This proposed pump comprises of simple elements such as a tube and a Non-Return Valve (NRV) as a down-hole component connected to a length of the tubing, and a piezoelectric actuator. The operating principle is based on the inertia of water column within the riser tubing. The water is drawn from the container through NRV and it increases the liquid column head in the tubing by rapid up and down movements. The piezoelectric actuator produces this movement by vibrating the cantilever beam in resonant frequency with the tube mounted on its tip. The closed loop electronic circuit is connected to maintain the vibration at resonant frequency, so that the pump can discharge the water at regular intervals of time. This simple pumping mechanism and the advantages of piezoelectric actuator such as lower noise generation and ease of miniaturization make this pump suitable for some important applications in biomedical engineering and electronics cooling systems in military applications. The characteristics of the proposed pump are measured and verified with simulated results.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126609300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

THz technologies are expanding into much broader applications in recent years. Due to the vast available multiple gigahertz (GHz) broad bandwidths, THz radios offer the possibility for wireless transmission of high data rates. Multi-Gigabits per second (MGbps) broadband wireless access based on THz waves are closer to reality. The THz signal high atmosphere attenuation could significantly decrease the communication ranges and transmittable data rates for the ground systems. Contrary to the THz applications on the ground, the space applications in the atmosphere free environment do not suffer the atmosphere attenuation. The manufacturing technologies for the THz electronic components are advancing and maturing. There is great potential for the NASA future high data wireless applications in environments with difficult cabling and size/weight constraints. In this study, the THz wireless systems for potential space applications were investigated. The applicability of THz systems for space applications was analyzed. The link analysis indicates that MGbps data rates are achievable with compact sized high gain antennas.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116410022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anti-icing systems in dated aircraft predominantly apply hot engine bleed air to regulate the temperature on the aircraft control surfaces. The Royal New Zealand Air force (RNZAF) P-3K Orion aircraft utilizes a manually activated control system for controlling and monitoring the leading edge anti icing requirements. This manually activated system is becoming unreliable and difficult to maintain, the aircrew are required to manually activate the control circuit and in some instances constant monitoring is required. This paper discusses an automated solution that applies a fuzzy logic control circuit to control flow control valves which in turn regulate the amount of bleed air passed through a wing cavity. The control for the system is provided by a mixed-signal field programmable microcontroller, the Silicon Laboratories C8051F020. Automatic regulation of the bleed air flow provides temperature stability at the required set point. This solution reduces the aircrew interaction, achieves efficient control of the engine bleed air, and provides additional data to the user.","PeriodicalId":309610,"journal":{"name":"2013 IEEE Sensors Applications Symposium Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116049848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
