Speed meter as a quantum nondemolition measuring device for force.
A laser interferometer gravitational wave detector is, in essence, a device for monitoring a classical force (the gravitational wave) that acts on freely moving test masses (the interferometer's suspended mirrors). \Advanced" detectors, expected to operate in the LIGO/VIRGO interferometric network [1] in the middle or later part of the next decade, will be constrained by the standard quantum li...
متن کاملLatency Meter: A device to measure end-to-end latency of VE systems
The effectiveness of virtual environment systems depends critically on the end-to-end delay between the user's motion and the update of the display. When the user moves, the graphics system must update the images on the display to reflect the proper projection of the virtual world on their field of vision. Significant delay in this update is perceived as swimming of the virtual world; objects i...
متن کاملInadequate peak expiratory flow meter characteristics detected by a computerised explosive decompression device.
BACKGROUND Recent evidence suggests that the frequency response requirements for peak expiratory flow (PEF) meters are higher than was first thought and that the American Thoracic Society (ATS) waveforms to test PEF meters may not be adequate for the purpose. METHODS The dynamic response of mini-Wright (MW), Vitalograph (V), TruZone (TZ), MultiSpiro (MS) and pneumotachograph (PT) flow meters ...

متن کاملEnergy Renovation of Buildings Utilizing the U-value Meter, a New Heat Loss Measuring Device
A new device with the ability to measure heat loss from building facades is proposed. Yet to be commercially developed, the U-value Meter can be used as stand-alone apparatus, or in combination with thermographic-equipment. The U-value meter complements thermographs, which only reproduce surface temperature and not the heat loss distribution. There is need for a device that measures the heat lo...
