Title: Synchronised event system
Filed: 2011-04-26
Abstract: An event control system in which identical or similar events, operated by different. users or operated at different locations, are synchronised to operate independently. Each user or location having its own copy of the event item. An event item including a media content item or non-media item such as control system components, computer system components, pneumatic or hydraulic components, electromechanical components. Each user or location does not need to be connected to each other. All users operate in time synchronisation. The playback time is adjusted to allow synchronisation of the events which may be located at different locations. The system may compensate for a delay in starting playback of media content to determine a start time and playback may jump to the current time position in an item, itinerary or playlist.

Title: Control of a machining operation
Filed: 2011-08-03
Abstract: A method for controlling the machining of a component is provided. The method incorporates closed-loop control based on feedback of measured parameters. The method includes the steps of: (i) measuring predetermined dimensions of a component; (ii) comparing the measured dimensions against design data defining a required shape for the component; (iii) using the results of the comparison to define material removal that is needed to bring the component to the required shape; (iv) delivering the component to a site at or adjacent to a machining station having a material removal tool (24), the component being gripped by a robotic manipulator (22) at said site; (v) using the defined material removal and the known position of the robotic manipulator at the machining station to determine movements of the material removal tool that will produce the required shape for the component; and (vi) performing a machining operation on the component at the machining station using the determined movements while maintaining the grip on the component by the robotic manipulator. The method further includes: the step, between steps (iv) and (v), of measuring the position of the gripped component and/or the robotic manipulator at said site to determine errors in the position of the robotic manipulator; and using the determined errors in the previous step to improve the accuracy of the known position of the robotic manipulator at the machining station.

Title: Improvements in or relating to feed forward equilisation
Filed: 2011-11-29
Abstract: A serialiser/deserialiser (SERDES) receiver 11 comprises a feed forward equaliser (FFE) 4 and a decision feedback equaliser (DFE) 5 acting as a data slicer. The FFE makes an estimate of a future sample by slicing the future sample with respect to a predetermined slicing level and corrects a current sample for the effect of the future sample before it is sliced by the DFE. The FFE subtracts at least one quantising level from the current sample if the future bit is rendered as a 1 or adds at least one quantising level if the future bit is rendered as a 0. The receiver is arranged such that the subtraction and addition are performed only if the bit values of the current and future samples as rendered by the FFE are different. The invention prevents the FFE from applying a correction that is adverse to noise margin and bit error rate by moving the current sample value closer to the data slicing level of the data slicer.

Title: Analog-to-digital converter
Inventor: HARRISON WILLIAM D
IPC: H03M1/00
Filed: 1980-06-04
Granted: 1984-06-14
Abstract: An analog-to-digital conversion system uses a fast analog-to-digital converter having a resolution less than the system resolution to convert the difference between a previously predicted value and the current analog value. The converted difference is summed with the predicted value to compute the actual value of the analog input signal to a resolution greater than that of the fast analog-to-digital converter. The high resolution digital value thus obtained becomes the predicted value for the next conversion. This predicted value is converted by a digital-to-analog converter having the same accuracy but not the same resolution as the system output to an analog signal which is compared with the input analog signal to obtain a difference signal. This difference signal is sampled and held to provide the input to the fast analog-to-digital converter. The system includes a gain scaling and switching circuit to compensate for errors which would occur when the difference between the true analog input and the prediction exceeds the range of the low resolution, fast analog-to-digital converter.
