Wireless Sensing for the Built Environment: Enabling Innovation Towards Greener, Healthier Homes

Gaura E., Brusey J., Wilkins R., Cogent Computing Applied Research Centre, UK

The industry’s perception of wireless embedded networked sensing systems is changing towards a view of them as reliable, available, usable and affordable instruments. To many, they are no longer the next wave in engineering and [...]

Inferring Knowledge from Building Monitoring Systems: the Case for Wireless Sensing in Residential Buildings

Gaura E., Brusey J., Wilkins R., Cogent Computing Applied Research Centre, UK

Following more than a decade of intensive research work, Wireless Sensor Networks (WSNs) are commonly acknowledged today as proven research instruments for several application domains. In particular, they have made notable contributions to the understanding [...]

Wireless Sensor Networks for Aerospace Applications- Thermal Monitoring for a Gas Turbine Engine

Goldsmith D., Gaura E., Brusey J., Shuttleworth J., Cogent Computing Applied Research Centre, Coventry University, UK

The paper here reports on the development of a prototype wireless sensor network for thermal monitoring of aircraft gas turbine engines. The prototype acts as a concept demonstrator for the application at hand. Building upon [...]

Smart, Intelligent and Cogent Microsensors – Intelligence for Sensors and Sensors for Intelligence

Gaura E., Newman R.M., Coventry University, UK

The paper develops a terminology to describe sensors which have been enhanced in some way by the integration of some additional processing circuitry. Several terms, current in the literature, including 'smart sensors' and 'intelligent sensors' [...]

Microsensors, Arrays and Automatic Diagnosis of Sensor Faults

Gaura E., Newman R.M., Coventry University, UK

As man-made dynamical systems become increasingly complex, there is an ever-present need to ensure their safe and reliable operation [1]. These requirements extend beyond the normally accepted safety-critical systems (e.g. nuclear reactors, chemical plants, and [...]

Noise Considerations for Closed Loop Digital Accelerometers

Gaura E., Kraft M., Coventry University, UK

This paper investigates the noise shaping properties of a sigma-delta modulator type control system applied to a micromachined accelerometer. Three noise sources are present in such an electromechanical closed loop system: mechanical noise due to [...]

Comparison of Two Novel Control Strategies for a Closed Loop Micromachined Tunnelling Accelerometer

Gaura E., Kraft M., Coventry University, UK

This paper presents system level modelling and simulations results of two closed loop, force-feedback control strategies for micromachined tunnelling accelerometers. The first approach is based on the incorporation of the sensing element in a sigma-delta [...]
