简介:摘要:响应国家优生优育政策及女性对产后健康意识的提高,医院及女性对产后康复的重视程度越来越高,传统的产后康复项目主要是通过固定的治疗方案来做盆底康复治疗,治疗的处方主要是单一频率,单一波群的电刺激脉冲波对盆底肌进行电刺激治疗,但不同症状的患者使用单一的治疗方案效果并不理想。通过医疗器械技术及临床研究的发展,最近几年推出了集合评估-治疗的生物刺激反馈仪,目前主要是通过采集肌电及压力通道来评估盆底肌各个肌肉群的情况。该论文主要是研究如何通过人体腔内(阴道或肛门)专用生物反馈肌肉刺激探测器捕捉和测量盆底肌肉群在收缩和放松过程中的峰值肌电(EMG),通过肌电图的变化展现在显示器上,让患者感知、理解这些信号,并根据这些信号学会在一定范围内通过意识调控骨盆底肌肉的活动的仪器。

简介:针对高速水声通信信道稀疏特性,提出了一种凸组合实时判决反馈盲均衡算法。将盲均衡器分为保持均衡器支路和稀疏均衡器支路,以保持均衡器能量和权系数的瞬时梯度为判据,对稀疏均衡器支路对应抽头进行实时稀疏化处理。算法中避免设置稀疏化阈值,对不同稀疏水声信道和通信信号具有通用性,且对于时变稀疏水声信道可以利用保持均衡器支路恢复稀疏均衡器支路置零抽头系数,使算法对信道具有较强跟踪和冷启动能力。典型稀疏水声信道条件下的仿真结果证明,凸组合实时判决反馈稀疏水声信道盲均衡算法性能稳健,与全阶判决反馈盲均衡算法相比,计算简单,收敛速度快,稳态剩余误差小,有利于算法在水声通信系统中的推广应用。
