A method for testing a technical system. Tests are carried out with the aid of a simulation of the system. The tests are evaluated with respect to a fulfillment measure of a quantitative requirement on the system and different error measures of the simulation. On the basis of the fulfillment measure and each of the error measures, a classification of the tests is carried out as either reliable or unreliable case by case. A selection among the error measures is made on the basis of a number of the tests classified as reliable.

A method for automatically creating installation-specific measuring profiles for an insulation monitoring system, includes: assisting in a computer-controlled manner by means of an assist system via guided instructions for acquiring installation data; and executing the instructions by means of one more sensor devices. The method further includes pre-selecting, assisting, recording, evaluating, detecting, and optimizing steps.

A simulation testing architecture can be applied to an aircraft monitoring system for an aircraft that includes complex algorithms (such as machine learning algorithms) for sensing objects around the aircraft and controlling the aircraft to avoid such objects. A reference scenario is selected from a plurality of stored scenarios based on a desired set of aircraft safety standards. A stochastic process is applied to generate a large number of conditional variations within a simulated environment, varying weather, objects in the airspace, points of failure, and the like to provide a representative sample of possible aircraft missions and encounters within the selected reference scenario. Synthetic environmental inputs are fed into the aircraft monitoring system software, and the resultant actions of the software are logged. These logs can be used to generate metrics on an encounter-level basis, a scenario-level basis, or across a population of scenarios.

A building management system is provided. The building management system includes one or more variable air volume units and a controller. The controller includes a processor and a memory. The memory stores processor executable instruction. The processor executable instruction when executed by the processor cause the building management system to perform functional tests on the one or more variable air volume units of the building management system to generate building data; analyze the building data to produce health information per functional test; and visualize a condition of the building system based on the health information.

Methods and systems for validating component integrity in an engine are described. First usage data associated with a period of operation of the engine is obtained at an engine controller. An indication of the first usage data is transmitted from the engine controller to a first presentation device. Second usage data associated with the period of operation of the engine is received at the engine controller from an input device. The first usage data is compared to the second usage data at the engine controller. Based on the comparing, an alert is issued to a second presentation device independent from the first presentation device.

An input device including an input circuit with an input connection point for applying an input signal and with an input signal path which leads from the input connection point to an evaluation input and on which a conversion of the input signal into an evaluation signal is effected, an evaluation device which includes the evaluation input and which is designed to recognise an input signal level of the input signal on the basis of the evaluation signal, wherein the evaluation device is further designed to carry out a functionality test of the input device and within the framework of the functionality test by way of providing a test signal to effect a first change of the evaluation signal and to test the functionality of the input device on the basis of the effected first change of the evaluation signal, wherein the input circuit includes a transistor which is connected into the input signal path, and the input circuit is designed to control a control terminal of the transistor on the basis of the test signal, in order to effect the first change of the evaluation signal.

A method of controlling monitoring of a vacuum system, the vacuum system, and the monitoring control system are disclosed. The method comprises: selecting at least one of a plurality of processes for monitoring the vacuum system from a data store storing the plurality of processes. Executing the at least one selected process Wherein one of the at least one selected processes comprises a process for monitoring a parameter of the vacuum system and for responding to changes in the parameter to trigger at least one of: execution of a further one of the plurality of processes; output of an alarm or notification signal; and output of a control signal for controlling operation of at least one component of the vacuum system.

Apparatus and associated methods relate to generating a wiring schema with more than one safety device sharing at least one test signal through one or more external terminal blocks when the number of terminals required by safety devices exceeds the number of available terminals of a safety controller. In an illustrative example, the method may include determining a total number of terminals A of safety devices to be connected to a safety evaluation device having a number of terminals B. If A is greater than B, the method may then include generating a wiring schema that one or more external terminal blocks may show indicia of electrical connections between an identified set of safety devices and a shared terminal of the safety evaluation device associated with that set. Various embodiments may advantageously expand a number of devices to be connected to the safety evaluation device.

A crash sensor device may include multiple sensor components positioned along one or more data paths to a communication interface of the crash sensor device. The crash sensor device may include a test control unit. The test control unit may receive a test command from an electronic control unit during operation of a vehicle. The test control unit may perform a test of one or more sensor components, of the multiple sensor components, during operation of the vehicle based on the test command. The test control unit may output a test result to the electronic control unit based on performing the test.

A method can include perturbing an electric motor of a hybrid powerplant having the electric motor and a fuel powered engine. The method can include measuring a frequency response of the powerplant due to the perturbing of the electric motor to determine a health of the powerplant and/or one or more components thereof.
