ANGEL – Smart Electrical Safety Assistant

  • Providing immediate help in emergencies

    In the event of falls, loss of consciousness, and electric shocks, the ANGEL system can reliably detect medical emergencies and make an emergency call to enable that help arrives quickly. The last known GPS location and accident data are passed onto emergency personnel. They could be in-house first-aiders or an external emergency call center.

  • Saving lives by switching off electrical sources

    In the event of an electric shock, every millisecond counts to avoid permanent or life-threatening injuries. The ANGEL Watchdog (expected to be available from 2022) can be installed to increase safety in a wide variety of situations, in which it disconnects the electric circuit within milliseconds in the event of an electric shock. The quicker the current flow is disconnected, the less severe the injuries and the lower the risk of ventricular fibrillation or blood poisoning.

  • The perfect companion for carrying out dangerous work alone

    Even when working alone is permitted, it’s probably a good idea for someone else to be there. The ANGEL system identifies emergencies and calls for help. In the event of an incident, ANGEL provides help and therefore increases the safety of those who work alone.

  • Increasing occupational safety awareness through statistics

    Every emergency is detected. You receive regular reports and evaluations from your team, enabling you to analyze and rectify the causes of small accidents to avoid serious ones. This process ensures that your employees become more aware of their safety in their everyday working environment – reducing possible downtimes. You learn what is “normal” in your sector and what is not. You can learn from others, and others can learn from you.

ANGEL – when smart electronics and comfortable textiles merge. ANGEL is the intelligent workwear for emergencies in the electrical sector. The electronics recognize an electrical accident or a fall via integrated electrodes and can automatically activate the individual rescue chain. In addition, the manual alarm can be started for further emergency situations. When working with an increased risk, the task timer can be activated to ensure rapid assistance.

Intelligence through
perfect synergy

The fab four offer many advantages
The four components include a clever Genius together with a smart textile shirt, an intuitive app on your cell phone, and a quick-response ANGEL Watchdog that disconnects sources of electrical power.

Central control unit – the Genius

The Genius is the brains of the system. It clicks into the cradle (the holder) on the shirt and communicates with the user using optical and acoustic signals. The Genius detects the voltage drop on the body, monitors the movements of the user, and notifies the emergency call center using the smartphone app which is connected via Bluetooth® technology. (see below left).

  • Powerful processor for detecting emergencies
  • Battery life of 2 days
  • Light and compact
  • Blends in perfectly with the shirt
  • Powerful magnets provide a secure grip on the upper arm
A suitable holder – the cradle

The cradle is a sleek holder for the Genius. Its curved shape allows it to fit perfectly around the upper arm. You can barely even notice the electronics protecting you.

Conductive materials and electrodes

The conductive textile cable connects the sensors on the upper arms to the Genius. The voltage between the upper arms is measured using electrodes, from which the current level is deduced. The silicone electrodes detect a voltage drop. Elastane in the cuffs provides close skin contact. A perfect fit is essential because only then the ANGEL system can provide reliable protection.

Individual branding

Uniform appearance is guaranteed: the shirt is available with your company-specific branding.

Extremely comfortable

The smart textile shirt is made of eco-cotton, kind to the skin, durable, easy to clean, and comfortable to wear thanks to its generous cut. Attractive stitching gives the shirt a sporty look.

Smartphone App

Your smartphone is connected to the Genius via Bluetooth® technology and displays live data. If necessary, it can make an emergency call.

How does the emergency call chain work?

Users are often unable to respond appropriately or unaided in an emergency situation. Thanks to its sophisticated and automatic emergency chain, ANGEL ensures help is on hand quickly.

The user stores her/his personal data and the data of her/his emergency contacts in the ANGEL portal during registration. In the event of an emergency, such as automatic accident detection, a manual alarm, or an expired task timer, the personal rescue chain is activated. The emergency contacts are informed via SMS and an automatic voice call and can thus ensure rapid assistance. The location of the person involved in the accident is sent via SMS.

Facts regarding electrical accidents

What happens when current flows through the body? Why are electrical accidents so dangerous if they are not treated medically?

Several thousand companies incorporate the Austrian electrical industry – this corresponds to approximately 50,000 employees and an annual turnover of EUR 18 billion.

Source: Austrian Chamber of Commerce, Electricial and Electronical Industry Report 2018

In 2018, 254 electrical accidents happened, of which two were fatal. The most common causes of accidents were defects in the electrical system and carelessness. About a third of the casualties were electrically qualified persons.

In addition to the monetary consequences of being unable to work, work processes have to be reorganized, accident analyzes need to be drawn up, retraining courses carried out, and colleagues looked after.

68% of all workers would use smart wearables for their daily work if they can take advantage of their work safety and if personal data is protected. These solutions are, therefore, an essential component for industry 4.0.

Questions & Answers

Please get in touch with us if your question is not answered below.

  • At which voltage threshold does the ANGEL system respond?

    In a nutshell: There isn’t any, and that’s a good thing. It is not the voltage itself that is harmful but the current that flows through the body. The Genius measures the voltage drop between the upper arms, which indicates the current flowing through one of the two arms. It is, therefore, irrelevant whether the voltage is high or low. The trigger threshold of the Genius is typically at a single-digit milliampere level.

  • Can the shirt detect every type of electrical accident?

    ANGEL recognizes when there is a current flow through the body and a voltage drop between the upper arms. As the circumstances behind an electric incident are many and vary, we cannot guarantee that every single one will be detected.

  • Is ANGEL suitable when working on live systems?

    Working on live systems is subject to a particular set of rules that may not be altered or reduced, even when using a smart textile shirt. You should always try to work following the five safety rules. The system provides an additional level of safety if a fault occurs.

  • What happens if I jump off the ladder?

    The fall detection is a combination of free fall with subsequent immobility. If a significant shock occurs, the fall sensor starts recording the fall, integrated into the Genius. The fall sensor detects false alarms by analyzing falls and recognizing whether it is necessary to trigger an alarm or not. In fact, the automatic alarm triggering is only activated if the person remains motionless after the fall, as we then assume a real emergency. Therefore, fall detection is not activated in every fall situation, e.g., when jumping off the ladder and then walking away.

  • How come I can’t just use the motion sensor in my cell phone?

    To reliably detect movement, the cell phone would have to be carried on your person at all times. As most users don’t do this, ADRESYS has developed an intelligent Genius system that can be fastened to the smart textile shirt.

  • Can emergencies still be detected without cell reception?

    Cell phones use either the cellular network or a direct data connection such as Wi-Fi. If neither link is available for more than 15 minutes, the cell phone will prompt you to reestablish the link. You can also set a work timer – you can activate this timer before you carry out dangerous work or before you, for example, work in a basement with no reception. If the timer has expired and you do not end the alarm, the rescue chain is automatically informed.

  • Will the shirt protect me in the event of an arcing fault?

    To provide protection in the event of arcing faults, the usual recommendation is to wear flame-retardant clothing over a cotton shirt, as man-made fabrics can melt onto the skin. We recommend that you wear your ANGEL shirt next to the skin. The wearing of flame-retardant clothing appropriate to the risk situation over the shirt is a mandatory requirement.

  • Does ANGEL qualify as personal protection equipment in the sense of EU Regulation 2016/425?

    No, ANGEL is a voluntary additional equipment and therefore not a personal protective equipment within the meaning of the EU Regulation (EU) 2016/425 of March 9, 2016 and does not replace any otherwise compulsory protective clothing or protective equipment.

  • Can ANGEL rust?

    No. Sweating and washing cause moisture in the textile, but we have developed our technology to be waterproof. If the specified care instructions are followed, there will be no functional loss after up to 50 washing cycles. We also use rust-free material, such as stainless steel, for our barbed rivets in the connection plate.

  • Will the ANGEL bluetooth connection be disrupted if I am using another Bluetooth device at the same time?

    No, Bluetooth® uses several different frequencies, so that interference is very unlikely. Only too many Bluetooth® devices in a confined space can lead to reduced performance and short interruptions, which are communicated acoustically.
