Abstract: A method for delimiting and monitoring at least one working area for at least one autonomously operated vehicle includes transmitting, by a transmitter and receiver unit, an output signal through a signal loop. The transmitter and receiver unit is arranged outside the vehicle and is connected using signaling technology to the signal loop. The method further includes comparing the transmitted output signal with an input signal received from the signal loop, determining, by the transmitter and receiver unit, a malfunction of the signal loop in response to a deviation between the output signal and the input signal, and initiating a securing sequence for the autonomous driving operation of the at least one vehicle.

Abstract: An emergency stop system for transferring an at least semi-autonomously operable vehicle into a safe state includes an actuating device configured to output an actuating signal, a control device configured to receive the actuating signal and to output a control signal, and an emergency braking device configured to actively brake the vehicle. The emergency braking device is configured to actuate a braking system provided in the vehicle based on the output control signal and based on a predetermined operating mode in order to generate a braking force for decelerating the vehicle.

Abstract: A method for controlling an autonomous agricultural machine, which is configured to not traverse a predetermined geographic boundary, includes determining a trajectory of a moving object in surroundings of the agricultural machine. The method further includes determining a trajectory of the agricultural machine, determining a predicted collision point between the agricultural machine and the moving object based on the trajectories, and adapting a planned trajectory of the agricultural machine such that an adapted collision point lies on another side of the boundary relative to the agricultural machine.

Abstract: A control unit for a motor vehicle having a microprocessor that comprises at least two computation cores, a monitoring module that is separate from the microprocessor, an evaluation module for evaluating input signals provided by sensors, and an activation module comprising at least one end stage for producing output signals to activate actuators. A control function is implemented in a first computation core, a monitoring function for the first computation core of the microprocessor is implemented in the second computation core of the microprocessor, and a monitoring function for the second computation core of the microprocessor is implemented in the monitoring module. Starting from the first computation core and/or starting from the second computation core and/or starting from the monitoring module, a switch-off module can be activated to switch off the at least one end stage of the activation module.

Abstract: The present invention discloses a filter having multiple layers including an odor suppressing layer for use with a plurality of different types of air flow inducing devices. One filter layer acts as a standard air filter to filter contaminants out of an air flow. Another filter layer serves as an odor suppressing layer to reduce odors in the air flow. An optional additional layer adds structural integrity to the filter while also supplying additional filtration of particulate.

Abstract: The present invention discloses a filter assembly which includes a compartmented housing structure having a plurality of inlets and an outlet. A first inlet is positioned in flow communication with a first chamber portion and a first filter member. A second inlet is positioned in flow communication with a second chamber portion and a second filter member. A third chamber portion is located between the first and second filter members and is in flow communication with the outlet such that ambient air entering the housing through the first and second inlets will flow through the first and second filter members into the third chamber portion and through the outlet.

Abstract: Apparatus to achieve both more uniform and particle free DLC deposition is disclosed which automatically cycles between modes to effect automatic removal of carbon-based buildups or which provides barriers to achieve proper gas flow involves differing circuitry and design parameter options. One ion source may be used in two different modes whether for DLC deposition or not through automatic control of gas flow types and rates and through the control of the power applied to achieve maximum throughput or other desired processing goals. Arcing can be controlled and even permitted to optimize the overall results achieved.
