A classification of a container is identified using a mobile station including an image capture device and an RFID reader having a reader antenna. The container has two RFID tags affixed thereto at respective, different locations. Each tag has a directional antenna steered in a different direction, so that a reader location is defined in the intersection of the antenna propagation patterns. Using the image capture device, one or more images of the container are captured. A controller determines, using the captured image data, whether the mobile station is in a candidate reader location. When the mobile station is in the candidate reader location, the RFID reader attempts to read both tags. If both tags are read while the mobile station is in the candidate reader location, the controller determines the classification of the container is a classification corresponding to the candidate reader location.

A method for reconciling a source data graph with a target data graph, the source graph and the target graph each comprising: and a interconnections, the interconnections each connecting two vertices from and representing a relationship between the connected vertices. The method comprises: generating target event propagation information representing the propagation pattern of executions of each of a set of processing events in the target graph; receiving a request to reconcile the source and graph, and in response to the request, triggering the executions of each of the set in the source graph; generating source event propagation information representing the pattern of each of the executions triggered in the source graph; and using the target event propagation information and the source event propagation information to assess the similarity of pairs of vertices comprising one vertex from each of the source graph and the target graph.

A PIN electro-optical traveling wave modulator (10) including diffraction gratings (34, 36) positioned at opposing sides of an optical waveguide (20) that act to change the propagation pattern of the waveguide (20). The modulator (10) includes an N-type layer (14), a P-type layer (18) and an intrinsic layer (16) acting as the waveguide (20). A metal electrode (26) is in electrical contact with the N-type layer (14), and a metal electrode (30) is in electrical contact with the P-type layer (18). The electrodes (26, 30) define an RF transmission line. An optical wave (22) propagates along the waveguide (20) and interacts with the gratings (34, 36) which slow the optical wave (22) to match its speed to the speed of the RF wave in the transmission line. In one embodiment, the gratings (34, 36) are 2-D gratings formed by vertical holes (38) in the waveguide (20).

Method and system is described for modeling one or more geophysical properties of a subsurface volume. The method includes extracting locations from the data volume and combining them into an object, for example a horizon. The extraction may begin with selecting one or more initial traces, assigning labels to each sample of each trace, selecting a propagation pattern, and propagating the labels from the initial traces along a vector volume. Then, locations with the same label are extracted (1106). As an alternative to label propagation, a specific type of labeled volume (1102) may be obtained, such as a stack of surfaces (1132). The object may then be further modified or utilized to enhance the process of producing hydrocarbons.

A servo system wherein a read head R detects a servo pattern that is written on a magnetic disk by a write head W. Position control of the write head W is exercised in accordance with the detected servo pattern, and the read head R detects a propagation pattern that is written on the magnetic disk by the write head W. Position of the write head W is corrected in accordance with the detected propagation pattern.

The present invention discovers a characteristic correlation of propagation patterns to users between contents, the correlation being usable for information recommendation or marketing analysis. In the information recommendation, for example, a content is recommended at a proper timing of propagation. This content analyzing system comprises: a user terminal (200); and a content analyzing apparatus (100) for receiving a predetermined request from the user terminal (200) and returning the result thereof. The content analyzing apparatus (100) comprises: a propagation pattern extraction means (102); and a correlation calculation means (103). The propagation pattern extraction means (102) extracts a propagation pattern indicating how the content has been propagated to the user, for each content included in history data including use history of a plurality of contents. The correlation calculation means (103) obtains the correlation of the propagation patterns between the contents.

The invention discloses a three observation station data feature point-based ionospheric disturbance propagation measurement method and system. The method includes the following steps that: a local coordinate system is built, monitoring data feature points are selected, and time when an anomaly arrives at three points is obtained, and the propagation time difference of anomaly disturbance is obtained; and the slope of an anomaly propagation path and the coordinates of projection points in a disturbance propagation direction are calculated, and the propagation velocity and azimuth angle of the anomaly are calculated, and measurement results are obtained. According to the three observation station data feature point-based ionospheric disturbance propagation measurement method and system of the invention, the velocity and direction of ionospheric disturbance propagation can be accurately and automatically calculated with only a small number of feature points based on the precise geometrical relationships of observation station puncture points under a condition that ionospheric disturbance time is short. The three observation station data feature point-based ionospheric disturbance propagation measurement method and system have great scientific significance and application value for the study of the solar-terrestrial space environment, ionosphere, magnetosphere coupling and traveling ionospheric disturbance propagation patterns.

Method and system are described for generating a stratigraphic model of a subsurface volume. Measured geophysical data are converted into a vector volume (106) by assigning to each sample in each trace in the data volume a vector representing dip, azimuth or confidence. Then a labeled volume is generated from the vector volume by assigning a label to each sample in an initial trace (1006), then selecting a propagation pattern (1008) and propagating the labels to other traces (1010). Horizons can be extracted (110) from the labeled volume, and utilized to enhance the process of producing hydrocarbons (114).
