Abstract: A system including a platform having a receptacle adapted to a bottom of a shoe or foot; securing mechanism, associated therewith; a sole for contacting a ground surface; a mechanism associated with the sole and a platform bottom, including: motor and a thrusting element, activated by the motor, the thrusting element adapted to move between the sole and the platform to apply an upward force against the platform bottom, thereby changing a platform height with respect to the sole; a sensor device adapted to associate with a lower limb, and to produce a locomotion data signal, and a microprocessor, operatively connected to the sensor device and motor, adapted to: receive locomotion information based on the signal; process the locomotion information to determine a locomotion phase, and control a timing of the mechanism, based on the determination, to change the height during a locomotion swing phase.

Abstract: A system including: (A) a device including: (a) a platform having, on a top side, a receptacle adapted to receive at least a portion of a bottom of a shoe or foot of the user; (b) a securing mechanism, associated with the receptacle; (c) at least one sole adapted to contact a ground surface; (d) a mechanism, at least partially disposed between, and operatively associated with, the sole and a bottom side of the platform, including: (i) a motor, for operatively connecting to a power source, and (ii) at least one thrusting element, mechanically associated with, and activated by, the motor, the thrusting element adapted to move, when in thrusting mode, between the sole and the platform so as to apply an upward force against the bottom side of the platform, thereby changing a height of at least a portion of the platform with respect to the sole; (B) a sensor device including a sensor adapted to associate with a lower limb of the user, and to produce a data signal related to locomotion of the user, and (C) a microp

Abstract: It is provided a system for improving locomotion of a human user, by changing an inclination or height of a stance surface of a device for donning on a leg during walking. The system includes a device, a sensor and a microprocessor. The device includes a platform which securely receives the shoe or foot of the user, a sole and mechanisms between the platform and the sole. Each mechanism has a motor and a thrusting element which changes the height of the platform relative to the sole. The sensor is associated with the lower limb, it senses the locomotion of the user and issues a corresponding data signal to the microprocessor. The microprocessor processes the locomotion information, determines the locomotion phase, and controls the mechanisms to effect changing of the inclination and/or the height of the stance surface during a swing phase. Also, the microprocessor introduces random changes thereof.
