A sign-monitoring system includes at least one electronic sign and a controller comprising a processor and memory. The electronic sign includes a pixel array, the pixel array including a plurality of pixels. The electronic sign further includes an embedded controller coupled to the at least one electronic sign. The embedded controller develops diagnostic information for the at least one electronic sign, the diagnostic information including information related to a number of malfunctioning pixels in the plurality of pixels. The controller is communicably coupled to the embedded controller and receives at least a portion of the diagnostic information from the embedded controller. In addition, the controller assesses the at least a portion of the diagnostic information to develop health information. The assessment involves evaluating the information related to the number of malfunctioning pixels.

A self-driving vehicle with an external advertising platform, such as video display signage, designed to provide on-demand video ever-changing advertising. The audiences of such advertisements would include those individuals that were in proximity to the self-driving vehicle as it traversed a geographic area. A large fleet of such self-driving vehicles could constantly move between targeted areas, including suburban neighborhoods to reach a maximum audience, without the need of a human operator.

The vehicle includes a light-emitting part installed in the rear windshield wiper, a front camera that captures an image of the front of the own vehicle, a control unit that causes the light-emitting part to blink in conjunction with the operation of the rear windshield wiper to display the pattern, and a processing unit that acquires the pattern displayed by the blink of the light-emitting part of the preceding vehicle based on the image shot by the front camera.

Motor-vehicle body part including a lenticular sheet made of transparent molded plastic material of a given refractive index (n) higher than 1 and a given thickness (e), includes an external face forming an array of substantially spherical microlenses of a given radius of curvature (R), said microlenses being arranged with a given pitch and, an internal face of the lenticular sheet, which bears an array of three-dimensional features that are arranged with the pitch of the array of microlenses. This array of features is formed from fractions of a whole three-dimensional feature of equal dimensions, two adjacent fractions of three-dimensional features being offset in the direction in question by a given phase shift, each of these fractions of three-dimensional features magnified by a given coefficient of magnification, are juxtaposed on the internal face of the lenticular sheet with a pitch corresponding to the pitch of the microlenses.

Methods and apparatus for advertising, promoting, marketing and/or selling products and services. The inventions include a mobile vehicle and moving showroom for advertising, promotion, marketing, and sales of products and services. The products and services may be promoted for direct sale from the moving showroom, or for sale from other outlets, such as retail stores and internet sales.

A cooling and heating system for a vehicular messaging system such as a digital license plate has a micro-air pump inconspicuously mounted on a vehicle, utilized to suction cool or heated air, through an insulated air line or hose, from the occupied area of a vehicle into the enclosure of a digital license plate or vehicular messaging system, in order to maintain safe and continuous operating temperatures.

A display panel assembly includes a display panel including an array of LED (Light Emitting Diode) pixels, and includes a support assembly configured to hold the display panel near the rear window of the vehicle. In one embodiment, the support assembly for holding the display panel in the vehicle includes a first strap and a first hinge. The first hinge includes: a first flap having a first hole; a pivot; and a second flap having a second hole and a third hole. The first strap includes a fourth hole and a fifth hole located at a hinge end of the strap, and a sixth hole located at a cross beam end of the strap.

A color-changing panel that includes: (a) a transparent substrate with a bottom surface and a top surface, (b) a bottom polarization film arranged on the bottom surface of the transparent substrate, (c) a liquid crystal region comprising anisotropic liquid crystal material and configured over the top surface of the transparent substrate, and (d) an optical retardation film arranged over the liquid crystal region and above the top surface. Further, movement of the top polarization layer to a plurality of predetermined positions results in a plurality of corresponding, predetermined visible optical patterns.

Provided herein is an autonomous or semi-autonomous vehicle fleet comprising a plurality of electric autonomous vehicles for apportioned display of a media, operating autonomously and a fleet management module for coordination of the autonomous vehicle fleet. Each autonomous or semi-autonomous vehicle comprising a screen configured to display the media. Activation, deactivation, brightness modification, in combination with specific media selection enables more efficient media display.
