Abstract: A base plate is to be fixed to the ground at the edge of a swimming pool. A starting block can be fixed on the base plate. The base plate includes in an inner cavity, measurement electronics with at least one force or motion sensor or at least one strain gauge, to provide a measurement signal to a processor processing unit of an electronic circuit to determine one or more race parameters to be stored in a memory of the electronic circuit and/or to transmit wirelessly or wired to the base station or a timing station.

Abstract: A method for adapting a contact point of a clutch in a drivetrain of a motor vehicle, wherein the clutch is moved by an actuator and the influence of the movement of the clutch on a rotating electric motor is evaluated. A method that is simple and quick to carry out, a clutch torque and/or an actuator path close to the contact point is obtained from a characteristic curve of the clutch representing the relationship of an actuator path to a clutch torque and is set at the clutch. Subsequently the associated actuator path and/or the clutch torque is measured from the clutch influenced by the actively operated electric motor, where the clutch torque read from the characteristic curve and the actuator path measured at the clutch and/or the actuator path obtained from the characteristic curve and the measured clutch torque form the current contact point position of the clutch.

Abstract: A method and device for controlling a shiftable planetary gear set in a belt drive of an internal combustion engine in a motor vehicle having a sun gear which is fixedly connected to a belt pulley, a ring gear which can be connected fixedly with respect to the housing by means of a brake which is activated by an electrically operated actuator which is effective along a distance which is monitored by a relative distance sensor, as well as a web which is connected to a crankshaft of the internal combustion engine and rotatably accommodates planetary gears, wherein situated between the sun gear and the web is a free wheeling mechanism which can be switched and rolled over in both directions and is switched by the same actuator along the travel distance.
