    Abstract: Disclosed are algorithms for provisioning content browsing and personalized advertising using hybrid collaborative filters, electronic audiovisual systems implementing such browsing and advertising algorithms, and motor vehicles with onboard audiovisual infotainment systems for provisioning content browsing. A method is disclosed for provisioning content browsing to an occupant of a motor vehicle. The method includes: aggregating vehicle-related data and user-specific data associated with the motor vehicle and the occupant; creating a database of content data received from a distributed computer network; determining, via a Recommendation Engine, multiple recommendations by applying a hybrid collaborative filter to the stored content data based on the user-specific and vehicle-related data; transmitting the recommendations via a Dialogue Engine to the occupant through an electronic audiovisual system of the motor vehicle; and receiving one or more user selections of one or more of the transmitted recommendations from the occupant through the electronic audiovisual system.

    Abstract: A positioning method includes acquiring global positioning system (GPS) position data associated with a mobile platform from a plurality of GPS satellites observable by the mobile platform. A set of wireless range measurements associated with the mobile platform and a plurality of wireless access points in communication with the mobile platform are acquired. The method further includes receiving, from a server communicatively coupled to the mobile platform over a network, wireless position data associated with the plurality of wireless access points. A corrected position of the mobile platform is determined based on the wireless position data, the wireless range measurements, and the GPS position data.

    Abstract: A method of controlling media content between a portable device and a head control unit. A first link is initiated for transmitting control signals between a control client and a control server. A second link is initiated for transmitting media content between a data server and a data client. The first link has a lower traffic volume capacity than the second link and a shorter latency for the control signals than for the media content signal over the second link. The control client generates control signals identifying a user's request and transmits the control signals to the control server using the first link. The control server provides instructions to the data server for executing the user request. The retrieved media data is transmitted from the data server to the data client using the second link. The media data is output to the user over the media output device.

    Abstract: A system for fusing two or more versions of map data together includes one or more central computers that receive road network data representing a road network for a predefined geofenced area. The central computers receive road network data that includes a discrete random curve that represents lane markings. The discrete random curve includes a plurality of state vectors that are each defined by a respective location and tangent angle. The central computers estimate the position for the state vectors of the discrete random curve based on a signed distance and the tangent angle by minimizing a spatial Kalman filter cost function and execute a Kalman smoothening function to estimate the position and the tangent angle for the state vectors that are part of the discrete random curve, where the state vectors each represent a map point of the fused map data.
