Abstract: A system and method to perform lane position sensing and tracking in a vehicle include using a first camera with a first field of view of a first side of the vehicle and a second camera with a second field of view on a second side of the vehicle to capture images. The method includes determining if a first lane line on a first side of the vehicle and a second lane line on the second side of the vehicle are both visible, and based on the first lane line and the second lane line being visible, determining, a position of the vehicle in a lane between the first lane line and the second lane line and determining a trajectory of the first lane line and the second lane line and of the vehicle.

Abstract: An information switch comprises a plurality of input circuits and a plurality of output circuits, the information switch being configured to communicate information units between the input circuits and the output circuits in successive transmission cycles; each input circuit being configured, in dependence upon a queue of one or more information units for transmission via that input circuit and in dependence upon hint data received in respect of a current transmission cycle, to send an information unit transmission request to one or more of the output circuits; and each output circuit being configured, in response to one or more information unit transmission requests received from respective input circuits, to select an input circuit for information unit transmission to that output circuit in a current transmission cycle and to provide hint data indicating a provisional selection, by that output circuit, of an input circuit at a next transmission cycle.

Abstract: An arbitration technique for determining mappings for a switch is described. During a given arbitration decision cycle, an arbitration mechanism maintains, until expiration, a set of mappings from a subset of the input ports to a subset of the output ports of the switch. This set of mappings was determined during an arbitration decision cycle up to K cycles preceding the given arbitration decision cycle. Because the set of mappings are maintained, it is easier for the arbitration mechanism to determine mappings from a remainder of the input ports to the remainder of the output ports without collisions.
