A liquid crystal display (LCD) recycling process is needed to increase its efficiency by recovering the resources in addition to metals and plastics. This study investigates the pre-treatment process for recycling LCD glass. Recycling pre-treatment includes dismantling the LCD from the waste product, crushing the glass, and separating the glass particles from the impurities. Scanning electron microscopy confirmed that the oscillation milling process is more effective in maintaining uniform powder shape and size as compared to the cut milling process. The glass particles crushed by the oscillating mill, optimized at 1500 rpm, had a uniformly distributed particle size of less than 10 µm. These small particles were separated from the organic impurities, achieving a 98% pure powder that can be used as recycled raw materials. The proposed pre-treatment process for recycling LCD glass will enhance the ability to use waste glass as a valuable resource in the manufacturing of future displays.
This paper presents a relationship between Auditory Display (AD) and the domains of music and acoustics. First, some basic notions of the Auditory Display area are shortly outlined. Then, the research trends and system solutions within the fields of music technology, music information retrieval and music recommendation and acoustics that are within the scope of AD are discussed. Finally, an example of AD solution based on gaze tracking that may facilitate music annotation process is shown. The paper concludes with a few remarks about directions for further research in the domains discussed.
In this paper we propose a method which allows to overcome the basic functional problems in holographic displays with naked eye observation caused by delivering too small images visible in narrow viewing angles. The solution is based on combining the spatiotemporal multiplexing method with a 4f optical system. It enables to increase an aperture of a holographic display and extend the angular visual field of view. The applicability of the modified display is evidenced by Wigner distribution analysis of holographic imaging with spatiotemporal multiplexing method and by the experiments performed at the display demonstrator.
This paper presents the results of Pilot Assisting Module research performed on two light aircraft flight simulators developed in parallel at Brno University of Technology, Czech Republic, and Rzeszow University of Technology, Poland. The first simulator was designed as an open platform for the verification and validation of the advanced pilot/aircraft interface systems and inherited its appearance from the cockpit section of the Evektor SportStar. The second flight simulator, the XM-15, has been built around the cockpit of a unique agriculture jet Belfegor. It introduced a system architecture that supports scientific simulations of various aircraft types and configurations, making it suitable for conceptual testing of Pilot Assisting Module. The XM-15 was initially designed to support research on advanced flight control systems, but due to its continuing modernization it evolved into a hardware-in-the-loop test-bed for electromechanical actuators and autopilot CAN based controller blocks. Pilot-in-the-loop experiments of proposed Pilot Assisting Module revealed favorable operational scenarios, under which the proposed system reduces the cockpit workload during single pilot operations.
