A stability
expert in a chip:
LifeTrack technology lets you embed your stability expert's detailed
product knowledge and stability calculating experience into an inexpensive
electronic chip.
Programmed with your product's precise time-temperature sensitivity curve,
it can stay with your product throughout its lifetime, constantly monitoring the impact of temperature and time,
and constantly computing the product's remaining storage-life (shelf-life). It's
intuitive display shows remaining shelf-life at a glance.
LifeTrack technology computes the integral of time and a user programmed
temperature function, and tests if the cumulative value is acceptable.
Example of a LifeTrack visual display showing
an unexpired product (+) with about 75% remaining lifetime.

Intelligent monitoring:
LifeTrack technology allows
sensor tags to be
flash-programmed with the precise details of your product's stability. This allows
sensors to know exactly what conditions your product tolerates, and how long it can last, at
every temperature from -20 oC to 70 oC.
Accommodates complex stability profiles.
Examples: The
graphs below show how LifeTrack technology can accurately monitor the
stability of five different materials: Milk, Seafood, Blood, Insulin, and MRE (highly stable canned food).

at lower temperatures, the lifetime of insulin and MRE is many years, and
thus extends off the chart.

freezing temperatures, and thus have a high P(temp) below 0 oC.
RFID standard compatibility through memory
efficient logging
and temperature statistics:
Want to create an EPC Gen 1
or Gen 2 standard RFID tag with an embedded time-temperature data logger?
Normal data loggers send out massive amounts of extraneous data, quickly
overwhelming the limited amount of RFID memory available in the standard EPC
format. LifeTrack technology conserves precious tag memory by allowing
you to send just the most important part of the log: exactly when and how an
unacceptable temperature excursion has occurred. Now you can have both
data logging and compatibility with existing EPC standards.
IR download from a LifeTrack technology
demonstration unit
This temperature log, showing cause of
stability failure, was transmitted using only 150 bytes of data
The LifeTrack technology demonstration unit stores and outputs a
detailed temperature history log and statistics through its standard onboard
infrared port. Designed for easy internet connectivity, it's open-source data format
and standard "Perl/CGI" interface shows how authorized users can
have complete control
and ownership of their data. Each demonstration unit has unique security codes and
individual serial numbers, designed for compatibility with
FDA 21 CFR part
11 requirements. Each demonstration unit also has a 60x speed "QC test mode",
showing how LifeTrack technology devices can be rapidly validated.
