Abstract: Method for monitoring products in a refrigerator, wherein the refrigerator (1) comprises at least a compartment (2) for containing products (3), a door (4) adapted to close said compartment (2) and radio frequency transmission means (5) adapted to communicate with a plurality of transponders (6) associated with said products (3) to detect the presence of said transponders (6) into the compartment (2), each transponder (6) being able to send a specific identification code, the method comprises: detecting said transponders in static condition of closed door (C1), detecting said transponders during a time period (T1) which represents a dynamic phase of door opening (C2), detecting said transponders during a second time period (T2) which represents a dynamic phase of closing door (F2), comparing said transponders (6) detected in static condition (C1) and in dynamic condition (F1, F2), and their time events of detection for determining the transponders introduced and extracted, respectively, from the refrigerator

Abstract: Apparatus for monitoring items passing through an entry/exit opening in a delimited space, comprising: radio-frequency transmission means (2) adapted to communicate with a plurality of transponders associated with said items to detect the presence of the transponders in proximity of the opening, each transponder being adapted to transmit a specific identifier code, at least a pair of optoelectronic sensors (3, 4) arranged in series at said opening, each sensor (3, 4) being adapted to transmit a first signal identifying a condition of clear sensor, in which said sensor (3, 4) detects the opening as being clear, and a second signal identifying a condition of locked-on, i.e. engaged sensor, in which said sensor (3, 4) detects an item passing through said opening.
