Abstract:
1. A method of inhibiting access, the method comprising: determining that access to an item needs to be inhibited; positioning a thermal grill relative to the item such that the thermal grill provides a barrier against an individual engaging the item, the thermal grill having warm portions and cold portions interlaced with the warm portions, the thermal grill providing a barrier when activated by heating the warm portions and cooling the cold portions to create a temperature differential, the temperature differential between the heated warm portions and the cooled cold portions causing pain to the individual without causing physiological damage when the individual touches the thermal grill; and activating the thermal grill when the thermal grill is positioned relative to the item, the thermal grill being activated for an entire duration of time during which access to the item is to be inhibited such that the warm portions are always heated and the cold portions are always cooled during activation of the thermal grill.
