20130134967 | METHOD AND CIRCUIT ARRANGEMENT FOR CHECKING THE ROTOR POSITION OF A SYNCHROUNOUS MACHINE - A method for validating a vehicle-to-X message, in which the message is received by an antenna arrangement having a least two antenna elements connected with a communication device. An electromagnetic field strength of the message is recorded based on different reception characteristics with different power densities, wherein the message includes an absolute position of a transmitter, and an absolute position of a receiver determined on the basis of global satellite navigation or on a map comparison. A first relative position of the transmitter is calculated from the absolute positions of the receiver and the transmitter. A second relative position is calculated from the ratio of the power densities or read out from a reference diagram. If a comparison of the first and second relative positions reveals a large degree of correspondence, the message is validated, and if a large degree of deviation is detected, the message is rejected. | 05-30-2013 |

20150316371 | METHOD FOR DETERMINING THE ABSOLUTE POSITION OF A LINEAR ACTUATOR - A method for determining the absolute position of a linear actuator is described. In the process, the rotational angle position of the rotor of the corresponding electric motor of the linear actuator is determined by a first sensor. In addition, the rotary angle position of a transmitter wheel of a second sensor coupled to the rotor is determined by means of a special transmission ratio. The absolute position of the linear actuator is derived from the differential value of the determined rotary angle positions. The method can be implemented in a simple and inexpensive manner. | 11-05-2015 |
