Noise levels produced by high-frequency oscillation
for patients with severe respiratory failure. Although the technology has advanced in recent times, the noise levels produced by such devices remain high. Exposure to excessive noise in intensive care may cause hearing problems for both staff and patients following long-term exposure. We investigated the noise level in decibels produced by a SensorMedics 3100B ventilator (SensorMedics, Bilthove...
متن کاملBreakdown characteristics of high pressure xenon lamps
An investigation of the breakdown of high intensity discharge (HID) lamps filled with xenon at pressures from 0.1 to 5 bar is presented. Three power supplies were used in order to provide voltage rates of increase covering about four orders of magnitude from 5 mV ns−1 to 100 V ns−1, the latter being typical for electronic ballasts driving commercial HID lamps. Customized lamps ensure a volume b...
متن کاملPreventing mercury vapor release from broken fluorescent lamps during shipping.
Fluorescent lamps are estimated to annually release 1 t of mercury into the air in the United States; transport of used lamps may play an important role in these emissions. In 1999, the U.S. Environmental Protection Agency added lamps to the universal waste rule to encourage recycling by allowing shipment to recycling facilities by common carrier. The rules required that lamp packaging must be ...
متن کاملHigh-Frequency Dimmable Electronic Ballast for Automotive HID Lamps
This paper presents a high-frequency electronic ballast for HID lamps. A new fixed frequency dimming method with low EMI features is developed in this research. The proposed electronic ballast has the advantages of high power density, simple circuit and low EMI features. The circuit operating principle and design procedures are described in detail. A laboratory prototype was built and tested. T...
متن کاملZinc and sodium high pressure lamps for curing composite resins.
Polymerisation characteristics of conventional units for curing composite resins are insufficient considering handling feasibilities particularly in the premolar and molar region. There is also hazardous ocular effect of near ultra-violet part of visible spectra. Sodium high pressure lamp technology has been applied to develop a new high pressure zinc lamp, which is for the first time used for ...
