International Classification:

G06F 19/00

US Classification:

700 83, 700 28, 705401

Abstract:

A configuration system for a process plant uses module class objects to assist in configuring, organizing and changing the control and display activities within the process plant. Each module class object generically models or represents a process entity, such as a unit, a piece of equipment, a control activity, etc. , and may be used to create instances of the object, called module objects, which represent and are tied to specific equipment within the process plant. The module class objects may represent process entities of any desired scope, which means that a single module class object may be used to configure the control and display activities of process entities of any desired scope within the process plant, instead of just at a control module level. In particular, module class objects of a large scope may be used to configure large sections or portions of the process plant, which makes configuration of the process plant easier and less time consuming. A module class object may be a unit module class object reflecting a physical unit within the process plant, an equipment module class object reflecting a physical piece of equipment within the process plant, a control module class object reflecting a control module or scheme within the process plant, or a display module class object reflecting a display routine that provides information to a user within the process plant.

International Classification:

G05B 9/02

US Classification:

700 83, 700 28, 719315, 707103 Y

Abstract:

A version control system helps to keep track of versions of process plant items that may represent, or be capable of representing, entities in a process plant. The process plant items may comprise, for example, module objects which may be capable of specifically representing process entities of the process plant. These module objects may be created from module class objects which may be capable of generically representing process entities of the process plant. Version data is stored and associated with a module object. The version data may comprise data indicative of a version of a module class object that was used to create the module object. The version data may also comprise data indicative of a version of the module object. Configuration systems, version control systems, viewing systems, debugging systems, run-time monitoring systems, asset management systems, etc. , may examine or permit viewing of the version control data associated with an item.

11/227989

Inventors:

Shun Lien Chuang - Urbana IL, US
Jian Li - Pasadena CA, US
Rui Q. Yang - Valencia CA, US

Assignee:

California Institute of Technology - Pasadena CA

International Classification:

H01L 27/14

US Classification:

257431, 977820, 257E31001

Abstract:

A device for detecting radiation, typically in the infrared. Photons are absorbed in an active region of a semiconductor device such that the absorption induces an interband electronic transition and generates photo-excited charge carriers. The charge carriers are coupled into a carrier transport region having multiple quantum wells and characterized by intersubband relaxation that provides rapid charge carrier collection. The photo-excited carriers are collected from the carrier transport region at a conducting contact region. Another carrier transport region characterized by interband tunneling for multiple stages draws charge carriers from another conducting contact and replenishes the charge carriers to the active region for photo-excitation. A photocurrent is generated between the conducting contacts through the active region of the device.

Abstract:

A configuration system uses process plant items that may represent, or be capable of representing, entities in a process plant to assist in configuring, organizing, and changing the control and display activities within the process plant. Access to the items may be controlled by associating access control data with the items. The configuration system may also use objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant. Access to these objects may be controlled by associating access control data with the objects. The access control data may indicate whether users or certain users may be able to, for example, view or modify all or some data associated with the process plant items or the objects. The process plant items may comprise, for example, module class objects which may be capable of generically representing process entities of the process plant, module objects which may be capable of specifically representing process entities of the process plant, composite templates, module templates, etc. The objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant may comprise, for example, phase classes or unit phases.
