Abstract: A three-dimensional (3D) geolocation system for providing the 3D coordinates of a moving person in the absence of a Global Positioning System (GPS) signal. The 3D geolocation system uses two inertial sensors configured to be positioned at the left and right foot-ankle structure and a series of sensors to measure the spatial orientation of each segment of the lower limbs (shanks, thighs, trunk) of the user. In one example, the 3D geolocation system uses two additional inertial sensors at the left and right leg-knee or thigh-hip structure as well as sensors providing information indicative of the angular positions of the left and right knee and thigh, which may be provided by an exoskeleton or orthotic devices worn by the user. This determination of the 3D coordinates of the user is performed using biomechanics information about the user from the inertial sensors combined with the knee and hip angles.

Abstract: A high-density actuator, comprising: a motor including a stator, a rotor, a rotor hub, rotor bearings, an actuator base, and rolling bearings; and a transmission positioned within the rotor hub. The high-density actuator is configured such that the transmission is located within the inner diameter of the motor. The transmission may be, for example, a cycloidal transmission, a planetary transmission and a harmonic transmission.
