Abstract: A method for recycling waste polyester, in particular to a method for recycling waste polyester by a modified alcoholysis method to recycle waste polyester to prepare dimethyl terephthalate (DMT), is provided and belongs to waste polyester recycling technology field. The waste polyester after dewatering and deoxygenation treatment is used as a raw material, in the step of feeding in melted state the alcoholysis agent is added in the melted waste polyester for preliminary alcoholysis, and the alcoholysis agent is ethylene glycol. On one hand, alcoholysis reaction occurs when the waste polyester raw material are melted, and at the same time, the viscosity of the melted material is reduced. Thus, the melted material remains melted at the alcoholysis temperature and is not easy to solidify again after entering the alcoholysis tank, ensuring that the alcoholysis is carried out under homogeneous conditions.

Abstract: In various examples, high beam control for vehicles may be automated using a deep neural network (DNN) that processes sensor data received from vehicle sensors. The DNN may process the sensor data to output pixel-level semantic segmentation masks in order to differentiate actionable objects (e.g., vehicles with front or back lights lit, bicyclists, or pedestrians) from other objects (e.g., parked vehicles). Resulting segmentation masks output by the DNN(s), when combined with one or more post processing steps, may be used to generate masks for automated high beam on/off activation and/or dimming or shading—thereby providing additional illumination of an environment for the driver while controlling downstream effects of high beam glare for active vehicles.
