A computer-based method for automated hazard detection for a technical system, the method includes the step of selecting an output failure mode of a component of a component fault tree of the technical system as a top level hazard. The computer-based method includes the step of generating a hazard information tree by means of a subtree of the component fault tree, wherein the subtree is selected by means of the top level hazard, wherein the subtree is modified by removing predefined nodes from the subtree and by enhancing output failure modes of the subtree with information from which component the output failure modes originate, wherein the modified subtree is saved in a memory unit as hazard information tree. The computer-based method includes the step of evaluating the hazard information tree, and providing a control signal comprising a result of the evaluation.

Technology is configured to facilitate monitoring of operational parameters and maintenance conditions of physical infrastructure. Some embodiments relate to an arrangement of hardware and software that are configured to perform monitoring of physical infrastructure operational parameters via a first set of sensor devices, and periodically write data to a blockchain, in combination with a second set of sensor devices that are configured to monitor for defined maintenance conditions, which are also written to the blockchain. This is preferably used as a means to drive determination of a reliability/availability measure for the infrastructure, and/or automatedly perform payment transactions for maintenance operations.

A wireless power initiated test system can use an aircraft controller to automatically initiate a test sequence to determine status of systems of the aircraft, based on the detection of receipt of the wireless power at the aircraft. The detection of receipt of the wireless power at the aircraft can be based on the detection at a voltage regulator of the aircraft which is receiving the wireless power from a wireless power receiver of the aircraft. The system may also power the aircraft controller during the test sequence using the wireless power received. Such a system may quickly and efficiently initiate, power and perform a pre-flight test sequence to determine statuses of systems of the aircraft, such as during a competition or race of the aircraft. The system may apply to drones, as well as of other types of aircraft.

A system includes a controller configured to control an operation of a turbine system, and an analytics system coupled to the controller and configured to receive inputs corresponding to the operation of the turbine system, generate an operational impact factor (OIF) value based at least in part on the inputs, generate a turbine system life prediction model configured to predict an operating life of one or more components of the turbine system based at least in part on the OIF value, and provide the OIF value to the controller to perform an action based thereon.

A centralized voltage controller connected, via a communication network, to local voltage control units controlling voltage controllers, which are connected to a distribution line of a distribution system and control voltage of the distribution line, has: a voltage distribution determination unit calculating a controlled amount for each first voltage controller to be controlled among the plurality of voltage controllers, based on a measured value of voltage at each point of the distribution line; a tap position determination unit generating a command value to be given to each local voltage control unit based on the controlled amount; and a control state determination unit determining whether each voltage controller is a second voltage controller that fails to perform control according to the command value, and setting the voltage controllers except the second voltage controller to be the first voltage controller.

A method and apparatus for analysing utility consumption at a utility supply location is described. The method comprises the steps of: receiving utility consumption data corresponding to utility consumption at the utility supply location over a time period to be analysed; generating a recurring consumption model indicative of repeating consumption patterns in the utility consumption data; identifying divergences between the utility consumption data and the recurring consumption model; computing a diagnostic measure indicative of irregular consumption based on the identified divergences; and outputting the diagnostic measure. The diagnostic measure may be used to identify flexibility or irregularities in consumption and/or to control supply of the utility. The utility may be e.g. electricity, gas or water.
