Abstract: A method includes receiving physiological data associated with a user during at least a portion of an initial sleep session. The method also includes receiving demographic information associated with the user. The method also includes receiving subjective feedback associated with at least a portion of the initial sleep session from the user. The method also includes determining a profile for the user based at least in part on the physiological data associated with the user, the demographic information associated with the user, and the subjective feedback for the initial sleep session. The method also includes determining a recommended therapy for the user and one or more recommended parameters for the recommended therapy based at least in part on a comparison between the determined profile for the user and profiles associated with a plurality of other users.

Abstract: Systems and methods for sharing convergence data between GNSS receivers are disclosed. Convergence data received at a GNSS receiver via a communication connection may be utilized to determine a position of the GNSS receiver.

Abstract: A method for estimation of relative coordinates between at least two parts of a system comprising the steps of: (A) providing each of at least two parts of the system with at least one coordinate sensor; (B) measuring a set of relevant coordinates for each part of the system; and (C) processing each measurement result performed in the step (B) to estimate the relative coordinates between at least two parts of the system. The relative coordinates are selected from the group consisting of: {relative position coordinates; relative position rate (velocity) coordinates; relative position acceleration coordinates; relative angle coordinates; relative angular rate coordinates; and relative angular acceleration coordinates}.

Abstract: A fertilizer, such as a natural grass fertilizer, having weed and grub control activity comprising steepwater and at least one of spent filter aid and biomass. Also, a process for making the fertilizer and methods for promoting plant growth, inhibiting weed growth and grub control.
