Publication number: 20230143033Abstract: A method for vehicle rental, an electronic device, and a computer storage medium are provided. The method includes the following. A vehicle rental request is received, wherein the vehicle rental request is at least indicative of a pickup location and a rental time of a user. Whether there exists a vehicle to-be-rented matched with the vehicle rental request at a rental outlet is determined in response to determining that there is no vehicle to-be-rented matched with the vehicle rental request at the pickup location, wherein the rental outlet is pre-selected by a user or determined based on a predetermined range from the pickup location. The vehicle to-be-rented at the rental outlet is determined as a rented vehicle in response to determining that there is the vehicle to-be-rented at the rental outlet. A task of vehicle delivery is sent to an electronic device associated with the rental outlet.Type: ApplicationFiled: December 31, 2020Publication date: May 11, 2023Inventors: Hongren Shi, Yanan Song

Publication number: 20220097274Abstract: A method for directly preparing a foamed polylactic acid (PLA) product from a PLA melt includes PLA melt preparation, feeding, and two-stage extrusion. In the two-stage extrusion, a pressure at an outlet of a first-stage twin-screw extruder is 15 MPa to 17 MPa, a PLA melt is fed at a rate of 250 kg/h, a foaming additive is fed at a rate of 7.5 kg/h to 10 kg/h, and a foaming gas is fed at a rate of 2.8 L/h to 7.5 L/h. The method can ensure both foamability and quality of a material and reduce more than ? of energy consumption; and an obtained product has an adjustable foaming rate of 3 to 25, a crystallinity of 40.3% to 48.5%, a tensile strength of 8.7 MPa to 19.6 MPa, and an apparent density of 0.05 g/cm3 to 0.4 g/cm3.Type: ApplicationFiled: July 18, 2019Publication date: March 31, 2022Applicant: CHTC BIO-BASED MATERIAL ENGINEERING & TECHNOLOGY(NINGBO) CO., LTD.Inventors: Yanan SONG, Lejun WANG, Weiwei HUANG, Zongqiang ZHENG, Yining LIU

Publication number: 20220088840Abstract: A preparation method of a high-rate foamed polylactic acid (PLA) sheet includes first-stage extrusion, second-stage extrusion, and foamed sheet extrusion. The method requires the following raw materials in parts by mass: 88 to 94 parts of PLA, 1 to 2 parts of a nucleating agent, 2 to 5 parts of a foaming agent, and 2 to 5 parts of an additive. The new method effectively solves the problems of low foaming rate, low strength, and the like in the industrial production using carbon dioxide, and a prepared PLA sheet with high foaming rate and excellent surface performance can be used in the fields of food packaging, disposable fully-degradable lunch boxes, and the like.Type: ApplicationFiled: July 18, 2019Publication date: March 24, 2022Applicant: CHTC BIO-BASED MATERIAL ENGINEERING & TECHNOLOGY (NINGBO) CO., LTD.Inventors: Weiwei HUANG, Lejun WANG, Yanan SONG, Zongqiang ZHENG, Yining LIU

Patent number: 10283104Abstract: A method and apparatus for controlling earphone noise reduction. The method for controlling earphone noise reduction can include collecting a noise signal of an environment where a terminal microphone is placed, processing the collected noise signal to generate a judgement result, and controlling connected earphones to enable a noise reduction function or disable the noise reduction function according to the judgement result. Embodiments of the present disclosure can be realized without a hardware switch for noise reduction adjustment on earphones. Embodiments of the present disclosure are capable of automatic noise reduction, thereby improving the integration degree of the earphones and also enhancing the noise reduction efficiency of the earphones.Type: GrantFiled: January 26, 2015Date of Patent: May 7, 2019Assignee: SHENZHEN GRANDSUN ELECTRONIC CO., LTD.Inventors: Yanan Song, Haiquan Wu, Ruiwen Shi, Xinian Geng, Guozhong Du, Jiayun Xu
