First Claim
Patent Images
1. A system for tamper detection of a package, comprising:
- a light detecting system for detecting when the package is opened; and
a system for generating an alarm if the package is opened more than once after it is initially closed to indicate that the package has been tampered with, wherein the light detecting system further comprises a photovoltaic cell, and wherein the system for generating the alarm further comprises;
an electronic circuit coupled to the photovoltaic cell;
a light emitting diode (LED) coupled to the electronic circuit for generating a visual alarm;
a capacitor coupled to the photovoltaic cell and the electronic circuit for temporarily powering the electronic circuit when the package is closed; and
a radio frequency identification (RFID) tag coupled to the electronic circuit for setting a state of the electronic circuit.

5. A package, comprising:
-
a light detecting system for detecting when the package is opened; and a system for generating an alarm if the package is opened more than once after it is initially closed to indicate that the package has been tampered with; wherein the light detecting system and the system for generating an alarm are embedded into a material forming the package, wherein the light detecting system further comprises a photovoltaic cell, and wherein the system for generating the alarm further comprises; an electronic circuit coupled to the photovoltaic cell; a light emitting diode (LED) coupled to the electronic circuit for generating a visual alarm; a capacitor coupled to the photovoltaic cell and the electronic circuit for temporarily powering the electronic circuit when the package is closed; and a radio frequency identification (RFID) tag coupled to the electronic circuit for setting a state of the electronic circuit;
wherein only the photovoltaic cell and the LED are visible within the package.
