Patents by Inventor CHRISTOPH RIEHL

CHRISTOPH RIEHL has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240011803
    Abstract: A position transducer, a linear actuator and a method for determining a position of two components in relation to each other. The position transducer having measuring unit and a first, second, and third electrode assembly. The third electrode assembly capacitively couples the first and the second electrode assemblies to each other and is movable in relation thereto. The measuring unit is electrically conductively connected to the first electrode assembly by a first line assembly and to the second electrode assembly by a second line assembly. The measuring unit is configured to emit at least one excitation signal via the first line assembly and receive at least one readout signal via the second line assembly. The measuring unit is also designed to determine, based on readout signal, a position of the third electrode assembly in relation to the first and the second electrode assemblies.

  • Patent number: 11697576
    Abstract: A telescopic lifting unit with a first segment, a second segment, and a third segment. The first and second segments may be displaced relative to one another, and the second and third segments may be displaced relative to one another. The first and second segments may be moved relative to one another by a motor unit, and the second and third segments may be moved relative to one another by a cable hoist.

  • Patent number: 11680827
    Abstract: A position sensor for a linear actuator, a production method for a position sensor, a linear actuator with a position sensor, and a method for determining a position of a linear actuator. The position sensor has a capacitor arrangement and a data processing device. The capacitor arrangement has a first capacitor element and a second capacitor element arranged to be movable relative to the first capacitor element and designed to generate a capacitive signal. A data processing device is configured to determine the position of the second capacitor element relative to the first capacitor element based on the capacitive signal. The second capacitor element is made of an electrically conductive polymer.

  • Patent number: 11664714
    Abstract: A position sensor includes first and second sensor components. The second sensor component has a reading unit that is configured to evaluate a capacitive signal in relation to the position of the second sensor component relative to the first sensor component. The position sensor is in addition configured to provide the result of the evaluation at an interface of the first sensor component. A method for ascertaining a position of a second sensor component of a position sensor relative to a first sensor component of the position sensor as well as a linear actuator, are provided.

  • Patent number: 11131563
    Abstract: A linear system includes a linear unit and a motor adapted to drive the linear unit so as to perform a linear movement. A system for detecting the position of the linear unit includes an absolute encoder which is connected to the motor. The absolute encoder is configured so as to detect a position of the linear unit based on a movement of the motor.
