Abstract: A high-speed signal measurement system includes a printed circuit board and a measurement device. The printed circuit board includes a conductive pad. The measurement device is configured to be removably coupled to the printed circuit board. The measurement device is configured to establish an electrical connection between a conductive probe tip and the conductive pad. The measurement device includes a clamp movable between an open position in which the measurement device is configured to removably receive the conductive probe tip and a closed position in which the measurement device is configured to retain the conductive probe tip. The measurement device further includes a spring mechanism configured to exert a spring force to maintain the electrical connection between the conductive probe tip and the conductive pad when the measurement device is coupled to the printed circuit board and the clamp is in the closed position.

Abstract: An electronic component includes a first trace configured to transmit a first signal and a second trace configured to transmit a second signal. The electronic component further includes a layer of conductive material separated from the first and second traces by a layer of insulative material. The electronic component further includes a first vertical wall formed in direct contact with the layer of conductive material. The electronic component further includes a second vertical wall formed in direct contact with the layer of conductive material. The second vertical wall is separated from the first vertical wall by a void, and the void extends between the first trace and the second trace.

Abstract: According to one embodiment of the present invention, a computer-implemented method for autocorrelation based security monitoring and detection is disclosed. The computer-implemented method includes determining that input signal data transmitted to a white noise generator autocorrelates with itself at one or more time lags. The computer-implemented method further includes, responsive to determining that the input signal data transmitted to the white noise generator autocorrelates with itself at one or more time lags, determining whether an autocorrelation in the input signal data transmitted to the white noise generator matches one or more predetermined input signal data patterns associated with a known event or individual.
