Bullet From M C Fitness and Spa Inc. - 6.1.2013

    Subject: Quantum Biofeedback Sensor

 

 

I am seeking a company to manufacture / supply a quantum biofeedback sensor similar to: http://quantum-life.blogspot.ca/2012/09/new-design-quantum-geo-harness-mark-11.html

 

The Quantum Geo Sensor, plugs into a devices audio port & converts the audible sound tones to an electro magnetic frequency and then projects these energetic tones or frequencies.

 

We would like the sensor to have only one pad, as thin as possible and the length of the cord (that plugs into an audio port) only about 6 inches in length, unless a pad with Bluetooth is available and price is reasonable.

 

We require a quantity of 1000 at first and a monthly order of 5,000 - 10,000 units.

 

If you are able to manufacture a quantum sensor please send a quote.

 

Sincerely,

    Subject: Sensor That Can Sense Chemical Changes in Sweat

 

Last month's issue of Scientific American describes a wrist band sensor that "senses" epileptic seizures by changes in galvanic skin response. Seizure guide dogs can be trained to forewarn of an epileptic seizure up to 45 minutes before the event. Could both approaches be sensing a change in sweat chemicals? Can you suggest an appropriate wearable sensor ?

 

Thanks.

    Subject: Help with MQ131 Semiconductor Sensor for Ozone

 

I am working on Air Pollution Monitoring and Measurement using MQ131 Semiconductor Sensor for Ozone, which we integrated into our Air Pollution Monitoring System. However, things seem not to be going pretty fine for me now. I am having great weakness transforming the measured data into ppm or ppb. I have read and studied the datasheet, but it doesn't seem to help me after all. Therefore, would you want to show me how to convert the present result into ppm/ppb or better, convert the result into ppm/ppb ?

Bullet From Mark Meilak  - 12.05.2011

    Subject: Level Sensors

 

At work, we have a lifting system which uses two pneumatic cylinders each controlled by a switch valve and supplied from a nitrogen gas cylinder. Since the system is very rudimental and the operator needs to operate careful both switch valves quasi simultaneously so that the lifting system rises/lowers in a leveled manner. My idea is to add some intelligence to the system by installing a level sensor which controls solenoid valves to operate the two cylinders so that the system rises/lowers always level. the operator just selects if he wants to rise or lower the system. Do you offer such sensor ?

Bullet From Ani Maximilian  - 8.05.2011

    Subject: Sensors for Project

 

Dear Sir/Madam,

 

We are working on a project in which the general OBJECTIVES are:

 

1) Gathering and measuring the environmental conditions in real time;

2) Take pictures or map the atmosphere which would help in determining our dirty the atmosphere is.

 

Based on the project objectives, I decided that the balloon payload needed to meet all the following design goals:

 

1. Accept and process GPS data (latitude, longitude, altitude, and time).

2. Operate multiple cameras.

3. Transmit activities performed, location, altitude, and temperature data.

4. Perform environmental measurements.

5. Record and transmission of data.

 

Sensors Needed:

 

1) CO Sensors*

2) NO Sensors*

3) Ozone O3 Sensors*

4) NOx Sensors*

5) NO2 sensors*

6) SO2 Sensors*

7) Air Quality Control Sensor  for detecting a wide range of gases, including NH3, NOx, benzene, smoke and CO2

8) Pressure Sensors

9) Nuclear Radiation Sensors 10). Particulate matter sensors.

 

* The statistics of concentrations of trace gases measured at a site using the conventional measuring instruments for these gases/pollutantin ppbv was 26.8±13.9 for O3, 0.7±1.8 for NO, 10.1±7.9 for NO2, 10.8± 8.8 for NOx, 2.2±3.6 for SO2 and 505±335 for CO. The annual mean O3 mixing ratio varied from 30.1±21.0 ppbv to 32.8±19.1 ppbv during 2004–2006. The annual mean NOx concentration were 14.5±14.0, 11.0±11.3 and 12.7±11.8 ppbv in 2004,2005, and 2006, respectively. The corresponding SO2 values were 5.9±10.0, 6.1±9.9 and 7.6±10.2 ppbv in 2004, 2005 and 2006, respectively, showing an increasing trend over the period from 2004 to 2006.

 

The flight program would be the most challenging part. In addition to coordinating the cameras, environmental measurements, GPS data processing, radio transmissions, and data-logging, the BS2 had to be programmed to react to any problems that might occur. This meant having a program that can react to problems like a power interruption (and BS2 reset), loss of GPS signal lock, GPS malfunction, and incorrect GPS data. It also needs to note whether it’s going up or down (which dictated how frequently it transmitted data), as well as the start of the descent (which can exceed 100 mph).

 

Therefore, we would want to ask if you can provide us with any useful Sensors that can be sensitive to the above parameters. Could you also give some suggestions on this project ?

 

Waiting forward to hearing from you.

Bullet From Nikunj Darji - 15.04.2010

    Subject: Wireless Temperature Monitoring System

 

We are manufacturing huge canisters for storage of spent nuclear fuel. For our canisters, we require a wireless temperature monitoring system. This system could be made of a thermocouple or RTD or thermistors, a wireless transmitter and probes to connect thermocouple or RTD or thermistors to the transmitter. Now the inside temperature of the canister is our main concern. We want to monitor the inside temperature of the canister with the frequency of one measurement per second to one measurement in 5 seconds. The canisters will be filled by water and the inside temperature will range from 0 0C to 250 0C. The external canister wall temperature will range from 700 0C to 800 0C. We are in the design phase and we are looking such a temperature monitoring system that could sense the temperature inside the canister and we could have it displayed on our computer at every second or maximum every five seconds. Now the possible set up could be thermocouples be placed inside the canister and connected to the wireless transmitter through extension wires. These wires shall be capable to do its intended function in the temperature range from 0 0C to 250 0C. The wireless transmitter will take these temperature readings and send it to the computer for monitoring. The thermocouple type we are trying to use is Type-T. So the transmitter shall be capable of getting connected to a Type-T thermocouple. We are going to have 4 thermocouples inside the canister.

 

So I would appreciate if you could provide me instrumentation that could satisfy this need and temperature requirements.
