Demo Unit – Quick Start Guide

The Demo Unit is a demonstration unit that can be used to illustrate the functionality of Adam’s Hand® without the need of a socket, and is compatible with all major analog EMG terminal devices and electrodes available on the market.

Package content

The Demo Unit package includes a quality control document, the device’s Quick Start Guide, a card with the QR code to download our MyoLogic Pro App, where you can also find the digital version of the device’s Manual and all the relevant documentation, a Warranty Card, the Demo Unit and its base.

A printed version of the manual can be found in the package, too.

If the Demo Unit is purchased together with the Adam’s Hand® for demo use, the hand and all related documents are included in the package.

The Demo Unit can also be purchased in the “Demo Pack” bundle which, in addition to the Demo Unit, includes the Adam’s Hand®, a ThunderCell Battery® and its charger.

Demo Unit main features

The quick release lamination kit integrated into the Demo Unit has a 6-band coaxial connector, two dedicated to analog signals, two to digital communication, and two to power.

On the front side the Demo Unit has a two-degree-of-freedom proportional joystick that can be used to open or close the hand – or to rotate it clockwise or counterclockwise if a wrist rotator, not included in the package, is added.

The device also features two connectors for analog EMG electrodes and two connectors for digital EMG electrodes which can be used to operate it.

The Demo Unit also includes our battery receptacle, so it can be used with our ThunderCell Battery®.

Connecting the hand, turning the device on/off and controlling the Demo Unit with joystick

To use the Demo Unit, first connect the Adam’s Hand using the quick-disconnect joint and insert the ThunderCell battery® into the receptacle. 

At this point, you can power on the Demo Unit with a long click on the battery button. Switching on is signaled by the green double flashing of the LEDs on the battery and hand buttons, and by the lighting up of the two white LEDs on the Demo Unit.

Using the joystick, you can control the hand’s opening/closing by moving it up or down, and if a wrist rotator is added to the Demo Unit (not included in the package), you can also control the clockwise or counterclockwise rotation of the hand by moving the joystick sideways.

To turn off the device, a long click on the battery button. The power-off is indicated by the red light of the battery LED.

To recharge the ThunderCell Battery®, you have to remove it from the Demo Unit receptacle and connect it to the USB-C charger provided together with the Demo Unit.

Controlling the Demo Unit with the EMG electrodes

The Demo Unit features 2 connectors for analog EMG electrodes to calibrate and easily control the Adam’s Hand®. To do so, you have to connect the electrodes to the Demo Unit.

To switch from “Joystick Control Mode” to “Electrode Control Mode”, double-click on the joystick. Once done, the Demo Unit will give a short acoustic feedback and the white LED corresponding to the analog EMG electrode connectors will light up.

At this point, you can control the hand’s opening and closing using the EMG signals.

To return to “Joystick Control Mode”, double click on the joystick. The white LED at the analog EMG electrode connectors will turn off.

Calibration and use of the Adam’s Hand® with Demo Unit and EMG Electrodes

You can also connect the Demo Hand to MyoLogic Pro, an optional app released by BionIT Labs.

To add the Demo Hand to your device’s database on the app, scan the QR code you find inside the Package.

To do so, click on “add device” in your device’s database on the Myo Logic Pro app.

Then, check the device section on the app and connect to the available Demo Hand.

From the info screen, you can update the device’s firmware by clicking on the firmware update button.

To calibrate the Demo Hand with the EMG electrodes make sure to switch to “Electrode Control Mode”. 

Now you can both check the EMG signals and you can perform the calibration procedure.

So, start by resting, then contract the wrist flexors (close the hand), and finally contract the wrist extensors (open the hand).

At this point you can save the calibration and you can immediately check the device functioning.

You can also see a virtual model of the hand so that the patient can train without even having the socket ready.

If a wrist rotator is mounted on the Demo Unit, after the standard 3-phase calibration, the app will ask you if you want to calibrate the wrist rotator, too.

To do so, you have to perform wrist flexors and extensors muscles co-contraction. This can be generally obtained by simulating a complete opening or closing of the fingers.

Once done, you can turn off the wrist rotator or select three different control modes to switch from hand to wrist control:

  • double opening or closing spike
  • co-contraction 
  • 4-channel control, through which the high intensity muscle contractions control the wrist rotation, and the low intensity muscle contractions control the opening/closing of the hand.

Demo Unit use and compatibility

The Demo Unit is also compatible with other analog terminal devices.

To switch to analog control, long click the joystick button: the two white LEDs on the Demo Unit will flash twice and the device will give a double acoustic feedback.

Now you can control the analog terminal device with the joystick.

To control the analog terminal device with the EMG electrodes, just switch again to “Electrode Control Mode” with a double click on the joystick.

To switch back to digital control of the Adam’s Hand®, simply turn off and on the Demo Unit, by long clicking on the battery button, or long clicking the joystick button again. In this case the two white LEDs of the Demo Unit will turn on for a long time and the device will emit a long acoustic feedback.
