    Abstract: The invention proposes a method and an apparatus for testing a magnetic field of a coil. The method comprises applying an alternating current to the coil to generate an alternating magnetic field; measuring simultaneously the induced electromotive potential at a plurality of positions in the alternating magnetic field; and collecting and processing signals of the induced electromotive potential so as to obtain said coil's magnetic field distribution. The apparatus comprises probes positioned in said alternating magnetic field to generate the induced electromotive potential; a multi-channel data acquisition card for collecting the signals of the potential; and a processor for processing the collected signals to obtain said coil's magnetic field distribution. The method and the apparatus eliminate the interference by the magnetic field of the earth by testing the coil's alternating magnetic field to improve test accuracy and to improve the testing efficiency by multi-channel acquisition of the test signals.

    Abstract: An apparatus for detecting lock status of a spread spectrum signal, having a first accumulator, a first calculation unit, a second calculation unit, a second accumulator, a multiplier and a comparator. The first accumulator accumulates an in-phase integration result and a quadrature integration result over a time period. The first calculation unit determines a first evaluation value based on the accumulated in-phase integration result and the accumulated quadrature integration result. The second calculation unit processes the in-phase integration result and the quadrature integration result. The second accumulator accumulates the output of the second calculation unit over the time period. The multiplier determines a second evaluation value by multiplying the accumulated result from the second accumulator with a predetermined value. The comparator compares the first and second evaluation results wherein the comparison result is an indicator of the lock status.

    Abstract: An application development system, optimized for authoring multimedia titles, enables its users to create selectively reusable object containers merely by defining links among instantiated objects. Employing a technique known as Hierarchical Encapsulation, the system automatically isolates the external dependencies of the object containers created by its users, thereby facilitating reusability of object containers and the objects they contain in other container environments. Authors create two basic types of objects: Elements, which are the key actors within an application, and Modifiers, which modify an Element's characteristics. The object containers (Elements and Behaviors--i.e., Modifier containers) created by authors spawn hierarchies of objects, including the Structural Hierarchy of Elements within Elements, and the Behavioral Hierarchy, within an Element, of Behaviors (and other Modifiers) within Behaviors. Through the technique known as Hierarchical Message Broadcasting, objects automatically receive messages sent to their object container. Hierarchical Message Broadcasting may be used advantageously for sending messages between object containers that may be located remotely from each other, such as over a Local Area Network or the Internet. Even whole object containers may be transmitted and remotely recreated over the network. Furthermore, the system may be embedded within a page of the World-Wide Web.

    Abstract: A method for determining which of a plurality of data connectivity pipes will be used to transmit data for one or more applications operating on a vehicle. The method identifies which of the applications are active at a particular point in time and identifies a number of available configurations based on the number of applications that are active and the number of the data pipes that are available to transmit the data for the application. The method identifies a plurality of performance metrics for each configuration and determines an optimal performance value for each performance metric from all of the configurations. The method then determines an overall utility function for each configuration that is based on its performance metrics and the optimal performance value and selects a data pipe for each application that is active based on a maximum overall utility function from each application's available overall utility functions.
