  • Frequency Response of Double-Ended Socket and Probe Configuration (.pdf)
    path. QA's wireless X Probes and Double-Ended Sockets address the limitations of fixture wiring by eliminating the wire.
  • Quality Control of Sound on Film
    In performing quality control of the sound quality on film, the customer requires a fairly slow sampling and very high vertical resolution. Because the customer does not produce the actual film, there is a need to double-check the sound quality before it hits the theatres. Being sound, the highest
  • Transformerless UPS Systems (.pdf)
    with a transformer, or multiple smaller UPS power modules paralleled together to achieve the required capacity. Most UPS manufacturers are finding it difficult to create a true on-line double conversion transformerless UPS system larger than 200 kW due to factors such as ground faults, high frequency noise
  • Generating Grayscales on ICEBrite VGA Displays - AN119
    , such as SMOS and Cirrus Logic, also provide methods to generate grayscales. Planar's ICEBrite displays use a similar video interface to those used by many VGA-sized (640x480 addressability) monochrome LCDs. Planar's ICEBrite displays have a maximum frame rate frequency of 120 Hz, about double the maximum frame
  • Smaller really is better
    for testing and certifying Navy antenna systems. The conclusion: smaller is better. Vincent's Plano Spiral Top Hat 7-MHz antenna, for example, is half the size of a normal quarter-wave antenna operating at that frequency. The URI antenna gain matched that of the ideal quarter-wave antenna, and its bandwidth
  • Dynamic Testing Uncovers Rheology of Rubber
    ). Temperature was controlled to 125°C. The test specimen is a double lap shear sample with thickness of 4 mm and 800 mm2 area (20 mm by 20 mm). The transmitted force is measured using a strain gaged load cell. Timed data is analyzed using an FFT to determine the amplitude and phase relation
  • Solid structures for machining centers
    for accuracy and productivity. Most machines on the market tend to have similar portal designs with stationary, rigid double columns for stability. Where they differ is in the mounting positions for the Y-axis slide. The slide may be vertical, at 45 or 60 angles, or horizontal, and this can impact
