Abstract
An apparatus for detecting a condition or authenticity of one or more electronic devices includes an enclosure having an antenna integrated therewithin, a fixture mounted within a hollow interior of the enclosure, the fixture being configured to receive the one or more electronic devices and connect one or more signals to each of the one or more electronic devices and a sensor and controller assembly connected to the antenna and configured to process a signature of an emission of a radiofrequency (RF) energy from of one or more electronic devices having the one or more signals connected thereto.
Core Innovation
The invention provides an antenna enclosure for detecting counterfeit electronic devices and substandard electronic devices. The enclosure includes a base and a peripheral wall that defines a hollow interior and an access in the peripheral wall, and an antenna integrated into the enclosure to capture RF emissions related to an electronic device under test.
The enclosure includes a drawer mounted for movement to selectively open and close the access. The drawer is configured to mount a fixture on an interior surface of the drawer, and the drawer provides signal input connection, power input connection, and clock input connection on an exterior surface. The fixture/socket arrangement enables signal access while maintaining an enclosed RF environment around the electronic device.
A sensor/controller with a wideband RF receiver digitizes RF emissions and performs pattern analysis using automated detection algorithms. The emissions are compared to predefined baselines to classify devices as authentic versus counterfeit/substandard. The system applies controlled signals to drive internal circuitry so that intended or unintended RF emissions vary to enhance discrimination.
The disclosed embodiments further include fixture features intended to promote and suppress electromagnetic emissions, including RF transmission and layout features and controlled-impedance trace design features. Additional refinements add optional sensing and environmental conditions, such as temperature sensing and environmental RF shielding, with multiple enclosure shapes and automated testing approaches described in the document.
Claims Coverage
The provided independent claims define an antenna enclosure with an integrated antenna and a selectively sealing drawer/fixture interface, and define a fixture that interconnects power, ground, and a clock input/connection to a socket. Across the independent claims, the core inventive features focus on the integrated antenna enclosure structure, the drawer with access-opening selective sealing and exterior signal/power/clock inputs, and the fixture wiring structure for the socket including power, ground, and clock.
Antenna enclosure with base, peripheral wall access, integrated antenna, and selective drawer sealing
An antenna enclosure includes an enclosure comprising a base and a peripheral wall, a hollow interior and an access in the peripheral wall to the hollow interior; an antenna integrated into the enclosure; and a drawer mounted for a movement to selectively open and close the access, the drawer configured to mount a fixture on an interior surface of the drawer.
Signal input connection on exterior drawer surface
The antenna enclosure further includes a signal input connection on an exterior surface of the drawer.
Fixture for socket and connector with power, ground, and clock connection
A fixture includes a circuit board; a socket mounted on the circuit board; a connector mounted on the circuit board; a power connection between the connector and the socket; a ground connection between the connector and the socket; a clock input connector mounted on the circuit board; and a clock connection between the clock input connector and the socket.
Clock input connection on exterior drawer surface
An antenna enclosure includes a drawer mounted for a movement to selectively open and close the access, the drawer configured to mount a fixture on an interior surface of the drawer, and a clock input connection on an exterior surface of the drawer.
Power input connection on exterior drawer surface
An antenna enclosure includes a drawer mounted for a movement to selectively open and close the access and provides a power input connection on the exterior surface of the drawer.
Drawer-mounted fixture including circuit board, socket, connector, power/ground, and clock input/clock connection
An antenna enclosure includes a fixture mounted on an interior surface of the drawer, the fixture comprising a circuit board; a socket mounted on the circuit board; a connector mounted on the circuit board; a power connection between the connector and the socket; a ground connection between the connector and the socket; a clock input connector mounted on the circuit board; and a clock connection between the clock input connector and the socket.
Collectively, the independent claims cover an antenna enclosure architecture combining an integrated antenna with a drawer that selectively opens and closes a peripheral-wall access while carrying a fixture. The claims also define the fixture’s electrical connectivity between a connector and a socket for power and ground, and for a clock input/clock connection, with additional independent structure specifying exterior clock and power input connections on the drawer.
