20100133744 | Media Sheet Guide Device and Method for Maintaining Proper Sheet Alignment in an Image Forming Machine - A media sheet guide device for maintaining proper sheet alignment in an image forming machine includes a body extending between spaced apart reference edges of respective upstream and downstream media alignment mechanisms and a face on the body defining a path along which a sheet moves lengthwise from the upstream reference edge to the downstream reference edge. The face has a section extending widthwise and defining a portion of the path about which the sheet bends widthwise as the sheet moves lengthwise along the path portion. The face section has first and second segments differing in curvature for applying a differential drag widthwise across the sheet causing a rotation of the sheet sufficiently to displace a leading end of the sheet away from the downstream reference edge to thereby ensure that a leading corner of the sheet can enter into the downstream reference edge without jamming against an entry end thereof. | 06-03-2010 |

20090063454 | VORTEX SEARCHING - Determining intersection points of parameter patterns. Parameter patterns are specified in a query. A method includes identifying a first parameter pattern from the query as occurring less often in the index than one other parameter pattern in the query. The data store is searched until a present location of the data store has been identified as including the first parameter pattern. Then the data store is searched for a location of another parameter pattern. If the present location is identified as including the another parameter pattern, then an indication is provided identifying an intersection. Otherwise, the method includes continuing searching remaining portions of the data store to find a location of the another parameter pattern at a new present location. At least one of the acts of searching above includes eliminating at least a portion of records of the data store from searching without being searched prior to being eliminated. | 03-05-2009 |
20090063479 | SEARCH TEMPLATES - Searching a data store for parameter patterns specified in a query. A method includes receiving a query from a user including N parameter patterns. One or more alternatives are associated to one or more of the N parameter patterns. One or more templates are created. Each of the templates describes a number of microsearches. Each of the microsearches includes one or more of the N parameter patterns or the alternatives. Microsearches described by at least one of the one or more templates are enumerated. One or more sub-microsearches are performed by searching for parameter patterns and/or alternatives. Each sub-microsearch may have less than all terms needed for a full microsearch. Based on the results of the one or more sub-microsearches, one or more microsearches are eliminated from searching. The data store is searched using one or more of the remaining microsearches. | 03-05-2009 |
20090307184 | Hyperspace Index - Hyperspace index data structure. A data structure indexes identifiers corresponding to parameter patterns.

The data structure includes a first field which includes binary bits or groups of small parameter pattern keyed records. Each binary bit or parameter pattern keyed record corresponds to an identifier corresponding to a parameter pattern. If the bit or record corresponding to the identifier is set or present, the identifier is included in the first field. One or more additional fields are hierarchically below the first data field. Each of the additional fields includes identifiers for a subset of information in the first field. The absence of an identifier corresponding to a parameter pattern at any level in all of the hierarchical threads indicates that the parameter pattern is not present. | 12-10-2009 |

20100143873 | APPARATUS AND METHOD FOR TASK BASED LANGUAGE INSTRUCTION - A computer-implemented system and method for teaching a target language are disclosed that may include providing a pool of tasks associated with instruction of the target language by a computing system; receiving a query from a user requesting instruction of a target task from among the pool of tasks; identifying a sequence of tasks beneficial for teaching the target task; and presenting a lesson plan, including the beneficial sequence of language tasks, to the user in response to the user query, wherein the lesson plan includes the target task and at least one supporting task. | 06-10-2010 |
20100143874 | LANGUAGE SKILLS TEACHING METHOD AND APPARATUS - A student providing a multi-word response in a computerized language teaching system provides a manual input concurrently with each responsive word. For example, he might enter a keystroke correspondent to the first letter of each word. When using the teaching computer silently, a student will typically “speak” each word mentally as he enters a keystroke, so the limited experience is almost as effective as speaking out loud. When a student types one or more keystrokes concurrently with each word that he speaks, the computer will be able to detect when a student is responding with a correct word, but merely mispronouncing it. Also, since the computer will receive a keystroke as the student starts each new word, it is better able to distinguish the boundaries between words and recognize them more reliably. | 06-10-2010 |
20120288833 | System and Method for Language Instruction Using Multiple Prompts - A method of teaching a language to a student by an instructor is disclosed, wherein the method may include the steps of the instructor uttering a first prompting phrase to the student; receiving a first response from the student in response to the first prompting phrase; modifying at least one characteristic of the first prompting phrase to generate a second prompting phrase; and the instructor uttering the second prompting phrase to the student, wherein at least one of the above steps is performed using a computer. | 11-15-2012 |
20140170610 | METHOD AND SYSTEM FOR CREATING CONTROLLED VARIATIONS IN DIALOGUES - A method and system for teaching a user a target language includes developing and constructing variable potential paths of nodes representing an exchange between two participants in a dialogue, prompting and selecting a path of nodes through a conversation graph of the target language, the path of nodes defining a dialogue; and determining whether the user is ready to perform the dialogue that has been constructed and defined by the path of nodes, the determination being based on a user model which represents the user's current ability in and current knowledge of, the target language. If the user is ready to perform the dialogue, the path of nodes is executed to allow the user to perform the dialogue defined thereby; and if the user is not ready to perform the dialogue, training the user on one or more nodes of the path of nodes. | 06-19-2014 |
20140170629 | PRODUCING CONTROLLED VARIATIONS IN AUTOMATED TEACHING SYSTEM INTERACTIONS - The content of an instructor-student interaction set in an automated teaching system is represented in a graph-based format. In a graph-based representation, not only can variations branch away from each other at a node (branching point), as in the tree-based representation, but they can also merge back together. Not only does this make the -structure more compact, but it increases the number of variations that can be represented in the content while simultaneously eliminating the need to individually author each variation. | 06-19-2014 |
