  • Patent number: 11620337
    Abstract: An identification and contextualization system comprising a contextualizing engine is provided. The contextualizing engine comprises various components that are operable to analyze an information item related to a user for identifying one or more individuals associated with the information item, and interrogate a graph structure for determining whether each of the one or more individuals associated with the information item is someone whom the user has met or has worked with based on edges and weights stored in the graph structure. When an individual who is associated with the information item is identified, the contextualizing engine is further operable to discover contextual information associated with the individual, and generate an information element surfacing the contextual information associated with the individual for display to the user.

  • Patent number: 11597533
    Abstract: A method and apparatus for recording flight information of aircraft, such as position, mass, or type, in order to record the position of a wake turbulence of the aircraft. Weather information can be recorded as affecting the wake turbulence. Such information can be provided into a model or algorithm to determine a path of a wake turbulence. An aircraft on a flight path to encounter the wake turbulence can determine a vortex magnitude of the wake turbulence and determine if an advisory alert needs to be provided if the vortex magnitude satisfies a predetermined threshold.

  • Patent number: 11580913
    Abstract: A voltage-programmed display system allows measurement of effects on pixels in a panel that includes both active pixels and reference pixels coupled to a supply line and a programming line. The reference pixels are controlled so that they are not subject to substantial changes due to aging and operating conditions over time. A readout circuit is coupled to the active pixels and the reference pixels for reading at least one of current, voltage or charge from the pixels when they are supplied with known input signals. The readout circuit is subject to changes due to aging and operating conditions over time, but the readout values from the reference pixels are used to adjust the readout values from the active pixels to compensate for the unwanted effects.

  • Publication number: 20220223094
    Abstract: A method and system for programming, calibrating and driving a light emitting device display, and for operating a display at a constant luminance even as some of the pixels in the display are degraded over time. The system may include extracting a time dependent parameter of a pixel for calibration. Each pixel in the display is configured to emit light when a voltage is supplied to the pixel's driving circuit, which causes a current to flow through a light emitting element. Degraded pixels are compensated by supplying their respective driving circuits with greater voltages. The display data is scaled by a compression factor less than one to reserve some voltage levels for compensating degraded pixels. As pixels become more degraded, and require additional compensation, the compression factor is decreased to reserve additional voltage levels for use in compensation.
