    • An infant monitoring system according to embodiment(s) of the present disclosure includes a positioning member having a top surface, side surface, and tension strip, and an accelerometer in operative communication with the positioning member. The top surface, which may operatively contact an infant, receives and transmits infant cardiac impulses exerted on the top surface. The side surface, operatively connected to the accelerometer, has an initial angular orientation with respect to the top surface. The side surface receives the transmitted cardiac impulses and resolves a heart rate therefrom. The strip, having a substantially low bending stiffness and substantially high tension stiffness, is operatively connected to the top surface and bends longitudinally in response to infant inhalation forces exerted on the top surface. The bending causes angular deflections of the side surface with respect to the initial angular orientation. The accelerometer detects the angular deflections and resolves therefrom a respiration rate.
    • 根据本公开的实施例的婴儿监视系统包括具有顶表面,侧表面和张力条的定位构件,以及与定位构件可操作地连通的加速度计。 可操作地接触婴儿的顶部表面接收并传送施加在顶面上的婴儿心脏脉冲。 可操作地连接到加速度计的侧表面相对于顶表面具有初始的角度取向。 侧表面接收所传送的心脏脉冲并从其中分辨心率。 具有基本上低的弯曲刚度和基本上高的张力刚度的条可操作地连接到顶表面并且响应于施加在顶表面上的婴儿吸入力而纵向弯曲。 弯曲导致侧表面相对于初始角度定向的角度偏转。 加速度计检测角度偏转并从中解析出呼吸速率。
