In ubiquitous environments, sensor localization plays a critical role in various location-based systems. Commonly, sensor location is measured with Global Positioning System (GPS). Because GPS is not available in indoor environments, Received Signal Strength (RSS) of wireless sensors is used for indoor localization in place of GPS. However, there is a problem in measuring sensor location using ...

Wireless sensor networks (WSN) represent a new paradigm shift in Adhoc networks. Wireless Sensor Networks consists of small nodes with sensing, computation and communication capabilities. The sensor networks task is to sense the environment, and relay the information back to a remote base station, where the user can access it. Sensor nodes are deployed in a monitoring region to gather informati...

Wearable sensor systems which allow for remote or self-monitoring of health-related parameters are regarded as one means to alleviate the consequences of demographic change. This paper aims to summarize current research in wearable sensors as well as in sensor-enhanced health information systems. Wearable sensor technologies are already advanced in terms of their technical capabilities and are ...

Wireless sensor networks (WSN) are generally distributed independent sensors which work mutually to monitor all or some physical or ecological conditions, such as temperature sound, pressure, moisture, humidity etc. They are sometimes called as Wireless Sensors and Actuators Networks (WSAN) as well. Wireless Sensor Networks work thoughtfully to pass their information through the network by capa...

Tool condition monitoring systems (TCMS) have approached detection of tool wear over time from several perspectives: visual inspection, vibrational analysis, acoustic emission, power consumption and sound analysis. Current research focuses on monitoring methods involving expensive and complex sensor systems placed in close proximity to the machining operation itself. Understandably, industry ha...

This paper addresses an active structural acoustic control (ASAC) approach to reduce sound transmission through an aircraft trim panel. The focus is on the practical implementation of the virtual mechanical impedance approach through self-sensing actuation instead of using sensor-actuator pairs. The experimental setup includes two sensoriactuators designed from an electrodynamic inertial excite...

Simultaneous structural-control optimization of a coupled structural-acoustic enclosure is investigated in this paper. The whole system has a rectangular parallelepiped sound field of which the entire bottom face and the partial top face are covered with two elastic plates while the other boundaries are enclosed with rigid walls. Two point forces applied on the two plates are used as disturbanc...

The main objective of this work is to develop an electronic travel aid to assist the blinds for obstacle identification in their navigation. This navigation assistance for visually impaired (NAVI) system presented in this paper consists of a single board processing system (SBPS), a vision sensor mounted headgear and a pair of stereo earphones. The image environment in front of the blind is capt...

This chapter seeks to explore the development of an ambient intelligent dance space. In particular, the chapter proposes intelligent systems that use non-linear optimization as well as symbolic rule-based systems to adjust sound/music, on-stage lighting, and projected visual imagery in terms of movement and color to dynamically reflecting the dancer’s arousal state measured through physiologica...

We have designed and constructed a hardware test bed to explore the application of a dense, multi-modal, peerto-peer sensor network as an electronic ”skin”; a sensate lining that covers an object to sense, process, and coarsely classify local stimuli. Resulting parameters can be routed between nodes (which we term skin ”patches”) neighbor-to-neighbor to a portal for external analysis and/or pro...
