Abstract: A power amplifier with clamp and feedback protection circuitry is disclosed. In one aspect, the power amplifier is initially protected by a fast-acting clamp circuit whose overall size is relatively limited. Subsequent operation allows a comparatively slowly acting feedback loop to dominate the protection of the power amplifier. By providing the two protection circuits, each optimized for a particular phase of protection, the overall size of associated protection circuitry may be diminished while still protecting the power amplifier from failure inducing conditions.

Abstract: A method for cutting side plates and end plates of a scrapped railway boxcar aims to improve low disassembling efficiency as it is difficult to disassemble the scrapped railway boxcar. The steps of cutting the side plates includes: A1: cutting a top of an upper side plate; A2: performing cutting downwards, dividing the upper side plate, and then cutting the left upper side plate; A3: cutting the right upper side plate; A4: cutting a lower side plate; A5: cutting off upper channel steel on columns; A6: cutting off lower channel steel on the columns; and A7: cutting the columns. The method avoids complicated working conditions of directly cutting angle iron, the channel steel, multilayer boards and closed regions, so that the cutting efficiency of the side plates and the end plates of the boxcars is improved. Moreover, automatic cutting can be realized according to a set cutting path.

Abstract: A protection circuit for an acoustic filter and/or a power amplifier is disclosed. In one aspect, the protection circuit includes a bidirectional coupler that helps secure a measurement of power at an antenna. The power measurement is compared to a threshold by a detector, and if the power measurement is above the threshold, a signal is sent that causes debiasing of a power amplifier stage, which reduces power levels of signals being amplified by the power amplifier stage and correspondingly lowers the power level going through a filter associated with the power amplifier stage. By lowering the power level going through the power amplifier stage and the filter, both elements are protected against over power conditions allowing functionality to be maintained.

Abstract: An imaging correction unit and an imaging module are provided. The imaging correction unit has an optical axis and includes four wedge optical elements with the same structure.

When a beam transmitted along the optical axis of the imaging correction unit passes sequentially through the wedge optical elements and is imaged at a center of an imaging surface, the symmetry axis of any one of the four wedge optical elements is at an angle of 90 degrees relative to the symmetrical axis of one of adjacent wedge optical elements.
