歌尔股份获专利，通过连续脑电帧校准时间戳

11月6日，歌尔股份（002241）的发明专利《数据时间戳生成方法、系统及终端设备》获授权，申请号为CN202610993573.1。

脑电采集端与接收端之间可能出现传输延迟、抖动或偏移，把每帧机械地按固定理论间隔打上时间戳，未必能反映实际采集顺序。方案先记录连续多个数据帧的到达时刻，求出相邻间隔并加以平滑，形成后续打戳使用的时序基准。处理对象是脑电数据传输中的时间对齐问题，目的是缩小记录时间与真实采样时序之间的偏差。

截至此次授权消息披露时，歌尔股份今年获得的各类专利授权共620项，比上年同期增加8.2%。在2026年上半年，公司研发投入为22.94亿元，同比减少2.53%。企业知识产权记录中，歌尔股份有限公司名下可查到11249条专利信息和59条著作权信息。
