  • Repetitions are automatically detected:
    • … plot according to minimum force on (not elastic) / minimum displacement (elastic).
    • Force/displacement repetition criteria is defined on exercise creation and have a default on preferences window.
    • can be zoomed clicking with mouse.
    • Repetition number is exported with the rest of the data.
  • All the force sensor mode now uses database
    • All the old data is automatically imported to database to be managed properly.
    • The management of the data is much better now and solves problems like the change of the name of the person who performed the test.
    • Tests can be loaded, change the author, deleted, removed, change any params of the exercise or capture mode, and recalculated to have new results (and update on them on database).
    • There’s a management of deleted exercises to not delete the tests with them (like on encoder).
    • Session load window shows force sensor tests.
    • Show all persons tests window shows force sensor tests.

  • New feature: capture with scroll (default and configurable on preferences). This mode it also implements the feedback rectangle.
  • Can capture using absolute or inverted values (and can be recalculated).
  • Several changes on exercises:
    • Depending on exercise configuration it can be shown resultant force or raw force detected by the sensor.
    • Exercises now use percent of body weight, so results in N will change if you select that exercise option.
    • Exercises have new option: tare before capture that makes a tare at the beginning of each capture. Useful for exercises like hamstring force on leg at some height and fixed to a bar with the strain gauge. In this exercise, the automatic tare will remove the weight of the leg.
  • Added laterality buttons.
  • Can save comment.
  • Feedback rectangle shown transparent.
  • on RFD automatic graph, it is displayed mean error of the model, exercise name and date.
  • On general analysis, sliders and buttons have changed and all data is shown on the interface (and not in the graph potentially hiding the lines).

  • At analyze has AB, first/last buttons (like on encoder).
  • On preferences force sensor it can be selected how much seconds will display the capture area (default 10 seconds).
  • Labels Max/Current/Min at right and better formatted.
  • Force capture drawingarea can be resized at anytime and graph is redrawn.
  • Capture graph: Better vertical space while capturing.
  • Force sensor capture graph is ok now for really low forces.
  • ForceSensor tare/calibrate do not need to check for sensor 0.4, much faster now on this firmware update. Also 0.4 makes a tare 5 times faster.
  • Graphs line width can be changed on preferences (nice for big screens or bad viewing conditions).
  • Force sensor can read triggers on capture (not display them yet).
  • Force sensor connect is more robust.
  • Show label at checkVersion (of the firmware) from menu.

  • Saving repetitions has two new modes “bestn”, “bestn consecutive”, where n repetitions can be saved automatically.
  • Saving repetitions can be done clicking them on the bars graph.
  • On inertial, end capture also when 2*inactivity endTime since last phase. This helps to automatically end the inertial capture when inertial machine is still slowly rolling.
  • Improvements on loss calculation
    • Loss is always calculated on concentric.
    • Loss is calculated always from best repetition to the end of the set.
    • Loss is displayed on graph with info and an arrow.
    • Loss does not use last repetition if it’s range of movement is low (range smaller than 70% of range of the best repetition).
  • Encoder feedback can be only eccentric or concentric phase. Unwanted phase is shown as gray bars.
  • Eccentric overload drawn with green arrow (if achieved).
  • Historical feedback can be also on mean speed and mean force.
  • Added RPD calculation.

  • On analyze current session, at select repetitions is shown also mean speed and mean force (it was shown only mean power).
  • New method to display the bars, should be faster specially after 1st capture.
  • On analyze / superpose graph shown end of propulsive phase.
  • Encoder exercises can be renamed.
  • Eccentric ground phase starts when force >= 0 like in paint (not >= weight).
  • Added ‘e’ or ‘c’ on ecS set/repetition export to csv.
  • Fixed encoder inertial feedback historical.
  • Fixed labels of repetitions on capture bars when showNBars is active on preferences.
  • Plot bars title adjust to window size.
