A vehicle warning sign comprises: a reflective material for at least visible light; and at least one of (i) a heating element for detection by a thermal sensor or (ii) a corner reflector for detection by a radar, the corner reflector oriented substantially in a common direction with the reflective material.

A sign comprising a substrate having a planar sign face and an opposing planar back face having peripheral side edges; a recessed portion formed within said substrate having an opening and a bottom, and side walls; a RFID tag assembly having a metal shielding sheet, said RFID tag assembly having a mounting substrate, a double-sided adhesive sheet with one side adhered to a metal shielding sheet and an opposing side adhered to said bottom of said recessed portion; a retroreflective sheeting having a double-sided pressure-sensitive adhesive sheeting for application over said RFID tag assembly to hermetically seal said RFID tag assembly within said recessed portion; a translucent vinyl backed material with primary indicia applied to said retroreflective sheeting; and a label with secondary indicia applied to said back face via label adhesive.

A safety warning sign, when not in use, is rolled and stored inside to case, and in the event of emergency, when a driver opens the trunk and then opens the case by pulling a cover with a finger while the case is attached and affixed to the edge of the trunk by means of a magnetic body of an attachment member connected to the case, the safety warning sign stored in the form of a roll inside the case is, simultaneously as the case is opened, automatically spread open by its own weight (gravity) and deployed, thus allowing the driver, even in the state of panic from an accident, to easily and rapidly install the car safety warning sign and quickly escape to safety.

A system for simultaneously producing immersive visual effects on an inside of an enclosure and passive visual effects to be viewed from the outside of the enclosure. The enclosure includes a plurality of sidewalls each having a reflective inner surface facing one other. The system includes a digital video display positioned to direct digital video imagery through the semi-reflective sidewall and into the enclosure. Light of the digital video imagery reflects off the reflective inner surfaces of plurality of sidewalls, which allow a percentage of the light to leave the enclosure, making the visual effects observable from the outside. The light will continue this cycle of reflection and transmission, creating an observable infinity effect from the outside, and an entirely enclosed visual experience from the inside.

A display device according to one or more embodiments may be provided with: a light guide plate that guides incident light and emits the light from a light exit surface; a half mirror disposed on the light-exit-surface side of the light guide plate; and a mirror disposed on the side opposite to the light exit surface of the light guide plate. The light guide plate may form an image accompanied by a change that is made in a direction from the half mirror toward the mirror in a space different from the light exit surface.

A portable, self-illuminating traffic sign having a sign face with two opposite sides. One side indicates a first traffic signal, and the other side indicates a second traffic signal. Light assemblies are attached to each side of the sign. The light assemblies emit light that may match the predominant color of one of the sides of the sign. A battery may be disposed in a pole that connects to the sign. A handlegrip allows for the sign to be held and provides a switch to allow for the lights to be selectively turned on and off. The light assemblies are disposed within collar assemblies so as to reduce, or prevent, light emitted from the light assemblies reflecting off of the sign faces.
