| 21. | James Zimmerman had just developed an extremely sensitive detector called the SQUID ( " Superconducting Quantum Interference Device " ).
|
| 22. | They used some more particles and they used a more sensitive detector, so they could see a very small signal.
|
| 23. | The VK-9 digital organ, for example, offers a proximity-sensitive detector that triggers the Leslie speaker, a ring modulator, or other effects.
|
| 24. | This allows the lysin to be a quick and sensitive detector for anthrax spores that might be used in an attack.
|
| 25. | And even with very high magnification and an extremely sensitive detector, PICA detects fewer than 1 percent of all emitted photons.
|
| 26. | One powerful technique involves moving the signal of interest to a higher frequency and using a phase-sensitive detector to measure it.
|
| 27. | To obtain clearer results, in 1969 Cohen built an elaborate shielded room at MIT, but still needed a more sensitive detector.
|
| 28. | Extremely sensitive detectors must be used in SAFARI to gain maximum benefit from the low infrared emissions of SPICA s cooled mirror.
|
| 29. | The International Olympic Committee claims its super sensitive detector can sense the use of illicit drugs as far back as eight weeks.
|
| 30. | The search for WIMPs involves attempts at direct detection by highly sensitive detectors, as well as attempts at production by particle accelerators.
