    Abstract : This thesis provides a standardized method to measure accuracy for engine and gearbox sensors. Accuracy is defined by ISO 5725, which states that trueness and precision need to be known to provide a metric for accuracy. However, obtaining and processing the data required for this is not straight forward. READ MORE

  3. 2. Torque Sensor Free Power Assisted Wheelchair

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Jonas Johansson; Daniel Petersson; [2007]
    Keywords : torque sensor free; power assisted wheelchair; velocity disturbance controlled; power assisting; wheelchair; digital control; assisting power; motorized; sensor free; disturbance controlled; intelligent; rotational encoder; rotary encoder; electrical motors; development board; controller card;

    Abstract : A power assisted wheelchair combines human power, which is delivered by the arms through the pushrims, with electrical motors, which are powered by a battery. Today’s electric power assisted wheelchairs use force sensors to measure the torque exerted on the pushrims by the user. READ MORE
