Dexterit-E 3.10.1  May 2023
Dexterit-E 3.10.1 is primarily a minor improvement and bug fix release; it also contains one important bug fix for future hardware updates, but which does not affect any existing customer installations.

Possible Encoder Drift Error on Startup

(DEX-4735) This is an issue that only affects a subset of newer Kinarm robots with secondary encoders when used with the recently released Dexterit-E computer PN 15012; the issue manifests as an encoder drift error intermittently being reported on system startup. Currently there are no Kinarm Labs in the field with this configuration. Customers with Kinarm Labs purchased since 2016 that upgrade to a Dexterit-E PN 15012 computer should be sure to install at least Dexterit-E version 3.10.1.

Dexterit-E & Dexterit-E Explorer 3.10 released 24-Feb-23

After a year and a half of hard work, the design and development teams at Kinarm are pleased to simultaneously release:
  • Dexterit-E™ 3.10.0; and

Some of the more noteworthy changes in Dexterit-E & Explorer 3.10.0 include:
  • For Kinarm Standard Tests
    • New Test: Paired Associates Learning
    • Video instructions
    • Updated Analysis for Arm Posture Perturbation: per our product advisory, the rare event in the task has been corrected.
    • Updated analysis of VGR & RVGR:
      • To better handle rare instances where Movement Time could look worse as a subject is improving.
      • To avoid rare instances of very large values for Path Length Ratio.
      • Updated RVGR’s Direction Errors parameter to be scaled by the number of completed trials when calculating Z-scores (i.e., for partial exams).
    • Enhanced Analysis Export for more efficient (re)analysis of database records
  • Task Development: Exoskeleton users can now define targets using the global frame of reference
  • Kinarm Gaze-Tracker now uses an efficient 5-point calibration
