Abstract: A system and method for detecting a rotary wing aircraft. A return electromagnetic signal, reflected by a rotary wing aircraft, is received through an electromagnetic signal detection apparatus. The aircraft includes a plurality of propeller blades attached to at least one motor. At least one propeller blade has at least one portion with a reflectivity different from other portions. A first time series data of the return electromagnetic signal is received. A second time series data is determined based on the first time series data and a predefined threshold. A characteristic of the second time series data is used to determine whether it corresponds to the known aircraft.

Abstract: A method and system for authenticating a device, board, assembly or system includes obtaining or processing test/scan information provided via extraction of ECID or other unique identifying information regarding a board. A re-authentication process is performed to verify that the board contains only legitimate ECID or other uniquely identified devices, via comparison of re-extracted codes of devices at known positions against a reference record, the reference record being established by an initial authentication process that utilizes information regarding authentic/unique ECID or other uniquely identified codes of devices delivered to populate the board to derive the reference record for the device.

Each switch circuit may not apply the corresponding constant current to the common output when the corresponding bit does not have the predetermined value. A common current may be applied at the common output to a spiking neuron circuit.
