Tamper detection device

A tamper detection device (100) configured to be affixed to a product for detecting unauthorized intrusion of the product, said device (100) comprising:

• a. at least one transducer (106, 110) configured to detect at least one tamper event, and further configured to generate at least one trigger signal upon detection of the at least one tamper event;
• b. a power supply unit (114);
• c. a logical gate (112) operable in states consisting of open state and closed state;
• d. a processing unit (104) in communication with said power supply unit (114), said processing unit (104) configured to receive power from said power supply unit (114), said processing unit (104) further configured to cooperate with said transducer (106, 110) and said logical gate (112) to generate a tamper detection signal for changing the state of said logical gate (112) upon the occurrence of an event selected from a group of events consisting of:
• i. receiving said trigger signal from said transducer (106, 100), and
• ii. detecting a cut-off of power supply from said power supply unit (114);
• e. a tamper tag (102) connected to said logical gate (112), said tamper tag (102) comprising a set of sensors (116) connected to said logical gate (112), said sensors (116) configured to detect at least one critical parameter corresponding to a change in the state of said logical gate (112) and generate a sensed signal, said tamper tag (102) further comprising an LED indicator (118) configured to communicate with said set of sensors (116), said LED indicator (118) configured to receive said sensed signal from said set of sensors (116), and further configured to indicate the state of the device (100);
• and
• f. an auxiliary capacitor (108) configured to supply power to said processing unit (104) in the absence of the supply of power from said power supply unit (114).
