IPAS Flash Light Zone Tag
● Overview
IPAS Flashlight Tag is a safety-assisting device which prevents collisions between vehicles by signaling
dangers in 2 way communication to people in industrial working site.
Signal processing tag determines the distance from Zone tag to Vehicle Tag based on the time delay of
the return signal. The tag are configured to a caution and a danger areas.
When a vehicle enters into the caution and danger area of the zone tag, the light flashes from the tag.
The two areas are factory pre-set to default distances; they can be reconfigured for different distances
using setting buttons. The sensitivity was pre-calibrated at the factory, assuming that the detecting field
will be clear of obstacles. The sensitivity cannot be adjusted by user’s handling.

Hysteresis, applies to IPAS, is a dynamic lag between an input and
an output that disappears if the input is varied more slowly; this is
known as rate-dependent hysteresis. However, phenomena such as
the magnetic hysteresis loops are mainly rate-independent, which
makes a durable memory possible.
Systems with hysteresis are nonlinear, and can be mathematically
challenging to model. Some models such as the Preisach model
(originally applied to ferromagnetism) and the Bouc-Wen model
attempt to capture general features of hysteresis; and there are
also phenomenological models for particular phenomena such as
the Jiles-Atherton model for ferromagnetism.
