The PEPE instrument reported that the comet's fields were offset from the nucleus.

Once at a target, DS1 senses the particle environment with the PEPE ( Plasma Experiment for Planetary Exploration ) instrument.

Burroughs was able to use the basic design for only one commercial system, the Parallel Element Processing Ensemble, or PEPE.

PEPE was designed to allow high-accuracy tracking of 288 incoming ICBM warheads, each one assigned to a modified PE.

Burroughs built only one PEPE system, although a follow-on design was built by Bell Labs.

“ They may produce global epidemics and impair the health of future generations .” He then stated that, in recognition of these dangers, the United States had decided to destroy its entire stockpile of biological agents and confine its future biological research program to defensive measures, such as vaccines and field detectors.

2D / 3D reconstruction: Early PET scanners had only a single ring of detectors, hence the acquisition of data and subsequent reconstruction was restricted to a single transverse plane.

All of the solar neutrino detectors prior to SNO had been sensitive primarily or exclusively to electron neutrinos and yielded little to no information on muon neutrinos and tau neutrinos.

Success, however, had to wait until after World War II, during which the attempt to improve silicon and germanium crystals for use as radar detectors led to improvements both in fabrication and in the theoretical understanding of the quantum mechanical states of carriers in semiconductors and after which the scientists who had been diverted to radar development returned to solid state device development.

Setups where the contacts were close enough were invariably as fragile as the original cat's whisker detectors had been, and would work briefly, if at all.

The Michelson or Fourier transform spectrograph was popular for infra-red applications at a time when infra-red astronomy only had single pixel detectors.

This machine had 30 photomultiplier tubes as detectors and completed a scan in only 9 translate / rotate cycles, much faster than the EMI-scanner.

In fact, readings from instruments at the plant and off-site detectors had detected radiation releases, albeit at levels that were unlikely to threaten public health as long as they were temporary, and providing that containment of the then highly contaminated reactor was maintained.

Scientists had long known of this fact by the time detectors were developed that could selectively detect desirable metals, while ignoring undesirable ones.

Many detectors in the 1970s had a switch which enabled the user to switch between the discriminate mode and the non-discriminate mode.

Having worked previously on aspects of radio and radar, his attention had become focused on solid state physics, because of the importance of semiconductors in the development of electronics and infra-red detectors.

The crew complained of headaches before realizing the carbon dioxide detectors had failed to alert them to change the air purifiers.

Prior to the introduction of the Audion, radio receivers had used a variety of detectors including coherers, barretters, and crystal detectors.

Early infra-red detectors had poor sensitivity, so could only track the hot exhaust pipes of an aircraft.

The pilots did not consult the vibration detectors because these instruments, on previous planes they had flown, were notoriously unreliable.

Extractor fans to clear the then activated, and firefighters with breathing apparatus and gas detectors checked through the dam to ensure it had cleared.

However, he had to cover the cost of U. S. Marshals and metal detectors for the wedding and would have 6 hours maximum.

The building had no automatic fire alarm, no rate-of-rise heat detectors, no direct alarm connection to the fire department, no fire-resistant stairwells, and no heavy-duty fire doors from the stairwells to the second floor corridor.

The Large Electron – Positron Collider had four detectors, built around the four collision points within underground halls.

If we had other sense organs altogether, like infra-red detectors or echo-location devices, we can barely imagine how things would appear to us.

Compared to underground detectors like Super-Kamiokande in Japan, AMANDA was capable of looking at higher energy neutrinos because it is not limited in volume to a manmade tank ; however, it had much less accuracy because of the less controlled conditions and wider spacing of photomultipliers.

The instrument used two digicon detectors, ' blue ' and ' red ', and had a spectral resolution of about 1300 over the 115nm to 850nm range.

The energy exchange between the electron beam and the sample results in the reflection of high-energy electrons by elastic scattering, emission of secondary electrons by inelastic scattering and the emission of electromagnetic radiation, each of which can be detected by specialized detectors.

At the end of the beamline is the experimental end station, where samples are placed in the line of the radiation, and detectors are positioned to measure the resulting diffraction, scattering or secondary radiation.

Also, the secondary mirror is undersized to avoid edge detectors viewing warm structure outside the edge of the primary ; this means the aperture seen by any point in the image plane is 3. 7 m. This design requires the camera's vacuum cryostat – which cools the detectors as well as the baffles – to be more than 2 m long, with a front window of 95 cm diameter.

The image plane of the camera also has wave front detectors used to control the shape of the primary mirror and the position and tip / tilt of the secondary mirror ( active optics ).

Surface detectors typically use Cherenkov detectors or Scintillation counters to detect the charged secondary particles at ground level.

An array allows for detection of secondary particles caused by a single cosmic ray at several detectors.

The EPD used silicon solid state detectors and a time-of-flight detector system to measure changes in the energetic particle population at Jupiter as a function of position and time.

All semiconductor detectors function rather inefficiently in crystal receivers, because the low voltage signal level is too low to result in much difference between forward better conduction and reverse weaker conduction.

The first example of an electrical resonance curve was published in 1887 by German physicist Heinrich Hertz in his pioneering paper on the discovery of radio waves, showing the length of spark obtainable from his spark-gap LC resonator detectors as a function of frequency.

With dual output FD detectors, headphones can be used to monitor both outputs simultaneously, or the loudspeaker used with the heterodyne function and the FD output recorded and analysed later.

Dual FD / heterodyne detectors are useful for cross country transects especially when there is a function provided for recording voice notes such as times, locations and recognised bat calls.

Using barrels and tanks of carbon tetrachloride as detectors, Davis characterized the rate of the production of < sup > 37 </ sup > Argon as a function of altitude and as a function of depth underground.

In many detectors this can also be a function of time, for example in astronomical telescopes it is common to take a dark-frame of the same time as the planned light exposure.

The conundrum of this thought experiment lies in the idea that the wave function interacted with the inner shell, causing a partial collapse of the wave function, without actually triggering any of the detectors on the inner shell.
