Sixth Sense Technology

6th Sense software makes an estimation of

the actual food temperature inside the

refrigerator and freezer compartment and

adjusts cooling to allow the food packages to

return their initial temperature faster during

pull down, door openings, or heavy food load.

6th Sense algorithm runs in both FC and RC

and each contains 3 routines: Trigger,

Package Estimator, and Defrost Manager.

• Trigger routine is executed every 2.5 seconds while Package Estimator and

Defrost Manager are executed every 10 seconds. The trigger routine is divided

into two subroutines: door monitoring and temperature monitoring.

Trigger parameters and performance parameters reside in the UI board, the

actual 6

sense algorithm resides in Gemini Flash board.

• Package Estimator routine computes an estimation of food in FC and RC

according to Thermistor reading and door status. Package estimator is run when

the User Interface sends the required parameters to Gemini flash and sets the

6th Sense Enable bit to true. If 6th Sense is needed, it will call for additional

cooling by turning on compressor, damper and evaporator fan.

• Defrost manager is composed of two main states: Normal and 6th Sense.

When 6th Sense routine is active, defrost will be inhibited based on the control

parameters settings to allow food temperature recovery.
