A method of updating an electrophoretic display that makes use of an electrophoretic display capable of receiving and displaying a transmitted digital photograph, a marker and a digital camera capable of transmitting digital images to a destination, the display including a transparent cover that can be marked on by the marker. First, an image is displayed on the electrophoretic display, and the marker is used to mark the cover, thereby forming markings. Then a digital photograph of the display is taken with the digital camera. Finally, the photograph is transmitted to the electrophoretic display and displayed on the electrophoretic display, thereby displaying both the image and the markings.

A display assembly, having a base comprised of polymeric material, and having a front wall of at least one hundred square centimeters in area, and a rearward-extending base peripheral wall of at least 0.5 cm height. The front wall has raised regions and recessed regions that extend at least as far back as the peripheral wall at its furthest rearmost extent, so that when the base is placed against a flat surface the back of the recessed regions touches the flat surface. A polymeric cover is adapted to tension fit to the base, the polymeric cover including a generally transparent front wall. Translucent display media interposed between the base and the cover and a set of energy efficient lighting devices disposed in the recessed regions.

A display apparatus is provided. The display apparatus includes a display, a sensor to sense a touch on the display, a communicator, a storage configured to store matching information on which the display apparatus and at least one input source each match different touch types and a processor configured to, if it is identified that a touch type of the touch sensed by the sensor corresponds to a specific external input source based on the stored matching information, control the communicator to transmit information corresponding to the sensed touch to the specific external input source.

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.

A new design for a dry-erase board allows for writing on a clear top surface or a second surface under the clear top surface. The dry-erase board includes an insert positioned between the clear top surface and a second surface, the insert being protected by the clear top surface.

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.

An image projector device includes a projection optical unit through which an image is projected and displayed, a recognition unit that recognizes a user's action related to processing of the image, and a control unit that generates and/or edits a drawing image based on the user's action recognized by the recognition unit and projects and displays the drawing image being generated and/or edited as a projected, displayed image through the projection optical unit.

A resource tracking system for monitoring the status of multiple resources, displaying the status of those resources to medical personnel, and mirroring the status information to multiple displays for remote users is disclosed. In the preferred embodiment, the tracking system is used to track the availability of beds in a hospital or treatment facility. The resource tracking system comprises a resource tracking board and a server. The board comprises a re-writable surface with a plurality of buttons and lights arrayed in one or more columns; and, a network interface operably coupled to the plurality of buttons and plurality of lights. The lights are configured to emit at least three colors including green 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 display features a representation of at least one of the plurality of buttons and lights on the physical board. The server causes any change in status of a resource on the physical board in the hospital or treatment facility to be reflected on the interactive displays. The server also causes any change in status of a resource on an interactive display to be reflected on the physical board in the hospital or treatment facility.
