Abstract: A computer-implemented method includes determining that a specific type of information is to be identified in a set of data. The method further includes sampling the set of data according to various sampling criteria to identify the specified type of information. The sampling criteria include at least a recency criterion indicating that the data to be sampled has been updated within a specified timeframe and a lineage criterion indicating that the data to be sampled is within a maximum hierarchical distance from a source data structure. The method also includes identifying, from the data that was sampled according to the sampling criteria, one or more data structures that include the specified type of information. The method further includes applying security policies to the identified data structures based on the type of information that was identified in the set of data. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A baffle for a membrane device. The membrane device includes a membrane, a feed flow inlet, and a feed flow outlet, such as for water filtration. The baffle includes a proximal end and a distal end, wherein the baffle is operable to extend along at least a portion of the membrane so that the proximal end is toward the feed flow inlet of the membrane device and the distal end is toward the feed outlet of the membrane device. The baffle includes a first geometry portion and a second geometry portion. The first geometry portion includes a higher aspect ratio than the second geometry portion and the first geometry portion is arranged closer to the proximal end of the baffle than the second geometry portion. Also described is a method of producing the baffle and a membrane device containing the baffle.

Abstract: A plurality of different controllers on an agricultural machine are time synchronized. A first controller, identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, and generates a timestamp indicating a time at which the action is to be taken. An action identifier and the timestamp are sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the timestamp based upon the actuator delay.

Abstract: A dispensing machine dispenses a material on a field. A blockage is detected, and an initial blockage location, where the blockage started, is identified. A blockage characterization system identifies characteristics of the blockage, and a control signal generator generates control signals based upon the detected blockage, and the characteristics of the blockage.

Abstract: A plurality of different controllers on an agricultural machine are time synchronized. A positioning system detects a geographic location and a timestamp, which is indicative of a time when the geographic location was sensed, is applied to the geographic location. A first controller, that identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, generates a future timestamp indicating a future time at which the action is to be taken. An action identifier (that identifies the action) and the future timestamp is sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the future timestamp based upon the future timestamp, a current time, and the actuator delay.

Abstract: A test pattern (170) comprising a set of dots (174) which define a first ellipse (176) of best fit in which the major and minor axes R1, R2 are equal (i.e. a circle) is displayed on a plane surface and a digital image of the (usually distorted) test pattern seen through a lens is captured. A second ellipse of best fit joining the dots in the set is derived from the distorted test pattern in the image. Characteristics of the first and second ellipses are compared to determine the degree and nature of distortion to the test pattern, from which the power of the lens is calculated. The major and minor axes of the first and second ellipses may be compared. The test pattern can include a number of said sets of dots distributed over an area of the surface with each set being analysed to determine the optical parameters of the lens at multiple locations.

Abstract: A data processing system and method for assembling components in a computer-aided design (CAD) environment is disclosed. In one embodiment, a computer-implemented method of assembling components in a CAD environment includes determining, using a data processing system, a source component and a target component in the CAD environment. The source component and the target component represent different parts of a real-world object. The method includes determining geometric feature(s) of the source component and geometric feature(s) of the target component, and comparing the geometric features of the source component with the geometric features of the target component. The method includes generating constraints between the geometric features of the source component and the geometric features of the target component based on the outcome of the comparison. The method also includes outputting a geometric model of the assembled source component and target component on a graphical user interface.

Abstract: A system (101) for examining lenses in a pair of glasses includes a tablet computer (112), a camera (128) mounted above the computer screen and a glasses mount (156) for holding a lens in a pair of glasses between the camera and the display screen. The camera (128) is operatively connected to the computer for storing and processing image data captured by the camera. In use, a test pattern is displayed on the screen below the camera and an image of the test pattern seen through a lens is captured by the camera. Image data is saved to the computer which processes the data to determine the power of the lens from the distortion to the test pattern caused by the lens. The results are displayed on another section of display screen. The camera mount (156) may be a plinth slidably positioned on the display screen.
