A statistical approach to the uncertainty reduction of a vibrating-wire system for the measurement of magnetic axes in accelerator magnets is presented. A surface response methodology is employed to relate metrological performance to system design parameters by means of a suitable model based on analysis of means. The model is identified by means of experiment design based on an orthogonal array and its significance is verified by analysis of variance. The impact of each design parameter on the metrological performance is assessed and useful indications are derived for future improvement. Validation experiments are carried out on a permanent quadrupole magnet for the Compact Linear Collider at the European Organization for Nuclear Research.

Physicians currently have no objective information about the intensity and quality of a Stroke patient's daily-life activities after returning home from the rehabilitation hospital. Therefore there is a need to unobtrusively monitor patients performing daily life tasks at home. Within the INTERACTION project, a new inertial based sensor suit was developed, which is able to measure Stroke patients at home. This research extend the INTERACTION project by developing an Arm Usage Coach (AUC), which stimulates the patients affected arm to be used more often at home. The results of a usability evaluation showed high scores in usability, but some design and wear ability problems were found. An open loop evaluation of Stroke patient data showed how different decision criteria parameters, for applying feedback to the patient, resulted in different outcomes of feedback given. Based on both evaluation results, a new prototype is in development, which will be evaluated by Stroke patients in clinic.

Ball nose milling is most commonly used in computer-controlled sculpture surface machining using computer numerical control (CNC) machines. Tool condition monitoring (TCM) for the ball nose milling by CNC machines will significantly improve machining efficiency, minimize inaccuracy, minimize machine down time, and maximize tool life utilization. Central to TCM is tool wear monitoring, and wear monitoring of ball nose milling poses new challenges compared with the conventional machining. This paper presents a model-based approach to estimate and track the tool wear profile along the cutting edge for ball nose milling based on the cutting force against it. The model-based approach uses a geometric model and a cutting force model to characterize the ball nose milling process and estimate the tool wear profile. The geometric model is used to determine the geometric features, such as the chip load along the cutting edge, and friction length for given tool path direction and the cutting parameters. The mechanistic cutting force model is developed using the chip load about the cutter rotation axis and the cutting coefficients. The chip load is derived from the geometric model, while the cutting coefficients are determined using the chip load and experimentally measured cutting force when machining on an inclined plane. To verify the proposed tool wear estimation models, experiments were conducted on a hemispherical work piece with different sequence of cutter path directions to simulate variable contact between the ball nose cutter and the work piece surface as encountered in sculptured machining. The tool wear profile was measured and compared with the estimated tool wear profiles from the models. Two variations of the model-based approaches are also compared with the proposed approach for tool wear profile estimation and the best and robust match has been observed for the proposed approach.

The escalating applications of miniaturized sensors have led the microelectronics industry to stay abreast with the precise micro-fabrication technologies. The following article describes a new technique for the fabrication of miniaturized interdigitated capacitive sensors that own highly sensitive and real-time detections capabilities. In standard lithographic procedure, the sensors are fabricated applying different photoresist materials that give rise to the variable characteristic profile of the fabricated product. Single crystal p-doped Silicon wafer was used as a substrate material due to its advantageous properties over Germanium. Heidelberg system was used for the maskless lithographic patterning of the new interdigital sensors on a silicon substrate. The process was carried out in a clean room in the absence of ultraviolet light at a fixed temperature. The fabricated sensors were used for inflammable gas sensing application. Electrochemical Impedance Spectroscopy was applied to read the resistive and capacitive impedance measured by the sensor. The results proclaimed that the fabricated sensors own better performance in LPG detection as compared to its commercial counterparts.

The concept of magnetic sonification device is presented. Although magnetic fields could be used for a reusable energy source, it could not be noticed by human's sense. In order to notice the existence of magnetic field as a power source, this paper presents a magnetic sonification device in low cost. This device consists of a pickup coil and conventional FM transmitter. The possibility of this operation without any battery is also considered.

Real time, high resolution measurements of gas concentrations are a task in many industrial applications like smoke detectors, medical and analytical devices. By usage of LED sources for optical absorption spectroscopy, such systems have a high potential to replace commonly used electrochemical sensors, even in low-cost applications. Depending on the gases, they can provide higher sensitivity, selectivity and dynamical response. Background of this paper is the optical gas concentration measurement by usage of LEDs, which are matching the specific absorption lines of different gases. The paper describes in detail a laboratory device, developed for high precision, multispectral (up to 8 wavelengths), referenced (20-bit, two-channel simultaneous sampling) measurement system with temperature stabilized LED sources. While the described system was developed for laboratory purposes with high precision and flexibility in mind, the key components (ADC/LED-Driver) are very low-cost and the system could also be driven by a simple microcontroller.

Standalone inertial navigation system (INS) in indoor pedestrian positioning is becoming imminent as the researchers exploit its small form factor and low power requirement. This will result in small-size, low-power wearable devices that are not obtrusive to the users and yet provide sufficiently accurate pedestrian localization and tracking within. At this stage, most of the recent INS-based indoor pedestrian positioning systems still have to interface with other computing machines such as a laptop or smartphone to perform computationally demanding algorithms. Most of the existing techniques operate in off-line and not real-time mode. In this paper, we propose a real-time indoor pedestrian dead-reckoning system based on embedded INS. The results show that our system successfully track the distance travelled by pedestrians up to an error of three percent with a position update interval less than a second.

Inline total inspection of the laser welding joint of ultra-fine suction stainless steel pipes for medical apparatus is very important. An electromagnetic defect detector for laser welding joint on stainless steel pipe was proposed. The electromagnetic defect detector consists of a figure-eight detection coil and an exciting coil. The stainless steel pipe with laser welding joint (i.e. “acceptance”) is fixed in a coil of the figure-eight coil. And the pipes of inspection target are passed through another coil. When the “acceptance” is passed through the coil, the output voltage e8 in the figure-eight coil equals zero. It is judged as an acceptance certainly. On the other hand, when a stainless steel pipe excluding the welding joint or the pipe with a defect (i.e. “reject”) are passed through the Coil 2, e8 ≠ 0 is obtained. The authors fabricated and evaluated the electromagnetic defect detector. The detector was able to determine the acceptance of the reject at the laser welding joints on stainless steel pipe.

Zinc and Tin Oxide nanowires were synthetized by vapor-phase growth on alumina substrates, in order to fabricate conductometric chemical sensing devices. Materials were morphologically characterized by FE-SEM, and structurally by mean of XRD and Raman spectroscopy, confirming the crystallinity of both materials. These devices were then mounted inside an electronic nose and their performances were evaluated in real measurements towards a specific matrix composed by Parmigiano Reggiano, a famous Italian cheese. The two materials behave very differently in presence of the target compound.

In order to increase the versatility of multi-fingered humanoid robot hands, we designed a human-finger-sized three-axis tactile sensor using a simple structure. Since we adopted a feeler-less structure for miniaturization, we acquired the three-axis tactile data via image data processing. With this sensor design, we solved the intrinsic problem of the ordinal three-axis tactile sensor's insensible zone. In a series of verification experiments, the sensor measured variation in normal force in the range of 0 to 2.5 N; furthermore, it detected variation in tangential force in the range of 0 to 0.25 N under 1.5-N normal force.
