    • The present invention relates to a pregnancy monitoring system (10) and to a method for detecting medical condition information from a pregnant subject of interest (12). The system (10) comprises a fetal monitoring transducer (20) that detects fetal medical condition information,a first motion sensor unit (30) associated with the fetal monitoring transducer (20), the first motion sensor unit (30) comprising at least one first motion sensor (70, 72), a second motion sensor unit (32) comprising at least one second motion sensor (70, 72), and a control device (48) comprising an evaluation unit (50) that determines relative motion between the first motion sensor unit (30) and the second motion sensor unit (32), wherein the control device (48) selectively permits, in an enablement mode, processing of the detected fetal medical condition information when a level of relative motion between the first motion sensor unit (30) and the second motion sensor unit (32) indicates stable measurement conditions,and wherein the control device (48) selectively prevents, in a suppression mode, processing of the detected fetal medical condition information when the level of relative motion between the first motion sensor unit (30) and the second motion sensor unit (32) indicates unstable measurement conditions.

    • A heart rate monitor (40) for detecting a pulse of a person (10) employs a platform (43), a plurality of multi-axis accelerometers (41R, 41L) and a pulse detector (44). The multi-axis accelerometers (41R, 41L) are adjoined to the platform (43) to generate differential mode signals (A ZR , A ZL ) indicative of a sensing by the accelerometers (41) of physiological motion (12) of the person (10) relative to acceleration sensing axes (42R, 42L) and to generate common mode signals (A XR , A XL , A YR , A YL ) indicative of a sensing by the accelerometers (41R, 41L) of extraneous motion by the person (10) relative to the acceleration sensing axes (42R, 42L). The pulse detector (44) is operably connected to the multi-axis accelerometers (41R, 41L) to generate a pulse signal (PS)as a function of a vertical alignment of the acceleration sensing axes (42R, 42L) combining the differential mode signals (A ZR , A ZL ) and cancelling the common mode signals (A XR , A XL , A YR , A YL ).
    • 用于检测人(10)的脉搏的心率监视器(40)采用平台(43),多个多轴加速度计(41R,41L)和脉冲检测器(44)。 多轴加速度计(41R,41L)与平台(43)相邻,以产生指示人(10)的生理运动(12)的加速度计(41)的感测的差模信号(AZR,AZL) 相对于加速度感测轴(42R,42L)并且产生指示由加速度计(41R,41L)感测到人(10)相对于加速度的外部运动的共模信号(AXR,AXL,AYR,AYL) 感测轴(42R,42L)。 脉冲检测器(44)可操作地连接到多轴加速度计(41R,41L),以产生作为组合差模信号的加速度感测轴(42R,42L)的垂直对准的函数的脉冲信号(PS) (AZR,AZL)并取消共模信号(AXR,AXL,AYR,AYL)。
