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: The disclosure is directed toward a method of providing heat to a heat exchanger via a burner. The burner includes a burner assembly and a large transparent door for viewing various components of the burner assembly and/or an integral pilot system. The burner can also include a windbox to manipulate air used by the burner assembly and/or an air manipulation device to ensure a proper air flow distribution in the burner assembly. The burner can also include a fan and a housing having holes disposed therein to permit fuel to enter various portions of the burner assembly.
