The Chicxulub impact (in the northern Yucatan Penninsula, Mexico) marks the Cretaceous-Paleogene (K-Pg) boundary and is implicated in one of the five major extinctions. Researchers have examined ejecta from the Chicxulub impact, and most recently a d

A wireless HART adapter is a self-powered device that harvests power from the 4 ‥ 20mA current loop. It wirelessly transmits the digital information present on the loop. Such adapters can be retrofitted to in-place current loops if the voltage loss

An intrinsically safe and self-supplied wireless adapter has been developed for HART devices. The adapter works with a supply voltage down to 1.4V and a supply current as low as 3mA. To achieve this, analogue and digital low power design approaches,

Thermal mass flowmeters are based on the measurement of the heat transfer from the sensor into the moving fluid, which is given by King's law. A coating of the sensor element changes the heat transfer from the sensor to the fluid and leads to an erro
