A system includes a view screen with polarized output. The view screen may include a projected view screen or writing-surface view screen. A window capable of blocking the polarized output at least in part cloaks the view screen to frustrate viewing of the view screen through the window. In some cases, the window includes an array of panels capable of blocking multiple polarizations. The array may disrupt multiple different polarized view screen outputs while maintaining transparency to unpolarized light. In some cases, the window capable of blocking polarized output may be paired with view screen cover that converts view screen output in an unblocked polarization to one of the one or more polarizations blocked by the window.

Building blocks for making structures comprising a number of translucent inflatable blocks, wherein each translucent inflatable block has six identical sides having an outer surface, an inner surface, and four vertices; a magnetic connection element configured to connected at least two inflatable blocks of the number of translucent blocks, wherein the magnetic connection element is located on the inner surface of each of the six identical sides, wherein the magnetic connection element includes four corners, wherein the four corners are equidistant to the four vertices; a proximity switch in communication with a lighting element located on the inner surface of each of the six identical sides, wherein the lighting element is configured to emit colored light when the proximity switch is activated, wherein the proximity switch is activated when the inflatable blocks are connected via their respective magnetic connection elements; and at least one valve for inflating or deflating the inflatable blocks.

A fluorescent blackboard comprises a housing, a circuit hoard fixed on the housing by screws, a display screen fixed by the circuit board, and a panel attached and fixed on the housing by the adhesive tape. The fluorescence blackboard is configured with a fixed device that limits and fixes the panel. The present disclosure uses that the fluorescent blackboard 1 configured with the fixed device that limits and fixes the panel, which makes the panel be firmly limited and fixed on the housing, which avoids the panel from coming lose. When the panel is squeezed, the fixed device can protect the panel, which avoids damage to the panel.

A multifunctional illuminated lighting pad is an apparatus that enables a user to write with one hand, rather than requiring a hand to hold a clipboard or writing surface and another hand to write down information. The apparatus provides a mechanism by which to secure to a user, thus preventing difficulty or danger resulting from a loose clipboard. An illumination source provides ample light, allowing the user to read and write in otherwise poorly-lit areas. A portion of the opaque backing may be secured to a user's pocket and molded to the rough curvature of a leg. An exposed portion of a backing surface holds a writing surface, an LED, and a clip. A thumb-pull cut allows the user to insert or remove a reference sheet from between the plexiglass front plate and the backing, thus allowing the user to refer to information behind the plexiglass front plate while writing.

A lightboard system providing the multiple advantages required by presenters to audiences. Wheels support and render mobile a base. Supported by the base, a frame defines an opening and includes pairs of vertical struts and corresponding vertical tubes, the tubes sliding along the struts in a telescoping movement to raise and lower the frame height. A clear screen is fixed within the opening; the height of the screen is adjusted as the frame telescopes. The screen has a front face displaying content from presenters and an opposing rear face, and induces paths for and scattering of light to highlight the content. A dimmable light source is embedded in the frame and illuminates the screen. Attached to a telescoping mount on the frame, a video camera is directed toward the rear face, streams or records the content to create images, and automatically flips the images for viewing by audiences.

A resource tracking system for monitoring the status of multiple resources, displaying the status of those resources, and mirroring the status information to multiple displays for remote users. The resource tracking system comprises a resource tracking board and a server. The board comprises a re-writable surface with a plurality of arrayed buttons and lights, and a network interface operably coupled to the buttons and lights. The lights emit at least three colorsgreen when the associated resource is available, yellow when the resource is reserved, and red when the resource is in use. The server is configured to generate interactive displays enabling remote users to observe and reserve available resources. The interactive displays feature a representation of at least one of the buttons and lights on the board. The server causes any status change of a resource on the board to be reflected on the interactive displays, and vice-versa.

A plurality of modular tiles can be connected to form a writing surface. The modular tiles are shaped to enable multiple tiles to be connected to form a continuous surface (e.g., hexagonal, rectangular, etc.). Each modular tile has a writing element and a friction element opposite the writing surface to prevent the modular tile form slipping when placed on a horizontal surface. The modular tiles may also have a coupling mechanism, such as magnets with appropriate polarization, allowing the modular tiles to be coupled to one another to form a large surface and then be detached for simpler storage of the modular tiles. The modular tiles may further include lights, displays, or additional electronics to allow a connected computing device to display on the writing surface.
