Abstract: A testing apparatus for electromagnetically sensitive equipment includes a housing defining a testing chamber. The housing blocks transmission of electromagnetic waves from an external environment into the testing chamber and reduces reflection of electromagnetic waves within the testing chamber. The testing apparatus also includes a tube defining an air flow path between the testing chamber and the external environment. The tube blocks transmission of electromagnetic waves from the external environment into the air flow path. The tube includes a proximal end coupled to an opening in the housing such that the air flow path is fluidly coupled to the testing chamber via the opening, a distal end opposing the proximal end, and a bent segment extending between the proximal end and the distal end.

Abstract: A head-mounted device may have a head-mounted housing that is configured to be worn on a head of a user. While the head-mounted device is being worn, left and right displays in optical modules in the head-mounted device may provide images to eye boxes located rearward of the head-mounted device. A forward-facing publicly viewable display on a front portion of the head-mounted device may be covered with a transparent housing portion forming a display cover layer. A dielectric member having a ring-shaped edge portion surrounding the publicly viewable display may be mounted under a corresponding edge portion of the display cover layer. A flexible printed circuit antenna with compound curvature may be laminated to the edge portion of the dielectric member.

A forward-facing display on a front portion of the head-mounted device may be covered with a transparent housing portion forming a display cover layer. An antenna may be mounted in the device. An antenna support member may be coupled to the head-mounted housing. A biasing member such as a layer of foam may have first and second opposing surfaces characterized by surface normals. The foam may be characterized by an axis of preferential compression that is not parallel to the surface normals. The support member may press against the foam so that the antenna presses against an edge portion of the display cover layer or other overlapping dielectric layer.

While the head-mounted device is being worn, optical modules in the head-mounted device may provide images to eye boxes located rearward of the head-mounted device. A forward-facing display on a front portion of the head-mounted device may be covered with a transparent housing portion forming a display cover layer. An antenna may be mounted in the device. A curved portion of the display cover layer or other dielectric housing layer may overlap the antenna. The antenna and/or other components may be formed by contouring a flexible printed circuit into a shape characterized by a surface with compound curvature. The contoured flexible printed circuit may have polymer layers and a metal trace between the polymer layers. A neutral stress plane may be aligned with the metal trace.
