Chronojump software: 1.5.2 (2015 Jul 25)

  Main changes

• All tests in the software (jump, runs, other tests) have an interface similar to encoder. Selection of tests and options is on the top and there are only two tabs: Capture and Analysis. Results tab (from previous versions) it’s found now inside of Capture (select it at center-right of the screen “Show table”).
• Added language change option in preferences (for users who had problems with the language of Chronojump).
• Safer autodetection of Chronopic.

  Minor changes

General:

• If no session, two big buttons are shown on the left (new session / open session).
• Person win is much easier to use now.
• Improved interface for tablets with bigger buttons and a person select window (This tables have to run on Windows, Linux or MacOSX).
• Safer load session, export, report (with less database calls). Some users had problems with too much Open/close database actions.
• Safer open of a CSV (spreadsheet) if it’s already opened by other software.

Jumps:

• Fixed not display of calculation of potency and stiffness on interval jumps after the jump.

Encoder:

• Improved power calculation on inertial modes (now eccentric values are higher than in previous versions).
• Added forces on encoder analyze table.
• Created configuration file for automatic configuration encoder and inertia machine (inertia machine vendors can send his file to their clients).
• GUI improved on encoder main buttons: calcule, recalculate, …
• Moved encoder “export current set” to menu.
• Some encoder methods are more robust.
• Fixed smoothings on eccentric-concentric repetititions. Some of them had a smoothing too low.

Chronojump software: 1.5.1 (2015 May 29)

  Global changes

• Encoder is autodetected in all systems
• Normal Chronopic (jumps / runs) is autodetected on MacOSX and Linux (Windows will be solved on next version)
• Fixed crash at load session when checkboxes are clicked

  Encoder

Faster:

• Encoder processes are much faster now (processes leave opened)
• After capture, treeview and bars are not erased. Don’t need to wait to be created the final set graph. This is much faster.

Graphical interface:

• New layout of encoder capture (video and serie on the right)
• Inertia extra weights selectable from main gui
• Adaptative displayed height on capture
• Encoder configuration window is better now
• Improved encoder inertial images

New features:

• Encoder capture tab show force on realtime plot and works with bells
• Encoder configuration gets stored on database for having the same configuration next time Chronojump is opened
• Added two inertial modes: lateral and mov pulley
• Encoder video filename is shown and folder can be opened
• Some graphs use inertia instead of mass if some repetitions are inertial
• On load set, current set row is selected
• On side compare speed, power, … 0 horizontal line is shown
• On paint eccentric show also min speed, min power
• Barplot eccentric shows diagonal -45 lines for eccentric

Better calculations:

• Calculations (like mean power) are the same now on realtime capture and on other calculations because calculation methods have been unified
• Safer calcule repetitons on capture (shorter are discarded, this fixes some problems in small micromovements or cable distensions while doing the movement)
• Better way to auto-calculate the smoothings on eccentric using power instead of speed
• Eccentric speed is shown in absolute value

Bugs fixed:

• Fixed 1.5.0 bug: cancel or delete signal makes bars disappear until cj is closed
• Fixes on encoder recalculate and previously saved repetitions (no more meanPower 0)
• Fixed problem (Chronojump crashed) with weight (with decimals) on analyze
• Fixed bad smoothing was assigned to some repetitions
• Fixed force and power in inclinated planes
• Fixed mass on LINEARONPLANEWEIGHTDIFFANGLE.
• Now Jump height calculation is only in linear and inverted modes
• Fixed delete session now deletes all encoder and videos stuff

  System specific

MacOSX specific:

• Error log (and ping) can be sent from MacOSX
• Fixed splashWin (initial small window) permanent on mac sometimes

Raspberry Pi specific:

• Run maximized by default
• On raspberry not camera (personal photos) cannot be done
• Extra mass controls for raspberry

  Translations

• Added Italian translation
• Updated Czech, Romanian translations

Chronojump software: 1.5.0 (2015 March 17)

Update 8 April: We published an update for MacOSX fixing a screen that gets hanged on start. Now the official 1.5.0 download for Mac has this update and other improvements that will be on version .1.

  Main changes

Global:

• Photos and video work now on MacOSX.
• First startup of the software (creation of database) now is much faster (6 times aprox.)
• In order to detect and fix bugs fast, a log is always saved and can be sended easily to us (just press a button if software crashed).On MacOSX it has been deactivated temporarily, but users can send it opening ‘preferences’ window, then clicking on ‘open logs folder’ and sending the files by email.
• Improved start on MacOSX. On some systems crashes sometimes.
• When one or more peresons are loaded, now the ‘modify person’ window does not appear. Then loading is faster.

Encoder:

• New capture method. Faster and works in all systems (old method didn’t work on XP and has some problems on MacOSX).
• On capture now realtime data on inertial machines is dispayed. Repetitions are shown as concentric or concentric-eccentric.But, after capture, repetitions will be shown as concentric or ecc-con. This happens because all the software parts are not prepared yet to manage the con-ecc repetitions.
• Results on realtime capture are now very similar to the results obtained at the end of capture.
• Inertial machines with too much friction can use now the inertial momentum calculation method because now it needs only half of the oscillations than before.
• During the capture. now the force can be shown but only numerical. Graphical realtime force capture will be done in next version.
• Video record and play is done in a bigger and centered area of main window.
• At the ‘analyze’ tab, ‘cross variables’ button, now there’s a different icon for eccentric-concentric phases, and also laterality. Laterality is shown also in other graphs.
• If there’s a problem on capture, software will not crash now. User has to be able to cancel the analyze process.
• Fixed bug exporting on encoder. It didn’t worked on some systems.

Jumps and runs:

• Added stiffness calculation on jumps.
• Fixed a problem on performing interval runs when only on track has been detected.
• Fixed bug with the ‘time’ label at the end of some jumps and runs.

  Minor changes

Encoder:

• Better colors for differentiate ecc-con phases.
• Is USB cable is disconnected while capture with encoder, software detects it and alerts the user. This works fine on Linux and MacOSX, but the fix is still pending on Windows.
• On the ecc-con capture, first repetition is discarded if it’s concentric.
• While capturing now is not possible to press buttons like weight, laterality, … changing this button on capture produces problems in previous version.
• Fixed some bugs on loosing information on serie recalculation (video got lost). All the lost data has been recuperated.
• Fixed a problem on saving 1RM when it couldn’t be calculated.
• Fixed problem on 1RM calculation of different exercises at the same time. Now it’s not allowed to calculate 1RM of different exercies together.
• Fixed small problem on the person displacement on the axis rotary encoder at inertial machines.
• More precision on inertia momentum calculation because now two decimals are allowed in machine diameters.

Jumps and runs:

• On multijumps capture ‘height’ is shown and can be used as feedback (bells).
• If USB is disconnected at the middle of test, test can be aborted (on previous versions software started an infinite bucle).
• Deleted “maximum” jump, now “Free” jumps is used.
• Fixed power calculation on Drop Jump (extra weight was not used in the formula).
• Now multijumps show also power.
• Fixed Chronopic connection problem on multijumps or interval runs tabs.
• Improvements on jumps and runs cancel. Now software performs better after a cancelled test.
• Exporting reactive jumps show more data now.

Others:

• Fixed a random problem on Chronopic detection that makes Chronopic window close suddenly.
