    摘要： CAN bus signal format inference includes: extracting candidate signals from training CAN bus message traffic; defining one or more signals, each signal being a candidate signal that matches structural characteristics of a matching data type and each signal being assigned the matching data type; and generating an inferred CAN bus protocol with which the defined one or more signals conform. Signals are extracted from CAN bus message traffic using the inferred CAN bus protocol, an anomaly in an extracted signal is detected, and an alert is generated indicating the detected anomaly. In another aspect, a transport protocol (TP) signal is extracted and analyzed to determine a fraction of the TP signal that matches opcodes of a machine language instruction set, and an anomaly is detected based at least in part on the determined fraction exceeding an opcode anomaly threshold.

    摘要： Organism monitoring devices and organism monitoring methods are described. According to one aspect, an organism monitoring device includes a housing configured to be physically associated with an organism to be monitored, an antenna, signal generation circuitry comprising an oscillator configured to generate an oscillation signal, and an output node configured to output the oscillation signal, impedance matching circuitry coupled with the housing, the antenna and the signal generation circuitry, and wherein the impedance matching circuitry is configured to match an impedance of the signal generation circuitry and an impedance of the antenna, and wherein the impedance matching circuitry is further configured to receive the oscillation signal and to provide the oscillation signal to the antenna, and wherein the antenna is configured to emit a wireless signal externally of the organism monitoring device as a result of the provision of the oscillation signal to the input of the antenna.

    摘要： This document describes systems and techniques for a control system for a grid-forming inverter. In aspects, a reactive power current-limiting subsystem, based on a measured reactive power, is configured to generate a first signal representing a magnitude of a modulation waveform presentable to a pulse-width modulator configured to direct transistors in the inverter of the grid-forming inverter. An active power current-limiting subsystem, based at least in part on a measured active power, is configured to generate a second signal representing a rotating phase angle of the modulation waveform presentable to the pulse-width modulator. The reactive power current-limiting subsystem and active power current-limiting subsystem are configured to cause an alternating current (AC) output of the grid-forming inverter to resume a nominal form subsequent to current being directed around one or more transistors in an inverter to prevent an excessive output current from flowing through the one or more transistors.

    摘要： A modular radio frequency (RF) device includes N base units, each including a differential segmented array (DSA) tile with a support board and a two-dimensional (2D) array of electrically conductive tapered projections disposed on the support board. Neighboring pairs of the electrically conductive tapered projections form RF pixels. The N DSA tiles are arranged to form an RF aperture. The N base units are programmed to switch the RF aperture between a first operating mode and a second operating mode. In the first operating mode, the N base units are operated as at least two independent subsets with each subset operating as an RF transmitter or receiver independently of the other subsets. In the second operating mode all N base units coherently combine as a single phased array RF transmitter or receiver.
