Abstract: A brake system is disclosed herein. The brake system includes an electromechanical brake actuator, a pressure plate, an end plate, a ball screw positioned between the electromechanical brake actuator and the pressure plate, and a plurality of rotating discs positioned between the pressure plate and the end plate. The electromechanical brake actuator is configured to extend the ball screw to a ball screw position to apply a requested force to the pressure plate towards the end plate thereby forcing the plurality of rotating discs together in an axial direction in order to reduce a rotational speed of the plurality of rotating discs. The ball screw is extended by the electromechanical brake actuator to the ball screw position based on a worn state of the plurality of rotating discs and a stiffness curve for the electromechanical brake actuator that represents force versus ball screw position for the worn state.

Abstract: A method for controlling brake assemblies of a vehicle is provided. Responsive to identifying a locked wheel protection event for a first wheel of a paired set of wheels on the vehicle, where the paired set of wheels is the first wheel on one side of the vehicle and a second wheel on an opposite side of the vehicle, a first brake pressure to a first brake assembly associated with the first wheel is released to zero pounds per square inch (PSI) and a second brake pressure to a second brake assembly associated with the second wheel of the paired set of wheels is reduced by a predetermined amount thereby reducing a yaw effect to the vehicle.

Abstract: A method of controlling an aircraft braking system includes initiating the aircraft braking system by receiving a first brake command at a primary system to actuate braking via the primary system, receiving the first brake command at an alternate system, and in response to the primary system losing an ability to control a brake, controlling the braking of the brake via the alternate system.

Abstract: An aircraft braking system is disclosed that includes a first pedal, first and second pedal sensors for the first pedal, a first brake control unit (e.g., primary), and a separate second brake control unit (e.g., secondary). The first pedal position sensor is operatively interconnected with one of the first brake control unit and the second brake control unit, while the second pedal position sensor is operatively interconnected with the other of the first brake control unit and the second brake control unit. Outputs from these pedal sensors may be used to control operation of the aircraft braking system in at least some fashion.

Abstract: A method of determining the trim set value of a vehicle body leveling system comprising the steps of: receiving a trim set command; responsive to the trim set command, retrieving a sensor output from a vehicle height sensor; determining a difference value between the sensor output and a predetermined offset, wherein the offset is indicative of an effect an average sized operator would have on the vehicle height as measured by said height sensor; and programming the difference value into a memory of a level control system, wherein the programmed value is the trim set value for the level control system.

Abstract: A neural network provides automatic control of a windshield wiper. A rain sensor generates sensing signals indicating a rain pattern, and the neural network generates wiping demand signals indicating a wiping action desired by the driver. A training unit uses manually generated wiping supervision signals to create weight factors for the neural network.
