Approaches for three-dimensional object display used in content navigation
Approaches enable three-dimensional (3D) display and interaction with interfaces (such as a webpage, an application, etc.) when the device is operating in a 3D view mode. For example, interface elements can be highlighted, emphasized, animated, or otherwise altered in appearance, and/or arrangement in the renderings of those interfaces based at least in part on an orientation of the device or a position of a user using the device. Further, the 3D view mode can provide for an animated 3D departure and appearance of elements as the device navigates from a current page to a new page. Further still, approaches provide for the ability to specify 3D attributes (such as the appearance, action, etc.) of the interface elements. In this way, a developer of such interfaces can use information (e.g., tags, CSS, JavaScript, etc.) to specify a 3D appearance change to be applied to at least one interface element when the 3D view mode is activated. |

This method utilizes only mechanical information to identify surge, as compared to present day antisurge controllers that use compressor thermodynamic information such as flow, pressure, and temperature to locate a compressor's operating point on a compressor map compared to a surge region. |

Compressed air system and method of operating same
An improved compressed air system utilizes one or more base compressors, such as fixed speed drive compressors, to meet the compressed air demands and one or more trim compressors, such as variable speed drive compressors, to meet the variations in the demand.

The control may spread the demands over the various base compressors to improve the overall loading on each base compressor. Efficiency metrics may be utilized to control the switching between base and trim compressors. Unloading of a base compressor may be controlled to avoid undesirable changes in system performance. |
