Abstract: An initialization system for a personal navigation system associated with a user, including: a first reference point arrangement configured for communication with the personal navigation system of the user and to facilitate the generation of a first user data set including horizontal position and azimuth angle (x 1 , y 1 , θ 1 ); a second reference point arrangement configured for communication with the personal navigation system of the user and to facilitate the generation of a second user data set including horizontal position and azimuth angle (x 2 , y 2 , θ 2 ); and at least one control device configured to determine a common coordinate system based at least in part upon the first user data set and the second user data set. An initialization process and arrangement are also disclosed.

Abstract: A closed path infrared sensor includes an enclosure, a first energy source within the enclosure, at least a second energy source within the enclosure, at least one detector system within the enclosure and a mirror system external to the enclosure and spaced from the enclosure. The mirror system reflects energy from the first energy source to the at least one detector system via a first analytical path and reflects energy from the second energy source to the at least one detector system via a second analytical path. Each of the first analytical path and the second analytical path are less than two feet in length.
