A miniature Wright peak-flow meter.
A new miniature Wright peak-flow meter has been designed and produced. The meter is tubular with a spring-loaded piston and a longitudinal slot through which air escapes. Its dynamic characteristics have been carefully designed to make it respond only to peak flow and not to rate of rise. Performance tests on early instruments showed fairly close correlation with the Wright peak-flow meter but ...
متن کاملComparison of the new miniature Wright peak flow meter with the standard Wright peak flow meter.
Preproduction and current models of the miniature Wright peak flow meter have been compared with the standard Wright peak flow meter on normal and abnormal subjects. Early problems in production appear to have been overcome, and the current model agrees to within 3% with the standard peak flow meter, which is as close as the agreement between two standard instruments. The new mini-meter may be ...
متن کاملHow to cheat with the miniature wright peak flow meter.
In February, 1982, Chest published an article concerning a new and innovative unit at Bethesda Medical Center in St. Paul, Minnesota. This unit is an Inpatient Service kr patients with chronic respiratory problems who cannot be maintained in a home setting. We have found, however, that with rehabilitation, education and appropriate support services, many of our patients could be discharged. Med...
متن کاملInkjet 3D Printed Miniature Water Turbine Energy Harvester-Flow Meter for Distributed Measurement Systems
An energy harvester fabricated by inkjet 3D printing based on miniature water flow turbine with mechanical and electrical components necessary for electrical energy generation is shown. Turbine (outside diameter 25.4 mm (1”) and 14 mm length) is able to generate electric power of 4 mW for 14 L/min of water flow and it gives 0.7 V for optimal load resistance (RL = 55 Ω). The harvester itself may...
متن کاملAsa Options
Adaptive Simulated Annealing (ASA) is a C-language code that finds the best global fit of a nonlinear cost-function over a D-dimensional space. ASA has over 100 OPTIONS to provide robust tuning over many classes of nonlinear stochastic systems. These many OPTIONS help ensure that ASA can be used robustly across many classes of systems. Ke ywords: simulated annealing, nonlinear systems Most rece...
