Abstract: A changing table comprises a wall assembly and a tray assembly. The wall assembly is capable of mounting to a wall, and the tray assembly is pivotally attached to the wall assembly such that the wall assembly and tray assembly form a changeable angle ? in between them. The tray assembly comprises an exterior first surface and an interior second surface. The interior second surface comprises a cushion and is configured to receive an infant.

Abstract: A changing table comprises a wall assembly and a tray assembly. The wall assembly comprises wall housing, a transparent-to-UV-light panel, and a UV light source. The wall assembly and tray assembly form a changeable angle ? in between them. The tray assembly comprises an exterior first surface and an interior second surface. The second surface is configured to receive an infant and at least a portion of UV light generated by the UV light source.

Abstract: A changing table includes a wall assembly and a tray assembly. The wall assembly includes a transparent panel, a reflector, and a UV light source disposed in between. The tray assembly is pivotally attached to the wall assembly, forming a changeable angle ? in between. The tray assembly includes a front panel and a cushion layer. The cushion layer forms a concaved surface that receives an infant. The concaved surface receives UV light generated by the UV light source.

Abstract: A system, including: a power source, a multi-layer device, and an electronic controller. The multi-layer device is connected to the power source and has two sides: a viewing side and a second side opposite the viewing side. The multi-layer device permits or prevents light to pass therethrough from the second side toward the viewing side. The multi-layer device includes: a coloring layer group having a plurality of pixels, each pixel having at least three sub-pixels corresponding to different colors; and a shutter layer group having a unique subpixel shutter corresponding to each sub-pixel of the coloring layer group. The electronic controller is connected to the power source and the multi-layer device, and is adapted to control each sub-pixel shutter to selectively permit or prevent passage of an amount of light therethrough; and control each combination of sub-pixel shutter and corresponding coloring layer sub-pixel to produce pixels on the viewing side that can be any of opaque black.
