Abstract: The invention relates to a pinch protection method and device for a motor-driven closing system. The method comprises the following steps: detecting a reduced motor speed, switching off the motor, analyzing a sensor signal for detecting a pinch situation, deciding whether a pinch situation is present, and controlling the motor depending on the detection of a pinch situation. The device for detecting a pinch situation comprises a motor, a detection unit, a control unit and at least one sensor. The device is adapted to carry out the method according to the invention.
Abstract: A spark plug for an internal combustion engine includes a ground electrode, a center electrode, an insulator, a housing, and a folded packing which is situated on an outer circumference of the housing. The folded packing has: a hollow profile in cross section; a free leg directed outwards; and a support region. The folded packing lies on a contact surface in a support region, and the free leg is situated at an angle to the support region. The folded packing is pressed together during the mounting of the spark plug, and the free leg of the folded packing is designed to bend over in the direction of the support surface during the mounting to provide a diameter enlargement of the folded packing.

Abstract: Network node control is described that includes node wakeup scheduling that reduces the energy consumption of levels of nodes and reduces the delay of information transfer through the network. The node wakeup scheduling includes a crossed ladder pattern that combines two wakeups in one level. The node wakeup scheduling also includes an adaptive version of the crossed ladder pattern that changes the wakeup patterns of the crossed ladder over time to provide uniform energy savings. The network node control also includes the use of multiple trees to transfer information through a network. This multi-parent node assignment assigns multiple parents with different wakeup schedules to each node in the network. This multi-parent assignment reduces the delay in transmission of information through the network and also increases energy efficiency in the nodes.
