Farming is a major industry in New Zealand and the welfare of the farmed animals should be of high importance. A system is required to estimate the pain felt by animals in various procedures such as docking and castration. To do this the system will be used in research to identify the applied force levels which cause pain. It can also be used to estimate the effectiveness of pain control drugs for animals and establish required doses. This paper presents a new pain sensing system based on the use of stepping motor for applying force and flexiforce sensor for measuring the applied force. The new sensing system is successfully built and tested.

In this present investigation nanocrystalline TiO2 based sensor was developed for low ppm level (10-100) acetone detection. TiO2 thin film (Thickness: 1 μm) was prepared by solgel technique and deposited on the p-Si substrate (5 Ωcm, (100)) by dip coating method. Film was annealed at 450°C for 3 hours in air environment. XRD and FESEM study confirmed the (101) anatase growth with ~6-9 nm particle size. Pd electrode was deposited on the TiO2 sensing layer to prepare the Pd/TiO2/p-Si Metal-Insulator-Semiconductor (MIS) device structure. A detailed acetone sensor study was performed for this MIS device in the temperature range of 100 to 200°C. Sensor showed a repeatable sensing performance with a appreciably fast response time of 7.7 s at 100°C towards 10 ppm acetone with corresponding recovery time of 13 s at 200°C in 10 ppm acetone. Response magnitude was increased from 3.2% to 6.4% with increasing the acetone concentration from 10 to 100 ppm at 200°C.

Wireless Sensor Networks (WSNs) can experience problems (anomalies) during deployment, due to dynamic environmental factors or node hardware and software failures. These anomalies demand reliable detection strategies for supporting long term and/or large scale WSN deployments. Several strategies have been proposed for detecting specific WSN anomaly, yet there is still a need for more comprehensive anomaly detection strategies that jointly address network and node level anomalies. Intellectus methodology [23], [24], [25] build a tool that detected a new limited set of faults: sensor nodes may dynamically fail, be isolate and reboot and local topology control. These bugs are difficult to diagnose because the only externally visible characteristic is that no data is seen at the sink, from one or more nodes. This paper evaluate Intellectus methodology by different experiment in a Testbed network. In fact, Intellectus is be able to detect the injected fault and assess different scenarios of topology change.

A facile method for in-situ dressing of multi-walled carbon nanotubes (MWNTs) with TiO2 nanoparticles was achieved using modified microwave technique. TiO2/MWCNT nanocatalyst was formed using titanium (IV) isopropoxide as the precursor in the presence of MWCNTs and constantly irradiated for 5 min. FE-SEM micrographs suggested that TiO2 nanoparticles were well attached on the outer sidewall of MWCNTs. XRD measurement revealed that the TiO2 exist in anatase form with the calculated crystallite size of approximately 5 nm. XPS results show that TiO2 contacts closely with MWCNTs via Ti-O-C bonds. The photocatalytic activity of the nanocomposite was evaluated based the degradation of methylene blue under visible light irradiation. The results showed that 1 mg of TiO2/MWCNTs hybrid nanocatalyst efficiently degraded the dye.

Wireless power transfer offers the potential to redefine the usage of electricity. The advancement of near field magnetic resonance technology makes wireless power transfer viable nowadays. Measurement of power, however, remains an inherent challenge that derives from the difficulty of measuring the voltage and current of a battery. This paper presents our current development of wireless power transfer technology and focuses on the power measurement aspect of such technology. The continuous nature of the wireless power transfer is employed to provide accurate measurement of power, decoupled from the inherent problem of battery measurement. We have applied this technology in a model for the future transportation application.

In this paper, a novel approach for the detection of parcel loading positions on a pallet is presented. This approach realizes a substantial change in comparison to traditional system design of contour detection in de-palletizing processes. Complex 3D-vision systems, costly laser scanners or throughput decreasing local sensor solutions integrated in grippers are substituted by a low-cost Photonic Mixing Device (PMD) camera. By combining PMD technology and a predetermined model of loading situations, stored during the assembly of the pallet, this approach can compensate for the drawbacks of each respective system. An essential part of the approach are computer-graphics methods specific to the given problem to both detect the deviation between the nominal and the actual loading position and if necessary an automated correction of the packaging scheme. From an economic point of view this approach can decrease the costs of mandatory contour checking in automated de-palletizing processes.

Shrapnel injury is a major cause of death in victims of bomb blast, land mines and gun fire. In this paper, a Giant Magneto Resistance (GMR) sensor based online surgical tool that helps to remove metal shrapnel from victim's body is presented. This tool is intended to guide the surgeon to the exact location of the shrapnel during surgery. Presently doctors rely on imaging systems to locate them before surgery. Effectiveness of surgery solely depends on the doctors' skill to trace them, as these images do not provide real-time information of the location of the shrapnel during surgery. Therefore, in some cases, the shrapnel, in spite of being visible in the images, may become untraceable during surgery. So in such cases, a sensing tool that can guide the doctor to the location of the shrapnel will be very effective. An inductive proximity sensor can serve this purpose, but its output can be affected by its lead inductance or other parasitic circuit parameters. Therefore in order to overcome such effects, a GMR based sensing tool is proposed here. The details and experimental results obtained from this tool are presented in this paper. The tool can detect both ferromagnetic and paramagnetic metal targets.

Recently, the 3D sensing technique using multiple cameras has been applied to various areas such as visualization, motion capturing, and so on. However, improvement of the camera model calibration is indispensible for more precise measurement. In this study, we propose a practicable fuzzy modeling approach for 3D sensing utilizing the configuration of the stereo vision. A distance between a sensing target and the camera is used for structuring the fuzzy model for cameras considering optical projection characteristics. In our approach, the weighted least mean square error method is successfully applied considering fuzzy partition to formulate the fuzzy model. Then iterative calculations for solving the inverse problem of the camera fuzzy model are performed to attain measured coordinates. Through sensing experiments of stereo vision measurement based on the proposed approach, we showed the performance of the model was drastically improved compared with the conventional modeling approach.

This paper presents an airborne multi-spectral imaging sensor which is able to simultaneously capture three visible and three near infrared channels. The first prototype was integrated in a Schiebel CAMCOPTER® S-100 VTOL (Vertical Take-Off and Landing) UAV (Unmanned Aerial Vehicle) for inflight tests. A low cost version of the initial multi-spectral imaging system was developed to fit into a more compact UAV. The imaging system captures six bands with a minimal spatial resolution of approx. 10cm × 10cm (depending on altitude). Results indicate that the system is able to resist the high vibration level during flight and that the actively stabilized camera gimbal compensates for rapid roll/tilt movements of the UAV. After image registration the acquired images are stitched together for land cover mapping and flight path validation. Moreover the system is able to distinguish between different types of vegetation and soil.

Safety and driver comfort are the essential goals of new trends in automobile industry. An automatic wiper controller, helps not only in increasing safety by reducing distractions but also increases the overall comfort. Such an automatic control is available however it has limitations of high cost and low efficiency. In this work, we have proposed an automatic wiper controller, based on resistive rain sensor which is cost effective, efficient and has a wide range of output. An equivalent electrical and mathematical model of the sensor is developed, simulated and practically verified. The rain sensor has a predetermined geometry. Hence the rain water forms a film on the sensor surface causing its resistance to change non-linearly. To increase the overall efficiency of system, it is necessary to linearize the sensor response. It is achieved using electrical equivalent model of the sensor and with appropriate linearization circuit. Further, a customized embedded system is developed using PIC micro-controller to achieve motor speed variation based on sensor output. The proposed system is rigorously tested on a small segment car (Indica V2) for its performance. It is observed that, the developed system works satisfactorily under various rain scenarios.
