  1. *Applicable to all length configurations
  2. Slack angle, functional range, and full loading range are consistent for all length configurations (U1L1, U4L5, U7L8, U10L12). Exoskeleton balance angle, unloading range, and partial loading range vary by spring (A-I) and length settings (OOR, outside operating range; N/A, not applicable)
