This paper documents current investigations which are attempting to find a suitable audio pattern to identify the moment when a prosthetic hip-joint replacement has been correctly inserted into the thigh bone. Research Questions: We have two objectives: first is there any distinctive pattern of sound frequency or resonation associated with proper femoral rasping? Second: can we predict the point where fracture of the femur during the rasping process occurs using the analysis of the sound frequency changes? Initial research into this project has noted that by placing a bone conduction microphone close to the knee of the patient, the resonances of the thigh bone can be detected as the joint is reamed into place. A distinct increase in the pitch of the resonance can be noted as the joint reaches its correct position. It is proposed that by collecting and analysing a suitably large database of audio recordings of the rasping process, that a prediction model for when the joint is optimally reamed into position can be created. It must be noted that, as each femur will be of different size/density, each rasping process will yield different results. Therefore analysis will have to be undertaken to create a model which will prove reliable for all cases.

An optical fiver gas-phase biosensor (bio-sniffer) for assessment of indoor formaldehyde was fabricated and tested. The bio-sniffer measures formaldehyde vapor as fluorescence of reduced nicotinamide adenine dinucleotide (NADH), which is the product of formaldehyde dehydrogenase (FALDH) reaction. Usually, an enzyme loses its specific activity in the gas phase. This makes biochemical gas monitoring difficult. We used a micro flow-cell with a FALDH immobilized membrane to prevent the FALDH from deactivation. An ultraviolet light emitting diode (UV-LED) with peak emission of 335nm was employed as an excitation light source. Emission of the UV-LED was introduced to the optode through an optical fiber and fluorescence of NADH was picked up coaxially at the optode. In order to improve the sensitivity, a photomultiplier tube was utilized as a photodetector. Consequently, continuous formaldehyde monitoring with biochemical method was successfully conducted with high sensitivity and high selectivity. A real-sample test was also carried out with the bio-sniffer. According to the results, it is expected to be useful in fast and convenient monitoring of indoor formaldehyde.

In recent years, salient region detection techniques are widely used in image segmentation. The traditional image segmentation techniques primarily depend on human to label or mark the target areas interactively, which is far insufficient for real-time image processing. Therefore, in this paper we propose a new method of unsupervised saliency detection based segmentation, for high-resolution satellite images, which requires no manual interaction and prior knowledge of their content. Our proposed model of saliency at the considered pixel is a weighted average of dissimilarities between the pixel involved patch and the other patches. Moreover, we evaluated global and multi-scale contrast differences in order to extend the saliency calculation window to the entire image. To acquire an appropriate threshold for the remote sensing images segmentation, we apply a probabilistic a-contrario framework based on perception principle to measure the meaningfulness of such saliencies. According to the experimental results, our method is feasible and practicable for satellite image segmentation.

Aim of this paper is to demonstrate virus detection by dielectrophoretic impedance measurement (DEPIM). DEPIM consists of two processes of dielectrophoretic trapping of target particles and measuring impedance change with increasing the number of trapped particles. DEPIM has been used to detect bacteria suspended in aqueous solution. In this study, norovirus and rotavirus, which cause gastroenteritis in human, were used as the target viruses. As the results, 50 ng/ml of norovirus and 10 ng/ml of rotavirus were detected within 100 s.

Drowsy driving is a major cause of road accidents. This paper analyses the drivers' behavior in the state of fatigue driving and introduces the latest developments of drowsy driving detection technology. In this study we also propose a drowsy driving detection based on the driver's physiological signals such as eye activity measures, the inclination of the driver's head, sagging posture, heart beat rate, skin electric potential, and electroencephalographic (EEG) activities, as well as response characteristics, decline in gripping force on the steering wheel and lane keeping characteristics. By developing a hierarchical model that is able to collect the sensing data, analyze the driving behavior and the reactions to the driver, it can provide a safe and a comfortable driving environment. Combining different indications of drowsiness and processing the contextual information to predict whether a driver is drowsy, the system not only issues a warning for the driver, but also provides the drowsy driving information to transportation control center and other vehicles if necessary.

While interferometric fiber optic gyroscopes (IFOGs) are used in the inertial guidance area as replacements for traditional spinning rotor gyroscopes, the presence of optical noise as well as cost of such systems demonstrate that IFOGs still have not been optimized for this purpose. This paper proposes a solution to these problems, describing the design details and features of an optimized prototype attitude control system that uses depolarized IFOGs in the gyros and mounts depolarizers simultaneously on the entrance and exit of the fiber loop. Preliminary tests of an attitude control system built using these IFOGs demonstrate that this relatively low-cost system achieved the objective of compensating for the earth's spin and thus could be deployed as a system for the stabilization of telescopes.

There are growing demands for measuring surface and internal temperature profiles of rotating objects in the fields of engineering and manufacturing industries. In this work, a new noncontact method for measuring such temperature profiles of a heated rotating cylinder is presented. A laser-ultrasonic technique which provides noncontact ultrasonic measurements of heated objects is employed in the method. Surface temperature measurements for a heated cylinder using the laser-ultrasonic technique and a heat conduction analyses with a finite difference calculation are combined together for making a quantitative evaluation of the internal temperature profile in the radial direction of the cylinder. To demonstrate the feasibility of the combined method, an experiment with a heated steel cylinder (100 mm dia.) rotating at 300 min-1 is carried out. A pulsed laser generator and a laser Doppler vibrometer are used for generating and detecting surface acoustic waves (SAWs) on the steel cylinder, respectively. Measured SAWs are used for determining both surface and internal temperatures of the cylinder. As a result, the estimated temperature distributions during heating almost agree with those measured by an infrared radiation camera. In addition, the influence of the rotating speed of the cylinder on the error in ultrasonically estimated surface temperatures is examined.

Assessment of a muscular fatigue level and the grade of recovery from muscle fatigue are required at various scenes such as medical treatment, welfare, the work place, etc. Frequency transition of EMG is generally utilized for it though, it is impossible to apply it in case of isotonic contraction and also influenced by condition and environment. Thus there are no apparatus and method which measure fatigue noninvasively and simply. In this study, we propose to apply near-infrared spectroscopy (NIRS) which can measure the amount of oxygenated hemoglobin and deoxygenated one for fatigue estimation, and attempt to evaluate the level of local muscle fatigue.

Combining magnetic catalysis effect, surface plasmon resonance phenomena, and common-path heterodyne interferometry, a highly sensitive and highly stable carbon monoxide sensing technique was proposed in this paper. Magnetic catalysis material SnO2-Fe3O4 was prepared and was spin coated on the gold film of SPR prism. The SPR apparatus can provide a highly sensitive ability to carbon monoxide. Carbon monoxide gas at different concentrations was measured under different strengths of applied magnetic fields. The experimental results reveal that the system has a best resolution of 0.0507 ppm applied 24 Gauss magnetic field in normal direction. Due to the introduction of common-path heterodyne interferometer, the system is stable against environment vibrations.
