The Sonitor ultrasound indoor positioning system (IPS) automatically tracks precisely by room the real-time location of moveable equipment and people in complex indoor environments. The Sonitor system uses wireless detectors and "Tags" that are linked to a digital file containing all vital statistics and information about the item or person being monitored. The motion activated Tag transmits a unique identification signal using ultrasound waves to detectors that use Sonitor patented Digital Signal Processing (DSP) algorithms, which transmit signals via an existing LAN to a central computer that stores the information about the Tag's room-location and the time of receipt of the signal.
Sonitor patented DSP algorithms ensure that the detectors interpret the Tag signals without risk of interference from any environmental noise or other signals nor interfere with sensitive instruments. This is particularly important in a hospital or other complex healthcare setting.
The Sonitor system uses ultrasound as its means of communications. Ultrasound has several desirable properties that make it ideal for this application.
- It does not penetrate solid walls, so location per room is simple to achieve.
- It does not require line of sight between the tag and the detector, making it possible to track objects that are hidden or located in drawers or filing cabinets.
- Ultrasound waves are mechanical waves, and therefore are immune to interference. They do not interfere with sensitive equipment that might otherwise be disturbed by electromagnetic waves.
- The security of an ultrasound system is very high, making it virtually impossible to eavesdrop on the communications link from outside the premises of the installation.
The Sonitor ultrasound system has been designed for safety, so all emitted sound pressure levels are within the international regulations for the safe use of ultrasound. The mystery of the bat's way of communication and navigation has fascinated mankind through all times. Our ears are not capable of picking up the most fascinating and pervasive night sounds, the ultrasonic echolocation calls of bats. Bats have been navigating the night skies for more than 50 million years, but it was not until the late 1700s that people began to understand and appreciate just how sophisticated the orientation system was. Late in the eighteenth century, an Italian scientist, first documented that bats were using a kind of "sixth sense" to navigate in complete darkness. Sonitor Technologies has now managed to make a practical Indoor Positioning System (IPS) inspired by the ultrasound used by bats.
The Sonitor® IPS Tags
The Sonitor® IPS Tags are battery powered wireless devices attached to movable objects or people. When moving and/or at predefined intervals, the Tag will transmit its own identification number via ultrasound waves. The nearest Sonitor® IPS Detector receives the signal, analyzes it and forwards the information to the database on the centralized Sonitor server.
E-Tag - The Sonitor® IPS E-Tag has two push-buttons which can be individually configured to send messages applicable to the object the Tag is attached to, e.g. Needs repair, Needs cleaning, Needs transport, Help. The Tag can be delivered with tampering sensor. Standard attachment methods are lanyard, tether, double sided tape, and bracket with screws.
