The Ultium System supports “lossless” data recovery. The sensors continue to capture and store data (>8 hours of data) when communication is temporarily lost with the receiver. Once the record is completed, the data can be recovered later in two ways:
1. Real-time (online recovery) is initiated immediately after saving a recording.
2. Later recover (offline recovery) via the Import function is available after cancelling online data recovery (choosing “Recover later”)
Those two methods of data recovery are possible with all sensors in the Ultium line (Ultium EMG, Ultium Motion, and Core EMG), and are detailed below.
Online Data Recovery starts immediately after saving a measurment (using the Save & measure again or Save & View options) automatically. You know sensors are recovering data when you see the “Recovering, please wait…” message on the screen.
During this process, each sensor transmitswirelessly any packets of data that could not be transmitted in real time due to wireless interference or distance to the Ultium receiver. We recommend that the subject wearing the wireless sensors remains close to the Ultium receiver (2-5 m away) during data recovery.
Note: Online data recovery can be slow when data loss is extensive or intermittent for longer recordings. In these cases, we recommend following the process for Offline Data Recovery, as it works 20x faster than Online Data Recovery.
Offline Data Recovery is recommended when data loss is extensive or intermittent for long recordings. To recover data offline, follow the steps below:
Ensure the following connections between the sensors and the Ultium receiver:
- Each sensor must be in the charging station, and the charging station must be connected to the Ultium receiver.
- The Ultium receiver should be connected to the computer
- Each sensor should be turned on (LEDs blinking blue)
When you’re ready to recover data offline, use the Import function in MR and select the Import Offline Data Recovery option from the Database.
