  • Patent number: 8197425
    Abstract: A measurement device (10) for quantitatively measuring stiffness, torque or range of motion (ROM) around the joint axis of the ankle-foot complex of a lower limb in the sagittal and coronal planes, the device (10) comprising: a plate (13, 21) for placement of the ankle-foot complex, the plate (13, 21) operatively connected to an actuator (14, 16) for manual actuation; an angular measurement device (12, 17) to measure an angular position of the ankle-foot complex; a torquemeter (11) to measure resistance torque of the ankle-foot complex; an electromyograph (48) to monitor muscular activity of muscles of the lower limb; and computer software to record the measured angular position, resistance torque of the ankle-foot complex and EMG of the lower limb muscles.

  • Publication number: 20080221944
    Abstract: The method and system enable risk assessment and presentment. The assessment includes estimation of a loss probability distribution of possible losses arising from the failure of business processes. The loss probability distributions of processes can be aggregated according to respective attribute hierarchies. The risk implications of changes within an organization can be assessed due to the linking of process change and operational risk. Control effectiveness, process value at risk, and a comparison of self-assessment against independent assessment can also be measured. The presentment includes an integrated, hierarchical process view of business operations and associated operational and compliance risks and controls, including the relationship between summary level process maps and the underlying detailed level process maps. The hierarchy contains risk and control attributes associated with any particular process.

  • Patent number: 7331117
    Abstract: A calcaneal bisector for indicating a calcaneal bisection line of a heel firstly includes a frame and a first plate mounted relative to the frame. One side of the heel can be aligned to the first plate when the bisector is in use. The bisector also includes a second plate movably mounted to the frame, and the second plate is slidable relative to the first plate for aligning to the other side of the heel. The bisector further includes an indicator movably mounted relative to the frame for indicating the calcaneal bisection line and a transmission mechanism disposed between the plates and the indicator for correlating movements of the indicator and the relative movements of the plates so as to ascertain the calcaneal bisection line.
