Intended Use
2
The Zeus Congurator is designed to be used solely by clinicians certied by
Aether Biomedical Patients, as the users of the prosthesis, are not allowed to
make any changes to it via this software.
The software provided by Aether Biomedical is designed exclusively for the
Zeus hand conguration.
The Zeus Congurator is intended to be used to congure the Zeus hand and
customize it for the user. Additionally, the software also provides the required
tools to service and repair the Zeus hand.

Zeus Hand Congurator - Web Application Instructions 7
The Zeus hand comes out of the box in its primary conguration - the resting
non-opposed grip.
Zeus typically utilizes typically two sensors that detect and amplify raw EMG
signals from the skin that come from muscle movements. To create those
signals, the patient has to contract their muscles.
Depending on the dierent levels of amputation, there are specic types of
signals to change the grips. Co-contraction can be made by the majority of
the users and provides a very reliable control of the prosthesis. Therefore it
was chosen as the default option.

With the Zeus Congurator, it is possible to change the control settings - Input
options, Input sites, Control strategy, Grip switching modes, Soft-grip settings,
Ignore EMG spikes settings and Autograsp settings.
There are a number of grips which the user can choose. Co-contraction
(default option) allows the user to switch between grips.
The clinician can view the user’s muscle contractions in real-time graphs and
adjust the activation levels/thresholds.
REMEMBER: Changes should be made to the settings that are not optimal
for the user, the previous settings can be restored simply by loading a previous
conguration from the database.

Bluetooth Low Energy Connection
5
The Zeus hand uses BLE (Bluetooth Low Energy) to communicate with the Zeus
Congurator.
To start conguring the Zeus, it is necessary to turn on the Bluetooth on your
computer device.
If your device does not come with a Bluetooth modem inbuilt, you can use
a BLE dongle. You will need to install its drivers according to the provider’s
instructions.

The process of scanning for the prosthetic devices will begin. Your device
should show up on the popup screen. The scanning process might take up to
several seconds. If your device does not appear on the list, make sure that the
battery of the prosthesis is turned on.
Select the device and click on the Pair button.
The application should now connect with the Zeus hand. It will retrieve its
settings and display them on the screen. If you cannot connect to the
prosthesis check if you selected the correct prosthesis and turn its battery o
and on.

In the upper right corner of the Settings Area you will nd the Pairing mode /
Sequential mode switch. Changing this switch will select the corresponding
control mode setting in the prosthesis.
Choosing the control mode changes the displayed graphics in the Settings
Area. There you can select the order in which the grips will be accessed in each
of the control modes.

Choose Grips Tab
9
The Zeus has 12 grip patterns. The clinician can choose the grips that are the most
useful in the patient’s daily life.
Pairing mode
In the paring mode, the grips are arranged in a hierarchical manner, allowing for
quick access. The rst level of division is based on the position of the thumb. When
the thumb is in the opposed position, the opposed group of grips is active and when
the thumb is in the non-opposed position, the non-opposed group of grips is active.
To switch between the opposed group of grips and the non-opposed group of
grips, the user has to move the thumb in the desired position and then provide
a Change Signal.
Within each group of grip, there are two subgroups - the primary group and the
secondary group. Each subgroup has two grips within it, the default grip and the
alternate grip.
To switch between the default grip and the alternate grip, provide a Change
Signal.
To switch between the subgroups, primary group and the secondary group,
provide a Secondary Change Signal.
When you change the position of the thumb, provide a Change Signal to allow
the prosthesis to change between the opposed and non-opposed group of grips.
REMEMBER This works only with Control Modes - Pairing Mode

Choose Grips Tab

Sequential mode
In the sequential mode you can cycle between the grips in the loop. Using the
Change Signal (CS) you go forward in the loop; using the Secondary Change Signal
(SCS), you go back. The grips are split into two groups: with the thumb opposed
and non-opposed. To switch between the groups, you need to manually adjust the
thumb position and a Change Signal or a Secondary Change Signal.
The order and number of grips of each of the groups can be modied after selecting
“sequential mode” in the Settings Area.
In sequential mode there can be a maximum of 5 grips in each of the groups dened
by the thumb position. This number can be decreased by unchecking the last grip
in the group - the unused grip will be grayed out. You can re-activate the grip by
checking the box over it.

EMG Settings Tab
10
In the EMG Setting tab you can visualize the graph depicting the signals and their
strength acquired from the patient’s muscles.
To accommodate for varying levels of signal strength and electrode sensitivity,
there are special slider adjustments to change the threshold levels for the grip
change signal and the activation levels to open and close the hand.
On the left side of the screen there are 2 sliders with a scale. They can be easily
adjusted to establish a suitable grip change signal threshold for each patient
individually.
On the right side of the screen there are 2 additional sliders. They can be used
to adjust a suitable activation level for the open and close signal.
You can adjust the timescale on the graph by slider at the bottom of Settings
Area.
You can hide or show the thresholds on the graph by toggling the checkbox
beneath their sliders.
You can adjust the gain of the electrodes to change the strength of the signals
by moving the sliders on the bottom of the screen. It is recommended to change
the gains on the electrodes rst, and adjust the software gains for ne-tuning.
There are a couple of options that aect the appearance of the graphs.
Combined - in this option, both muscle signals (Flexion and Extension)
are shown on the same graph

shown on the separate graphs.

EMG Settings Tab
Proportional - this option enables you to change the thresholds for
proportional control of the hand. Both of the signals are visible on the
same screen. The thresholds are available on the right-hand side of the
Settings Area. Ther is also a special “Full power” threshold which is used
for Soft-grip functionality.
The threshold bar reects how high each signal must reach to register as a valid
signal. It veries if the signal the patient made is strong enough to be read and
for the hand to start moving.
If the patient has problems controlling the hand, the threshold bar can be
adjusted.
Adjustment Eect Consequence
Raising
Patient needs a higher signal
in order for the hand to start
moving
Patient must work harder
+ hand may seem slow to
respond
Lowering Patient needs weaker signal
for the hand to start moving
More potential for
inadvertent operation /
accidental opening
