Abstract: A steer-by-wire steering system for a vehicle includes a bar extending from a first end to a second end, the bar defining a first groove and a second groove within an outer surface of the bar. The steer-by-wire steering system also includes an anti-rotation cartridge comprising a sleeve containing separate wear plates in which a plurality of ball bearings roll, wherein a first end of the sleeve contains a sleeve groove and window features, the inner surface of the sleeve containing V-shaped grooves in which the wear plates are disposed.

Abstract: A passive microwave component with constant impedance and electrically adjustable phase length utilizes a microstrip or stripline transmission line geometry incorporating a composite dielectric having both ferroelectric (FE) and ferromagnetic (FM) properties. These properties can be varied with externally applied electric and magnetic fields such that the phase length (or electrical length) of the line can be varied without varying the characteristic impedance of the transmission line. Thus, the component can be electrically tuned without adversely affecting the impedance match. The component can be used in microwave devices such as phase shifters, frequency filters, directional couplers, power dividers and combiners, and impedance-matching networks.
