Abstract: A pulsed-power driver with modular construction is presented. The pulsed-power driver includes a voltage adder assembly and a transmission line that extend along a driver axis from an upstream end to a downstream end. The voltage adder assembly has a modular construction and is disposed around the transmission line. The voltage adder assembly includes a number of stages axially distributed along the driver axis. The transmission line includes an inner conductor and an outer conductor. The outer conductor includes a modular segmented construction along the driver axis that includes a number of outer conductor segments corresponding to the number of stages. The pulsed-power driver further includes a plurality of stage insulators longitudinally interleaved between each pair of adjacent outer conductor segments, and the outer conductor segments of each pair are electrically connected to each other in series via a corresponding stage of the voltage adder assembly.

Abstract: An apparatus has a Radio Frequency (RF) signal generator to produce RF signals phase shifted relative to one another in accordance with RF frequency waveform parameters. Amplifier chains process the RF signals to produce channels of amplified RF signals. Each amplifier chain has amplifiers and at least one amplifier has a tunable gate voltage synchronized with the RF signals.

Abstract: A retractable tooth bucket configured to provide both digging and grading functionality on a worksite. The retractable tooth bucket has a bucket joined to a first bracket and a second bracket. A first pivot frame joined to the first bracket. A second pivot frame is joined to the second bracket. A first and second mounting brackets are joined to the bucket. A cylinder is joined to the hydraulic ram, and the first and second pivot frames. A hydraulic fluid line is joined to the hydraulic ram. Three cross members are joined to the first and second pivot frames. Five spines are joined to the third cross member and arranged against a pivot pin. Engaging the hydraulic ram causes spines to extend away from the bucket.

Abstract: Provided herein are systems and methods for training, maintaining and using skills for shooting a target with a projectile. More particularly, the invention relates to virtual and/or augmented reality, augmented reality, mixed reality and consensual reality systems and methods to train and maintain shooting skills in military, law enforcement, competition and sporting settings, environments and missions.

Abstract: An array of antennae includes a monobit transmitter to insert dither into a transmit signal to form a dithered transmit signal. Monobit receivers process received signals that are combined with the dithered transmit signal to form composite received signals. Digital down converters process the composite received signals to form down converted received signals. A beamformer circuit processes the down converted received signals to form recovered signals.

Abstract: A bicycle training wheel assembly that allows riders to lean from side to side, thereby enabling the rider to practice balancing skills. The bicycle training wheel assembly has adjustable maximum tilt settings that train the rider in increments as they learn to balance on a bicycle. An omnidirectional wheel accommodates lateral rotational components to prevent skidding of the wheel when the bicycle is tilted towards or away from a training wheel assembly.

Abstract: A steam generator includes a lower integrated tubesheet and plenum (ITP) configured to receive feedwater and a first set of heat transfer tubes fluidly coupled to a plurality of stubs protruding from a first side of the lower ITP. A second set of heat transfer tubes fluidly couples to plurality of stubs protruding from a second side of the lower ITP. The first set of heat transfer tubes is coiled in a substantially clock-wise direction, and the second set of heat transfer tubes is coiled in a substantially counter-clockwise direction. The steam generator further includes an upper ITP fluidly coupled to the first and second set of heat transfer tubes, wherein the feedwater entering the lower ITP is converted to steam in the first and second sets of heat transfer tubes. The upper ITP is configured to transport the steam away from the steam generator.

Abstract: The invention relates to a device, comprising a camera unit, which is used to record images of the exterior area of a motor vehicle, and a cover element, which can be moved from a closed position to an open position by means of a drive, wherein the camera unit is behind the cover element and inaccessible from outside in the closed position of the cover element and images can be recorded in the open position of the cover element. For this purpose, the cover element has an outer surface facing away from the camera unit, and the drive interacts with a mechanism in such a way that the outer surface is always in the exterior area of the motor vehicle in each position of the cover element during the movement of the cover element between the closed position and the open position.
