Abstract: Implementations described herein generally relate to scanning beam display systems and more specifically, to systems and methods for improved image alignment of such scanning beam display systems. The method comprises providing a display system comprising a display screen having a plurality of display screen region each with a corresponding light engine module having a servo laser beam and an excitation laser beam, scanning the servo laser beam of a light engine module in an outer scanning region outside of the light engine module's corresponding display screen region, detecting servo laser beam feedback light to measure an alignment error of the light engine module relative to the light engine module's corresponding display screen region, and adjusting alignment of the excitation laser beam based on the measured alignment error.

Abstract: Large format display systems are described that are reconfigurable between an open configuration designed for performing maintenance on the system and a closed configuration designed for normal operations of the display system. In the closed configuration, the display screen is intentionally subjected to a substantial amount of tensile force to advantageously stabilize the display screen. That substantial tensile force is generated by a sturdy stationary frame that the display screen is anchored against in the closed configuration. When the display system is reconfigured to the open configuration, the display system is no longer anchored against the stationary frame. The process of reconfiguring the display system from the closed configuration to the open configuration includes relieving most of the tensile force applied to the display screen using adjustable tensioning mechanisms of the display systems.

Abstract: Various embodiments provide confidentiality-based file hosting by automatically directing assets in a shared workspace to appropriate storage locations. The storage location can be determined by comparing a security level that is associated with an asset to security levels of multiple possible storage locations. If a security level of the asset is changed in the shared workspace, the asset is automatically directed to an appropriate storage location based on the changed security level. This can include directing the asset to either a more secure or a less secure storage location.

Abstract: Techniques are described to support undo and redo operations in connection with a digital ink canvas on an appliance that can take part in a collaboration amongst multiple appliances that can share content. The digital ink canvas is a digital area that accepts inputs from a user and renders a digital stroke. The described techniques make use of a navigable history palette which includes individual history entries that each provide a visual representation of a state of the digital ink canvas at some point during the collaboration. The history palette provides a navigable user interface instrumentality which permits panning through the history palette to enable user to select a particular visual representation. The digital ink canvas is then returned to the state associated with the selected visual representation. The selected visual representation can be provided across the appliances participating in the virtual collaboration.

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 bandwidth management module on each of multiple appliances in a collaboration environment ensures that the sources, i.e. the appliances that share a common network connection, automatically share the network bandwidth without having to be aware of each other. This is done by having them compete for the available bandwidth in a self-balancing way, such that the stream with the lower bitrate will automatically consume more when extra bandwidth is available, and it will give up less when there is not enough bandwidth.

Abstract: A scanning beam display system includes an optical module, an image control module, and a display screen on which optical beams are scanned. The optical module includes a vertical adjuster placed in the optical paths of the beams to control and adjust positions of the optical beams along a generally vertical direction on the display screen, and a control unit configured to receive control instructions for the vertical adjuster and to control the vertical adjuster to be at one of a predetermined number of orientations to place the scanning optical beams at a corresponding distinct position on the display screen. The control unit is further configured to apply an adjustment offset to each orientation of the vertical adjuster such that each immediately vertically adjacent pair of beam footprints projected on the display screen resulting from the plurality of positions have a vertical overlap that is larger than a first threshold.

Abstract: A multi-layer display screen capable of being tiled without a visible gap between tiled screens and methods of using said device are described herein. In one embodiment, a system includes a light generator configured to produce light and a multi-layer screen with a plurality of layers. The multi-layer screen can be configured to permit the light from the light generator to propagate therethrough. The plurality of layers can include an opaque region layer having a plurality of opaque regions and a first layer comprising one or more abutted layers disposed within a common plane, the abutted layers spaced apart by a gap, wherein the gap is coincident with the opaque region.

Abstract: A client application coupled to a display generates a shared workspace that includes a content stream derived from a local user device a well as another content stream derived from a remote device. The client application is configured to detect when a user device is coupled locally, and to receive a content stream from that device. The client application determines when the other content stream is available, and then accesses that content stream via a streaming infrastructure. The client application then generates the shared workspace by rendering the two content streams to a display.

Abstract: The present disclosure generally relates to a LPD system having a plurality of detectors for detecting light reflected from the back surface of the screen. The detectors are positioned to detect light from one or more portions of the screen that are not directly in front of the detector.

Abstract: Various embodiments provide a context-based proactive search that can automatically, in a seamless manner, display or otherwise make available content associated with a previous visit of a current asset. Various embodiments utilize a depository to save information associated with content that has been saved by a user or content in which the user has an implied interest. When the user returns to a particular asset, the depository is automatically searched for content associated with the particular asset that has been saved. A user interface instrumentality is presented and automatically displays the saved content, or indicia of the saved content—termed a “reminder”—from the previous visit. In this manner, the user does not have to physically search for saved content from a previously-visited asset. Rather, the saved content or indicia thereof is automatically presented in a user interface instrumentality that enables the user to select the reminder to quickly and conveniently retrieve saved content.

Abstract: A display system includes a display screen, a plurality of subsystems, and a control system. The plurality of subsystems each generate an excitation beam that carries image information and a servo beam. For each subsystem, a servo feedback detector receives feedback light of the servo beam, detects the servo feedback mark, and produces a monitor signal. For each subsystem, a control unit is operable to adjust optical energies carried by the excitation beam using a scaling factor. Two adjacent subsystems of the plurality of subsystems are configured such that in operation the areas scanned by the excitation beams of the two subsystems overlap in an overlap region. The control system is configured to determine a range of the overlap region based on the monitor signals from the servo feedback detectors of the adjacent subsystems, and to determine the scaling factors for the excitation beams for the overlap region.

Abstract: Knowledge automation techniques may include selecting a knowledge element from a knowledge corpus of an enterprise for extraction of n-grams, and deriving a term vector comprising terms in the knowledge element. Based at least on a frequency of occurrence of each term in the knowledge element, key terms are identified in the term vector. Thereafter, the identified key terms are used to extract one or more n-grams from the knowledge element. Each of the extracted n-grams is scored as a function of at least a frequency of occurrence of each of the n-grams across the knowledge corpus of the enterprise, and based on the scoring, one or more of the n-grams is added to a collective term and phrase index.

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: Various embodiments enable one or more appliances to participate in a shared workspace. The shared workspace can include a single appliance, multiple appliances, a single meeting room, multiple meeting rooms, or any combination thereof. The state of various meeting participants can be identified and one or more rules can be applied to the participants' state to provide an outcome. An “outcome” can be thought of as an action that is to be performed responsive to the identified state. An asset interaction control feature can be selected based on the outcome. The asset interaction control feature controls, in some manner, a participant's interaction with one or more assets that are part of the shared workspace. The asset interaction control feature is then applied to at least one of the assets.
