Abstract: A method and system for cleaning a brake booster aspirator shut-off valve are provided. The shut-off valve is operable to selectively permit flow of intake air through an aspirator; the aspirator bypasses a throttle of an engine and provides a vacuum source for a brake booster. The method comprises determining whether the shut-off valve may require cleaning, opening the shut-off valve so as to permit a flow of air through the shut-off valve and clean the shut-off valve and adjusting the throttle position of the engine to compensate for the additional flow of intake air through the aspirator.

Abstract: A method and system of cleaning a turbocharger bypass control valve, the control valve being operable to vary the position of a bypass valve and thereby vary the amount of flow bypass across a turbine and/or compressor of a turbocharger for an engine. The method comprises: determining whether the control valve may require cleaning; adjusting the duty cycle of the shuttle so as to increase a flow of fluid through the control valve and clean the control valve; and adjusting a throttle position of the engine and thus the engine torque output to compensate for the adjustment in the amount of boost provided by the turbocharger.

Abstract: An ambient effects system and method of operation is described in which regions (30, 38) of a game or movie screen (10) are analyzed (32, 40). The result of the analysis is then processed using logical, heuristic, or a combination of both techniques to determine a content related event. An ambient effects script (34, 36, 48) is then selected (if pre-authored) or generated (if not pre-authored) on the basis of the determination, and provided to the system to render appropriate ambient effects throughout the users environment. Hence, immersive, ambient effects are enabled for media or game content created independently of, and without, the ambient effects system in mind.

Abstract: A system and method is described in which a multimedia story is rendered to a consumer in dependence on features extracted from an audio signal representing for example a musical selection of the consumer. Features such as key changes and tempo of the music selection are related to dramatic parameters defined by and associated with story arcs, narrative story rules and film or story structure. In one example a selection of a few music tracks provides input audio signals (602) from which musical features are extracted (604), following which a dramatic parameter list and timeline are generated (606). Media fragments are then obtained (608), the fragments having story content associated with the dramatic parameters, and the fragments output (610) with the music selection.

Abstract: A method, apparatus, computer program, and computer readable storage medium storing the computer program, is disclosed for generating a real-world description to operate a set of devices (12, 14, 16) to augment a user's experience of a game world. The game world is defined by a game world model, and parameters of the game world model are accessed by a first module being run within a protected computing environment. These parameters are sent to a second module running outside of the protected computing environment, and the second module uses these parameters to generate the real world description for controlling the set of devices.

Abstract: A method of operating a set of devices comprises receiving a real-world description (30) in the form of an instruction set of a markup language, selecting a source of assets (32) for use by the set of devices, and operating the devices (34) according to the description. The source of assets can be a local store or a broadcast channel, or a combination of the two.

A predefined region (310) of a displayed screen (300) corresponding to said graphical data is captured and decoded to obtain a retrieved game play event that corresponds to the game play event, and an effect script corresponding to the retrieved game play event is determined. The effect script is provided to the effects devices (12, 14, 16, 112) to render ambient effects related to the game play event.
