20130074920 | Photo-Switchable Fullerene-Based Materials as Interfacial Layers in Organic Photovoltaics - Design and use of photo-switching, fullerene-based dyads of the design x-D-y-A or D-y-A-x as interfacial layers (IFL) for organic photovoltaic (OPV) devices are described herein. The fullerene-based dyads and triads of the present invention contain electron-donating substituents such as porphyrins or phthalocyanines that exhibit charge separation states with long lifetimes upon irradiation, resulting in rejection of electrons reaching the electrode and concurrently promoting the conduction of holes. This phenomenon has a strong rectifying effect on the whole device, not just the interfaces, resulting in improved charge extraction from the interior of the photo-active layer. The invention further describes anchoring an IFL to the ITO surface as a monolayer, bilayer, or greater multilayers. One OPV design embodiment of the present invention embodiment involves the formation of covalent bonds via silane groups (—SiR | 03-28-2013 |

When executed by a processor, the stand alone software objects defining the various batch interface views read data from and write data to the blackboard service to communicate data between batch process interface views and preserve contextual information between interface views to allow efficient and intuitive navigation between batch process interface views. | 04-08-2010 |
20100280630 | Compact Batch Viewing Techniques for Use in Batch Processes - A data collection and viewing application associated with a batch process control system used within a process plant provides a user interface that allows a user to quickly and easily examine a particular batch process or a batch run, to compare separate batch runs and/or to determine whether the particular batch run deviates from a norm, without having to perform a lot of manual data manipulation. To this end, the user interface provides or creates a compact graphical representation of a batch, illustrating a number of different types of batch-related data in relation to one another in a manner that enables a user to easily view or understand the operation of the batch run, either alone or as compared with one or more other batch runs. Generally speaking, the compact batch view includes a number of graphical layers which are juxtaposed or interleaved on a display, with each of the layers providing different types of information about the operation of the batch, time synchronized with one another. A base layer of the compact batch view may describe or indicate the duration of the batch from an activate time to a deactivate time, while different aspects of the procedural elements, steps or stages of the batch process, such as those identified by the S88 standard, may be illustrated in one or more additional layers. Moreover, process alarms, alerts, events, etc. as well as other information may be placed in one or more additional layers, and the various layers may be shown together to provide a compact graphical view of the batch. | 11-04-2010 |
