Disclosed are a method and/or an apparatus of a foldable-reinstallable wireless warning system for transporting oversize loads. The system includes a transmitter unit, a towing receiver unit, a foldable banner, a battery enclosure, and a set of surface mounted lights. The transmitter unit is configured to transmit an encoded signal. The towing receiver unit is separate from the transmitter unit and is configured to receive and communicate the encoded signal to a radio receiver. The foldable banner has an oversize load warning message printed thereupon. The battery enclosure and the set of surface mounted lights are stitched onto the foldable banner. The radio receiver, a lithium-ion battery and a strobe light controller are housed in the battery enclosure. The set of surface mounted lights includes stop tail turn lights, strobe lights and D.O.T. lights.

The purpose of the present invention is to provide a magnetic fluid display in which a magnetic fluid moves in response to a magnetic field and which may display a unique visual image according to the meeting and parting of the magnetic fluid. A magnetic fluid display according to the present invention comprises: a display unit including a transparent liquid into which a magnetic fluid is injected; and a magnetic field generating unit for applying a magnetic field to the magnetic fluid at a rear surface of the display unit. When the magnetic field is applied, the magnetic fluid moves in the transparent liquid in a directional manner, so that an image may be displayed on the display unit.

A signage control system comprises: a primary estimation circuitry to use signage-side images and surveillance-side images to estimate a person feature, attributes and behavior of each person captured in these frame images; a storage device to associate and store results of estimations of the person feature, the attributes and the behavior of each specific person; an estimation result linkage circuitry to use the person feature stored in the storage device to link the results of estimations based on the frame images from multiple ones of the cameras for the same person so as to generate a group of estimation results for each person; and a content change circuitry to change a content displayed on the signage to another based on the attributes of each person expected to be in a position where such person can visually recognize the content on the signage, and based on preceding behavior of such person.

An identification system for providing information regarding an associated object (5), the system comprising a carrier (3) which is provided to the object (5), and display circuitry (7) which is provided to the carrier and displays information regarding the object (5).

A flexible display screen system and method includes an article that has a flexible material configured to cover at least a portion of a person's anatomy or at least a portion of an object. At least one flexible display screen is secured on the flexible material. A computer system is configured to provide image information for controlling a display of images on the flexible display screen. The computer system is configured to control the display of images on the flexible display screen in response to the sensor signal. The sensor may sense flexing of the flexible display screen or flexible material. Alternatively or in addition, the flexible display screen or flexible material may be controlled to flex, in response to the images displayed on the flexible display screen.

A display unit includes a transparent or translucent layer with a display side and a rear side, with an opaque or semitransparent layer on the display side, containing a plurality of apertures, a plurality of illuminants which are present at, or at a distance from, the rear side of the transparent or translucent layer, at least partly embedded in the layer, wherein at least one illuminant is substantially behind one of the apertures in each case configured and designed to emit light in the direction of and through the aperture, a transparent or translucent lamination ply adjoining the opaque or semitransparent layer and covering the plurality of apertures, and a transparent or translucent protective layer adjoining this lamination ply. Also disclosed are a display apparatus and a traffic guidance system comprising such a display unit, and use of the display unit as a media energy façade or a daylight display.

Disclosed is a display module including a transparent display panel and a frame to fix a side of the transparent display panel, wherein the frame has a communication unit to receive data from the outside, a controller to process the received data and to output a drive command corresponding to the processed data and a display drive unit to drive the transparent display panel in response to the drive command from the controller. A display system includes a system body and a display module detachably mounted in the system body.
