Dual mode impulse noise protecting earplug (D-182)

A two piece dual mode earplug including an integrally molded elongated member having a nose end and an open rear end and a channel extending through the elongated member. An integrally molded insert member is formed with a base portion and a rod portion and with the rod portion seated within the open rear end of the elongated member. The insert member additionally includes an attenuation filter integrally molded as part of the rod portion and includes first and second openings located on each side of a chamber and with the size and length of the openings together with the chamber providing attenuation of impulse noise while allowing the passage of normal speech through the channel. The insert member also includes the base portion integrally molded to have a third opening larger than the first and second openings in the rod portion and with the first, second and third openings together forming a passageway through the insert member to the channel extending through the elongated member. The insert member further includes an integrally molded cap member and with the cap member having a plug portion of a size complementary to the third opening of the base member. The insertion of the plug portion into the third opening of the base portion seals off the third opening. The positioning of the cap member provides for the earplug being in a first mode of operation where the passageway is open and a second mode of operation where the passageway is closed.

Wind power forecast method based on error correction and promotion wavelet combination forecast model

The invention discloses a wind power forecast method based on an error correction and promotion wavelet combination forecast model. According to the method, wind power history data is processed through utilization of a promotion wavelet decomposition technology, main characteristics of a power data sequence can be improved, frequency components with relatively obvious characteristics can be obtained, and the denoising effect can be achieved, thereby applying to various forecast algorithms. A suitable forecast model is selected according to the characteristics of high and low frequency components, the deficiency of a single forecast method can be removed, and the forecast precision can be greatly improved. According to the method, processing errors are corrected through utilization of an error layered analysis method. Compared with the method of obtaining a next moment error forecast value by directly using the forecast model, the method has the advantage that under the condition that relatively high fluctuation occurs in the errors, the next moment error condition and compensation strength can be analyzed precisely, the errors resulting from an error forecast process can be reduced, and the errors of the integrated forecast method can be reduced.

Special clamp for motor shell macropore series for fine boring rail train

The invention discloses a special clamp for a motor shell macropore series for a fine boring rail train. The special clamp comprises a base, a supporting post, a positioning clamping plate and a tightening bolt; the upper end face of the positioning clamping plate is provided with a positioning seam allowance, a positioning plane and a tightening fixing hole; the positioning seam allowance is matched with a phi 465mm hole on a workpiece end face A; the tightening fixing hole corresponds to a mounting screw hole on a workpiece to be processed; the positioning clamping plate is fixed on the base through the supporting post; and the workpiece is fixed on the upper end face of the positioning clamping plate through the tightening bolt. The end face A, the phi 465mm hole on the face and a lateral surface B are adopted for positioning, and the workpiece is clamped by the tightening bolt 4, so the workpiece is positioned accurately and installed stably; axial tightening and fixing are performed by using a direct screwing mode of the tightening bolt and the existing screw hole on the workpiece, and the magnitude of the tightening force does not generate stress deformation in the radial direction of the processed pore series so as to ensure the dimensional precision and the form and position precision of the processed pore series.
