  • Development of a new rollator with a free rotating chest pad integrated with multiple sensors and investigation of its effectiveness on walk assistance

    To avoid elderly people becoming bedridden and having dementia, walking independently at home is recommended as a daily activity. However, the effectiveness of most commercial gait-training devices has not been investigated thoroughly. In this study, a new rollator with a freely rotating chest pad integrated with two angular sensors and load cells was developed. Measurements were taken during a test of five young healthy students walking with the new rollator. A motion capture system with six CCD cameras was used to record leg movements during the walking tests with the new rollator. Results of the pressing forces measured by the load cells, angles of pad rotations, knee extensions, and heel heights were analyzed, and their relationships are discussed.

  • A new SPICE model of power P-I-N diode based on asymptotic waveform evaluation

    A new SPICE subcircuit model for power p-i-n diodes is proposed in this paper. The model is based on a moment-matching approximation of the ambipolar diffusion equation. It is shown that both the quasistatic model and the lumped charge model can be obtained as ion-order moment-matching approximations while new and more accurate models can be obtained from higher-order solutions. The proposed model takes into account emitter recombination in the highly doped end regions, conductivity modulation in the base and the moving-boundaries effect during reverse-recovery, showing good convergence properties and fast simulation times. Comparisons between the results of the SPICE model and both numerical device simulations and experimental results are presented.

  • Application of a virtual trajectory to the study of Rheumatoid Arthritis using the Pendulum Knee Test

    The Wartenberg Pendulum Knee Test, which is commonly used to assess passive knee movement and evaluate spasticity in individuals with neurological disorders, has been applied as a tool to evaluate intrinsic knee stiffness and viscosity in subjects with Rheumatoid Arthritis (RA) [1]. Prior conclusions implicate clinical changes in knee stiffness and not knee damping as the source of the changes in knee trajectories in persons with RA. An improved mathematical model was applied to data from a single-subject study. It is believed that the changes in knee trajectory cannot be attributed to altered knee joint stiffness, but to as yet unexplained alterations in a virtual trajectory associated with the joint movement. The subject with RA was tested before and after administration of a CNS depressant. The results indicate that the CNS plays a role in altering the behavior of the RA subject's knee in the pendulum test.

  • Control of FES-assisted standing-up in paraplegics the role of mono- and biarticular muscles

  • Application of Nonlinear Model Predictive Controller for Fes-Assisted Standing Up in Paraplegia

    Functional electrical stimulation (FES) is a method of restoring functional movements in patients of spinal cord injury that electrically induces muscle contractions. Nonlinear dynamics of paraplegics during standing up and limits of the physiological actuators suggest "nonlinear model predictive control" as a good candidate to follow desired trajectory and maintaining standing no need to learning or tuning many parameters such as many nonlinear controllers that had been used previously. In this work, the theoretical possibility of FES assisted standing up in paraplegic patient is studied using nonlinear model predictive control approach by computer simulation. The proposed controller shows good tracking behavior for ankle, knee and hip joint angles in simulated paraplegic standing up and improves patient safety because of considering constraints in control

  • An Optimization Approach for Underactuated Running Robot

    In this paper, a systematic control method based on numerical optimization methods for a running robot which has a springs at a ankle joint mimicking biotic tendons is proposed. In the proposed method, periodic trajectories are generated in a combination of a numerical optimization method named PSO (particle swarm optimization) and a basic simplex method under several constraints, and the method is a systematic way to generate desired trajectories. For the realization of the motion, a feedback controller is then designed based on a linearized model around the trajectory. The validity of the method is evaluated by numerical simulations
