Abstract: An onboard charging system for an electric vehicle is configured to communicate with a power supply through exchange of control signals on a power supply line by modulating a charging current being supplied to the charging system. The charging system is capable of communicating fault and battery parameter data to the power supply, as well as a requested charging current used to regulate the power supply output. The power supply may convert high voltage AC power into a controllable DC output supplied directly to the electric vehicle, thereby providing a convenient means for the vehicle to initiate charging during operations. Connection between the electric vehicle and the power supply may be effected using an extendible and retractable electrical connection, such as a mechanical pantograph.

Abstract: A system and method provide for selecting Internet media channels. Generally speaking, the selection involves choosing target channels based on user preferences. In one example embodiment, the system and method receive a user preference relating to a data item available from at least one of a plurality of media providers, augment the user preference with at least one additional preference that is related to the user preference, and select one or more media providers from the plurality of media providers, wherein the selection is based on the frequency with which the selected media provider provides the user preference or the augmenting additional preference.

Abstract: A flow control device 7A for use with apparatus 1 for discharging granular material from storage, which has an inlet adapted to receive granular material from the storage, a containment chute 7 for receiving material from the inlet and for discharging the material through a discharge opening to a conveyor system 13, includes a pivotally mounted segment gate 11 adapted to move in an arcuate manner across the discharge opening 8 of the containment chute 7 to vary the cross-sectional area of the discharge opening 8 and an actuator 12 for moving or positioning the segment gate.
