KARDIAN can be used on a nightstand with Wi-Fi connection for homes and it can also be installed on the walls or ceiling of hospitals and nursing homes with simple wiring.
Unlike wearable based fall detection systems, KARDIAN can even detect slow "sliding falls".
Kardian devices are not affetected by dirt, dust, light or temperature. There is no physical maintenance to worry about. There is also no need to replace any parts unlike pressure pad based systems.
The core hardware technology powering KARDIAN is IR-UWB RADAR which stands for impulse radio ultra wide band radar. It sends out 20,000 nano-pulses per second and gather valueable data to its surrounding. Micro movements and vibrations such as chest movement from breathing and heart beats are detected and monitored. Fall detection looks at distance, movement and speed (time of flight) to determine falls.
IR-UWB stands for Impulse Radio Ultra Wide Band radar. It is essentially a very wide bandwidth (low emitted power) with lots of multipath. IR-UWB Radar operates at 6.5~8 Ghz, which does not interfere with any other known electronic devices (including medical equipment).
Kardians patented technology can detect and monitor health vitals such as heart rate, breathing rate, sleep apnea, fall detection and can also be used as a PERS (personal emergency response system) device.
IR-UWB emits very short energy pulses, typically on the order of hundreds of picoseconds, that are transmitted with the use of a specially designed wideband antenna. KARDIAN has developed unique algorithm that can use IR-UWB to create adjacent thin layers vertically creating a “field” that can detect health vitals.
IR-UWB operates at a wide, but low bandwidth – 500Mhz. In other words, it emits less than 10,000th to 100,000th less signals than a standard wireless Wi-Fi router. It is completely health-risk free to use on a daily basis.
4 out of 5 injuries that occur in bathrooms are caused by falls. 33% of seniors required hospital admission following a bathroom fall. In some instances, hospitals and nursing care facilities have been sued for negligence due to a bathroom fall while the patient was in their car. One of the biggest challenge has been privacy. Wearables are not waterproof and even if they were, customers wouldn’t want to wear them to the bathroom. Pressure pads on the toilet seat only tells the caretakers that the patient has come off the seat but not necessarily tell them if he/she has fallen or not. Cameras poses extreme privacy concerns, especially in a bathroom scenario. KARDIAN is truly the one and only solution available when it comes to providing accurate and reliable fall detection without any privacy concerns whatsoever.

Kardian has the unique ability to detect objects and people separately. With its radar technology, it can also auto-detect and calculate the distance of the floor. This is important as it can also determine if someone “fell” on a sofa or bed which could be intentional. Video below demonstrates various types of falls that can occur from a bed.

KARDIAN has a clear advantage over its competitors due to the fact that it uses a completely different technology that has never been available in the past. It has the highest accuracy rate, lowest false alarm alarm rate, is 100% contact free (wireless) and is most reliable to use over time since it is not affected by environmental contamination such as dust/grime build up, lighting and physical abuse (pressure pads).
All wearable based fall detection systems rely on accelerometer, gyroscope and sometimes barometer sensors to look for sudden falls. The key word here however is “sudden” as wearable devices are not able to look for slow, sliding falls or differentiate between intentional falls (to a sofa or bed) and accidental falls. Another major hurdle for wearable based fall detection systems is that it must be physically worn at all times. Many users prefer not to wear one while they are sleeping (accidental presses causes false alarms) or while they are in the bathroom.
The biggest concern for camera based systems is privacy. Even with facial recognition blocking technology, it still is a camera looking down on them in a bedroom. Furthermore, as it is "image processing", it requires much more computing power (more expensive) and it also requires physical maintenance along with ample lighting (not too much, not too little).
Since hospitals and senior care facilities cannot tolerate even a 1% chance of miss detection, pressure pad based systems are commonly used for fall detection. The system is carefully calibrated to detect for actual falls rather than when the patient is tossing and turning on the bed. This is also the reason why these pads comes with a limited 6 months or 12 months warranty period and has to be replaced. The entire setup is very costly and running expenses are usually in the hundreds of dollars per year.
