Abstract: Handheld welding gun for welding an element to a component comprising a linear actuator unit with a linear actuator housing and a linear actuator rod adapted to actuate the holding unit in order to move the element between the lift position and the plunge position, the linear actuator rod extending partly inside and partly outside the linear actuator housing. A displacement measuring system communicates with a control card. The linear actuator, the displacement measuring system and the control card are connected together to form a compact actuator unit.

Abstract: Disclosed are automated processes and systems for the assembly of composite doors, and doors made using such processes and systems. The automated process may comprise a continuous series of steps allowing individual doors to be made in tandem, rather than in batch. The process may allow for the automation of individual steps such that the need for coordinating separate assembly steps may be substantially reduced.

Abstract: The invention relates to a method and a device for controlling the cornering speed of a vehicle, with determination of the lateral acceleration and of the speed of the vehicle. In order to achieve a simple but effective capability of adjusting the vehicle speed to an optimum value, the yaw angular velocity is additionally determined, and a body slip angle is determined from the lateral acceleration, yaw angular velocity and vehicle speed. The body slip angle is compared with a threshold value. If the body slip angle exceeds this threshold, the set speed of the vehicle is reduced from the instantaneous actual speed, in a manner proportional to the body slip angle. If the body slip angle is below the threshold, the speed is released once again, or in other words the set speed is carried to the actual value of the speed; the driver can then accelerate once again. Adjustment of the set speed is achieved via adaptation of the engine torque.

Abstract: A method of controlling travel behavior of a vehicle provides assistance to the driver of the vehicle before the occurrence of travel conditions which are difficult to control. A vehicle taking a curve tends not to follow the travel curve indicated by steering, often resulting in understeering as the travel speed increases. At very high speeds in a curve, such behavior can lead to conditions that are difficult for the driver to control. Rather than intervening when an unstable travel state is already present and control of the vehicle rendered difficult, as practiced in conventional systems and processes for the regulation of travel dynamics, the wheel brake of a rear wheel of the vehicle on the inside of the curve is already subjected to a weak braking force when a relatively minor tendency to understeer occurs, so that the understeering tendency is reduced or eliminated.

Abstract: Implementation of a travel dynamics control system in a vehicle is facilitated by integration of same with other operational components of an electrically controlled vehicle braking system. In an embodiment of the invention, travel dynamics electronics are integrated with the braking system electronics. In another embodiment, a yawing speed sensor and a transverse acceleration sensor are integrated with the travel dynamics electronics.

Abstract: A method for the processing of sensor signals in a digital electronic system including a microprocessor, in which computed magnitudes are derived from the signals emitted by the sensors, and wherein the magnitudes are compared with one another to recognize certain travel situations. In order to carry out these comparisons simply and reliably using an economical microprocessor and cost-efficient sensors while applying simple computing steps, the comparison of two magnitudes derived from the sensor signals is carried out first on a level of the representation of one magnitude, for example, an angular yawing speed, and a second time on a level of the representation of the other magnitude, such as, for example, a steering angle. By this method, one comparison result supports the other. The method is advantageously used in a vehicle with a device for the control of travel stability, and preferably for the recognition of reverse travel.
