Radar is an acronym for RAdio Detection And Ranging and is often perceived as large high-power systems detecting airplanes and ships. XeThru technology performs far beyond traditional radar systems when it comes to compact size, power consumption, accuracy, speed and low emissions. In fact, XeThru emits less energy than is allowed as unintentional radiation from your TV or vacuum cleaner (FCC part15).
A vast number of sensors and sensor technologies exist today, the most common being infrared (IR), capacitive, ultrasonic, and microwaves. Due to the strengths and weaknesses of different technologies, sensors are typically designed for only one task, such as detecting presence, motion, speed or distance. This is typically at one defined range or at very short range, or only on moving or static objects, and so forth. In applications where you want to combine features from several sensor technologies and/or hide your sensor due to security or other design constraints, your options are limited. This is why we set out to develop our XeThru technology and gave it the abilities it has today. XeThru is based on a single chip implementation of an Impulse Radar system and features the following abilities:
XeThru is able to measure its distance from a person, which provides a completely new set of possibilities. Imagine a simple application like sensor behind a painting in an art exhibition or even in the wall seeing through everything and detecting a person as he approaches. When he enters the viewing zone, he is welcomed and told information about the painting. If he gets too close, the system warns him to keep his distance, and sets off an alarm if he does not listen. When viewers leave the viewing zone, they are wished a pleasant stay at the gallery. Analogous ideas could be applied in settings from home automation to interactive commercial screens.
Detecting presence is an important function for XeThru. In home and building automation, presence detection is crucial even if a person is sitting still. One of the greatest strengths of XeThru is that it is able to detect presence from a person’s breathing, even if he is sleeping on the couch or sitting still in his office reading. This increases comfort level because the person does not need to keep moving all the time to keep a light on. This is also a big advantage in security applications. The detection range of this function is easily programmable, avoiding detection outside your desired range.
XeThru technology got its name from its most unique feature: the ability to see through objects. Our sensor can be used in the growing home automation market where it can see through walls, ceilings and doors, enabling everyday products to come to life. This function can also be used in commercial settings to see-through normal building materials, product casings, and even in the art world to look through a painting in a gallery. The XeThru sensor can be built into walls or products thereby enabling hidden and tamperproof installations without compromising design or security. This unleashes designers to think in new ways to develop the most advanced sensors ever
Detecting motion is something XeThru can do very well. Its sensitivity enables it to detect very small movements like the ones from your chest when you breathe, or larger movements such as walking.
XeThru technology has many fantastic capabilities. One of the most amazing features of XeThru is its flexibility: XeThru can combine all its features through adaptive sensing. Our technology can seamlessly switch between features and adjust parameters such as detection range and sensitivity during operation. XeThru truly combines flexibility with robustness.
