Title: Magnesium recovery method and magnesium recovery apparatus
Filed: 2011-09-06
Abstract: In the magnesium recovery method and magnesium recovery apparatus, anode electrolyzed water (7a) and cathode electrolyzed water (7b) produced by electrolysis of seawater are separated, alkaline material is inputted into the anode electrolyzed water to adjust pH, magnesium is precipitated as magnesium hydroxide in the cathode electrolyzed water, and recovered, and the anode electrolyzed water after pH adjustment and cathode electrolyzed water after carbonate fixation are intermixed, and discharged in a state where a pH of the intermixed water is identical to a pH of the seawater. As a result, magnesium can be recovered from seawater while minimizing impact on the environment.

Title: Methods and apparatuses for multipath estimation and correction in GNSS navigation systems
Filed: 2013-05-02
Abstract: The present invention relates generally to methods and apparatuses for estimating and correcting for multipath in GNSS navigation systems. According to some aspects, the invention takes advantage of situations where position and estimated position error are reasonably stable so as to detect when large multipath errors are present with confidence. After detection, the slowly varying biases from multipath or other un-modeled sources can be modeled separately from the navigation state. This makes it possible to keep the measurements in the solution without biasing the navigation state and further ignores the long-term biases for use over short-term periods with minimized pseudorange error when necessary.

Abstract: A lateral acceleration control method for a missile permits short response times to commands even of great amplitude. It comprises the association of an aerodynamic control system having large lateral acceleration capability, called PAF, with a force control system close to the center of gravity, having a moderate lateral acceleration capability, but with very short response time, called PIF. The overall response to a command includes the usual response of the aerodynamic automatic pilot to which there is added the response from the force control system, such that in the presence of a constant order, after a delay equal to the response time of the PAF, the PIF is entirely available for a new action.
