To understand the behavior and fate of juvenile salmon (and funded by the U.S. Army Corps of Engineers), researchers from Pacific Northwest National Laboratory and the National Marine Fisheries Service developed a sophisticated yet simple underwater acoustic fish tracking system. The system consists of autonomous receivers, anchored to the bottom of the river, and microtransmitters on the fish. Flat round anchors are attached to the long yellow receivers or nodes to keep them in place on the turbulent river bottom.

IR sensor voor Fischertechnik kogelbaan. Ook een nieuwe extra curve 180° is bijgevoegd. De IR sensor kan werken op 5V en op 9V. Hij is niet gevoeilig voor omgevings licht. Zelfs getest in volle zon blijft hij correct werken. Het stroomverbruik dooe de IR diode is ongeveer 9mA en de load voor de Phototransistor is 5 mA. Burst van kogels worden mooi verwerkt.

Research at Baskett Wildlife Research and Education Center is looking at the effect of climate change on Missouri forests. Sensors scattered throughout the forest monitor carbon sequestriation and moisture moving through the soils and roots. Each half hour the sensor uses lasers to analyze what is going on below the surface.

Yay!! My sensor was getting so dusty...it was driving me nuts!
When cleaning your sensor, do NOT used forced air! You will only be pushing dust particles deeper into your camera and making more of a problem for yourself.
I highly recommend Nicholas of Copper Hill Images well documented method. Take your time and take care and you will be able to do it yourself.

A sensor designed to detect a change in gait. Intended to help prevent the kind of falls that disable seniors and vastly increase healthcare costs.
Three rate gyros, a 3-axis accelerometer and a 3-axis magnetometer (compass). The ultimate goal for my new KAP rig is to have a stabilized camera platform referenced to the local geo-spatial coordinate system.
Look out, I've got digital sensors and I'm not afraid to use them.
The gauges are large, classic and easy to read (go figure) but the wheel is large and skinny. But isn't that part of the charm?
(Also try it on black.)
I recently had my sensor cleaned at Pro Photo Connection in Irvine

and wanted to checkity check the results, no spots here...
Nice work Gunther!

My camera sensor evidently looks like the inside of a vacuum cleaner bag - full of dust. Alas... I will have to do something about it. I know... the alignment is bad, but no time. Wanted to at least take a picture for the week.
Before and after pics from cleaning my D600 sensor for the first time.
I used Sensor Swab Type 3 and the Eclipse Optic Cleaning Fluid, both bought from Amazon.com

It took 4 swabs to get it 99% clean (3 would have been fine, but I was being OCD about 1 tiny spec). Here is the before and after in full resolution!
Shot with the Tokina 17-35, F14, ISO 800, 1/4s for all shots, around 17-19mm. AWB made the last photo a bit different colored, but you get the point :)
Total end cost to me was about $47, which is less than a typical shop sensor cleaning, and I still have 8 swabs left -- good for another 2 or 3 cleans hopefully!
This was created for Flaghead Photographic at a recent Triggersmart seminar. The PIR sensor picks up on moving heat signatures so we dropped warmed up vegetables into a nice Thai bowl to demonstrate this function as we couldn't get a wild animal into the studio!
There's a blog about the seminar here - www.dephotographic.com/blog/triggersmart-workshop-decembe...
