Twisted Pair – The wire used to interconnect Sensors, Collectors, and interfaces is
twisted into pairs to make the wire characteristics more uniform and to cancel out many
types of interference to which the wires might be subjected (see UTP).
USOC – Acronym for Universal Service Ordering Codes. The connectors and wiring
adhere to the USOC wiring practices standard wherever possible.
UTP – Acronym for Unshielded Twisted Pair. This is the typical solid, paired wire used in
phone system installations. It has no outer shield layer (see Twisted Pair).
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.
A. 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.
B. 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.
