Paddle wheel sensors are not known for their accuracy. They also tend to be nonlinear, showing higher turns per liter at higher velocities than at lower...
Often, catheters have heating parts and they need irrigation – a constant stream of saline to prevent the surrounding tissue from drying out. The rate is...
my 2 semester project i started this semester is an RC blimp that we are going to make autonomous. part of the project involves recognizing that it is above a...
You could put an IR LED on the target pointing upwards and a phototransistor on the blimp. When the blimp sees the cone of light from the target, it descends....
If you could put a camera on the blimp you could optically center the target LED. You could also use acoustics. Because of weight I would put a pinger on the...
some of you are thinking the same as us. we are going to be flying it indoors, because its going to be a small blimp(6 to 8 feet), so GPS is out. we are...
... To determine where the blimp is in the indoor environment would be a tough part. If you figure out how to do it well, you could extend your solution to...
CFP - 5th International Colloquium on Signal Processing & Its Applications 2009 Dear Sir/Madam, The Advanced Signal Processing (ASP) Research Group, Faculty of...
I have a lab project and we're measuring the deflection of a 12"x12" steel plate (1/8" thick) due to an explosion. Optical instruments and those requiring long...
@&^#& - I just typed a very long reply and got an abnormal response after posting - so I don't know what happened to my response. I think that any deflection...
Hello All, I'm new to this forum and I am seeking some information on a certain ultrasonic transducer element, PE-50. It's a 1" diameter ceramic piezoelectric...
Hi All, I am working on the Design of a Magnetic Sensor, this sensor is a part of security system. This sensor should be able to detect human intrusion, can...
You could have a coil generating a high frequency field, and then use a sensing pick-up coil to measure variations in this field. However, this forms pretty...
The human body has a miniscule magnetic signature. Why do you want to use a magnetic sensor? You will probably pick up watches, belt buckles, rings on...
A plate would work but an outer ring around the room at various field projection points that bounce back to the plate will indicate where the intruder is...
... Shafali, Start with the name -- I think you mean dissertation, not Dessertation. See: http://en.wikipedia.org/wiki/Dissertation. Profs can get really...
Along the past few years, Ain Shams University Students’ Scientific Society has annually organized one of the world’s most well renowned and prestigious...
hi i have used this sensors about one year but i always have used +5 dc volts as the power but i now want to supply heater with pulses but i dont know with...
Disclaimer: I've never used the MQ series sensor. I've just read the datasheet. Why do you want to drive the heater with pulses? Do you want to turn the...
If any of you are familiar with the Nintendo Wii remote, it uses a Pixart Multi Object Tracking Sensor to track up to 4 IR sources. I am looking for an IR...
Im looking for an optical sensor. The closest thing I have found is the one used in the Nintendo Wii where the remote tracks the distance of the IR LED lights....

Hello, I'm trying to construct an underwater detection system capable of detecting an object the size of a softball or larger when it enters the water. There...
