The present invention relates to an illuminated frame system for framing a display unit, such as a screen and the like, comprising a frame on which lighting means, preferably in the form of LEDs, are arranged. An illuminated frame system of this kind may advantageously be used in gaming devices which have at least one screen.

This invention is intended to strengthen play transmission between players and coaches before, and during plays. The wristband is an elastic, or adjustable wristband with a clear plastic window and LED strips or LED matrix that lights the Light Emitting Diode (LED) next to a desired play. The wristband is wirelessly linked to either a radio frequency panel, bluetooth device, or infrared controller. The wristband LED's are wired to a microcontroller, Bluetooth controller (or RF transceiver, or Infrared controller), and a battery power source. The LED's are displayed through the clear plastic window and the plays are slid over the top of the LED's. The micro controller, battery and wireless controller are contained in a velcro-enclosed, low-profile enclosure opposite the clear plastic window.

A seat accessory (10) comprises an elongate, generally planar member which is deformable in order to secure the ends to the opposite edges of a seat back. The elongate, generally planar member comprises two generally planar deformable elongate portions (16a, 16b) which are separably joined to one other. At least one of the portions (16a, 16b), when separated, comprises a wearable item which is deformable to wrap around a body portion of a wearer.

The present invention is applicable to the field of an LED display screen, and provides a method and device for separating a rebroadeasted video from a live display video, the method includes: feeding the rebroadcasted video and the live display video of the LED display screen into a video processor by two paths; completing an aliasing of two paths of the videos through the video processor, sending the aliased video to a LED display control system; controlling by the LED display control system a video ratio of the two paths of the videos, utilizing a high-speed camera to synchronously capture the rebroadcasted video according to the video ratio; receiving by the LED display control system the rebroadcasted video synchronously captured by the high-speed camera; and transforming by the LED display control system through image processing the rebroadcasted video into a video which is to be rebroadcasted to different countries. The present invention has the following two technical effects: on one hand, the present invention realizes the separation of the rebroadcasted video of the LED display screen from the live display video thereof around a stadium and meets different needs of different countries; on the other hand, the present invention is compatible with the LED video display technology in the prior art and can achieve a multi-purpose screen.

A lighting apparatus includes a first light source, a second light source, a first light guide plate, a second light guide plate and a driver. The first light source emits a first light. The second light source emits a second light. The first light guide plate receives the first light from a first lateral wall and guides the first light to escape via a first surface of the first light guide plate. The second light guide plate receives the second light and guides the second light to escape via a second surface of the second light guide plate. The second surface has an image pattern. The image pattern is rendered by placing multiple first light escaping dots on the second surface. The multiple first light escaping dots are divided into multiple sets for rendering multiple visual objects by arranging area intensities of the first light escaping dots.

A lighting system for a hat includes a front housing containing lighting elements that mates with a back plate positioned on the inside of the hat. Driver circuitry controls operation of the LEDs for various lighting modes, and a cover for the front housing is translucent and designed in the shape of a recognizable logo or other design. Electric power comes from a battery located on the back plate, and is provided through the hate using prongs or projections that pass through the hat, from the back plate to a circuit connector in the front housing. The circuit connector is electrically coupled to circuitry on a circuit board in the front housing.

A billboard which is formed as a dasher board (600) and adapted for use in a video content replacement system (400) is described. The dasher board (600) comprises at least one non-visible radiation source (604) arranged to emit non-visible radiation toward a light guide plate (602). The light guide plate (602) is arranged to distribute the non-visible radiation over the light guide plate (602) and radiate the non-visible radiation away from the dasher board (600). An area of the light guide plate (602) over which non-visible light is distributed from is correlated to an area of the dasher board (600) which is to be replaced in the video content replacement system (400). There is also described is a billboard (700) similarly adapted for use in a video content replacement system (400) and which comprises an electronic display, as well as a method of retrofitting an existing billboard (10) ready for use in a video content replacement system (400).

A light box includes a light passing cover printed with an image. The image is being logically divided into two-dimension blocks. The light box includes multiple light tubes. Each light tube includes a tubular housing, an elongated LED bar, and a controller. The elongated LED bar is being enclosed by the tubular housing. The elongated LED bar has multiple LED modules divided into multiple LED sections. The multiple light tubes is being disposed behind the image of the light passing cover. The multiple LED sections of multiple light tubes is being corresponding to the two-dimension blocks of the image respectively. The controller controls the multiple LED sections separately according to a stored script. The stored script indicate a timing sequence for controlling the multiple LED sections for illuminating the two-dimension blocks of the image according to the stored script.

An electronic display and method for memorizing a theme are disclosed. A theme is exhibited via a picture and a plurality of phrases associated with the theme. The phrases are intermittently highlighted individually over the picture. Each word of each phrase is designated a fixed location relative to the picture, each phrase being scattered over the picture and a phrase is interspersed among other phrases.

Light emitting diode (LED) light tubes having rotatable end cap assemblies are described. The LED light tubes include a hollow tube and a circuit board with LED chips thereon. The end cap assemblies are provided on either end of the tube. Each end cap assembly includes a socket cap, a plug having a plug body and at least one connector, and an end cap body, one end of which engages one of the ends of the hollow tube. A cam locking mount that is positioned within the plug body and on the opposite side has projections to be positioned in the bore of the end cap body. A rotation cam is seated in the cam locking mount and provides for controlled rotation of the LED tube relative to the end caps. Methods of installing the LED light tubes in new installations and retrofit installations and for use in sign assemblies are also described.
