"Wireless position, posture and motion recording and analysis system"

该应用程序要求设备在典型工作期间（通常是一个工作日）的工作活动中定量和自动计算运动学变化。肌肉骨骼疾病（MSDs）主要是由运动、姿势和重复以及社会心理压力引起的。最近的研究表明，即使是非常熟练的操作员，他们的手势也会发生变化，这可能会降低MSD的风险。重要的是，模型考虑到工人的真实姿势和运动变化。需要一个基于三摄像头视频和频率可变的SIMI运动系统来支持这项重要的研究，以及八个无线2D倾角仪（用于背部，上臂，前臂和手），不需要与CAPTIV L7000分析系统进行视觉接触和接口。这些将补充现有的传统视频设备和分析工具：CAPTIV L2100软件对观察到的视频进行定性时间分析（但不能定量捕获角度变化），CAPTIV L3000具有力传感技术（线性张力压缩传感器，指尖大小的力传感电阻）。与此处提出的以工作为中心的研究不同，距离2至3小时车程的机构的VICON或OPTOTRAK系统仍然对受控实验室研究感兴趣。有了所需的设备，可以在工作现场或实验室记录定量和精确的数据分析。

This application requests equipment to quantitatively and automatically calculate kinematic variations during working activities over a typical working period (normally a working day). Musculoskeletal disorders (MSDs) are principally a function of motion, posture and repetition, as well as psychosocial stresses. Recent research has shown that even highly skilled operators include variations in their gestures which can moderate MSD risk. It is important that models account for the real posture and motion variations employed by workers. A three-camera video-based and frequency-variable SIMI motion system is requested to support this important research, along with eight wireless 2D inclinometers (for the back, upper arms, forarms and hands) which do not require visual contact and interface with the CAPTIV L7000 analysis system. These will complement traditional video equipment and analysis tools already available: CAPTIV L2100 software to time-analyse observed video qualitatively (but not quantitatively capture angular variations) and CAPTIV L3000 with force sensing technologies (linear tension-compression transducer, finger-tip sized force-sensing resistors). VICON or OPTOTRAK systems at institutions 2 to 3 hours drive away remain of interest for controlled laboratory studies, unlike the work-centred studies proposed here. With the requested equipment, quantitative and exact data analysis recorded can be recorded either in a work-site or in a laboratory.
