  • Patent number: 10348724
    Abstract: A system and method for sharing electronic data between participants of a phone conference, such as an online presentation, without a need to exchange passwords to link two devices together for data transfer nor go through a login procedure to access the data resource. To achieve this, the participants use a device or software application that samples the audio of the phone conversation and creates a stream of audio fingerprints. The streams of fingerprints are sent to a matching service on the internet. This matching service finds the fingerprints that correspond to the same conversation among the streams of simultaneous users. Once a match is found with a high enough confidence level, the matching service exchanges identifiers such as public IP addresses and sends those back to the fingerprinting units. When instructed by the user, the units can then proceed to setup a secure data connection.

  • Publication number: 20190191577
    Abstract: A tiled display which allows removal of display tiles in a controlled manner as well as access to the back of a display tile of the tiled display without having necessarily an opening in the display tile through which a tool to trigger a release mechanism would have to be inserted. Some of the display tiles can have at least one cylindrical element fastened to the display tile by an intermediary of a fastener positioned at one end of the cylindrical element. The cylindrical element is fixed to such tiles with the fastener. An actuator is provided to pull in the display tile to fit within the plane of the tiled display by activating a non-contact sensor with a dedicated non-contact device in a vicinity of the display tile until the tile slides in. The non-contact device emits a control signal received by the non-contact sensor.

  • Publication number: 20190132367
    Abstract: A method and system for conducting meetings, e.g. making it easy for the user to connect his device to the meeting or come to a common shared view of the meeting content. In the method and system, all devices participating in the meeting are located within one physical meeting room. Alternatively, at least some devices are located outside the meeting room. In principle there is no meeting room necessary, but all devices can be distributed anywhere in a region or in the world, and after connection, the meeting content is shared to all physical meeting rooms and remote devices of the system.

    Abstract: A light projection system for generating an image with three primary colors, each primary color being respectively defined by a first, second and third wavebands. The system includes a first blue laser source emitting a first beam in a fourth waveband, the first blue laser source having a first laser driver, a second blue laser source emitting a second beam having a central wavelength and a fifth waveband, the second blue laser source having a second laser driver, a substrate having a wavelength conversion element for emitting light at a plurality of wavelengths after absorption of a light beam at an excitation wavelength within a fifth waveband of the second blue laser source and a beam combiner for combining the combined first beam and the converted beam, which combination results in a white beam. Dichroic losses can be reduced by using a green phosphor together with red laser assistance.

  • Publication number: 20190011749
    Abstract: A display tile having a frame whose compliance is increased in a well determined region to accommodate the different thermal expansions of the frame and one or more substrates to which the frame is fastened. The display tile has also regions of increased compliance that will deform to allow different parts of the frame to be brought into contact and glued to the lateral sides of two superimposed substrates when at least one lateral side of one of the substrates is not coplanar with the corresponding lateral side of the other substrate.

  • Patent number: 10067727
    Abstract: The present invention relates to methods or system for the measurement of differential latency between displays located at endpoints of network, displays being driven by one or more rendering machines and having means for refreshing the images on different displays at the same point in time as well as means adapted so that the content of each displayed image can only change after the completion of previous displayed frame. For example the displays can be frame locked and have double buffered swap locked memory operation. The method or system is adapted to stream test images over the network to the displays of the different endpoints. The test images are displayed on the displays. The displayed images at the different endpoints with an image recording device such as a camera. Optionally the delays can be compensated, e.g. by delaying the streams with lower latency at the level of the frame buffer (FIFO) before or after decoding.

  • Patent number: 10056014
    Abstract: A positioning device and a fastening device to fix the relative position of two or more adjacent tiles on a tiled display and to provide alignment. Fixing the relative position of two adjacent display tiles will facilitate the alignment of tiles in tiled displays where the seam between tiles will be as regular as possible, thereby avoiding the introduction of misalignments and their associated visual artefacts. The positioning device allows linkage of it to at least two tiles of a tiled display. The display tiles are often rectangular in shape and the positioning device is then located at a corner of the tile. The positioning device can also be attached to a support structure to make a tiled display.
