A polarized light irradiation apparatus, having at least two plane mirrors, is constructed to prevent reduction of the extinction ratio of the polarized light that irradiates a substrate when there is a change of the direction of polarization of the polarized light that is incident on a reflecting mirror. This is accomplished by forming a protection layer on the surface of the second plane mirror, and selecting the material and optical thickness of the layer in accordance with the angle of incidence and wavelength of the polarized light so that the difference Delta of the phase shifts of the polarization P component and the polarization S component emerging from the second plane mirror satisfies the condition that Delta<=±20°. By doing this, there will be no reduction of the extinction ratio of the polarized light that irradiates the substrate W if there is a change in the polarization direction of the polarized light that is incident on the second plane mirror.

Methods and apparatus for noninvasively estimating a blood pressure are provided. A pulmonic (P) component extracted from a second heart sound (S2) signal is analyzed to obtain a number of oscillations in the P component. A predetermined relationship between the number of oscillations and PAP is used to generate a blood pressure estimate. A PCG sensor including a mechanical filter for receiving heart sounds from a chest wall is also provided. The pressure of the PCG sensor on the chest wall is adjustable.

A phase difference detector generates a plurality of signals from an input beam including orthogonal, linearly polarized object and reference beam components. The detector may be configured such that as the reference and object beam components traverse the detector, phase shifts due to surface interactions are made as similar as possible between the s-components of the reference object beams, and between the p-components of the reference and object beams. Various outputs may be formed by interfering p-components exclusively, or s-components exclusively, negating errors that may otherwise arise due to differential phase shifts between p- and s-components. Phase-shifting elements in the detector may receive beams from beam splitting surfaces where the transmissive differential phase shift between p- and s-components is adjusted to insignificance.

The invention relates to a method for the operation of a wind energy installation (100) and / or a wind farm (112) for supplying electric power to an electrical supply system (120), wherein output power, particularly active and / or reactive power (Q, P), is regulated by means of at least one power regulation module (501) of a regulatory and / or control device (131), having the steps of: prescribing a power regulation input value, determining a power regulation output value from the power regulation input value, and outputting a power regulation output value. According to the invention, the power regulation module has a P controller and an I controller and has an I-component limiter, wherein a first operating value of the power regulation input value is processed in the P controller to form a P component, a second operating value of the power regulation input value is processed in the I controller to form an I component, and a third operating value of the power regulation input value is processed in the I component limiter to form a limited I component, and the power regulation output value (P-Output) is determined using the limited I component and the P component.

Computing device, computer instructions and method for simultaneously denoizing and attenuating multiples in seismic data recorded with seismic receivers. The method includes receiving the seismic data, wherein the seismic data includes a pressure P component and a vertical Z component; separating the seismic data into up-going U wave-fields and down-going D wave-fields; calculating an up-down deconvolution R based on the up-going U and the down-going D wave-fields; generating a multiple model M based on the up-down deconvolution R; and adaptively subtracting the multiple model M from the pressure P component to obtain a corrected pressure Pfree component from which simultaneously the noise and the multiples were removed. A multiple is a wave-field that propagates from a source to a receiver and experiences more than one reflection.
