Wide Dynamic-range Low-power current-mode Optical Sensor Readout

Optical sensor has been widely used in daily life. One of the important applications of optical sensors is the ambient light sensor installed in portable devices. The screen brightness of portable devices like smartphones is designed to be automatically adjusted based on the ambient environment. The ambient light detection is realized using...

Design of an MR-safe haptic wrist manipulator for movement disorder diagnostics

Tremor, characterized by involuntary and rhythmical movements, is the most common movement disorder. Tremors can have peripheral and central oscillatory components which properly assessed and separated may improve diagnostics. An MR-safe haptic wrist manipulator enables simultaneous measurement of proprioceptive reflexes (peripheral components)...

Optimization of Pd Surface Plasmon Resonance sensors for hydrogen detection

A design to optimize a fiber optic Surface Plasmon Resonance (SPR) sensor using Palladium as a sensitive layer for hydrogen detection is presented. In this approach, the sensitive layer is deposited on the core of a multimode fiber, after removing the optical cladding. The light is injected in the fiber with a given wavelength and all fiber...

Automatic sensor management: Challenges and solutions

Due to technical advances and the changing political environment sensor management has become increasingly knowledge intensive. Aboard navy ships however, we see a decrease of available knowledge, both quantitative and qualitative. This growing discrepancy drives the need for automation of sensor management. Since the goal of sensor deployment...
