  • Patent number: 10303458
    Abstract: Systems, methods, and computer-readable storage media for multi-platform installers. In some embodiments, a computing system can launch a software package configured to perform a software installation at the computing system. The software package can then detect an underlying computing environment associated with the computing system, the underlying computing environment including a type of system, software characteristics, and/or hardware characteristics. Based on the detected underlying computing environment, the software package can select settings for a configuration update on the computing system. The settings can define network configuration parameters, system firmware parameters, drive configuration parameters, system boot drive configuration parameters, etc. Based on the settings, the software package can execute the configuration update on the computing system, and install a software application on the computing system, based on the configuration update.

  • Patent number: 9785217
    Abstract: In a method of operating a touch screen, an object interaction is detected with the touch screen while in a first doze mode. It is determined if a detected object interaction with the touch screen is a valid input object interaction with the touch screen. In response to determining the object interaction is a valid input object interaction, the touch screen is transitioned from the first doze mode to a gesture recognition mode. The touch screen is transitioned from the gesture recognition mode to an active mode in response to a determination of a valid gesture interaction with the touch screen by the input object.
