    • This invention relates to the detection of human biovibrations using a digital signal processing (DSP) actigraph worn by the individual. Human biovibrations result from the human body having reverberations and oscillations from bodily functioning. The DSP actigraph has been shown to be able to identify heart beat and breathing of an individual. The invention includes a method comprising: recording movement data of an individual that includes biovibrations data, determining when the movement data substantially falls within a predetermined threshold representative of death, and providing a notification. The invention in at least one embodiment includes a method comprising: monitoring activity counts for zero crossing mode, above threshold mode, and proportional integrative mode, providing a notification when all three activity counts are within a respective predetermined range for a period of time.
    • 本发明涉及使用由个人佩戴的数字信号处理(DSP)actigraph来检测人类生物振动。 人体生物振动是由人体产生的,具有来自身体功能的混响和振荡。 DSP actigraph已被证明能够识别个人的心跳和呼吸。 本发明包括一种方法,包括:记录包括生物振动数据的个体的移动数据,确定移动数据何时基本上落在代表死亡的预定阈值内,并提供通知。 在至少一个实施例中的本发明包括一种方法,包括:监视过零模式,高于阈值模式和比例积分模式的活动计数,当所有三个活动计数在一段时间内在相应的预定范围内时提供通知。
