A low cost and compact sensor system for mobile measurements of combustion gases is described. The sensor utilizes optical absorptions in the UV-Vis range using LED-based spectroscopy. Combustion processes are currently one major cornerstone in the way we are using primary energy sources in our modern life. Harmful gases such as nitrogen oxides (NOx) and sulfur dioxide (SO2) as well as particles are emitted thereby in significant amounts if the processes, engines, catalysts and filters are not working properly. It is important to enable an easy to use and low cost monitoring of these harmful emissions: Applications are spot check emission control in transport, in industry, in harbor areas or mobile functionality control in operation of combustion devices and industrial gas filters. A cost effective mobile sensor is realized for the measurement of NO2 and SO2 in wide dynamic range from 0.1 ppm to a few 1000 ppm with high temporal dynamic (100 msec). Further an opacimeter measurement and a stray light sensor for particle detection are included. In addition temperature, humidity and pressure are measured. The presented sensor design is optimized for mobile airborne gas measurements. Its construction is adapted to a license free commercial 1400 g video drone. The sensor is simply clicked under the drone, while the drone functionalities (video, distance sensors etc.) are not influenced by the gas sensor. The sensors weight is about 300 g including its battery. The measurement data are recorded on SD-card and are send for online visualization via Bluetooth e.g. to a smartphone. The light weight, compact, robust and low power consuming battery powered sensor design can also be used in hand held devices. In addition the sensor can easily be modified for other gases such as for ozone (O3) detection.

In this paper, a capacitive sensor integrated with the Surface Acoustic Wave (SAW) sensor is used for liquid level measurement of a storage tank. The capacitive sensor is kept at the bottom of the tank, and the terminals of the capacitor are connected to the SAW sensor. The SAW sensor observes the change in capacitance. The variation in the liquid level of the tank is proportional to the phase shift in the interrogation unit. The proposed system is a hybrid type system which is capable of transmitting the measured information in the wireless domain, and the system does not require any onboard power-supply.

Bioimpedance spectroscopy consists in measuring the complex impedance of biological tissues over a large frequency domain. This method is convenient in particular for studying body composition, blood characterization and even cancer detection. This wide range of applications makes it suitable as a part of health monitoring systems. Today’s self-monitoring devices tend to be portable, wearable or even implantable. Next generation bioimpedance sensing systems thus require to be implemented with power and resource savings in mind.Impedance measurement methods are divided into two main categories. Some are based on “single-tone” signals while the others use “multi-tone” signals. First methods use a pure frequency sine wave to make the measurement. They benefit from a very simple analysis that may consist in synchronous demodulation. However, the operation must be repeated for each frequency over the domain of interest. Due to this necessary frequency sweep, the total measurement may take long. On the other hand, generating a multi-frequency signal allows the analysis to cover the whole frequency range simultaneously. This is at the cost of a more complex analysis algorithm (discrete cosine transform – DCT, typically). Unfortunately both methods result in excess power consumption: long time of measurement for single-tone frequency sweep, hardware and computational resources for multi-tone. That make both approaches hardly suitable for embedded applications.In this paper, we propose an intermediate approach that combines the speed of multi-tone systems with a much simpler analysis algorithm than DCT or FFT. Using specific properties of the bioimpedance, we even show that we can get rid of any multiplier. This results in a minimal implementation using only adders and synchronous ADC. For optimal performances, this small footprint digital processing can be easily synthesized and embedded on a mixed-mode ASIC together with the analog frontend.

Rotameter is a particular kind of flow meter, based on variable area principle. In this paper, an intelligent inductive pickup type flow transducer using rotameter is developed with temperature compensation. The float of rotameter is attached with a ferromagnetic wire and with the movement of float the self-inductance of inductive pickup changes. The self-inductance is changed into a voltage with the modified Maxwell bridge network. The density of the fluid flowing through the rotameter get changed with the change in temperature, and it disturbs the calibration of rotameter. In this paper, different ANN (Artifical neural network) algorithm scheme is used for compensating the temperature influence in the modified rotameter.

This paper presents fruit battery evaluation as a method to distinguish between oil palm fruit ripeness stages. The fruit battery method consists of two electrodes that have different ionization tendencies. The fruit battery can detect oil palm fruit electrolyte changes from decreasing moisture content as the oil palm ripens. This paper proposes a condition to distinguish oil palm ripeness by varying the depth and interval between electrodes. Subsequently, the probability of estimating oil palm fruit moisture content using this method is evaluated using a regression analysis.

This paper describes a method to estimate the differential detection for reducing laser noise in an electro-optic sensor system. This new estimation method evaluates the differential detection effect on noise reduction by using a phasor diagram and fast Fourier transform. The estimation results obtained from this method agree with the DC level dependence of the signal-to-noise ratio, thus confirming that the proposed estimation method is suitable for evaluating the effect of differential detection on noise reduction.

This paper presents a collaborative learning system to support the learning experience of children in museums. The proposed system uses the Kinect Sensor for human sensing tasks required for delivering an interactive learning experience. The study recognizes that museums are an important source of scientific knowledge as they facilitate experiential and conversational learning. However, the main learning method in museums is passive—observing exhibits and reading explanations on text panels. Thus, few opportunities exist for children to discuss the experience and engage in conversations, thereby limiting the learning experience for children. Therefore, we developed a Kinect sensor based collaborative immersive learning support system for a museum that enables children to learn through body movements and conversation. In addition, we developed interactive content that can be manipulated by children using body movements. In this manuscript, we describe the outline of the system under development. In addition, we demonstrate using experiments that the Kinect sensor can be applied to accurately recognize the body movement of multiple users; this can be regarded as the first step towards realizing a cooperative learning support system for museums.

We developed a motion-blur-free video camera for shooting non-blurred videos of unstable fast-moving objects by implementing an improved actuator-driven frame-by-frame intermittent tracking method on a high-speed vision platform and an external field-programmable gate array board. With our tracking method, the camera frame-timing is controlled so that the speed of the camera viewpoint coincides with the apparent speed of the target object during the camera exposure time. Our motion-blur-free video camera can shoot non-blurred 1024×1024 images of fast-moving objects at 750 fps until 7.5 m/s unidirectionally. Compared with the degradation in video recorded without tracking, our method reduces image degradation from motion blur 1/10 times or less without shortening the exposure time. Its performance was verified by the experimental results of several fast-moving objects using a high-speed conveyor belt system.

The developed synthesis process is scalable and compatible with IC technology. In order to enhance the sensitivity of the sensor, an on chip Ni (nickel) heater configuration was fabricated for heating the sensor platform. In order to reduce the power consumption, a diaphragm was created using standard Reactive Ion Etching (RIE).
