Abstract: A wireless interface includes: network formation circuitry configured to establish a wireless network between a primary node and a secondary node; data exchange circuitry configured to perform data exchanges between the primary node and the secondary node using secure sessions; and key refreshment circuitry configured to derive a new network key for the network based on a pre-shared key and a current network key concatenated with a session count. The new key is derived during at least one of the secure sessions.

Abstract: At least some aspects of the present disclosure provide for a method of data transmission, performed by a wireless device. In some examples, the method includes receiving a localization tone having a first value. The method further includes inserting the localization tone into a data packet at an application layer of a communication protocol stack, the localization tone preceding data of a payload of the data packet and having a last bit immediately preceding a first bit of the data of the payload. The method further includes generating a modified localization tone estimating an effect of processing on the localization tone, wherein the modified localization tone is generated and configured to have the first value after undergoing processing. The method further includes replacing the localization tone in the data packet with the modified localization tone. The method further includes transmitting the data packet.

Abstract: In an example, a method includes connecting a first BLUETOOTH device to a second BLUETOOTH device via one or more links within a link cluster. The method also includes receiving a request at the first BLUETOOTH device from the second BLUETOOTH device to change one or more link connection parameters of a link within the link cluster. The method includes, responsive to receiving the request, changing the link connection parameter of the link within the link cluster.

Abstract: A method for key refreshment in a wireless network system using a salt. The method includes receiving, from each of a plurality of secondary nodes communicably coupled to a primary node, a current session number. The current session numbers are compared to a session number at the primary node to identify a mismatch, and a salt is generated responsive to identifying the mismatch. The method further includes sending the salt to each of the plurality of secondary nodes having a current session number matching the session number at the primary node.

Abstract: In examples, a vehicular battery management system (BMS) comprises a set of battery cells and a secondary network node coupled to the set of battery cells. The secondary network node is configured to measure a parameter in the set of battery cells and generate a packet containing the parameter. The packet indicates a number of super frame slots that have elapsed from a start time of a super frame to the generation of the packet. The secondary network node is configured to wirelessly transmit the packet within the super frame to a primary network node. The primary network node is configured to wirelessly receive the packet and to determine a time at which the secondary network node generated the packet based on the indication, a time duration of each slot in the super frame, and the start time of the super frame.

Abstract: A vehicular battery management system (BMS) comprises a battery controller, a set of battery cells, a primary network node coupled to the battery controller, and a secondary network node coupled to the set of battery cells. The primary and secondary network nodes are configured to wirelessly communicate with each other using frames that share a common frame format. The frame format includes one or more bits and a status of the one or more bits indicates whether the secondary network node is to communicate with the primary network node on behalf of another secondary network node.

Abstract: A system (and method) automatically extends a scheduled recording of a live event past its scheduled end time. The system include includes a content interface to receive program content. The system also includes a user interface to permit a user to schedule a user-selected program content for recording. The user-selected program content has a scheduled start time and a scheduled end time. A program content analyzer may detect a pattern in the user-selected program content. A recording unit may record the user-selected program content and automatically extend the recording past the scheduled end time based on whether the pattern is detected.
