  • Patent number: 11893134
    Abstract: Devices, systems, and methods are provided for encapsulating machine learning in a clean room to generate a goal-based output. A method may include identifying, by a device operating within a clean room, an agreement between multiple parties to share data for use in machine learning to generate a goal-based output; retrieving the data; selecting the machine learning model based on a goal indicated by the agreement; generating, using the data as inputs to the selected machine learning model, a first set of probabilities indicative that a respective user may perform an action; generating, using the selected machine learning model and the first set of probabilities, a second set of probabilities indicative that a respective user may perform the action; generating the goal-based output based on the second set of probabilities; and sending the goal-based output from the clean room to a destination location.

  • Patent number: 9818347
    Abstract: This disclosure provides systems, methods and apparatus for controlling the states of a light modulator used in displays. A display apparatus includes pixel circuits coupled to the light modulators. Each pixel circuit can include an output node, a data capacitor, a charge transistor for charging the output node and a discharge transistor for selectively conducting a current between the output node and an update interconnect providing an update voltage. The display apparatus can include a controller for testing the pixel circuits to determine two or more update voltage levels, each update voltage level causing the discharge transistor to conduct current. The controller also can be configured to determine a logical high voltage level to be stored in the data capacitor based on the plurality of update voltage levels.

  • Publication number: 20120062615
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for calibrating display arrays. In one aspect, a method of calibrating a display array includes determining a particular drive response characteristic and updating a particular drive scheme voltage between updates of image data on the display array.

  • Publication number: 20070050183
    Abstract: A portable navigation device is provided that includes integrated language dictionary/translation features. The navigation device includes a user interface configured to enable an operator to enter navigation instructions as well as language dictionary/translation instructions. A receiver is provided that is configured to receive signals from global positioning system (GPS) satellites. Memory in the device stores language dictionary/translation information. A processor module receives the navigation instruction and language translation instruction, obtains obtaining navigation information based on the navigation instruction, obtains language translation information from the memory based on the language translation instruction entered by the operator. An output is provided for presenting the navigation information and the language translation information to the operator (e.g. audibly and/or visually).
