    Variable displacement pump, accumulator and Rotary actuator

    Thanks EdDanzer. I am trying to model existing components and want to check the feasibility of an idea. The idea is to drive a variable displacement pump to charge an accumulator during some period of time and then use the energy stored in the accumulator to drive a rotary actuator. I want to...

    Knee, Hip and Ankle Angles

    Hello Everyone, Im having difficulty in understanding the hip, knee nad ankle angles as reported by gait analysis softwares. For example, a particular trial processed by visual 3d reports the the minimun and maximum ankle angles are -10.66 and 19.47 degrees respectively. What I need to know is...
