Hydrofoil catamaran sailing at high speed, non-linear movement of the longitudinal movement in its longitudinal movement of the interference of the waves is very intense. In order to improve the performance of airworthiness hydrofoil catamaran, by turning the control flaps provide reduced longitudinal movement of forces and torques required. Established by hydrofoil catamaran vertical linear state-space...
In this paper, we propose a pressure sensor using strain gages bonded on 17-4PH stainless steel (SS) diaphragm based on micro-fused glass frit technology. The strain gages with uniform resistance are obtained by growing an epi-silicon layer on a single crystal silicon wafer using epitaxial deposition technique rather than conventional photolithography and etching techniques. The inorganic micro-fused...
White light emitting diodes (LEDs) with microstructure array on top surface of the phosphor silicone layer are demonstrated to have enhanced the light extraction efficiency (LEE) compared with white LEDs with flat phosphor layer. The effects of microstructure array on the LEE of LEDs are investigated by ray tracing simulations and experiments. Simulation results reveal that spherical cap microstructure...
Thick-film pressure sensors on steel substrate are proven to be robust and low cost, and can be used in many fields such as automotive industries, oil industries and military sectors. In this paper, finite element method (FEM) was used to evaluate residual thermal stresses and the self-heating of the thick film resistors (TFRs) on the offset voltage of the sensor. Results show that the residual stresses...
In this paper, thick film resistors (TFRs) on alumina substrate for strain sensor applications have been developed and evaluated. Thick film technology based ceramic pressure sensors (CPS) are fabricated by screen printing and firing four TFRs on a machined circular diaphragm and then the TFRs are connected in a Wheatstone bridge configuration. Finite element method (FEM) is used to optimize structural...
