Abstract:
보행자의 다리부 등, 관절을 통하여 연결된 연결체의 다양한 운동 조건에 따라 적절하게 당해 연결체의 운동을 보조할 수 있는 시스템의 구축을 통하여, 관절의 구부리기 등을 포함하는 여러가지 회전운동할 때, 연결체의 운동 상황에 따른 적절한 토크를 연결체에 부여할 수 있는 시스템을 제공한다. 본 발명의 토크 부여 시스템은 제 1 측정 수단(6)과, 제 2 측정 수단(7)과, 기준 일량 결정 수단(8)과, 외적 토크 결정 수단(10)을 구비하고 있다. 제 1 측정 수단(6)은, 관절 주위의 다리부(연결체)의 내적 일량(w 1 )을 측정한다. 제 2 측정 수단(7)은, 다리부에 부여되는 관절 주위의 외적 일량(w 2 )을 측정한다. 기준 일량 결정 수단(8)은, 제 1 측정 수단(6)에 의해 측정되는 다리부의 내적 일량(w 1 )에 기초하여 기준 일량(w 0 )을 결정한다. 외적 토크 결정 수단(10)은, 제 2 측정 수단(7)에 의해 측정되는 외적 일량(w 2 )에 기초하여, 제 1 측정 수단(6)에 의해 측정되는 다리부의 내적 일량(w 1 )과, 기준 일량 결정 수단(8)에 의해 결정되는 기준 일량(w 0 )과의 편차를 감소하도록 다리부에 부여되는 외적 토크(T 2 )를 결정한다.
Abstract:
System to assist a person in walking, consisting of an exoskeleton to be fitted to the person comprising a plurality of articulated structures for the flexion of the lower extremities and a plurality of sensors. The plurality of sensors measures the flexion performed in the joints of the upper extremities and applies a movement that is transmitted to the lower extremities by the articulated structures depending on the measured flexion. Advantageously, the movement is generated by the individual himself or herself as he or she walks and does not require being pre-programmed.
Abstract:
Compact, portable, equipment for motor rehabilitation of a patient's upper and lower limbs that permits the execution of movements and exercises with a curvilinear trajectory in three-dimensional space, wherein the equipment comprises: a gadget configured to connect to a distal end of the patient's limb such that the patient's limb under the influence of gravity remains suspended in three-dimensional space; a robotic arm connected to the gadget; a gear system comprising a first opposite gear, a second opposite gear, a spider gear and a connection element, wherein the gear system is connected to the robotic arm via the spider gear; a first motor connected to the first opposite gear and a second motor connected to the second opposite gear; optionally two gear reduction boxes each connecting an opposite gear with the respective motor; at least one driver for the motors; virtual and/or augmented reality software; a management and control system configured to receive information from the virtual and/or augmented reality software and to control the robotic arm; and a screen, or any other suitable medium configured to display the virtual and/or augmented reality software to the patient.
Abstract:
A gait management apparatus applies stimulation to a user suffering from a neurological disease (such as Parkinson's Disease) gait dysfunction. Motion sensors are arranged to be worn by a patient, and electrical stimulation electrodes are on the legs for stimulation. A controller receives motion sensing signals, and processes these signals to generate stimulation signals for operation of the electrodes to stimulate limb movement upon detection of a gait abnormality. There may be a user actuator for user actuation of electrical stimulation, and the inputs may be a series of taps. The controller may provide signals to prevent occurrence of freezing of gait when it senses that a patient is walking or has an intention to walk. Also, it may apply stimulation at an intensity level which is insufficient for functional muscle stimulation but sufficiently high to trigger activation of efferent nerves.
Abstract:
An apparatus for assisting a rescuer in performing chest compressions during CPR on a victim, the apparatus comprising a pad or other structure configured to be applied to the chest near or at the location at which the rescuer applies force to produce the chest compressions, at least one sensor connected to the pad, the sensor being configured to sense movement of the chest or force applied to the chest, processing circuitry for processing the output of the sensor to determine whether the rescuer is substantially releasing the chest following chest compressions, and at least one prompting element connected to the processing circuitry for providing the rescuer with information as to whether the chest is being substantially released following chest compressions.
Abstract:
One object is to provide an electric vehicle in which a front wheel can run onto a step without need of an operation causing a large load to users. An electric vehicle includes: a frame; at least one front wheel and at least one rear wheel provided on the frame; a drive unit configured to produce a driving force to lift the at least one front wheel relative to the at least one rear wheel; and a control unit connected to the drive unit and configured to control the drive unit, When the control unit determines that the at least one front wheel has struck a step while a user is trying to move the electric vehicle forward, the control unit controls the drive unit to lift the at least one front wheel relative to the at least one rear wheel.
Abstract:
A method and apparatus for calculating a torque of a walking assistance device, the method including receiving a measured joint angle, obtaining a gait parameter with respect to a transition among a predetermined number of gait states based on the joint angle, obtaining a gait cycle based on the joint angle, and obtaining an output torque based on the gait cycle and the gait parameter, is provided.
Abstract:
The apparatus has a pulse sensor measuring a pulse rate of a victim and a SpO2 sensor measuring blood oxygenation. Electronics processes outputs of the sensors and determines actions of a rescuer who performs cardio-pulmonary resuscitation (CPR). A prompting device conveys the actions to the rescuer. The electronics provides a prompt that instructs the rescuer to release from a chest.
