GS2 Wheel
The GS2 Wheel is a completely self-contained unit consisting of a circuit board, battery, receiver, electric motor, and braking band. The GS2 Wheel comes fully assembled with its own caster.
Operation
The GS2 Wheel contains a digital circuitry board, which receives coded RF signals from in-store transmitters. The GS2 Wheel translates the coded signal and, depending on the specific signal received, triggers a motor inside the wheel to either engage or disengage the internal braking band. The wheel also translates a series of timed permission signals which allow or prohibit the wheel from exiting the store.
Form Factor
Standard-size wheel with replaceable non-marring anti-static rubber tread, sealed precision ball bearings, and standard caster
Dimensions
5" diameter x 1 1/4" width
Power Source
One replaceable CR123A, 3-volt lithium battery
Microprocessor
Digital programmable CMOS (low power consumption) micro-processor
Electronics Housing (Hubs)
High-tensile strength reinforced plastic with glass strands for extra strength and durability; dual O-rings provide watertight seal
Battery Life
Approximately 4,000 cycles (one lock & one unlock)
Exit Manager
Typically installed at each exit, the ExitManager contains a microprocessor that generates and transmits two distinct digitally-encoded signals that travel through wires embedded in the floor surface. The multi-functional ExitManager is capable of transmitting both a locking signal and an in-store timed permission signal. The wall-mountable enclosure also contains a power supply transformer and a filter to reduce electromagnetic interference.
Dimensions
7" high x 5 1/2" wide x 2 1/2" deep
Microprocessor
Digital circuitry, factory-programmed and compliant with international regulations
Signal Output
Below 9 KHZ and complies with FCC Part 15
Battery Backup
12V non-memory Ni-Cd battery backup array supplies 10 hours of uninterrupted backup
Purchase Manager
Mounted inside of each checkout, the PurchaseManager sends a wireless digital-coded signal to the GS2 Wheel as it passes through an active checkout. The "exit permission signal" allows the paying customer to freely exit the store after making their purchase. The compact enclosure also contains a power supply transformer and a filter to reduce electromagnetic interference.
Dimensions
8 1/2" high x 4 1/2" wide x 2 1/2" deep
Microprocessor
Digital circuitry, factory-programmed and compliant with international regulations
Signal Output
Below 9 KHZ and complies with FCC Part 15
Battery Backup
12V non-memory Ni-Cd battery backup array supplies 10 hours of uninterrupted backup
CartKey
Handheld wireless device used to either unlock or lock GS2 Wheels. The CartKey sends a digital signal to the GS2 Wheel that automatically unlocks or locks the wheel.
Form Factor
Water-tight, high-strength plastic with shock-resistant rubber boot; touch pad features two individual sealed dome switches labeled "Lock" and "Unlock"
Dimensions
6 1/4" high x 3 1/2" wide x 1 1/4" deep
Power Source
Field-serviceable CR123A, 3-volt, lithium battery identical to the one installed in the GS2 Wheel
Signal Output
Below 9KHZ (VLF) and complies with FCC Part 15
Signal Range
4' maximum range; optimal signal range: 18" - 48"; wireless signal range enables point-and-click unlocking
Signal Antenna
For a standard purchek™ application, the cable is 22-gauge (AWG) insulated wire embedded in the existing floor surface, either in a scored groove in concrete, or in existing grout lines between ceramic tile floors
Signal Range
The digital signal carried by the antennas has an effective range of 3 feet on either side of the embedded wire. The signal is adjustable (via the ExitManager) and can be tuned to accommodate a variety of installation scenarios.
Dimensions
Outside diameter: 1/8" |
