2. System Description
The Versus Information System is a reliable, flexible platform for locating people and equipment
indoors. The system badges, worn by people or attached to assets, emit infrared (IR) or a
combination of infrared and radio frequency (RF) signals that contain information about the
badge. The information is sent through the sensory network to a host computer that retrieves the
information and translates the data into names of rooms, people, and equipment. Workstations on
a LAN throughout the facility can access the location data with various client software programs,
which display the current locations of people and equipment. In addition, the system can display
alarms on the monitor, send pager messages, and store data for later use in reports.
System Structure
2.1 Infrared (IR) Tracking
The use of infrared (IR) signals for tracking has distinct advantages, since it allows accurate
locating via signals that will not penetrate walls or floors. A system of strategically placed IR
Sensors receives IR signals as badges move between rooms or areas of a building.
2.2 Radio Frequency (RF) Signals
In addition to the IR signal, a low-power radio frequency (RF) signal is incorporated into some
badges. RF signals penetrate walls and ceilings, allowing the RF signal to act as a backup if the IR
signal is blocked. If the IR signal is blocked and an RF Sensor receives the RF signal, the last
known IR location of the badge continues to display. In addition, the RF signal can be used in a
supervisory capacity to indicate a low-battery status or button press information, and can trigger
the Versus system to activate a pre-programmed response. RF badges and Sensors can also be
used for other purposes.
