Devices used in this method are Bourdon tubes, flat and corrugated- diaphragms, capsules and various forms of manometers. When considering force measurement and sensing technologies for an application, engineers must take power requirements, form factors, sensor accuracy, upfront and operating costs, and other factors into their choice. The software may provide a way also in which subject and/or patient data can be entered and printed out at a later time. Fig. The nonelectric force measuring methods are history already. 5 is a block diagram of the overall system including the ergonomic keyboard, As shown in FIG. Following are the two methods of measuring low pressures. The first is in the area of affective computing. An increase in the slope of EMG signal amplitude or a decrease in the median frequency of the EMG signal are considered to be objective signs of fatigue, and these objective signs may be correlated with various characteristics of the force profile that are measured using the FMS, including but not limited to: slope, intercept, start and end of the signal, percentage change between the start and end of the signal, the total time of the repetitive motion and the ratio between the percentage change divided by the total time.
