Publication number: 20240147125Abstract: A rotary earhanger structure of a wireless earphone includes an earhanger unit and a movable connection sleeve rotationally connected therewith. One end of the earhanger unit includes a first inclined surface portion extending obliquely in a preset rotational direction. The movable connection sleeve has a second inclined surface portion cooperatively connected with the first inclined surface portion. The movable connection sleeve is connected with an elastic member for driving the movable connection sleeve in a direction close to the earhanger unit. The external force rotates the earhanger unit in the preset rotating direction to adjust the wearing angle. When the earhanger unit is not subjected to the external force, the movable connection sleeve moves in the direction close to the earhanger unit under the force of the elastic member, so that the automatic reset function after the earhanger rotation is realized, thereby simplifying user operation and improving user experience.Type: ApplicationFiled: June 12, 2023Publication date: May 2, 2024Applicant: SHENZHEN CANNICE TECHNOLOGY CO., LTD.Inventors: Qilong ZHU, Ke CHEN, En XIE, Yunfeng ZHANG, Bin GAO

Publication number: 20240002920Abstract: Provided is a method and kit for detecting DNA methylation based on quantitative polymerase chain reaction (qPCR). The present disclosure achieves the detection of DNA methylation based on qPCR, where PCR is used to prepare fragments of different DNA methylation levels through base incorporation, and then the fragments are subjected to qPCR detection with two programs respectively to get ?Ct and establish a correspondence between ?Ct and a DNA methylation level. The method evaluates a DNA methylation level of a target gene by detecting ?Ct of the target gene. The present disclosure establishes a new convenient method for detecting a DNA methylation difference. According to verification results of experiments with lung cancer and colorectal cancer plasma samples, the method has simple operations, short detection time, and accurate and reliable results, is suitable for the detection of all types of methylated DNA fragments, and has high application values.Type: ApplicationFiled: November 2, 2022Publication date: January 4, 2024Inventor: Yunfeng ZHU

Patent number: 10601930Abstract: A lease-based heartbeat protocol method is provided. The method may include sending a heartbeat request to a server device in a lease period, and receiving a heartbeat request response from the server device; and determining a retry sending at adaptive interval in response to the heartbeat request response being abnormal, and sending a retry heartbeat request to the server device again after the retry sending interval is past, until the lease period expires or a corresponding heartbeat request response is normal. As such, two successive retry heartbeat requests can be sent at a relatively large time interval at an initial stage of heartbeat request retry. At a later stage of the heartbeat request retry, the time interval associated with the retry heartbeat requests is reduced, such that re-sent heartbeat requests can be sent at a higher speed.Type: GrantFiled: February 24, 2017Date of Patent: March 24, 2020Assignee: ALIBABA GROUP HOLDING LIMITEDInventors: Zhiyang Tang, Yijun Lu, Yunfeng Tao, Yunfeng Zhu
