Science geek note: the Fresnel lens was invented by a French physicist in the 1800s, and was originally used in lighthouses to concentrate the light beam. Several excellent examples can be seen at historic lighthouses, including several in Oregon.  When seen full size in a lighthouse, they are quite amazing!

Die polizeiliche Beobachtung ist eine Maßnahme der Personenfahndung. Eine Person wird zur polizeilichen Beobachtung ausgeschrieben, indem für sie ein entsprechender Eintrag im Informationssystem INPOL-neu hinterlegt wird. In der Folge werden dann alle Erkenntnisse, die im Rahmen der polizeilichen Arbeit (z.B. bei Verkehrskontrollen) über diese Person gewonnen werden, an die ausschreibende Polizeidienststelle zur Auswertung weitergeleitet. Auf diesem Weg lassen sich Bewegungsprofile erstellen oder Zusammenhänge zwischen der beobachteten und dritten Personen herstellen.

These little puppies are simply thin, flexible, plastic magnifying glasses. About the size of a credit card, they are dirt cheap, magnify to about 3x power, and really help to read that 8 point font. (The image clarity is not as good as what you’d get with a lens actually made of glass, but it’s probably  good enough to read your map and make the correct trail choice.)

So, the way I heard the story . . . Several older and experienced hikers were hiking in the Columbia River Gorge. As light was fading, they needed to make a route choice at a trail junction. They pulled out their map . . . and couldn’t read it because no one had reading glasses! They didn’t know where to go, and decided to stay put for the night.
