Operating Modes - be bionic steeper Technical Manual

5.6 Operating Modes

There are six modes. These are selected from the
highlighted box, along with the appropriate control
option.
Note: Grip change will generate a bleep and / or
vibration if this feature is enabled.
Mode 0
Control Strategy – Single Site Threshold
-To OPEN hand – apply signal
-To CLOSE hand – remove signal
Grip Patterns
Thumb Opposed – up to three grip patterns
Thumb Non-Opposed - up to two grip patterns
Mode 1
Control Strategy – Single Site Threshold
-To OPEN hand – apply a short burst signal
-To CLOSE hand – apply a sustained signal
-To switch between default grip and alternative grip –
apply a further OPEN signal within variable time (up to
two seconds) of the hand fully opening.
Grip Patterns
Thumb Opposed – up to four grip patterns
Thumb Non-opposed - up to four grip patterns
Mode 2
Control Strategy – Single Site Proportional
-To OPEN hand – apply a quick rising stimulus
-To CLOSE hand – apply a slow rising stimulus
-To switch between default grip and alternative grip –
apply a further OPEN signal within variable time (up to
two seconds) of the hand fully opening.
Grip Patterns
Thumb Opposed - up to four grip patterns
Thumb Non-Opposed - up to four grip patterns

Mode 3
Control Strategy – Single Site Proportional / Threshold
Alternating
-To OPEN hand – the first signal will OPEN the hand;
a configurable delay of 50ms to 2.0s will allow repeat
OPENS if required.
-To CLOSE hand – a signal applied outside of the delay
will CLOSE the hand; a configurable delay of 50ms to
2.0s will allow repeat CLOSES if required.
-To switch between default grip and alternative grip –
apply a further OPEN signal within variable time (up to
two seconds) of the hand fully opening.
Grip Patterns
Thumb Opposed - up to four grip patterns
Thumb Non-Opposed - up to four grip patterns
Mode 4
Control Strategy – Dual Site Proportional / Threshold
OPEN OPEN
-To OPEN hand – apply signal from OPEN electrode
-To CLOSE hand – apply signal from CLOSE electrode
-To switch between default grip and alternative grip –
apply a further OPEN signal within variable time (up to
two seconds) of the hand fully opening.
Grip Patterns
Thumb Opposed – up to four grip patterns
Thumb Non-opposed – up to four grip patterns
Mode 5
Control Strategy – Dual Site Proportional / Threshold
Co-contract
-To OPEN hand – apply signal from OPEN electrode
-To CLOSE hand – apply signal from CLOSE electrode
-To switch between default grip and alternative grip –
apply a co-contraction signal
Grip Patterns
Thumb Opposed – up to four grip patterns
Thumb Non-Opposed – up to four grip patterns
In modes 4 and 5 the hand operate on the first signal
that exceeds the ON THRESHOLD. If an opposing
signal is received and exceeds the initial signal by a
pre-set ammount then the larger signal will become
the dominant signal.
Please note: Where more than one grip pattern is
available, the practitioner can select the default and
alternative grips for both the primary and secondary
grip patterns using bebalance programming software.
Pressing the program switch on the back of the hand
allows the user to alternate between the primary and
secondary set of grip patterns.
The hand will be delivered pre-set to Mode 4 with
default values set to provide an operational hand
straight out of the box. Therefore, configuration via
bebalance may not be essential pre-fitting
