Acceleration measurement and determination of therelevantfrequency,the acceleration and the amplitude of theoscillationExplanation ofthe buttons arranged on top of the screenCONTI:Continuousmeasurement 5 SEC: Fixed measurement duration of 5sec,then STOPautomatically STOP: Stop of measurement, the last5seconds aredisplayed -: In stop mode, move zoom window(1.28sec)to the left,only for PRO version +: In stop mode, movezoom window(1.28sec) tothe right, only for PRO version There aresevenfigures below thebuttons. Upper figure "Currentaccelerationvalues": Theaccelerations values are displayed. Thesamplingfrequency of mostsmartphones is 50 Hz. If the actualsamplingfrequency deviates by ±1 Hz, then the actual samplingfrequencyappears (flashing).Different times must then becorrectedaccordingly. The numericallydisplayed measured valuesarecorrected automatically. During a swipeaction "from bottom lefttotop right", the APP goes into adiagnostic mode. Then theactualsampling frequency, the standarddeviation of thesamplingfrequency and an internal counter appear.Underneathfigure"Accelerations over time": It shows theaccelerations curveof thelast 5 seconds. After pressing STOP, awindow of 1.28 sec ismarked(vertical black bars). in PRO version:the window can bemoved by±, after a double-tap on the figure itappears twice aslarge,after another double-tip it is resized again.Swipe up, swipedownto change the scaling. Underneath figure"Largest of thethreeacceleration components curve": It shows theaccelerationcomponentwith the maximum acceleration change. The zoomwindowisrepresented by 1.28 sec. It is particularlysuitableforoscillation frequencies from 1 Hz to 15 Hz. The moresinusoidalthetime signal, the more secure are the determinedvalues.Indiagnostic mode, trigger points and sineapproximationsarevisible. In PRO version: after a double tip on thefigureitappears twice as large, after another double-tip itisresizedagain. Swipe up, swipe down to change thescaling.Underneathfigure "Numerical evaluation from the timesignal":Hereevaluations from the time domain are displayednumerically. Inthediagnostic mode, the number of detectedvibrations aredisplayed.Sx is their standard deviation. The largern and smallerSx, thesafer the values determined. The accelerationamplitudealsospecifies a standard deviation. The calculation isdone withtheleast square method. Underneath figure "FFT-writingoftheacceleration over time": Here, a plot of theaccelerationspectrumover time is shown. Shown are the last 5seconds. The zoomwindowis marked. In PRO version: after a doubletip on the figureitappears twice as large, after another double-tipit isresizedagain. Swipe up, swipe down to change theintensityscale.Underneath figure "FFT spectrum of the zoom window":It showstheFFT spectrum within the zoom window. The black curveistheresulting acceleration. In PRO version: after a double tiponthefigure it appears twice as large, after another double-tipitisresized again. Swipe up, swipe down to changethescaling.Underneath figure "FFT, numeric": It is the numericoutputof theFFT spectrum within the zoom window. The maximum of theFFTisindicated by a cross. Frequency, Amplitude andmaximumaccelerationvalues are shown.
ADSB Receiver Pro 4.8.0
The leading ADSB Receiver for Android!! ** Please note: -YOUNEEDADDITIONAL HARDWARE TO USE THIS APP. -Disable batteryoptimizationif run in background. This app enables your device toreceive liveADSB data (978 MHz UAT and 1090 MHz ES). All you needis asupported USB dongle and an OTG cable, both available fromvarioussources on the internet for less than $20.-. Nosubscriptionrequired! Follow this link for moredetails:http://hiz.ch/index.php/home/adsb-receiver Use this app toprovidelive ADSB data to Avare! All data received (traffic, Nexradweatherand standard reports like METAR, TAF, PIREP, WINDS, ...)will bemade available automatically, once Avare has been detected.(Makesure to enable "Use ADSB Weather" in Avare.) Download Avarehere,it'sfree:https://play.google.com/store/apps/details?id=com.ds.avare Youcanalso forward the data to most GDL90 compatible apps likeiFlyGPS,FltPlanGo, DroidEFB, ... USAGE Attach a supported USBdongle toyour Android device by using an OnTheGo (OTG)cable/adapter. Makesure your device supports OTG! Start the app andallow access tothe dongle. You should see packages flowing inquickly, dependingon your location. HARDWARE Supported tuners:Rafael Micro R820T andR820T2.
