Disclosed are embodiments of display modules, assemblies of display modules, and systems of display modules. Display modules have a plurality of light emitting elements arranged in a predetermined pattern and providing a highly uniform visual effect. Alignment and complementary alignment features enable the alignment of adjacent display modules and the creation of large displays from a plurality of aligned display modules. Features to grip and retain a support frame are provided. Modules and systems have features that permit installation and removal from the front side of the display. A system of modular support frames works cooperatively with the display modules, adapting to different mounting environments, and thereby providing large modular displays with desirable properties.

A container sleeve apparatus includes an arcuate or cylindrical body that can be positioned on a cylindrical or conical container, such as a tumbler, cup, can or bottle. A transparent or translucent insert section that can be releasably attached to the sleeve body. The sleeve body can be made of a non-slip, elastic material, such as neoprene rubber. The insert section can be made of plastic, and can include a logo printed or engraved thereon. The apparatus can include a light emitting device that illuminates the transparent/translucent insert section.

An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal.

An improved illuminable card includes a carrier layer, first and second contact pads, or rails, supportably interconnected to the carrier layer to receive a power signal, and an illuminable patch supportably interconnected to the carrier layer or another carrier layer for electrical coupling with the first and second contact pads and illumination upon receipt of a power signal at the first and second contact pads. The illuminable card may include a mask overlying at least a portion of the illuminable patch and having a predetermined pattern a to define a predetermined image visible on a side of the illuminable card upon illumination of the illuminable patch.

A veneer for a wall-mounted keypad may include indicia that are laser cut therethrough and that are representative of functions that may be performed by the keypad. The veneer may include a recess that extends into an inner surface of the veneer, proximate to the indicia. The recess may be shaped such that a perceived aesthetic of an outer surface of the veneer is preserved during formation of the indicia. The recess may for example have an organic shape defined by a curved outer perimeter that does not define any corners.
