Abstract
A self-powering tamper detection system architecture includes a power source, a tamper detector configured to identify a tamper event, a tamper switch electrically connected to the power source and mechanically connected to the tamper detector, a tamper controller configured to produce a tamper response when the tamper event is identified, and program memory configured to store program data. The tamper detector is configured to mechanically actuate the tamper switch when a tamper event occurs, and the tamper response provides a disruption of the program data. The tamper detector and the tamper switch can include printed circuit board and embedded transformer, whereby the embedded transformer includes an axially-moveable ferromagnetic core.

14. A method of using a self-powering tamper system architecture comprising a power source, a tamper detector configured to identify a tamper event, a tamper switch electrically connected to the power source and mechanically connected to the tamper detector, a tamper controller configured to produce a tamper response when the tamper event is identified, and program memory configured to store program data, the method comprising the steps of:
-
monitoring, with the tamper detector, for a mechanical movement indicative of a tamper event; mechanically actuating the tamper switch when an indicia of the tamper event occurs, to cause transmission of an electrical signal from the power source to the tamper controller when the indicia of the tamper event occurs; producing, with the tamper controller, a tamper response when the tamper event occurs; and disrupting, with the tamper controller, the program data when the tamper response is produced.

15. A self-powering tamper detection system, comprising:
-
a power source; a tamper detector, comprising a moveable ferromagnetic core; a tamper switch, comprising; a printed circuit board, having an aperture therein; an embedded transformer, including; a chassis strut, disposed perpendicularly to the printed circuit board; a circular primary winding, encircling the aperture; one or more circular secondary windings, encircling the aperture; and a moveable ferromagnetic core, configured to move axially within the chassis strut, thereby passing through the aperture; and an oscillator, configured to produce a time-varying voltage waveform; a driver, configured to apply the time-varying voltage waveform to the circular primary winding, thereby inducing a time-varying voltage waveform in each of the one or more circular secondary windings when the moveable ferromagnetic core magnetically couples the primary winding to each of the one or more circular secondary windings to produce an induced time-varying secondary voltage; a decoder, configured to produce a periodic signal representative of the induced time-varying secondary voltage; a timer, configured to; produce a first output when the periodic signal is present; and produce a second output when the periodic signal is not present; a tamper controller, configured to produce a tamper response when the tamper event is identified; and program memory, configured to store program data; wherein; the moveable ferromagnetic core is configured such that a tamper event causes the moveable ferromagnetic core to move axially within the chassis strut; the second output is indicative of the tamper event; and the tamper response comprises a disruption of the program data. - View Dependent Claims (16, 17, 18, 19, 20)
