A taste sensor with lipid/polymer membranes was developed in this study for detecting sweet taste substances. The lipid membrane was modified with gallic acid (3,4,5-trihydroxybenzoic acid) to enhanced the sensitivity to sugars. The result from the absorption spectra obtained from UV spectrum measurements and potentiometric measurements with the taste sensor indicated that the pKa and the steric structure of the phenolic compounds play an important role for the potential change of the taste sensor on sugars.

In this study, we have developed a non-contact temperature sensor using a silver halide optical fiber for medical endoscopic usage. We have measured an infrared radiation which is transferred by a silver halide optical fiber from a heat source using a thermal optical power-meter and a thermopile sensor. To increase the amount of infrared radiation through the silver halide optical fiber and to the infrared sensors, optical devices such as an infrared collimator and a focusing lens are used. The relationships between the temperatures of a heat source and the measured output signals are determined. The measurable temperature range of a fiber-optic temperature sensor is from 30 to 60degC. It is expected that a non-contact temperature sensor using an infrared optical fiber can be developed for medical and industrial usages based on the results of this study.

In this paper the problem of stabilizing a linear timeinvariant system with quantized feedback is addressed. We focus on systems with rectilinear quantization where only some of the outputs are quantized either by limited sensor precision or data rate constraints and the rest of the output is sent to the controller without quantization. We call these systems partly-quantized feedback systems. Aside from the rectilinear boxes that we know output resides in, we determine moving hyperplanes in output space such that exact value of output has to lie on these planes too. Using the intersection of rectilinear boxes and hyperplanes, we find the best estimate of output to be used in linear feedback controllers and hence we reduce the maximum quantization error and find a smaller invariant region around origin. A simulation of the proposed controller is also presented.

Structural steel changes its magnetic characteristics when pressure is applied to it. For developing a force sensor using structural steel, B-H characteristics and magnetostriction characteristics are very important factors. In this paper, an experimental force sensor was constructed. This sensor consists of sensor metal (SUS630, stainless steel, annealing), a foundation metal, and an exciting coil. The analysis of the force sensor revealed that as pressure stress increases, the coilpsilas inductance decreases. We propose in this paper that it is possible to develop a large rated load force sensor which utilizes changes in magnetic characteristics in spite of a small size.

The effectiveness of ECG monitors can be significantly impaired by motion artefact, which can cause misdiagnoses, lead to inappropriate treatment decisions, and trigger false alarms. However, it is difficult to separate the noise from bio-signal due to its frequency spectrum overlapping that of the ECG. In this paper, we developed a wireless multi-sensor device for physiological signal monitoring, without any constraint of the belt. The device is attached to the belly. The skin temperature, ambulatory ECG, and respiration can be measured at the same time and shown via PC. The designed and implemented portable ECG recorder using accelerometer based on motion artefact removal technique was demonstrated for tele-homecare or ambulatory ECG monitoring.

Model-based infrared (MBIR) reflectance spectrometry has been introduced for characterization of the depth and profile of deep trench structures in dynamic random access memory (DRAM). Modeling the complex trench structure as a multilayer optical film stack with effective medium approximation (EMA) allows the determination of both trench depth and width from Fourier-transfer infrared (FTIR) reflectance spectrum. In this paper an algorithm combining artificial neural networks (ANN) and Levenberg-Marquardt (LM) is proposed to extract the geometric parameters from the measured reflectance data. An initial estimate of the geometric parameters is obtained by the ANN, and then it is used as an input for the LM algorithm which converges to a final solution with a few iterations. The combined algorithm has been implemented on our own experimental platform, and it has been demonstrated to achieve very high accurate results as well as fast enough computation ability.

Distributed wireless sensor applications are useful for visualizing spatially and geographically related data such as location, neighborhood, weather, and measuring specific changes in the environment. Desires to augment these interfaces with additional specifications needed for distributed applications such as Power-Aware, Fault-tolerance and Processor agnostic deployment requirements have led to create a custom distributed Network Embedded Test-Bed that locally aggregate the measured signal from individual sensors and send it to a central coordinator for combined processing. We envision publishing and querying real-time (e.g. from sensors) over such distributed sensor farm applications which are deployed wirelessly and form a large sensor network. Existing solutions, although useful for writing the simple applications mentioned above, have several drawbacks in achieving this vision. First, publishing even a single stream of data as a useful service is a non-trivial task. Much useful data is not being stored yet because the need for managing a sensor farm has lots of complexities which make them unreliable in terms of polling time and communications costs. Second, existing applications are mutually incompatible and are processor centric and needs many ports which may introduce un-reliability. Third communication costs are not scalable to handle a sensor farm application and it does not provide an easy way to extend such a Network Embedded Test-Bed. The Network Embedded Test-Bed project aims to address these challenges, we like to model existing applications needs into a cross layer sensor network simulator called C-ERROR(Cross Layer Reusable Resource Optimized Routing) which allows different clustering algorithms to be integrated and measure its performance at each layer of the stack. To have a platform independent sensor OS and a scheduler which allows creating sensing tasks that have real-time constraints.

To efficiently manage the sensor networks the topology of the entire network has to be discovered by the monitoring node. In this paper a topology discovery algorithm for sensor networks has been described. The algorithm finds a set of distinguished nodes, using whose neighborhood information the approximate topology of the network is constructed. Only these distinguished nodes reply back to the topology discovery probes. These nodes logically organize the network in the form of clusters comprising nodes in their neighborhood. Topology discovery algorithms form a tree of clusters rooted at the monitoring node, which initiates the topology discovery process. This organization is used for efficient data dissemination and aggregation, duty cycle assignment and fault tolerance of the network system. The unpredictable behaviors of sensor networks have made it a vital point that how the operational nodes will be managed when a node in the network fails. In this paper fault tolerance mechanisms for sensor networks have been described for clustered response approach on considering different scenarios that may come to consideration when a node fails; thus ensuring maximum connectivity among operational nodes after the failure of the node. The mechanism explains how the information packets transmitted to the faulty node can be cached by an operational node. After being repaired the faulty node is reinstalled to operational state and the mechanisms of getting the repaired node connected to the network have been described in this paper. Reverse traverse mechanism has been described in this paper as a part of fault tolerance mechanisms, which ensures that the number of clusters is not increased when a faulty node is repaired and re-connected to the network. The mechanisms described in this paper are distributed and highly scalable.

In this article, copper germanate (CuGeO3) mixed noble metal pervoskite oxide was prepared by solid-state synthesis process first time. XRD confirms the orthorhombic pervoskite phase of material. Thick films of CG were prepared by screen-printing technique. The gas sensing performance of thick films were tested for various gases. It showed maximum sensitivity to H2S gas at 50degC for less than 10ppm gas concentration. The sensitivity, selectivity, response and recovery time of the sensor were measured and presented.
