Abstract:
The present invention is concerned with enterprise gamification and relates to a method of optimizing operation of a work environment with multiple roles comprising each a number of scoring tasks. The invention proposes mapping of application gamification scores across different job roles within a work environment by means of suitable weighting or calibration factors. This renders comparable the scores of enterprise employees having different job roles and ultimately enables organization-wide gamification.

Abstract:
Converter stations (104) have real and reactive power set points initially determined as part of a main loadflow analysis routinely performed on the AC power system connected to the converter stations (104). Viable real and/or reactive power set points for the converter stations (104) can be identified by calculating real and/or reactive power set point candidates for the converter stations (104) before the main loadflow analysis is performed again on the AC power system. The power set point candidates are calculated based on information determined as part of a previous iteration of the main loadflow analysis on the AC power system. The power set point candidates which violate an operating constraint imposed on the AC power system are identified, and a region of valid power set points is defined for the converter stations (104) that excludes the power set point candidates which violate an operating constraint imposed on the AC power system.
Abstract:
Among other things, one or more techniques and/or systems are provided for developing a health profile of an industrial asset based upon data pertaining to such an industrial asset. At least some of the data is transformed into primary state indicators, respectively representative of the status or condition of an aspect of the industrial asset. Using the primary state indicators, one or more events that are likely to occur to the industrial asset are identified and a health profile is developed based upon such events. The health profile may describe maintenance actions that will reduce a likelihood of an event(s) occurring, may describe a business impact on an entity associated with the industrial asset if an event(s) occurs, and/or may describe a performance impact on the industrial asset if an event(s) occurs, for example.
Abstract:
A programmable logic controller (14) for an industrial control system (10) comprises an application logic execution layer (42) and at least one of an update checking layer (40) and an output checking layer (44). The application logic layer (42) is adapted for receiving sensor input data (32) from at least one sensor (16) coupled to the programmable logic controller (14) and for processing the sensor input data (32) to generate an output parameter (30) for an actuator (18). The output checking layer (44) is adapted for receiving the output parameter (30), for checking the output parameter, whether the output parameter is an allowed output parameter corresponding to a list (52) of allowed output parameters; and for outputting only an allowed output parameter to the actuator (16). The update checking layer (40) is adapted for receiving application logic update data (50), wherein the application logic update data contains information for updating the application logic (43). The update checking layer (40) is adapted for checking the application logic update data (50), whether the application logic update data is allowed application logic update data, by verifying, whether every application logic update defined by the application logic update data (50) corresponds to an application logic update in a list (48) of allowed logic updates, and for updating the application logic (43), only if the update data is allowed application logic update data.
Abstract:
The invention comprises a method for communication between a wireless device node in a wireless sensor network (WSN) and control apparatus or control processes of an industrial control system. The method is used to determine a method of radio transmission which provides a greater or a lesser measure of transmission quality between nodes. Thus a transmitter node a) measures(30) a transmission quality metric of at least one packet received from two or more different switching branches, b)identifies (32) which of the two or more switching branches has the greater transmission quality metric, c) distributes (34) data packets with a first priority to the switching branch with the greater transmission quality metric, and d) transmits (38) data packets with the first priority such as real-time data on the switching branch with the greater transmission quality metric. In other aspects of the invention a wireless node, a sensor network system and a computer program for carrying out the method are described.
