Bulletin of the Japanese Society of Prosthetics and Orthotics ( Japanese Society of Prosthetics and Orthotics ) 39 ( 3 ) 219 - 224 2023.07

<p>We investigated the influence of wearing pressure from flexible knee orthosis on the sit-to-stand motion of patients with knee osteoarthritis. The subjects were seven patients with osteoarthritis of the knee. Knee joint flexion angle was analyzed when the sit-to-stand motion was performed by the subject wearing flexible knee orthosis with three different wearing pressures. High wearing pressure caused a significantly larger knee flexion angle compared to that when wearing no orthosis. The knee joint flexion angle increased with increasing wearing pressure. The knee joint flexion angle at the time of sit-to-stand motion increased with the increased wearing pressure of the flexible knee orthosis.</p>

Method for improving GPS high-positioning using microwave absorbers for walking movement support Reviewed International journal

Mechanical Engineering Letters ( The Japan Society of Mechanical Engineers ) 9 ( 0 ) 23-00125 - 23-00125 23-00125 2023.05

<p>This paper describes a method to eliminate multipath effects by using the shield cover of a microwave absorber to improve Global Positioning System (GPS) positioning accuracy. We studied a walking movement support system for visually impaired people. The system provides audio guidance regarding the direction of movement and pedestrian signals based on the location of the intersection and the pedestrian’s GPS position. Because a pedestrian device is a wearable terminal, we want to obtain highly accurate location information with a simple mechanism that can be comfortably worn on the body. In this study, we propose a method using a shielding cover with a microwave absorber to improve the GPS positioning accuracy in environments where multipath, a major cause of positioning error, occurs. This method does not require any modification to the hardware or software of the GPS receiver, and the multipath is prevented by adjusting only the height and position of the shielding cover. In a walking experiment using the proposed method, we confirmed that the shielding plate, set at an open angle of 90 degrees, can provide positioning without being affected by multipath in an environment where there are buildings on both sides of the path.</p>
