PNNL’s improved Sensor Fish is a small tubular device filled with sensors that analyze the physical stresses fish experience as they pass through dams and other hydropower structures. The device’s latest version costs about 80 percent less and can be used in more hydro structures than its predecessor, according to a paper published in the journal Review of Scientific Instruments.

Here is an older picture, as I am without my 5d at the moment.
Working on the Heidelberg exposed Set, revealed how desperate my MkII was in need of some serious sensor cleaning (Thx Russ). After weeping over messed up shots, I brought the cam in and will be able to pick it up on Tuesday.
It feels weird not having my Cam, like something is missing.

"these two modes of invisibility - that which is hidden behind the things that we see, and that which is hidden inside the things we see - lend a pervasive sense of enigma, and unknowableness, to the everyday world of our direct experience. a sense that we are in continual, felt relationship with the unseen. it is a sensation that readily dissipates, however, when we abstractly ponder this earthly world as though we were not entirely a part of it, considering nature with the cool detachment of an engineer gazing at his blueprints on the wall, or that of a spectator watching a satellite image of the earth projected on the flat screen of her computer. however, as soon as we return to the immediacy of the present moment, and hence to our ongoing, animal experience in the midst of this sensorial world, then the flatness dissolves, and the enigmatic depth of the world becomes apparent."

This photo is taken with a 32 year old lens (!). The Nikon 135mm f/2.8 from 1980. It's the predecessor to the modern portrait lens, 135mm f/2.0 DC.
This lens produces very unique and lovely looking images at 2.8, though it is mildly soft at this aperture. It goes all the way to f/32. Something I've never seen in such an old lens. Those others I've got has maximum of f/22 and f/16. Has not had the chance yet to shoot at max aperture.

Agfa Silette LK Sensor, introduced 1970, perhaps one of the last Silettes and an early Agfa with the red shutter release button. The body is based on the Agfa Optima 200 from 1968.
It is a low-budget camera, the lens barrel and the housing are made of plastic, though the top and the bottom look like metal. This camera hasn't a rewind crank, the rewinding is done by the advance lever, when the button "R" is tripped before, so the inner mechanism is complex.
The lens is a Color-Agnar 2.8/45 mm with three elements, the shutter is a Parator with 1/30 to 1/300 s and B. The Selenium exposure meter is coupled and the match needle is displayed in the viewfinder and on top, the ASA range is from 25 to 400 ASA. All settings has to be done manually, like on all Silettes, I think. The LK has a thread for a cable release on the backside and a hot shoe. There is no self-timer, no focussing aid and the frame counter has to be reset manually.
(If you want to remove the top plate: there is a third screw hidden in the hot shoe. The cover in the hot shoe has the most diabolic clip mechanism I've ever experienced.)

Camera is currently being fixed at Nikon's, I hope this will be its last trip.
Medtronic Continuous Glucose Monitoring
Update: I am now, as of October 2017, using the Guardian Sensors with the 760G insulin pump. Same look different tech. Not a fan, as of December, as the sensors are supposed to last 7 days. Mine quit on day 6.
Principal investigator Jacques Loui, left, and a firmware developer are part of a team redesigning high-performance radar as a flexible, multipurpose sensor.
Researchers are working to replace legacy analog radars commonly used by the military with a new, digital, software-defined system called Multi-Mission Radio Frequency Architecture. The overhauled design promises U.S. warfighters unprecedented flexibility and performance during intelligence, surveillance and reconnaissance operations, even against sophisticated adversaries.

At Pacific Northwest National Laboratory, researchers are conducting cutting edge work to build highly efficient, noninvasive sensors based on carbon nanotube technologies. For example, researchers are building a sensor based on enzymes that self-assemble layer by layer onto tiny hallow carbon tubes. When the sensor encounters organophosphates, the active agent in certain insecticides and chemical warfare agents, the enzymes slow down. The reduced activity is transmitted as an electrochemical signal through the carbon nanotubes to the attached electrode. The resulting measurements can show the concentration of organophosphates in a person's saliva, a city's water supply, or other contaminated waters.

Modeling the new black & gold & "Gold 45 Revolver" Gold'N'Virtue swimsuits with the main equation to Moving Dimensions Theory on the swimsuits: dx4/dt=ic. Yes I have a Ph.D. in physics! :) You can read more about my research and Hero's Odyssey Physics here:
herosodysseyphysics.wordpress.com/ MDT PROOF#2: Einstein (1912 Man. on Rel.) and Minkowski wrote x4=ict. Ergo dx4/dt=ic--the foundational equation of all time and motion which is on all the shirts and swimsuits. Every photon that hits my Nikon D800e's sensor does it by surfing the fourth expanding dimension, which is moving at c relative to the three spatial dimensions, or dx4/dt=ic!
This actually isn't from a Gibson GL1RA 045N-08A. This flame sensor is similar and seems to work fine, but it's shorter than the OEM part.

Cheyenne linemen install sensors on a lattice steel structure on the Ault-to-Hayden 345-kilovolt line. The sensor will measure conductor or static temperature, current, movement along every axis and the speed of the motion. Using this data, maintenance crews and engineers are investigating if spacer dampers on this line need to be replaced and if a different configuration may better prevent the conductors from hitting each other.

I was trying to clean my sensors on a Nikon D600 and D7000. The Bblow bulb i used had a plastic tip that shot out of the end and i was worried i may have cracked the mirror!
A version of Sandia National Laboratories’ advanced sensor, called Icarus, is displayed separate from its ultra-high-speed, burst-mode camera. An Albuquerque-based startup plans to make the highly sought tech available to new markets.

"All Optimas have:
a HUGE brightline viewfinder that makes them useful to people with glasses;
one single thumb lever that winds or rewinds the film, depending on the polarity set by a push button;
a foolproof quick-loading system;
the big Sensor shutter release with a clear pressure point;
automatic exposure;
an f/2.8 lens (fast and practical);
a plastic slab that (briefly) protects the exposed film from fogging when you accidentally open the back;
a plastic-coated, all-metal body.
The Optimas are very transparently designed cameras (albeit very German in appearance and strangely reminiscent of the Plaubel Makina 6×7), and very compact too. They have an outer shell of plastic-coated metal and mostly metal internals, which makes them very durable. There are a lot of plastic parts, some of which are fairly vital like cogs and such, but I think that here plastics are not so much synonymous with cheapness and shoddiness, but with optimized mechanical characteristics and manufacturability."
A simple heartbeat sensor for arduino. Communicates each beat to the computer via serial over USB. A little script in Processing sends OSC messages to SuperCollider which makes a sound. Processing also displays a graph of beats per minute readings from the Arduino.
This version sends serial messages over the USB connection, a later version sends OSC messages over ethernet (even cooler!) (http://www.flickr.com/photos/chuck_notorious/4041494889/).
Next step: use the Arduino Ethernet shield to send OSC messages directly.
Next Next Step: Use this as part of a cool multimedia performance!

Sandia National Laboratories researcher Ronen Polsky holds a prototype of a microneedle fluidic chip device able to selectively detect and painlessly measure electrolytes in the interstitial fluids that bathe skin cells. It features nine sampling needles, each only 800 millionths of a meter (microns) in height, and beneath them, a fluidic channel that can draw interstitial fluid over nine gold disk electrodes. Each disk can be tailored to detect a different analyte. The visible rectangular gold pads are electrical contacts.
