摘要： Positioning systems and methods comprise a network of transmitters that broadcast positioning signals comprising ranging signals and positioning system information. A ranging signal comprises information used to measure a distance to a transmitter broadcasting the ranging signal. A reference sensor array comprising at least one reference sensor unit is positioned at a known location. A remote receiver includes an atmospheric sensor collecting atmospheric data at a position of the remote receiver. A positioning application is coupled to the remote receiver and generates a reference pressure estimate at the position of the remote receiver using the atmospheric and reference data from the reference sensor array. The positioning application computes the position of the remote receiver using the reference pressure estimate and information derived from at least one of the positioning signals and satellite signals that are signals of a satellite-based positioning system. The position includes an elevation.

摘要： A planetary gear system (10) includes a planetary gear assembly (14) having a first planetary gear (28), a second planetary gear (32) rotatable relative to the first planetary gear, and a torquing mechanism (16). The torquing mechanism generates a torsional spring force of the planetary gear assembly to cause the first planetary gear to rotate along a first direction and the second planetary gear to rotate along a second direction, opposite to the first direction. As a result, the teeth of the first planetary gear contact teeth of a corresponding first stationary ring gear (18-1) and the teeth of the second planetary gear contact teeth of a corresponding second stationary ring gear (18-2) . The torquing mechanism, along with the configuration of the planetary gear assembly, minimizes or eliminates the presence of gaps between the contacting teeth of the planetary assembly and the stationary gear rings (18) and minimizes backlash within the planetary gear system.
