  • Publication number: 20240284170
    Abstract: Implementations of the present disclosure relate to detection of an untrusted configurator. In the implementations, an access point (AP) receives enrollee authentication information simulated by the network device from a network device. Then, the AP simulates an enrollee and broadcasts a configuration request including the enrollee authentication information. When a configurator responds to the configuration request, the AP identifies the configurator as an untrusted configurator, and then the AP transmits device information of the untrusted configurator to the network device. In this way, the untrusted configurator in the serving range can be detected, thereby avoiding the devices being provisioned to connect to untrusted networks.

  • Patent number: 9819478
    Abstract: In one embodiment, an integrated circuit has one or more multi-channel transmitters, each transmitter having synchronization circuitry that synchronizes different copies of a reset signal used to reset different sets of TX channel circuitry used to generate the multiple TX signals, to reduce the skew between the different TX signals. Each set of synchronization circuitry has (at least) two synchronization stages that re-time different copies of the reset signal to a selected clock signal. In one implementation, the integrated circuit has (at least) two quads, each of which can generate four different TX signals, where both quads can be configured to use the same clock signal to re-time different copies of the reset signal such that the eight different TX signals are all synchronized to one another.

  • Patent number: 8370691
    Abstract: In one embodiment, a programmable logic device (PLD) with configuration memory includes at least one configuration memory cell and soft error detection (SED) logic for checking for errors in data stored by the configuration memory. The SED logic calculates a present data value for the configuration memory for comparison with a pre-calculated data value. A fuse within the PLD is configurable in a first logic state to enable the SED logic to read from the configuration memory cell in calculating the present data value and configurable in a second logic state to prevent the SED logic from reading from the configuration memory cell in calculating the present data value. The SED logic may be tested for correct operation by writing data representing a soft error into the configuration memory cell and enabling the SED logic to read from the configuration memory cell in calculating the present data value.
