  • Publication number: 20210014952
    Abstract: A calibration and daylighting control system provides a predetermined lighting level at a work surface. The system preferably includes a light sensor and a load control device for controlling a connected lighting element to provide light to the associated area and a work surface located therein. A wireless transceiver can provide wireless communication with a portable remote device such as a smart phone. A processor can be coupled to the light sensor, load control device and transceiver. The processor may be programmed to receive, via the transceiver, wireless signals from the portable remote device when the remote device is positioned on the work surface, and set a daylighting level of the light sensor based on the wireless signals. The wireless signals can be indicative that the daylighting level of the light sensor corresponds within a predetermined amount to the user-selected lighting level at the work surface.

  • Patent number: 8417496
    Abstract: A computer system for modelling and controlling a hydrocarbon reservoir through management of fluid flow at individual wells. The computer system has program instructions which operate a computer model which uses oilfield production data to provide a model of future production. The model comprises an optimal regression model which represents injector and producer wells whose fluid flow characteristics are highly correlated with the fluid flow characteristics of the well of interest; the application of parsimonious information criterion techniques to identify well pairs that statistically contribute information to the optimal regression model; and a statistical reservoir model comprising the product of the optimal regression model and a significance matrix. The system is also provided with control means, responsive to the output of the computer model in order to control wells in the hydrocarbon reservoir.
