UC San Diego engineers have developed a wearable patch that could provide personalized cooling and heating at home, work, or on the go. The soft, stretchy patch cools or warms a user’s skin to a comfortable temperature and keeps it there as the ambient temperature changes. It is powered by a flexible, stretchable battery pack and can be embedded in clothing. Researchers say wearing it could help save energy on air conditioning and heating.

The sensor is held in with a black plastic circlip. I'd read somewhere to use a cable tie to pull it out and to avoid losing it in the depths of the engine. In the end mine was quite solid and took quite an attack with a screw driver to get it out and as i'd bought a new one I probably wouldn't have minded if I'd dropped it.
Next I took the electrical connector off which had the usual squeezy bit at the top that clicks over to hold the connector in.
I'm not exactly sure what kind of sensor this is, but it is some kind of microphone or vibration sensor used as feedback to the control board. If the piston starts hitting the ends of it's travel, this sensor picks that up and the power is backed off.

Ha, wow i'm up WAYYYYYY to late at night, misspelled "a while" well there it is. Not important enough to fix. LOL
Had my curtain repaired by Nikon, and they scratched the Sensor! Had it back for 3 months, just wrote it off as welded dust, but got frustrated and looked at it with a loupe and it is a SCRATCH! Having no way of proving this, I am probably going to have to pay Nikon to fix thier mistake.
*Note, I use a rocketblower for most of my dust issues, and Sensor Swabs, with Eclipse for the tough stuff. Spare me messages saying I did this, no one swipes the swab UP on the sensor.*
The green thing is a proximity sensor that you'll see on most any thrill ride and in many other applications. A proximity sensor can detect a metal target in their sensing field (usually an inch away or so) using induction. They help the controller know where trains are located, what position the loading gates are in, if the brakes are open or closed, and other operational aspects of a ride.
I am in the process of building a barometric data logger based on the Arduino coupled with Adafruit's logger shield. I live in between the first two Watchung mountains in north/central NJ, so I thought a drive around town would give me some nice pressure differentials to record.
y-axis is relative changes to the sensor output as they diverge from an initial reading. x-axis is seconds.
this data was collected using an oversampling method to eliminate noise. what happens when you try to get 10-bits of good data but you don't put the MCU to sleep before reading? you get 8-bits of good data (and 2 LSBs of crap). see the previous image in this stream.
there is higher pressure at lower altitudes, so troughs on the plotted data (lower pressure) indicate mountains, while peaks indicate valleys or low areas. kind of backwards but that's the way it is.
no corroboration between sensor outputs and actual pressure values (yet). just diggin' those delta-v's, man.
The MCA Cat III Workboat, owned by Aspect Land & Hydrographic Surveys Ltd, of Ayrshire.
The 'Marine Sensor' is road towable, and with a small forward cabin, can deploy from a slipway or boat hoist / crane and able to operate a wide variety of sensors.
Her hulls and catamaran configuration lend a fast transit speed and give good directional stability resulting in high quality survey data.

The guy at this table seemed annoyed at my being the "4th person" to ask if these were bend sensors. Can you blame me? Anyway, these were very cool. I could press the tip, of either of the left 2 sensors there (which were made of a very thin layer of something I didn't ask about) and watch the red and blue graph lines raise and lower on the monitor to the left of this image. I pressed smoothly and alternately harder and softer with both fingers and made the graphs dance in offset sine waves. It had a very fine resolution (seemingly far greater than 8-bit), no shivering or jumping, and according to Mr. Angsty, were quite durable, having been tested into the millions of presses, with only a very slight decrease in effectiveness, which is easily recalibrated for. They also had a chair loaded up with these things, through which were we treated to a rainbow display of one guy's buttocks pressures, akin to those seen in this buttocks pressures mapping, from the P.E.R.F.E.C.T. workstation. Oddly, the medical field is their biggest market, where they're used, for example, to test for things like blockages in implants.

Halo SMART Sensor detects signs of cigarette smoking or vaping. These could be in areas where CCTV cameras are prohibited and/or not suitable, but where you want them to make sure individuals are protected and illegal or unwanted behavior is recognized. With Halo SMART Sensor, you will have an auxiliary sensor that could help deliver alerts when students are experiencing bullying. Security Systems Texas could also detect when somebody becomes engaged in a fight. The Halo SMART Sensor can also help identify a wide variety of particles in the air so that it can help to prevent the spread of contagious diseases.

The screen shows the light source alignment mode. After the dual light source is attached to the camera, the shutter is opened using the "B" setting and the user verifies visually that the sensors are centered in the film window.
Then the light source is moved until the bar graphs show equal amounts of light. When these levels are satisfactory, tests can be started.
