Abstract: A lubricant composition including: from 70 to 99.99% of at least one base oil and from 0.01 to 30% of at least one alcohol ethoxylated phosphate ester compound of formula (I): wherein R is a linear or branched alkyl group having from 10 to 14 carbon atoms, m is an integer from 1 to 3, preferably from 1 to 2, n is an integer superior or equal to 6. Also, the use of the compound of formula (I) to prevent and/or reduce and/or limit and/or delay corrosion and/or tribocorrosion of the metal parts of a combustion engine.

Abstract: An improved phase shifter assembly is provided. The phase shifter assembly may comprise first and second sub-assemblies with certain common actuating elements. In one example, a first phase shifter sub-assembly is provided, the first phase shifter sub-assembly including a first phase shifter carrier, a first phase shifter printed circuit board mounted on the first phase shifter carrier, a first wiper printed circuit board coupled to an input of the first phase shifter printed circuit board and having at least a first end coupled to transmission lines on the first phase shifter printed circuit board, and at least one wiper support mechanically coupling the first wiper printed circuit board to the first phase shifter printed circuit board. A second phase shifter is similarly provided. Common actuating elements may include a pivot arm and a throw arm.

Abstract: A panel antenna having an enclosure, an internal cover, one or more micro radios and RF modules, and a radome is provided. The enclosure may include a rectangular rear panel, side walls with an interior surface to mount micro radios and an external surface to receive heat sinks, and a hinged front cover providing an internal cover. The internal cover may also have a plurality of RF radiating modules fastened thereto. The internal cover may also provide environmental sealing and electromagnetic shielding. The plurality of micro radios are located inside the cavity of the enclosure, and each micro radio is coupled to an RF radiating module. The micro radios may be mounted inside the enclosure on the side walls. The radome encloses the RF radiating modules. The radome may be mounted to the internal seal. Additionally, the panel antenna may further include a heat sink mounted on an exterior side of the rear panel.
