Abstract:
1. Method to control electrical devices using three-dimensional motion detection of an object inside a monitoring area subdivided into a detection area and an attached pre-detection area, by a detection system that comprises a distance measurement system and a control device, comprising: starting a main cycle of the control method by bringing the control device from a hibernation state into a standby state if a presence of an object inside the monitoring area is expected, carrying out of an identification distance measurement using the control device that is in standby state at a first time t carrying out a verification distance measurement using the control device that is in standby state for verification of an identified object as inside the detection area at a second time t starting of a measurement cycle of the control method by bringing the control device into an operating state upon verification that the identified object is inside the detection area, wherein the operating state is characterized by a higher power input than in standby state and the standby state in turn is characterized by higher power input than in hibernation state, and in operating state the necessary highest power possible is supplied for the control method, carrying out a distance measurement to determine a position measurement of the object inside the detection area, starting of control of an electrical device by generating an output signal which serves as a control of the electrical device, and finishing the main cycle of the control method and bringing the control device into the hibernation state.
