Abstract: A mechanism is provided for controlling the internal air-quality of a vehicle. Responsive to determining that a speed of a vehicle fails to be above the predetermined low-speed threshold, a determination is made as to whether an internal air-quality from an internal air-quality sensor is better than the external air-quality from an external air-quality sensor. Responsive to the internal air-quality being better than the external air-quality, a ventilation control mechanism is signaled to utilize a recirculating-air mode, wherein the ventilation control mechanism either stays in an already initiated recirculation-air mode or switches to the recirculating-air mode. Responsive to the internal air-quality being worse than the external air-quality, the ventilation control mechanism is signaled to utilize a fresh-air mode, wherein the ventilation control mechanism either stays in an already initiated fresh-air mode or switches to the fresh-air mode.

Abstract: A system, method and computer program product for retrieving trajectory data from huge datasets. In the method, there is received, at a processor device, a user query including a request for displaying trajectory data at a user device. From the user query, a query type and a current map visualization scale setting (mapscale) for visualizing the trajectory data on the user device display is determined. Then, responsive to a user query type and the determined mapscale setting, a corresponding reference level is selected. Based on the selected reference level, there is accessed from a memory storage device a data set of compressed trajectory data. This compressed trajectory data set is communicated to the user device, for presentation on the user device display. In one aspect, the system and method is adaptive, enabling storage and retrieval of trajectory data according to various degrees of visualization or granularity.

Abstract: A method for evaluating fraudulent data in a Usage Based Insurance (UBI) system, includes retrieving trip data for a driver from a database. A processor on a computer determines tough context incidents in the trip data. Driving behavior of the driver during said tough context incidents is compared with driving behavior of other drivers during similar tough context incidents. The trip data is identified as potentially fraudulent if the driver's driving behavior is better by a predetermined amount compared to the other drivers' driving behavior.

Abstract: Dispatching messages in a moving object, in one aspect, may include receiving a description of a spatial area. A hierarchical tree representation of the spatial area may be generated. The hierarchical tree representation may comprise nodes, wherein a child node represents a sub-region of a region represented by a parent node of the child node. Moving features may be associated with each of the nodes, the moving features comprising whether the node is cacheable, whether the node covers an unpartitioned area, an active object list in an area covered by the node, and a latest position associated with an object in the active object list. Data from the moving object may be dispatched based on the hierarchical tree representation.

Abstract: A method and apparatus of location sequence inferences for moving objects traveling along a path. The method and apparatus primarily concerns determining the location of a moving vehicle on a roadway in a roadway network. The inputs to the system include: raw GPS tracking sequence with timestamp, trajectory of the moving object inferred by map matching, accurate speed sequence from a reliable device, e.g. OBD (On-Board Diagnostics is an automotive term referring to a vehicle's self-diagnostic and reporting capability), historical map matching results and historical locations sequence inference results. The output of the system is a sequence of more accurate location (on road segments) sequences than raw GPS locations and map matching results.

Abstract: A battery charger controller is configured to add a compensation current in the feedback control loop such that the output voltage varies with the output current to compensate charging cable voltage drop. In some embodiments, the output voltage is also proportional to a compensation resistor. Therefore, cable voltage drop compensation can be adjusted using a resistor that is external to the controller IC. The external resistor may be one of the feedback resistors connected at a voltage feedback pin. In another embodiment, the adjustable resistor is the resistor between the feedback resistors and the voltage feedback pin. In still another embodiment, the adjustable resistor is the resistor in parallel with a compensation capacitor. In embodiments of the invention, adjusting the resistance of the external compensation resistor can change the voltage drop compensation and allow the power supply to meet requirements of different charging cable applications.
