In contemporary times, communication systems have become the major drivers of globalization and trade facilitation. From its simple beginning to the more recent 5G and 6G technologies which are at various stages of development and applications, capable of entrenching the era of the Internet of Things (IoT), advancing Machine-to Machine (M-2-M) integration, and further revolutionizing the speed of seamless communication between smart devices. Significant advancements have also been achieved in the area of auxiliary technology interfaces incorporated into mobile communication systems such as the wireless LAN (Wi-Fi), Bluetooth, Infra-Red (IR), and sundry communication systems operating at the higher frequency bands of the electromagnetic spectrum. Against this backdrop, this work reviewed some communication systems highlighting their technology and developmental trends. Furthermore, it attempts to accurately forecast the probable direction of future advancements in communication systems, based on a painstaking trend and pattern analysis of the technological improvements of Bluetooth, Radar, and Wi-Fi technologies and some other communication systems in the past decade.

“…Fuzes as a key element in the chain of action of a weapon system to achieve effective damage to a target, despite the adoption of multiple security measures, its safety problems still occur. The complex and hostile environment [3,4] in which the fuze is stored, loaded, fired, flown and then acted upon by the target is one of the major causes of its failure. Conducting reliability enhancement tests based on environmental stimulation helps to analyze and predict how the environment affects the fuze, to identify typical defective failures of the fuze, which helps to improve the reliability of the fuze's functioning [5,6,7].…”

The current reliability enhanced test profiles are inefficient and costly, an integrated temperature and vibration reliability enhancement test profile design method based on multi-stress failure excitation simulation (MSS-RET) for typical ballistic devices is presented in this paper. First, the fault logic analysis is conducted by combining the product fault tree and product structural characteristics, and establishment of a integrated test profile design framework, to improve the determination of profile elements of the guidelines. using multi-stress finite element deterministic analysis joint failure physical model of the failure prediction method, obtain a vibration termination stress valuation, starting stress, and other profile elements, achieved the optimization of the test accuracy; Combined with relevant standards, clarify the temperature stabilization time. Through the principle of thermal stress generation, combined with finite element simulation data analysis, specify the vibration excitation loading time, optimize fault excitation intensity, improve the low efficiency and high cost of the reinforcement test. The MSS-RET is validated by taking the design of a comprehensive temperature and vibration test profile of a fuze detection module as an example, the results shows that the obtained test profile can reduce the test error by up to 44% compared with the traditional method.

The inadequate ventilation and complex environments in underground coal mines lead to a high concentration of dust particles. As a result, the health of the miners and the accuracy of laser rangefinder measurements are endangered. It is crucial to enhance the laser rangefinder’s efficiency to mitigate health risks and reduce labor intensity. In this study, we propose a laser power attenuation model and a ranging correction model to address the issues of laser power attenuation and inaccurate ranging in coal dust environments. The proposed models are based on theoretical analysis and practical experiments, and both are dependent on the dust particle size (<250 μm) and mass concentration. Firstly, we assessed the factors that caused laser power attenuation and demonstrated that our proposed model could accurately predict them (maximum residual of 0.06). Secondly, we obtained the connection between the attenuation coefficient and dust concentration by applying the Lambert–Beer law. Lastly, we established the ranging correction model by collecting laser wavelength information. The outcomes show that the root mean square error of the corrected values ranges between 0.27 and 0.47 mm. To summarize, our suggested model and correction technique can efficiently enhance the precision of laser rangefinder measurements, thus improving underground work in coal mines.
