  • Method and apparatus for identification of biological material
    Patent number: 8723106
    Abstract: Biological material is detected in a sample using a MALDI-MS technique (Matrix Assisted Laser Desorption and Ionization-Mass Spectroscopy). A liquid comprising the sample and a MALDI matrix material is prepared and used to form a continuous stream of the liquid. The stream is separated into successive parts to form drops, which are launched into flight, or the stream is launched into flight and then separated into drops. Drop forming techniques may be used that are known from ink jet printers. Material from the drops is ionized while in flight. Mass spectra from the ionized material of respective drops are measured. Preferably, before the drops are formed the liquid is diluted to a level where the majority of drops at most one micro-organism is present per drop.

  • Aircraft ground run-up enclosure
    Patent number: 7600605
    Abstract: A ground run up enclosure (10) which comprises an air inlet structure (12), a test chamber (14), an acoustic enclosure (16) and a main enclosure door (118). The air inlet structure (12) is adapted to receive ambient air and redirect it into the test chamber (14). The test chamber (14) is designed to receive a portion of an aircraft (20) therein. The acoustic enclosure (16) receives the airflow from the test chamber (14). The airflow continues through the acoustic enclosure (14) until it contacts a front surface of the main enclosure door (118) and is redirected upward and out of the enclosure.
