High Frequency Inductance Manometer for Gaseous Reaction Studies

A Combination Simple Manometer and Constant Volume Differential Manometer for Studies in Metabolism

The purpose of this article is to describe a manometer which we have developed during the past year for studies in metabolism and which appears to include a number of features of wide-spread use and interest. It is a combination manometer, offering in a single apparatus the possibilities of either direct or differential manometric measurements. For direct measurements it is the equivalent of tw...

High-speed microfluidic differential manometer for cellular-scale hydrodynamics.

We propose a broadly applicable high-speed microfluidic approach for measuring dynamical pressure-drop variations along a micrometer-sized channel and illustrate the potential of the technique by presenting measurements of the additional pressure drop produced at the scale of individual flowing cells. The influence of drug-modified mechanical properties of the cell membrane is shown. Finally, s...

High Resolution Switching Mode Inductance-to-Frequency Converter with Temperature Compensationti

This article proposes a novel method for the temperature-compensated inductance-to-frequency converter with a single quartz crystal oscillating in the switching oscillating circuit to achieve better temperature stability of the converter. The novelty of this method lies in the switching-mode converter, the use of additionally connected impedances in parallel to the shunt capacitances of the qua...
