美国DSI (Data Sciences International )
美国DSI 成立于1984年.
DSI生理无线遥测系统，将生理讯号侦测器埋入植入体中，以外科手术的方式植入动物体内，待动物伤口愈合后，以磁性开关启动动物体内的无线发射器，将测得之生理讯号送出，由外界之接收器收集，然后传输到计算机系统中显示、储存，与分析。 由于讯号发射器是在动物体内，接收器是在外界，因此这是一个无线的传输，也就是说实验动物是不受圈炼的、完全可以自由移动的；另外，动物也不需要开肠剖肚，没有伤口感染的问题，也没有麻醉药物对实验药物或生理反应的干扰与影响。而计算机系统部份，也可牵线到另外一个房间，让实验动物可以完全控制在所需的明暗、温湿度，以及隔音环境中，使得所收集到的生理讯号可以呈现出最真实的生理反应。
DSI, founded in 1984, is the global leader in implantable telemetric (wireless) physiologic monitors for use by life science researchers primarily to accelerate assessment of pre-clinical drug discovery and safety and to speed basic research in academic, medical device and government markets. Commonly measured parameters include arterial blood pressure, ECG, EEG, body temperature and activity levels.

In 2006, DSI purchased Ponemah. Ponemah distributes non wireless sensor systems and is the established leader in the advanced acquisition and simultaneous analysis of physiologic data from a broad array of sensor systems.

The combined offering of DSI and Ponemah yields significant value for life science researchers in terms of increased speed of discovery and safety assessment as well as reduced overall costs.
