Frequently Asked Questions
Questions about the usage
How does the social distancing functionality work?
When one user is too close to another, a warning signal is given. Your bracelet alerts you by vibrating and through a red light. The alarm stops as soon as both people move back to a safe distance from each other. No personal data is shared or stored in the cloud.
Rombit devices intentionally warn through vibration and light only. Our research and user testing have shown that for these purposes audible alarms are counter-effective in the long run because they tend to distract and annoy users.
How does the contact tracing functionality work?
The contact tracing add-on can be purchased and activated at any time.
When active, a designated and authorized person can consult the encounter registry. They can identify the bracelet ID of an employee that is presumed to be infected after written consent. A list of bracelets that have been too close to this user can be generated. The physician can then inform users that have been in close contact with the infected employee.
The storage of all personal information is fully encrypted and compliant with GDPR guidelines. All contact tracing data are stored for 14 days, the typical incubation period of the COVID-19 virus.
How do I wear the Rombit wearable ONE™?
Rombit wearable ONE™ can be worn on either your wrist, arm, ankle or helmet.
How can I activate additional functionalities such as Personal SOS Alert, Collision Warning... ?
The Rombit wearable ONE™ device can be upgraded with any of the available Romware functions, such as ‘Personal SOS Alert’, ‘Man-Down Alert’, ‘Collision Warning’ and more.
Consult your Rombit representative to discover what hardware is the best choice for your current and future requirements.
How loud is the alarm of the Rombit wearable ONE™?
The Rombit wearable ONE™ does not rely on sound to notify the user.
This is intentional. User testing shows that noisy alarms tend to be either too quiet or too loud for their environment, distracting the user or going unnoticed.
As both add to the risk of ignoring alarms altogether, we designed Romware around haptic feedback and easy-to-understand light cues.
What safety level / performance level does Rombit provide? Can Rombit be used as a safety component / safety interlock / emergency stop?
Our current offering is intended and marketed as Assistive technology. It is a system intended to help warn users of potentially unsafe situations and to raise awareness of the risks involved. As such, it is NOT intended to be used as a safety component of a machine setup as meant in article 2(c) of the European Machine Directive 2006/42/EC.
The current Rombit suite is not considered a ‘machine’ as defined by the European Machinery Directive (2006/42/EC):
- It does not contain moving parts, nor a driving unit.
- It is not considered a safety component as defined in Article 2(c) of the directive.
- As Safety Integrity Level (SIL) EN IEC 62061, and Performance Level (PL) EN ISO 13849-1 are norms used to implement this directive, they are not relevant to the current Rombit suite.
In a number of cases, Rombit products can directly control a vehicle on a hardware level. An example is the Credential-based vehicle access solution. These products are designed to prevent unauthorized starting of the vehicle, not to intervene with the vehicle controls. A sudden change in movement, unanticipated by the driver, could create a more dangerous situation than it was meant to prevent. Therefore, Rombit products only intervene by giving the user auditory, visual and haptic alerts, not by controlling the vehicle in any way while it is in use.
The Rombit suite is designed to be integrated. When directly connecting Rombit products to existing machinery, it is the responsibility of the system integrator to assess the suitability of the Romware products for a particular setup.
Rombit is not intended in any way to function as a safety-stop or safety-interlock function of the vehicle. Any integrations that use the system as such are not supported by Rombit.
Is the Romware wearable sensitive enough to discern a mimimum distance violation for social distancing?
All Rombit physical distancing products measure distances using UWB (Ultra Wideband) technology. Independent studies acknowledge that UWB is the only available technology that is accurate enough for a reliable social distancing solution.
What's the typical battery life of the Rombit wearable ONE™?
Rombit wearable ONE™ has autonomy between charges between 10 and 18h. As with all mobile devices, autonomy depends on cell coverage, conditions such as temperature, and the number of activated features.
A charging cable is included that can be used with standard USB charging adapters, such as a mobile phone charger.
How do I charge the Rombit wearable ONE™?
Rombit devices can be charged using the included cable. The charging cable can be used with standard USB charging adapters, such as a mobile phone charger.
How does the Rombit wearable ONE™ alert the user when the battery is low?
A blinking LED and vibration alert the user when the device needs to be recharged soon.
How can I charge many devices at once?
Rombit wearable ONE™ is delivered with a USB-compatible magnetic charging cable.
For charging multiple devices at once, it is possible to use available multi-port USB chargers.
A dedicated mass charging and storage solution for deploying large sets of wearables is scheduled for a Q4/2020 release.
What's the expected lifetime of Rombit wearables? How long will the battery of Rombit wearables last before wearing out?
Both Rombit wearable ONE™ contains a rechargeable Lithium-polymer battery. This battery is optimized for continuous use in an industrial environment.
In normal use, a useful lifespan of 4 years is to be expected until the battery capacity is significantly reduced. To keep Li-ion batteries in optimal condition, charge your device whenever convenient. Avoid completely discharging too often or keeping the device in extreme heat or cold (such as a parked vehicle) for prolonged periods, especially while charging.
Rombit Wearable One™
Health, hygiene, and safety
What is the risk of getting stuck in machinery or equipment?
The Rombit wearable ONE™ is designed to the highest safety standards. This allows their use in environments that typically do not permit bracelets or jewelry worn on fingers, wrist, or neck.
The wrist strap of Rombit wearable ONE™ is designed and tested to disengage at 50N of pulling force, to minimize the risk of getting caught in for example rotating equipment.
Based on our extensive research, the compact wrist-worn design of Rombit wearable ONE™ offers the best balance between accuracy, worker safety, and user comfort.
Does wearing the device impede or hinder the user from accomplishing normal work activities during a typical work shift?
When a person is expected to pay attention to messages in addition to the task at hand, the risk of being dangerously distracted increases significantly. This phenomenon, called inattentional blindness, is known to be increased by pop-up messages like those on cell phones and smartwatches.
This is the reason that from a safety standpoint, the use of these devices is heavily discouraged or even forbidden during high-consequence activities.
The Rombit wearable ONE™ helps in minimizing this risk of distraction, using alarms that are designed to be concise and not dependent on reading screen messages.
Can the device be used while using medical devices such as pacemakers?
All Rombit devices are tested to be compliant with FCC, ETSI and the CE Radio directive to minimize the risk of interference with other equipment. As a precautionary measure with all radio devices, consult with a physician before using Rombit for persons using medical devices such as a pacemaker.
Can Rombit wearables be easily cleaned or disinfected against COVID-19?
COVID-19 related viruses are known to withstand more than 48 hours on surfaces under certain conditions. As a precautionary measure, Rombit recommends following this guidance for cleaning and disinfecting both the casing and strap, especially when passing on the product to another person.
– Wipe the device and strap thoroughly with a 70% v/v solution of isopropanol or ethanol, with a clean soft cloth. Using disposable individually wrapped isopropyl alcohol wipes is a good method for preventing cross-contamination.
– The efficacy of disinfectants is reduced on dirty surfaces. When the device or strap is visibly dirty, clean it first with a mild soap solution and rinse with water before disinfecting.
This guidance is based on the latest recommendations of the European Center for Disease Prevention and Control at the time of writing (Interim guidance for environmental cleaning in non-healthcare facilities exposed to SARS-CoV-2, technical report 2/2020). As the effectiveness of certain cleaning products and disinfectants against COVID-19 is not yet fully known by health authorities, Rombit recommends checking the latest guidelines, which can be found on http://www.ecdc.europa.eu.
Are there allergy concerns regarding the use of the Romware wearable ONE™?
The Rombit safety wearable is designed to the highest safety standards and manufactured from high-purity materials. The wrist strap is designed to eliminate skin contact with known allergens such as nickel, is latex and BPA-free, and is food-contact safe.
As with all things worn close to the body, it is not good for your skin to wear a wet or dirty wristband for extended periods, as moisture and bacteria can cause irritation. We recommend cleaning the band and wrist regularly, especially after intense sweating or working in very dirty environments. Do not use aggressive products to clean the wristband, as residue could get trapped underneath and irritate the skin.
Be aware that products such as lotions, perfume, soap, or insect repellants are known to get trapped under items, such as jewelry and wristbands and cause irritation. Therefore, it is always a good idea to take off the safety wearable when not working, to allow your skin to breathe.
Is the strap material of the Rombit wearable ONE™ certified for hazardous materials?
The strap of Rombit wearable ONE™ is manufactured from a high-grade silicone elastomer. It was independently tested to be compliant with legislation, being free of hazardous substances such as heavy metals, halogens, PBBs, and PBDEs.
