A monitoring system includes at least one three-dimensional (3D) time-of-flight (TOF) camera configured to monitor a safety-critical area. An evaluation unit is configured to activate a safety function upon an entrance of at least one of an object and a person into the monitored area and to suppress the activation of the safety function where at least one clearance element is recognized as being present on the at least one of the object and the person.

Monitoring system

A method for calibrating a three dimensional time-of-flight camera system mounted on a device, includes determining at a first instant a direction vector relating to an object; determining an expected direction vector and expected angle for the object to be measured at a second instant with reference to the device's assumed trajectory and optical axis of the camera; determining a current direction vector and current angle at the second instant; determining an error represented by a difference between the current direction vector and the expected direction vector; and using the error to correct the assumed direction of the main optical axis of the camera system such that said error is substantially eliminated.

A vibration sensor () for monitoring the state of rotating components or bearings, includes a housing (), a sensor element (), evaluation electronics (), and at least one interface (). With the vibration sensor (), reliable monitoring of the state of rotating components and bearings can be done easily and economically, and in addition the vibration sensor can be easily operated. The evaluation electronics () has an analog-to-digital converter (), and a signal conditioning device () having a plurality of signals, which have been acquired by the sensor element (), and which are converted into a state value using signal analysis and a diagnosis algorithm.
