High-frequency percussive ventilation (HFPV) by the VDR-4(R) has been a successful mode of ventilation in the management of inhalation injuries for nearly 20 years. A limitation of the standard VDR-4 ventilator circuit is that the sliding venturi man

This study evaluated the effectiveness of compliant materials to reduce the level of vibration at the hand from power tools. Material transmissibility was determined so that performance could be compared. Broad-band vibration levels were used as the

The products and technologies employed to produce hardcopy documents, and short-run reproductions of these documents, have changed dramatically in the last two decades. Impact printing devices such as typewriters, daisy wheel printers, and dot matrix

We describe the application of statistical clustering algorithms (approximate fuzzy C-means (AFCM) and ISODATA) and a Bayesian/maximum likelihood (BfML) classifier for data dimension reduction and information extraction with MRI. Analyses were perfor

An efficiency rating system is presented to aid in the selection of hand held air guns, nozzles, and ejectors. This guide is based on noise levels, force or thrust, and air supply pressure. In addition, air consumption, blocked static air pressure, n

When removing waste from paper boxes, pneumatic stripping hammers generate noise from two sources: exhaust air and the internal piston/chisel mechanism. The severity of this noise as a potential operator hazard should be considered in light of the fo

Absorptive treatments for noise control have an important place in an overall engineering control strategy. However, predictions based on the easiest to use method, the Sabine equation, often understate the amount of existing absorption. This is beca

Sixty-five commercial pneumatic mufflers in the size range of 1 /8 to 3/8-inch American Standard Taper Pipe Thread (NPT) were evaluated for noise level as a function of air supply pressure and back pressure. Also, typical directivity pattern and spec
