IR.Loc technology

Inexpensive and discreet infrared localization

 Locating People

Ambiplex uses off the shelf standard components similar to those to be found in today's motion detectors. Contrary to conventional motion detectors our sensor solutions detect non-moving heat sources, such as sleeping persons. Moreover, they provide a large amount of additional information about the heat source (e.g. source size).

Ambiplex' base technology, IR.Loc, stands for a group of methods and algorithms for detecting and locating heat sources, particularly human beings. For this purpose, infrared radiation which every heat source emits by nature is detected using inexpensive infrared sensors. The sensors' output is then electronically processed. The technology offers robust, customer specific, passive presence detection and localization solutions for indoor usage. It is versatilely applicable, e.g.:

  • in home automation and security
  • in health care
  • for man-machine interaction
The uniqueness of Ambiplex' solutions for these application is our signal processing. The 'cleverness' of our algorithms enables the simple sensors to act as a versatile and inexpensive localization system. For the development of our technology we have developed our own tools, such as IRSimulator 3D.

 Electronic angle measurement for localization

Our devices determine the angle of incident heat radiation. Contrary to existing approaches this measurement is performed entirely in electronics, i.e. no mechanical components need to be used. When several sensors are combined to a system of sensors, it is possible to compute the location coordinates of located heat sources, given that the geometric arrangement of the sensors is known.

The pure electronic angle measurement is one of the central innovations of the IR.Loc technology. Thanks to the ground breaking signal processing, we achieve an extremely high angular resolution. Only with high performance algorithms as these, it is possible to implement localization employing such simple and inexpensive sensors.
