Abstract: A method for measuring a steering angle of a steering shaft for a vehicle uses a first rotatable body that rotates together with the steering shaft at an r1 ratio and a second rotatable body that rotates together with the steering shaft at an r2 ratio. An absolute rotational angle of the first rotatable body, Ψ, can be expressed as Ψ′+iΩ, and an absolute rotational angle of the second rotatable body, θ, can be expressed as θ′+iΩ. Ψ′ and θ′ are measured using an angle sensor having a measurement range of Ω. To obtain the steering angle Φ of the steering shaft, measurement values ΨM′ and for θM′ of Ψ′ and θ′ are obtained. A plurality of θ's corresponding to the ΨM′ value are calculated from a relation between Ψ′ and θ′ to yield a θC′. By comparing the θM′ to the θC′, an i-value of the first rotatable body is obtained. The obtained i-value is then used to obtain an absolute rotational angle Ψ of the first rotatable body. Finally, from a relation between Ψ and θ, the steering angle Φ of the steering shaft is obtained.

Abstract: A forward osmosis membrane for seawater desalination and a method for preparing the same. The forward osmosis membrane has a composite membrane structure including a nonwoven fabric layer, a hydrophilic polymer layer, and a polyamide layer. The hydrophilic polymer layer formed on the nonwoven fabric layer facilitates an inflow of water from the feed water to the draw solution to enhance flux and realize high water permeability in the direction of osmosis. The polyamide layer not only secures contamination resistance and chemical resistance but also minimizes the back diffusion of salts of the draw solution in the direction of reverse osmosis. Hence, the forward osmosis membrane of the present invention is greatly useful for desalination of high-concentration seawater.
