  • Publication number: 20060250510
    Abstract: In one embodiment, a configurable timing generator outputs at least one timing signal. The configurable timing generator comprises a first timing generator configurable to output the at least one timing signal so that the at least one timing signal is adaptable to a plurality of applications. In one embodiment, a configurable parameter storage unit comprising a parameter storage area configurable so as to store a plurality of parameters at least partially defining a desired plurality of waveform hierarchy elements, where the desired plurality of waveform hierarchy elements enable the definition of a waveform. In one embodiment, a method of constructing a waveform for a configurable timing generator, the method comprising acts of constructing a first pattern waveform, where the first pattern waveform comprises a first basic pulse, and constructing a first sequence waveform, where the first sequence waveform comprises a plurality of repetitions of the first pattern waveform.

  • Publication number: 20030131073
    Abstract: A schema-based contacts service for Internet access to per-user contact data, wherein access to data is based on each user's identity. The contacts service includes a schema that defines rules and a structure for each user's data, and also includes methods that provide access to the data in a defined way. The contacts schema thus corresponds to a logical document containing the data for each user. The user manipulates (e.g., reads or writes) data in the logical document by data access requests through defined methods. In one implementation, the contacts schemas are arranged as XML documents, and the services provide methods that control access to the data based on the requesting user's identification, defined role and scope for that role. In this way, data can be accessed by its owner, and shared to an extent determined by the owner.

  • Patent number: 6411311
    Abstract: A computer implemented method is described for enabling a user to transfer, via a graphical user interface, an item from one displayed window to another displayed window. Initially, a first window is displayed with an item to be moved and a second window is displayed with one or more destinations to which the item can be moved. Thereafter, the user selects the item to be moved, causing a further window to be displayed which includes one or more commands, one of which manifests a movement action. Upon selection of the movement command, the graphical interface displays a list of destinations with which the item to be moved can be associated by actuating the movement command. Thereafter, responding to a selection of one of the displayed destinations, the computer which operates the graphical view user interface associates the item being moved with the selected destination and alters the display so that at least one of the displayed windows manifests the movement action.

  • Patent number: 6311664
    Abstract: A power switch operable to change between a conductive and non-conductive state for use with an ignition circuit of an internal combustion spark-ignited engine and adapted to be disposed between the output conductor of a high voltage generator or ignition coil and an ancillary system, such as an aftermarket ignition system, anti-theft system or speed control governor circuit. The power switch receives a high voltage pulse-type signal from the engine's original equipment high voltage generator or “coil” and connects the primary power source, such as a battery, to the auxiliary system. Power is supplied to the ancillary system in synchronization with the output signal from the high voltage coil.

Power is supplied to the ancillary system in synchronization with the output signal from the high voltage coil. The power switch is particularly adapted to permit use of aftermarket ignition systems and other auxiliary circuits with original equipment ignition systems without interrupting the electrical connections or systems that rely on signals from the high voltage generator or coil of the original engine ignition system.

  • Patent number: 5803059
    Abstract: An ignition synchronization system and method of using the same are provided for the ignition systems of internal combustion engines. The system retains all of the parts of the vehicle's original ignition system. The system adds a new ignition device having a new spark energy generating coil. In addition, a spark energy signal converter is also provided. The spark energy signal converter and the new ignition device are connected in series, respectively, between the original coil and the vehicle's original elements for distributing the spark energy. The firing signal from the vehicle's electrical system triggers the original coil to generate a spark energy pulse. The spark energy signal converter absorbs the spark energy from the original coil and generates a signal indicating that the original coil pulsed. The converter, in turn, sends a firing signal to the new ignition system, which generates spark energy for the spark plug.
