A multichannel recording system is described which offers the advantages of accuracy and low cost. The system was a commercially digital printer and clock mechanism. Switch decoding circuitry is presented in the article. The system described will reocrd from 200 switches connected to egg trip levers on bird cages. An example of data obtained from two Japanese quail illustrates the smooth patterns of lay seen when recorded to one minute accuracy.
本文描述了一种具有准确性和低成本优势的多通道记录系统。该系统由一台商用数字打印机和时钟机构组成。文章介绍了开关解码电路。所描述的系统将记录连接到鸟笼蛋触发杆上的200个开关的数据。从两只日本鹌鹑获得的数据示例说明了以一分钟的精度记录时所看到的平滑产蛋模式。
