A directional guidance system (1) includes a base (2) configured to be mounted on a surface; and an information carrier (3) mounted on the base. The base further includes a stationary portion (21), suitable for being mounted on a surface, and a movable portion (22) mounted to turn relative to the stationary portion (21) about a vertical axis of rotation (Z-Z). The system is characterized in that the information carrier (3) is mounted to turn relative to the base (2), about an axis of rotation (X-X) that slopes at an angle () lying in the range 20 and 90 relative to the vertical axis of rotation (Z-Z). The system is configured in such a manner that the turning movement of the information carrier (3) and the turning movement of the movable portion (22) are linked so that said movements conserve the orientation of said information carrier (3).

A lighting assembly includes a plurality of light emitting diodes (LEDs) and a plurality of optical elements, each proximate an associated one of the LEDs. Each optical element includes a first portion, a second portion which intersects with the first portion, a third portion extending beyond a region between the first portion and the second portion in a direction away from the associated LED, and a fourth portion positioned proximate the respective LED below the first, second and third portions. The first and second portions are shaped such that at least one surface normal to the first portion intersects with at least one surface normal to the second portion.

A display device includes a base holder having a cavity and a roller assembly. The roller assembly can include an upper cylindrical roller, a lower cylindrical roller, a framework arranged and constructed to maintain the upper cylindrical roller and the lower cylindrical roller a predetermined distance away from each other, and a conveyor belt wrapped around the upper cylindrical roller and the lower cylindrical roller. At least one or more rotating mechanisms can be attached to one or more of a left side of the upper cylindrical roller, a right side of the upper cylindrical roller, a left side of the lower cylindrical roller, or a right side of the lower cylindrical roller, where the one or more rotating mechanisms drive the lower cylinder to rotate and cause the conveyer belt to move around the upper cylinder and the lower cylinder.

A method can be used to illuminate a surface that includes a number of non-overlapping portions. The method includes simultaneously illuminating each of the portions so that the surface is substantially uniformly lit. Each portion is illuminated by a respective lighting assembly. Each lighting assembly includes a plurality of LEDs and a plurality of optical elements proximate the plurality of LEDs. For each lighting assembly, when all LEDs of the lighting assembly are operating, the entire portion of the surface is illuminated with an illumination level and a uniformity. Failure of one or more LEDs of the lighting assembly will cause the illumination level of light impinging the portion of the surface to decrease while the uniformity of light impinging the portion of the surface remains substantially the same.

Reduced cost, illuminated displays for indicating the current jackpot values are disclosed. The illuminated display comprises a front panel assembly that rests on a base assembly. The base assembly includes a one-piece housing unit that may be formed in a cost-effective manufacturing process such as through injection molding. The base assembly also holds modular electronic devices such as a LED array formed on a single printed circuit board, a power and control board for energizing the LED array to indicate the current jackpot value, as well as other modular components.

A light assembly includes a thermally conductive support structure configured for outdoor use. LEDs are attached to a circuit board and thermally coupled to a heat sink. A single transparent substrate overlies the LEDs and includes a number of optical elements. Each of the plurality of optical elements is configured to direct light from each LED in three primary directions. Each optical element includes a first portion, a second portion, and a third portion. The first, second and third portions of each optical element are configured to direct light from the associated LED in a first, second and third primary direction, respectively. The first primary direction is a lateral direction, the second primary direction is also a lateral direction and the third primary direction is approximately orthogonal to the first and second lateral directions.

An intelligent content display system includes an electronic display and one or more image sensors having a field of view. The image sensors generate image data representing a scene within the field of view. One or more conditions can be determined from the image data, such as types of objects present in the scene, including people, vehicles, among others. Such detected conditions may be used to determine what content to display on the electronic display in order to optimize the display. A model may be trained using training data to make such as a determination based on the present detected condition. The training data may include historical data which may include various performance measure values and the associated display content associated with certain types of detected objects.

A display device includes a base holder having a cavity and a roller assembly. The roller assembly can include an upper cylindrical roller, a lower cylindrical roller, a framework arranged and constructed to maintain the upper cylindrical roller and the lower cylindrical roller a predetermined distance away from each other, and a conveyor belt wrapped around the upper cylindrical roller and the lower cylindrical roller. At least one or more rotating mechanisms can be attached to one or more of a left side of the upper cylindrical roller, a right side of the upper cylindrical roller, a left side of the lower cylindrical roller, or a right side of the lower cylindrical roller, where the one or more rotating mechanisms drive the lower cylinder to rotate and cause the conveyer belt to move around the upper cylinder and the lower cylinder.

A lighting device includes a heat sink having fins on a first side and a mounting surface of a second side opposite the first side, a substrate attached to the mounting surface, a number of LEDs attached to the substrate, and a single transparent substrate with a number of optical elements, each optical element overlying an associated one of the LEDs. The device configured to direct light from the LEDs towards an area in a manner that does not create hot spots or result in dead spots on the area regardless of whether all of the LEDs of the plurality of LEDs or some of the LEDs of the plurality of LEDs are functional.
