  • Patent number: 8412359
    Abstract: The invention relates to the automatic rendering of a lighting scene with a lighting system, particularly the control of the rendering. A basic idea of the invention is to improve rendering of a lighting scene by automatically compensating interference, such as an alien light source or a dynamic perturbing event of a rendered lighting scene. An embodiment of the invention provides a light control system (10) for automatically rendering a lighting scene with a lighting system, wherein the light control (10) system is adapted for monitoring the rendered lighting scene for the occurrence of interference (14, 20, 22, 24) and automatically reconfiguring the lighting system such that a monitored occurrence of an interference is compensated (16, 18, 12). As result, the invention allows to prevent dynamic disturbances or unforeseen events, for example caused by faulty or alien light sources, from distorting the rendering of an intended lighting scene.

    Abstract: A method includes identifying one of multiple regions in a range where an output (OP) value used to implement a manipulated variable is located. The manipulated variable is associated with an industrial process, and the OP value represents an output of a downstream controller. The method also includes calculating an achievable manipulated variable (MV) limit for the manipulated variable based on the region in which the OP value is located. For example, when the OP value is located in one region, the achievable MV limit could match a user-specified limit or be based on a gain between the OP value and a value of a process variable. When the OP value is located in another region, the achievable MV limit could track the value of the process variable with a gap.

The current values of the applicable process variables (Qa-Qh) during each phase and the phase identifier (p) are indicated on respective axes (Xp,Xa-Xh) of a multi-dimensional display in relation to an operational envelope which defines bounds (UL,LL) for the values of the individual process and quality variables (a-j) relevant to that phase and which is derived from the datasets of the historical record identified with that phase. Changes in the current process variables (Qa-Qh) result in changes of the bounds (UL,LL), and alarm is given when a current value departs from within them.

  • Publication number: 20130024013
    Abstract: Information from a real sensor and a virtual sensor are fused to form a hybrid sensor. Control signals (and/or the absolute value of the control signals) applied to an actuator are accumulated and converted to a position the actuator should be in based on the accumulated control signals to form the virtual sensor. The actuator position from the virtual sensor is fused with an actuator position from a real sensor to form the hybrid sensor. Small periodic corrections can be made to the accumulating control signals to maintain or achieve, if possible, correlation between the virtual sensor and the real sensor over time. The corrections slowly decrement errors in the actuator position indicated by the virtual sensor. Accumulating numerical errors in the accumulating control signals are reduced and the significance of long past events is de-emphasized by a forgetting factor (kff) used at defined periods of time (tff).

The machine vision system includes an optical imager aligned to simultaneously capture an image that contains a view of the side of an object, such as a test tube, along with a view of the top of the object provided by a mirror appropriately positioned on the robotic arm. The machine vision system further includes a microcontroller or similar device for interpreting both portions of the image. For example, the microcontroller may be programmed to determine the location of the object in the reflected portion of the image and transpose that information into the location of the object relative to the robotic arm. The microcontroller may also be programmed to decode information positioned on the object by interpreting visual information contained in the other portion of the captured image.

  • Patent number: 8311653
    Abstract: One method includes obtaining a preliminary model associated with a system to be controlled and constructing a weighted model using one or more weighting factors. The method also includes identifying a final model of the system using the preliminary and weighted models, where the final model has a stability margin that is greater than an uncertainty associated with the final model. The method further includes controlling the system using a controller designed based on the final model. Another method includes identifying a first model associated with a system to be controlled, performing model order reduction to identify a second model, and controlling the system using a controller designed based on the second model. Performing the model order reduction includes reducing a weighted coprime factor model uncertainty between the first and second models.

  • Patent number: 8306928
    Abstract: A system and a method are used for maintaining and analyzing manufacturing equipment. The system includes an embedded forecast device (EFD) configured in the manufacturing equipment and a server in communication with the EFD. The EFD is built in with a feature extraction (FE) algorithm and a forecast model (FM), so as to obtain a real time data of the manufacturing equipment and carry out forecasts on the manufacturing equipment to generate a forecast result. The server has various types of FE algorithms and modeling algorithms, which are selected and combined by a user for training and building a required FM and setting related parameters. The embedded forecast device also has a novelty detection model (NDM), which is capable of informing the server to retrain the models when the manufacturing equipment fails and then to update the FM and the NDM of the embedded forecast device.

  • Patent number: 8295951
    Abstract: Techniques, systems and methods for designing, implementing, and operating model predictive controllers that can deliver perfect tracking of set points and that can reject the effect of disturbances when steady-state operation is reached are disclosed. High performance is achieved through the incorporation of set-point tracking costs, integral costs, and velocity costs, as well as the adoption of incremental model systems for prediction purposes. Embodiments can deliver offset-free performance for tracking set points with constant final values, set points of a ramp type, and set points of a parabolic form, while rejecting disturbances that have a constant final value. The approach reduces the complexity of model predictive control design, delivers improved performance, and requires modest computational power.
