    This paper examines the task of displaying more information about the environment using a conventional ranging sonar than is available in standard time-of-flight (TOF) maps. A conventional ranging sonar forms an environmental image that displays the information in the echo envelope, similar to a medical ultrasound image. The sonar performs rotational sector scans of simple objects and two complex ... View full abstract»

    Typical gas ionization sensors (GISs) work by fingerprinting the ionization breakdown voltages of the gases to be identified. In this work, we developed a GIS that operates by field-ionizing the unknown gas at exceptionally low voltages. The resultant field-ion current-voltage (I-V) characteristic was then used to identify the gas. Freestanding gold nanowires (AuNW), terminated with nanoscale whis... View full abstract»

    This paper addresses the optimization of prism-coupled, wavelength-interrogated surface-plasmon resonance (SPR) sensors. Limit of detection (LOD), rather than sensitivity, is chosen as a figure of merit. The Cramer-Rao bound (CRB) for spectral shift estimation allows lower bounds to be placed on LOD independent of interrogation system and estimation algorithm. Analytic evaluation of the CRB for a ...

    Micromachined silicon substrates have significantly reduced the heating power consumption of metal oxide (MOX) gas sensors. Specific applications, however, require further reductions far beyond the present state-of-the-art. In this paper, we report on discontinuously operated MOX gas sensors on micromachined heater platforms and show that such sensors allow power consumption levels to be reached w...

    This paper investigates multiarrayed (6 times 6) sensors based on laminated stainless steel membrane on the stainless steel substrate. For the fabrication of those sensors, micromachining techniques are combined with lamination process techniques. For the lamination between diaphragm and substrate, hot pressing technique is used with epoxy resin. The finite-element method is adopted to investigate... View full abstract»

  • Voltage Division Position Sensitive Detectors Based on Photoconductive Materials— Part I: Principle of Operation

    A simple contact structure is proposed for the realization of position sensitive detectors based on a voltage division principle in which the sensors operate in a photoconductive regime. The transfer function of the system is calculated by a detailed analysis of the operative principle of the device. Moreover, the expected performances of the photodetectors are discussed as a function of the main ... View full abstract»

  • Influence of Load Resistance on Time Constants of Laser-Induced Thermoelectric Voltage Signal in La1-xCax MnO 3 and YBa 2Cu3 O 7-y Thin Films

    It is found that in laser-induced thermoelectric voltage (LITV) signal in La1-xCaxMnO3 and YBa2Cu3O7-y.H thin films, both the rise-time and decay time are increasing linearly with the total parallel-connected resistance of the load and the film. To obtain fast laser-induced thermoelectric voltage signal, smaller load should be conne... View full abstract»
