1. A force sensing module for measuring weight in the presence of longitudinal and lateral torques, comprising:

  • at least two sets of strain gauges, said sets of strain gauges spaced apart from each other and in vertical alignment, said strain gauges configured for being connected at a first end thereof to a vertical support and at a second end thereof to an arm, each of said strain gauges thereby sensing and providing respective output signals indicative of a load on the vertical support and a torque acting on the arm; and

    output signal combining means combining and adjusting said output signals to minimize a longitudinal torque response.
