A bell-shaped vibratory angular velocity gyro (BVG), inspired by the Chinese traditional bell, is a type of axisymmetric shell resonator gyroscope. This paper focuses on development of an error model and compensation of the BVG. A dynamic equation is firstly established, based on a study of the BVG working mechanism. This equation is then used to evaluate the relationship between the angular ra...

Additive manufacturing technologies allow the fabrication of smart objects, which are made up a dielectric part and an embedded sensor able to give real-time feedback final user. This research presents characterization low-cost 3D-printed strain sensor, fabricated using material extrusion (MeX) technology by conductive composed polylactic acid (PLA)-based matrix doped with carbon black nanotube...

It is a challenge to implement loss-of-signal (LOS) circuit with wide threshold voltage range that insensitive temperature. This paper presents new wide-range threshold-programmable LOS detector full temperature compensation for application in 25Gb/s high-speed optical communication receivers. The programmable of the achieved by adjusting peak and gain variable amplifier (VGA). detection accura...

BACKGROUND Robustness to natural temperature fluctuations is critical to proper development in embryos and to cellular functions in adult organisms. However, mechanisms and pathways which govern temperature compensation remain largely unknown beyond circadian rhythms. Pathways which ensure robustness against temperature fluctuations may appear to be nonessential under favorable, uniform environ...
