Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for enhancing liveness in a blockchain. Various aspects may include running a first consensus protocol. Aspects may also include detecting a liveness attack in the first consensus protocol. Aspects may also include suspending, when the liveness attack is detected, acceptance of new blocks in the first consensus protocol. Aspects may also include broadcasting a preferred block and identifying a highest accepted block in the set of nodes from running the first consensus protocol based on the preferred block. Aspects may also include transitioning from the first consensus protocol to the second consensus protocol and running the second consensus protocol until a consensus value or a new accepted block is decided. Aspects may also include reinstating and resuming running the first consensus protocol based on the new accepted block.

Abstract: A method for misbehaviour warnings in an intelligent transportation system (ITS) including determining at a network server that an ITS station is misbehaving. In response to determining that the ITS station is misbehaving, the network server transmits a misbehaviour warning message to the ITS station indicating that the ITS station is misbehaving. In response to transmitting the misbehaviour warning message and determining that the ITS station is continuing to misbehave, the network server includes information of the ITS station in a certificate revocation list (CRL) and transmits the CRL.

Abstract: A waveguide combiner assembly for an AR or VR display. A waveguide combiner has front and rear surfaces each substantially parallel to a waveguide plane normal to a waveguide axis. The distance between the front and rear surfaces along the waveguide axis is the thickness of the waveguide combiner. A chassis includes a support arm for supporting the waveguide combiner. A cavity is defined between front and rear walls of the support arm which are spaced along a first direction by a distance greater than the thickness of the waveguide combiner. The waveguide axis and the first direction define an offset angle between them. An edge portion of the waveguide combiner extends into the cavity. An actively adjustable mounting structure is configured to hold a respective point of the edge portion of the waveguide combiner at a selected position relative to the support arm, enabling adjustment of the offset angle.
