“…A brief review of the state-of-the-art ultrasonic sensor with wave propagation, atmospheric attenuation, sound wave reflection, and target tracking, along with market penetration of ultrasonic sensors, is presented in [ 135 ]. Most of the studies on ultrasonic sensor performance are presented in [ 136 , 137 , 138 , 139 , 140 , 141 , 142 , 143 , 144 , 145 , 146 , 147 ], which focus on the ability of sound waves to detect, reflect, and track the target. Besides, sound wave propagation in the presence of changing winds and temperatures, as well as several new designs to enhance resolution, have been introduced.…”

“…However, the results of all experiments show that good resolution is achieved within a shorter timeframe and the target wave reflection is accurate and reliable. The authors of [ 136 , 137 , 138 , 139 , 140 , 141 , 142 , 143 , 144 , 145 , 146 , 147 ], suggest the use of ultrasonic sensors for near-field perception based on their experimental studies.…”

Perception is a vital part of driving. Every year, the loss in visibility due to snow, fog, and rain causes serious accidents worldwide. Therefore, it is important to be aware of the impact of weather conditions on perception performance while driving on highways and urban traffic in all weather conditions. The goal of this paper is to provide a survey of sensing technologies used to detect the surrounding environment and obstacles during driving maneuvers in different weather conditions. Firstly, some important historical milestones are presented. Secondly, the state-of-the-art automated driving applications (adaptive cruise control, pedestrian collision avoidance, etc.) are introduced with a focus on all-weather activity. Thirdly, the most involved sensor technologies (radar, lidar, ultrasonic, camera, and far-infrared) employed by automated driving applications are studied. Furthermore, the difference between the current and expected states of performance is determined by the use of spider charts. As a result, a fusion perspective is proposed that can fill gaps and increase the robustness of the perception system.

“…One method for level sensing is using time domain reflectometry or microwaves [7]- [12], but this is a very complex approach that requires high-end costly hardware. Other typical level sensing methods are floating, ultrasonic or radar and hydrostatic [13]- [14]. These methods have proven to be reliable for industry sensing or automotive applications but cannot be applied to aerospace because of EMI (Electromagnetic interferences) phenomena or vibrations.…”

Capacitive Level Sensors (CLSs) are one of the most used level-sensing technologies in the industry as they are cheap, reliable and show high sensitivity. A typical capacitive level sensor with concentric and closed cylindrical armatures has slow dynamical response when used for high viscosity liquids such as lubricating oil for aeronautic applications. This work investigates a conditioning circuit that uses a capacitance to frequency converter and that could provide fast and accurate measurements when paired with cylindrical sensor using an LC tank-based oscillator as the exciting source. The preliminary experimental results show a linear response with small error and standard deviation.
