1. A storage cabinet apparatus, comprising:
- at least one storage cabinet compartment having an opening for access to the cabinet compartment;
a first sensor positioned within the storage cabinet to have a first zone of sensing; and
a second sensor positioned within the storage cabinet to have a second zone of sensing;
wherein, compared to the second zone of sensing, the first zone of sensing is closer to the opening of the storage cabinet compartment; and
wherein the first sensor and the second sensor are configured to sense an inventory item in the first zone of sensing and the second zone of sensing respectively.

Abstract
A supply cabinet is fitted with an outer sensor and an inner sensor. The outer and inner sensor wirelessly sense inventory items tagged with radio frequency tags and in proximity of the sensors. A method of tracking inventory items stored in a supply cabinet includes determining, based on time sequencing of sensing by the outer and the inner sensor, if an inventory item was removed from the cabinet or stored into the cabinet, and updating an inventory database accordingly. An alarm is optionally triggered if an inventory item is removed by an unauthorized user.

11. A method of tracking inventory of items stored in a supply cabinet, the method comprising:
-
receiving, at a processor, a first sensing message from a first sensor and a second sensing message from a second sensor that is spaced apart from the first sensor; and updating, at the processor, an inventory database for items in the supply cabinet; wherein said updating is responsive to time instants of sensing the inventory item at the first sensor and the second sensor. - View Dependent Claims (12, 13, 14, 15, 21)

16. A secure storage apparatus for storing a plurality of inventory items, the secure storage apparatus comprising:
-
a supply cabinet with a door; a first sensor positioned inside the door; a second sensor positioned between the door and the first sensor; and a processor communicatively coupled with the first sensor and the second sensor; wherein the first sensor and the second sensor are configured to sense proximate inventory items and communicate corresponding sensory messages to the processor; wherein the processor is configured to; restrict a user'"'"'s ability to open the door; determine, based on sensory messages received from the first sensor and the second sensor, if a predetermined inventory item was removed; and issue an alarm if the user opening the door was not authorized to remove the predetermined inventory item. - View Dependent Claims (17, 18, 19, 20)
