Abstract: A process and device for monitoring the state of a wheel of a motor vehicle in which an output signal of a sensor is converted into an essentially rectangular pulse signal. A respective duration of the pulse is measured; and an especially weighted average between the duration of a current value and a preceding value is determined, wherein a current value and a preceding value exhibit a time interval and/or lie a specific step size apart. A correction factor is determined from each deviation between the duration of a current value and a respective mean value. A step size of the correction method is matched to an error order of a fault. Preferably the step size with a periodic deviation of the mth order that is to be eliminated is determined according to the formula j=1/m×n/4; for motor vehicles in particular according to the formula j=1/m×12.

Abstract: A servo-controlled impacting device for orthopedic implants includes one or more sensors, an impacting device, and a controller with an interface. The controller is configured to provide control signals to an impactor in response to feedback signals from at least one sensor proximate an orthopedic implant subject to a force applied by the impactor. The interface is coupled to the controller and is configured to enable parameters to be set related to the operation of the controller.

Abstract: In a method and apparatus for detecting shock absorber damage, features of a shock absorber are determined by analyzing a signal of an antilock braking system rotational wheel speed sensor.

Preferably the step size with a periodic deviation of the mth order that is to be eliminated is determined according to the formula j=l/m×n/4; for motor vehicles in particular according to the formula j=l/m×12.
