emitting portion, and then emit the light by means of the light-emitting surface. The primary optical assembly, the optical assembly, the vehicle lamp lighting device, and the vehicle comprise the optical assembly.

Abstract: A high-beam optical element includes a light incident part, a light guide part and a light emitting part sequentially arranged from back to front. The light incident part includes a high-beam incident part and an auxiliary lighting structure. The auxiliary lighting structure is configured to receive auxiliary lighting and transmit it to the light guide part after at least one reflection and then project it from the light emitting part as a low-beam III. The high-beam optical element is part of a high-beam illumination unit in a vehicle.

Abstract: An optical assembly mounting structure comprising a primary optical element, a lens mount, a circuit board, and a radiator. Mounting portions on two sides of the primary optical element; each mounting portion comprising a front fitting portion and a rear fitting portion; a primary element limiting frame on the lens mount; the radiator has two C-shaped limiting structures opposite to each other; the circuit board has two C-shaped positioning grooves; the circuit board mounted on the radiator via a fitting between the C-shaped positioning grooves and the C-shaped limiting structures; rear ends of the primary optical element mounted on the radiator via a fitting between the rear fitting portions and the C-shaped limiting structures; front ends are mounted on the lens mount via the fitting between the front fitting portions and the primary element limiting frame. Also, a lighting device comprising the mounting structure, a vehicle lamp, and a vehicle.

Abstract: A continuous membrane-covered aerobic fermentation system and an application method thereof are disclosed. The system comprises: a fermentation trough which is formed by underground walls of trough, above-ground walls of trough, and a trough bottom; a membrane changing machine configured for performing membrane uncovering, membrane laying, or membrane changing treatments on a semipermeable membrane covered on the fermentation trough and materials in the trough; a pile turning machine configured for direct turning and further mixing the materials under the membrane without uncovering the membrane, and gradually shifting and conveying the materials to another fixed position; and a condensate collecting system configured for continuously collecting the condensate on a inner surface of the semipermeable membrane in real time and guiding out the condensate.

Abstract: The present invention relates to a motor, in particular to a motor allowing for quick shutdown. A motor allowing for quick shutdown includes an enclosure, an end cover, a rotor, a magnet ring and a metal ring. The metal ring is made of permanent magnet material, and the magnet ring and the metal ring are adjacent to each other and can interact magnetically with each other. Several magnetic poles, of which N poles and S poles are staggered in the circumferential direction of the magnet ring, are formed on adjacent end faces or circumferential surfaces of the magnet ring and the metal ring. One of the magnet ring and the metal ring is coaxially fixed to the rotor, while the other one is fixed to the enclosure or the end cover. The present invention has the advantages that there is no dust caused by friction, which can effectively avoid the risk of motor jammed or shortened service life, and the motor can achieve quick shutdown and output a constant magnetic damping torque when in use.

Abstract: Described herein are systems and methods of analyzing data acquired from a water plant, both historical and in real-time, making determinations about process and asset health diagnosis and anomaly detection using advanced techniques, and controlling the plant and/or providing alerts based on such determinations.
