Geothermal energy can make an important contribution to the U.S. energy portfolio. Production areas require seismic monitoring tools to develop and monitor production capability. This paper describes modifications made to a prototypical seismic tool to implement improvements that were identified during previous tool applications. These modifications included changing the motor required for mechanical coupling the tool to a bore-hole wall. Additionally, development of a closed-loop process control utilized feedback from the contact force between the coupling arm and bore-hole wall. Employing a feedback circuit automates the tool deployment/anchoring process and reduces reliance on the operator at the surface. The tool components were tested under high temperatures and an integrated system tool test demonstrated successful tool operations. / Master of Science

This monitoring system includes the development of low sensors that can monitor the temperature of non-destructively, i.e. without the need to reform the building. Deals with the analysis of the use of wireless transmission networks with the IEEE 802.11 standard and the IEEE 802.15.4 standard, as a possible solution for temperature monitoring in buildings using wireless networks. Discusses the development of a technological application capable of performing the monitoring of the air temperature and surface buildings using standard wireless networks IEEE 802.15.4. It also presents a solution for temperature monitoring in intelligent buildings, using the IEEE 802.11 standard. / O presente trabalho apresenta, o desenvolvimento de um sistema para o monitoramento da temperatura de superf?cie e da temperatura do ar em edifica??es no meio urbano, utilizando transmiss?o de dados sem fio com os padr?es IEEE 802.11 e IEEE 802.15.4.
