An article display stand includes a first supporting part configured to support an aerial vehicle body of an aerial vehicle and a second supporting part configured to support a control terminal of the aerial vehicle.

A system and method for providing an acoustically transparent imaging display include a substrate with light sources on one side and perforations having a first visible optical reflectance, the perforations extending perpendicularly to the display surface and being disposed between the light sources. The side of the substrate opposing the light sources faces a black surface of an enclosure.

A layer having a second visible optical reflectance is disposed on the substrate on the side of the light sources. The layer has an acoustical transparency attenuation of at most −10 dB, and when in normal light conditions the difference between the visible optical reflectance of the layer and that of the perforations is lower than the difference between visible optical reflectance of the substrate and that of the perforation.

A messaging apparatus for wearable items. The messaging apparatus may comprise a light source, at least one sensor to detect are event, and a controller to control the flashing of the light source in response to the detection of the event. The controlling of the flashing of the light source may generate at least one visible element that is visible to a viewer. Further, the light source may not be adapted in the form of the at least one visible element, but rather, the controlled flashing of the light source may be in the form of the at least one visible element.

A vehicle display device and method for elevating and rotating a vehicle configured to fit in a single car parking space, while simultaneously displaying messages through a connected electronic message display. The vehicle display device has a turntable allowing for three hundred and sixty degrees of rotation of the vehicle. The electronic message display can present multiple messages that are customizable and easily modified.

Digital signage according to an embodiment of the present invention includes: a display unit; a human body sensing sensor unit; and a control unit which controls the operation of the digital signage, wherein the human body sensing sensor unit senses a motion of a human body and the distance between the human body and the digital signage, and the control unit can control so as to divide a frame buffer of content according to a predetermined set value, and to change an arbitrary pixel in a region of the divided frame buffer to black.

A content delivery system using social affine targeting may include a device that determines, based on presence information received from mobile devices, users in a vicinity of an electronic billboard. The device may further determine, based on user behavior information relating to the users, affinities of the users; and determine commonality of the affinities of the users. Still further, the device may select, based on the determined commonality of the affinities, one or more advertisements to present by the electronic billboard; and transmit the selected one or more advertisements to the electronic billboard.
