  • Patent number: 10064312
    Abstract: A data center includes a computer room with one or more regions, where each region includes air handling components which can be independently controlled, relative to components in other regions. A purge control system in each region can bypass a control system which adjusts the components based on environmental sensor data to command the components to purge the region. Upon the components in a region entering a purge mode, a purge notification signal can be sent to a master control system, which can instruct other control systems in other non-purging regions to limit controller output ranges to last-known values prior to the purge, so that the components in other regions are operated at last-known states while one or more regions are purging. When regions have ceased purging, the regional control systems can re-establish the control loop output ranges. Such re-establishment can include incrementally expanding the output range over time.

  • Patent number: 10018979
    Abstract: Device and method for the detection and/or diagnosis of faults in a process, equipment and sensors used to measure and control variables of a process, either for single faults or multiple faults. The detection and/or diagnosis are performed on the basis of residual calculation between measured values and values calculated by a plurality of parallel linear models, built up from the existing correlations between the measured variables by the process sensors and by different equations that rule the process, such as mass and heat balances, quality relationships, etc. A fault in a model (i.e. the obtainment of a residual anomaly high by comparing the model estimation and the measurement), increases the probability that some of the parameters or faults associated to that model are failing. When all models in which a participating parameter fail or show a high probability of failure, the anomaly rate of said parameters is maximum.

  • Patent number: 10021537
    Abstract: [Problem] To provide a wireless communication network system and a method for determining a representative sensor device for appropriately selecting, from a plurality of sensor devices, a device with which a server communicates. [Solution] A server (120) transmits a group representative determination request including a list of parameters for determining a representative sensor device. Sensor devices (140a-z) transmit, upon receiving the parameter list, a device parameter indicating the parameter of each of the sensor devices corresponding to the parameter list. The representative sensor device is determined on the basis of the device parameters transmitted by the sensor devices (140a-z). The representative sensor device transmits, to the server (120), measurement result information generated by the sensor device itself and measurement result information generated by the other sensor devices.

  • Patent number: 10012966
    Abstract: An EMS (30) is equipped with a control unit (31) for obtaining a first measurement value which indicates an operating state of an apparatus (11) at a predetermined time point and at least one second measurement value which indicates an operating state of the apparatus (11) at a time point earlier than the predetermined time point. The control unit (31) calculates a first reference value, which indicates a reference for the operating state of the apparatus (11), by using the second measurement value and determines the presence/absence of an anomaly of the apparatus (11) on the basis of a comparison result between the first measurement value and the first reference value.

  • Patent number: 9971318
    Abstract: A method includes obtaining information identifying (i) uncertainties associated with multiple time-domain parameters of a model and (ii) time-domain performance specifications for a model-based industrial process controller. The model mathematically represents a MIMO industrial process. The method also includes generating multiple tuning parameters for the controller based on the uncertainties and the time-domain performance specifications. The tuning parameters include vectors of tuning parameters associated with the controller, and each vector includes values associated with different outputs of the industrial process. The time-domain parameters could include a process gain, a time constant, and a time delay for each input-output pair of the model. The time-domain performance specifications could include requirements related to worst-case overshoots, settling times, and total variations. The uncertainties could be specified as intervals in which the time-domain parameters lie.

  • Patent number: 9965802
    Abstract: A method for generating bids for a look-ahead, e.g. hour-ahead, energy market is disclosed. The method includes providing a processor configured to generate a lookup table approximating a value function having four dimensions including: state of the storage system, price of electricity, prior low bid and prior high bid. The processor is configured to observe an initial numeric value for a first set of dimensions and exploiting monotonicity to update a first region of the lookup table. The processor is configured to iteratively observe subsequent numeric values for a next set of dimensions and update subsequent regions of the lookup table while exploiting monotonicity to generate the lookup table. The value function is configured with numeric values for all possible sets of dimensions, the numeric values being usable to compute optimal bids.

  • Patent number: 9918700
    Abstract: Values for ultrasound acquisition parameters are altered in a manifold space. The number of parameters to be set is reduced using a manifold. Virtual parameters different than the acquisition parameters are used to alter the greater number of acquisition parameters. In a further use, optimum image settings may be obtained in an automated system by measuring image quality for feeding back to virtual parameter adjustment.

  • Patent number: 9857782
    Abstract: A first acquiring unit acquires initial output values of a physical quantity sensor. A second acquiring unit acquires target output values for the physical quantity sensor. A first calculating unit extracts first characteristic values by calculating a second-order first characteristics formula which indicates corrected output characteristics of the physical quantity sensor, based on the initial output values and target output values of the physical quantity sensor. The second calculating unit extracts second characteristic values by calculating a second-order second characteristics formula for correcting the first characteristic values, based on a predetermined temperature and the first characteristic values. A computing unit computes a corrected output value for the physical quantity sensor based on the first characteristics formula which is corrected by inputting the second characteristic values to the second characteristics formula.

  • Patent number: 9817375
    Abstract: According to various implementations, a demand response (DR) strategy system is described that can effectively model the HVAC energy consumption of a house using a learning based approach that is based on actual energy usage data collected over a period of days. This modeled energy consumption may be used with day-ahead energy pricing and the weather forecast for the location of the house to develop a DR strategy that is more effective than prior DR strategies. In addition, a computational experiment system is described that generates DR strategies based on various energy consumption models and simulated energy usage data for the house and compares the cost effectiveness and energy usage of the generated DR strategies.
