Abstract:
The control method for lower-limb assistive exoskeletons assists human movement by producing a desired dynamic response on the human leg. Wearing the exoskeleton replaces the leg's natural admittance with the equivalent admittance of the coupled system formed by the leg and the exoskeleton. The control goal is to make the leg obey an admittance model defined by target values of natural frequency, resonant peak magnitude and zero-frequency response. The control achieves these objectives objective via positive feedback of the leg's angular position and angular acceleration. The method achieves simultaneous performance and robust stability through a constrained optimization that maximizes the system's gain margins while ensuring the desired location of its dominant poles.
Abstract:
Time after time studies find that often, even when administered by trained professionals, cardiopulmonary resuscitation (CPR) compression rates and depth are inadequate. Too week, shallow or too forceful compressions may contribute to suboptimal patient outcome. Several parameters are crucial for optimal and properly-administered CPR. Crucial parameters include proper hand positioning on the patient's chest, depth of compression of 4-5 cm, and compression rate of 100 compressions per minute. The crucial parameters are often affected by patient parameters, and relative to the patient, rescuer parameters, such as patient thoracic volume; weight; age; gender; and rescuer's, relative to the patient's, parameters, such as weight, height; physical form, etc. Proposed is an automated CPR feedback device with user programmable settings for assisting with real-time feedback and subsequently correcting rescuers patient customized CPR technique.
Abstract:
A walking assistance moving vehicle includes a walking assistance moving vehicle main body with a pair of drive wheels, a drive wheel rotational speed sensor, a turning sensor, and a controller. The drive wheel rotational speed sensor senses drive wheel rotational speed of each of the drive wheels. The turning sensor directly senses at least one of a first lateral acceleration and a first turning angular velocity. The controller indirectly acquires at least one of a second lateral acceleration and a second turning angular velocity based on the drive wheel rotational speed sensed by the drive wheel rotational speed sensor. The controller performs a first control to decelerate or stop drive of the drive wheels based on a comparison of the first turning angular velocity and the second turning angular velocity or a comparison of the first lateral acceleration and the second lateral acceleration.

Abstract:
A system for facilitating the effective administration of cardiopulmonary resuscitation (CPR) by providing feedback regarding release velocity, which is the velocity of the chest while resiliently expanding during the upstroke of a CPR compression cycle. The feedback is provided, indicating whether the CPR provider has substantially released the chest, through a control systems which analyzes sensor input corresponding to chest displacement to determine chest compression depth and release velocity, compares the determined release velocity to a desired release velocity threshold. The desired release velocity is determined based on the depth of compression. The desired release velocity may be determined based on assumed or target compression depth, selected by a CPR provider and input into the control system, or the desired release velocity may be determined adaptively, based on the chest compression depth achieved during compressions and/or the rate of compressions, as determined by the control system.
