Abstract: An advanced concrete drum cleaning system that includes a dynamically controlled oscillating nozzle, a boom zeroing function, a breakaway mounting plate, and a hydraulic assembly for enhanced safety. The system features a motor-driven nozzle having a stroke length that can be dynamically adjusted in real-time using feedback from an encoder. A controller with a user interface allows operators to precisely control and monitor the nozzle's position. Additionally, the system includes a boom zeroing function, enabling the operator to set and maintain a reference position for the boom within the concrete drum. The hydraulic assembly, consisting of lifting and lowering components, allows the nozzle housing to quickly disengage from obstructions to prevent damage. Moreover, the breakaway mounting plate provides a means for limiting damage when the nozzle housing is unable to disengage from obstructions.

Abstract: A removable tinted window panel system for an aircraft cockpit may include unique tinted panels and panel brackets which are easily installed and removed allowing full compliance with FAA regulations. The tinted panels, when installed, block 99.9% of UV radiation, reduce glare by up to 70%, reduce heat from solar energy up to 47% and thereby improve overall cockpit environment and pilot comfort. The panels allow the pilot to selectively block the sun when needed to remove glare and to remove the discomfort of being exposed to direct sunlight coming from the side windows. The panels reduce pilot fatigue, reduce eye strain and increase pilot performance and comfort and most of all improve flying safety.
