| 20080223481 | Fluid Dispensing System - A method and apparatus for supplying fluid wherein a product specific ticket, card, or order form is utilized which incorporates a bar code, notch or hole formed in the media thereof, a mark, a colored area, or a particular shape to designate the fluid type to be installed. | 09-18-2008 |
| 20080277000 | VALVE SYSTEM - A valve system for monitoring and controlling a flow of a fluid additive into a main fluid line is disclosed. The system includes a pump that provides a constant flow of the additive from a fluid reservoir through a supply conduit into the main fluid line. A portion of the fluid additive may be diverted into one or more return conduits leading back to the reservoir by opening a solenoid actuated valve in the return conduit. Flow meters are employed to detect the flow rates of the fluids in the supply conduit and the main fluid line. The flow meters provide signals to a control system, which are effective to control the operation of the solenoid actuated valves to maintain a desired flow of the additive into the main fluid line. | 11-13-2008 |
| 20090172963 | WEAR GAUGE - A gauge for measuring the wear of selected cooperating surfaces of an adapter is disclosed. The gauge includes a plurality of rollers adapted to contact the selected cooperating surfaces of the adapter. A trigger mechanism is provided to cooperate with the rollers to indicate if the adapter is out of tolerance in respect of given dimensional targets. | 07-09-2009 |
| 20100206097 | SYSTEM FOR COLLECTING A FLUID SAMPLE FROM A TRANSIENT LINE OF FLUID - A closed loop system for obtaining a sample of a fluid from a source of fluid is disclosed, the system including a collection vessel having a fluid chamber disposed therein. A valve assembly is disposed within the collection vessel and adapted to selectively open and close a fluid communication path between the fluid chamber and an associated fluid receptacle. An inlet provides a fluid communication path between the source of fluid and the fluid chamber, and an outlet provides a fluid communication path between the fluid chamber and a fluid recovery system. | 08-19-2010 |
| 20120080095 | VALVE SYSTEM - A valve system for monitoring and controlling a flow of a fluid additive into a main fluid line is disclosed.

| 20080213741 | DISTRIBUTED LEARNING PLATFORM SYSTEM - A system for distributing educational information includes compiling educational information from educational sources. The user connects to a management system through a network connection. A user account may be authenticated with a user identification. The management system then transmits a plurality of educational material that may be used and operated on the user's computer when the user is offline. Later, the management system performs a sync operation when the user is able to reconnect to the system. | 09-04-2008 |
| 20080215670 | TRACKING USAGE AND MONITORING USERS OF A DISTRIBUTED LEARNING SYSTEM - A system for monitoring and tracking the distribution of educational information in a distributed learning environment includes allowing a user to connect to a management system through a network connection. The management system transmits a plurality of educational material that may be used and operated on the user's computer when the user is offline. The management system performs a sync operation when the user is able to reconnect to the system. After each transfer and/or sync operation, the management system stores data associated with the outcome of the transfer and/or sync, wherein the data may be used to monitor a student's progression through a course and to track diagnostic problems in a user's computer. | 09-04-2008 |
| 20080215731 | ATTRIBUTE GROUPING FOR ONLINE COURSE - In an online computing system for providing a user with access to educational content in an online educational system, wherein the educational content includes access information. The method comprising organizing a hierarchy of user groups and domains, associating the user with a group or domain, receiving a request from a user to access educational content in the online educational system, retrieving information relating to the user's group or domain associations, retrieving the access information of the educational content that the user has requested to access, comparing the access information with the information relating to the user's group or domain associations, and determining whether the user has been authorized to access the requested educational content. | 09-04-2008 |
| 20090068629 | DUAL OUTPUT GRADEBOOK WITH RUBRICS - A system and method for assessing a student's performance in a course in an online course environment, the method comprising creating rubrics that correlate with course materials for an online course, the rubrics including a scoring schema which is stored in an educational management system, distributing the rubrics from the educational system to a user's computer through a network connection, displaying the rubrics on the user's computer together with their correlating course materials, recording the outcome of a student's performance on the rubrics, the outcome including a grade associated with a student, and transferring the recorded outcome to the educational management system. | 03-12-2009 |
