Abstract: Disclosed herein are a method and apparatus for automated following behind a lead vehicle. The lead vehicle navigates a path from a starting point to a destination. The lead vehicle and the following vehicle are connected via V2V communication, allowing one or more following vehicles to detect the path taken by the lead vehicle. A computerized control system on the following vehicle (a Follow-the-Leader, or FTL, system) allows the following vehicle to mimic the behavior of the lead vehicle, with the FTL system controlling steering to guide the following vehicle along the path previously navigated by the lead vehicle. In some embodiments, the lead vehicle and following vehicle may both use Global Navigation Satellite System (GNSS) position coordinates. In some embodiments, the following vehicle may also have a system of sensors to maintain a gap between the following and lead vehicles.

Abstract: Techniques and systems for providing user sentiment metrics are described that can help assess user sentiment with experiences by creating user sentiment metrics that combine telemetry data with user research data in a manner that takes a memory aspect into consideration. A user sentiment metric service can manage a user history data resource. The user history data resource can include user history information associated with a user having a user identifier. The user history information can include a plurality of events, each event having an event identifier and a timestamp. The user sentiment metric service can generate, for a unit of time, a user sentiment metric for a user using events occurring prior to and during the unit of time. The events can include events obtained from the user history information. The user sentiment metric can apply the user sentiment metric to an application.

Abstract: A steering shaft bearing assembly (100) for a vehicle having a steering shaft (102). The steering shaft bearing assembly includes a bearing (108) having a bore (112) adapted to receive the steering shaft and a support body (120) having an outer surface (124) and a passageway (126) passing through the support body. The bearing is at least partially disposed in the passageway so as to be suspended by the support body in the passageway in a predetermined position. The support body comprises a flexible material for permitting the bearing to move from the predetermined position. About 50% or more of the outer surface of the support body is free of a rigid support structure for restricting movement of the support body when coupled to the vehicle during operation.
