A beam steering system includes a differential segmented array (DSA) antenna comprising a plurality of pyramid structures and elements arranged in an array comprising a first and second set of direction elements, where each element is defined between opposing faces of two adjacent pyramid structures and a position of each element is located at a distance from a common origin of the elements of the array; phase gradient determination circuitry to determine a first and second phase gradient for the direction elements, where the phase gradients are based on a first and a second angle of a target with respect to the DSA antenna, and an operating frequency of the DSA antenna; and phase shift determination circuitry to determine a first and second phase shift, for each of the elements, and to determine a resultant phase shift, for each element, by summing the respective first and second phase shifts.

Beam steering and direction finding for a differentially segmented aperture antenna

A radio frequency (RF) aperture includes an array of electrically conductive tapered projections arranged to define a curved aperture surface, such as a semi-cylinder aperture surface, or a cylinder aperture surface (which may be constructed as two semi-circular aperture surfaces mutually arranged to define the cylinder aperture surface). The RF aperture may further include a top array of electrically conductive tapered projections arranged to define a top aperture surface. The top aperture surface may be planar, and a cylinder axis of cylinder aperture surface may be perpendicular to the plane of the planar top aperture surface. The RF aperture may further include baluns mounted on at least one printed circuit board, each having a balanced port electrically connected with two neighboring electrically conductive tapered projections of the array and further having an unbalanced port.

Conformal/omni-directional differential segmented aperture

A broadband RF imaging device includes a broadband RF aperture array, at least one RF receiver, and a computer. The at least one RF receiver has short RF connections with the broadband RF aperture array, e.g. length 10 meters or less. The computer has a digital data connection to the at least one RF receiver. Each RF receiver is configured to receive broadband RF signal data over a sampling time interval from the broadband RF aperture array, and to digitize the broadband RF signal data to generate digitized broadband RF signal data, and to store the digitized broadband RF signal data locally at the RF receiver. The computer receives the digitized broadband RF signal data stored locally at the at least one RF receiver, and is programmed to reconstruct an RF image from the digitized broadband RF signal data received from the at least one RF receiver.

A fuel processing system and method for a sulfur bearing fuel include a hydrodesulfurization reactor followed by an adsorbent bed for removing sulfur or sulfur containing species from the fuel. In certain embodiments, the adsorbent bed is a ZnO bed. In another embodiment, a fuel processing system and method for a sulfur bearing fuel include a steam reformer, a hydrodesulfurization reactor, and an adsorbent bed.

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.

A radio frequency (RF) aperture includes an interface board. An array of electrically conductive tapered projections have bases disposed on a front side of the interface printed circuit board and extend away from the front side of the interface printed circuit board. RF circuitry is disposed at the back side of the interface board and is electrically connected with the electrically conductive tapered projections.

Systems and methods for signal communication with scalable, modular network nodes

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.

CAN bus protection systems and methods

An air interface plane (AIP) of a radio frequency (RF) aperture includes: a circuit board having a first side and a second side opposite the first side; and a matrix of tapered elements arranged on the first side of the circuit board and secured to the circuit board, the matrix of tapered elements cooperating to at least one of receive or transmit an over-the-air RF signal. Suitably, each tapered element of the matrix has: a central hub extending along a longitudinal axis from a hub base which is proximate to the first side of the circuit board to an apex of the tapered element which is distal from the first side of the first circuit board; and a plurality of arms extending from the central hub at the apex of the tapered element, each of the plurality of arms including a first portion that projects the arm radially away from the longitudinal axis and a second portion that projects the arm longitudinally toward the first side of the circuit board.
