Publication number: 20240093450Abstract: The device for the migration of aquatic animals has a channel body with an upstream end and a downstream end as well as a longitudinal axis. The bottom of the channel body is provided with a cover layer made of natural bottom substrate and/or debris material and has a ridge running along the longitudinal axis. Plate-shaped lamellae are arranged in the channel body transversely to the longitudinal axis of the channel body. The lamellae have a downwardly open lower cut-out, which is limited at the top by a transverse element, wherein the cross-sectional area of the lower cut-out is dimensioned in such a way that the ridge of the cover layer may be accommodated in the lower cut-out. The upper edge of the transverse element has a preferably curved contour, which is inclined towards the centre of the channel and defines a lower boundary of an upper cut-out of the lamellae extending upwards from the transverse element.Type: ApplicationFiled: September 19, 2023Publication date: March 21, 2024Inventors: Georg SEIDL, Christoph WAGNER

Patent number: 10199968Abstract: In some examples, an alternator control device includes interface configured to receive a voltage signal from an engine control device, pull-down circuitry, and a switch electrically connected between the interface and the pull-down circuitry. The alternator control device further includes processing circuitry configured to determine that the voltage signal is higher than a threshold voltage level and to activate the switch to electrically connect the interface to the pull-down circuitry in response to determining that the voltage signal is higher than the threshold voltage level. The processing circuitry is further configured to determine that, at least a threshold time duration after activating the switch, the voltage signal is higher than the threshold voltage level and to refrain from delivering the excitation current based on determining that, at least the threshold time duration after activating the switch, the voltage signal is higher than a threshold voltage level.Type: GrantFiled: May 22, 2017Date of Patent: February 5, 2019Assignee: Infineon Technologies AGInventors: Christoph Seidl, Amir Hasanovic, Sebastian Jandl, Karl Lamisch

Patent number: 10169278Abstract: One aspect of the invention relates to a network node for connecting to a Local Interconnect Network (LIN). In accordance with one example of the present invention, the network node includes a bus terminal which is operably coupled to a data line for receiving a data signal, which represents serial data, via that data line. The data signal is a binary signal having high and low signal levels. The network node further includes a receiver circuit which employs a comparator to compare the data signal with a reference signal. The comparator generates a binary output signal representing the result of the comparison. The network node also includes a measurement circuit that receives the data signal and provides a first voltage signal such that it represents the high signal level of the data signal.Type: GrantFiled: July 31, 2013Date of Patent: January 1, 2019Assignee: INFINEON TECHNOLOGIES AGInventors: Alexander Mori, Christoph Seidl

Patent number: 9929685Abstract: A fault protection circuit for an alternator is provided for preventing faults such as a prolonged full-field condition in the alternator. The fault protection circuit includes a safety switch that is opened when the alternator output voltage becomes too high, as may occur during a full-field condition caused by an electrical short, or when some other fault is detected within the alternator. The opening of this safety switch disconnects a supply voltage feeding an excitation current control switch. The excitation current control switch normally adjusts an excitation current provided to a rotor in the alternator, in order to regulate a voltage output from the alternator. By providing a safety switch that disconnects the supply voltage for the rotor excitation in the alternator, the alternator output voltage may be prevented from reaching excessive levels that may damage devices in an electrical system and a battery coupled to the alternator.Type: GrantFiled: June 10, 2015Date of Patent: March 27, 2018Assignee: Infineon Technologies AGInventors: Martin Graefling, Christoph Seidl
