Abstract: Sensor information is regularly acquired from a plurality of sensors and stored. For each of the sensors, other sensors whose information is correlated are selected. When sensor information of a sensor is requested from an application program or the like, while if the requested sensor is available the sensor information is acquired directly from the sensor, if the requested sensor is unavailable the sensor information of sensors relevant to the sensor is acquired and the sensor information of the requested sensor is estimated. As a result, in a system comprising a plurality of sensors, sensor information of an unavailable sensor will be estimated in a short period of time.

Abstract: Methods for processing signals from a magnetic user interface device having a manual actuator are disclosed. Movements of the actuator may cause relative movement between one or more magnets and one or more corresponding sensors that may each generate signals representing independent magnetic field components detected within each sensor. A field model may be used in the magnetic user interface device to translate magnetic sensor readings during operation to position information, which may then be converted to output signals for transmission to an electronic computing system representing displacement and/or deformation of the actuator. The output signals may be generated in a predetermined format, such as USB format or other computer-interface formats, that can be interpreted by the electronic computing system.

Abstract: A building management system (BMS) includes a controller that monitors performance values for a controlled process during a first time period relative to initial outlier detection limits and generates new outlier detection limits for the controlled process in response to a detected change in the controlled process during the first time period. The controller monitors the performance values relative to the new outlier detection limits during a second time period to detect outliers during the second time period. The controller calculates a confidence difference for an estimated confidence parameter based on a number of outliers detected using the new outlier detection limits during the second time period. The controller adjusts the new outlier detection limits in response to the confidence difference dropping below a threshold value.
