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 system and method for dynamically tracking and capturing content and displaying the content on public or semi-public non-personal digital displays. In exemplary embodiments, the content may include an urgent notification that is displayed within a slot of looped content with the manner in which the urgent notification is displayed depending on the level of urgency and attributes of the non-personal digital displays.

An illuminated signage has a housing that carries a plurality of signage panels having a photoluminescent area carrying indicia for the signage. The signage panels are carried in a channel extending across a front face of the housing. An electrical circuit controls a plurality of light emitters that are configured to illuminate when the photoluminescent area has been depleted and is no longer producing enough luminescence to illuminate the indicia. The electrical circuit may also be configured to illuminate the LEDs on demand.

An electronic signage assembly for creating and wirelessly posting messages to a display unit includes a display unit comprising a display transceiver and a control unit comprising a remote transceiver, so that the control unit is positioned for wireless communication with the display unit. The display unit also comprises a display screen. The control unit comprises an entry module, which allows for entry of a message. The remote transceiver is positioned to communicate the message, via the display transceiver, to the display screen for display of the message to persons proximate to the display unit.

In exemplary embodiments, the content may include an urgent notification that is displayed within a slot of looped content with the manner in which the urgent notification is displayed depending on the level of urgency and attributes of the non-personal digital displays.

A location-based and preference-based system and method for matching media content about persons, places and things with the expressed preferences of mobile users to notify users about and provide users with access to media content about persons, places and things that match the user's expressed preferences. The system thus provides information such as stories or articles that match the user's interests and relate to their location. The system may assign ranks to all of the media content that meets that user's preferences wherein, in one embodiment, it will automatically play them in the assigned order. Comparison of the user's preferences with the various profiles of the media content allows the user only to be informed of the media content for those persons, places or things that the user is likely to be interested in. The system and method thus provides for a mobile real-time point of interest exchange network.

The present invention discloses a layered electro-magnetic refreshable braille display device and braille reader. The layered electro-magnetic refreshable braille display device includes three layers of braille display modules and a touch panel. Each braille display module includes 5 plates and a plurality of tactile pin driving mechanisms for driving the “up” and “down” of the braille dots. One or more lines of braille cells are arranged on the touch panel. Each line of braille cells displays a plurality of braille characters. A microprocessor is connected to a braille translation module, a voice playing module and an interaction controller respectively, wherein the interaction controller is connected to the braille display device, to form the braille reader. This device can display one or more lines of braille characters by relying on the electro-magnetic principle. It boasts real-time refreshing of the braille, synchronization of braille display and voice playing.
