Simple Interferometric Manometer

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...

Integrated Digital Manometer for Lumbar Puncture

A simple manometer for the continuous measurement of intra-ocular pressure.

THE adequate measurement of the intra-ocular pressure, both clinically and experimentally, has remained a baffling problem. The tonometer has obvious disadvantages whiclh have been summarized by Duke-Elder (1932). Chief amongst these, in the opinion of the present authors, is the possibility of self-deception, since the variations in the results of repeated determinations are often quite large ...

U-Tube Manometer Calibration using ANFIS

This paper deals with the implementation of the Adaptive neuro fuzzy inference system (ANFIS) on a Xilinx based Field Programmable Gate Array Spartan-3E. The implemented hardware is then used to efficiently calibrate the U-Tube manometer, in which the relation between the level of mercury and the Capacitance developed across the Copper Plates of the manometer is highly non-linear. This system s...

An intracardiac manometer: its evaluation and application.

The miniature intracardiac manometer supplied a method for recording artefact-free pressure tracings from the heart and great vessels of man and the intact animal. This instrument has been applied to the procedure of cardiac catheterization. It has also been used to demonstrate that if motion artefacts can be minimized, the central pulse can be recorded with reasonable accuracy by means of mano...
