Anorientation state estimator is proposed for smartweapons applications using feedback fromwide fieldof-view thermal sensors and magnetometers. The state estimation system possesses several key advantages over current designs in that it maintains low cost, lacks moving parts, and is free from reliance on GPS or other state feedback. In order to enhance robustness against disturbances that reduc...

A thermoelectric thin-film device consisting of n-type Bi2Te3 and p-type Sb2Te3 thin-film legs was prepared on a glass substrate by using co-evaporation and annealing process. The Seebeck coefficient and the power factor of the co-evaporated Bi2Te3 film were 130μV/K and 0.7 © 1014W/K2·m, respectively, and became substantially improved to 1160μV/K and 16 © 1014W/K2·m by annealing at 400°C for 20...

COBBER (ClOud OBservER), is a mid-infrared sky monitor featuring a 10μm Perkin-Elmer TPS534 thermopile detector. Radiation is focussed on to the detector through an anti-reflection coated, hemispherical ZnSe lens, providing a 30◦ field of view on the sky. At 10cm in length and 4cm diameter, the tiny cloud monitor was designed for ease of transportation and an extremely low power budget. Run in ...

In this paper, we describe an infrared thermopile sensor comprising of single crystal silicon p+ and n+ elements, with an integrated diode temperature sensor fabricated using a commercial SOI-CMOS process followed by Deep Reactive Ion Etching (DRIE). The chip area is 1.16 mm × 1.06 mm. The integrated diode, being on the same substrate, allows a more localized measurement of the cold junction te...

Concentrating solar applications utilize direct normal irradiance (DNI) radiation, a measurement rarely available. The solar concentrator industry has begun to deploy numerous measurement stations to prospect for suitable system deployment sites. Rotating shadowband radiometers (RSR) using silicon photodiodes as detectors are typically deployed. This paper compares direct beam estimates from RS...
