A safety sign device is for a vehicle. The safety sign device may include a hinge being coupled a side of the vehicle, and an arm. The arm may include an elongate base, an electric motor coupled to the elongate base, an elongate housing coupled to the elongate base, and visual indicators carried by the elongate housing. The safety sign device may also include a sign coupled to the arm and being parallel to the arm. The hinge may include a pin, and a link assembly coupled between the pin and the electric motor and being rotatable about the pin. The electric motor may be configured to extend and retract the arm between a retracted position and an extended position.

A signage system (10) including one or more visual display devices (11), each mounted for display behind the windshield (15) of one or more parked and ignition-off vehicles (16). Each sign (11) has a visual display surface (12) that is capable of forming an illuminated graphic display (13) on the visual display surface (12). The visual display surface (12) would be visible to observers in front of the vehicle (16). The system (10) includes wireless communication hardware (60) that allows the visual display (11) to be programmed by a remote programming device (41). Each of the display devices (11) can be programmed to have a separate message and each message would scroll from left to right across the display surface (12) in a time coordinated manner so that the message appears to scroll consistently from left to right across the visual field of the plurality of display surfaces (12).

A street sign assembly is fabricated from a composite material having at least one panel for displaying indicia such as street names. Electrical conductors are embedded into the panel to permit attachment and electrical coupling of an integrated power supply module, lights and other electrical devices thereto. The integrated power supply module includes a solar panel and battery in a single weatherproof enclosure that is attachable to the panel. The battery is recharged by the solar panel and power is provided from the module through electrical leads that contact the embedded electrical conductors in the panel.

A lighted display assembly for an appliance includes interchangeable display screens. Multiple light sources flash, turn on and turn off to indicate a status of the appliance by illuminating a selected one of the display screens. A display grid extends continuously between the light sources and the selected display screen and defines light passages that are each uniquely associated with one or more corresponding light sources. Light emitted by each light source is confined to a discrete area of the display screen by the corresponding light passage. The discrete areas of the interchangeable display screens may include any of a variety of markings, for example, markings in a different language. The assemblies may be tailored to the needs of a particular customer by selecting an appropriate display screen.

The invention relates to an apparatus for displaying information on a vehicle. The apparatus comprises a display and a plate comprising a controller, a sensor and a communicator configured to communicate with an external server, wherein the controller is configured to control the apparatus such that sensor data from the sensor are sent to the external server and information received from the external server is shown on the display. A casing comprising a front wall includes the display, a back wall configured to be attached to the vehicle, and a frame, wherein the plate is arranged within the casing, wherein the frame comprises profile elements forming sidewalls of the casing and corner elements and wherein a respective corner element is detachably connected to two respective profile elements. This allows for a high adaptability of the apparatus.

A street sign authentication arrangement for a motor vehicle includes an RFID tag reader for reading information encrypted on a street sign encountered by the motor vehicle. An electronic processor is communicatively coupled to the RFID tag reader, and verifies, based on the information read from the street sign, that the information was encrypted by an authorized entity. The processor controls movement of the motor vehicle based on the information read from the street sign if the processor is able to verify that the information was encrypted by the authorized entity. The processor refrains from controlling movement of the motor vehicle based on the information read from the street sign if the processor is not able to verify that the information was encrypted by the authorized entity.

A digital license plate comprising includes a display system capable of showing a first image and a power supply rail connected to the display system. A display controller is provided with a data connection to the display system and arranged to measure at least one of power consumption and impedance of the power supply rail. The display controller is further configured to prevent sending a second image to the display system if display failure is indicated by measured power consumption or impedance as being below a defined threshold.

An arrangement in a traffic sign for replacing a plate part (4) included therein, whereby the traffic sign comprises a plurality of mutually differing plate parts (4a, 4b) of which one at a time may be switched visible and directed on a traffic route. A first body part (1) of the traffic sign, most suitably a vertical post is fixedly installed and has, adapted as an extension by a bearing (11);(12), a second body part (10) which is turnable by means of a power device (7), such as an electric motor, and to said second body part (10) there are connected different plate parts (4a, 4b) directed in different directions, whereby the desired plate part of said plate parts is turnable in the direction of the traffic route by means of said power device, and that the traffic sign includes one or more cover parts (6) that cover those plate parts (4a) or (4b) that are not meant to control traffic.

The present invention relates generally to the field of campfires and fireplaces. More specifically, the present invention relates to a fire sign device primarily comprised of at least one stand and at least one sign. The stand can be placed within a campfire or a fireplace via an attachment mechanism that includes, but is not limited to: a clamp, a stake, a stand, etc., which may further be repositionable on the stand and adjustable. The sign further attaches to the stand and may be comprised of at least one indicia that is made from a heat-resistant thermochromic paint that becomes visible when heated. In a differing embodiment, the sign is shaped like the indicia itself. One embodiment of the device includes at least one LED within the indicia that illuminates when a temperature sensor of the device detects a temperature above a threshold value.

A digital license plate comprising includes a display system capable of showing a first image and a power supply rail connected to the display system. A display controller is provided with a data connection to the display system and arranged to measure at least one of power consumption and impedance of the power supply rail. The display controller is further configured to prevent sending a second image to the display system if display failure is indicated by measured power consumption or impedance as being below a defined threshold.
