A system and method for determining and displaying an overall efficiency value of a vehicle. The vehicle may include an engine and an electric machine that operates to provide torque to propel the vehicle. In addition, the vehicle may have an electric power source that provides electric power to the electric machine. A controller may determine and transmit the overall efficiency value so that the information display displays the number of efficiency indicators. Also, the number of efficiency indicators displayed may be based on the overall efficiency value.

An Internet-scale file sharing system includes a client-side file sharing application that allows file-sharing users to identify files to share and transmit metadata corresponding to those files to a metadata repository. A server-side application operating on the metadata repository tracks metadata received from associated file-sharing users, as well as metadata from other affiliated metadata repositories. Each metadata repository acts as a search engine for any querying users and can provide search results based on locally stored metadata alone. Each metadata repository may additionally choose to locally-store popular files from an associated file-sharing user so as to alleviate transmission burdens on that file-sharing user. Associated metadata repositories each periodically synchronize their stored metadata so that all metadata repositories may generate similar search results. In such manner, file-sharing queries need only be performed by the metadata repository receiving the query, and not by all associated metadata repositories.

摘要:
There is described a sensor comprising an excitation winding, a signal generator operable to generate an excitation signal and arranged to apply the generated excitation signal to the excitation winding, a sensor winding electromagnetically coupled to the excitation winding and a signal processor operable to process a periodic electric signal generated in the sensor winding when the excitation signal is applied to the excitation winding by the signal generator to determine a value of a sensed parameter. The excitation signal comprises a periodic carrier signal having a first frequency modulated by a periodic modulation signal having a second frequency, the first frequency being greater than the second frequency. In this way, the sensor is well suited to using digital processing techniques both to generate the excitation signal and to process the signal induced in the sensor windings. In an embodiment, the sensor is used to detect the relative position of two members. In other embodiments, the sensor is used to detect environmental factors such as temperature and humidity.
