Abstract: In various examples, the ride quality of an autonomous vehicle is improved by selecting a lateral lane position based at least in part on measured road-condition information. In various examples, information describing the condition of a road is obtained by measuring vehicle motion and road noise using sensors on the vehicle. This information is stored in association with the lateral lane position of the vehicle to produce a profile describing expected ride quality as a function of lateral lane position. In some examples, this information is uploaded and aggregated on a remote server to produce a lateral profile of road condition using information collected by many vehicles.

Abstract: A system and method for geo-certifying delivery of items is disclosed. In some embodiments, a system tracks the intended delivery addresses of items as well as the actual delivery points. The system then determines if it has geo-verified geo-coordinates for the intended delivery points. If so, the system geo-certifies a delivery if the actual delivery point is within a geofence surrounding the intended delivery address.

Abstract: A cable tray assembly includes first and second cable tray sections each including a base and rails extending transversely from longitudinal sides of the base. At least one of the base and the rails defines a plurality of holes. A splice plate is configured to engage the first and second cable tray sections for attaching the first cable tray section to the second cable tray section. The splice plate defines a plurality of holes. At least one snap-fit connector includes a head and a plurality of resiliently deflectable arms extending from the head. The arms of the connector are configured to extend through aligned holes in the splice plate and one of the cable tray sections to secure the splice plate to said one of the cable tray sections.

Abstract: A long life live-fire target having a front, back, top, and bottom, the front including a bullet strike zone, the target constructed of a ferrous steel material. The target further includes at least one mount, the at least one mount and target formed as a single unitary structure, the at least one mount extending angularly away from the front into a mounting position, such that the at least one mount is positioned so that a bullet fired at the bullet strike zone is not likely to strike the at least one mount. The mounting position is formed when either the target is in an annealed state or the target is constructed of a soft ferrous steel. After the mounting position is formed, the target is heat treated to a hardened state. Cryogenic freezing of the target may also be performed followed by a tempering cycle.
