| 20120086326 | Method for Manufacturing a Spark Plug and Spark Plug Manufactured Accordingly - Method for manufacturing a spark plug comprising an inner conductor, an insulator enclosing the inner conductor, a spark plug body enclosing the insulator, and two electrodes, the first electrode being a center electrode connected to the inner conductor in an electrically conductive manner, and the second electrode being a ground electrode connected to the spark plug body in an electrically conductive manner, with a separately prefabricated precious metal component positioned on one of the electrodes and connected to the electrode by way of resistance welding, and subsequently affixed by way of laser or electron beam welding, so that the precious metal component extends like a heel beyond the electrode surface next to the precious metal component. The precious metal component, a ball, is shaped by stamping after resistance welding and before laser or electron beam welding, wherein at least one region of the ball protruding from the electrode surface (is reshaped. | 04-12-2012 |
| 20120060598 | METHOD FOR ALLOCATING IDENTIFIERS OF WHEEL ELECTRONICS OF A TIRE PRESSURE MONITORING SYSTEM OF A VEHICLE TO THE POSITIONS OF ABS SENSORS ON THE VEHICLE - Allocates identifiers of units of a tire pressure monitoring system to the positions of ABS-sensors which are each assigned to the wheels of the vehicle. The identifiers are contained in signals that are emitted by the units. Each unit, which is called a wheel electronic, has a pressure sensor, which is sensitive to the tire pressure of the wheel, a motion sensor, which provides information on the rotation speed of the wheel, a memory with the individual identifier of the wheel stored therein, and a transmitter, which transmits signals only containing information on the rotation speed of the respective wheel, to a receiver. An evaluation device receives the transmitted identifier and compares the information on the rotation speed of the wheel transmitted along with the identifier, with rotation speed information, which were acquired by the ABS sensors for the same time span and transferred to the evaluation device. | 03-15-2012 |
