A polyhedral module device includes a body having multiple outer faces; a plurality of outer electrical contacts on at least one outer face of the body; an internal circuit mount disposed in the body; a specific-purpose internal circuit mounted on the mount; a switch network disposed in the body, the network having a plurality of switches, connections between the plurality of switches in the network being flexible; and a switch controller configured to change the connections between the plurality of switches, wherein the change of the connections between the plurality of switches by the switch controller changes connection paths between the outer electrical contacts and the internal circuit.

An exterior display system can be configured and arranged around a structure. The exterior display system includes a mechanical supporting structure configured and arranged about the exterior surface of the structure. This mechanical supporting structure can include various supporting structures and/or mounting structures which are configured and arranged to form a mechanical lattice framework. An electronic visual display device can be connected to the mechanical lattice framework to form the exterior display system. The electronic visual display device can include multiple electronic visual display panels which are connected to the mechanical lattice framework. Each of these multiple electronic visual display panels can include multiple groups of multiple light-emitting diodes (LEDs), also referred to electronic LED disc assemblies, that are configured and arranged in a series of one or more rows and/or a series of one or more columns.

A foldable display apparatus for minimizing stress applied to a bending area of a display panel. The foldable display apparatus can include a display panel configured to include a display area which includes a first display area, a second display area, and a bending area which is defined between the first and second display areas, a housing configured to include a first housing member, which supports a first area of the display panel corresponding to the first display area, and a second housing member which supports a second area of the display panel corresponding to the second display area, and a hinge part connected between the first and second housing members, and configured to enable the display panel to be folded or unfolded with respect to the bending area.

The invention relates to a module arrangement (1) with a base module and at least one submodule (5); the base module has at least two connection modules. The submodule (5) can be put into contact via a connection module with a choice of one of the connection modules of the base module and can consequently be attached to the base module in different orientations. Detection devices for detecting the orientation of the submodule (5) attached to the base module are provided in the base module.

A display apparatus includes a first base plate, a second base plate coupled to the first base plate to allow the second base plate to be rotated on the basis of a rotation axis between the first base plate and the second base plate, a moving plate coupled to the second base plate and configured to slide along a first direction with respect to the second base plate, a pop-up plate configured to move along a second direction corresponding to a thickness direction of the second base plate on the second base plate in accordance with a movement of the moving plate, and a display panel including a first portion coupled to the first base plate and a second portion coupled to the moving plate.

An electronic sign having slotted frame cabinets whereby each slotted frame cabinet can conveniently be attached to one or more vertically or horizontally positioned adjacent slotted frame cabinets by using connecting components which are generally located around the periphery of one or more slotted frame cabinets. Connecting components, including splice bars, splice plates, and mounting clamps, are aligned in, positioned along and secured to backing bars which are co-located in backing bar slots in one or more of the slatted frame cabinets. Lift eyes can be variably located in one or more lift eye slots. The use of externally located connecting components, which do not extend through the cabinetry, minimize the entry of environmental elements into the interior of the electronic sign. Multiple slotted frame cabinets can be connected without the removal of LED display panels.

The present invention provides methods and systems for a modular alert system that includes at least two modules having a top portion and a bottom portion. The modules provide an alarm for one or more monitored conditions, and the bottom portion and the top portion of one module contains mating features. A mounting plate that has a top portion and a bottom portion contains mounting features, and the mounting features of the bottom portion correspond to the mounting features of the top portion of one module for forming a selectively secured arrangement. The system may also include at least one speaker housed within the module, and a smoke detector.
