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.
