Abstract: An antenna and an antenna system. The antenna includes: a first dielectric layer (1) having a first surface and a second surface, which are arranged opposite each other in a thickness direction thereof; a radiation patch (2), which is arranged on the first surface of the first dielectric layer; and a first electrode layer (3), which is arranged on the second surface of the first dielectric layer, and at least partially overlaps with the orthographic projection of the radiation patch on the second surface, wherein the first electrode layer has inner recesses (31, 32), and openings of the inner recesses face the radiation patch. The orthographic projection of at least part of a radiation edge of the radiation patch on the first dielectric layer at least partially overlaps with the orthographic projections of the inner recesses on the first surface.

Abstract: An air-handling system includes a housing having a passageway formed therethrough. A diverter is rotatably coupled to the housing, and includes a door disposed in the passageway for selectively opening and closing the passageway. A shaft of the door extends through a first opening of the housing, and extends outwardly therefrom, defining a first axis. A lever is coupled to the shaft of the diverter. A flexible tab is disposed axially outwardly of the lever and is positionable in a first position and a second position. In the first position, a distal end of the tab is positioned radially inwardly of an outer circumferential surface of the lever, and in the second position the distal end of the tab is positioned radially outwardly of the outer circumferential surface of the lever. The distal end is moveable about a second axis, parallel to the first axis.

Abstract: A blower wheel for use in a blower assembly is disclosed, wherein the blower wheel includes a hub, a concentrically arranged outer ring, and an array of spaced apart blades arranged on an outer periphery of the hub and extending between the hub and the outer ring. The hub includes a wave configuration formed therein. The wave configuration includes an annular array of crests and an annular of troughs alternately formed in at least one of an outer surface and an inner surface of the hub. The hub may also include an annular array of support members formed on the inner surface thereof.

Abstract: An attenuation device for a vehicle is provided, including a housing having a chamber formed therein. The housing is coupled to and in fluid communication with an air-conditioning circuit of the vehicle. A dampening member is disposed within the chamber of the housing. The dampening member includes a partition plate having at least one pipe disposed therein. The dampening member is configured to attenuate acoustic energy produced by a fluid of the air-conditioning circuit.
