  • Method and arrangement for remote controlling a power consumption state of a network device
    Patent number: 9727116
    Abstract: The instant invention improves the control of a low-power consumption state of network devices linked to a network switch by a suitable network such as an optical network. It allows for the sleep mode also to shut down the power supplies of the components of the network device necessary for the normal data link layer network communication according to the OSI model and the higher layers of the communication protocols. In the same way, the invention prevents that a disruption of the optical network leads to a sleep mode of the network device. Further, even in a freeze state, it is possible to activate the network device and bring it in a sleep mode. For this purpose, a special communication protocol is provided.

  • Luminance boost method and system
    Patent number: 9685109
    Abstract: A system and method for increasing perceived contrast in a medical display (174) is provided. The method involves temporarily increasing luminance output of at least part of a display (174) in response to a received request for improved visualization. To compensate for the change in luminance especially while the viewer's eyes adapt to the change in luminance, the method includes continuously modifying the display parameters especially during an adaptation period to match an adaptation of the viewer's eyes. The modified parameters at any given may correlate to the degree of adaptation by the viewer's eyes to the change. After a period of time, the display (174) may be returned to its normal operating luminance and corresponding settings, which may be selected to maximize the lifetime of the display (174).

  • AD HOC ONE-TIME PAIRING OF REMOTE DEVICES USING ONLINE AUDIO FINGERPRINTING
    Publication number: 20170034160
    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.

    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.
