According to one aspect, bandwidth associated with a vehicle communication network, such as a controller area network (CAN), is allocated by assigning priorities to systems in an autonomous vehicle which use the vehicle communication network to communicate with a vehicle control unit (VCU). Systems with high priority levels may exchange data or information with a VCU at substantially all times, while systems with lower priority levels may exchange data or information with the VCU substantially only when that data or information is requested or otherwise needed. A significant percentage of the bandwidth of the network may be allocated for the exchange of data between high priority systems and a VCU, while the remaining percentage of the bandwidth may be allocated for the exchange of data between lower priority systems and the VCU when needed. As a result, the bandwidth associated with the network may be used efficiently.

According to one aspect, a method includes obtaining, at a first unit, a first signal, and storing an indication of an arrival time of the first signal in a register of the first unit. The method also includes obtaining a digital signal to be provided to a controller area network (CAN) circuit system, the CAN circuit system being included in the first unit, adding the indication to the digital signal, wherein adding the indication to the digital signal creates an updated digital signal, and providing the updated digital signal to the CAN circuit system.

Provided herein are systems, apparatuses, and methods of providing a centrifugally cast rotor assembly for an induction motor of an electric vehicle. The rotor assembly includes a rotor lamination stack with a cylindrical shape that terminates in a first end surface and a second end surface. The rotor lamination stack has multiple lamination discs, and each lamination disc has multiple rotor slots. The rotor assembly further includes copper bars disposed within the rotor slots, a first intermediary end ring disposed at the first end surface, and a second intermediary end ring disposed at the second end surface. A centrifugally cast first copper end ring that electrically and mechanically couples each of the copper bars is located proximate the first end surface, and a centrifugally cast second copper end ring that electrically and mechanically couples each of the copper bars is located proximate the second end surface.

An online system determines a polygon representing a physical location associated with a content item and indexes edges of the polygon based on their positions along an axis of a map. The index is used to retrieve edges spanning a point on the axis representing a location of a client device associated with an online system user. The online system compares the positions of the point and retrieved edges on an axis perpendicular to the axis and determines whether the user is at the physical location based on the comparison. If the user is not at the physical location, a boundary surrounding the point is compared with boundaries surrounding the indexed edges to determine whether the user is within a threshold distance of the physical location. If the user is at or within the threshold distance of the physical location, the user is determined eligible to receive the content item.

Systems, methods, and non-transitory computer-readable media can acquire a first map that represents a particular geographical region. The first map can be associated with an image map. A first vector map can be generated based on the image map with which the first map is associated. A second map that represents the particular geographical region can be acquired. The second map can be different from the first map and can be associated with a second vector map. One or more quantitative evaluations for at least one of the first map or the second map can be provided based on the first vector map and the second vector map.
