  • AUTHENTICATED INTERFACE ELEMENT INTERACTIONS
    Publication number: 20240187395
    Abstract: An access control system is provided to prevent the surreptitious granting of access to privacy related functionality on an electronic device. Software-based events to grant access to device functionality can be validated by confirming that the software event corresponds with a hardware input event. This validation prevents the spoofing of a user interface input that may be used to fraudulently grant access to specific functionality.

  • Wireless datagram transaction protocol system
    Publication number: 20050286447
    Abstract: Systems are provided for sequencing, delivery acknowledgement, and throttling of data packets over a network layer, such as UDP and SMS. To support devices with limited battery resources, the invention incorporates asymmetric retry logic and/or acknowledgements with overlapping ranges, to minimize the transmissions required for the device. The sender of a data-bearing frame does not need to wait for a frame to be acknowledged before sending the next, such that many frames can be “in flight” at once.
