A system of predicting the time of parturition in the chimpanzee was developed to assure care of the newborn as soon as possible after delivery. To quantify activity, the number of times that a parturient chimpanzee crossed a sensor marker of a TV monitor was recorded by a videosensor on the market for crime prevention. The amount of activity increased remarkably just prior to parturition. A system using a personal pocket alarm ("beeper"), which rang automatically when the number of crossings by the chimpanzee exceeded a selected level within a certain period of time, was tested. In the present study, the threshold for sounding the alarm was set at 50 crossings within 10 minutes. As a result, the pocket alarm began to ring at about 40 minutes before parturition. This enabled us to be present at parturition and to tend to a newborn abandoned by its mother in one case. The present system could be useful to predict the time of parturition in the chimpanzee.
为确保在黑猩猩分娩后尽快照顾新生幼崽，开发了一种预测黑猩猩分娩时间的系统。为了量化活动量，使用市场上用于预防犯罪的视频传感器记录分娩期黑猩猩穿过电视监视器传感器标记的次数。分娩前活动量显著增加。测试了一种使用个人袖珍警报器（“传呼机”）的系统，当黑猩猩在一定时间内穿过的次数超过选定水平时，该警报器会自动响起。在本研究中，警报响起的阈值设定为10分钟内50次穿过。结果，袖珍警报器在分娩前约40分钟开始响起。这使我们能够在分娩时到场，并在一例中照顾被母亲遗弃的新生幼崽。本系统可能有助于预测黑猩猩的分娩时间。
