The invention relates to a method for determining a damage state of components, wherein damage states are determined for a component on the basis of operating states of an overall system that comprises the component by determining time-normalised stress collectives and/or load collectives for each operating state (ZBB), wherein, by means of the time-normalised stress collectives and/or load collectives for each operating state (ZBB) the damage state is determined for the component on the basis of operating states of the overall system that have occurred, and/or the prospective damage state is determined on the basis of predicted prospectively occurring operating states of the overall system that comprises the component, and/or the damage state is determined for a further component, designed similarly to the aforementioned component, depending on operating states that have occurred of a further overall system, which comprises the further component and is designed similarly to the aforementioned overall system, and/or the prospective damage state is determined on the basis of predicted prospectively occurring operating states of the further overall system that comprises the further component.

A method for synchronizing a simulation of a simulation model on a computer with a real-time system, the simulation and the real-time system each having a computing clock having a matching macro increment. The method includes the following features: awaiting a message from the real-time system, measuring a receiving instant of the message by the simulation, awaiting at least one further message of the real-time system, measuring the receiving instant of the further message by the simulation; calculating an averaged receiving instant based on the receiving instants of the message and the at least one further message; determining a starting instant of the simulation based on the averaged receiving instant such that the results of a macro increment of the real-time system are available to the simulation at the start of a macro increment.

A system for use with a vehicle includes at least one device installed or present onboard the vehicle and configured to sense or determine at least one condition or characteristic of the vehicle or its driver. The at least one device communicates the condition or characteristic with a remote site or web service using a wireless communication device. The remote site or web service correlates or compares the condition or characteristic of the vehicle or its driver with road conditions, capacities, facilities, and/or established safety data associated with the upcoming roadway, and determines whether the vehicle should stop or enter a facility due to an incompatibility or conflict between the condition or characteristic and the road conditions, capacities, facilities, and/or established safety data. The remote site or web service then communicates the determination of whether the vehicle should stop or enter the facility to the device on the vehicle.

Provided are a controller and a program with which it is possible to easily output the state of mechanical loss in an induction motor. A controller for controlling industrial machinery that has an induction motor comprises: an electric power cutoff unit that cuts off the supply of electric power to the induction motor; a speed acquisition unit that acquires the speed of the induction motor; an acceleration calculation unit that calculates acceleration on the basis of the acquired speed; a moment-of-inertia acquisition unit that acquires the moment of inertia of a spindle of the induction motor; a mechanical loss calculation unit that calculates mechanical loss in the induction motor on the basis of the acquired speed, the calculated acceleration, and the acquired moment of inertia; and an output unit that outputs the calculated mechanical loss.

A physical quantity measuring device includes a chip package and a casing. The casing fixedly stores the chip package. The casing includes a first bypass passage allowing a gas to be measured taken from a main passage, to flow in a first measuring unit, and a second bypass passage allowing the gas to be measured taken from the main passage, to flow in a second measuring unit. The chip package is configured to dispose a signal processing unit between the first and second measuring units. The casing has a cooling unit that allows the gas to be measured from the main passage to flow between the first measuring unit and the second measuring unit, and cooling the signal processing unit.

Systems and methods for testing a valve using valve signatures are provided. An analytical device receives a first valve signature from a portable measurement device. The portable measurement device obtains the first valve signature by causing a plurality of control signals to be applied to the valve and receiving data representing actual positions of the valve corresponding to the applied control signals. The analytical device may generate an image including a graphical representation of the first valve signature and a second valve signature that was measured prior to or after the first valve signature.
