Examples disclosed herein relate to detecting misalignment of a touch sensitive mat Examples include detecting corners of the touch sensitive mat, determining a set of reference corners, performing a comparison of the detected corners of the mat with the set of reference corners, and determining a level of misalignment based on the comparison.

An electronic device is provided in the present application, which includes a first component; a display arranged on a first surface of the first component; a second component, which includes a supporting body and a projector, the second component being arranged at a first lateral portion of the first component and the projector being arranged on the supporting body; and a connecting member arranged at the first lateral portion of the first component. The supporting body is movable with respect to the first component via the connecting member, the projector is rotatable with the rotation of the supporting body, and the projector moves to a second relative position with respect to the first component when the supporting body moves to a first relative position with respect to the first component.

A projector includes a projection lens and a projector body. In the projection lens, a U-shaped optical path is formed by optical axis to optical axis. A lens barrel is a U-shaped barrel. A housing of the projector body includes a storage section. The projection lens is supported rotatably about the optical axis with respect to the housing, in an up-down direction and a right-left direction of the housing perpendicular to the optical axis, between a first position where the projection lens is stored inside a storage section provided in the housing and a second position where the projection lens is protruding from the housing.

An in-flight entertainment system is disclosed. In various embodiments, the in-flight entertainment system includes a display having a viewing surface and a back surface opposite the viewing surface; and a projector connected to the display and configured to illuminate the viewing surface.

Improved corners for overhead frames having primary and secondary fasteners that are located within the distal rectangular periphery of alpha oriented overhead frame components so that the width of bundled overhead frames is reduced; protrusions leading to snagging are eliminated; obstructions to the preferred, industry-wide, disassembled frame orientation are precluded; and frame components may be rigidly bundled into the alpha orientation without the wasteful and time-consuming use of temporary materials.
