An article for mounting from or against the ceiling is removably coupled to a base fixedly secured to the ceiling, by a person standing on the floor, supporting the article on an elongated rod, and thrusting the article against the base to couple the article and the secured base. The article is removed by inserting the rod into the article, exerting a force on the rod to uncouple the article from the base, and supporting the article on the rod as the article is lowered. The article is thus positioned on or hung from the ceiling, without being manually contacted by the person. The article may be used to mount other devices, such as a sign, smoke detector, etc. or may include such device as a part of the mount.

A large size display is transportable, being construed of multiple rigid segments containing light emitting diodes (LED's). The rigid segments are linked by hinges or cables so the display is flexible and can be rolled up for storage and transport. The display can be unrolled upward or downwards such as from a protective container, such as a canister or truss. The weight of the display on the linked hinges or the tensioned cables provides sufficient rigidity. Such cables, like a signal and power distribution bus, are connected to the rear of each rigid element. The display can be repaired by removing and replacing selected rigid segments from the front thereof.

An electronic display module having a four-point latching system for incorporation into an electronic sign and process where more than one latch mechanism can be actuated simultaneously to deploy to engage the mounting panel assembly of an electronic sign. Gear operated actuating arms incorporated in an overcenter arrangement position latch in opposing latch mechanisms to position latch arms outwardly in a linear direction over a mounting panel assembly followed by pivotal latch positioning to rotationally engage the latch arms against the mounting panel assembly to secure the electronic display module to the mounting panel assembly.

The disclosure concerns a light display panel with a matrix of pixels each comprising three monochrome electroluminescent diodes of three colors. The diodes are controlled by a control circuit delivering electrical power P to each diode, said electrical power being expressed in the form P-k.Pr, wherein Pr is a reference electrical power particular to the diodes of each color and k is a coefficient selected according to the display to be presented. Over the course of time the reference electrical power is subjected to different variations depending on the colors, to compensate for the aging of the diodes.

A remotely controlled electronic display sign which operates with a plasma display and which provides for humidity control and the like allowing the sign to be used in various environments. The sign is essentially self-contained and includes those components necessary for enabling a display of desired material from a remote control source. A controller in or associated with the sign is accessible either electrically, or through satellite transmission or other wireless transmission from the remote source which allows the display of the sign to be changed at will. Thus, an operator at a remote source may, with the aid of a pre-prepared graphic design, transmit that design to the controller at or associated with the sign for display of that graphic information.

A method of collaborative interactions with billboards includes receiving a request, by a billboard network manager, from an advertisement company to display synchronized interactive advertisements and video games on billboards in an area, inviting users in the area to participate in the advertisements and video games through the billboards and mobile devices of the users via a network, checking registration of the users to participate in the collaborative interactions with billboards, and checking a volume of the users in the area for appropriate synchronized advertisements and video games. If the volume of users is appropriate for synchronized advertisements and video games, then the billboard network manager displays the synchronized advertisements and video games, and continues to track the volume of the users in the area. If the volume of users is not appropriate for synchronized advertisements and video games, then the billboard network management reconfigures synchronized billboard content for more appropriate advertisements and video games by one of randomly changing a content, and propagating and extending through synchronized billboards a particular content of some billboard section that brought more interest from the users.

A flexible display unit and a mobile terminal having the same are disclosed. The flexible display unit includes a flexible display film, insulated flexible display unit edges formed at two opposite edges of the display film, and a plurality of electromagnets formed in the display unit edges at predetermined intervals. The two opposite edges of the flexible film are straightened by magnetic forces when the display film is unrolled to the outside of a main body of the mobile terminal. Accordingly, a problem of the flexible display unit not being flat or being distorted may be solved. Additionally, the flexible display unit of the present invention is smoothly rolled into the main body in the same manner as in a conventional flexible display unit, because the flexibility of the flexible display unit of the present invention is recovered by removing the magnetic forces when rolling the flexible display unit into the main body.

In an assembly of modules with magnetic anchorage for the construction of grid structures, one or more elements for stabilization of the grid structure are inserted in the form of panels (6, 12, 6″) which can be removably slotted in corresponding polygonal areas circumscribed by the modules of the grid structure.

A flexible display apparatus has a small thickness which makes it easy to wind or unwind a flexible display module. The flexible display apparatus includes a frame module, into or from which a flexible display module is wound or unwound, and a panel elevating module configured to vertically move the flexible display module via folding or unfolding of at least one retractable unit.

A bi-stable snap action ribbon spring incorporated into self-latching, spring-loaded mechanisms. The dual mode stability of the spring eliminates the need for complex latching mechanisms thereby simplifying the device manufacture and device reliability. The spring is stable in either a linear or coiled state enabling the simplified design of rolling, hinging and feeding mechanisms. A plan or map rolling and presentation device incorporates a bi-stable snap action ribbon spring along with optional spring end caps and stiffening elements. The plan or map is driven to a stable coiled or stable rolled shape by the influence of the snap action spring. Application of the snap spring properties to a discreet length of a longer ribbon can create a hybrid bi-stable hinge mechanism. A convenient storage container utilizes the bi-stable characteristics of a snap action ribbon spring to create a container having a self-closing and captured lid. A can or drum feeder incorporates the bi-stable characteristics of a snap action ribbon spring to provide a device that reliably stores and presents cans such as soda cans.

A light-emitting display system has an alignment mechanism to align or angle light-emitting tiles of the display. A first tile connects to a second tile by joining a first clamp portion on the first tile with a second clamp portion on the second tile. In an implementation, the alignment mechanism includes a replaceable angle adjustment insert that is inserted into at least one of the clamp portions, such as the first clamp portion. When the first and second clamp portions are joined, a surface of the second clamp portion presses against the insert and a desired angle between the first and second tile is formed. The insert can have any angle so that any desired angle can be formed between the first and second tiles.
