Abstract: A micro-molybdenum-type weathering bridge steel plate disclosed by the present invention is characterized in that the steel plate is smelted from the following components by weight: C: 0.05-0.08%, Si: 0.30-0.50%, Mn: 1.25-1.35%, P: 0.010-0.014%, S?0.003%, Nb: 0.020-0.030%, Ti: 0.010-0.020%, V: 0.040-0.050%, Cu: 0.25-0.40%, Ni: 0.25-0.35%, Cr: 0.45-0.55%, Mo: 0.03-0.08%, Alt: 0.020-0.040%, and the balance from Fe and impurities. Less content of molybdenum reduces the production cost of the steel plate, the yield strength of the steel plate is 500-600 MPa, the yield strength ratio is ?0.85, and the maximum thickness of the steel plate can reach 80 mm.

Abstract: Systems and methods for interactive mobile fitting of hearing aids are provided. The method includes a mobile device receiving a reduced size fitting data set having a set of sampling points from a hearing aid. The method includes interpolating the reduced size fitting data set into a continuous fitting curve presented at a display of the mobile device with user interface objects that each correspond with one or more sampling points. The method includes receiving a user input manipulating a user interface object. The user input adjusts a value of sampling point(s) corresponding to the user interface object to generate an updated reduced size fitting data set that is communicated to the hearing aid. The method includes generating a substitute complete fitting data set based on the updated reduced size fitting data set for application to input audio to generate modified audio that is output from the hearing aid.
