FAQ

Nominally, no maintenance is required outside of occasional cleaning of the LifeDisplay screen in dusty work environments. We often provide a tamper-proof, industry mount that protects all cable interfaces. 

The LifeBand includes a spare set of removable/replaceable sensor dots that can be changed by the user if excessively soiled or damaged.

Given that simplicity of our system (a wearable and a smart device), it can be used in many environments. The typical use case is driving or equipment operation, however Life by SmartCap can also be used in an office environment. To date, our product has been used in off-road trucks, road-going trucks, passenger vehicles, dozers and other construction equipment, ocean-going ships, trains, planes and control-room settings.

Yes. While simple to use, our training typically focuses on the interpretation of the fatigue levels, alerts and alarms, and guidance on proven responses to improve alertness when prompted. 

During initial training, we often receive a number of questions from users that range from the science inside the LifeBand to practical controls regarding data privacy. Our deployment team are well-versed in all aspects of our solution and its business application, so we strongly recommend being involved in the training/deployment.   

No calibration is required.

The LifeBand, much like other wearable devise, has an internal battery. The nominal battery life is 50 hours between recharges (which takes approximately 90 minutes via a simple magnetic USB charge cable). The cycle life of the battery equates to several years of every-day use.

The LifeDisplay is typically installed and hardwired to vehicle/equipment power.

Fatigue/alertness scores are updated every two minutes. This was a deliberate choice that has been well validated as an appropriate balance between sufficient opportunity to intervene prior to elevated risk (and well prior to microsleep) against excessive user feedback.

EEG is sampled at 256Hz, and second-by-second calculations are performed during confirmation. Confirmed scores are instantly communicated to the LifeDisplay.

Our proprietary algorithm performs calculations based on EEG measurements to produce a fatigue/alertness score. Specifically, the score is aligned with the Oxford Sleep Resistance Test (OSLER Test), which measures an individual’s ability to resist sleep. This is best described as an individual’s risk of unintentionally falling asleep.

 

The warning alerts and alarms are configurable, and are triggered based on a combination of fatigue/alertness score, and a duration (which may be set to instantaneous). Alerts/alarms are both audible and visual, and can be configured to require a user response (touch screen) to cancel the alarm sound.

 

Yes. There are three studies that are most relevant. Firstly, a controlled internal validation (laboratory) was conducted by the Monash University Accident Research Centre (MUARC) in combination with the Austin Hospital Institute of Breathing and Sleep (IBAS). This was a direct comparison between our fatigue scores and the OSLER test. A second external validation was conducted by the Department of Medicine within the University of Chile (Universidad de Chile), which assessed approximately 600,000 hours of operational data collected in a number of mining operations. The assessment scrutinised the data for chronobiological (circadian) trends on an individual and group level. In addition, the assessment incorporated a laboratory assessment of our raw EEG signals compared with clinical grade EEG.

Both of the above studies provided very strong support for our product’s accuracy (see next question/answer), the validity of long-term trends, and assessed our EEG as clinical-grade.

A third study was conducted by Rio Tinto, and established SmartCap customer, which assessed amongst other things the overall effectiveness of the SmartCap solution to facilitate reductions in fatigue incidents. Findings were presented at the Australian Institute of Occupational Hygienists (AIOH) annual conference in 2016, which showed dramatic reductions in both fatigue and human-error-related incidents.

 

The MUARC study provided the following results:

Sensitivity – 94.7%

Specificity – 81.0%

It is important to note that the OSLER test is designed to be a one-way test (able to identify impairment, but unable to confirm non-impairment). As such, we feel that the specificity is greater than 81%, however no validated measures exist to appropriately test this. 

 

For plant names to be shown on the Dashboard, they need to be the assigned to a combination of hardware that is (or has) communicated with Fatigue Manager.

If the plant names that you've added appear in the Plant list shown in CONFIG->PLANT, you've added them correctly. This is a list of names that can be given to a particular combination of hardware that is (or has) communicated with Fatigue Manager.

When the SmartCap hardware communicates with Fatigue Manager, it will show up on the dashboard as an "unassigned" plant. That is the point at which you can rename that hardware combination with one of the new names you've added.

 

SmartCap LifeHub is a tool for supervisors and managers to remotely monitor the SmartCap units deployed within the fleet. It provides an additional layer of fatigue alarming to ensure the most flexibility for each site to effectively monitor and manage fatigue in the workforce.

LifeHub is cloud hosted and can be accessed using any modern web browser. It offers a range of password-protected user types ensuring both operator privacy and access to configure settings suitable to each site.

LifeHub is the successor of Fatigue Manager, which was a locally hosted web application. 

What you CAN do with LifeHub

  • Monitor fatigue levels of the entire fleet in real-time
  • Configure fatigue alarms for equipment operators
  • Configure fatigue alarms for LifeHub users
  • Review the fatigue history of individual operators (restricted to limited users for privacy)
  • Identify when units are offline
  • Identify when operators are not using their LifeBand

 

What you CANNOT do with LifeHub

  • See brainwave information of SmartCap users. The SmartCap system provides fatigue information only
  • Send text messages to individual operators or SmartCap displays
 

Usage ranges between 500kB to 1MB per 2 hours session, which would put monthly estimates between 360MB and 720MB for 24/7 use. To be safe we recommend our customers use a 1GB data plan for LifeDisplays.

 

Yes. Our Life app can be installed on approved Android and Apple devices via the App Store.
