    THROUGH-WALL SURVEILLANCE METHODS:

        So-called "millimeter wave" scanning.  This method uses the
        very top end of the microwave radio signal spectrum just
        below infra-red.  To view small objects or people clearly,
        the highest frequency that will penetrate non-conductive or
        poorly- conductive walls is used.  Millimeter wave scanning
        radar can be used in two modes:

        - passive (no signal radiated, uses background
          radiation already in the area to be scanned,
          totally UNdetectable)
        - active (low power millimeter wave "flashlight"
          attached to the scanner just as a conventional
          light mounted on a camcorder), or, the use of
          archaeological ground penetrating radar

    THOUGHT READING:

        Thought reading can be classed as a "through wall
        surveillance" technology.  Thought reading, in the
        unclassified/commercial realm, can be broken down as
        follows:

        - thru-skull microwave reading
        - magnetic skull-proximity reading

    BRAIN ENTRAINMENT:

        The reverse of biofeedback.  Those low frequency electrical
        brain rhythms which are characteristics of various moods
        and states of sleep can not only be read out using
        biofeedback equipment or EEG machines, but using radio,
        sound, contact electrodes, or flashing lights, the moods
        and sleep states can be generated or at least encouraged
        using brain entrainment devices.

        Brain entrainment signals cannot carry voice, which is a
        much higher frequency range.  Brain entrainment can,
        however, be used to "set up" a target to make him/her more
        susceptible to hypnosis.

    These major technology classes can produce some of the observed mind
    control effects, FROM HIDING AND UNDETECTABLY, with the exception of
    remote physical manipulation.
