A diagnosis system is configured to diagnose an apparatus including a driver device. The system includes an acquisition unit configured to acquire waveform data indicating a waveform related to a current to be supplied to the driver device, and a determination unit configured to determine a condition of the apparatus. The determination unit is configured to obtain, based on the waveform data, a change caused by a component of a force in a particular direction applied to the driver device, and to determine the condition of the apparatus based on the obtained change. The diagnosis device determines the condition of the apparatus accurately.

A measurement device measures a physical amount of each of a plurality of attachment target members to be attached in a circumferential direction of a rotating main body portion. A storage member capable of storing the plurality of attachment target members is placed on a placement portion. A measurement unit measures the physical amount of the attachment target member. A transfer unit transfers the attachment target member between the placement portion and the measurement unit.

The present subject matter provides various technical solutions to technical problems facing sensor-based vehicle safety technology. To address problems facing identification of safety features (e.g., safety sensors) for a particular vehicle, a vehicle safety feature identification system may be used to identify a vehicle and the safety features that are installed on that vehicle. To address problems facing identification of which safety sensors require maintenance, a vehicle safety feature maintenance system may be used to identify vehicle safety sensors based on information received about one or more vehicle repairs, such as structural repairs following a vehicle collision. The vehicle safety feature maintenance system may use image data or other inputs to identify a vehicle repair area, identify other vehicle components that must be removed or adjusted to complete the vehicle repair, and identify all vehicle safety sensors and other safety features that will need to be repaired, replaced, or recalibrated.

A method and system for inspecting deviation in dynamic characteristics of a feeding system are provided, and the method includes: exciting the feeding system and detecting vibrations of a subcomponent of a component to be inspected of the feeding system to generate a monitoring excitation signal in a monitoring mode; calculating, by a modal analysis method, monitoring eigenvalues and monitoring eigenvectors of the monitoring excitation signal; determining, by a modal verification method, similarity between the monitoring eigenvalues and standard eigenvalues of a digital twin model and similarity between the monitoring eigenvectors and standard eigenvectors of the digital twin model; determining that the dynamic characteristics of the subcomponent are deviated, when the monitoring eigenvalues and monitoring eigenvectors are not similar to the standard eigenvalues and standard eigenvectors. Therefore, the subcomponent whose dynamic characteristics are deviated can be sensed remotely and precisely.
