Patent number: 11267306Abstract: A vibration damper in a wheel suspension of a vehicle, which damper is supported on a wheel-guide element of the wheel suspension via two resilient bearings which are provided laterally of a damper tube of the vibration damper and which are diametrically opposed in relation to the damper tube. Each bearing has a rubber-elastic bearing element in which a damper receptacle is supported which is force-transmittingly connected to the damper tube. The damper receptacle is supported on the damper tube via a releasable securing element.Type: GrantFiled: February 28, 2020Date of Patent: March 8, 2022Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Jens Kallert, Alfred Stenzenberger, Gerhard Zeller

Patent number: 10414231Abstract: A support of a vehicle, in particular of a motor vehicle, is provided with a recess for accommodating a container that is embodied as an air equalization container. The container has connecting points, which are located in a first plane of the container and are designed to connect to the support. The container is designed as a supporting component, and further includes other connecting points in a second plane that is spaced apart from the first plane, the other connecting points being formed for the connection to the support of the vehicle.Type: GrantFiled: December 30, 2016Date of Patent: September 17, 2019Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Ingo Lauer, Gerhard Zeller, Marc Erdmann

Patent number: 9386734Abstract: An electronic device comprises a substrate (120), at least one electronic component (171, 172, 173) arranged on the substrate, and an encapsulation (140) covering the at least one electronic component (171, 172, 173). An electromagnetic protective layer (130) covers a surface (143) of the encapsulation (140) that faces away from the substrate (120), and the side faces (121, 141; 122, 142) directed transversely with respect to the surface (143). In particular, a thermal and/or electrical coupling (134, 162, 163, 164, 165, 166) couples the electromagnetic protective layer (130) thermally and/or electrically to a region (168) of the electronic device (111, 112) that is enclosed by the encapsulation. For production purposes, the device is singulated from a panel and the electromagnetic protective layer (130) is subsequently applied.Type: GrantFiled: July 27, 2011Date of Patent: July 5, 2016Assignee: EPCOS AGInventors: Claus Reitlinger, Gerhard Zeller

Patent number: 9184483Abstract: A directional coupler, comprising a first high-frequency line for feeding a first high-frequency signal, a second high-frequency line for feeding a second high-frequency signal, and a coupling line for outputting signals from the first and the second high-frequency lines, wherein the coupling line comprises resistive segments, each comprising a predetermined impedance. Coupling properties and resistive damping and adapting properties can be integrated in the coupling line. A compact and low-cost construction of the directional coupler is thus made possible.Type: GrantFiled: November 21, 2011Date of Patent: November 10, 2015Assignee: Epcos AGInventors: Gerhard Zeller, Manfred Stadler, Edgar Schmidhammer, Pasi Tikka

Patent number: 9142887Abstract: A front end module for a wireless transmission/reception device has two antennas and two signal paths connected thereto. A mismatch in the antenna is identified by monitoring the transmitted power and the reflected power in the active and passive signal paths and using the powers in a controller to generate a control signal for the antenna tuner. In this case, decreasing isolation between the first and second antennas and the first and second signal paths is identified, and is compensated for using different devices, in order to ensure faster and safer antenna matching.Type: GrantFiled: April 12, 2010Date of Patent: September 22, 2015Assignee: EPCOS AGInventors: Pasi Tikka, Gerhard Zeller

Patent number: 8891412Abstract: A circuit arrangement for a mobile radio device includes a first transmission path for a first communication system with TDD duplex operation and a second transmission path for a second communication system with FDD duplex operation. The first transmission path contains a first transmission filter and the second transmission path contains a first duplexer. The first and second communication systems use transmission frequency bands that are arranged within the same octave. A transmitted signal from the first communication system can be routed switchably and thus either via the first or the second transmission path.Type: GrantFiled: April 22, 2010Date of Patent: November 18, 2014Assignee: Epcos AGInventors: Pasi Tikka, Christian Block, Andreas Przadka, Gerhard Zeller, Peter Hagn

Publication number: 20130293317Abstract: The invention relates to a directional coupler (1), comprising a first high-frequency line (2) for feeding a first high-frequency signal, a second high-frequency line (3) for feeding a second high-frequency signal, and a coupling line (4) for outputting signals from the first and the second high-frequency lines (2, 3), wherein the coupling line (4) comprises resistive segments (5a-5c, 15a-15c, 25a-25c, 35a-35c, 45a), each comprising a predetermined impedance. Coupling properties and resistive damping and adapting properties can be integrated in the coupling line (4).
