SATRA PPE

door | dec 30, 2011 | Apps

Ensuring personal protective equipment (PPE) is fit for purpose can be a daunting process. There are many technical and legal requirements that must be met before PPE can be brought to market in Europe. This application from SATRA is an essential guide through the maze of standards and legislation which faces manufacturers, distributors, retailers and those who purchase and/or wear personal protective equipment.
The SATRA PPE Survival Guide app will give you the background information you require to have a basic understanding of the tests that need to be carried out to meet specific international standards. It will also answer questions about EU regulations, CE marking and the different levels of PPE design.
The app also contains a PPE image gallery, and a live news feed so you can easily view the latest PPE and other news from SATRA and connected industries wherever you are in the world.

Radiation Calculator

door | dec 29, 2011 | Apps

The Radiation Calculator was developed to help you learn about the many types of imaging studies that use radiation and also track the amount of your radiation exposure. Please Note: This app is NOT a substitute for medical advice. Talk with your doctor about the risks and benefits of any imaging study, whether there are any other alternatives, and if you have questions or concerns about your radiation exposure.
By entering your age and information about your imaging test history, you can calculate your estimated radiation exposure over time and compare the amount of radiation you have received with an average patient within the age range you entered. You can also compare this amount to radiation totals received through natural and other sources.
The Radiation Calculator has many great features:
* Explanation of imaging studies and estimated radiation dose
* Easy-to-use calculator to determine your estimated radiation exposure from imaging studies
* Customizable radiation exposure report that can be saved to share with your doctor
* Comparison of estimated radiation dose from imaging studies and other sources of radiation

Vibrometer

door | dec 28, 2011 | Apps

Vibrometer is a tool for measuring vibration.
With Vibrometer you can challenge your friends and win if your body is more motionless than the bodies of the other players.
Stretch the arms forward, keeping the device in one hand and press the “START” … keep the device as motionless as possible (from START until TIMEOUT).
Who consumes less energy wins the challenge.
Vibrometer can also be used as a tool for measuring vibration by activating the “recording”… the tool will automatically calculate the minimum and maximum vibration along the axes x,y,z, the energy consumed and record the instantaneous values of the accelerations. These data will be saved for later use. Acceleration data recorded can also be displayed graphically.
Have fun!
Functions:
– Measuring vibration
– Counter energy consumed
– Recording function
– Calculation of minimum and maximum vibration along the axes x, y, z
– Multiplayer game (wins the challenge, the player who makes the device vibrate less)
– Chart of accelerations recorded along the axes x,y,z
– Acceleration diagram zoom
– Saving diagrams of accelerations in the “Photo Album” of the device
– Diagrams of accelerations can be sent with e-mails
 

Psychrometer

door | dec 27, 2011 | Apps

Psychrometer is an application to calculate the various properties of moist air. You can easily calculate values such as dew point temperature and relative humidity. To calculate the water vapor pressure, we use the Tetens(1930) equation. 
Features:
– Intuitive operation of slider.
– Temperature units, Celsius (℃) and Fahrenheit (℉).
– Volumetric humidity units, (g/m³) and (gr/ft³).
– Specific humidity units, (g/kg) and (gr/lb).
– Pressure units, (hPa), (mmHg) and (inHg).
– Enthalpy units, (kJ/kg) and (Btu/lb) .
– Specific volume units, (m³/kg) and (ft³/lb).
– There are two types of psychrometers, natural and forced ventilation.
The value can be computed:
Relative humidity, Discomfort index, Volumetric humidity, Specific humidity, Vapor pressure, Saturation vapor pressure, Dew point temperature, Enthalpy, Specific volume.
 

SPL

door | dec 26, 2011 | Apps

SPL is a professional-grade digital sound level meter (decibel meter) for your iPhone or iPod touch. It includes all of the modes, filters, and features that you would expect from a professional ANSI or IEC Sound Level Meter. All filters and averaging modes meet or exceed the criteria for ANSI Type 1 or better. SPL is created from the same team who brought you the Audio Toolbox and ATB Plus.
*** IMPORTANT NOTE ***
Do Not buy this app if you own AudioTools — buy it from WITHIN AudioTools.
If you are planning on buying iAudioInterface, you should instead buy our AudioTools suite of apps instead of this app, and buy this app from within AudioTools. It is priced lower in AudioTools.
*** Important Note for 3Gs Owners ****
The 3Gs has a much steeper low-frequency roll-off filter than previous models. This release detects the 3Gs model and corrects this as much as possible, given the extreme loss of low frequencies. See our web site for more information.
Graphics — There are three user-selectable options for the front panel. These include aluminum, dark metal, and plain. The dark metal option, with blue digits, is designed to work best in dark environments. Use aluminum or plain in daylight. To change the skin, just tap the small “i” icon in the bar on the top of the screen.
Store Result — We now have provided 9 memory slots for storing results. The dB SPL level, mode, weighting, time, date, and a description are all stored. Also, for non-Leq modes, the max and relative are stored, and for Leq, the Max and Leq time.
The iPhone 3G has the best microphone frequency response. SPL will work on the first generation iPhone, but without the same accuracy. You can also use SPL with our calibrated iPhone measurement mic, see below for details.
If you have an iPod Touch 2nd Generation, SPL will work, but you need to use an external mic, like the headphones / mic that is included with the iPhone.
The screen flips if you turn the phone upside down, so that you can point the built-in iPhone mic directly at the sound source.
*** Modes: Slow, Fast, Impulse, Peak, and Leq.
*** Filters: A and C weighting, and 10 octave band filters.
*** Includes a resettable Max field to track the highest reading.
*** Includes a reference field (except in Leq mode) so that you can set a reference level and do seat-to-seat comparisons.
The SPL meter can be fully calibrated. It comes preset with the calibration for a typical iPhone 3G. Most iPhone model 3G will be within a few dB of this reading. If you have access, even temporarily, to a calibrated sound level meter, just use the calibration field on the flipside to match the meter, and you will be accurately calibrated.
Also, see our other professional-grade audio apps: AudioTools, our premier suite of professional-caliber audio and acoustics test apps, Speaker Pop, to test speaker polarity, and RTA, a real-time analyzer for the iPhone.
And, we will soon be releasing a calibrated, accurate measurement microphone as part of our iAudioInterface system for the iPhone and iPod touch. This will allow measuring a range from approximately 30 dB SPL to 130 dB SPL. Each mic will include a calibration factor that you will enter into the SPL app for calibrated measurements. This mic will also work with Speaker Pop, our speaker polarity tester, FFT, RTA, ETC, and other acoustical measurement apps in our AudioTools app that we will be releasing soon.
 

 

NOTE: I have enabled the “buy for first gen Touch option”, but be advised that you have to arrange your own input via the dock connector. This model does not support the headset mic nor does it have an internal mic.
Now includes an iPhone internal mic compensation filter, to cancel out the low-frequency roll-off present in the iPhone.
