WIRELESS DIGITAL POLYGRAPH LINK WITH ERROR CORRECTION

我们将开发一种无线数字测谎仪， 数字纠错，这将保护传输的生理 测量信号来自噪声退化和来自由 当他们被监视时，他们四处走动。 我们将添加 无线数字链接到一个微型的，电池供电的16通道 一种基于微处理器的数字测谎仪，以前在PHS下开发 SBIR第二阶段赠款。 利用现有的设备，无线数字链路将使 真正的无线测谎仪监控 它将开辟新的领域， 涉及婴儿和儿童、自由活动的受试者 锻炼的主体，不合作的主体，以及必须 在实验室外研究。 现在没有合适的设备。 现有的测谎仪太大，需要连接电缆。 一些 具有多通道测量功能的独立移动式监护仪 能力，但它们的使用本质上受到其内部 数据存储能力。 无线设备避免这些大小和数据 存储限制;但是，很少有可用设备具有足够的通道 作为一个实用的，通用的研究工具，大多数采用 麻烦的模拟传输方法，没有一个具有模块化 测量能力。

We will develop a wireless digital polygraph link with sophisticated digital error correction, which will protect transmitted physiological measurement signals from noise degradation and from dropouts caused by subjects moving around while they are being monitored. We will add the wireless digital link to a miniature, battery-operated 16-channel microprocessor-based digital polygraph previously developed under a PHS SBIR Phase II grant. With the existing device, the wireless digital link will make possible true wireless polygraphic monitoring. It will open up new areas of investigation involving infants and children, freely moving subjects, exercising subjects, uncooperative subjects, and subjects who must be studied outside the laboratory. No suitable equipment is now available. Existing polygraphs are too large, and require connecting cables. Some self-contained ambulatory monitors have multiple channel measuring capabilities, but their use is inherently restricted by their internal data storage capacities. Wireless devices avoid these size and data storage limitations; however, few available devices have enough channels to serve as a practical, general-purpose research tool, most employ troublesome analog transmission methods, and none have modular measurement capability.
