In this paper, a real-time monitoring system of all-weather fatigue driving which is based on DSP (TMS320DM643) is introduced. The method of regional area combining the skin color model, can quickly locate the drivers face. The paper also presents the judgment of eye state, the fetch of fatigue parameters (PERCLOS, ECT and EBF), and the general method for the determination of fatigue degree. The system has very strong using value, and practical significance.

Purpose – This paper aims to discuss the general principles behind the microwave sensing and demonstrates the potential of cavity microwave resonator device in real-time monitoring for: environmental monitoring with the focus on wastewater pollution, a system for oil/gas/water content evaluation in a dynamic pipeline, a system for real-time determination of bacteria concentration and a method for non-invasive glucose determination. Design/methodology/approach – Microwave sensing is a rapidly developing technology which has been successfully used for various industrial applications including water level measurements, material moisture content, in construction industry for non-invasive evaluation of structures and even in the healthcare industry for non-invasive real-time monitoring of glucose in diabetic patients. Novel microwave cavities designed and tested for specific applications are presented. Findings – The paper provides experimental results of testing the novel microwave sensing systems in a range of industrial and healthcare applications and discusses the potential of these systems for real-time monitoring of processes and parameters. Research limitations/implications – The concept of real-time microwave sensing was successfully tested, but further experiments are required to account for possible interference mechanisms before it can be used commercially on a large-scale. Practical implications – It is suggested that a novel approach to wastewater monitoring, namely using specially designed microwave cavity sensors, could lead to a successful development of an advanced platform capable of providing for a real-time detection of water content with superior sensitivity. Also, a system for real-time multiphase fluid composition monitoring is reported, which is essential for sustainable oil industry operation. Originality/value – The paper illustrated the potential of microwave sensing as a real-time monitoring platform for a broad spectrum of commercial applications, with a focus on system developed by the authors, namely, for the monitoring of a multiphase fluid flow in a dynamic oil pipeline, for real-time monitoring of nutrients concentration in wastewater and for healthcare industry, in particular for real-time non-invasive determination of the glucose levels and bacteria concentration.

A cataluminescence (CTL)-based gas sensor utilizing nano-sized Mn1.5Zr2O7 as the sensing material for the determination of hydrogen sulfide in air was proposed. The gas sensor showed high selectivity for hydrogen sulfide at 450 nm and satisfying activity at 320°C. The linear range of the CTL intensity versus concentration of hydrogen sulfide was 2~95 mg/m3, and the detection limit (3σ) was 1.5 mg/m3. No interference was observed while the foreign substances, such as formaldehyde, ammonia, ethanol, benzene, carbon monoxide and sulfur dioxide, were passing through the sensor. The gas sensor displayed good stability for continuously introducing hydrogen sulfide over 60 h, and allowed real-time monitoring of hydrogen sulfide in air.

A highly sensitive, simple and selective gas sensor was developed for the determination of trace acetaldehyde in air based on cataluminescence (CTL) on nano-sized Al2Ti2O7. The gas sensor showed high selectivity for acetaldehyde at 515 nm and satisfying activity at 295°C. The linear range of the CTL intensity versus concentration of acetaldehyde was 1~65 mg/m3, and the detection limit (3σ) was 0.5 mg/m3. No interference was observed while the foreign substances, such as ammonia, ethanol, formaldehyde, benzene, carbon monoxide and sulfur dioxide, were passing through the sensor. The gas sensor displayed good stability for continuously introducing 10 mg/m3 acetaldehyde over 60 h, and allowed real-time monitoring of acetaldehyde in air.
