Publication number: 20170234904Abstract: A speed sensor for detecting a speed of a magnetizable object. The speed sensor (100) can be supplied with an electric alternating signal with a first frequency by an electric signal source. The speed sensor including: a primary coil for generating a magnetic alternating field with the first frequency; first and second secondary coils. The first and second secondary coils can each be magnetically coupled to the primary coil via a magnetizable object. First and second electric signals induced in the first and second secondary coils respectively by the generated magnetic alternating field; a Goertzel filter bank detects first and second amplitude values of respective spectral components of the induced first and second electric signals in the event of a second frequency which differs from the first frequency. A processor determines the speed of the magnetizable object depending on the detected first amplitude value and the detected second amplitude value.Type: ApplicationFiled: September 22, 2015Publication date: August 17, 2017Inventor: Frank Grunwald

Patent number: 9601251Abstract: At least two partial magnets mechanically connected to each other. The length of each partial magnet runs in the main magnetisation direction of each partial magnet and/or in the main direction in which a partial magnet can be magnetised or in which its magnetisation is intended, and defines a first side and a second side as opposed regions at the ends of the partial magnet in respect of its length The at least two partial magnets are arranged in sequence in respect of their lengths and connected to each other. Deviations in the direction of the magnetisation and/or magnetisability of the first partial magnet deviating from the main magnetisation direction and/or main direction of magnetisability reduce and/or substantially compensate for the deviations in the direction of the magnetisation and/or magnetisability of the other or of the adjacent partial magnet deviating from the main magnetisation direction and/or main direction of magnetisability.Type: GrantFiled: December 9, 2013Date of Patent: March 21, 2017Assignee: Continental Teves AG & Co. oHGInventor: Frank Grunwald
