  • Patent number: 11301347
    Abstract: A software update monitor is configured to receive a software update intended for a safety critical control unit. The software update monitor determines a first verification code based on the received software update from a software update component and independently receives a second verification code associated with the software update from an update server. Next, it determines if the first verification code matches the second verification code. If the two codes match, the software update monitor effects the software update at the control unit. The software update monitor is configured to write the software update into a target memory location in a memory of the control unit. The software update monitor is configured to enable switching from a previous memory location, where an older software version may be running, to the target memory location, where the new software update is written, if the first and the second verification codes match.

  • Patent number: 11172353
    Abstract: A band steering method and a system for a wireless network is disclosed. The network comprises a first and a second radio band, an access node, and a plurality of client devices having single or dual band capability. According to the method, the access node receives a probe request from one of said client devices on the first or second radio band. The probe request indicates whether the client device has single or dual band capability. Thereafter, a probe response is generated by the access node only if the probe request indicates that the client device has single band capability, or if the probe request indicates that the client device has dual band capability and the probe request is received by the access node on the second radio band. On receiving the probe response the client device can use the appropriate radio band for communications within the network.

  • Patent number: 11055986
    Abstract: In one embodiment, a match application identifies an edge corresponding to a road segment based on an observational point specifying an estimated position and an estimated heading. The match application performs search operations on a road network graph based on the estimated position to identify multiple candidate edges. For a first candidate edge, the match application computes a first quality level based on at least a distance between the estimated position and the first candidate edge and an angle between the estimated heading and a direction associated with the first candidate edge. Subsequently, the match application determines that the first quality level indicates that the first candidate edge has a higher quality than any other candidate edge. Finally, the match application transmits the first candidate edge to an application that associates content specified in relation to the estimated position with the first candidate edge.
