A general note of interest and a warning. One of my clients just
contacted me to say that the "fairly inexpensive and portable"
motion detector (they have yet to tell me what make and model) that
they just purchased to protect a particular display that attracts
unwanted hands is set off by cell phones.  I suggested that this was
a great opportunity to ban cell phones from the public galleries,
but that seemed to fall on deaf ears (sorry). Currently they are
looking at more expensive versions that are shielded from the impact
of cell phone frequencies.
