Abstract: An electronic device is described. The electronic device includes a master integrated circuit (IC) that includes a master finite state machine (FSM). The electronic device also includes a slave IC that includes a synchronization module and a slave FSM. The electronic device further includes a control interface coupling the master IC to the slave IC. The control interface is implemented via a single wire. The master FSM communicates its states or state transitions to the synchronization module via the control interface. The synchronization module decodes the master FSM's states or state transitions and uses the decoded states or state transitions to step the slave FSM in real time such that states or state transitions in the slave FSM mirror the states or state transitions in the master FSM.

Abstract: In one embodiment, a method comprising sampling by a first sampling unit a first signal received via a first antenna; and sampling by a second sampling unit a second signal received via a second antenna, the sampling of the second signal commencing in synchronization with the sampling of the first signal by the first sampling unit based on an accumulated value, the first and second signal sharing common information.

Abstract: According to various embodiments a secure alternative to wired or numeric association models currently required by, for example, Wireless USB, can use biometric data to generate a unique security key that can be used to help secure a connection between a multiple devices. According to one embodiment a fingerprint reader can be used on a wireless USB host and a wireless USB device to generate a unique key that can be used to establish an initial link between them. The host and device can then generate a connection key that can be used for all future communication between the host and the device. Once the connection context has been transferred between the host and the device the fingerprint key can be discarded. According to another embodiment of the invention, a key generated using biometric data can also be used as a connection key, rather than generating an additional key. In this embodiment the biometric key would not be discarded.
