Abstract: This paper presents the design and implementation of an object tracking manipulator robot coupled with an infrared sensor array. The robot is intended to demonstrate efficient object tracking within three-dimensional Cartesian space. The robot employs inverse kinematics to convert sensor inputs from Cartesian coordinates into a set of angular values which will drive the actuators based on the real-time location of the object being tracked. A series of experiments intended to assess the robot’s performance in terms of its angle accuracy, coordinate accuracy, and time accuracy in tracking an object was performed. Results indicates high performance tracking accuracy with total average angle accuracy exceeding , average coordinate accuracy above , and time accuracy around . The finding demonstrates the potential integration of an efficient object tracking system with inverse kinematics for more enhanced manipulator robot in wider applications.

Abstract: A novel transducer for megasonic cleaning of photomasks presents an approach that differs from previous configurations, and appears to have unique features for cleaning while minimizing damage. As the cleaning and damage processes are determined by the presence of cavitation, a thorough acoustic analysis was performed on the device, by using a calibrated hydrophone scanned at the photomask location, and a quartz photomask with embedded sensors.

Abstract: Operation of the corresponding large machine is not allowed during the regular NDT period. Therefore, reducing the test period and extending the test frequency, i.e., lowering the machine stoppage time due to an inspection is a very important technique for efficient energy usage. For this reason, IT-based real-time non-destructive testing (IT-NDT) technology has been being developed. This presentation reports on a magnetic camera, which is one IT-NDT technology, including the up-to-date experiences.

Abstract: Smell-Seeing Sensor Array consists of two parts. One concerns a sensitive arrays, and the other deals with image collecting and processing technologies. In this paper, a 2×2 sensor array is made by the metalloporphyrin (CuTPP、ZnTPP、NiTPP) and zinc phthalocyanine (ZnPC). Exposed in vapor of 14 different kinds of VOCs (Volatile Organic Compounds) at room temperature, the array appears color change. ARM-Linux system and OpenCV are used to collect and process the color change. This system could detect 14 kinds of VOCs, achieving visualization of gas sensor detection, and laying a foundation of further qualitative identification of VOCs.

Abstract: An Ionic Polymer-Metal Composite (abbr. IPMC) is a type of a smart materialconsisting of two layers of noble metal and an ion-conducting layer between them. Smart ma-terials are generally capable of actuating and sensing. Mechanical deformation of the IPMCbeam produces an electric potential di erence (in the order of mV) proportional to the tipdisplacement on the electrodes. In this paper, the sensing capabilities of IPMC samples will beinvestigated. The composites are manufactured in a form of a thin (0.3 mm) plate, which arecut into rectangular samples. Tests will be performed on separate samples and two electricallyconnected samples. Response to various frequencies will be tested for each sample and for twomechanically and electrically coupled samples, creating a simple sensor array.

Abstract: The aim of paper is to develop analytical mathematical models that describe the thermo dynamical equilibrium of resistive chemical sensor arrays /mixture of vapors multi-system. By using the Gibbs Duhem formalism, state equations in differential form, that the variations of intensive quantities (e.g. sensors partial sensitivity) as function of the gas mixture components concentrations and sensor array parameters describe, have been developed. Moreover, the responses of the sensor arrays as function of gas mixture components concentrations were modeled.

Abstract: The problem of air quality control is relevant at the present time. There are a lot of different devices and methods of air monitoring. The promising devices for air monitoring are automated air monitoring systems functioning in real time regime. The basic part of such system is a chemical gas sensor. Gas sensors can be combined into the arrays or so called multisensor systems to increase their effectiveness. Sensor arrays using semiconductor sensors based on SnO_xZrO_y thin films have been investigated in this work. The recognition of ammonia, nitrogen dioxide has been made.

Abstract: In this paper, an air quality monitoring system based on sensor array and framework of cloud computing is implemented. This system can surveil and report the information gathered from the ambient air condition in real time and inexpensive way, it can protect the public's right to know about the environmental security that everyone living in. All efforts and works of this paper is to turn the dreams into reality: to preserve and improve the quality of our living environment's air, in the sense of keep the damage to our health far away, through the strong pressure of public opinion.

Abstract: Electronic tongue is a new type of modern analytical instrumentation based on the human taste receptor research mechanism. Use the sensor array, as the biological sensing taste buds cells, to detect object,and to get results by the method of pattern recognition. Introduce the principles of electronic tongue, the study of several typical systems. Focus on the application in liquor quality, microbial detection, as well as some existing problems in the research development.

Abstract: With development of the short time interval measurement technology, array direction-finding technique for burst point localization has been applied to the actual. In this paper we conduct in the following order: the basic positioning principle will be elaborated at first. Then the precision estimation formula of the positioning will be deduced. Finally we perform the simulation experiment. The simulation results show that, if you want to improve the burst positioning accuracy, you need to decrease the measurement error of single station, and choose reasonable arrangement mode and the appropriate baseline length as far as possible.
