Abstract: Systems and processes for accessing data from a graph database are described. The system receives a request comprising time-based information. Time-based information of the request is compared with a first time interval, which is associated with at least one node of a graph. The node of the graph is matched based on the time-based information being at least partially within the first time interval. The system returns a result comprising an indicator of the node of the graph, wherein the node of the graph is associated with an entity, and the node of the graph includes an attribute of the entity.

Abstract: Systems and processes for storing correlated data in a graph database are described. A first user node may be stored. In response to a request, a first event node and a second user node may be stored. The first event node may be associated with the first user node through an edge indicating participation. The first event node may be associated with the second user node through an edge indicating participation. In response to a content access, a second event node and a content node may be stored. The second event node may be associated with the first user node through an edge indicating participation. The second event node may be associated with the content node through an edge indicating usage. The first user node may be associated with the content node through an edge indicating the first user node handles the content node.

Abstract: Systems and processes for managing data in a data warehouse using an activity graph are described. The activity graph may include nodes representing entities (or versions thereof) interconnected by edges representing relationships (or versions thereof) between those entities. The nodes representing versions of an entity may be captured as a directed acyclic graph (DAG). New nodes and edges may be added to the activity graph as new entities and relationships are formed. As changes are made to an entity or relationship, new nodes or edges representing new versions of the entity or relationship may be created and added to the activity graph based on the entity's or relationship's tracking type. Existing nodes and edges may be removed from the activity based on data retention rules and/or data decay rules. In some examples, nodes and edges may be summarized by collapsing multiple nodes or multiple edges into a single node or edge.

Abstract: Systems and processes for presenting event notifications to a target user based on the context of the user are disclosed. The event notification can be selectively presented to the target user based on a comparison between the event and the context of the user. If the event and the context of the user meet predefined criteria, the event notification can be presented to the target user. If the event and the context of the user do not meet the predefined criteria, the event notification may be stored for later delivery to the target user.

Abstract: Systems and processes for displaying a graphical user interface control are described. API indicators may be displayed in response to a request for an API listing.

Abstract: Systems and processes for determining a contextual status of a resource, such as a user, using a contextual presence framework are described. A plurality of modes may be associated with the resource, where each mode represents a context of the resource. A presence value of the resource may be determined for each mode, which represents the extent to which the resource is engaged in the mode. An availability value of the resource may be determined for each mode, which represents the extent to which the resource is willing to be interrupted in the mode. A contextual presence status summary having a status summary availability value and a status summary presence value may be determined based on, for example, a weighted average of the presence values and a weighted average of the availability values of multiple modes of the resource.

Abstract: This invention pertains to a method of modifying the reproduction rate of cells by exposing the cells to north directional unipolar magnetic fields, thereby decreasing the reproduction rate of the cells. The reproduction rate of the cells can also be modified by exposing them to south directional unipolar magnetic fields, thereby increasing the reproduction rate of the cells.

Abstract: A method is provided for focusing magnetic fields, reducing magnetic fields and shielding animate or inanimate subjects from magnetic fields. Further a media which has been subjected to a shielded or focused magnetic field is applied to a subject, as for example, topically. The method, in part, interposes between the subjects and the source of a magnetic field, at least one second magnetic field disposed in such a manner that the polarity of the second magnetic field cancels or at least partially neutralizes the magnetic strength of the first magnetic field. The second magnetic field can also be disposed so as to permit only a portion of the first magnetic field to escape shielding and thereby focused in a predetermined direction. Devices which normally emit magnetic energy and containing the shielding of the present invention are also provided.

Abstract: The specification discloses a method and apparatus for servo-positioning moveable transducer heads and the like by means of time-based servo system utilizing a particular type of servo pattern or format recorded on a data storage member, e.g., magnetic tape or disk, and having first and second sets of servo lines that extend angularly across the recording media from opposite sides thereof convergently toward one another. The individual lines in each such set of recorded servo information extend alongside one another without intersecting, and in a preferred embodiment the two sets of servo lines intersect along a medial portion of the recording media, to define a uniform series of angles disposed adjacent one another along the recording member, a preferred such pattern having a chevron-like appearance. The overall servo pattern formed by the two sets of servo lines preferably extends across substantially the entire usable surface of the recording media to provide continuous servo-positioning.

Abstract: A positioning apparatus used for information-storage devices provides stoppage of a motor-driven transducer head-positioning lead screw follower as the follower approaches the motor-driven end of the lead screw. An element is provided on the follower which contacts a stop carried by the lead screw when the follower arrives at a position spaced from the motor by a predetermined distance, to thereby prevent the follower from moving any closer to the motor than such predetermined distance.

Abstract: A system for passing long fan-folded documents and corresponding copy paper through a reproducing apparatus and including a collapsible, upright stand which carries a pair of copy paper roll supporting elements, a pair of paper guide plates pivotally and detachably connected to the top of the stand, and a guide bar for guiding copy paper from a roll on the stand to the guide plates. The system further includes an improved, two-part feed tray detachably mounted on the reproducing apparatus. Each part is selectively positionable on the reproducing apparatus to facilitate containment of a fan-folded document to be reproduced. Each feed tray part includes a base plate having a downwardly extending strap to locate the tray on the reproducing machine, and at least one upwardly projecting stop rib spaced from a paper discharge slot at the front side of each tray part, and acting as an indexing abutment for contacting and positioning the fan-folded document in the tray.

Abstract: The specification discloses means for correcting timing variations present in a data stream emanating from a data storage device such as a magnetic tape drive or the like before the data stream is applied to the data separator or other such input device of a computer. This is accomplished by remodulating the time-varying bits in the data stream in a manner which reduces or eliminates the undesired timing variations. Basically, the system utilizes frequency-modulation techniques to in effect remodulate the raw data stream. The application discloses, as one preferred embodiment, a pulse-width modulator which receives the error signal output of a phase-locked loop network, the input of the pulse-width modulator being coupled to the incoming raw data stream.
