The Solenoidal Tracker at RHIC (STAR) is a detector which specializes in tracking the thousands of particles produced by each ion collision at RHIC. Weighing 1,200 tons and as large as a house, STAR is a massive detector. It is used to search for signatures of the form of matter that RHIC was designed to create: the quark-gluon plasma. It is also used to investigate the behavior of matter at high energy densities by making measurements over a large area.

This is an Arduino-based Motion Detector I created. Upon pressing the button, it will arm 10 seconds later. Then beep and blink the LEDs when motion is detected. It can be disarmed by pressing the same button. The code is as follows:

I know everyone has done this before. RFID and arduino that is. But looking at the example code it looks like the antenna is always in receive mode. I am not sure how this affects the life of the chip / reader but I thought of adding a way to detect human presence before activating the receiver.
I found some little IR heat detector (here: www.allelectronics.com/make-a-store/item/IRD-10/INFRARED-... and tossed together some analog read code and viola. Now when the IR detector detects over a certain variable heat temp it activates the RFID reader.
I will post the code and write up on my blog.

The three were recognized by the Federal Laboratory Consortium for work in commercializing the technology, which needs no battery or electric power or special laboratory equipment, is hardy against wide temperature variation and can detect very small numbers of B. anthracis spores. The detector was licensed by a New Mexico company.

Two antineutrino detectors in Daya Bay Hall #1, shown prior to the pool being filled with ultrapure water.
Brookhaven National Laboratory plays multiple roles in the Daya Bay Reactor Neutrino Experiment Collaboration, ranging from management to data analysis. In addition to coordinating detector engineering efforts and developing software and analysis techniques, Brookhaven scientists perfected the “recipe” for a special, very chemically stable liquid that fills part of Daya Bay’s detectors. When antineutrinos react within the detectors, this liquid emits very faint flashes of light that can be detected.

The last caveman has been found in a nano-cave.
During the study of cross-sections prepared by FIB on InN-AlN core-shell nanowires, a region containing five nanowires was being analysed by HAADF-STEM. However, our scientific intuition told us something else was waiting to be discovered, hiding behind Z-contrast…
With a single click, we switched to the ADF detector. All strain effects coming from the core-shell structure arose and revealed what was hiding behind: the last caveman. Or how we call him: THE NANO-CAVEMAN.
Is (S)TEM the new revolution in paleoanthropology? Only time will tell…

PHENIX is one of the four large detectors that helps physicists analyze the particle collisions at Brookhaven's Relativistic Heavy Ion Collider (RHIC). PHENIX weighs 4,000 tons and has a dozen detector subsystems. Three large steel magnets produce high magnetic fields to bend charged particles along curved paths.
Wearing a mock suicide vest, Albuquerque businessman Robby Roberson stands in front of his company’s CBD-1000 bomb detector, being adjusted by Sandia National Laboratories scientist JR Russell. Russell worked with R3 Technologies to iron out technical issues and bring the suicide bomb detector close to commercialization.

There are nearly 5,000 different kinds of ladybugs worldwide and 400 which live in North America.
A female ladybug will lay more than 1000 eggs in her lifetime.
A ladybug beats its wings 85 times a second when it flies.
Aphids are a ladybug's favorite food.
Ladybugs chew from side to side and not up and down like people do.
A gallon jar will hold from 72,000 to 80,000 ladybugs.
Ladybugs make a chemical that smells and tastes terrible so that birds and other predators won't eat them.
If you squeeze a ladybug it will bite you, but the bite won't hurt.
The spots on a ladybug fade as the ladybug gets older.
During hibernation, ladybugs feed on their stored fat.
Ladybugs won't fly if the temperature is below 55 degrees Fahrenheit.
The ladybug is the official state insect of Delaware, Massachusetts, New Hampshire, Ohio, and Tennessee.
The male ladybug is usually smaller than the female.
The Asian Lady Beetle can live up to 2-3 years if the conditions are right.
Overview of the timings from the detector. To simulate the ambient light one IR laser is set in continue mode. The signal level on the detector for this simulated light was about 65 ( right side diagram) the ADC has a range of 2.56V, so 65 means .65V or 650 mV. The left side of the diagram show where the second but now pulsed IR laser come in action. This pulsed light goes now to level 105 or 400 mV above the simulated ambient.
On the diagram you see also how long its take to transfert a data string via the SPI bus. This time is 1.83 usec to transfert one 8 bit ADC value. The total cycle time for 2 measurements is 65.35 usec. On the diagram you see also where the laser drive is on and off. The AVR controller runs on the internal clock of 8 MHz.
