Abstract: Various embodiments enable user-applied annotations that arecreated and visually associated with an asset on one appliance to be shared amongst and synchronized between other appliances working together in a collaborative workspace environment. As an annotation is made, a stroke collection is defined and provided into a formatted list that represents the annotation. The formatted list is transmitted to a collaboration server which then notifies other appliances of the new annotation. When the other appliances request the formatted list, the collaborative server transmits the formatted list to the other applications so that the new annotation can be rendered on a corresponding display device.

Abstract: Cross platform shared asset techniques are described. In one or more implementations, a version of an asset is received that is configured to support consumption via a corresponding application. Another version is formed of the asset as one or more images from one or more pages of the asset. Responsive to receipt of a request from an appliance to obtain the asset for consumption as part of a shared workspace, a determination is made as to whether the appliance is to consume the asset using the application. Responsive to the determination that the asset is not to be consumed by the appliance using the corresponding application, a communication is formed for receipt by the particular appliance via a network that includes at least said image from the other version of the asset.

Abstract: Various embodiments provide a so-called snap grid that can be shared amongst various appliances in a collaborative workspace environment. A snap grid is a logical object that defines a series of cells. The cells can be generally contiguous with one another, or can be detached from one another and spread out across a workspace. In operation, a snap grid is assigned to a given workspace and serves to enable assets, such as digital content, to be fixed in predefined locations within the workspace. Snap grids are defined and rendered based on percentages of the total workspace that the snap grid occupies. These percentages can be described by metadata to permit snap grids to be shared and rendered across other appliances in the collaborative environment.

Abstract: Techniques are described to transcode and control distribution of assets as part of a shared workspace. An asset is received for distribution as part of a shared workspace implemented using a plurality of appliances communicatively coupled, one to another, via a network. One or more settings are obtained that dictate which transformations are to be applied to the asset to form the plurality of versions of the asset. The asset is transcoded into a plurality of versions of the asset. Each of the plurality of versions has a difference, one to another, in a respective one of a plurality of characteristics of the asset. Distribution is controlled of the plurality of version of the asset as part of the shared workspace to the plurality of appliances.

Abstract: Systems and techniques for scanning-beam display are provided to use local dimming on the optical energy of at least one optical beam to minimize the non-uniform image brightness across the screen. This local dimming during the beam scanning can be achieved by adjusting optical energy of at least one optical beam during the scanning based on (1) the location of the scanning optical beam and (2) the predetermined distortion information at the location.

Abstract: Techniques and optically excited light-emitting devices based on phosphors are provided to use phosphor materials which absorb excitation light to emit visible light and include a composite phosphor material including two or more different transition metal compounds that, under optical excitation of the excitation light, emit visible light at spectrally close but different spectral wavelengths or bands that spectrally overlap to produce a desired color.

Abstract: A display screen includes a filter layer, a fluorescent layer having parallel fluorescent stripes, and an attachment layer between an excitation side of the fluorescent layer and a first side of the filter layer to attach the excitation side of fluorescent layer to the filter layer while providing vertical separation therebetween. The attachment layer includes attachment regions that are separated from each other by lateral spacings such that excitation-side air gaps are formed between areas of the fluorescent layer and the filter layer that correspond to the lateral spacings. During display operation, excitation light received on a second side of the filter layer propagates through to the first side of the filter layer, and at least a portion of the excitation light that propagates from the second side of the filter layer travels through the excitation-side air gaps to excite the fluorescent stripes.

Abstract: A 2-D scanning system uses a fast-rotating raster-polygon as a single scanning component to produce straight scan lines over a 2-D image surface. An approach angle of incident light beams to the raster-polygon is selected to minimize pin-cushion distortion of scan lines introduced by polygon scanning on the image surface, and a tilt angle of the rotational axis of the raster-polygon is selected to position said polygon-scanning distortion symmetrically on the image surface. In addition, scan optics are configured to generate a predetermined amount of barrel distortion of scan lines on the image surface to compensate for pin-cushion distortion introduced by polygon scanning.

Abstract: An image is displayed on an electronic display device at a reduced power level. Power used by the display device is maintained below a predetermined maximum power level by uniformly scaling the initial optical intensity of an image to a lower optical intensity whenever displaying the image at the initial optical intensity would result in power consumption of the display device exceeding the predetermined maximum power level.

Abstract: An electronic display device provides closed-loop verification that specific content has been displayed by the display device. When desired digital image content is rendered as an image or video by the electronic display device, a confirmation signal is generated by one or more components of the display device to verify that the image content has been successfully displayed. The confirmation signal may include performance measurements of the one or more components of the display device and/or a signature output that is associated with a signature code embedded in the image content. The signature output uniquely identifies the digital image content.
