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 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 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.

Abstract: A method and electronic circuit for changing the gain of a radio frequency signal. The apparatus is an electronic circuit comprising one or more variable gain electronic elements, and one or more adjustable phase shifting elements. The method comprises the steps of receiving a radio frequency signal, varying the gain of the variable gain electronic element while the variable gain electronic element changes the amplitude of the radio frequency signal, and adjusting an adjustable phase shifting element to generate a reverse phase shift in the radio frequency signal in response to the associated phase shift from the step of varying the gain.
