Compilation on windows

Sat, 14 Mar 2015 13:52:39 +0000

According to the instructions you need this file: http://people.gnome.org/~amorales/gstreamer-sdk.7z

which doesn't exist

I assume it's the compiled gstreamer sdk but the downloadable version has files missing and cerbero can't fully compile the sdk with "cerbero-uninstall package gstreamer-sdk" (it breaks after compilatin somewhere during wix)

Any help?

Using different encoder

Wed, 12 Nov 2014 16:58:55 +0000

Hi
I have an old MuscleLab encoder that I'd like to use instead of the encoder you sell. Since it also is a 5V quadrature encoder chronojump can see the signal. The problem is that the wire drum is of a different size and the sensor most likely have a different number of pulses/revolution.

I would like a setting that allows me to scale the encoder signal according to drum size and pulses/revolution. Is that possible to implement into a future version of the software?

Inertial Moment en Polea Cónica

Mon, 13 Oct 2014 20:31:41 +0000

Buenas noches,

Me acabo de hacer con un encoder de eje, el cual ha sido acoplado a una polea cónica, hasta ahí todo bien. La polea tienen 4 alturas donde se inserta la cuerda en diferentes partes del cono y 10 pesos.

Cuando inicio el proceso para trabajar con el encoder me encuentro con algunas dudas:

En el apartado "Selección de encoder" al escoger el "Rotary axis- inertial machine" aparece el momento de inercia (habitualmente salen 80 kg) . De ahí he intentado hacer el cálculo del IM y no me sale nada. He visto como lo explicais en el vídeo y entiendo que hay cosas que aún no se pueden establecer con demasiada precisión. Me gustaría saber si habéis avanzado algo respecto a este apartado o si me podéis dar alguna pauta en concreto. La opción que había pensado era mantener el IM e ir introduciendo pesos y cargas e ir testando los resultados del deportista.

En el apartado "extra mass" entiendo que en ese caso trabajamos en 0.

Muchas gracias

Blank graph

Fri, 29 Aug 2014 14:13:16 +0000

Hi, when i analyze and select more than one session and mark only one person, i receive a blank screen in the graph...(but works correctly if i mark all the people) Is it normal?

Encoder changes

Signal is called "set", and curve "repetition
On encoder, when capture is done, best repetition is saved automatically (following criteria of best mean power on concentric phase). Can be changed on preferences to save all or save none of the repetitions.
Changed Neuromuscular Profile, now uses ecc-con phase (not ecc-con-ecc-con as before), and can be used on current set and on saved repetitions. Only needs three jumps to work.
Inertia moment calculation now calculates also the inertia moment of the different weights attached.

Jumps, runs changes

On capture, jumps, runs result is now show on bold to distinguish from other numbers
When executing a test, timer on screen is always ok. Before results where ok, but realtime chronometer on the screen on contacts execution had a bit of lag. Now is solved.
Added split times on interval runs results
Added new method to calcule DjPower on jumps (added to results and to statistics)
Added RSA RAST test
Elasticity Index, Arms Using Index, IRna and IRa now calculated by default using heights (not flight times). User can change it on preferences and leave it as before if desired.
RSA tests cannot be simulated now (can only be done using Chronopic)
When Chronopic gets disconnected, next test is managed as simulated without crashing the software

Other changes

On preferences, translatable graphs option affects now on encoder and on the rest of the tests (before was only on encoder)
Better Chronopic-Firmwarecord, now it's easy to access to the firmwares and the problems on loading a firmware are gone.
Added Troubleshooting guide (See manual folder)
Updated manual
Press 1,2,3,4 on start to select mode: Jumps, Runs, Encoder or Other
Updated Spanish and Czech translations
Minor fixes

Chronojump 1.4.4

Tue, 17 Jun 2014 14:33:20 +0000

Chronojump 1.4.4 has been published! (2014-June-17)

Backup database:
Important: if you are an encoder user, we recommend you to backup the full database before update. Many improvements have been done on signals / curves tables. If there's any problem with update and you made the backup, it will be easy to fix. Proceed as follows:

Before installing new version, open Chronojump 1.4.3
Session menu / preferences / Open database folder
go up in your file manager one time and you will see the folders: "database", "encoder" and "multimedia". Copy the three folders to another place (eg. pendrive)

Download here:

Windows: http://ftp.gnome.org/pub/GNOME/binaries/...-1.4.4.exe
MacOSX: http://forum.chronojump.org/showthread.php?tid=348
Linux: http://forum.chronojump.org/showthread.php?tid=977

Major improvements

Lots of improvements on graphical interface. The biggest is at start: 4 modes are shown:
Jumps, Runs, Power, Other. Shown in nice graphs. User can switch between modes
Now Signals are more connected to curves:
- Same curve cannot be saved two times
- Checkboxes on Capture tab to easy save / delete curves
- Display saved curves on barplot at capture tab
- Deleting a signal deletes it's related curves
Encoder graphs are four times faster now
Copy database can also copy encoder data and multimedia (photos and videos)

Minor improvements

Contacts
- Added DJa graph
- IUB renamed "Arms Use Index"
- Contacts stats graph dialog can be maximized
Encoder
- Mean power is shown on curve selection
- Load signal/curve shows now the laterality "R/L"
- Encoder Load signal works accepts on 'enter' or double click on treeview
- Encoder analysis cross shows line fit. Predicts maximum power and the load needed for this power. Writes also the function, R^2, Adjusted R^2 and p-value
- Shown accuracy warning on conical machines. Also message: "Start fully extended on inertial machines" is more visible now.
- Added Neuromuscular profile guidelines
- Encoder bells (feedback) moved to main window
- Export session (.csv) says now: "Encoder data is not exported"
- Analyze Cross variables without overlapping numbers. Data is shown nicely now
- Preferences: "no translate graphs" on Preferences / other (partial for fix translation of graphs on Greek)
Other
- Easier chronopic connection. Don't need to open Chronopic window and there open another window. All is done in the same window.
- All windows can be closed fast pressing ESC button (all but main Window)
- Better message on chronopic-firmwarecord
- Updated English manual: Added info on importing persons from CSV

Fixed bugs

Contacts
- Fixed error on jumps, runs selection on new GUI since 1.4.2. This affected to user created tests and RSA tests.
- Fixed random crash on cancelling contact tests (jumps, runs)
- Improvements on sensitivity on cancel finish contact events. Sometimes when cancel an event that has not started yet (user is outside platform and should be inside), window was irresponsive
- Fixed Shetty CMJ power formula calculation
Encoder
- Fixed error in weight display in curves analyze table
- Fixed problem on button encoder_analyze that was active when no curves or person where selected
- Delete signals / curves from ask confirmation if askDeleteion is selected on preferences
- Fixed encoder: jumps height when a jump is badly executed with a force < 0 at the beginning
- Fixed error that says: "Encoder connected" when it was not connected yet
- Fixed crash when USB cable is disconnecting while receiving data
- Encoder Analyze. Fixed crash on sqlite open/close multiple times in a foreach
- Neuromuscular profile is working again
Other
- Now on Linux and on MacOSX, Chronojump cannot be opened two times (two instances at the same time)
- EncoderCaptureOptions opened/closed fast on start. Now is not shown

Pending bugs

Camera is not working on MacOSX.

Updated Czech translation.
