Method and apparatus for training email recipients against phishing attacks using real threats in realtime
An approach is proposed to support user-specific real time anti-phishing training of email recipients using real phishing attacks. When a recipient triggers an active content such as an URL link embedded in and/or opens an attachment to an email arrived at the recipient's account, the triggered active content is synchronously intercepted and examined in real time for potential malicious intent of a phishing attack. If the triggered active content is determined to be safe, the recipient is allowed to access the content. If the active content is determined to be malicious, the active content is blocked and the recipient is redirected a safe blocking mechanism. The recipient is then provided with an anti-phishing training exercise, which is specifically customized for the recipient based on the blocked active content in the payload of the email and/or the recipient's security posture and awareness. |

Resource manager for transaction processing systems
A resource manager (RM) instance is associated with each transaction processing system (TPS) member, of a TPS group. Each RM instance monitors performance of the associated TPS member. If a TPS member becomes unavailable for any reason (a failing TPS), the associated RM instance broadcasts status of the failing TPS to RMs associated “surviving” members of the group. RM instances associated with surviving members initiate a series of actions that reduce the resources used by the surviving TPS members. Consequently, the surviving TPS members are better able to process the additional workload imposed on them due to the unavailability of the failing TPS. Once the failing TPS is brought back online and made available again (or a replacement TPS is brought online), RM instances associated with the surviving members perform actions to undo the resource usage reduction tasks, and the TPS group returns to a nominal configuration. |

Threshold generation for coded ultrasonic sensing
In an ultrasonic detection system that uses frequency-modulation coding to distinguish emitted bursts from multiple transducers, a receiver associated with a transducer uses dynamic thresholding to discriminate valid echoes from system and environmental noise in multiple envelope signals produced by multiple correlators. The time-varying dynamic thresholds are generated from the mean of noise in a respective envelope derived from the output of a respective correlator. Multiple thresholds can be combined together such that a single time-varying threshold is applied to all correlators' envelopes. Such thresholding has the benefits of a constant false-alarm rate with regard to detection of echoes (as opposed to false triggering from noise), and, owing to finer-resolution and adaptive thresholds, can detect targets or obstacles as further distances and with greater time responsiveness. |

Triangular beam configurations for rapid beam alignment in 5G and 6G
In 5G and 6G, beam alignment remains an arduous, time-consuming process. Procedures are disclosed herein for rapid and efficient beam alignment, by configuring a phased-array antenna to emit a “triangular beam”, which is a wide beam that varies in angle from a high power at angle-1 to a low power at angle-2, with a ramp-like intensity variation in the region between the two angles. Then a second signal is emitted, with the triangular distribution reversed (higher power at angle-2). A receiver can then measure the as-received amplitudes from the two triangular beams, calculate the ratio of signal reception from the two beams, and thereby determine the alignment angle. In another version, the transmitter transmits two non-directional pulses, and the receiver detects them using a triangular sensitivity distribution versus angle. By either method, the devices can align their beams using just two triangle beam pulses, saving substantial time, resources, and background generation. |

Apparatuses and methods for passive fault monitoring of current sensing devices in protective circuit interrupters
Passive monitoring the integrity of current sensing devices and associated circuitry in GFCI and AFCI protective devices is provided. A protection circuit interrupter employs a capacitively coupled noise signal obtained by an arrangement of one or both of line side arms relative to a Rogowski coil. The noise signal is monitored while the line and load sides of a protective circuit interrupter are disconnected, and the connection of the line and load sides disabled if the noise signal fails to correlate sufficiently to a reference noise cycle. When the line and load sides are connected, the RMS value of the observed current signal is monitored such that the line and load sides are disconnected if the observed current signal fails to meet an RMS threshold. The observed current signal is compensated by subtracting the reference noise cycle prior to monitoring for the fault condition applicable to the protective device. |

Measurement system for characterizing a device under test
In a measurement system, a signal probing circuit may provide probed signals by probing voltages and currents and/or incident and reflected waves at a port of a device under test (DUT).

A signal processing circuit may then process the phase coherently digitized probed signals. |
