using tags
Tags are small objects that store the lock command. When
morph lock
comes close to a tag,
morph lock
wirelessly reads the tag and interrupts EMG
signals to the hand; the prosthesis becomes frozen in its current position.
To unlock the prosthesis, the user can approach any lock tag and the hand
will again respond to EMG. The user may find this tag useful when holding
objects (i.e. beverages) to maintain a secure grip. In the locked state, the user
does not have to worry about accidentally opening or closing the hand.
The tags do not use batteries and therefore do not require periodic
maintenance or replacement. Several tags are included with your
morph lock
shipment. The tags are already programmed and ready to use.
TAG SIZES
You will notice that your tags come in different sizes. Larger tags have a
longer range (1-3”) than smaller tags (<1”).
TAG VIBRATION PATTERNS
Everytime it detects a tag,
morph lock
vibrates to notify the user that it has
read the tag.
morph lock
creates different vibration patterns depending on
the mode it enters. This feedback can be very helpful for the user to know
the status of the prosthesis. The different vibration patterns are summarized
in the table below:
Condition
Vibration Pattern
Prosthesis locked
Two quick vibrations
Prosthesis unlocked
One short vibration
Note:
morph lock
will also vibrate when it is powered on. Allow the device 5
seconds after power on before attempting to control the prosthesis.
