Abstract: A method for activating a drive unit of a deflection unit of a two-dimensional microscanner device. First and second control signals for activating the drive unit of the deflection unit are initially generated using a processing unit. The first and second control signals are subsequently transferred to the drive unit. A sinusoidal first movement of the deflection unit about a first axis and a sinusoidal second movement of the deflection unit about a second axis are carried out at a first point in time based on the transferred control signals. The first control signals are then adapted so that a periodic third movement is superimposed on the first movement at a second point in time following the first point in time. Alternatively, the second control signals are adapted so that a periodic fourth movement is superimposed on the second movement at the second point in time following the first.

Abstract: A method for manufacturing a shaker device using 3D-printing (i.e., additive manufacturing). An electromagnet is formed by producing a bobbin body and winding an electrical conductor on the bobbin body to form an electromagnet coil. A cylindrical body is 3D-printed and the bobbin body with the electromagnet coil is coupled within an interior of the cylindrical body. A piston assembly is then positioned within the bobbin assembly. The shaker device is operated by controllably applying a magnetic field through the electromagnet coil that impinges a permanent magnet of the piston assembly to cause movement of the cylindrical body relative to the piston. By using these 3D printing techniques, the composition of materials can be varied within a single component part, fine structural details can be included in the components, and components can be 3D printed directly on each other to eliminate tolerance issues relating to small variations in component size.

Abstract: A device for controlling an automated driving operation of a vehicle may have at least two brake systems, at least two steering systems, an engine controller, a first automated drive controller, a second automated drive controller, a surroundings sensor assembly, and inertial sensors. A third automated drive controller at least controls the vehicle into a standstill. The device is configured such that the automated driving operation is initiated and/or maintained only when the brake systems, steering systems, and at least two of the automated drive controllers are functional and such that the automated driving operation is interrupted if only one of the automated drive controllers is functional and/or if one of the brake systems and/or steering systems is not functional and/or if the engine controller is not functional, in which case the still functional automated drive controller assumes control of the vehicle and guides the vehicle into a standstill.

Abstract: A method for operating an exhaust gas sensor in an exhaust system of an internal combustion engine of a vehicle. The exhaust gas sensor includes a ceramic sensor element having at least one measuring electrode and a heating device. A binary dewpoint end signal is calculated, based on data which relate to the internal combustion engine and the exhaust gas sensor, which indicates whether or not the occurrence of liquid water in the exhaust system is still to be expected. Whenever the vehicle is turned off and the dewpoint end signal simultaneously has the value which signals that the occurrence of liquid water in the exhaust system is still to be expected, the sensor element is heated by its heating device to a temperature for a certain period of time in such a way that the sensor element dries.

Abstract: Systems and methods for monitoring the quality of water or leaks within a household plumbing system via machine learning are provided. Appliances can be connected to a plumbing system, wherein each appliance includes one or more sensors configured to output sensor data regarding a property of the water being utilized by that appliance. A processor is programmed to receive the sensor data and establish boundaries of normal operation. Then, when additional sensor data is received, the processor uses machine learning to classify that sensor data as being either within normal operation, or outside the bounds of normal operation. If the sensor data indicates the water property is outside the bounds, an output signal can be generated to inform the user.
