Development of Computer controlled walkway (Electrical Carpet) for gait analysis and rehabilitation

新的步态分析和康复系统的想法包括视觉刺激的呈现，以指示踩踏位置和检测踩踏设备。研制了一种新颖的PC机驱动的电动人行道。配备多色发光LED显示步进目标，薄膜开关用于检测脚与器械的接触。I/O系统主要由输入信号到LED上发光和在X、Y坐标系下采集脚的踩踏位置数据组成。这些I/O信号由PLD（可编程逻辑器件）控制。该系统的电路实现为480 mm（W）× 300 mm（D）×9mm（H）的多层板作为一个单元。对于临床使用，最大尺寸为760 mm（宽）× 3300 mm（深），使用22个单元。除了基本的控制软件外，还开发了数据和主题管理软件。

The idea for new gait analysis and rehabilitation system include presentation of visual stimuli to indicate the stepping position and detection of stepping on the device . An original electrical controlled walkway driven by PC was developed. Multi colors lit LED equipped to present the stepping target and membrane switch is used to detect the foot contact to the device. The I/O system is mainly consisted of input signal to light on a LED and Data acquisition of foot stepping position with X,Y coordinate system. Those I/O signal is controlled with PLD（Programmable Logic Device). Electrical circuit for this system implemented to a multi layered board with 480mm(W) ×300mm(D) ×9mm(H) as a single unit. For the clinical use, maximum size is 760mm(w)×3300mm (D) using 22 units. In addition to the basic control software, the data and subject management software was also developed.
